Qhov sib txawv ntawm PPR thiab PVC kav
Jul 06, 2022
Cov ntaub ntawv sib txawv: PVC yog ua los ntawm polyvinyl chloride, thiab PPR yog ua los ntawm random copolymer polypropylene.
- Xim txawv: PPR yeeb nkab toughness yog zoo dua li PVC, thiab zoo zoo thiab kaj xim, lwm tus muaj lub teeb milky daj, thiab tsis zoo xim thiab chaos. Cov yeeb nkab PVC ua los ntawm cov yas extrusion kab yog milky dawb, cov khoom yog ib qho nyuaj tshaj li PPR, thiab ntu ntu tsis ci, tab sis nws sab nrauv yog ci iab.
- Qhov txawv ntawm phab ntsa thickness: Qhov diameters ntawm PPR thiab PVC kav yog tib yam. Qhov sib txawv loj tshaj plaws yog nyob rau hauv phab ntsa thickness, PPR yeeb nkab thickness, thiab PVC yeeb nkab phab ntsa thickness. Ob leeg PPR yeeb nkab thiab PVC yeeb nkab muaj cov lus ntawm lawv. Koj tuaj yeem nkag siab ntawm ib nrais muag, thiab qhov toughness ntawm PPR yeeb nkab yog qhov zoo. Nyob rau hauv tib txoj kab uas hla, cov phab ntsa ntawm cov yeeb nkab PPR feem ntau yog tuab.
- Tus nqi: Tus nqi sib txawv, tus nqi ntawm PVC yog qis dua PPR, tus nqi qis yog qhov zoo ntawm cov khoom siv PVC.
- PPR yeeb nkab muaj qhov zoo ntawm lub teeb yuag, zoo tiv thaiv corrosion, tsis muaj fouling, thiab lub neej ua haujlwm ntev.
- Acidity: Tsis tas li ntawd, PPR kav dej muaj kev nyab xeeb thiab tsis muaj tshuaj lom. Nws yog siv rau hauv cov kav dej kub thiab dej txias thiab hauv cov dej haus. Cov nplaum siv los koom nrog khoov, Tees, thiab cov kav dej hauv PVC yog cov ntxhiab tsw heev thiab yuav ua rau acidic rau qee tus tswv tsev.
