Feature ntawm PVC

PVC: Nws yog ib qho ntawm cov khoom yas uas muaj cov khoom loj tshaj plaws nyob hauv lub ntiaj teb. Nws yog pheej yig thiab dav siv. Cov polyvinyl chloride resin yog dawb los yog lub teeb daj hmoov. Raws li kev siv sib txawv, cov khoom siv sib txawv tuaj yeem muab ntxiv, thiab PVC yas tuaj yeem pom cov khoom sib txawv ntawm lub cev thiab cov khoom siv kho tshuab. Ntxiv qhov tsim nyog ntawm cov yas yas rau polyvinyl chloride resin tuaj yeem ua rau ntau yam khoom tawv, muag muag thiab pob tshab. Qhov ceev ntawm ntshiab PVC yog 1.4g / cm3, thiab qhov ceev ntawm PVC yas qhov chaw nrog plasticizers thiab fillers feem ntau yog 1.15-200g/cm3. Rigid PVC muaj qhov zoo tensile, khoov, compressive thiab cuam tshuam cov khoom, thiab tuaj yeem siv ib leeg ua cov khoom siv. Lub softness, elongation ntawm so, thiab txias tsis kam ntawm mos PVC yuav nce, tab sis lub brittleness, hardness, thiab tensile zog yuav txo. Polyvinyl chloride muaj cov khoom siv hluav taws xob zoo, tuaj yeem siv los ua cov khoom siv hluav taws xob tsawg tsawg, thiab nws cov tshuaj lom neeg ruaj khov kuj zoo. Vim tias qhov tsis zoo thermal stability ntawm polyvinyl chloride, cua sov mus sij hawm ntev yuav ua rau decomposition, tso HCL roj, thiab ua rau polyvinyl chloride discolor, yog li nws daim ntawv thov ntau nqaim, thiab kev khiav hauj lwm kub yog feem ntau ntawm -15 degrees mus rau 55. qib.
