Fiberglass Fabric Pre-Drying: Yuav ua li cas tswj qhov kub thiab txias kom raug

Views: 0 Author: Site Editor Publish Time: 2026-06-16 Keeb Kwm: Qhov chaw

Ua ntej PTFE txheej, resin impregnation, los yog lamination, fiberglass ntaub yuav tsum tau ua ntej qhuav. Lub hom phiaj tsuas yog tshem tawm cov dej noo, lossis nws yuav cuam tshuam nrog kev kub hnyiab ntawm cov khoom siv hluav taws xob (dewaxing), los yog ua kom sov cov ntaub rau qhov kub thiab txias ua ntej txheej. Txhua lub hom phiaj yuav tsum muaj qhov sib txawv ntawm qhov ntsuas kub thiab lub sijhawm.

Qhov tsis raug tuaj yeem ua rau tsis zoo impregnation, tsis muaj zog sib txuas, ntaub yellowing, poob ntawm lub zog - lossis txawm tias tag nrho cov khoom seem.

Aokai PTFE muaj kev paub dhau los hauv iav fiber ntau ua. Phau ntawv qhia no piav qhia txog peb yam kev kho mob tseem ceeb, lawv qhov ntsuas kub zoo tshaj plaws, kev tswj xyuas lub sijhawm, thiab cov lus qhia ua haujlwm kom tau txais txiaj ntsig zoo ib yam.

Peb Lub Hom Phiaj Kev Kho Mob tseem ceeb thiab lawv qhov kub thiab txias

Lub Hom Phiaj Kho Mob	Qhov kub thiab txias	Lub Hom Phiaj Core	Tej kev siv
Kev tshem tawm noo noo (feem ntau)	105 ° C - 120 ° C	Tshem tawm cov dej adsorbed yam tsis muaj kev puas tsuaj rau sizing agents	Lamination, PTFE / silicone txheej, prepreg layup
Dewaxing / thermal tu (sizing tshem tawm)	300 ° C - 450 ° C	Ua tiav hlawv tawm ntawm textile sizing (cov hmoov txhuv nplej siab, PVA, thiab lwm yam)	Cov txheej txheem yuav tsum tau ua kom huv si saum npoo: resin impregnation, tshuaj kho mob
Preheating rau cov txheej txheem hloov	60 ° C - 100 ° C	Nce cov ntaub kub rau txheej los yog impregnation	Cov kab txuas txuas ntxiv, ua ntej cov kua nplaum tso dej; tiv thaiv resin viscosity nce los ntawm cov ntaub txias

Routine Moisture Tshem Tawm - Cov Txheej Txheem Feem Ntau

Qhov no yog cov txheej txheem ua ntej ziab rau feem ntau cov ntaub ua ntej txheej lossis lamination. Lub hom phiaj yog kom dehumidification thaum tiv thaiv cov sizing tus neeg sawv cev uas tuav cov fibers ua ke.

1. Kev tswj qhov kub thiab txias

Rau cov khoom siv hluav taws xob thiab cov ntaub ntawv txhawb nqa: tuav 105 ° C - 120 ° C.
Rau fabrics kho nrog silane coupling agents : khaws kub hauv qab 110 ° C kom tsis txhob tawg cov coupling bonds.
Qhov kub sib txawv hauv qhov cub yuav tsum tau tswj tsis pub dhau ± 5 ° C kom tsis txhob muaj cua sov hauv zos.

2. Lub sij hawm tswj (raws li ntaub hnyav)

Npuag hnyav	Lub Sijhawm Pom Zoo
Cov ntaub nyias nyias (<100 g / m²)	10-15 feeb
Nruab nrab & hnyav ntaub (200 - 400 g / m²)	20-30 feeb
Cov ntaub tuab / lev (> 600 g / m²)	1-2 teev los yog ntev dua

Kev txiav txim siab txiav tawm: qhov hnyav tas li tau ua tiav thaum qhov sib txawv ntawm qhov sib txawv ntawm ob qhov kev ntsuas sib law liag yog tsawg dua 0.1%. Rau cov ntaub ntawv dov, dai lawv xoob lossis siv cov strips spacer thaum ziab kom tsis txhob muaj teeb meem ntawm sab nrauv qhuav tab sis damp sab hauv.

3. Cov ntsiab lus tseem ceeb tswj

Lub qhov cub yuav tsum tau yuam kom dehumidification . Qhib cov huab cua ntshiab kom tso pa tawm raws sijhawm.
Tsis txhob overload lub qhov cub; xyuas kom airflow nyob ib ncig ntawm txhua yob los yog ntawv.

