How to choose the right foaming equipment?
How to choose a suitable polyurethane high pressure foaming equipment? How much is a polyurethane high pressure foaming equipment?
1. Drive mode: Foaming equipment has the difference between hydraulic drive and pneumatic drive. Hydraulic drive is more stable than air drive.
2. Parameter setting: Many parameters can be changed according to user needs. The calculation and estimation of polyurethane high-pressure foaming equipment are usually determined according to the user's equipment configuration and parameters.
3. Determine the purpose of the equipment: For example, it can be ordinary spray insulation materials and ordinary products, but it is recommended to use polyurethane high-pressure foaming equipment in the production of tile shells, profile pouring and polyurethane, with the function of timing and quantitative production of foam.
Small polyurethane foaming equipment is classified into spraying type and pouring type according to the spray state of raw materials from the nozzle of polyurethane foaming equipment: polyurethane spraying foaming equipment and polyurethane pouring foaming equipment.
Application of spray-type polyurethane foam equipment: polyurethane foam insulation for building exterior walls, integration of polyurethane foam insulation and waterproofing for roofs, polyurethane foam insulation for cold storage, polyurethane foam insulation for grain depots and various ceilings, etc.;
Application of perfusion type polyurethane foaming equipment: perfusion filling of solar water heater barrel interlayer insulation layer, thermal insulation water tank, car portable refrigerator, beer barrel, security door, cabinet, plate, on-site foam packaging, plate, etc.
The price of polyurethane high-pressure foaming equipment varies, and you should choose the appropriate equipment according to your own needs. The foaming of polyurethane high-pressure foaming equipment is a relatively complex physical and chemical reaction process. Therefore, it is very important to master the control points of polyurethane high-pressure foaming equipment. Changes in raw materials, molds, preheating temperature and curing time selected to eliminate mechanical failures are also directly related to the foaming quality of polyurethane high-pressure foaming equipment.
First of all, understand the combination of polyisocyanate, polyether and foaming agent in black and white materials of polyurethane high-pressure foaming equipment, the chemical properties of catalyst and foam stabilizer directly determine the chemical reaction of synthetic polyurethane and the physical properties of foam. It is necessary to choose a well-known foam material company, and foam material is the basic condition for producing qualified polyurethane foam.
Secondly, strictly control the mixing ratio and injection amount of the original solution of the polyurethane high-pressure foaming equipment, control the black raw material, and combine the mixing ratio of polyether and cyclopentane. When the total injection volume is constant, cavitation will occur when the proportion of black substances is too large, soft bubbles will appear when the proportion of white substances is too large, expansion bubbles will appear when the proportion of cyclopentane is too large, and when the proportion of black and white materials is not When equilibrated, the mixture will become uneven and the foam will shrink.
