Dab tsi yog cov khoom ntawm fiberglass sizing?
(1) Zaj movie qub. Cov yeeb yaj kiab yav dhau los yog qhov sib txuas ua ke hauv tus neeg sawv cev sizing. Nws yog lub ntsiab tivthaiv rau kev ua tiav ib leeg-filament bundling thiab tswj kev ncaj ncees ntawm thawj filament. Nws txiav txim siab qhov tawv thiab softness ntawm thawj filament kom tau raws li tus txheej txheem yuav tsum tau ntawm ntau homfiberglasscov khoom. Cov khoom siv no yog siv rau hauv qhov loj tshaj plaws hauv cov qauv sizing tus neeg sawv cev, suav txog 2% -15%, thiab muaj kev cuam tshuam tseem ceeb ntawm kev ua haujlwm thiab kev ua haujlwm ntawm tus neeg sawv cev sizing. Nws yog qhov tseem ceeb tshaj plaws nyob rau hauv tus neeg sawv cev sizing. Cov qauv sib txawv siv ntau hom raw khoom. Qee lub sij hawm ntau tshaj ob zaj duab xis yav dhau los yog siv los ua kom tiav cov txiaj ntsig tau teev tseg los ntawm sizing tus neeg sawv cev mis.
(2) Coupling tus neeg sawv cev. Kev siv cov coupling tus neeg sawv cev yog ib qho ntawm cov yam ntxwv ntawm tus neeg sawv cev kho kom zoo dua qub. Los ntawm nws tus kheej ntau yam sib txawv reactive pawg, nws ua kefiberglassnrog cov polymers xws li resin, plays lub luag hauj lwm txuas, ua tiav kev sib txuas zoo ntawm cov khoom siv tsis zoo thiab cov organic, thiab ua rau cov khoom siv fiberglass ntxiv kom tau txais cov txiaj ntsig zoo ntawm daim ntawv thov. Cov khoom sib txawv sib txawv muaj qhov sib txawv ntawm lub zog ntawm cov khoom siv fiberglass. Nws yog ib qho tsim nyog yuav tsum xaiv hom kev sib txuas ntawm tus neeg sawv cev raws li cov khoom siv matrix thiab nws tus neeg sawv cev kho. Feem ntau, tus neeg sawv cev sib txuas yog siv nyob rau hauv cov qauv sizing tus neeg sawv cev ntawm qhov ntau npaum li cas ntawm 0.2% -1.2%.
(3) Lubricant. Lubricant yog hais txog ib yam khoom uas lubricates saum npoo ntawmfiberglassthiab txo qhov hnav hauv lub xeev ntub dej (cov txheej txheem ziab hlau qhuav) thiab lub xeev qhuav (raws li fiber ntau debonding thiab textile ua). Nws qhov ntau npaum li cas hauv tus neeg sawv cev sizing feem ntau yog 0-5%. Hom thiab ntau npaum li cas ntawm lubricants siv nyob rau hauv sizing tus neeg sawv cev rau txawv lub hom phiaj sib txawv heev.
(4) Antistatic tus neeg sawv cev. Antistatic tus neeg sawv cev tuaj yeem txo cov nyhuv zoo li qub ntawm fiberglassthaum ua thiab siv. Nws cov nyhuv yog tshwj xeeb tshaj yog nyob rau hauv lub sizing tus neeg sawv cev rau luv luv-txiavfiberglass. Lub hauv paus ntsiab lus ntawm kev ua haujlwm tseem ceeb ntawm tus neeg sawv cev antistatic yog txo cov kev sib txhuam coefficient thiab tsim cov channel conductive.
(5) Pab cov khoom xyaw
1. Tus neeg saib dej ntub dej. Wetting tus neeg sawv cev yog ib yam khoom uas muaj kev ua haujlwm saum npoo av. Nws tuaj yeem txo qhov nro ntawm tus neeg sawv cev ntub dej kom tus neeg sawv cev ntub dej tau yooj yim dua ntub dej ntawm qhov chaw.fiberglassthiab ua tiav cov nyhuv ntawm uniformly txheej lubfiberglass.
