Polyurethane Hot Melt Adhesive (PUR): Ego ole ka ị maara

Polyurethane Reactiveaka PUR, Isi ihe dị na ya bụ end-isocyanate polyurethane prepolymer, nke nwere ike nrapado na mgbanwe dị mma, na mgbakwunye na nguzogide okpomọkụ dị mma, nkwụsị ihu igwe, mkpuchi mkpuchi, nkwụsị nke corrosion na ịka nká, ma jiri ya mee ihe na adhesives, mkpuchi, ụfụfụ, elastomers na ubi ndị ọzọ.

PUR bụ nke mejuputara macromolecular polyols, isocyanates, resins tackifying na obere ihe mgbakwunye na ihe ndochi.

Polyurethane Reactive(Pur) nwere ike kewaa ụzọ abụọ: otu bụ thermoplastic polyurethane elastomer na-ekpo ọkụ gbazee nrapado, na nke ọzọ bụ reactive polyurethane na-ekpo ọkụ gbazee nrapado. Reactive polyurethane na-ekpo ọkụ gbazee nrapado na-ekewa n'ime mechiri emechi ụdị na mmiri gwọọ ọkụ gbazee ụdị. Maka ụdị mechiri emechi, okpomọkụ nke dissociation nke ụdị mechiri emechi dị elu dị ka 100 Celsius C ma ọ bụ karịa, nke ga-eme ka afụ na oyi akwa nrapado, ya mere a na-eji ya naanị maka nlekọta nlekọta.
