Polyvinyl chloride rigid plate - Introduction
PVC rigid board is a material made of polyvinyl chloride (PVC), which has the following properties:
1. Weather resistance: PVC hard board has good weather resistance, can be used in different climatic conditions, and is not easy to be damaged by ultraviolet rays, acid rain and other factors.
2. Corrosion resistance: PVC hard board has good corrosion resistance, can withstand the erosion of acid, alkali and other chemicals.
3. High hardness: PVC hard plate has high hardness, good compression resistance and wear resistance.
4. Fire resistance: PVC hard board has good fire resistance, can resist combustion, and will not produce toxic gases.
The main uses of PVC rigid board include:
1. Building materials: PVC hard board is commonly used in indoor walls, ceilings, floors and other building decoration materials, with heat insulation, sound insulation, fire prevention and other functions.
2. Manufacturing: PVC rigid board can be used to make display stands, exhibition boards, billboards and other commodity display and promotional materials.
3. Packaging materials: PVC hard board can be used to make packaging boxes, trays and other items, with good compression resistance and durability.
The method of making PVC rigid board usually includes the following steps:
1. Raw material preparation: mix polyvinyl chloride resin and additives in a certain proportion.
2. High temperature melting: the mixture is heated to a certain temperature to melt it.
3. Extrusion molding: Extrude molten polyvinyl chloride through an extruder to obtain a hard plate of the desired shape.
4. Cooling and solidification: The extruded hard plate is rapidly cooled by the cooling device to solidify and form it.
In the use of PVC rigid board need to pay attention to the following safety matters:
1. Avoid prolonged exposure to high temperature to prevent deformation of the hard board.
2. Pay attention to fire safety, try to avoid contact with open flame.
3. Avoid contact with organic solvents, acids and bases and other chemical substances to avoid chemical reactions.
4. During operation and transportation, attention should be paid to avoid violent collisions to avoid damage.
