Muaj qhov sib txawv ntawm cov ntaub ntawv, txheej txheem, thiab kev ua tau zoo ntawm PEF rwb thaiv tsev kav thiab feem ntau hu ua PE rwb thaiv tsev lub tes tsho (tiag tiag roj hmab thiab cov ntaub ntawv yas ua los ntawm kev sib xyaw ntawm nitrile roj hmab thiab polyvinyl chloride). PEF siv polyethylene ua cov khoom siv hauv paus thiab tuaj yeem ua rau B1 lossis B2 qib nplaim hluav taws- cov khoom lag luam retardant los ntawm cov pwm ua npuas thib ob. Nws muaj ntau yam xim thiab yog tus nqi qis dua -. Nws yog qhov tsim nyog rau cov dej noo- cov ntaub ntawv pov thawj thiab cov rwb thaiv tsev txias uas muaj cov kev cai dav dav ntawm tus nqi thiab daim ntawv lo. PE rwb thaiv tsev casing (cov roj hmab thiab yas) siv cov txheej txheem nruam foaming, thiab cov foaming ratio tuaj yeem hloov kho tau yooj yim. Cov khoom nws tus kheej tsuas tuaj yeem ncav cuag B1 qib nplaim hluav taws kub thiab muaj ib qho xim (feem ntau tsuas yog dub). Txawm li cas los xij, vim yog cov khoom siv raw thiab cov txheej txheem ntau dua, tus nqi tag nrho yog siab dua li ntawm PEF. Zuag qhia tag nrho, PEF muaj cov nqi ua tau zoo tshaj plaws thiab kev xaiv xim nplua nuj, thiab tsim nyog rau kev rwb thaiv tsev ntawm cov pa cua - cua txias ducts thiab khoom siv. Txawm hais tias PE rwb thaiv tsev casing (cov roj hmab thiab yas) kim dua thiab muaj tsawg dua cov xim xaiv, nws muaj qhov zoo ntawm cov pa ducts thiab cov kav dej txias txias uas yuav tsum tau muaj kev tiv thaiv hluav taws ntau dua thiab ntev - lub sij hawm ua haujlwm ntev vim nws qhov kev ua tau zoo dua, kev laus ua hauj lwm, thiab ruaj khov B1- qib nplaim hluav taws kub. Ob leeg muaj lawv tus kheej qhov zoo, thiab qhov kev xaiv tiag tiag yuav tsum tau ntsuas raws li qhov project pob nyiaj siv, qib tiv thaiv hluav taws, thiab kev tsim kho.
