Cov iav fiber (yav tas los hu ua lus Askiv hu ua iav fiber lossis fiberglass) yog cov khoom siv inorganic uas tsis yog hlau nrog kev ua tau zoo heev. Nws muaj ntau yam. Nws qhov zoo yog kev rwb thaiv tsev zoo, tiv taus cua sov zoo, tiv taus corrosion zoo thiab lub zog kho tshuab siab, tab sis nws qhov tsis zoo yog brittle thiab tsis hnav tsis kam. Cov iav fiber feem ntau yog siv ua cov khoom siv txhawb nqa hauv cov khoom sib xyaw, cov khoom siv rwb thaiv tsev hluav taws xob thiab cov khoom siv rwb thaiv tsev thermal, cov khoom siv hluav taws xob thiab lwm yam kev lag luam hauv tebchaws.
Xyoo 2021, lub peev xwm tsim cov pob iav rau kev kos hlau ntawm ntau yam crucibles hauv Suav teb yog 992000 tons, nrog rau kev nce txhua xyoo ntawm 3.2%, uas qeeb dua li xyoo tas los. Nyob rau hauv keeb kwm yav dhau los ntawm "ob chav carbon" txoj kev tsim kho, cov lag luam pob iav kiln tab tom ntsib ntau dua thiab ntau dua kev kaw ntawm kev muab hluav taws xob thiab cov nqi khoom siv raw.
Cov xov fiberglass yog dab tsi?
Cov xov iav fiber yog ib hom khoom siv inorganic uas tsis yog hlau uas muaj kev ua tau zoo heev. Muaj ntau hom xov iav fiber. Qhov zoo ntawm cov xov iav fiber yog kev rwb thaiv tsev zoo, tiv taus cua sov tau zoo, tiv taus corrosion tau zoo thiab muaj zog kho tshuab siab, tab sis qhov tsis zoo yog qhov tsis zoo thiab tsis hnav tsis tau zoo. Cov xov iav fiber yog ua los ntawm pob iav lossis pov tseg iav los ntawm kev yaj kub siab, kos duab hlau, winding, weaving thiab lwm yam txheej txheem, Lub cheeb ntawm nws monofilament yog ntau microns txog ntau dua 20 meters, uas yog sib npaug rau 1 / 20-1 / 5 ntawm ib txoj plaub hau. Txhua pob ntawm cov khoom siv fiber ua ntej yog tsim los ntawm ntau pua lossis txawm tias ntau txhiab monofilaments.
Lub hom phiaj tseem ceeb ntawm cov iav fiber yarn yog dab tsi?
Cov xov paj iav fiber feem ntau yog siv ua cov ntaub ntawv rwb thaiv hluav taws xob, cov ntaub ntawv lim dej hauv kev lag luam, tiv thaiv xeb, tiv thaiv dej noo, rwb thaiv cua sov, rwb thaiv suab thiab cov ntaub ntawv nqus kev co, thiab tseem yog cov ntaub ntawv txhawb nqa. Cov xov paj iav fiber yog siv dav dua li lwm hom fibers los tsim cov yas txhawb nqa, cov xov paj iav fiber lossis cov roj hmab txhawb nqa, cov gypsum txhawb nqa thiab cov cement txhawb nqa. Cov xov paj iav fiber yog coated nrog cov ntaub ntawv organic. Cov iav fiber tuaj yeem txhim kho nws qhov kev ywj pheej thiab tuaj yeem siv los ua daim ntaub ntim khoom, daim ntaub thaiv qhov rai, daim ntaub phab ntsa, daim ntaub npog, khaub ncaws tiv thaiv, rwb thaiv hluav taws xob thiab cov ntaub ntawv rwb thaiv suab.
Cov kev faib tawm ntawm cov iav fiber ntau yog dab tsi?
Kev sib ntswg tsis sib ntswg, daim ntaub sib ntswg tsis sib ntswg (daim ntaub checkered), iav fiber ntau, cov khoom siv ua ntej thiab cov fiber hauv av, daim ntaub iav fiber, kev sib xyaw ua ke ntawm iav fiber, iav fiber ntub.
Cov xov paj iav fiber txhais li cas los ntawm feem ntau 60 xov paj ib 100cm?
Nov yog cov ntaub ntawv qhia txog cov khoom, uas txhais tau tias muaj 60 xov paj hauv 100 cm.
Yuav ua li cas kom loj npaum li cas ntawm cov iav fiber?
Rau cov xov iav ua los ntawm cov iav fiber, feem ntau cov xov ib leeg xav tau qhov loj me, thiab cov xov filament ob txoj hlua tsis tuaj yeem ua qhov loj me. Cov ntaub iav fiber yog ua cov khoom me me. Yog li ntawd, feem ntau ntawm lawv yog qhov loj me nrog lub tshuab txiav qhov loj me qhuav lossis lub tshuab txiav qhov loj me, thiab ob peb qhov loj me nrog lub tshuab txiav qhov loj me. Kev txiav qhov loj me nrog cov hmoov txhuv nplej siab, hmoov txhuv nplej siab ua tus neeg sawv cev, tsuav yog siv qhov loj me me (kwv yees li 3%). Yog tias koj siv lub tshuab txiav qhov loj me, koj tuaj yeem siv qee qhov PVA lossis acrylic loj.
