ПВХ: Вогнезахисне застосування та спосіб приготування полівінілхлориду
ПВХ, тобто, полівініл хлорид, is a common polymer with excellent flame retardant properties, and its flame retardant value can be as high as 40 or more. Among various materials, PVC is favored for its fireproof properties. У цьому документі, the application of PVC in fire prevention and the preparation of PVC paste polymer and basic lead carbonate are discussed.

PVC paste polymer:

PVC paste polymer is a branch product of polyvinyl chloride resin, named for its highly dispersed powder used in paste processing. This polymer is known for its excellent pasting properties and good dispersion, and is mainly used in the soft material field of PVC resin. PVC paste polymers in soft materials have excellent adhesion and are able to adhere firmly to a variety of surfaces, so they have a wide range of uses in the manufacture of flexible PVC products.

Suspension PVC:

Suspension polymerization of PVC is a loose resin. This loose resin has good oil absorption, dry flow, easy plasticity, and short molding time, making it very convenient in the production of PVC products. It is often used as the basic raw material for the molding of PVC products because it can be processed directly into powder and shows good properties in processing operations. This makes the manufacture of PVC products more efficient and economical.

Basic lead carbonate:

Basic lead carbonate, also known as lead white, has the formula 2PbCO3·Pb(OH)2. Проте, it is important to note that basic lead carbonate is toxic and therefore must be used with caution. It is often used in the field of fire prevention because of its excellent fire performance. Проте, to ensure its safe use, the relevant operating procedures and safety measures must be followed.

Preparation method:
Preparation of basic lead carbonate usually involves the following steps:

The raw material is added to the high speed disperser according to the predetermined ratio.

Under the condition of high speed stirring, the raw materials are mixed and evenly dispersed.

The slurry mixture is then placed in a sander, where it is ground and dispersed to the desired fineness.

This preparation process requires careful control of the ratio of raw materials and the mixing process to ensure high quality basic lead carbonate.

Сфера застосування:
PVC paste polymer and basic lead carbonate are widely used in the field of fire protection. Серед них, PVC paste polymer is usually used in the fire prevention treatment of coal mine ventilation pipes. This paste is able to adhere to the surface of the pipe, providing additional flame retardant properties, thus enhancing the fire safety of the pipe. В додаток, it can also be used as a paste for the walls of mining areas, further improving the overall level of fire prevention in mining areas.

Коротко, the application of PVC and its related products in the field of fire prevention is of great significance and helps to improve the fire safety of various facilities and materials. З постійним прогресом науки і техніки, we can expect that the performance of these fire-resistant materials will continue to improve, providing stronger fire protection for our social and economic activities. Проте, the use of these materials must strictly follow safety regulations to ensure the safety of people and the environment.