Dewaxing thiab Thermal Cleaning - Rau Ultra-Clean Surfaces

Thaum cov ntaub yuav tsum tsis pub dawb ntawm cov organic sizing cov neeg ua haujlwm (xws li, ua ntej cov khoom ua haujlwm siab impregnation rau aerospace lossis high-temperature composites), thermal tu yuav tsum tau ua.

1. Kev tswj qhov kub thiab txias

Volatilization & haus luam yeeb theem: nyob ib ncig ntawm 300 ° C. Yuav tsum muaj cov pa oxygen txaus thiab cov pa luam yeeb zoo.
Residue burnout theem: maj mam nce kub rau 380 ° C - 450 ° C thiab tuav, kom tag nrho oxidize residual carbon.
Tsis txhob siab tshaj 500 ° C - txwv tsis pub cov fiberglass nws tus kheej yuav nkig thiab puas.

2. Lub sijhawm tswj

Rau kev nruam thermal desizing furnaces, kho cov ntaub khiav ceev kom cov ntaub nyob twj ywm nyob rau hauv high-temperature cheeb tsam rau ob peb mus rau ntau tshaj kaum feeb, nyob ntawm seb cov ntaub hnyav. Cov ntaub hnyav dua xav tau ntev dua.

3. Kev lees txais

Poob ntawm ignition (LOI) yuav tsum tsawg dua 0.1%. Qhov no yog tus qauv kub.
Kev sim teb yooj yim: Ignite ib lub ces kaum ntaub nrog lub teeb. Cov khoom tsim nyog tsim tsis muaj pa luam yeeb dub lossis tsw ntxhiab, nrog cov tshauv tsawg kawg nkaus.
Cov ntaub tsim nyog zoo nkaus li dawb los yog khaws nws cov xim qub, tsis muaj xim dub lossis daj streaks.

4. Cov ntawv ceeb toom tom qab

Dewaxed fiberglass npuag muaj kev ua haujlwm siab . Hloov nws mus rau cov txheej txheem impregnation tom ntej tam sim ntawd, los yog muab ntim thiab ntim kom zoo kom tsis txhob rov nqus dej thiab paug.

Preheating ua ntej txheej - rau txheej txheem ruaj khov

Ua ntej thov PTFE emulsion lossis silicone roj hmab txheej, cov ntaub yuav xav tau maj mam preheating rau qhov kub thiab txias.

1. Preheating tsis

Teem kub: 60 ° C - 80 ° C , me ntsis saum toj no cov dej lwg taw tes kom tsis txhob overly ceev nto ziab ntawm coatings.
Lub sij hawm nyob: feem ntau yog kaum ob vib nas this mus rau ib los yog ob feeb ntawm luv luv infrared los yog cua kub qhov cub - tsuas yog txaus los nqa cov ntaub rau lub hom phiaj kub.

2. Cov lus qhia ua haujlwm ua haujlwm

Siv cov ntaub ntawv ntsuas kub raws li tus qauv, tsis yog qhov cub cua kub. Siv cov ntsuas kub infrared lossis nrog cov ntsuas kub ntsuas rau kev saib xyuas lub sijhawm.
Uniform air flow & circulation - cua kub convection txiav txim kom qhuav efficiency. Uniform cua ceev kom paub meej txawm tias qhov kub thiab txias ntawm cov ntaub dav.
Cov qauv kuaj ua ntej: Cov khoom sib txawv tuaj yeem siv tus neeg sawv cev sib txawv. Siv cov qauv me me thiab ziab lawv ntawm qhov kub sib txawv (105 ° C, 120 ° C, 130 ° C, thiab lwm yam). Saib xyuas qhov decoloration thiab lub zog hloov pauv kom paub meej tias qhov ntsuas kub siab tshaj plaws rau txhua pawg.

Cia Tom qab ziab - Tiv thaiv kom tsis txhob kis kab mob

Cov ntaub qhuav, tshwj xeeb tshaj yog cov ntaub dewaxed, yog hygroscopic thiab yooj yim kis.

Yog tias tsis siv tam sim ntawd, muab khi rau hauv cov hnab ntawv aluminium nrog cov desiccants.
Lwm txoj hauv kev: khaws cia hauv chav ziab nrog qhov kub qis dua 30 ° C thiab txheeb ze av noo qis dua 40%.
Pom zoo siv lub qhov rais: li ntawm 4 mus rau 8 teev tom qab ziab kom zoo tshaj plaws. Tsis tas li ntawd, rov ua kom qhuav ua ntej siv.

Aokai PTFE tip: Rau cov ntawv thov kev ntseeg siab (aerospace composites, high-voltage rwb thaiv tsev), peb pom zoo kom siv cov ntaub tam sim ntawd tom qab ziab los yog hauv 2 teev.
