Cov txheej txheem ntau lawm thiab tsib yam ntxwv ntawm iav fiber ntau

IB, iav fiber ntau txheej txheem

Fibers iav, ib qho kev txhawb nqa Fibra de vidrio compuestathiab cov khoom siv hlau hloov.Txoj kab uas hla ntawm cov monofilament yog ob peb microns mus rau nees nkaum microns, uas yog sib npaug rau 1/20-1/5 ntawm cov plaub hau, thiab txhua pob ntawm fiber ntau strands yog tsim los ntawm ntau pua lossis ntau txhiab tus monofilaments.

Fiberglass preg muaj cov yam ntxwv ntawm cov khoom tsis-combustibility, corrosion kuj, rwb thaiv tsev kub, zoo suab rwb thaiv tsev, siab tensile zog, zoo hluav taws xob rwb thaiv tsev, thiab lwm yam. Nws muaj ntau yam kev siv thiab yog dav siv nyob rau hauv kev tsim kho, tsheb, nkoj, tshuaj. pipelines, rail transit, cua zog thiab lwm yam kev nthuav dav daim ntawv thov prospects.

Muaj ob hom iav fiber ntau cov txheej txheem: ob-lub sij hawm txoj kev - crucible drawing method, ib tug forming - pas dej ua ke kiln drawing method.

Txoj kev kos duab crucible muaj ntau yam txheej txheem.Ua ntej, cov khoom siv iav yog melted rau hauv cov khob iav ntawm qhov kub thiab txias, thiab tom qab ntawd cov khob iav yog yaj rau zaum ob, thiab tom qab ntawd kos rau ntawm qhov kub ceev kom ua.rov.Cov txheej txheem no muaj ntau yam kev tsis zoo xws li kev siv hluav taws xob siab, cov txheej txheem molding tsis ruaj khov, thiab kev ua haujlwm tsawg, thiab yog ib txwm tshem tawm los ntawm cov tuam txhab loj iav fiber ntau.

Lub pas dej kiln kev kos duab melts raw cov ntaub ntawv xws li pyrophyllite rau hauv cov iav tov nyob rau hauv lub kiln, tshem tawm cov pa npuas thiab thauj mus rau ib tug ntxeem tau bushing los ntawm ib txoj kev, thiab rub nws mus rau hauv ib tug iav fiber strand ntawm ib tug ceev ceev.Lub kiln tuaj yeem txuas ntau pua bushings los ntawm ntau txoj hauv kev rau kev tsim khoom ib txhij.Cov txheej txheem no yooj yim, txuag hluav taws xob thiab txo qis, ruaj khov hauv molding, high-efficiency thiab high-yield, thiab yog yooj yim rau loj-scale tag nrho automated ntau lawm.Nws tau dhau los ua txheej txheem kev tsim khoom thoob ntiaj teb.Fiberglass quoins tsim los ntawm cov txheej txheem no rau ntau tshaj 90% ntawm lub ntiaj teb tso zis.

二 、 Lub tsib yam ntxwv ntawm iav fiber ntau

1. Kev nyab xeeb thiab kev tiv thaiv ib puag ncig, tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm

Cov iav fiber ntau muaj zog tensile zog, tsis muaj wrinkle, anti-vulcanization, tsis haus luam yeeb, halogen-dawb, tsis muaj tshuaj lom, ntshiab oxygen, tsis-combustible, thiab zoo insulating zog.Tom qab kho nrog silicone, nws txoj kev nyab xeeb thiab kev ua haujlwm ib puag ncig tuaj yeem txhim kho ntxiv.Ua haujlwm zoo tiv thaiv tib neeg kev noj qab haus huv ntawm cov neeg ua haujlwm thiab txo qhov tshwm sim ntawm cov kab mob ua haujlwm.Tsis zoo li cov khoom lag luam asbestos, nws muaj kev phom sij heev rau tib neeg thiab ib puag ncig.

