Nyob rau hauv kev lag luam cable, lub sheath sab nraud ntawm lub cable txiav txim siab txog kev pab cuam lub neej, siv ib puag ncig thiab nqi kev ua haujlwm ntawm cable. PVC thiab pur yog ob feem ntau siv sheathing ntaub ntawv nyob rau hauv cables tam sim no. Daim ntawv no yuav sib piv cov kev ua tau zoo sib txawv thiab daim ntawv thov scenarios ntawm PVC thiab pur cable sheaths nyob rau hauv kom meej, thiab qhia ob peb lub tswv yim txoj kev uas yuav tsum tau ceev nrooj txheeb xyuas yam tsis muaj kev tshaj lij.
PVC kab hlau rhuav
PVC, uas yog polyvinyl chloride, yog cov khoom siv dav siv thoob plaws hauv kev lag luam cable. Cov tsoos PVC sheaths yog tsawg- nqi, yooj yim rau txheej txheem, nrog yooj yim rwb thaiv tsev thiab nplaim taws retardancy, thiab feem ntau yog siv rau cov pa tsau nteg cable khoom. Txawm li cas los xij, cov khoom siv hluav taws xob niaj hnub hloov kho PVC, siab elastic PVC thiab hnav- tiv taus PVC tau zoo heev, uas tuaj yeem ua tau raws li qhov kev siv zog ntawm nruab nrab lub zog.
PUR cable sheath
PUR, los yog polyurethane, yog ib tug siab -cov ntaub ntawv elastomer, uas yog nto moo rau nws super hnav tsis kam, roj tsis kam, siab yooj thiab kub tsis kam. Nws feem ntau yog siv rau hauv cov khoom siv siab xws li kev ua haujlwm hnyav, siab - lub zog rub chains thiab cov neeg hlau. Qhov kev ua tau zoo ntawm PUR muaj zog dua, tab sis tus nqi siab dua, thiab cov nplaim hluav taws xob feem ntau qis dua li cov qauv PVC.
Core sib txawv ntawm PVC thiab PUR cable sheaths
1. Abrasion kuj thiab tsim kua muag kuj tsoos PVC: General abrasion tsis kam, haum rau static fixed thaiv.
Kev ua tau zoo hloov kho PVC: qhov kev tiv thaiv kev puas tsuaj tau zoo heev, uas tuaj yeem tiv nrog qhov nruab nrab zaus bending thiab kev sib txhuam me ntsis, ze rau qib PUR zoo tib yam.
PUR: Kev puas tsuaj rau sab saum toj thiab tsim kua muag, haum rau siab - lub zog rub saw, kev sib txhuam tsis tu ncua thiab cov khoom siv hluav taws xob siab.
2.Flexibility thiab kub tsis kam
PVC: Nws yog feem ntau maj mam thiab muaj qhov zoo toughness, thiab yuav maj mam harden ntawm qhov kub thiab txias.
Kev ua haujlwm siab txias tiv thaiv PVC: nws tuaj yeem hloov kho kom qis dua thiab ua tau raws li qhov chaw nyob sab hauv tsev thiab sab nraum zoov.
PUR: nws tseem mos heev ntawm qhov kub thiab txias thiab tsis yooj yim rau tawg. Nws yog haum rau ntev - siv nyob rau hauv huab cua txias thiab sab nraum zoov.
3.Oil thiab tshuaj tiv thaiv
Standard PVC: roj resistant puag, tsis muaj teeb meem nyob rau hauv luv luv -lub sij hawm sib cuag nrog roj stains.
Roj resistant hloov PVC: nws tuaj yeem tiv nrog cov roj me me ua paug ib puag ncig ntawm cov cuab yeej siv tshuab dav dav thiab cov tshuab engineering.
PUR: zoo heev roj kuj, coolant kuj, tshuaj corrosion kuj, haum rau hnyav roj paug ib puag ncig.
4. nplaim retardant kev ua tau zoo
PVC: cov nplaim hluav taws kub nyhiab, tua tus kheej thaum tua hluav taws, yog qhov kev xaiv tseem ceeb ntawm cov hluav taws xob qis -voltage tswj cables.
PUR: cov qauv ua qauv feem ntau yog nplaim taws retardant thiab xav tau kev hloov kho tshwj xeeb kom ncav cuag cov nplaim hluav taws kub.
5. Huab cua tsis kam thiab UV tsis kam
PVC: qauv zoo tib yam yog ib qho yooj yim rau hnub nyoog sab nraum zoov ntev; Huab cua resistant hloov PVC tuaj yeem ua tau raws li luv luv - siv sab nraum zoov.
PUR: huab cua resistant thiab UV resistant, haum rau ntev -lub sij hawm sab nraum zoov los yog hnyav ib puag ncig.
6. Tus nqi thiab kev ua haujlwm tus nqi piv
PVC: tus nqi qis dua, muaj zog ruaj khov, qis tom qab - muag thiab hloov cov nqi.
Pur: tus nqi yog pom tseeb dua, thiab nws tsim nyog rau cov xwm txheej uas yuav tsum tau siv nrog kev siv siab.
