Yuav ua li cas hloov pauv ntawm tus neeg sawv cev sizing txuas rau saum npoo ntawm fiberglass thaum lub sij hawm ziab?
(1) Ua ntej ziab. Thaum lub sij hawm kev kos duab, ib txheej ntawm sizing tus neeg saib xyuas zaj duab xis yog coated rau ntawm qhov chawfiberglassnrog lub thickness ntawm 0.5 ~ 2μm. Cov yeeb yaj kiab no yog cov qauv ntau theem, nrog rau homogeneous sizing tus neeg saib xyuas raws li cov theem txuas ntxiv thiab cov emulsion hais ntawm ntau qhov sib txawv raws li cov theem dispersed. Lub sijhawm no, Si-OH daim ntawv cog lus nyob rau hauv cov coupling tus neeg sawv cev molecules pib ua ke nrog Si-OH daim ntawv cog lus ntawm lub iav nto thiab mloog zoo rau ntawm lub iav nto.
(2) Kev ua kom qhuav. Thaum lub sij hawm ziab, raws li cov dej evaporates tsis tu ncua, qhov concentration ntawm tus neeg sawv cev ntub dej nce, cov emulsion pib tawg, cov emulsion hais condense, thiab cov uas tsis yog-ionic lubricant pib migrate mus rau cov kua-gas interface, piv txwv li, lub nto. txheej. Cov ntsev inorganic ntawm tus neeg sawv cev antistatic crystallizes vim supersaturation. Cov txheej txheem no txuas ntxiv mus txog rau thaum lub thickness ntawm cov yeeb yaj kiab ntub dej raug txo rau 0.05 ~ 0.2μm. Tom qab cov tshuaj qhuav qhuav, nws dhau los ua ntu ntu ntu me me, thiab cov khoom sib txawv ntawm cov emulsions sib sau ua ke thiab tswj hwm lawv cov ntsiab lus tseem ceeb uas tsis muaj kev sib koom ua ke. Nyob rau lub sijhawm no, cov khoom siv ntawm cov yeeb yaj kiab ntub dej yog qhov tsis zoo, cov xov paj tsis zoo hnav tsis zoo, thiab qhov tawv nqaij tsis siab.
(3) Tom qab tswj qhov kub thiab txias rau ib lub sijhawm, cov khoom emulsion ntawm ntau cov yeeb yaj kiab tsim cov neeg ua haujlwm pib ncav cuag qhov kub thiab txias, thiab cov molecules diffuse nrog ib leeg. Txawm hais tias lawv tsis tuaj yeem tsim cov qauv zoo ib yam (qhov no muaj feem xyuam rau cov kev tsis sib haum xeeb ntawm ntau yam emulsion resins, viscosity ntawm molten resin, molecular polarity, thiab cov qauv tshuaj zoo sib xws ntawm cov resins), qhov sib cuam tshuam ntawm emulsion hais tau ploj mus. , thiab ntau yam emulsion resins thiab dej-soluble resins tau sib koom ua ke los ua ib zaj duab xis ua tiav thiab txuas ntxiv. Yog tias muaj tus neeg sawv cev sib txuas hauv cov mis ntawm tus neeg sawv cev ntub dej thiab tus neeg sawv cev ua yeeb yaj kiab, tus neeg sawv cev sib txuas pib ua haujlwm nyob rau lub sijhawm no, ua rau cov resin tsim cov qauv network thiab nce qhov hnyav molecular, thaum tsis muaj -ionic lubricant txuas ntxiv mus rau qhov chaw. Lub sijhawm no, cov xov paj tau zoo hnav tsis kam, txhim kho kev nruj, thiab lub zog kuj nce mus txog qhov siab tshaj plaws. Txawm li cas los xij, kev ziab dhau tuaj yeem ua rau muaj teeb meem zoo, xws li yellowing ntawm qhov chaw.
Tus neeg sawv cev sizing feem ntau tsis tuaj yeem tsim cov yeeb yaj kiab txuas ntxiv thiab ua tiav rau ntawmfiberglassib fiber. Vim hais tias cov sizing tus neeg saib xyuas zaj duab xis yog nyias thiab cov sib thooj latex hais yog loj, cov latex resin hais tom qab ziab feem ntau protrude los ntawm cov zaj duab xis nto, thiab cov protrusions los yog txawm me me spherical particles khi ib fibers ua ke.
