Umahluko phakathi kodonga oluphindwe kabini lwe-HDPE kunye ne-PVC kabini eludongeni
Nangona i-HDPE i-double-bellows ye-HDPE kunye ne-PVC i-double-bellows ebizwa ngokuba yi-double-bellows ebizwa ngokuba yi-double-bellows, kodwa ukongeza kwinkangeleko efana nencinci, kwiindawo ezininzi zahluke kakhulu, ukuba awukholelwa, jonga nje uthotho oluncinci ukuze udwelise ezi zahlukeneyo.I. UPVC yenza...Funda ngokugqithisileyo -
inkqubo yemveliso ye EPE
I-EPE (ExpandableClimatic Tests) yipolyethylene esuswayo, ekwaziwa njengoboya beperile.Isakhiwo seseli esivaliweyo esingenasiphambano, yimveliso ephezulu ye-foam polyethylene eveliswa yi-extrusion ye-low density polyethylene (LDPE) njengeyona nto iphambili ekrwada.I-EPE ine-elasticity ephezulu kunye nenkangeleko emhlophe.Yiba...Funda ngokugqithisileyo -
Inkqubo yokuvelisa i-LDPE
Uxinaniso oluphantsi lwe-polyethylene (LDPE) yi-ethylene eyenziwe nge-polymerized njenge-polymerization monoma, i-peroxide njenge-initiator, i-resin ye-thermoplastic efunyenwe nge-free radical polymerization reaction, ubunzima be-molecular ngokubanzi yi-100000 ~ 500000, ubuninzi be-0.91 ~ 0.93g / cm3, yi-0.91 ~ 0.93g / cm3, olona didi lulula lwe...Funda ngokugqithisileyo -
