Polyurethane Introduction to the foam production process

Speaking of polyurethane foam I believe everyoneis no stranger, in our daily lives It is widely usedcan be found everywhere(Door and window installation, EngineeringDecoration, font>Landscaping and gardeningetc.), but not everyoneUnderstandIts production technology formula, product characteristics and how to use it correctly in the specific construction process. With the development of foam production technology , Polyurethane foam product performanceSubsequentlyhas been significantly improved , The product system is becoming more and more complete ,can be satisfied VariousConstruction Engineering、Door and window installation, Advertising model, Sound insulation, horticulture and landscaping, daily maintenance, waterproofing and sealing, packaging and transportation needs.

Polyurethane foam tube type and gun type, font>Tubular type comes with disposable hose,Gun type requireshair Foam gluespecialUse glueThe gun can only be used,The attached picture is ShanghaiWEIGGun type polyurethane foam, It is the intersection of aerosol technology and polyurethane foam technology.�The product of combination. A combination of polyurethane prepolymer, foaming agent, catalyst, etc. Special polyurethane products filled in pressure-resistant aerosol cans. It is often used for caulking, bonding, leak-proofing, etc. in the installation of doors and windows. Thermal insulation, sound insulation, waterproof.
Polyurethane foam production formula and process flow：
1. The process of producing foam rubber is white material filling Install→Black material filling→Seal→filled with dimethyl ether→filled with propylene butane →Threaded cap→Vibrator swing.
2. We usually refer to the foam formula as the white material formula, Black material is a kind of petroleum extract, yesBuy directly. The white ingredient formula can be prepared by yourself, White material technology is a specialized technology ,The pros and cons of white material technology Directly decidedproduct's quality and cost control, It isthe key.

With the rapid development of my country's synthetic resin industry,Foaming agents, like other plastic additives, present good development prospects and huge market potential. Single-component polyurethane foam is a kind of foaming agent technology and gas The product of a combination of aerosol technology, is widely used in the door and window caulking industry,Favored by the construction and decoration industry. The production process is simple,Easy to use. It is believed that styrofoam will be used more and more widely in the market in the future and its usage will increase.
