Daim ntawv fiberglass yog dab tsi?

Dab tsi yogfiberglass ntawv? Cov ntawv iav fiber ntau yog cov ntawv ua lag luam, feem ntau yog siv los ua cov khoom siv lim dej, suab- cov khoom nqus dej, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob. Nws yog ib daim ntawv ua los ntawm cov iav zoo fibers thiab nta cov nplaim hluav taws kub retardancy, muaj zog tshuaj tiv thaiv, thiab zoo seem stability.

Nws yog ib daim ntawv nyias nyias ua los ntawm cov iav fiber ntau. Nws muaj qhov ruaj khov zoo, muaj zog tshuaj lom neeg, muaj zog tiv thaiv huab cua, thiab tsis zoo -flammable. Nws tuaj yeem tsim los ntawm 100% iav fibers (inch hauv qab 0.3 ~ 0.5μm, feem ntau yog tsim los ntawm silica), maj mam sib tsoo, nrog rau cov nplaum ntxiv, los yog ntxiv ntawm qee cov tshuaj ntoo pulp, ntawm lub tshuab ntawv plaub los yog lub tog raj kheej. Silica gel lossis colloidal bauxite kuj tuaj yeem muab ntxiv los txhim kho lub zog. Hom ntawv no, siv rau hauv cov ntaub ntawv thermal rwb thaiv tsev, cov ntaub ntawv hluav taws xob rwb thaiv tsev, thiab ua cov khoom siv ntxiv rau cov khoom siv hluavtaws, txawv me ntsis ntawm cov ntaub ntawv zoo tib yam. Nws yog tsim los ntawm 100% iav fiber ntau (iav fiber ntau daim ntawv yog tsim los ntawm silica, nrog ib txoj kab uas hla ntawm 0.3-0.5 μm los yog tsawg dua), maj mam ntaus, nrog rau ntxiv cov nplaum, los yog tej zaum ib feem ntawm cov tshuaj ntoo pulp, thiab ces tsim nyob rau hauv ib tug fourdrinier los yog lub tog raj kheej ntawv tshuab. Silica gel lossis colloidal alumina kuj tuaj yeem muab ntxiv los txhim kho daim ntawv lub zog.

Cov txheej txheem ntawm cov ntawv iav fiber ntau (los yog iav fiber ntau cua lim ntawv) yog qhov yooj yim dua li cov txheej txheem papermaking. Qhov no yog vim iav fiber ntau tsis tas yuav ntaus, tsuas yog dispersion. Tsis tas li ntawd, nias tsis tas yuav tsum tau ua thaum ua ntawv, txo cov kauj ruam thiab txuag lub zog.

Cov txheej txheem ntws yog raws li nram no: iav fiber ntau → dispersion → slurry cia tank → slurry twj tso kua mis → ua ntej - slurry tank → slurry txias tank → yias → slurry flushing tank → slurry twj tso kua mis → slurry stabilizing tank → headbox → xaim seem → slurry chav → winding. Fiberglass feem ntau yog siv los ua cov khoom siv txhawb zog hauv cov khoom sib xyaw, nrog rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov rooj sib tham, thiab lwm yam kev siv hauv ntau yam kev lag luam hauv lub tebchaws. Thaum siv los ua cov khoom siv txhawb zog rau cov yas yas, iav fiber ntau yog cov yam ntxwv ntawm nws lub zog tensile siab. Yog li, dab tsi yog iav fiber ntau ua los ntawm? Nws cov yam ntxwv yog dab tsi? Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv txhawb zog hauv cov ntaub ntawv sib xyaw, nrog rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov rooj sib tham hauv Circuit Court, thiab lwm yam kev siv hauv ntau yam kev lag luam hauv lub tebchaws. Thaum siv los ua cov khoom siv txhawb zog rau cov yas yas, iav fiber ntau yog cov yam ntxwv ntawm nws lub zog tensile siab. Yog li dab tsi yog iav fiber ntau ua los ntawm? Nws cov yam ntxwv yog dab tsi?

Fiberglass tuaj yeem muab faib los ntawm cov duab thiab ntev mus rau hauv fiber ntau txuas ntxiv, ruaj -ntev fiber ntau, thiab iav ntaub plaub; thiab los ntawm iav muaj nyob rau hauv alkali-dawb, tshuaj-resistant, siab-alkali, nruab nrab-alkali, siab- zog, siab- elasticity modulus, thiab alkali-resistant (alkali-}resistant) iav fibers, thiab lwm yam.

