Daim ntawv teev cov khoom siv raw uas xav tau rau kev tsim cov yeeb nkab PVC
| Raw Khoom Qeb | Hom / Piv txwv | Lub luag haujlwm tseem ceeb |
| Cov ntaub ntawv tseem ceeb | PVC cob (xws li SG-5) | Cov khoom siv hauv paus tseem ceeb uas ua rau lub cev tseem ceeb ntawm cov yeeb nkab |
| stabilizer | Thaum tshav kub kub stabilizers (hlau soaps / organic tin compounds), lub teeb stabilizers, antioxidants | Tiv thaiv PVC los ntawm decomposing thaum lub sij hawm siab -kub ua, txhim kho huab cua tsis kam, thiab ncua kev pab cuam lub neej |
| roj nplua nyeem | Cov roj nplua nyeem sab nraud (piv txwv li, paraffin wax / PE wax), cov roj nplua nyeem sab hauv (xws li stearic acid / monoglycerides) | Txo kev sib txhuam ntawm cov khoom siv thiab cov khoom siv, txhim kho cov khoom ntws, thiab tsim kom muaj qhov ci ntsa iab ntawm cov yeeb nkab |
| Filler | calcium carbonate, talc, thiab lwm yam. | Txo cov nqi thiab txhim kho qee yam khoom ntawm lub cev |
| Hloov kho | Cov kev hloov pauv cuam tshuam (piv txwv li, CPE / MBS), kev pab ua haujlwm (xws li, ACR) | Txhim kho qhov cuam tshuam ntawm cov khoom siv yeeb nkab, txhim kho nws cov txheej txheem, thiab tiv thaiv cov tawg tawg. |
| Xim xim | Pigments, xim masterbatch | Cov pigments no tsis tsuas yog muab cov xim tshwj xeeb rau cov khoom siv yeeb nkab tab sis kuj muab cov huab cua tiv thaiv thiab tiv thaiv -cov khoom qub (xws li titanium dioxide, carbon dub). |
| Lwm yam additives | Plasticizers, nplaim retardants, foaming agents, antistatic agents, thiab lwm yam. | Txhawm rau ua kom tau raws li cov kev xav tau tshwj xeeb, xws li kev xav tau cov yas yas hauv cov raj hloov tau yooj yim |
Lus Cim Tshwj Xeeb: Rigid Tubing vs. Flexible Tubing
Rigid PVC kav (xws li cov kav dej thiab cov kav dej): Feem ntau, tsis muaj cov yas ntxiv. Yog tias cov plasticizers ntxiv, lawv txo cov yeeb nkab rigidity.
Flexible PVC kav: Ib qho loj ntawm cov yas yas (xws li DOP) yuav tsum tau ntxiv los ua kom cov khoom hloov tau.
