Which types of work in the production of lead acid batteries need to wear dust masks

Dust masks must be worn in the ball mill workshop (grinding lead powder), plate cutting process, plate coating workshop and paste process, because there is more lead dust and lead powder, and it is easy to be poisoned by lead in the working environment. Other casting workshops, formation workshops, and assembly workshops can wear ordinary masks.

Lead powder workshop, coating workshop, slicing workshop, curing workshop, and assembly workshop should wear dust masks. Pig [piece workshop to wear a gas mask, otherwise it is also white belt,

In our factory, I saw that all their workers wore hats, masks, and gloves in the factory, in short, I felt that there must be harm to the human body, and the smell was very strong.

Workers on the production line should wear masks

Baianda dust masks are very good, and many battery factories are using them.

In addition to the normal business license and other certificates, it is necessary to obtain the "Industrial Product Production License" to be regarded as the legal production of lead-acid batteries. However, it may be difficult at present, and the country is rectifying lead-acid battery production enterprises.

Definition: The electrode is mainly made of lead and its oxide, and the electrolyte is a kind of battery with sulfuric acid solution. English:

lead-acid battery 。In the discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In the charging state, the main components of the positive and negative electrodes are lead sulfate. It is divided into exhaust batteries and maintenance-free lead-acid batteries.

The battery is mainly composed of tubular positive plates, negative plates, electrolyte, separators, battery slots, battery covers, poles, liquid injection covers, etc. The electrodes of the vented battery are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low price; The disadvantages are low specific energy (i.e. energy stored per kilogram of battery), short service life and frequent routine maintenance.

The life of the old ordinary battery is generally about 2 years, and the height of the electrolyte needs to be checked regularly and distilled water is added. However, with the development of technology, the life of lead-acid batteries has become longer and the maintenance is simpler.

The most obvious feature of a lead-acid battery is that it has a plastic seal on top that can be unscrewed, and there are vents on it. These fill caps are used for filling pure water, inspecting electrolytes, and venting gases. Theoretically, lead-acid batteries need to check the density and level of the electrolyte at each maintenance, and add distilled water if there is a deficiency.

However, with the upgrading of battery manufacturing technology, lead-acid batteries have developed into lead-acid maintenance-free batteries and gel maintenance-free batteries, and there is no need to add electrolyte or distilled water in the use of lead-acid batteries. It is mainly used to produce oxygen at the positive electrode, which can be absorbed at the negative electrode to achieve oxygen circulation, which can prevent the reduction of moisture. Lead-acid water batteries are mostly used in tractors, tricycles, car starters, etc., while maintenance-free lead-acid batteries are more widely used, including uninterruptible power supply, electric vehicle power, electric bicycle batteries, etc.

Lead-acid batteries are divided into constant current discharge (such as uninterruptible power supply) and instantaneous discharge (such as automobile starter battery) according to the application needs.

First, the measures are different, 1. New protectionism, also known as "super-protectionism" or "new mercantilism", was only emerging in the early 80s of the 20th century, with non-tariff barrier measures such as green barriers, technical barriers, anti-dumping and intellectual property protection as the main manifestations. 2. Protectionism, Protectionism mainly adopts tariff barriers and non-tariff barriers in terms of restricting imports. The former mainly prevents the large import of foreign goods by imposing high import tariffs, while the latter includes a series of non-tariff measures such as import licensing and import quota to restrict the free import of foreign goods.

Extended information: Causes of new protectionism: 1. Intensified international competition In the era of globalization, the market economy system has gradually evolved into the mainstream system of world economic development, and competition is one of the most important characteristics of the market economy, and has gradually evolved into the core motive for the survival and development of sovereign countries and enterprises, and has become an important means to realize national interests and enterprise interests. Countries not only protect their own industries and interests in international competition, but also directly intervene in the competition between their own enterprises and foreign enterprises.

On the one hand, the use of protective measures such as import tariffs or export subsidies is conducive to improving the earnings and market position of domestic enterprises. On the other hand, once foreign enterprises or imported products endanger their own interests, even developed countries will take direct intervention. In particular"Employment"Today, which has gradually evolved into a public good, the problem of unemployment caused by the increase in imports has become more and more prominent political significance. When domestic industries and labor groups are hit by imports, public outcry or other political pressure inevitably inclines the need to protect these areas against the threat of competition.

