Cov iav fiber ntau (yav dhau los paub ua lus Askiv li iav fiber ntau lossis cov fiberglass) yog cov khoom siv tsis zoo nkauj uas tsis yog xim hlau nrog kev ua tau zoo heev. Nws muaj ntau yam. Nws cov txiaj ntsig yog rwb thaiv tsev zoo, muaj zog kub tiv thaiv, zoo corrosion tsis kam thiab muaj kev cuam tshuam zoo yog nkig thiab hnav tsis zoo. Cov iav fiber ntau feem ntau yog siv los ua cov khoom siv uas siv hluav taws xob thiab hluav taws xob rwb thaiv tsev cov khoom siv, hluav taws xob ua ntu zus thiab lwm lub teb ntawm kev lag luam hauv tebchaws.
Xyoo 2021, cov khoom muaj peev ntau lawm ntawm cov iav pob rau cov hlau kos duab ntawm cov neeg tawv ntoo muaj zog ntawm 3.2%, uas tau qeeb qeeb tshaj li xyoo tas los. Nyob rau hauv lub keeb kwm yav dhau los ntawm "siv ob zaug ntawm cov phiaj xwm"
Dab tsi yog fiberglass paj?
Cov xov tooj iav fiber yog ib hom inorganic cov khoom siv tsis yog xim hlau nrog kev ua tau zoo heev. Muaj ntau ntau yam xov tooj fiber ntau. Qhov zoo ntawm cov xov tooj fiber ntau yog cov rwb thaiv tsev zoo, muaj zog tiv thaiv hluav taws xob, tab sis qhov tsis zoo yog nkig thiab hnav tsis zoo. Iav Xov Xwm Fiber Ntau yog tsim los ntawm iav pob los yog khib nyiab iav los ntawm kev kub siab, winding kos duab, uas cov txheej txheem ntawm ntau tshaj 20 metres, uas yog sib npaug rau 1 / 20-1 / 5 ntawm plaub hau. Txhua ntu ntawm fiber ua ntej precursor yog tsim ntawm ntau pua lossis txawm tias ntau txhiab ntawm monofilaments.
Lub hom phiaj tseem ceeb ntawm cov iav fiber ntau?
Cov xov tooj muaj fiber ntau yog siv hluav taws xob cov ntaub ntawv hluav taws xob, cov ntaub ntawv lim dej, cov khoom siv lim dej ua kom sov, thiab tseem muaj cov ntaub ntawv kev ua poob siab. Cov xov tooj iav fiber ntau dua li lwm cov fiberforced plastics, cov roj hmab fiber ntau lossis txhawb nqa cov roj hmab, cov xov paj fiber ntau yog coated nrog cov ntaub ntawv organic. Cov fiber ntau tuaj yeem txhim kho nws cov ntaub pua tsev, cov ntaub pua rooj, phab ntsa, rwb thaiv tsev phab ntsa thiab rwb thaiv tsev rwb thaiv tsev.
Dab tsi yog cov kev faib tawm ntawm cov xov paj fiber ntau?
Lub ntsej muag tsis sib haum, cov ntaub qhwv ntsej muag, cov iav fiber ntau, ua kom muaj fiber ntau, ua ke iav fiber ntau, ua ke lub khob fiber ntau ntxiv, khob iav fiber ntau muaj.
Dab tsi yog khob fiber ribbon yarn txhais tau los ntawm feem ntau 60 yarns ib 100cm?
Qhov no yog cov khoom lag luam tshwj xeeb cov ntaub ntawv, uas txhais tau tias muaj 60 yarn hauv 100 cm.
Yuav ua li cas kom loj iav fiber ntau xov?
Txog cov xov paj ua los ntawm cov iav fiber ntau, ib qho xov ib leeg feem ntau xav tau sizing, thiab filament ob chav strand xov tsis tuaj yeem yog sizing. Iav Fiber Cab yog hauv cov khoom me me. Yog li no, feem ntau ntawm lawv yog sizing nrog qhuav sizing lossis slitting sizing tshuab, thiab ob peb yog sizing nrog Ncej ceeb toom tshuab. SIZING nrog cov hmoov txhuv nplej siab, cov hmoov txhuv nplej siab ua tus sawv cev pawg, ntev npaum li tus nqi me me (li 3%) tuaj yeem siv. Yog tias koj siv lub tshuab sizing, koj tuaj yeem siv qee pva lossis acrylic loj.
Dab tsi yog cov lus ntawm cov xov paj fiber ntau?
