Txhua yam khoom ntawm Polystyrene

Polystyrene molecular nyhav no feem ntau yog 5 ~ 20, siab molecular phaus, ces tej yam teeb meem ua yuav tshwm sim. Txhua yam khoom uas PS, thiab kev ua kub, mob heev, modulus elasticity, tensile zog npaum cas, tej yam yuav ua tau, tsis, thiab tus nqi elongation. PS pob tshab, lub teeb kis tus nqi ntawm 88 ~ 92%, tom qab acrylic polymer, refractive Performance index 1.59 ~ 1.60. Nws yuav siv li hais kho qhov muag, tab sis tom qab nphav raug tshav, nws daj thiab turbidity. PS muaj cov loj disadvantages muaj embrittlement thiab tsis kub-kuj. Yog hloov PS, xws li roj hmab-hloov siab tej yam PS (lub DUAV), MMA--butadiene-styrene (MBS), ib (acrylonitrile) (butadiene) b s, nyob hauv txoj kev lag luam tus tseem lug siv yog ABS yas. Yav tom ntej, check rwb thaiv tsev: extrusion, thermal conductivity rau 0.028w / MK, muaj tus yam ntxwv kuj kub siab thiab tsis tawm expansion. Cov thermal conductivity tseem qis tshaj lwm rwb thaiv tsev ntawv, xws li: EPS thermal insulating tshuaj khib, pawg thawj coj saib MAAs, ua npuas ncauj polyurethane, perlite, thiab hais txog. Thiab vim tias cov khoom muaj ruaj khov tshuaj lom neeg thiab kev tsa ntawm benzene, nco ntsoov tias cov rwb thaiv tsev thermal khoom ntawm ib tug kav thiab ruaj khov.
