Pentane yog tus neeg sawv cev nthuav dav tshaj plaws hauv EPS ntau lawm.Pentane cov ntsiab lus ntau npaum li cas yog tsim nyog rau Expanded polystyrene.
EPS pentane cov ntsiab lus tsis yog qhov siab dua qhov zoo dua.
Standard: 4.8-7 feem pua ( Tsawg dua los yog sib npaug li 6.8 feem pua )
Feem ntau ib txwm muaj li ntawm 5 feem pua
Yog tias muaj ntau tus neeg ua npuas ncauj pentane hauv qhov sib tov: Tom qab siv EPS, taum yuav tawg tsis sib xws, distort, thiab tawg.
Yog hais tias lub pentane concentration ntawm cov foaming tus neeg saib xyuas yog tsawg dhau lawm, nws yuav ua rau ib tug qis expanding multiplier, ib tug ntev lub sij hawm cua sov xav tau, tsis zoo bonding ntawm EPS hlaws dai thaum molding, yooj yim shrinkage ntawm kawg EPS ua npuas ncauj khoom, thiab nyuaj melting ntawm lub EPS taum, ntawm lwm yam teeb meem.
