Daim ntawv fiberglass yog dab tsi?

Fiberglass ntawvyog cov ntawv muaj feem ntau siv los ua cov khoom siv lim dej, suab-cov khoom siv nqus, 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 ua los ntawm cov iav fibers zoo. 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 qhov sib ntxiv ntawm cov nplaum, los yog ib feem ntawm 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 yog siv rau hauv cov ntaub ntawv thermal rwb thaiv tsev, cov khoom siv hluav taws xob rwb thaiv tsev, thiab ua cov khoom siv ntxiv rau cov khoom siv hluavtaws.

 

Cov txheej txheem tsim ntawm daim ntawv no txawv me ntsis los ntawm kev ua ntawv zoo tib yam. Nws siv 100% iav fiber ntau (iav fiber ntau ntawv yog tsim los ntawm silica, nrog ib txoj kab uas hla ntawm tsawg tshaj li 0.3-0.5 μm), maj mam ntaus, thiab ces tov nrog nplaum, los yog nrog ib co tshuaj ntoo pulp. Tom qab ntawd nws yog tsim los ntawm lub tshuab plaub hau los yog lub tog raj kheej. Silica gel lossis colloidal alumina kuj tuaj yeem muab ntxiv los txhim kho lub zog ntawm daim ntawv tiav.

 

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 → Pre- slurry tank → Slurry txias tank → Settling yias → Slurry flushing tank → Slurry twj tso kua mis → Slurry stabilizing tank → Headbox → Wire packing l

 

Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv ntxiv 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?

 

Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv ntxiv 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?

 

Cov iav fiber ntau yog dab tsi?

 

Cov iav fiber ntau tuaj yeem muab faib los ntawm cov duab thiab ntev rau hauv fiber ntau txuas ntxiv, ruaj khov -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-lub zog, siab-elastic 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.

 

Cov iav fiber ntau tau muab faib ua cov qib sib txawv raws li nws qhov muaj pes tsawg leeg, cov khoom siv, 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.

 

iav fiber ntau xov paj yog ib lub siab -kev ua tau zoo inorganic non-cov khoom siv hlau nrog ntau 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 lim dej, los tiv thaiv - corrosion, ya raws- pov thawj, rwb thaiv tsev kub, suab rwb thaiv tsev, thiab cov khoom siv poob siab. Nws kuj tseem siv tau los ua cov khoom siv ntxiv. Kev siv cov xov paj fiberglass yog dav dav dua li ntawm lwm hom fibers. Nws yog siv los tsim cov khoom lag luam xws li cov yas muaj zog, cov roj hmab muaj zog, cov gypsum reinforced, thiab cov cement ntxiv. Txheej fiberglass yarn nrog cov ntaub ntawv organic tuaj yeem txhim kho nws qhov yooj yim thiab ua rau nws mus rau hauv cov ntaub ntim khoom, cov ntxaij vab tshaus qhov rais, cov ntaub thaiv phab ntsa, cov ntaub npog, cov khaub ncaws tiv thaiv, thiab hluav taws xob rwb thaiv tsev thiab cov ntaub ntawv suab rwb thaiv tsev.
