1. Ua pa
Kev ua pa yuav tsum raug txiav txim siab rau tarpaulins, tshwj xeeb tshaj yog rau cov tub rog tarpaulins.Qhov cuam tshuam ntawm huab cua permeability muaj xws li cov qauv substrate, qhov ntom ntom, cov khoom siv, hom tshuaj ntxuav dej tsis huv, resin adhesion, thiab lwm yam. Nrog rau qhov nce ntawm resin adhesion, huab cua permeability ntawm tarp txo.Tau kawg, nws nyob ntawm cov tshuaj ntxuav tes siv.Feem ntau hais lus, breathable tarpaulin feem ntau yog ua los ntawm cov wax dawb los yog acrylonitrile resin huv paj rwb, vinylon, varnished nylon thiab lwm yam staple npuag khoom.
2. Lub zog tensile
Tarpaulin yuav tsum lees txais txhua yam kev nruj thaum siv, xws li qhov nro ruaj khov;Nws yuav raug cuam tshuam los ntawm cua, nag thiab lwm yam ntxiv zog hauv cov txheej txheem thov.Txawm hais tias muaj kev cuam tshuam los ntawm cov quab yuam sab nraud, lawv tseem yuav tsum tau ua kom zoo li qub, tsis yooj yim deformed, uas yuav tsum tau tarpaulin nrog lub zog tensile siab, thiab nws yuav tsum tsis txhob sib txawv ntawm lub zog tensile ntawm latitude thiab longitude.Feem ntau hais lus, nws yuav tsum xaiv lub zog siab polyester, vinylon thiab lwm cov ntaub fiber ntau ntev rau lub hauv paus ntaub.Lub zog ntawm cov khoom siv fiber ntau thiab qhov ntom ntawm cov ntaub ua ntej txiav txim siab lub zog ntawm cov khoom.
3.Txoj kev ruaj ntseg
Raws li eaves tsev pheebsuab thiab lub ru tsev tsev pheeb suab loj, ntaub yuav tsum tsis txhob ntau elongate yog hais tias feem ntau siv nyob rau hauv nro, , nws seem stability nyob ntawm lub creep zog ntawm cov khoom.
4.Tearing zog
Kev puas tsuaj ntawm tarpaulin feem ntau yog tshwm sim los ntawm kev tsim kua muag, yog li lub zog tsim kua muag yog qhov qhia tseem ceeb ntawm tarpaulin.Lub zog tsim kua muag muaj feem cuam tshuam txog seb lub tarp yuav tawg vim qhov cuam tshuam ntawm cov khoom ya, los yog vim qee qhov nws yuav kis tau ib ncig tom qab lub qhov tsim, thiab tsim kom muaj cov qauv tawg loj.Yog li ntawd, thaum lub nro loj dua, lub tarpaulin yuav tsum tsis tsuas yog muaj zog tensile ntau dua, tab sis kuj muaj zog dua tearing.
5. Dej tsis kam
Kev tiv thaiv dej yog ib qho tseem ceeb ntawm tarpaulin.Tom qab soaking, vinyl chloride resin tau ntim rau hauv qhov khoob ntawm cov ntaub los ua ib zaj duab xis.Yog hais tias tus nqi ntawm resin adhesion nyob rau hauv ib cheeb tsam ntau tshaj ib tug tej degree, dej kuj yuav tsis muaj teeb meem.Yog tias cov yeeb yaj kiab nyias nyias, nws yooj yim tawg thiab tuaj yeem tsim cov av nkos thaum nws raug khoov, muag muag lossis pom kev hnav.
6. Hluav taws kub tsis kam
Nyob rau hauv cov nqe lus ntawm daim ntawv thov kev ruaj ntseg, lub tarpaulin yuav tsum muaj zoo nplaim retardance.Cov nplaim hluav taws kub hnyiab tuaj yeem tau txais los ntawm kev xaiv cov nplaim hluav taws xob thiab cov khoom siv hluav taws xob, lossis los ntawm kev ntxiv cov nplaim hluav taws kub rau cov txheej txheem txheej.Tus nqi ntawm cov nplaim retardants ntxiv yog ncaj qha ntsig txog cov nplaim hluav taws.
