Dissolution txoj kev rau daim ntawv yas composite hnab

Cov hnab yas thiab cov hnab yas sib xyaw ua ke feem ntau yog ua los ntawm polypropylene lossis polyethylene resin, nrog me me ntawm cov khoom siv ntxiv. Tom qab sib tov, cov yas zaj duab xis yog melted thiab extruded los ntawm ib tug extruder, txiav mus rau hauv txhob lo lo ntxhuav, stretched hauv qab no lub melting kub ntawm resin, thiab ua rau hauv high-strength thiab tsis tshua muaj elongation ca lo lo ntxhuav los ntawm molecular orientation thiab tshav kub. Tom qab ntawd, lawv raug mob, woven, (laminated), loaded thiab sewn rau hauv hnab yas woven thiab composite yas woven hnab. Cov hnab yas sib xyaw ua ke yog ua los ntawm cov hnab ntawv uas tsim nyog, laminated, sib txuas, thiab sewn nrog daim ntawv strips ntawm cov npoo. Ntshiab cua sov: Muab daim ntawv saum npoo tiaj tiaj rau ntawm lub phaj cua sov thiab tom qab ntawd ua kom sov los ntawm lub phaj cua sov; Thaum kub nce mus txog 150 degree thiab 280 degree; Tom qab cua sov rau lwm 20 mus rau 50 vib nas this, cov yas ntawm cov ntawv yas sib xyaw yuav pib deform, ntsws, thiab cais tawm ntawm daim ntawv. Txoj kev no tuaj yeem cais cov ntawv pov tseg cov hnab yas sib xyaw uas tsis tuaj yeem ua tiav ua ntej, yog li ua kom rov siv tau cov ntawv pov tseg, xws li: ua cov ntawv thiab cov ntawv ntawm cov ntawv pov tseg; Siv cov hnab yas rov ua dua tshiab, tom qab ntawd rov kos lawv los ua cov hnab yas sib xyaw, lossis txhaj rau hauv cov khoom yas tshiab. Nws tuaj yeem hloov cov hnab yas khib nyiab pov tseg rau hauv cov khoom muaj nqis, thiab tseem tuaj yeem daws teeb meem ib puag ncig, ua rau nws muaj txiaj ntsig zoo rau kev lag luam thiab kev sib raug zoo. Txoj kev sib cais siv cov ntawv pov tseg cov hnab yas sib xyaw ua cov khoom siv raw, thiab cais lawv mus rau hauv daim ntawv monomers los ntawm dissolving lawv hauv cov kuab tshuaj organic. Tom qab ntawd, cov txheej txheem pulping thiab papermaking yog nqa tawm, thiab cov khoom siv raw tau muab tso rau hauv cov organic solvent dissolution tank. Tom qab cua sov thiab nplawm, cov txheej yas yog yaj, thiab cov ntawv monomers thiab lwm cov txheej monomer raug sib cais. Tom qab ziab, cov ntawv xaiv tau siv rau pulping thiab papermaking. Txoj kev no yog qhov yooj yim thiab ua tau, nrog rau kev sib cais siab thiab cov txiaj ntsig zoo rau cov hnab yas sib xyaw. Cov ntawv sib cais tuaj yeem siv rau kev ua cov ntaub ntawv, txo cov nqi tsim khoom ntawm papermaking; Woven hnab tuaj yeem siv rau kev rov ua dua tshiab thiab rov ua dua tshiab rau hauv cov hnab ntim khoom lossis lwm yam khoom yas, yog li ua tiav cov peev txheej rov ua dua tshiab, tiv thaiv ib puag ncig, thiab ua rau muaj txiaj ntsig zoo rau Tuam Tshoj txoj kev tiv thaiv ib puag ncig.
