Fiberglass Impregnating Agents: Ib qho tseem ceeb ntawm Fiberglass Forming Thiab Composite Material Interfaces (Tshooj 2) Kev faib tawm ntawm Impregnating Agents
Hauvfiberglasstxheej txheem kev kos duab, sizing tus neeg ua haujlwm ua lub luag haujlwm tseem ceeb. Cov kws kho mob tshwj xeeb no, coated rau saum npoo ntawm nascent fiberglasss, yog cov khoom tseem ceeb kom ntseeg tau tias cov khoom siv fiber ntau zoo, ua tau raws li cov kev xav tau tom qab, thiab thaum kawg ua tiav kev ua tau zoo hauv cov khoom sib xyaw.
Classification ntawm Sizing Agents
Raws li lawv cov khoom tseem ceeb, kev ua kom pom tseeb, thiab qhov kawg ntawm daim ntawv thov, fiberglass sizing agents feem ntau muab faib ua peb pawg:
1. Txhim kho Sizing Agents:
Lub Hom Phiaj Core: Txhawm rau kom ua tiav cov txiaj ntsig kev txhawb zog thiab cov khoom sib txuas ntawm fiberglass hauv cov ntaub ntawv sib xyaw (tshwj xeeb yog thermosetting thiab thermoplastic plastics).
Cov Khoom Tseem Ceeb: Lub hauv paus ntawm cov khoom sib txuas (xws li silanes), ntxiv los ntawm cov yeeb yaj kiab- ua cov tshuaj (feem ntau reactive resins xws li epoxy, polyester, thiab polyurethane emulsions), lubricants, antistatic agents, thiab lwm yam. Coupling agents yog qhov tseem ceeb "bridge molecules" txuas inorganic iav thiab organic polymers.
Cov yam ntxwv: Cov coated precursor fibers (hu ua "txhim kho precursor fibers") feem ntau stiffer thiab muaj cov khoom zoo. Feem ntau yog siv rau kev txiav cov hlua ncaj nraim, hauv SMC / BMC, winding, pultrusion, thermoplastic granulation, thiab lwm yam khoom sib xyaw ua cov txheej txheem sib sau ua ke . 1. Tsis tuaj yeem siv ncaj qha rau hauv textile ua.
2. Textile - hom sizing agents:
Lub hom phiaj tseem ceeb: Txhawm rau muab cov khoom lag luam zoo tshaj plaws rau cov fiberglass filaments (xws li yoog raws, kev ua haujlwm tsis zoo, delamination, antistatic zog, thiab cohesion), ua kom lawv yooj yim dhau los ntawm cov txheej txheem textile xws li warping, weaving, thiab knitting.
Cov khoom tseem ceeb: Cov hmoov txhuv nplej siab lossis roj yog cov yeeb yaj kiab tseem ceeb- ua tus neeg sawv cev thiab khi, ntxiv nrog ntau cov roj nplua nyeem (cov roj ntxhia, roj emulsified), softeners, antistatic agents, thiab lwm yam. Feem ntau tsis muaj lossis tsuas yog ib qho me me ntawm cov khoom sib txuas.
Yam ntxwv: Cov coated filaments (hu ua "textile yarn") yog mos, du, thiab muaj zog cohesion. Feem ntau yog siv los tsim ntau yam fiberglass fabrics (daim ntaub, daim kab xev, lub tes tsho, thiab lwm yam), xaws xov, lim ntaub, thiab lwm yam. Cov txheej feem ntau yuav tsum tau muab hlawv tawm (kub kho) thiab rov siv dua nrog tus neeg sawv cev txhawb zog (post- kho) ua ntej cov khoom sib xyaw tsim; Txwv tsis pub, kev sib txuas ntawm kev sib txuas yog qhov tsis zoo.
3. Txhim kho textile - hom sizing agents:
Lub hom phiaj tseem ceeb: txhawm rau sib npaug ntawm cov khoom siv textile zoo ntawm fiberglass filaments nrog lawv cov khoom siv txhawb zog interfacial hauv cov khoom sib xyaw. Qhov no yog ib qho kev sib haum xeeb ntawm thawj ob hom sizing agents.
Cov khoom tseem ceeb: Nws muaj qee tus neeg sawv cev sib txuas (tab sis qhov kev faib ua feem feem ntau yog qis dua li cov neeg ua kom muaj zog ntshiab), nrog rau cov yeeb yaj kiab- tsim cov tshuaj uas muab cov khoom siv textile (xws li hloov cov hmoov txhuv nplej siab lossis cov khoom siv hluavtaws) thiab cov roj nplua nyeem.
Cov yam ntxwv: Cov khoom ntawm cov khoom ua ntej fiber ntau yog nyob nruab nrab ntawm cov khoom siv txhawb zog thiab cov khoom siv textile, muaj qee qhov kev hloov pauv tau yooj yim thiab kev ua haujlwm, thaum khaws qee qhov kev sib raug zoo nrog cov resins. Nws yog tsuas yog siv los tsim cov ntaub ntawv sib xyaw (xws li qee cov ntaub laminate puag thiab rab koob - xuas nrig ntaus substrates) uas tsis muaj kev cuam tshuam loj heev thiab yuav tsum tau ua qee yam txheej txheem textile. Qee cov khoom tuaj yeem tshem tawm cov ntawv tshaj tawm - cov kauj ruam ua haujlwm thaum lub sij hawm molding, ua kom cov txheej txheem yooj yim dua.
Cov ntsiab lus
Sizing tus neeg sawv cev nyob deb tshaj qhov yooj yim "lubricating txheej"; lawv yog cov ntaub ntawv tseem ceeb thoob plaws tag nrho lub neej ntawm fiberglasss, los ntawm kev kos duab thiab kev tsim mus rau kev tshaj tawm -kev ua thiab kev siv cov khoom siv sib xyaw. Lawv ua tib zoo tsim cov txheej txheem ntau theem endows fiberglass monofilaments nrog bundling peev xwm, kev ua tau zoo, thiab tseem ceeb heev interfacial bonding zog.
Precisely xaiv thiab siv hom tsim nyog tus neeg sawv cev (txhim kho, textile, los yog reinforced textile) raws li kev npaj siv cov khoom kawg yog cov txheej txheem tseem ceeb los xyuas kom meej kev ua tau zoo thiab kev ua haujlwm siab ntawm fiberglass thiab nws cov khoom kawg. Nws zoo kawg nkaus illustrates lub luag hauj lwm haib ntawm nto chemistry nyob rau hauv cov ntaub ntawv engineering.
