Faahfaahinta Alaabta
Xasilinta cusbada rasaasta ee looxa PVC WPC SPC waa boodh cad ama wax yar oo huruud ah.Ku milmay toluene, ethanol iyo dareerayaasha kale, ee aan lagu milmin biyaha, way qudhmi doonaan haddii ay jirto asiidh xooggan.

Sida Loo Doorto Dejinta Kulaylka PVC ee Naqshadeynta Caagagga
Sababta ugu weyn ee loogu daro qaboojiyaha kulaylka PVC ee naqshadaynta caagga ah ayaa ah in ay qabsan karto HCL autocatalytic oo ay sii daysay resin PVC, taas oo lagu muujin karo ku darista qaab dhismeedka polyene-ka ee aan xasilloonayn ee ay soo saarto resin PVC, si looga hortago ama loo yareeyo burburka Xabagta PVC.Si si fiican loo xalliyo farsamaynta PVC waxay ku dhici kartaa noocyo kala duwan oo ifafaale aan loo baahnayn.
Xasijiye kuleyliyaha PVC ee lagu doortay qaabka guud waa in loo tixgeliyo si waafaqsan sifooyinka, shaqooyinka iyo shuruudaha alaabta.Tusaale ahaan, xasiliyaha isku dhafka cusbada rasaasta oo inta badan loo isticmaalo alaabada adag waxay leedahay sifooyin kuleyliyaha wanaagsan, waxqabadka korantada oo aad u wanaagsan iyo qiimo jaban.Khasaarooyinku waa sun, fududahay in la wasakheeyo alaabta, waxay soo saari kartaa oo kaliya alaab aan muuqan.
Calcium zinc composite stabilizer waxaa loo isticmaali karaa sida xasiliye aan sun ahayn, oo loo isticmaalo baakadaha cuntada iyo qalabka caafimaadka, baakadaha daroogada, laakiin xasiloonideedu waa mid aad u hooseysa, qiyaasta xasilinta calcium marka daahfurnaanta liidata, fudud in lagu buufiyo dhaxan.Calcium iyo zinc isku-darka xasiliya guud ahaan waxay isticmaalaan polyol iyo antioxidant si ay u horumariyaan waxqabadkeeda.
Labada nooc ee kor ku xusan ee qaboojiyeyaasha kuleylka ee PVC ayaa si caadi ah loo isticmaalaa hadda, laakiin codsiga dhabta ah kuma koobna kan, laakiin sidoo kale waxaa ku jira xasiliyeyaasha kulaylka daasadaha organic, stabilizers epoxy, stabilizers Earth nadir iyo stabilizers hydrotalcite.
