Kev faib ua feem
Cov khoom sib txawv ntawm cov hmoov kub yaj yog siv rau cov khoom siv sib txawv.
PA: Polyamide, tseem hu ua nylon, muaj cov dej zoo ntxuav thiab ntxuav kom qhuav. Nws yog tsuas yog tsim los ua cov yeeb yaj kiab kub yaj, uas muaj cov nplaum nplaum zoo rau ntau yam ntaub ntawv xws li textiles, tawv, thiab daim txhuam cev, thiab siv dav.
PES:Polyester, nrog dej zoo ntxuav, tuaj yeem ua rau ob qho tib si nplaum zaj duab xis thiab mesh zaj duab xis, tab sis nws tsis muaj elasticity thiab tsim cov pos huab dawb. Nws muaj adhesion zoo rau textiles, films, sponges, thiab hlau. Txawm li cas los xij, nyob rau hauv daim ntawv thov ntawm kev sib txuas mesh zaj duab xis rau textiles, nws raug nquahu kom xaiv PA ntau dua.
EVA:Vinyl acetate copolymer, nrog qhov nruab nrab ntawm kev ntxuav dej tab sis elasticity. Thaum tsis siv, nws muaj qhov pos huab thiab ua pob tshab tom qab siv. Nws muaj zoo foaming adhesion rau qee cov roj hmab, polypropylene, thiab daim txhuam cev, thiab muaj kev txwv zoo hauv daim ntawv thov kev sib txuas. Txawm li cas los xij, hauv lwm daim ntawv thov, xws li cov ntaub ntawv phab ntsa thiab cov khau roj hmab, nws muaj qee yam kev lag luam, kev siv kub tsawg, thiab tus nqi qis.
TPU:polyurethane, nrog zoo elasticity thiab dej washability, yog tsuas yog siv raws li ib tug nplaum zaj duab xis. Nws yog dav siv hauv cov khoom siv khau thiab khaub ncaws, thiab tuaj yeem siv rau qhov sib txawv ntawm qhov kub thiab txias (tsis kub tsis muaj elastic, nruab nrab kub elastic, kub siab elastic). Nws muaj adhesion zoo rau textiles, tawv, films, thiab sponges, thiab kuj yog ib tug nrov ntau yam nyob rau hauv nplaum films.