Cov ntaub ntawv tseem ceeb rau kev tsim cov iav fiber ntau yog: quartz xuab zeb, alumina thiab pyrophyllite, limestone, dolomite, boric acid, dej qab zib tshauv, mirabilite, fluorite, thiab lwm yam. Cov txheej txheem ntau lawm tau muab faib ua ob pawg: ib qho yog los tsim cov fibers ncaj qha los ntawm molten iav; lwm yam yog thawj daim iav molten rau hauv iav spheres los yog rods nrog ib txoj kab uas hla ntawm 20mm, thiab ces remelt lawv los ntawm ntau txoj kev los tsim zoo fibers nrog ib txoj kab uas hla ntawm 3-80μm. Infinitely ntev fibers kos mechanically los ntawm platinum alloy daim hlau hu ua nruam iav fibers, feem ntau hu ua ntev fibers. Tsis yog- cov fibers txuas ntxiv uas tsim los ntawm cov chais lossis airflow yog hu ua ntev iav fibers, feem ntau hu ua luv fibers.

Fiberglass tau muab faib ua ntau qib raws li lawv muaj pes tsawg leeg, cov khoom, thiab kev siv. Raws li tus qauv specifications, Qib E iav fiber ntau yog siv rau hauv cov khoom siv hluav taws xob rwb thaiv tsev; Qib S yog fiber ntau tshwj xeeb. Cov iav siv los tsim cov iav fiber ntau txawv ntawm cov iav siv hauv lwm cov khoom iav.

Cov yam ntxwv ntawm iav fiber ntau yog dab tsi?

1. Cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob kub zoo.

2. High tensile lub zog, zoo tshav kub tsis kam, thiab corrosion kuj.

3. Tsis yog -flammable thiab nrog zoo heev tshuaj stability.

Fiberglass yarn yog ib qho kev ua haujlwm siab -kev ua haujlwm inorganic non-cov khoom siv hlau nrog ntau yam. Nws qhov zoo muaj xws li rwb thaiv tsev zoo, muaj zog cua sov, zoo corrosion kuj, thiab siab mechanical zog. Txawm li cas los xij, nws qhov tsis zoo muaj xws li brittleness thiab tsis zoo abrasion tsis kam. Cov iav fiber ntau yog tsim los ntawm cov iav spheres lossis cov iav khib nyiab los ntawm kev kub siab -kub melting, kos duab, winding, thiab weaving txheej txheem. Txoj kab uas hla ntawm nws ib leeg filaments ranges los ntawm ob peb micrometers mus rau ntau tshaj nees nkaum micrometers, sib npaug li ntawm 1/20 txog 1/5 ntawm txoj kab uas hla ntawm tib neeg cov plaub hau. Txhua pob ntawm fiber ntau muaj ntau pua lossis ntau txhiab tus tib filaments. Fiberglass yarn feem ntau yog siv los ua cov khoom siv hluav taws xob, cov khoom siv pom, thiab cov khoom siv rau kev tiv thaiv corrosion, noo noo tsis kam, rwb thaiv tsev kub, suab rwb thaiv tsev, thiab kev poob siab. Nws kuj tseem siv tau los ua cov khoom siv ntxiv. Kev siv ntawm fiberglass yarn yog dav dav dua li lwm hom fibers. Nws yog siv los tsim cov yas yas, lossis cov roj hmab ntxiv, gypsum, thiab cov khoom cement. Txheej fiberglass yarn nrog cov ntaub ntawv organic tuaj yeem txhim kho nws txoj kev yooj yim, ua rau nws tsim nyog rau ntim cov ntaub, qhov rais cov ntxaij vab tshaus, phab ntsa npog, npog ntaub, tiv thaiv khaub ncaws, thiab hluav taws xob rwb thaiv tsev thiab suab rwb thaiv tsev cov ntaub ntawv.

Cov ntaub ntawv saum toj no hais txog dab tsi fiberglass yog thiab nws cov yam ntxwv tau qhia. Peb cia siab tias nws tau pab kom nkag siab txog fiberglass.
