Polyurethane high-pressure foaming machine is a special equipment for infusion and foaming of polyurethane foam. Polyurethane high-pressure foaming machines are essential in many production areas. Polyurethane high-pressure foaming machine is a kind of precision equipment. In the actual operation process, there will inevitably be a lot of operation items, which need to be paid attention to in production, so as not to hinder normal production needs.
Precautions for the operation of polyurethane high-pressure foaming machine
1. When using polyurethane high-pressure foaming machine, you must wear protective goggles, work clothes and work caps, and rubber gloves to operate polyurethane A and B combined materials. The working environment must be well ventilated, clean and hygienic. When the ambient temperature is high, the foaming agent in the polyurethane A material will partially vaporize and generate pressure. Therefore, the vent cover should be opened to discharge the gas and release the pressure before opening the barrel cover.
⒉ When the polyurethane high-pressure foaming machine has flame-retardant requirements for the foam, the polyurethane foaming machine can use additive flame retardants. The addition amount of ordinary flame retardants is 15-20% of the weight of the white material, and the flame retardant is added to the polyurethane A material It must be stirred evenly before foaming,
3. During the manual foaming operation of the polyurethane high-pressure foaming machine, the polyurethane A and B combined materials are accurately weighed in proportion and poured into the container at the same time, stirred with a stirrer above 2000 rpm for 8 to 10 seconds, and then poured into the mold. The foam demoulding time depends on the product requirements and foam thickness.
4. When the skin comes into contact with the combined polyurethane A material, use soap and water to rinse. When the polyurethane foaming machine operates the polyurethane B material (it is a certain irritation), do not inhale its steam and do not splash it on the skin or on the eyes. When it splashes on the skin and eyes, wipe it off with medical cotton immediately, then rinse with plenty of water for 15 minutes, and then rinse with soap or alcohol.