2.Excellent kub kuj

Qhov saum npoo ntawmfiberglass thermal rwb thaiv tsev muaj ob qho tib si "organic pawg" thiab "cov qauv inorganic".Qhov tshwj xeeb muaj pes tsawg leeg thiab cov qauv molecular tso cai rau nws los ua ke cov khoom ntawm cov organic teeb meem nrog kev ua haujlwm ntawm inorganic teeb meem.Piv nrog rau lwm cov ntaub ntawv polymer, nws sawv tawm rau nws qhov kub thiab txias.Silicon-oxygen (Si-O) daim ntawv cog lus yog cov qauv saw tseem ceeb, thiab daim ntawv cog lus lub zog ntawm CC daim ntawv cog lus yog 82.6 kcal / g thiab lub zog ntawm Si-O daim ntawv cog lus yog 121 kcal / g hauv silicone resin, yog li Lub thermal stability yog siab, thiab cov tshuaj bonds ntawm molecules tsis tawg los yog disintegrate nyob rau hauv high kub (los yog hluav taws xob raug).Silicone tsis yog tsuas yog tiv taus qhov kub thiab txias tab sis kuj tseem kub, thiab tuaj yeem siv rau hauv qhov kub thiab txias.Nws tsis hloov nrog qhov kub thiab txias, xws li tshuaj lom neeg lossis lub cev-mechanical zog.

3.Anti-splash, ntau yam kev tiv thaiv

Hauv kev lag luam smelting, qhov kub ntawm qhov nruab nrab hauv qhov cub hluav taws xob yog qhov siab heev, thiab qhov kub thiab txias spatters tau yooj yim tsim (xws li hauv kev lag luam vuam hluav taws xob).Tom qab txias thiab solidifying, slag cov ntaub ntawv ntawm cov yeeb nkab los yog cable, uas hardens cov roj hmab rau txheej txheej ntawm cov yeeb nkab los yog cable thiab ua rau nkig puas.Nyob rau hauv lem, cov khoom uas tsis muaj kev tiv thaiv thiab cables yuav puas.Tom qab siv ntau yam silicone-coatedfiberglass lub tes tsho, ntau yam kev tiv thaiv kev nyab xeeb tuaj yeem ua tiav thiab qhov kub siab melting ntawm molten hlau, tooj liab thiab txhuas tuaj yeem tiv thaiv tau zoo.txaws dej kom tsis txhob muaj kev puas tsuaj rau cov cables thiab khoom siv.

4. Thaum tshav kub kub rwb thaiv tsev, txuag hluav taws xob, tiv thaiv hluav taws xob

Nyob rau hauv qhov chaw ua haujlwm kub kub, ntau cov kav dej, li qub lossis cov khoom siv muaj qhov kub thiab txias.Kev kub hnyiab lossis kub poob yuav tshwm sim yog tias tsis npog nrog cov khoom tiv thaiv.Fiberglass muaj thermal stability zoo dua li lwm cov ntaub ntawv polymer, thiab tiv taus hluav taws xob thiab thermal rwb thaiv tsev, tiv thaiv kev sib tsoo, txo kev siv hluav taws xob thiab tiv thaiv kev hloov hluav taws xob ncaj qha los ntawm nruab nrab hauv cov yeeb nkab mus rau thaj tsam ib puag ncig.Ib puag ncig overheats lub rooj cob qhia, uas txuag cov nqi cua txias.

5.Moisture-pov thawj, roj-pov thawj, huab cua-pov thawj, muaj kuab paug-pov thawj, ua kom lub neej ntev ntawm cov khoom siv

Cov iav fiber ntau muaj cov tshuaj lom neeg ruaj khov.Silicone yuav tsis hnov ​​​​mob nrog roj, dej, kua qaub thiab alkali thiab lwm yam. Ntawm qhov kub ntawm 260 ° C, nws tuaj yeem siv tau ntev yam tsis muaj kev laus.Kev pab lub neej ntawm fiberglass waterproofnyob rau hauv ib puag ncig ntuj tuaj yeem ncav cuag ntau xyoo lawm.Hauv qhov no, nws tuaj yeem tiv thaiv cov kav dej, cables thiab cov cuab yeej siv tau zoo thiab siv sijhawm ntev heev.
