CPVC kav dej qhov tshwj xeeb

Raws li yam tshiab ntawm cov raj xa dej, CPVC cov yeeb nkab muaj kev txhim kho corrosion zoo heev. Xyoo tsis ntev los no, nws tau siv dav hauv hlau, hlau, roj av, tshuaj lom neeg, chiv, xim, tshuaj, hluav taws xob, kev tiv thaiv ib puag ncig thiab kev lag luam kho dej phwj tuaj. Nws yog cov khoom siv hlau tiv thaiv kab mob Qhov hloov pauv zoo tshaj plaws.

Vim yog qhov nce ntawm cov ntsiab lus tshuaj hauv cov khoom, qhov tsis sib xws ntawm CPVC cov qauv hauv cov qauv nce (qhov crystallinity tsawg dua thiab cov polarity ntawm cov saw molecular nce), uas ua rau nws cov thermal deformation kub.

Kev siv qhov kub ntawm CPVC cov khoom tuaj yeem ncav cuag txog 93-100 ℃, uas yog 30-40 ℃ siab dua li PVC. Nyob rau tib lub sijhawm, nws txhim kho tshuaj lom neeg tsis kam thiab tiv taus corrosion ntawm PVC. Nws tuaj yeem tiv taus cov kua qaub, muaj zog alkalis, ntsev, fatty acid ntsev, oxidants thiab halogens. Thiab lwm yam tshuaj lom neeg xeb.

Ib qho ntxiv, lub zog tensile thiab khoov zog ntawm CPVC kuj tseem txhim kho piv nrog PVC. Piv nrog rau lwm cov ntaub ntawv polymer, CPVC muaj kev tiv thaiv kev laus zoo, tiv taus xeb thiab nplaim hluav taws kub nyhiab. CPVC cov khoom siv raw muaj cov ntsiab lus chlorine ntawm 63-74%, uas yog siab dua PVC (cov ntsiab lus chlorine 56-59%). Kev ua viscosity tsawg kawg yog ob zaug siab dua, thiab qhov ceev ntawm CPVC (nruab nrab ntawm 1450-1650Kg/m) ntau dua li ntawm PVC. Cov ntaub ntawv saum toj no txiav txim siab tias CPVC nyuaj rau txheej txheem ntau dua li PVC.
