Cov Khoom Uas Tsis Zoo Tshaj Plaws Thaum PTFE High-Temperature Fabric Drying - thiab Yuav Ua Li Cas Tiv Thaiv Lawv

Kev ziab yog ib kauj ruam tseem ceeb hauv PTFE high-temperature npuag ntau lawm. Tom qab fiberglass ntaub yog impregnated nrog PTFE emulsion, nws dhau los ntawm lub qhov cub kom qhuav kom tshem tawm dej thiab fuse cov PTFE hais mus rau hauv ib tug tas mus li txheej.

Txawm li cas los xij, cov txheej txheem ziab tuaj yeem qhia ntau yam tsis xws luag - los ntawm cov kab nrib pleb thiab pinholes mus rau delamination thiab warpage. Cov kev tsis zoo no tshwm sim los ntawm kev sib cuam tshuam ntawm cov khoom emulsion, cov qauv substrate, thiab cov kev ua kom qhuav.

Aokai PTFE tau kho cov txheej txheem ziab kom zoo thoob plaws ntau yam khoom. Phau ntawv qhia no piav qhia txog kaum feem ntau qhov ua kom qhuav tsis xws luag, lawv cov hauv paus hauv paus, thiab cov kev daws teeb meem.

Txheej Cracking thiab Crazing

Cov tsos mob: Cov kab nrib pleb zoo los yog dav kis thoob plaws ntawm daim ntaub; Hauv qhov xwm txheej hnyav, cov txheej txheej tawm hauv cov flakes.

Root ua rau:

• Kev ziab sai heev - cov dej nrawm nrawm ntawm qhov chaw ua rau cov tawv nqaij qhuav. Internal vaporized dej lov los ntawm cov zaj duab xis nto los yog generates loj shrinkage kev nyuaj siab.

• Cov ntsiab lus PTFE siab - ua rau lub ntim loj heev thaum lub sij hawm sib sau ua ke.

• Qhov kub kom qhuav heev los yog huab cua kub dhau - ua rau cov tawv nqaij tawv thaum cov txheej sab hauv tseem tsis qhuav, ua rau muaj kev ntxhov siab thiab ua rau tawg.

Kev daws:

• Siv cov gradient ziab kom qhuav: qhov kub thiab txias hauv thawj cheeb tsam, maj mam nce.

• Txo qhov pib ziab kom qhuav (kub thiab airflow).

• Optimize emulsion solids cov ntsiab lus - zam cov khib nyiab ntau dhau.

Txheej Migration (Electrophoretic Migration)

Cov tsos mob: Cov ntaub nto yog nplua nuj nyob rau hauv resin thiab zoo nkaus li glossy, thaum tsis txaus resin nyob rau hauv qhov sib txawv ntawm cov khoom fiber ntau. Kev soj ntsuam hla ntu qhia pom cov qauv tsis sib xws nrog cov txheej txheej ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.

Root ua rau:

• Fine PTFE hais migrate rau saum npoo nrog rau cov dej ntws raws li ya raws evaporates sab nraud.

• Tsis tiav ziab tawm cov dej seem thiab tsim cov dej zoo li cov blemishes dawb.

Chalking:

• Kev kub siab heev los yog huab cua kub ncaj qha cuam tshuam tiv thaiv qhov chaw PTFE cov khoom los ntawm kev sib xyaw ua ke rau hauv ib zaj duab xis, tawm hauv cov hmoov xoob.

• Tsis ruaj tsis khov emulsion yuav tawg thiab agglomerate rau hauv cov hmoov clumps thaum ziab.

Kev daws:

• Tsis txhob ziab kom qhuav heev.

• Xyuas kom tiav sintering - tsis yog ziab xwb.

• Tswj cov ntsiab lus surfactant hauv emulsion formulation.

Yellowing thiab Coking

Cov tsos mob: Lub txheej hloov daj, txawm tias muaj xim av scorch.

Root ua rau:

• Kev kub kom qhuav los yog lub sij hawm nyob ntev ntev ua rau cov thermal oxidative decomposition ntawm surfactants, thickeners nyob rau hauv emulsion, thiab residual fiberglass sizing agents.

• PTFE nws tus kheej muaj cov cua kub zoo heev, tab sis cov khoom siv ntxiv tsis tuaj yeem tiv taus cua sov.

• Tsis sib xws infrared cua sov tsim cov cheeb tsam overheating.

Kev daws:

• Teem kom qhuav qhov kub thiab txias hauv qab ntawm qhov pib decomposition ntawm tag nrho cov additives (feem ntau <380 ° C rau PTFE sintering, tab sis tsis txhob muaj zog> 350 ° C).

• Xyuas kom cov cua sov sib xws thoob plaws qhov dav qhov cub.

