The traditional polyurethane manual infusion molding process is as follows: first prepare the production material, the production mold, the release agent used for demolding during production, the mixing cup, and the heating equipment and electronic scale for measurement and other materials and equipment. . Then weigh material A, add material B according to the proportion after weighing, and weigh again. Then use a mixer to mix the two materials to achieve uniform mixing, and finally pour them into the mold to form. During the whole process, a series of problems such as inaccurate weighing and mixing of uneven materials may occur.
Polyurethane foaming machine
Small polyurethane foaming machine is a special equipment for two-component polyurethane infusion foaming. You only need to pour the polyurethane material into the mold according to a certain proportion through our machinery and equipment, or into the designated product, and you can produce uniform and qualified foam products. It is made of polyether polyol and polyisocyanate in the presence of a variety of chemical additives such as blowing agent, catalyst, emulsifier, etc., through chemical reaction to foam to prepare foam. The small polyurethane foaming machine can be used for automobile interior decoration, thermal insulation wall spraying, pipe thermal insulation production, and bicycle seat sponge processing.
The polyurethane foaming machines produced on the market are uneven. How to choose a high-quality, low-price, and good-service equipment is a job that every buyer hopes for, so how can we do it? Let’s say If you can start from the following aspects, I believe there will be a good result. First of all, now is the age of brands. It is always a good choice to buy a well-known brand, and it is also the choice of most people. Don't worry, so don't try to be cheap when buying foaming machines, try to choose well-known brand polyurethane foaming machines.
When the polyurethane foaming machine is operated early, the material is the combination of polyurethane black and white materials. Be careful when operating. Especially when operating isocyanates, you should pay special attention, because it has a certain irritation, do not inhale Its steam, and do not splash on the skin and eyes. In case of leakage and touch, we should also deal with it in time. The specific treatment methods are as follows:
When the skin touches the combined polyether, wash it with soap and water;
When splashing on the skin and eyes, it is necessary to wipe it off with a sanitary napkin immediately, then rinse it with plenty of water for 15 minutes, and then rinse it with soap or alcohol. If it is still serious, it should be treated immediately;
When a large area of isocyanate is sprinkled on the ground, use sand and wood chips to cover up, and then wash the ground with a lot of water;
When clothes are contaminated with isocyanate, it is necessary to treat it with a solution containing 50% ethanol, 45% water, and 5% concentrated ammonia, and then wash it with a pan.
