Polyurea yog ib qho khoom elastomeric ua los ntawm cov tshuaj tiv thaiv ntawm cov amino compound tivthaiv nrog lub isocyanate tivthaiv. Polyurea mas feem ntau tiv thaiv kev txhawj xeeb, dej thiab puas ntsoog. Polyurea tuaj yeem ua tus cwj pwm hauv cov khoom siv hluav taws xob thiab polyurea. Kuv tau kawm txog txoj hauv kev polyurea. Cia peb ua raws li Xiaobian kom paub tias qhov twg yog txoj cai dawb huv. Yuav ua li cas yog polyurea pure generated?
Cov khoom ntawm lub siab dawb polyurea thiab semi-polyurea yog txawv heev. Pure polyurea yog cov khoom siv polyurea uas yog tsim los ntawm cov tshuaj tiv thaiv instantaneous ntawm cov amino compound thiab ib qho tshuaj tiv thaiv isocyanate tsis muaj ib qho catalyst hauv chav sov los yog hauv qab. Pure polyurea cov khoom muaj tshwj xeeb cov khoom tsis tam sim no nyob rau hauv cov khoom siv hluav taws xob polymeric. Pure polyurea cov ntaub ntawv kuj muaj cov cuab yeej ntawm tsis muaj ib qho catalyst, ntshiab thiaj li polyurea muaj ntau tseem ceeb kev laus ua hauj lwm tshaj li ntawm semipolyurea.