• Siv high-purity, thermally ruaj khov additives.

H2: 6. Txheej Lifting thiab Delamination

Cov tsos mob: Cov txheej txheem sib cais los ntawm fiberglass substrate interface, tev tawm hauv cov nplooj ntawv loj lossis detachable los ntawm rubbing.

Root ua rau:

• Qhuav shrinkage kev nyuaj siab tshaj li interfacial bonding quab yuam.

• Tsis huv los yog tsis kho fiberglass nto ua rau tsis zoo emulsion wetting.

• Uneven shrinkage los ntawm ib sab ceev kom qhuav.

• Resin depletion ntawm lub substrate interface tshwm sim los ntawm txheej migration ua ib tug tsis muaj zog ciam teb txheej.

Kev daws:

• Xyuas kom huv si saum npoo thiab pretreatment ntawm fiberglass (xws li, cua sov tu kom tshem tawm qhov loj me).

• Siv silane coupling agents los yog adhesion txhawb nqa.

• Optimize drying profile kom txo qis kev ntxhov siab.

• Tiv thaiv kev tsiv teb tsaws ntau dhau.

Txiv kab ntxwv Peel, Leveling tsis zoo, thiab ntxhib nto

Cov tsos mob: Txiv kab ntxwv-tev-zoo li tsis sib xws textures lossis tag nrho matte ntxhib nto tsis muaj gloss.

Root ua rau:

• Kev ua haujlwm tsis zoo ntawm PTFE emulsion.

• Ntau dhau qhov kub pib ziab kom qhuav sai sai thickens zaj duab xis saum npoo thiab tshem tawm cov peev txheej.

• Cov cua kub ncaj qha cuam tshuam cov txheej ntub dej.

• Overly prominent ntaub weave kev ntxhib los mos yuav tsis tau tag nrho los ntawm nyias txheej txheej.

Kev daws:

• Siv cov tshuaj leveling yog tias tsim nyog.

Warpage thiab Shrinkage Deformation

Cov tsos mob: Cov ntaub tsis sib xws, curled selvedges, thiab pom dav dav shrinkage.

Root ua rau:

• Thermal shrinkage ntawm fiberglass ntaub nyob rau hauv alternating humid thiab qhuav tshav kub tej yam kev mob, tshwj xeeb tshaj yog nrog tsis tsim nyog warp / weft nro.

• Tsis sib haum thermal shrinkage tus nqi ntawm txheej thiab substrate.

• Kev ziab ib leeg los yog qhov kub thiab txias gradients tsim qhov sib txawv shrinkage ntawm ob sab ntawm cov ntaub.

Kev daws:

• Khaws qhov sib npaug ntawm warp / weft nro thaum ziab.

• Siv ob sab cua sov kom sib npaug shrinkage.

• Pre-shrink lub fiberglass ntaub ua ntej txheej.

Nto qhuav Tab sis sab hauv ntub - yob thaiv

Cov tsos mob: Cov txheej txheej xav tias qhuav rau qhov kov tsis tau khaws cov dej noo sab hauv. Cov khaubncaws sab nraud povtseg lo rau ib leeg tom qab winding, nrog lub suab nrov nrov los yog txheej puas thaum lub sij hawm unwinding.

Root ua rau:

• Qhov kub kom qhuav ua ke nrog lub sijhawm nyob luv luv ua rau daim tawv nqaij uas thaiv cov dej vapor tawm sab hauv.

• Tsis txaus cua txias tom qab tawm ntawm lub qhov cub kom qhuav tawm cov cua sov seem thiab ua rau cov surfactants tacky.

• Tsis tiav ziab tawm cov dej seem thiab cov khoom ntxiv los ua cov nplaum nplaum.

Kev daws:

• Siv qhov kub kom qhuav qis nrog lub sijhawm nyob ntev dua - cia cov dej noo kom khiav tawm maj mam.

• Xyuas kom muaj cua txaus thiab dehumidification hauv qhov cub.

• Muab qhov txias txaus ua ntej winding (lub hom phiaj <40 ° C).

Thick Selvedges thiab Uneven Txheej Thickness

Cov tsos mob: Cov txheej ntawm cov npoo ntawm cov ntaub yog tuab dua li qhov nruab nrab ntawm qhov chaw, lossis cov kab txaij thickness sib txawv tshwm thoob plaws lub vev xaib.

Root ua rau:

• Kev ya raws ceev ceev ntawm selvedges tsav emulsion tsub zuj zuj thiab txav mus rau cov npoo thaum ziab - 'Cov nyhuv kas fes.'

• Cov cua kub tsis sib xws ua rau muaj ntau yam kev ziab kom qhuav.

Kev daws:
