Daim ntawv thov
PVC resin yog ib qho nruab nrab molecular hnyav ncua kev kawm hom PVC resin haum rau cov khoom siv extrusion nruj.Nws yog tshwj xeeb tshaj yog pom zoo rau cov kav dej thiab cov kav dej,nruj profiles, daim ntawv nruj, inplasticisisail zaj duab xis thiab lwm yam ntawm qhov nruab nrab molecular hnyav nrog rau kev ua kom yooj yim rau cov khoom siv tau yooj yim, tseem tswj cov khoom siv tau yooj yim.Nws cov khoom siv hluav taws xob sib npaug tsis pub zoo li qub los txhim kho thiab txo lub sijhawm ntws.Nyob rau tib lub sij hawm cov resin muaj yam tsawg kawg nkaus volatiles.Qhov nqaim ntau ntawm porosity ua rau nws yooj yim los tuav ib qho chaw sib xyaw ua ke ntawm cov roj nplua nyeem tas li.Uniform coarseness ntawm cov nplej ntawm cov resin no ua rau yooj yim tuav, yam tsawg kawg nkaus yuav tsum tau lubricant thiab ntau yam fluxing nyob rau hauv lub extruder.
