Ib qho polyurea txheej / elastomer yog tias muab faib los ntawm cov tshuaj tiv thaiv cov khoom ntawm ib qho isocyanate tivthaiv thiab cov khoom siv sib xyaw ua ke. Cov isocyanate tuaj yeem yog cov ntxhiab lossis aliphatic hauv qhov. Nws tuaj yeem yog monomer, polymer, lossis ib qho txawv txav ntawm isocyanates, quasi-prepolymer lossis prepolymer. Cov tshuaj polymer, lossis quasi-prepolymer, tuaj yeem ua cov amine-teminated polymer cob, lossis ua kom muaj cov hydroxyl-txiav tawm polymer cob.
Cov tshuaj pleev ua ke yuav tsum yog ua los ntawm amine-teminated polymer resins, thiab / lossis amine-terminated polymer resins yuav tsis muaj lub hom phiaj hydroxyl moeness. Cov hydroxyls yog qhov tshwm sim ntawm qhov tsis tiav hloov mus rau amine-txiav npluav polymer resins. Cov paj tov sib xyaw ua ke kuj tseem muaj cov tshuaj ntxiv, lossis cov khoom siv tsis zoo. Cov additives no tuaj yeem siv hydroxys, xws li cov xim ua ntej-dispersed nyob hauv polyol cov cab kuj. Nquag, cov roj hmab sib xyaw yuav tsis muaj catalyst (s).
Shamu muaj qhov hnyav ntawm cov khoom lag luam polyurea rau kev tiv thaiv kev txhim kho, tiv thaiv kev ntxhib los mos thiab tsis muaj dej. Peb tseem muaj Qtech-416 rau cov xim pleev kom zoo nkauj. Qtech-416 tuaj yeem thov hauv lub txee hais lus.
