What aspects of the pharmaceutical industry need to be anti static and why should it be anti static?

In the process of drug production in the pharmaceutical workshop, it is necessary to pay attention to cleanliness and anti-static, electrostatic discharge, electrostatic field, electrostatic attraction and other characteristics, which affect pharmaceutical equipment, monitoring instruments, drug quality, and may also cause solvent ** and other life-threatening accidents.

How do antistatic agents work? What are the good ways to prevent static?

Answer: First of all, let's find out what antistatic agents are on the market.

The main anti-static fluids in the Chinese market are: Nalute anti-static agent, ACL anti-static agent, Polyflix anti-static agent and Colcoat anti-static agent. Among these antistatic agents, Nalute antistatic agent is a washable antistatic agent.

Other antistatic agents are traditional antistatic agents. Nalut washable anti-static agent, even if rinsed with water or wiped with a damp towel, will not lose its anti-static function. The traditional anti-static agent cannot be washed with water or wiped with a wet towel, and if it is rinsed with water or wiped with a wet rag, it will lose its anti-static function.

Note: The antistatic agent mentioned here refers to the externally coated antistatic agent, commonly known as antistatic liquid.

Let's talk about the working principle of antistatic agents.

According to the different mechanism of action of antistatic agents, the working principle of antistatic agents can be divided into the following two categories:

1.Reduce the coefficient of friction, make it difficult for glass fiber to generate static electricity, cationic quaternary ammonium lubricants and imidazoline lubricants have anti-static effects.

2.A conductive channel is formed, so that the charge can be quickly removed from the surface of the fiber. For organic antistatic agents, such as polyoxyethylene castor oil, polyoxyethylene laurate, polyethylene glycol, etc.

They all contain ether segments, which are easily combined with moisture in the air through hydrogen bonds and form conductive channels, and these hygroscopic organic compounds can be used together with ionic quaternary ammonium salts, tertiary amine salts or carboxylate organic compounds to achieve better antistatic effects. The other most commonly used antistatic agent isand other inorganic salts, which have a strong tendency to form hydrates and become salts with crystalline water.

In other words, it has strong moisture absorption, and it dissociates into ions while absorbing water on the sizing film, so the conductive effect is very good.

What are the good ways to prevent static?

A good way to prevent static electricity is to apply an antistatic agent.

Ordinary antistatic agent is a surfactant, its molecule is composed of a lipophilic (plastic-philic) group composed of a long carbon chain and a hydrophilic polar group. When the antistatic agent is added to the plastic, the lipophilic group can be compatible with the plastic, when the antistatic molecule migrates from the plastic to the surface, the hydrophilic group can absorb water from the air, when the humidity in the air reaches a certain value, the surface of the plastic will form a thin layer of water that can not be distinguished by the naked eye, because the water layer contains some impurities, it can provide a leakage path. Therefore, the leakage performance of the plastic surface depends on this layer of water, which also depends on the humidity of the air in the use environment.

2. Due to the working principle of ordinary antistatic agents, it has caused its instability that cannot be changed. That is, the antistatic effect changes with the change of air humidity. When the relative humidity of the air is above 80%, the water absorption capacity of the antistatic agent is greater than the volatile ability of the water, add a small amount of antistatic agent, the surface of the plastic can obtain a good antistatic effect, the surface resistance is about 108 1010, when the relative humidity of the air is 60% 80%, the water absorption capacity of the antistatic agent and the volatilization ability of the water are comparable, the surface of the plastic can obtain a certain antistatic effect, when the relative humidity of the air is below 60%, The water absorption capacity of the antistatic agent is weaker than the volatile ability of water, and it can also be said that there is not enough water to contact the surface of the plastic, therefore, the antistatic properties of the plastic are relatively poor, or even none.

This is the biggest disadvantage of ordinary antistatic agents. Therefore, when plastics are required to have stable antistatic properties, permanent antistatic agents or inorganic conductive materials are generally used. 3. Testing standards for the performance of ordinary antistatic agents:

For these reasons, the performance of ordinary antistatic agents must be measured at a fixed relative humidity of the air. The international general testing standard is: air relative humidity 60%, temperature 25.

Antistatic agent manufacturers also follow this standard to ensure the quality of their products.

Static electricity, as a common natural phenomenon in nature, is beneficial and harmful. In this aspect, significant losses have been caused to society. Electrostatic discharge can cause damage to many electronic devices and instruments, and its damage forms include dust vacuuming, discharge damage, heat generated by discharge and electromagnetic field generated by discharge, which have hidden, latent, random and complex characteristics.

Therefore, in some workplaces, anti-static is a must.

1. In less than a month at the end of 1969, due to electrostatic discharge (ESD), three 200,000-ton super cruise ships in the Netherlands, Norway and the United Kingdom were washed one after another**;

2. Electrostatic discharge has caused dozens of satellites, such as the international communication satellite -F1-F8, the American Alnwick, and the European Space Agency's marine communication satellite, to malfunction and fail to fly normally.

3. The first Apollo manned spacecraft caused a fire due to electrostatic discharge, which killed three astronauts.

4. According to statistics in Japan, 45% of unqualified electronic devices are caused by electrostatic discharge hazards. In the electronics industry, the global cost of static electricity is up to 10 billion US dollars every year.

The anti-static protective equipment series can effectively prevent the electrostatic effect and avoid the harm caused by static electricity.

What is the difference between washable antistatic agents and ordinary antistatic agents?

Antistatic agents in this market can be classified into wash-resistant antistatic agents and ordinary antistatic agents according to their functions.

Washable antistatic agents include: Nalute antistatic agents.

Common antistatic agents are: Colcoat antistatic agent, Polyflex antistatic agent and ACL antistatic agent.

The main difference between washable antistatic agents and ordinary antistatic agents is whether they are resistant to washing.

Nalut washable antistatic agent, rinsed with water, or wiped with a washing towel, will not lose its anti-static function.

Ordinary antistatic agents cannot be washed with water, and if they are rinsed with water or wiped with a damp cloth, they will lose their antistatic function.

Note: The antistatic agent mentioned here refers to the externally coated antistatic agent, commonly known as antistatic liquid.

Let's talk about common antistatic agents.

What are the manufacturers of antistatic agents? What is the difference between an antistatic agent and an antistatic agent?

The antistatic agent mentioned here is actually only for liquid antistatic agents, that is, antistatic liquids.

Antistatic agent manufacturers are: Nalut antistatic agent, Baolifu antistatic agent, ACL antistatic agent and Colcoat antistatic agent. The antistatic agents of these manufacturers are good, and the effects are not bad, so if you want to buy antistatic agents, you should find these manufacturers.

NAIR antistatic agent is a wash-resistant antistatic agent, that is, rinsing with water or wiping with a damp towel will not lose its antistatic function. The antistatic agent of other manufacturers is a traditional antistatic agent, which is not resistant to washing, and will lose its antistatic function when rinsed with water or wiped with a wet towel.

There is no difference between antistatic agents and antistatic agents, just different names. This refers to liquid antistatic agents.
