Cov txheej txheem txheej rau txheej webbing yog dab tsi?

Tso lus
Cov txheej txheem ua ke ntawm cov txheej txheem coated webbing yuav tsum tau xaiv raws li cov khoom xav tau. Cov txheej txheem txheej txheej yog raws li hauv qab no:
Dry txheej txheem
Cov txheej txheem no yog txheej txheem ib txwm muaj, cov qauv no kuj yooj yim, tsuav yog tus neeg sawv cev rau txheej yog diluted nrog cov kuab tshuaj lossis dej raws li qhov yuav tsum tau ua kom pom tseeb, thiab cov neeg sawv cev uas tsim nyog thiab cov xim sib ntxiv tau ntxiv rau txheej txheej slurry, uas yog tusyees coated rau lub hauv paus daim ntaub nrog lub tsho tiv no, thiab tom qab ntawd ziab thiab ci kom yaj cov kuab tshuaj lossis dej, tsim kom muaj cov yeeb yaj kiab tawv ntawm lub hauv paus daim ntaub.
Cov txheej txheem thev naus laus zis muaj raws li hauv qab no: ntaub npuag xov txheej winding → txheej → kom qhuav → dov (lossis puag) → txias → cov khoom tiav winding.
Wli txheej txheem
Tus neeg sawv cev txheej txheem (xws li polyurethane) tau yaj nrog dimethylformamide (DMF) los ua cov xim pleev. Tom qab txheej, nws tau raus rau hauv dej los ua cov yeeb yaj kiab solidified. Vim tias DMF yog cov dej tsis haum nrog dej, DMF yaj tawm hauv dej, thaum polyurethane muaj cov dej tsis muaj zog hauv cov dej, qhov kev tsub zuj zus tuaj sai, thiab thaum kawg tso nyiaj rau hauv txheej. Thaum lub sijhawm ua cov txheej txheem solidification ntawm txheej, DMF exudes sai los ntawm polyurethane vim cov nyhuv ntawm semi permeable membrane, ua rau channel micropores txiav tawm mus rau saum npoo ntawm zaj duab xis. Yog li ntawd, cov nplaim ntawm cov kua qaub (polymer membrane) yog qhov ntxeem tau. Yog hais tias lub taub ntawm cov micropores raug tswj tsis pub dhau 0.5-5 μ Nws tuaj yeem ua rau hauv cov ntaub vov dej uas tsis yog tsuas yog nqus tau pa tab sis kuj tseem dej thiab noo noo permeable.
Cov txheej txheem thev naus laus zis ntawm txheej txheej ntub yog raws li hauv qab no: lub hauv paus daim ntaub winding, txheej → soaking hauv dej tov solidification → ziab → txias → txias → cov khoom tiav winding.
Melting txoj kev
Nws siv cov thermoplastic resin ua cov txheej txheej ua kom sov thiab tsho tiv no ntawm daim ntaub puag. Thaum nws tau npaj los siv, nws tau kub kub los ntawm cov roj hmab kub lossis hlau kom yaj cov kab, kab lossis network cov kab xo ib txwm nyob ntawm lub hauv paus ntaub dua thiab khi rau cov ntaub txheej txheem. Nws yog feem ntau siv rau los khi dab tshos hauv ob sab phlu. Cov txheej txheem thev naus laus zis nyob ntawm txheej txheej txheej.
Slurry taw tes txoj kev
Nws yog tsuas yog siv rau qhov tsis yog, thiab cov txheej txheem yooj yim yog tib yam li cov ntawv xov xwm ncig.
Hloov zaj duab xis txoj kev ua
Ua ntej, lub txheej txheej tom qab yog txheej ntawm cov ntawv hloov mus los yog cov hlau hle ua ntej los ntawm silicone, tom qab ntawd daim ntaub puag thiab daim ntawv hloov pauv yog sib tshooj rau lub ntsej muag, thiab tom qab ntawd hloov mus rau hauv daim ntaub los ntawm dov thiab nias rau cov menyuam. Tom qab txias, daim ntawv xa mus thiab cov ntaub txheej txheem sib cais sib cais. Hom qauv no yog siv rau ib hom ntaub nrog lub teeb thiab xoob weave thiab rhiab rau qhov nro, xws li leno, knitted ntaub, nonwovens, thiab lwm yam.
Cov txheej txheem thev naus laus zis muaj raws li hauv qab no: hloov ntaub ntawv txheej → daim ntawv daim ntaub lamination → dov thiab nias → txias → sib cais thiab cua ntawm hloov cov ntawv thiab cov ntaub npuag.
