Cov txheej txheem ntau lawm
PE tarpaulin raw cov ntaub ntawv feem ntau xa mus rau cov xim dawb, uas yog PE ntaub npog nrog PE zaj duab xis ntawm ob sab, thiab polypropylene kuj tseem muaj txiaj ntsig. Cov txheej txheem tsim khoom yog PE daim duab-ncig cov ntaub npuag-ob txheej txheej. Hom ntaub thaiv npog no muaj cov dej tsis zoo ua haujlwm. Feem ntau, tom qab siv nws ib zaug ntawm lub tsheb, tsis muaj kev lees paub tias nws yuav tsis xau, tab sis nws qhov hnyav yog lub teeb thiab huv.
PVC tarpaulin yog polyester polyester muab tshuaj txhuam uas tsis pleev xim rau ob sab nrog yas. Vim yog txheej txheem dipping, muaj PVC hauv qhov sib txawv ntawm cov ntaub yas yas, uas muaj cov dej tsis zoo ua tau zoo. Nws cov txheej txheem tsim khoom: polyester ntaub-dipping-kom qhuav-calendering-txias -Rewinding, tam sim no lub carport saum lub tsheb, lub Hoobkas npog thiab cov khoom tsis muaj dej, cov chaw nres tsheb khoom thiab lwm yam khoom tiv thaiv los nag yog txhua yam ua los ntawm PVC-txheej ntaub.
Daim ntaub Oxford yog txheej ib sab ntawm PE lossis PP ntawm daim ntaub polyester lossis ntaub ntaub nylon (tus nqi siab feem ntau tsis siv), feem ntau hloov cov ntaub ntawv, nws cov txheej txheem tsim khoom yog polyester ntaub-txheej-embossing-txias-cua. Kev ua dej tsis zoo ntawm daim ntaub Oxford tsis zoo heev, thiab nws tsuas yog siv rau lub hnab. Vim tias nws muaj tshuaj lom nyob ruaj khov, nws tuaj yeem siv los ua cov tshuaj tiv thaiv xeb, cov yeeb nkab txuas, cov raj xa dej, cov twj centrifugal, thiab tshuab cua, thiab lwm yam. , cov laug cam rau cov tsev, cov qhov rooj thiab qhov rai, kho kom zoo nkauj phab ntsa, thiab lwm yam khoom siv tsim kho. Vim nws qhov kev tiv thaiv hluav taws xob zoo tshaj plaws, nws tuaj yeem siv los tsim cov ntsaws, qhov (socket), hloov pauv, thiab cov xov hluav taws xob hauv kev lag luam hluav taws xob thiab hluav taws xob.
Polyvinyl chloride tau muab coj los ua ke los ntawm acetylene roj thiab hydrogen chloride los ua cov yas chloride thiab tom qab ntawd ua cov polymerized. Muaj cov cuab yeej muaj zog ntau dua thiab zoo dua corrosion kuj. Nws tuaj yeem siv los ua cov pa nkev pov tseg thiab tshem tawm cov yees pov tseg thiab cov pa roj ua kua xa cov kav dej hauv tshuaj lom neeg, textile, thiab lwm yam lag luam, thiab tseem tuaj yeem hloov lwm yam khoom siv tiv taus xeb kom ua rau tso tso tsheb hlau luam, centrifugal twj, lub tshuab ua pa, thiab pob qij txha. Thaum cov yas yas ntxiv rau hauv 30% mus rau 40%, cov polyvinyl chloride muag muag tau tsim, uas muaj qhov siab siab, cov khoom muag muag, thiab muaj kev tiv thaiv zoo corrosion thiab hluav taws xob rwb thaiv tsev. Nws yog feem ntau ua rau hauv cov yeeb yaj kiab thiab siv rau kev ntim khoom lag luam, cov yub ua liaj ua teb thiab cov tsho ntev niaj hnub, cov ntaub ntaub, thiab lwm yam, kuj tseem tuaj yeem siv los ua kua qaub thiab alkali tiv thaiv hoses, kab thaiv kab hlau, txheej rwb thaiv tsev, thiab lwm yam.
Muaj ob txoj hauv kev tsim khoom rau cov ntaub thaiv npog:
Ib qho yog kev siv lub tshuab kab rov tav, uas yog hom hnyav-lub tog raj kheej loj. Tom qab muab cov ntaub xaum tso rau hauv cov khoom, nws tau muab tso rau ntawm txoj siv tawv, thiab hauv qab ntawm lub tog raj kheej hnyav uas hnyav tau nias thiab ua kom tiaj, thiab tom qab ntawd rub lub tshuab ziab kom qhuav. Tom qab ntawd txiav, faib, thiab ntim.
