Taw qhia peb qhov kev tsim kho tshiab tshaj plaws hauv kev lag luam PVC: kev ua tau zoo siabcov roj hmab polyethylene.Ua ib qho khoom siv ntxiv uas siv tau ntau yam thiab tseem ceeb, cov polyethylene waxes tab tom hloov pauv txoj kev uas cov tuam ntxhab tsim cov qauv PVC, txhim kho qhov zoo thiab kev ua haujlwm ntawm lawv cov khoom.
Polyethylene quav ciabyog ib qho polymer uas tsis muaj molecular hnyav uas muab ntau yam txiaj ntsig thaum ntxiv rau PVC daim ntawv thov. Nws cov yam ntxwv tshwj xeeb ua rau nws zoo tagnrho rau kev txhim kho cov txheej txheem thiab kev ua tau zoo ntawm PVC cov ntaub ntawv. Polyethylene wax ua haujlwm ua lub roj nplua nyeem, txo qhov kev sib txhuam thaum lub sijhawm extrusion thiab molding, ua rau cov khoom lag luam du thiab zoo dua qhov chaw tiav. Qhov no tsis yog tsuas yog txhim kho qhov zoo nkauj ntawm cov khoom kawg, tab sis kuj txhim kho nws cov durability thiab longevity.
In ntxiv rau nws cov khoom lubricating,Cov tshuaj polyethylene ua haujlwm ua cov tshuaj dispersant, ua kom ntseeg tau tias cov xim thiab lwm yam khoom ntxiv tau faib sib npaug thoob plaws hauv PVC matrix. Qhov kev sib xyaw ua ke no tsim cov xim ci ntsa iab thiab kev ua haujlwm zoo ib yam, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov chaw tsim khoom uas tab tom nrhiav cov txiaj ntsig zoo. Tsis tas li ntawd, qhov sib xws ntawm cov tshuaj nplaum nrog ntau yam PVC formulations ua rau kev sib koom ua ke tsis muaj teeb meem, ua rau nws yooj yim ntxiv rau cov txheej txheem tsim khoom uas twb muaj lawm.
Kev siv cov polyethylene waxes hauv kev lag luam PVC kuj txuas ntxiv mus rau kev txhim kho kev ruaj khov thermal thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj thaum lub sijhawm ua. Qhov no yog qhov tseem ceeb rau cov chaw tsim khoom uas tsom mus rau kev tsim cov khoom lag luam PVC ua tau zoo uas tuaj yeem tiv taus qhov chaw ib puag ncig hnyav.
Hauv luv luv, pebcov roj hmab polyethylenetau hloov pauv kev lag luam PVC, txhim kho kev ua haujlwm zoo, txhim kho cov khoom zoo, thiab ua kom muaj kev hloov pauv ntau yam. Txawm koj tsim cov kav dej, cov ntaub ntawv, lossis cov yeeb yaj kiab, peb cov polyethylene waxes tuaj yeem coj koj cov qauv PVC mus rau qib siab tshiab. Paub txog qhov sib txawv hnub no thiab paub txog tag nrho cov peev xwm ntawm koj cov khoom PVC nrog peb cov polyethylene waxes zoo tshaj plaws.