2. pH adjuster. Cov txheej txheem ntub dej feem ntau yog nruab nrab lossis tsis muaj zog acidic. Tus pH adjuster feem ntau yog siv los kho qhov ruaj khov ntawm tus neeg sawv cev ntub dej thiab xyuas kom zoo tshaj plaws ntawm kev siv tus neeg sawv cev sib txuas. Feem ntau siv pH adjusters muaj xws li formic acid, acetic acid, citric acid, oxalic acid, ammonia dej, organic amines, thiab lwm yam. Xav tias tus neeg sawv cev ntub dej yog nyob rau hauv kev sib cuag ncaj qha nrog tib neeg thiab tshuab, pH tus nqi nyob rau hauv cov mis nyuj yog nyob rau hauv ntau yam. ntawm 4-7. Rau qee tus neeg ua dej ntub dej, lawv cov yeeb yaj kiab-tsim tus neeg sawv cev emulsion tsuas yog siv tau ruaj khov hauv cov kab mob alkaline lossis tsuas tuaj yeem ua tiav qhov xav tau viscosity. Tus nqi pH ntawm tus neeg sawv cev ntub dej yog tswj ntawm 8-11, tab sis nws yog qhov tsawg.
3. Plasticizer. Ib yam khoom ntxiv rau cov txheej txheem ntub dej los txhim kho qhov yooj yim ntawm cov yeeb yaj kiab-tsim tus neeg sawv cev. Thaum npaj tus neeg sawv cev impregnation, qee zaum nws tuaj yeem ntxiv ncaj qha rau tus neeg sawv cev ua yeeb yaj kiab. Feem ntau siv plasticizers suav nrog dibutyl phthalate, dioctyl phthalate, tributyl phosphate, thiab lwm yam. Kev siv cov monofilament plasticizers qee zaum cuam tshuam rau permeability ntawm cov xov paj thiab tsuas yog siv thaum qhov kev ua tau zoo los ntawm impregnation tus neeg sawv cev system tsis ua raws li qhov yuav tsum tau ua.
4. Tus neeg sawv cev sib txuas. Tom qab tus neeg sawv cev sib txuas ntxiv mus rau lub impregnation tus neeg sawv cev, nws yuav tsim cov tshuaj tiv thaiv kev sib txuas nrog qee cov yeeb yaj kiab-tsim tus neeg sawv cev hauv tus neeg sawv cev impregnation thaum lub sij hawm ziab ntawm thawj cov lo lo ntxhuav, thiab hloov cov qauv ntawm cov qauv ntawm cov qauv hauv lub cev mus rau hauv. ib tug peb-dimensional network qauv, yog li ua rau lub hardness ntawm cov zaj duab xis, uas yog heev pab tau rau kev txhim kho ntawm lub hard yarn, tab sis nyob rau tib lub sij hawm nws yuav ua rau cov teeb meem ntawm nyuaj impregnation ntawm cov xov paj thiab tsis zoo stability. tus neeg sawv cev impregnation.
5. Cov tshuaj tua kab mob thiab cov tshuaj tua kab mob. Thaum lub impregnation tus neeg sawv cev mis muaj hmoov txhuv nplej siab, gelatin, hydrogenated zaub roj, stearic acid los yog oleic acid lubricants, thiab lwm yam., uas yog prone rau kev noj nyiaj txiag, mildew, thiab deterioration, preservatives los yog fungicides yuav tsum tau.
6. Defoaming tus neeg sawv cev. Cov zaj duab xis-forming tus neeg sawv cev emulsion thiab lubricant nyob rau hauv lub wetting tus neeg saib xyuas muaj tej yam nto active cov khoom xyaw, uas yog ib qho yooj yim los ua npuas ncauj thaum stirring thiab siv, ua rau inconvenience nyob rau hauv ntau lawm thiab daim ntawv thov. Qee zaum defoamers yuav tsum tau ntxiv kom tshem tawm ua npuas ncauj. Defoamers feem ntau yog cov tshuaj silicone, uas feem ntau yog txau rau ntawm qhov chaw me me tom qab tus neeg sawv cev ntub dej tau npaj.