Ib qho yog lub tshuab ntsug tsim, cov ntaub yog ncaj rau hauv lub thawv raw khoom thiab rub tawm. Cov khoom siv khov ntawm cov ntaub so ntswg yog cov khoom siv PVC-purity siab, thiab tom qab ntawd ob sab yog ncaj los ntawm lub tshuab riam thiab txhuam nrog rab riam. Tom qab ntawd, nws tau qhuav hauv lub tshuab ziab khaub ncaws, txiav, faib ua cov voj, thiab ntim rau hauv.
Muaj ob hom tshuab ziab khaub ncaws:
Ib qho yog hlawv nrog hluav taws xob,
Ib qho yog siv lub rhaub dej kub.
PVC-txheej cov ntaub thaiv npog uas tsim los ntawm lub tshuab kab rov tav yog pheej yig dua li PVC-txheej cov ntaub thaiv npog uas ua los ntawm lub tshuab ntsug. Qhov laj thawj yog tias cov khoom siv raw ntawm lub tshuab kab rov tav qis dua li ntawm lub tshuab ntsug. Kev tsim cov tshuab kab rov tav qis dua. Txhua yam khoom siv roj hmab tuaj yeem tso rau thiab nias, tab sis kev tsim tshuab ntsug tsis tuaj yeem ua tau. Cov tseev kom muaj rau cov khoom siv raw yog siab, thiab yuav tsum tau ua kom huv ntawm cov ntaub ntawv raw. PVC tarpaulin tsim los ntawm lub tshuab ntsug feem ntau kim dua me ntsis, thiab kev ua kom huv ntawm cov khoom siv tarpaulin kuj tseem siab.
Hauv cov ntaub thaiv dej tsis zoo, cov yas txheej txheej muaj cov dej tsis ua haujlwm zoo. Nws yog tsim los ntawm cov ntaub fiber ntau thiab cov khoom siv tshuaj lom neeg los ntawm cov txheej txheem tsim khoom xws li dipping, txheej, scraping, kom qhuav, thiab txias. Cov txheej txheem txheej txheem txheej txheej ntawm txheej txheej txheej txheej txheej txheej yog daim ntaub uas tsis muaj ntaub qhwv los ntawm lub zog polyester muaj zog, cov hmoov zoo zoo, cov yas yas, tshuaj ruaj khov, cov tshuaj calcium uas tsim nyog, thiab me me ntawm lwm cov khoom siv tshuaj lom neeg. Feem ntau cov cheeb tsam nyob rau sab qaum teb hu ua daim ntaub toch, thiab qee thaj chaw nyob rau sab qab teb tseem hu ua daim ntaub. Muaj ntau cov ntaub ntawv rau cov ntaub thaiv tsis tau dej, xws li cov ntaub npog PVC thiab cov ntaub nylon tsis muaj dej. Lub hauv paus tseem ceeb ntawm PVC-txheej ntaub yog polyvinyl chloride. Hauv kev tsim cov txheej txheem ntawm PVC tarpaulin, qee cov khoom pabcuam xws li cov yas yas thiab cov tshuaj ntxiv tau ntxiv los txhim kho nws cov cua sov tiv taus, tawv thiab ductility. Qhov saum npoo yog coated nrog muab tshuaj txhuam. Tus neeg sawv cev ua kom nrawm, tiv thaiv tus neeg sawv cev tiv thaiv kab mob, tiv thaiv kev laus tus neeg sawv cev, tus neeg sawv cev, thiab lwm yam tshuaj ntxiv, nrog tsis kub hnyiab, muaj zog siab, tiv taus huab cua, thiab ruaj khov geometric zoo, tab sis kuj tsis muaj dej, tiv thaiv kab mob, hnav-tiv taus, Ua haujlwm ntev, txias tsis kam, kev laus tiv taus, thiab lwm yam kev ua haujlwm ntuj. Cov ntaub nylon tsis muaj dej muaj qhov ua tau zoo tiv thaiv kab mob, nplaim hluav taws tsis zoo yog 100% tsis muaj dej, thiab tsis muaj dej tsis sib xws piv rau lwm cov ntaub thaiv npog, nrog qhov ua tau zoo tsis tshua muaj zog, muaj zog siab, muaj zog tensile zog, thiab yog qhov sib dua. Txoj hauv kev ua haujlwm tseem ceeb yog kub kub ua kom sov.