Cov kua qaub tsis kam, hluav taws xob tsis kam thiab cov cuab yeej siv tshuab ntawm alkali dawb fiber ntau yog qhov zoo dua li cov alkali.
"Ceg" yog ib chav ntsuas qhov tseeb ntawm cov iav fiber ntau. Nws yog tshwj xeeb txhais tau tias yog qhov ntev ntawm 1g iav fiber ntau. 360 ceg txhais tau tias 1g iav fiber muaj 360 meters.
Cov lus qhia tshwj xeeb thiab qauv piav qhia, piv txwv: EC5 5-12x1x2S110 yog ply yarn.

Dab tsi yog qhov sib txawv ntawm nruab nrab cov iav alkali iav fiber ntau, tsis yog alkali iav fiber ntau thiab siab alkali iav fiber ntau?
Ib txoj hauv kev yooj yim kom paub qhov txawv nruab nrab cov kua mis alkali, tsis alkali iav fiber ntau yog kom rub tau ib lub xovtooj ib leeg ntawm tes. Feem ntau, tsis alkali iav fiber muaj cov tshuab zog muaj zog thiab tsis yooj yim los ua kom tawg, ua raws li cov iav alkali uas tsis sib xws thaum rub maj mam muab. Raws li kev soj ntsuam qhov muag pom kev zoo, cov alkali dawb thiab nruab nrab cov xov paj fiber ntau cov xov paj
Yuav ua li cas txheeb xyuas qhov zoo ntawm cov iav fiber ntau?
Iav Fiber yog ua los ntawm iav los ntawm ntau txoj kev molding hauv Molten State. Nws feem ntau muab faib ua cov iav fiber ntau thiab cov iav tsis zoo. Nruam cov iav fiber ntau yog nrov dua hauv kev ua lag luam. Muaj ntau yam ntawm cov iav txuas ntxiv cov khoom siv fiber ntau tsim raws cov qauv tam sim no hauv Suav. Ib qho yog nruab nrab alkali iav fiber ntau, code npe c; Ib tug yog Alkali Dawb iav Fiber, Code npe E. Lub ntsiab sib 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 tsis alkali iav fiber ntau. Kuj tseem muaj cov khoom tsis yog cov qauv ntawm cov iav khob ntawm kev ua lag luam. Feem ntau paub cov iav siab alkali iav fiber ntau. Cov ntsiab lus ntawm alkali hlau hlau oxides yog ntau dua 14%. Cov khoom siv raw rau ntau lawm yog iav lossis iav fwj. Qhov no ntawm cov iav fiber muaj cov dej tsis zoo, cov neeg kho tshuab tsis muaj zog thiab tsis muaj hluav taws xob hluav taws xob. Nws tsis raug tso cai los tsim cov khoom raws li cov kev cai hauv tebchaws.
Feem ntau tsim nyog nruab nrab alkali thiab tsis alkali iav fiber ntau xov cov xov cov xov paj Txhua cov paj yas paj tau cim nrog tus lej, tus lej ntaus thiab qib kawm, thiab daim ntawv tshuaj ntsuam xyuas cov khoom lag luam yuav tsum raug muab rau hauv lub thawv. Cov ntawv kuaj xyuas khoom lag luam suav nrog:
1. Lub npe ntawm cov chaw tsim tshuaj paus;
2. Code thiab qib ntawm cov khoom lag luam;
3. Tus naj npawb ntawm cov qauv no;
4. Stamp Lub Foob tshwj xeeb rau kev tshuaj xyuas zoo;
5. NET qhov hnyav;
6. Lub thawv ntim khoom yuav tsum muaj lub npe lub npe, cov qauv code, tus lej, tus lej cim, hnub hnyav, thiab lwm yam, thiab lwm yam.
Yuav ua li cas rov ua iav fiber khib nyiab txhab kom lo lo lus nkau thiab xov?
Tom qab tawg, nkim iav feem ntau siv tau los ua cov khoom siv raw rau cov khoom iav iav. Qhov teeb meem ntawm txawv teb chaws / ntoo ntub tus neeg sawv cev yuav tsum tau daws. Cov paj khib nyiab tuaj yeem siv los ua cov iav cov khoom lag luam fiber ntau, xws li muaj kev xav, frp, pobzeb, thiab lwm yam.
Yuav ua li cas kom tsis txhob muaj kab mob tom qab lub sij hawm ntev sib chwv nrog iav fiber ntau xov?
Kev ua haujlwm ntau lawm yuav tsum tau looj qhov ncauj qhov ntswg, hnab looj tes kom tsis txhob muaj daim tawv nqaij ncaj qha nrog cov xov paj fiber ntau.
