Qhov txawv ntawmfiberglassthiab yas tej zaum yuav nyuaj vim hais tias ob qho tib si cov ntaub ntawv yuav molded rau hauv ntau yam duab thiab cov ntaub ntawv, thiab lawv muaj peev xwm muab coated los yog pleev xim rau kom zoo ib yam. Txawm li cas los xij, muaj ntau txoj hauv kev los qhia lawv sib nrug:
Kev tshuaj xyuas qhov muag:
1. Kev ntxhib los mos: Fiberglass feem ntau muaj me ntsis ntxhib los yog fibrous kev ntxhib los mos, tshwj xeeb tshaj yog yog tias cov gel tsho tiv no (cov txheej txheem txheej uas ua rau nws ua tiav) puas lossis hnav. Yas nto zoo li du thiab sib xws.
2. Xim Consistency:Fiberglasstej zaum yuav muaj qhov txawv me ntsis ntawm cov xim, tshwj xeeb tshaj yog tias nws yog xuas tes tso, thaum cov yas feem ntau yog xim sib xws.
Lub cev muaj zog:
3. Nyhav:Fiberglassfeem ntau hnyav dua li yas. Yog tias koj khaws ob yam khoom zoo sib xws, qhov hnyav dua yuav yog fiberglass.
4. Lub zog thiab yoog raws:FiberglassNws muaj zog dua thiab hloov tau yooj yim dua li cov plastics feem ntau. Yog tias koj sim khoov lossis flex cov khoom, fiberglass yuav tiv taus ntau dua thiab tsis tshua muaj deform tsis tawg.
5. Suab: Thaum tapping,fiberglassfeem ntau yuav ua kom muaj zog ntau dua, sib sib zog nqus suab piv rau lub teeb, ntau lub suab ntawm cov yas.
Kev xeem tshuaj:
6. Flammability: Ob qho khoom siv tuaj yeem yog nplaim hluav taws, tab sisiav fiberfeem ntau yog hluav taws-resistant dua li yas. Kev ntsuas hluav taws xob me me (yuav ceev faj thiab nyab xeeb thaum ua qhov no) tuaj yeem qhia tau tias fiberglass nyuaj rau ignite thiab yuav tsis yaj zoo li yas.
7. Kev Ntsuas Ntsuas: Qee zaus, koj tuaj yeem siv me me ntawm cov kuab tshuaj xws li acetone. Ua ib qho me me, tsis pom qhov chaw nrog paj rwb swab soaked hauv acetone. Yas yuav pib mos los yog yaj me ntsis, thaumfiberglassyuav tsis cuam tshuam.
Scratch Test:
8.Scratch Resistance: Siv cov khoom ntse, maj mam txhuam qhov chaw. Yas yog yooj yim rau khawb duaiav fiber. Txawm li cas los xij, tsis txhob ua qhov no rau ntawm qhov chaw tiav vim nws yuav ua rau muaj kev puas tsuaj.
Kev Qhia Txog Tus Kheej:
9. Kev ntsuas qhov ntom ntom: Ib tus kws tshaj lij yuav siv qhov ntsuas qhov ntom ntom kom paub qhov txawv ntawm ob yam khoom.Fiberglassmuaj qhov ntom ntom dua li feem ntau cov yas.
10. UV Light Test: Hauv qab lub teeb UV,fiberglassTej zaum yuav muaj qhov sib txawv fluorescence piv rau qee hom yas.
Nco ntsoov tias cov hau kev no tsis yog kev dag ntxias, raws li cov yam ntxwv ntawm ob qho tib sifiberglassthiab yas tuaj yeem sib txawv nyob ntawm hom tshwj xeeb thiab kev tsim khoom. Txhawm rau txheeb xyuas qhov tseeb, tshwj xeeb tshaj yog hauv cov ntawv thov tseem ceeb, nws yog qhov zoo tshaj los sab laj nrog tus kws tshawb fawb cov ntaub ntawv lossis tus kws tshaj lij hauv thaj chaw.