2. With the development of multinational corporations and their overseas operations, the flow direction and mode of international development have undergone profound changes, and the status of multinational companies in the international arena has been continuously improved. To a certain extent, the development of the international ** within the multinational corporation has changed the distribution of the international ** balance. Through the internal division of labor and accounting system, multinational companies have obtained relatively stable income internally, but they have thrown the difference between the books of various countries and the resulting friction to various countries.

The rapid growth of manufactured goods exports in Asia, which is one of the regions with the highest concentration of industrial transfer of multinational corporations, has enabled it to maintain a relatively large surplus with the United States and the European Union, and the exports of enterprises invested by multinational companies in Asia have become an important part of the deficit between the United States and the European Union. However, the policy of developed countries to deal with the deficit is not mainly aimed at these large multinational corporations, but to use exporting countries as an excuse to resolve disputes with these countries to promote new protectionism.

1. Traditional ** barriers.

a. Tariff ** barriers.

b. Non-tariff barriers: anti-dumping, anti-subsidy, safeguard measures.

2. New ** barriers.

Technological barriers, green barriers, social barriers and intellectual property rights are still barrier measures frequently used by developed countries to take advantage of their technological advantages.

Although tariff barriers protect the domestic economy, they only transfer losses to consumers and harm their interests. Non-tariffs are quantitative limitations.

In January 2010, the China-ASEAN Free Trade Area was completed.

The construction of the China-ASEAN Free Trade Area can be roughly divided into three stages. The first phase (2002-2010) was initiated and the tariff was significantly reduced. Since November 2002, when the two sides signed the China-ASEAN Comprehensive Economic Cooperation Framework Agreement with the China-ASEAN Free Trade Area as the main content, until January 1, 2010, China's tariffs on 93% of ASEAN products have been reduced to zero.

In the second phase (2011-2015), the FTA will be fully completed, that is, the vast majority of products from ASEAN, Vietnam, Laos, Cambodia and Myanmar and China** will also achieve zero tariffs, and at the same time, the two sides will achieve a more extensive and in-depth opening of the service market and investment market. The third stage (after 2016) is the consolidation and improvement stage of the free trade zone.

1. Find a solid backing for China's economic development, and at the same time, use China's strong economic strength to control and contain Southeast Asian countries and reduce losses when they are attacked from all sides!

2. Provide backing for safeguarding sovereignty in the South China Sea. China is the largest member of the Free Zone, so all countries are bound by China and have an advantage in dealing with the South China Sea issue.

3. In the Southeast Asian market, it can reduce the friction.

ASEAN-China.

The Free Zone, abbreviated as CAFTA, is a free zone established by China and the ten ASEAN countries.

The China-ASEAN dialogue began in 1991, and China became a comprehensive dialogue partner of ASEAN in 1996.

On January 1, 2010, the ** district was officially launched. [1] After the completion of the free trade area, ASEAN and China accounted for 13% of the world's largest free trade area, becoming a huge economy covering 11 countries, 1.9 billion people, and a GDP of 6 trillion US dollars.

There are three main types of payment for foreign trade exports: Letter of Credit (Letter of Credit), Telegraphic Transfer (Telegraphic Transfer), and Document Against Payment (Document Against Payment). Among them, l c is the most used, t t is second, and d p is less.

t t wire transfer. That is, the buyer remits the money directly from the country to your foreign currency account.

d p Collection. The seller gives the bill of lading and invoices to the bank, which entrusts the bank to collect the payment. However, if the buyer refuses to pay, the bank will simply return the documents to the seller.

l c Letter of credit. Guaranteed by the bank, the seller will be paid for the goods as long as the goods are delivered in accordance with the terms of the letter of credit, and the buyer will not have to pay for the goods before the seller fulfills the delivery obligations under the contract. A letter of credit is conditional, and a bank guarantee is a guarantee that the bank will pay the seller a sum of money immediately or at some future time at the request and instruction of the buyer.

The seller was given the money on the condition that he submit to the bank the documents specified in the letter of credit.

There are others like Remittance, Statement Against Acceptance A P, Bank Guarantee L G, which are rarely used now.

If there are 2 or more investors, the minimum registered capital of **** should be 30,000, and the minimum registered capital return of 100,000 yuan should be 100,000 yuan. Answer.

When registering a company, first go to the local industrial and commercial office to check the name and capital, then go to the industrial and commercial bureau where it is located to sign and apply for a business license, and finally go to the tax bureau for the record. It should be noted that the Inland Revenue Department (IRD) requires the company's accountant to go with it.

