Ntau tus neeg tsis paub qhov txawv ntawm PE tarpaulin thiab PVC coated tarpaulin. Lus tshaj tawm, PE thiab PVC yog qhov tseeb. Cov nram qab no yog kev piav qhia txog qhov sib txawv ntawm ob hom tarpaulin.
PE: Cov npe tshuaj yog polyethylene, uas yog cov khoom siv thermoplastic semi-crystalline thiab yog cov khoom ua PE tarpaulins. Yog li dab tsi yog cov yam ntxwv ntawm PE? Peb to taub tias polyethylene tsis muaj ntxhiab, tsis muaj kuab lom, pom tau zoo li siv quav ciab, muaj kub tsis txaus, ua kom dej zoo, zoo hluav taws xob thaiv kev ua haujlwm, thiab siv tau ntawm -70 rau -100 degrees Celsius. , kev ruaj ntseg tshuaj yog qhov zoo.
Qhov ntau ntawm PE tarpaulins yog feem ntau HDPE (High Density Polyethylene), uas muaj kev kub siab, kev ua kom zoo, txhua yam muaj zog thiab tshuaj lom neeg ua haujlwm. Polyethylene yog tsim rau hollow tshuab molding, kev txhaj tshuaj molding thiab extrusion ntawm ntau yam khoom (nyuaj), xws li ntau lub thawv, nets, pob tapes, thiab yuav siv tau raws li cable coatings, kav, profiles, nplooj ntawv, thiab cov zoo li.
Cov ntaub ntawv PE cov khoom siv feem ntau yog hais txog xim nqaij daim tawv, uas yog coated ntawm ob sab ntawm PE woven fabric nrog PE zaj duab xis thiab polypropylene woven daim ntaub. Txheej txheem ntau lawm yog: daim duab-sib tw-npog ob npiv-npo. Txoj kev tsis sib haum ntawm cov dej tsis huv ntawm tus neeg siv lub nkoj tsis zoo, thiab qhov kev tsis ywg dej tsis tas feem ntau tsis tuaj yeem lav tom qab siv ib zaug. Qhov tsis zoo yog tias nws yog ib qho yooj yim rau hnav, thiab qhov kom zoo dua yog tias qhov zoo yog lub teeb, huv si thiab tsis muaj pa phem. Feem ntau siv los siv rau kev ruaj ntseg, tsis muaj dej nag thiab dustproof, nws tsis haum rau kev siv mus sij hawm ntev hauv chaw qhib cua.
PVC tarpaulin yog ib co yas coated polyester tarpaulin los ntawm high-strength polyester canvas, coated nrog polyvinyl chloride (PVC) muab tshuaj nrog ceev nce tus neeg sawv cev, anti-fungal tus neeg sawv cev, anti-aging agent, antistatic, thiab lwm yam. ntawm cov tshuaj additives, yas los ntawm kev kub. Nws muaj cov khoom uas tsis muaj dej tsis zoo, cov ntawv pov thawj, mob khaub thuas, tiv taus cov laus, antistatic, etc .; thiab tawg lub zog, rhuav elongation thiab tearing lub zog ntawm cov khoom no yog zoo dua li cov tsoos tarpaulin; qhov tsos ntawm cov khoom muaj yeeb yuj thiab pleasing rau lub qhov muag. Ntawd yog tshwj xeeb rau kev kho kom tiv thaiv kom txhob muaj cov nyom tiv thaiv. Nws yog ib qho chaw siv dej tsis zoo nkauj thoob ntiaj teb, thiab qhov dav yog qhov loj heev. Thaum tiav qhov khoom tiav lawm, lub seam yuav txo kom zoo dua qub. Lub ntsuas hluav taws xob tuaj yeem siv rau kev tshem tawm qhov kev txhawj xeeb ntawm kev xaws cov pinhole. Raws li cov kev xav tau ntawm cov neeg siv, peb tuaj yeem tsim cov khoom uas muaj kev sib txawv, txawv xim thiab txawv thicknesses.
PVC tarpaulin yog ib daim ntaub thaiv polyester ntaub ntaub thiab ob-sided coated PVC paste cob. Vim hais tias nws yog ib tug txheej txheem dip-molding, nws yog tsim nyob rau hauv ib lub sij hawm. Muaj PVC slurry nyob rau hauv qhov sib txawv ntawm daim ntaub, yog li tus dej tsis zoo yog qhov zoo. Cov txheej txheem ntau lawm: Cov ntaub pua plag zawm npuag - Hlauv pov tseg - ziab thiab zom - calendering thiab cua txias - winding, tam sim no lub tarpaulin rau ntawm lub tsheb, qhov chaw thiab lwm yam khoom tsis zoo yog ua los ntawm PVC tarpaulin. PVC cov khoom muaj cua zoo ua thiab PVC zoo. Cov anti-aging ntawm PVC tarpaulin yog zoo dua PP thiab PE tarpaulin. Cov dej tsis zoo no feem ntau pom tseeb ntawm tag nrho cov dej tsis sib haum. Nws yog siv rau sab nrauv sab nraud. Kev tiv thaiv nag, yug me nyuam los ntawm cov cua uas muaj qhov cua tawv pov thawj, qhov chaw nag, tsheb thauj khoom, lub nkoj npog, thiab lwm yam.
