Cov iav fiber ntau (yav tas los hu ua lus Askiv li iav fiber ntau lossis fiberglass) yog cov khoom siv tsis muaj hlau tsis muaj hlau nrog kev ua haujlwm zoo.Nws muaj ntau yam.Nws qhov zoo yog rwb thaiv tsev zoo, muaj zog tiv thaiv tshav kub, zoo corrosion kuj thiab siab mechanical zog, tab sis nws qhov tsis zoo yog nkig thiab hnav tsis zoo.Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv ntxiv hauv cov khoom sib xyaw, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob thermal, cov khoom siv hluav taws xob thiab lwm yam kev lag luam hauv teb chaws.
Xyoo 2021, lub peev xwm tsim cov iav pob rau hlau kos duab ntawm ntau yam crucibles hauv Suav teb yog 992000 tons, nrog rau xyoo tas los nce ntawm 3.2%, uas tau qeeb qeeb dua li xyoo tas los.Raws li keeb kwm yav dhau los ntawm "ob chav carbon" txoj kev txhim kho lub tswv yim, iav pob kiln lag luam tau ntsib ntau thiab ntau lub zog kaw nyob rau hauv cov nqe lus ntawm cov khoom siv hluav taws xob thiab cov khoom siv raw khoom.
Dab tsi yog fiberglass yarn?
Cov iav fiber ntau xov paj yog ib yam ntawm cov khoom siv tsis zoo uas tsis yog xim hlau nrog kev ua haujlwm zoo.Muaj ntau hom iav fiber ntau yarn.Qhov zoo ntawm cov iav fiber ntau yog cov rwb thaiv tsev zoo, muaj zog tiv taus cua sov, zoo corrosion kuj thiab siab mechanical zog, tab sis qhov tsis zoo yog nkig thiab hnav tsis zoo.Cov iav fiber ntau yog ua los ntawm cov iav pob lossis cov iav khib nyiab los ntawm qhov kub-kub melting, hlau kos duab, winding, weaving thiab lwm yam txheej txheem, Lub cheeb ntawm nws monofilament yog ob peb microns mus rau ntau tshaj 20 meters, uas yog sib npaug rau 1/20-1. / 5 ntawm ib cov plaub hau.Txhua pob ntawm fiber ntau precursor yog tsim los ntawm ntau pua lossis ntau txhiab tus monofilaments.
Lub hom phiaj tseem ceeb ntawm iav fiber ntau yog dab tsi?
Cov iav fiber ntau yog siv los ua cov khoom siv hluav taws xob rwb thaiv tsev, cov khoom siv lim dej, tiv thaiv corrosion, noo noo-pov thawj, rwb thaiv tsev kub, suab rwb thaiv tsev thiab cov ntaub ntawv poob siab, thiab kuj yog cov khoom siv ntxiv.Cov iav fiber ntau yog siv dav dua li lwm hom fibers los tsim cov khoom siv dag zog, iav fiber ntau xov paj los yog cov roj hmab muaj zog, siv zog gypsum thiab cov cement, iav fiber ntau yog coated nrog cov ntaub ntawv organic.Cov iav fiber ntau tuaj yeem txhim kho nws qhov yooj yim thiab tuaj yeem siv los ua cov ntaub ntim khoom, lub qhov rais screen, cov ntaub thaiv phab ntsa, cov ntaub npog, cov khaub ncaws tiv thaiv, hluav taws xob rwb thaiv tsev thiab cov khoom siv suab rwb thaiv tsev.
Dab tsi yog kev faib tawm ntawm iav fiber ntau xov paj?
Twistless roving, twistless roving ntaub (checkered daim ntaub), iav fiber ntau, tws precursor thiab av fiber, iav fiber ntaub, ua ke iav fiber reinforcement, iav fiber ntub xav.
Cov iav fiber ntau ribbon xov paj txhais li cas los ntawm feem ntau 60 yarns ib 100cm?
Qhov no yog cov ntaub ntawv tshwj xeeb ntawm cov khoom, uas txhais tau hais tias muaj 60 xov paj hauv 100 cm.
Yuav ua li cas loj iav fiber yarn?
Rau iav xov paj ua los ntawm iav fiber ntau, ib qho xov paj feem ntau xav tau sizing, thiab filament ob strand yarn tsis tuaj yeem sizing.Cov iav fiber ntau yog nyob rau hauv cov khoom me me.Yog li ntawd, feem ntau ntawm lawv yog sizing nrog qhuav sizing los yog slitting sizing tshuab, thiab ob peb yog sizing nrog ncej warp sizing tshuab.Sizing nrog hmoov txhuv nplej siab, hmoov txhuv nplej siab raws li pawg neeg sawv cev, ntev npaum li tus nqi me me (li 3%) tuaj yeem siv.Yog tias koj siv lub tshuab shaftsizing, koj tuaj yeem siv qee qhov PVA lossis acrylic loj.
Cov ntsiab lus ntawm iav fiber ntau yog dab tsi?
Cov kua qaub tsis kam, hluav taws xob tsis kam thiab cov khoom siv ntawm alkali dawb iav fiber ntau zoo dua li cov nruab nrab alkali.
