Cov txheej txheem ntawm cov khoom siv raw uas siv hauv cov tshuab ntxhua tshuaj polyurea elastomer yuav tsum tau ntsib
(1) tsis muaj kuab, ob tog, nyob hauv chav kub lossis sov (<100 ℃)="" rau="" cov="" dej="" tsis="" muaj="">
(2) viscosity sib txawv ntawm txhua feem yuav tsum tsawg li tsawg tau, feem ntau tsis tshaj 300mpa.s;
(3) lub isocyanate tivthaiv feem ntau yog cov mdi-based prepolymer;
(4) txhua feem muaj kev sib haum xeeb zoo, thiab qhov sib xyaw qhov sib xyaw ntawm qhov sib npaug ntawm cov cheem fab yuav tsum yog 1: 1, feem ntau tsis tshaj 3: 1;
(5) ceev ceev yuav tsum ceev npaum li sai tau, tab sis lub sij hawm tuaj yeem yuav tsum ntau dua 5s, thiaj li tsis muab cov gel thaum muaj kev cuam tshuam. Feem ntau, lub sij hawm tuaj yeem yuav tsum yog nyob rau hauv 60s, thaum lub sij hawm tuaj yeem yuav tsum yog luv thaum lub caij foob kom tsis txhob hle qhov quav;
(6) tshwjxeeb tsim tshwjxeeb rau kev siv tshuaj khib nyiab txuam txau khoom siv.