Cov lus hais txog cov iav fiber ntau yog dab tsi?
Qhov ua rau acid tsis kam, hluav taws xob tsis kam thiab cov khoom siv kho tshuab ntawm alkali dawb iav fiber zoo dua li cov alkali nruab nrab.
"Ceg" yog ib chav ntsuas qhia txog qhov ntev ntawm cov iav fiber. Nws yog txhais tshwj xeeb tias yog qhov ntev ntawm 1G iav fiber. 360 ceg txhais tau tias 1g iav fiber muaj 360 meters.
Cov lus qhia tshwj xeeb thiab cov qauv piav qhia, piv txwv li: EC5 5-12x1x2S110 yog xov paj rwb.

Qhov txawv ntawm cov iav fiber alkali nruab nrab, cov iav fiber tsis alkali thiab cov iav fiber alkali siab yog dab tsi?
Ib txoj hauv kev yooj yim los paub qhov txawv ntawm cov iav fiber alkali nruab nrab, cov iav fiber tsis alkali thiab cov iav fiber alkali siab yog rub ib txoj xov fiber los ntawm tes. Feem ntau, cov iav fiber tsis alkali muaj lub zog kho tshuab siab thiab tsis yooj yim tawg, ua raws li cov iav fiber alkali nruab nrab, thaum cov iav fiber alkali siab tawg thaum rub maj mam. Raws li qhov muag pom, cov iav fiber alkali tsis muaj alkali thiab nruab nrab alkali feem ntau tsis muaj qhov tshwm sim ntawm cov xov paj ntaub plaub, thaum cov xov paj ntaub plaub ntawm cov iav fiber alkali siab yog qhov hnyav heev, thiab ntau cov monofilaments tawg tawm cov ceg xov paj.
Yuav ua li cas txheeb xyuas qhov zoo ntawm cov iav fiber yarn?
Cov iav fiber yog ua los ntawm iav los ntawm ntau txoj kev molding hauv lub xeev molten. Nws feem ntau muab faib ua cov iav fiber tas mus li thiab cov iav fiber tsis tas mus li. Cov iav fiber tas mus li nrov dua hauv kev ua lag luam. Muaj ob hom khoom iav fiber tas mus li tsim raws li cov qauv tam sim no hauv Suav teb. Ib qho yog cov iav fiber nruab nrab alkali, codenamed C; Ib qho yog cov iav fiber tsis muaj alkali, codenamed E. Qhov sib txawv tseem ceeb ntawm lawv yog cov ntsiab lus ntawm alkali hlau oxides. (12 ± 0.5)% rau cov iav fiber nruab nrab alkali thiab <0.5% rau cov iav fiber tsis muaj alkali. Kuj tseem muaj cov khoom iav fiber tsis yog tus qauv hauv kev ua lag luam. Feem ntau hu ua alkali iav fiber siab. Cov ntsiab lus ntawm alkali hlau oxides yog ntau dua 14%. Cov khoom siv raw rau kev tsim khoom yog cov iav tiaj tiaj lossis lub raj mis iav. Hom iav fiber no muaj kev tiv thaiv dej tsis zoo, lub zog kho tshuab qis thiab kev rwb thaiv hluav taws xob qis. Nws tsis raug tso cai tsim cov khoom raws li cov cai hauv tebchaws.
Cov khoom siv fiber iav uas tsim nyog rau alkali thiab tsis alkali yuav tsum tau khi kom nruj rau ntawm lub raj xov. Txhua lub raj xov muaj tus lej, tus lej xov thiab qib cim, thiab daim ntawv pov thawj tshuaj xyuas khoom yuav tsum muab tso rau hauv lub thawv ntim khoom. Daim ntawv pov thawj tshuaj xyuas khoom suav nrog:
1. Lub npe ntawm tus neeg tsim khoom;
2. Cov lej thiab qib ntawm cov khoom;
3. Tus lej ntawm tus qauv no;
4. Muab lub cim tshwj xeeb rau kev tshuaj xyuas zoo;
5. Qhov hnyav tag nrho;
6. Lub thawv ntim khoom yuav tsum muaj lub npe Hoobkas, tus lej khoom thiab qib, tus lej txheem, qhov hnyav tag nrho, hnub tsim khoom thiab tus lej pawg, thiab lwm yam.
Yuav ua li cas rov siv dua cov iav fiber pov tseg silk thiab xov paj?
Tom qab tawg lawm, cov iav pov tseg feem ntau siv tau ua cov khoom siv raw rau cov khoom iav. Qhov teeb meem ntawm cov khoom txawv teb chaws / cov khoom seem ntub dej yuav tsum tau daws. Cov xov pov tseg siv tau ua cov khoom siv iav dav dav, xws li cov ntaub, FRP, vuas, thiab lwm yam.
Yuav ua li cas kom tsis txhob muaj kab mob hauv kev ua haujlwm tom qab kev sib cuag ntev nrog cov iav fiber ntau?
Cov haujlwm tsim khoom yuav tsum hnav lub ntsej muag tiv thaiv, hnab looj tes thiab tes tsho kom tsis txhob kov daim tawv nqaij ncaj qha nrog cov xov iav fiber.
