Cov txheej txheem tiv thaiv dej polyurethane thiab cov txheej txheem tiv thaiv dej acrylic yog ob hom txheej txheem tiv thaiv dej uas siv ntau. Lawv muaj qhov sib txawv tseem ceeb hauv cov khoom siv, cov yam ntxwv ntawm kev tsim kho thiab cov teb siv tau.
Ua ntej, hais txog cov khoom siv sib xyaw, polyurethane txheej tiv thaiv dej feem ntau yog ua los ntawm polyurethane resin, cov kuab tshuaj thiab cov khoom ntxiv, thiab muaj qhov elasticity siab thiab tiv taus huab cua. Acrylic txheej tiv thaiv dej yog ua los ntawm acrylic resin, cov khoom sau thiab cov khoom ntxiv. Nws yog tus cwj pwm los ntawm kev ziab sai thiab kev ua yeeb yaj kiab zoo.
Qhov thib ob, hais txog cov yam ntxwv ntawm kev tsim kho, cov txheej txheem tiv thaiv dej polyurethane feem ntau xav tau qib kev txawj ntse siab dua thaum lub sijhawm tsim kho, yuav tsum tau tsim kho hauv ib puag ncig zoo dua, thiab muaj cov kev xav tau siab dua rau kev kho qhov chaw ntawm lub hauv paus. Cov txheej txheem tiv thaiv dej acrylic yooj yim rau kev tsim kho thiab tuaj yeem tsim kho hauv qab cov xwm txheej ib txwm muaj, thiab muaj cov kev xav tau qis dua ntawm qhov chaw ntawm lub hauv paus.
Tsis tas li ntawd xwb, hais txog cov teb uas siv tau, vim tias polyurethane txheej tiv thaiv dej muaj qhov ywj siab thiab tiv taus huab cua, nws tsim nyog rau cov chaw uas xav tau kev tiv thaiv mus sij hawm ntev thiab raug kev ntxhov siab loj, xws li ru tsev, qab nthab, thiab lwm yam. Acrylic txheej tiv thaiv dej yog tsim rau kev tiv thaiv dej hauv tsev dav dav thiab tuaj yeem tsim tau sai. Nws tsim nyog rau qee lub sijhawm uas lub sijhawm tsim kho luv luv thiab xav tau kev pab sai.
Muaj qhov sib txawv ntawm cov txheej txheem tiv thaiv dej polyurethane thiab cov txheej txheem tiv thaiv dej acrylic hauv cov ntsiab lus ntawm cov khoom siv, cov yam ntxwv ntawm kev tsim kho thiab cov teb siv tau. Ua ntej kev tsim kho, yuav tsum xaiv cov txheej txheem tiv thaiv dej tsim nyog raws li qhov xav tau tshwj xeeb ntawm cov haujlwm.
