Nylon webbing, pp webbing thiab polyester webbing yog dav siv hauv lub neej. Tab sis yuav ua li cas paub qhov txawv ntawm peb, thiab yuav ua li cas yuav lub webbing koj xav tau, koj yuav tsum tsis txhob nco cov yam no.
1. Txoj kev combustion:
Nylon (feem ntau hu ua nylon) yog crimped sai thiab yaj mus rau hauv ib lub gel dawb thaum nws nyob ze ntawm cov nplaim taws. Nws melts thiab drips nyob rau hauv cov nplaim taws thiab ua npuas me me. Thaum hlawv, yuav luag tsis muaj nplaim taws thiab nws yog xiav. Flavored los yog celery, nws txias li ib qho nyuaj, dub hlaws ntawm yaj uas tsis yooj yim crushed los ntawm cov ntiv tes.
Polyester yaj nyob ze ntawm cov nplaim taws, nws yuav yaj hauv cov nplaim taws, yuav muaj cov nplaim daj thaum nws kub hnyiab, ntug nplaim yuav xiav xim, thiab yuav muaj cov pa taws dub. Nws yog ib lub pob xim av tsaus uas tuaj yeem tsoo nrog ntiv tes.
Lub pp webbing (polypropylene webbing) melts thiab shrinks thaum nws nyob ze ntawm cov nplaim taws. Nws yuav yaj thaum hlawv hauv nplaim taws, thiab nplaim taws yuav tshwm sim. Lub nplaim sab saud yog daj, thiab qis kawg yog xiav. Nws tseem yuav kub hnyiab tau thaum nws tawm hauv hluav taws, thiab nws yuav emit ib tug paraffin tsw thiab tshauv tom qab hlawv. Nws yog ib lub teeb daj-xim av granule, uas tuaj yeem raug txhuam nrog cov ntiv tes.
2. xav:
Nylon nyiam xis, du thiab mos. Nws tuaj yeem raug loosened tom qab nyem los ntawm tes. Muaj creases thiab nws yuav rov qab maj mam. Qhwv nws nrog koj cov ntiv tes, thiab tsis muaj qhov pom tseeb khawb.
Cov polyester zoo li ntxhib me ntsis, muaj cov quav tom qab pinching thiab loosening nrog ob txhais tes, tseem muaj qee qhov creases tom qab flattening, thiab muaj qhov pom tseeb khawb tom qab khawb nrog rau tes.
Lub pp webbing xav tias rougher dua li nylon thiab polyester, xim ntawm lub webbing kuj dull, thiab cov xov paj yog thicker.
3. Kev ua haujlwm siab:
Txiav cov xov paj me ntsis, ntswj cov xov paj rau hauv ib lub pob, muab tso rau hauv dej, thiab tom qab cov dej ntub dej, pp polypropylene yog ntab rau saum npoo dej, thiab lub dab dej yog nylon lossis polyester.
4. Dyeing:
Nylon webbing yog thawj webbing thiab ces dyeing. Tom qab txiav, cov xov paj yog xim ntawm cov xov paj dawb vim tsis sib xws dyeing.
5. Acid thiab alkali tsis kam
Nylon txoj siv tawv yog alkali-resistant tab sis tsis acid-resistant, 37.5 feem pua hydrochloric acid tuaj yeem yaj, lub teeb-ceev, tsis muaj dej tsis kam, lub hnub ci lub zog ntev txo thiab hloov daj,
Polyester yog alkali resistant tab sis tsis acid resistant. Ib qho concentration ntawm alkali rhuav tshem polyester nto ntawm qhov kub thiab txias kom cov ntaub mos mos, zoo corrosion kuj thiab zoo lub teeb.
pp webbing tiv taus alkali thiab acid.
