Dab tsi yog qhov ntsuas qhov zoo ntawm cov ntaub fiberglass?

I. Tshawb xyuas Raw Fiber Skeleton (Fundamental Core)

Lub hauv paus zoo ntawmfiberglassdaim ntaub nyob ntawm raw fiber, nws cov pob txha.

 

Qhov taw qhia tseem ceeb: Alkali Cov ntsiab lus (Sodium Oxide / Potassium Oxide Ratio)

 

Kev faib tawm: Alkali-dawb (tsawg dua lossis sib npaug li 0.8%), Nruab Nrab Alkali (11.6%-12.4%), Siab Alkali (＞ 12%) (National Standard GB/T 18370 rau Sib Tsoo Wheel Mesh Cloth). Rau kev tiv thaiv corrosion, rwb thaiv tsev, thiab ua haujlwm hnyav, yuav tsum nruj dua alkali cov qauv.

 

Kev Tshawb Fawb Txog Kev Muag Khoom: Tsis txhob cia siab rau cov ntsiab lus tsis meej xws li "alkali-dawb / nruab nrab-alkali / siab{2}}alkali." Paub meej tias lub hauv paus ntawm iav raw cov ntaub ntawv thiab cov ntsiab lus alkali qhia. Yog tias tsim nyog, tshawb xyuas cov ntawv tshaj tawm ntawm cov khoom siv raw los xyuas kom meej tias cov ntsiab lus alkali ruaj khov thiab tsis txhob cuam tshuam rau kev ua haujlwm tag nrho.

 

Simple Corrosion Resistance Test: Muab ib qho piv txwv rau hauv 5% dilute hydrochloric acid rau 24 vib nas this. Sij hawm (hnav hnab looj tes tiv thaiv), ntxuav thiab qhuav, ces ncab thiab twist. Qhov tsawg zog poob thiab qhov zoo ntawm cov duab tuav, qhov zoo dua corrosion kuj.

 

Lub hauv paus ntsiab lus tseem ceeb: Cov khoom siv raw cov xov paj thiab alkali ruaj khov ncaj qha txiav txim siab ntev - lub neej ntev thiab lub zog ntawm cov ntaub fiberglass.

 

II. Tshawb xyuas cov txheej txheem weaving (cov qauv kev ruaj ntseg)

 

Kev soj ntsuam hauv paus

Kev soj ntsuam lub teeb pom kev zoo: High- cov ntaub zoo muaj cov xov paj sib npaug, sib kis lub teeb, thiab tsis muaj huab cua, cov xov paj tawg, cov pob qij txha, lossis cov pob, qhia txog kev sib tsoo ntawm kev sib tsoo thiab sib npaug ntawm tag nrho lub zog.

 

Mainstream Weaving Methods

 

Plain Weave: ntom thiab tawv, khawb-resistant thiab hnav-resistant, haum rau cov cua sov rwb thaiv tsev sab nrauv cladding, sab nrauv phab ntsa tawg, thiab lwm yam kev tiv thaiv.

 

Twill Weave: Sib npaug zog thiab yoog raws.

 

Satin Weave: du nto, zoo resin impregnation, haum rau fiberglass thiab FRP cov khoom (yachts, txias yees, thiab lwm yam), txo cov sab hauv thiab txhim kho tag nrho lub zog.

 

Kev sim yooj yim: Maj mam muab kua muag raws li 45℃kaum; nws yuav tsum tsis txhob rhuav yooj yim, thiab yuav tsum tsis muaj frayed npoo los yog xoob threads. Cov xov paj cohesion tau txais; yog tias nws kua muag tau yooj yim, kev sib koom ua ke tsis txaus thiab nws yuav yooj yim puas tom qab.

 

Lub hauv paus ntsiab lus tseem ceeb: Xaiv cov txheej txheem weaving raws li qhov xav tau, ua kom pom kev zoo ib yam thiab muaj kev sib koom ua ke txaus.

 

III. Tshawb xyuas qhov sizing tus neeg sawv cev txheej (qhov tseem ceeb ntawm tus nqi zais)

 

Tus neeg sawv cev sizing (surface chemical coating) yog lub ntsiab lus tseem ceeb ntawm cov kws tshaj lij, txiav txim siab txog kev sib koom ua ke ntawm cov iav fiber ntau thiab cov khoom siv matrix.

