Cov ntsiab lus tseem ceeb rau kev soj ntsuam zoo thiab kev tswj xyuas cov ntaub fiberglass
Fiberglass ntaubtsis yooj yim li ib daim ntaub xwb. Nws qhov kev ua tau zoo sib txawv tuaj yeem ua tau ntau dua qhov sib txawv ntawm paj rwb thiab denim. Piv txwv li, txawm tias tib lub thickness ntawm "0.18mm", qhov ntev -lub sij hawm acid thiab alkali corrosion tsis kam ntawm daim ntaub woven nrog nruab nrab -alkali fiberglass yuav txawv los ntawm ob peb zaug piv rau cov ntaub woven nrog alkali -dawb fiberglass.
Ua ntej, xav txog cov iav muaj pes tsawg leeg; qhov no yog cov ntaub ntawv "genetic code." Nws feem ntau muab faib ua alkali-dawb (E- iav) thiab nruab nrab-alkali (C- iav). Alkali-dawb ntaub muaj rwb thaiv tsev zoo heev thiab muaj zog tiv thaiv huab cua, ua rau nws xaiv thawj zaug rau rwb thaiv tsev lub cev muaj zog thiab siab - cov ntaub ntawv sib xyaw. Nruab nrab-alkali ntaub yog pheej yig dua thiab muaj cov kua qaub zoo dua, tab sis nws yog rhiab rau qhov chaw ntub dej. Txawm hais tias nws tau siv rau kev rwb thaiv tsev hauv cov nroj tsuag tshuaj los yog hauv cov hluav taws xob hauv hluav taws xob, nws txoj cai caj ces txiav txim siab nws txoj hmoo. Qhov kev npau taws tshaj plaws uas kuv tau pom yog siv cov khoom nruab nrab -alkali ntaub ntawm cov khoom siv sab nraum zoov hauv qhov chaw ntub dej hiav txwv; nws tig mus rau hmoov hauv tsawg dua rau lub hlis.
Thib ob, xav txog cov weave thiab cov neeg ua haujlwm kho mob; qhov no yog cov ntaub ntawv "post-natal development." Plain weave, twill weave, thiab satin weave- sib txawv weaves ua rau cov ntaub sib txawv, kev pab, thiab lub zog. Plain weave yog qhov ntom thiab tawv tshaj, twill weave yog softer, thiab satin weave yog softest thiab muaj qhov zoo tshaj plaws. Cov neeg ua haujlwm kho mob, tseem hu ua impregnating agents, tau muab faib ua hom kev txhawb zog (kev sib raug zoo nrog cov resin) thiab hom textile (tsim rau kev sib txuas tom ntej). Puas yog koj yuav cov ntaub no los ua fiberglass? Koj yuav tsum xaiv tus neeg sawv cev txhawb nqa; txwv tsis pub, cov resin yuav tsis tuaj yeem tuav cov fibers, ua rau cov khoom lag luam zoo li cov mov tsis qab, tawg yooj yim . 90% ntawm cov neeg yuav khoom tshiab tsis pom qhov nthuav dav no.
Thib peb, tsis txhob saib ntawm ib tus lej: qhov hnyav thiab tuab. Cov neeg tsim khoom feem ntau sau lawv cov khoom raws li "grammage," xws li 300 grams ib square meter. Txawm li cas los xij, txawm tias tib yam 300 grams, cov nplooj ntawv tuab tuaj yeem xoob, thaum cov nplooj ntawv nyias nyias yuav yog qhov ntom ntom, ua rau muaj zog sib txawv. Nco ntsoov xav txog ob qho tib si "qhov hnyav ib cheeb tsam" thiab "thickness." Nws yog qhov zoo tshaj plaws los thov cov khoom siv los ntawm cov chaw tsim khoom, uas feem ntau muaj cov ncauj lus kom ntxaws kev sib piv cov lus rau cov qauv sib txawv. Cov tuam txhab muaj npe nrov, xws li Zhengde Cov Npuag Tshwj Xeeb, uas muaj kev paub dhau los ntawm cov ntaub tshwj xeeb, muab cov ntaub ntawv ntxaws ntxaws, qhia meej txog ntau yam khoom siv hluav taws xob thiab thermal- qhov no qhia txog lub luag haujlwm.
Plaub, qhia meej txog cov xwm txheej khaws cia thiab "lub neej txee." Txawm tias tsis yog khoom noj, nws tseem yuav tsum tau ceev faj cia. Fiberglass ntaub yog susceptible rau ya raws; kev ntim khoom puas lossis lub sijhawm ntev cia hauv lub tsev khaws khoom ntub yuav txo nws lub zog. Cov khoom lag luam raug cai yuav tsum muaj cov tshuaj desiccant hauv ntim, thiab cov ntim sab nrauv yuav tsum muaj dej noo- pov thawj. Tsis txhob khaws cia ntau dhau; Nws feem ntau pom zoo tias lub sijhawm khoom tsim nyog yuav tsum tsis pub tshaj 12 lub hlis.