According to Article 26 of Chapter 2 of the Company Law, the minimum registered capital of 2 or more people is 30,000.

According to Article 59 of Chapter 2, Section 3 of the Company Law, the minimum registered capital of 1 person **** is 100,000.

In the revision of the Company Law in 2014, with the implementation of the capital subscription system, the limit of 30% of the registered capital has been abolished, that is, the registered company no longer requires the proportion of monetary capital contribution, nor does it limit the minimum amount of capital contribution (for special industries, the corresponding provisions need to be implemented), all shareholders subscribe and pay the capital contribution within the agreed period.

"Registered capital" refers to the amount of capital contribution actually paid by the shareholders of the collective ownership (joint-stock cooperative) enterprise; The monetary expression of the property operated and managed by the legal person of an enterprise owned by the whole people or collectively owned or all of it is the amount of property granted by the state to the enterprise legal person for operation and management or its own property.

According to the Company Law of the People's Republic of China, which came into effect in 2006, the minimum registered capital of a foreign trade company is 30,000 yuan.

Registered ** retail registered capital of 300,000 yuan Registered wholesale and retail is 500,000 yuan To obviously have the right to enter and exit in the business license is 1 million yuan Registered 500,000 yuan can enjoy import and export tax rebate reduction and exemption Registered capital does not play a big role If you register 500,000 yuan, then before you get the business license, you must cross 500,000 yuan Whether it is borrowed or a car, it is worth 500,000 yuan in kind, and when the license is done, you can withdraw the funds immediately Your company can still operate after bankruptcy But when you compensate for the bankruptcy, then your company only has 100,000 left, and it will only pay 100,000 The only role of the registered capital is to trade with the other party, and the other party feels that the more registered capital you have, the more assured you are, and the transaction does not play more role, understand.

Above bai

Said du is very zhi

Clearly, inside the dao, you look at the lower looks.

1. The concept is different.

CIF is called cost plus insurance plus freight, according to this term, the constituent factors of the price of goods include the usual freight and the agreed insurance premium from the port of shipment to the agreed port of destination, so the seller has the same obligations as the CFR term, but also for the buyer to handle freight insurance, pay the insurance premium, according to the general international practice, the seller should be insured according to the CIF price plus 10%.

CFR stands for Free Delivery on Board at the Port of Shipment, where the seller pays the cost of transporting the goods to the port of destination as indicated. But the risk of the goods is transferred at the time of delivery on board the ship at the port of shipment.

FOB is one of the commonly used terms in the international world. In the case of FOB transactions, the buyer is responsible for dispatching the ship to receive the goods, and the seller shall load the goods on the vessel designated by the buyer within the port of shipment and the specified time limit specified in the contract, and notify the buyer in a timely manner. When the goods are loaded onto the named vessel at the port of shipment, the risk passes from the seller to the buyer.

2. Fees and insurance premiums are different.

FOB** = purchase cost price + domestic expenses + net profit.

CIF** = purchase cost price + domestic expenses + foreign freight + foreign insurance premiums + net profit.

The insurance premiums in FOB terminology are the responsibility of the buyer and the seller shall notify the buyer before the goods are loaded on board. In CIF terminology, the seller is responsible for handling and paying the premium, and the seller takes care of the insurance and hands over the insurance policy to the buyer as stipulated in the contract.

The FOB price is converted to the CFR price = FOB price + foreign freight. CIF price = (FOB price + foreign shipping fee) (1 - insurance markup insurance rate). CFR price converted to other price, FOB price = CFR price, foreign freight.

CIF price = CFR price (1 - insurance plus insurance rate). CIF price converted to other priceFOB price = CIF price (1 - insurance markup insurance rate) foreign freight. CFR price = CIF price (1 - insurance markup insurance rate).

3. The time when the shipment notice is notified to the buyer is different.

FOB and CFR terms The seller is required to inform the buyer of the contents of the shipment and the details of the shipment before the shipment so that the buyer can have sufficient time to apply for marine insurance of the goods, while the CIF is the responsibility of the seller to inform the buyer of the notice of shipment within a few days after the goods are loaded on the ship.

When the transaction is closed according to CFR conditions, the seller arranges the transportation and the buyer handles the freight insurance. If the seller does not send a shipment notice in time, the buyer will not be able to apply for cargo insurance in time, and may even miss the cargo insurance. Therefore, the seller must send a notice of shipment to the buyer in time after loading the ship, otherwise, the seller should bear the risk and loss of the goods in transit.
