How to make plastic particles into mesh bags

Plastic particles are divided into: granulation and raw materials, and waste plastics must be processed first. Color, ingredients are all very important things.

The question you are asking is a plastic factory, I don't know if you are the production and processing of plastic bags or just the granulation processing of plastics, if it is a production and processing in one, the cost of 200,000 is not necessarily possible, and the required production and processing processes are also very complex. It can be divided into: granulation processing, film blowing processing, finished product processing and so on.

There are also a lot of small processing projects involved. Need to actually see other people's factories, talk to technicians. If it is simple granulation and raw material processing 20w is possible, the machine is not very complicated.

Technicians are important, and the cost budget mainly depends on whether you are good at running a business. The amount of money made is based on the timing of grasping the market, and the line of plastics in recent years....

The plastic particles are first melted at high temperature to stretch the plastic particles. The specific temperature will vary according to different plastic particles. PP is different from PE.

After drawing, it is slit, braided, and woven into a roll film, and then it needs to be cut according to the size of the bag. I perform sewing afterwards and am ok and become the finished product. Regarding the specific process details, involving the temperature of the extruder die, the speed of the slitting machine and other detailed issues, it is recommended that you go to the PP forum to find experts to communicate.

The name of finance is particularly loud. Finance is generally a specific term for economic behavior at the local and national levels, and the expenditure of ordinary households must not be raised to the level of "fiscal".

Finance literally embodies a kind of domineering, so the main disciplines of public finance study more or less have the concept of "country", such as international economics, public finance, national economic management, national budget, tax management, international taxation, state-owned asset management, etc.

Boys have strong logical thinking, strong hands-on ability, and can be engaged in work with high work intensity, these advantages also determine some majors suitable for boys to study, and the following is a list of the top ten majors suitable for boys.

1. The most recommended is the IT industry, the rapid development of China's economy in recent years is inseparable from the support of information technology, the information age, the background of big data, and all industries are inseparable from the support of Internet technology, from the basic office of the company to the front-end technology and software development. Boys' natural logical thinking ability can be said to be very suitable for learning.

2. The auto repair industry, the market in this industry is relatively large, and the market demand is relatively large, and it is not a problem after completing the study, and you can even open your own shop and start a business.

3. West Pastry Baking 4, Beauty Salon 5, Railway Aviation 6, Medicine 7, Accounting 8, Marine Engineering 9, Fire Engineering 10, Mechanical Engineering.

Generally, the gap of the cold stamping die can be taken 10% of the thickness of the material without special requirements, and the thicker the stamping material, the greater the percentage of the clearance value, for example, when the material thickness is in between, the gap value is 9% 12%; When the thickness of the material is between, the gap value is 12% 14%; When the thickness of the material is between 4mm and 6mm, the gap value is 15% to 18%. According to this calculation, the gap of your mold is too small, and it is easy to break the mold. As for the tonnage of the punch, it is not easy to judge whether it is enough because I don't know the size of the work you are stamping.

The gap is related to the thickness of the plate, and the thicker the plate, the larger the gap.

Generally unilateral.

Hard material t<1mm unilateral clearance (6-8)%t

t=1-3mm, unilateral clearance: (11-17)%tt=3, 5mm, unilateral clearance: (17-25)%t, hard materials, refers to steel, iron, etc.

Fuzhou University.

In recent years, Fuzhou University has basically ranked around 70th, and the province has always been second, after all, Xiamen University is better. Fuzhou University is basically in the middle of all the 211 universities, and its strength in science and engineering is strong.

Campus distribution. Founded in 1958, Fuzhou University is one of the three key universities in Fujian Province under the Ministry of Education of the People's Republic of China, and a first-class university in Fujian Province.

As of May 2019, Fuzhou School has multiple campuses in Fuzhou, Qishan, Yishan, Tongpan, Xiamen Jimei, Gulangyu, Quanzhou Quangang and Jinjiang, covering a total area of more than 7,000 acres and a total area of 1.42 million square meters of public buildings. The total value of fixed assets is 3.9 billion yuan, of which the value of teaching and scientific research instruments and equipment is 1.3 billion yuan; It has 21 colleges (including 1 independent college) with 84 undergraduate majors; It has 1 national key discipline, 1 national cultivation (key) discipline, 11 postdoctoral mobile stations, 11 first-level discipline doctoral programs, 39 first-level discipline master's programs, and 12 professional degree authorization programs; There are 3,161 faculty members, 24,164 students, and nearly 10,500 doctoral and master's students. From the perspective of floor area and the number of graduate students, Fuzhou University occupies a great advantage, the general colleges and universities cover an area of 3000-4000 acres, the total area of Fuzhou University is equivalent to the sum of the area of the two universities, and the number of graduate students is very large, the total number of doctoral students and master's students has reached more than 10,000, and the scientific research ability is also quite good.

According to the results of the fourth round of discipline evaluation of national universities released by the Academic Degree Center of the Ministry of Education, Fuzhou University has 24 disciplines on the list. Among them, there is 1 A-class discipline, 11 B-level disciplines, and 12 C-level disciplines. In this discipline evaluation, 150 universities participated in the discipline of chemistry, and 7 first-class universities including Fuzhou University, Shanghai Jiao Tong University and Nanjing University entered the A-grade, ranking in the top 10% of the country.

The subject ranking rate has increased significantly, and the chemistry discipline has increased from the top 24% in the third round of discipline evaluation to the national ranking of 5% and 10%; Management Science and Engineering and Business Administration were respectively promoted from the top % in the third round of discipline evaluation to 10% and 20% in the national rankings. Mathematics, mechanical engineering, and civil engineering have risen from the top % in the third round of subject evaluation to 20% and 30% respectively in the national rankings. Law, Electrical Engineering, and Electronic Science and Technology have risen from the top % in the third round of discipline evaluation to 30% and 40% respectively in the national rankings. The disciplines of computer science and technology and Marxist theory entered the fourth round of discipline evaluation list.

The above-mentioned disciplines are all science and engineering disciplines and economic management disciplines that play an important supporting role in the regional economic development and pillar industries of Fujian Province.

Therefore, Fuzhou University is still a good 211 university.

I am a student who graduated from Fuzhou University 10 years ago. I have been to Tsinghua University, Peking University, Zhejiang University and briefly visited. In terms of the campus environment, there is little difference. However, the most important human environment and learning atmosphere are very different.

In Fujian Province, it is a good choice, but outside the province, the popularity is limited. Choose it, don't go for the 211 title, but for the professional.

A good major, it is true that the road to the future will be easier. The comprehensive strength of a university is not only its teaching quality, but also the level of alumni and social recognition. Fuzhou University has a good predecessor in the province, they are excellent in their positions and academics, basically have obtained a master's degree or above, and it is a 985 university.

A school is a platform, how much energy can be on this platform, you still have to rely on yourself, there are people in the school who love to learn, and there are people who play games all day long. It's up to you to become a student. Out of society, no one will accommodate themselves.

Recently, my brother said that he wanted to apply for Fuzhou University, but he didn't know about this university, and he didn't know if it was suitable for him, so what about Fuzhou University?