"Branch" yog ib chav tsev qhia qhov specification ntawm iav fiber.Nws yog tshwj xeeb txhais raws li qhov ntev ntawm 1G iav fiber ntau.360 ceg txhais tau tias 1g iav fiber ntau muaj 360 meters.
Specification thiab qauv piav qhia, piv txwv li: EC5 5-12x1x2S110 yog ply yarn.

Dab tsi yog qhov txawv ntawm nruab nrab alkali iav fiber ntau, uas tsis yog alkali iav fiber ntau thiab siab alkali iav fiber ntau?
Ib txoj hauv kev yooj yim kom paub qhov txawv nruab nrab alkali iav fiber ntau, uas tsis yog alkali iav fiber ntau thiab siab alkali iav fiber ntau yog rub ib lub xov paj fiber ntau los ntawm tes.Feem ntau, cov iav fiber ntau uas tsis yog alkali muaj lub zog txhua yam thiab tsis yooj yim rau tawg, ua raws li nruab nrab alkali iav fiber ntau, thaum siab alkali iav fiber ntau tawg thaum rub maj mam.Raws li kev soj ntsuam ntawm qhov muag liab qab, alkali dawb thiab nruab nrab alkali iav fiber ntau xov paj feem ntau tsis muaj qhov tshwm sim ntawm wool yarn, thaum lub wool xov xwm tshwm sim ntawm siab alkali iav fiber ntau xov paj tshwj xeeb tshaj yog loj, thiab ntau tawg monofilaments prick tawm cov xov paj.
Yuav ua li cas txheeb xyuas qhov zoo ntawm iav fiber ntau yarn?
Cov iav fiber ntau yog ua los ntawm iav los ntawm ntau txoj kev molding hauv lub xeev molten.Nws feem ntau muab faib ua cov iav fiber ntau txuas ntxiv thiab tsis txuas iav fiber ntau.Nruam iav fiber ntau yog nrov nyob rau hauv kev ua lag luam.Feem ntau yog ob yam khoom siv fiber ntau txuas ntxiv ua raws li cov qauv tam sim no hauv Suav teb.Ib qho yog nruab nrab alkali iav fiber, code npe C;Ib qho yog alkali dawb iav fiber, code npe E. Qhov txawv ntawm lawv yog cov ntsiab lus ntawm alkali hlau oxides.(12 ± 0.5)% rau nruab nrab alkali iav fiber ntau thiab <0.5% rau non alkali iav fiber ntau.Kuj tseem muaj cov khoom tsis zoo ntawm cov iav fiber ntau hauv khw.Feem ntau hu ua siab alkali iav fiber ntau.Cov ntsiab lus ntawm alkali hlau oxides yog ntau tshaj 14%.Cov khoom siv raw rau kev tsim khoom yog tawg iav los yog iav fwj.Hom iav fiber ntau no muaj cov dej tsis zoo, tsis muaj zog txhua yam thiab tsis tshua muaj hluav taws xob rwb thaiv tsev.Nws tsis raug tso cai los tsim cov khoom raws li kev cai hauv tebchaws.
Feem ntau tsim nyog nruab nrab alkali thiab tsis alkali iav fiber ntau cov khoom lag luam yuav tsum tau nruj nreem qhwv ntawm cov xov paj.Txhua lub raj xov paj yog cim nrog tus lej, tus lej xov tooj thiab qib, thiab daim ntawv pov thawj tshuaj xyuas cov khoom yuav tsum muab rau hauv lub thawv ntim khoom.Daim ntawv pov thawj tshuaj xyuas cov khoom muaj xws li:
1. Lub npe ntawm cov chaw tsim khoom;
2. Code thiab qib ntawm cov khoom;
3. Tus lej ntawm tus qauv no;
4. Stamp lub foob tshwj xeeb rau kev soj ntsuam zoo;
5. Net nyhav;
6. Lub thawv ntim khoom yuav tsum muaj lub Hoobkas lub npe, cov khoom lag luam thiab qib, tus lej qauv, qhov hnyav hnyav, hnub tsim khoom thiab tus lej batch, thiab lwm yam.
Yuav ua li cas rov qab siv cov iav fiber ntau pov tseg txhob lo lo ntxhuav thiab xov paj?
Tom qab tawg, cov iav khib nyiab feem ntau tuaj yeem siv los ua raw khoom rau cov khoom iav.Qhov teeb meem ntawm txawv teb chaws teeb meem / wetting agent residue yuav tsum tau daws.Cov xov paj khib nyiab tuaj yeem siv los ua cov khoom siv iav fiber ntau, xws li kev xav, FRP, pobzeb, thiab lwm yam.
Yuav ua li cas kom tsis txhob muaj kab mob ua haujlwm tom qab kev sib cuag nrog iav fiber ntau ntev?
Kev ua haujlwm ntau lawm yuav tsum hnav cov qhov ncauj qhov ntswg, hnab looj tes thiab lub tes tsho kom tsis txhob muaj kev sib cuag ntawm daim tawv nqaij ncaj qha nrog cov iav fiber ntau.