 

Hom sib txawv:

Txhim kho cov neeg ua haujlwm sizing (silane coupling agents, thiab lwm yam): tuaj yeem sib txuas nrog cov resin, ua tiav cov ntawv cog lus ruaj khov thiab txhim kho tag nrho lub zog ntawm cov khoom sib xyaw.

Tsis yog-txheej txheem / txheej txheej ib ntus (cov hmoov txhuv nplej siab, paraffin): tsuas yog yooj yim rau kev xaws, yuav tsum tau ntxuav tom qab, tsis haum rau kev txhim kho ncaj qha.

 

Yooj yim rau tus kheej- txoj kev tshuaj xyuas:

Kev ntsuas dej ntws: Hauv siab - cov ntaub ntawv zoo chemically coated, cov tee dej tsim cov hlaws thiab tsis yooj yim nkag mus; Kev nkag mus nrawm feem ntau qhia tias cov txheej txheem qis dua / ib ntus.

 

Resin impregnation test: Tso cov ntaub, ncuav resin, thiab smooth nws tawm. Uniform nkag mus nrawm thiab tsis muaj cov pob dawb qhuav qhia tias tus neeg sawv cev zoo sib xws.

 

Lub hauv paus ntsiab lus tseem ceeb: Rau cov qauv / Rau cov khoom siv fiberglass, ib qho kev txhawb nqa impregnating tus neeg sawv cev sib haum nrog cov txheej txheem resin yuav tsum raug xaiv.

IV. Tsis txhob hnov ​​​​qab txog qhov hnyav ib square meter thiab txheeb xyuas qhov ntom ntom.

 

Cov pitfalls ntau: tsom tsuas yog qhov hnyav ib square meter; Qee cov khoom cia siab rau cov qauv xoob thiab qhov khoob kom nce qhov hnyav, ua rau cov khoom tsis tshua muaj siab thiab tsis muaj zog tiag tiag.

 

Cov ntsiab lus tseem ceeb: Txheeb xyuas qhov hnyav, thickness, thiab warp thiab weft yarn ntom ib txhij.

 

Tshawb xyuas cov xov tooj ntawm warp thiab weft yarns ib chav tsev ntev kom paub meej tias cov xov xov nruj.

 

Tes hnov ​​tensile xeem: High-cov ntaub zoo muaj qhov tsawg kawg nkaus tensile deformation, tseem ceeb skeletal resistance, thiab nruab nrab lub teeb kis tau tus mob.

Kev sib piv lub hauv paus ntsiab lus: Nyob rau tib qhov hnyav, cov ntaub nyias nyias nrog qhov ntom ntom dua ... Qhov hnyav dua feem ntau qhia txog kev ua haujlwm zoo dua.

Lub hauv paus ntsiab lus: Kev ua tau zoo tsis tuaj yeem txiav txim siab los ntawm qhov hnyav xwb; kev ceev ceev thiab lub cev pob txha muaj zog yog qhov tseem ceeb.

 

Cov ntsiab lus

 

Thaum yuav daim ntaub fiberglass, tsis txhob saib tus nqi thiab qhov hnyav:

Tshawb xyuas cov khoom siv raw thiab alkali stability kom tswj tau qhov zoo ntawm cov pob txha yooj yim.

Txheeb xyuas qhov sib xws ntawm kev sib tsoo thiab txoj kev weaving qhov tsim nyog rau daim ntawv thov kom muaj kev ruaj ntseg tag nrho.

Txheeb xyuas qhov zoo ntawm tus neeg sawv cev sizing txheej kom ntseeg tau tias muaj kev sib raug zoo nrog cov khoom siv matrix.

Ua tib zoo txheeb xyuas qhov ntom ntom kom tsis txhob muaj cov khoom lag luam tsis zoo nrog cov tuab tuab thiab qhov hnyav.

Yog tias tsim nyog, ua cov kua qaub thiab alkali tsis kam immersion tests kom paub tseeb tias ntev -lub sij hawm stability.
