PU (Polyurethane) thiab tsiaj (polyethylene terephthalate) foams nthuav qhia qhov sib txawv ntawm ntau yam:
Cov qauv tshuaj thiab muaj pes tsawg leeg
PU ua npuas ncauj yog cov khoom siv polymer los ntawm cov tshuaj tiv thaiv ntawm {}}} nws cov khoom ua npuas dej muaj ntau yam ua rau muaj kev ua kom muaj ntau yam Polyethylene TereFthalate, uas tau txais ntawm cov Esterification thiab Polycondensation ntawm Terephrene Gycol {}} Ua ib qho kev ua npuas dej tsis tu ncua, kom muaj kev ruaj khov molecat .
Cov Khoom Siv Lub Cev
Ceev thiab hardness: PU ua npuas muaj ntau yam ntom nti, ua rau cov ntaub ntawv me me rau hauv cov sofas, thiab siv tau los ntawm cov rooj txaj muag, thiab muaj peev xwm siv rau hauv Sofas, thiab lwm yam kev txaj muag, thiab lwm yam Cushioning Cov khoom lag luam . tawv tawv, uas yog qhov ua rau lub zog ua npuas dej, muab kev txhim kho kom zoo nkauj, muab cov qauv hluav taws xob tsis zoo, muab cov qauv sib txuas tau zoo, muab cov qauv hluav taws xob tsawg, muab cov qauv sib txuas tau zoo, muab cov qauv sib xyaw ua ke, muab cov qauv sib txuas tau zoo, muab cov qauv sib txuas tau zoo, muab cov qauv sib txuas tau zoo, muab kev txhim khu kev qha cov qauv zoo nkauj, muab kev txhim khu kev qha cov qauv zoo nkauj, muab kev txhim khu kev qha cov qauv, muab kev txhim khu kev qha cov qauv, muab kev txhim khu kev qha cov qauv, muab kev txhim khu kev qha cov qauv, muab kev txhim khu Qhov .
Thermal Insulation and Flame Retardancy:PU foam, especially the rigid variety, demonstrates excellent thermal insulation properties due to its low thermal conductivity, making it a popular choice for building and industrial insulation. However, conventional PU foam is flammable and requires the addition of flame retardants to enhance its fire resistance. PET foam also possesses certain thermal insulation capabilities thiab inherently cov khoom pov thawj zoo nplaim retardancy.}}}}}}}}} Tsis muaj cov tub rog tawg thaum hlawv, txhim kho tag nrho kev nyab xeeb.
Tshuaj lom neeg thiab huab cua tiv thaiv: PU ua npuas ncauj qhia cov roj ua kom zoo, thiab lwm yam av noo} ntev thiab lwm yam av noo} alkalis, thiab cov kuab tshuaj organic . Cov huab cua zoo tshaj li nws tau ruaj khov ua tau zoo tshaj plaws huab cua huab cua {}}
Tshuab
PU ua npuas ncauj yog cov ua npuas dej {}}}}}}}}}}}}} {}}}}}} {}}}}} {}}}}}}}} compression molding . Tus tsiaj raw khoom yog thawj zaug ua npuas ncauj thiab tom qab ntawd cov txheej txheem no xav tau tswj qhov kub thiab kub}
Daim Ntawv Thov
PU npuas ncauj nyiam cov kev siv hluav taws xob dav dav} Nrog txoj hlua khi kom tau rau cov khoom siv zog, qhov chaw nyob sab hauv, thiab cov nplaim hluav taws xob sib xyaw ua ke thaum ua kom muaj kev ntseeg siab thiab kev nyab xeeb.
