Dab tsi yog fiberglass, thiab nws cov qauv tsim khoom yog dab tsi?

Hauv luv luv:fiberglassyog tsim los ntawm melting iav thiab kos rau hauv fibers ib feem ntawm lub thickness ntawm tib neeg cov plaub hau. Nws sib txuas cov hardness thiab corrosion kuj ntawm iav nrog qhov yooj thiab weavability ntawm ntuj fibers, ua rau nws siv thiab nqi ntau tshaj -cov khoom siv fiber ntau niaj hnub no.

 

Tej zaum koj yuav tsis tau pom nws ncaj qha, tab sis koj yuav luag tau siv nws - nws tau pom nyob rau hauv koj lub xov tooj, koj lub dab da dej, cua turbine hniav, thiab txawm tias txheej rwb thaiv tsev hauv koj phab ntsa.

 

I. Dab tsi yog fiberglass?

 

Cov tshuaj muaj txiaj ntsig ntawm fiberglass tsis yog qhov txawv ntawm cov iav fwj thiab qhov rais uas peb siv txhua hnub. Nws cov khoom tseem ceeb yog silicon dioxide (SiO₂), ua ke nrog cov oxides xws li txhuas oxide, calcium oxide, thiab boron oxide. Qhov txawv nyob rau hauv nws daim ntawv: zoo tib yam iav yog blocky thiab nkig; thaum fiberglass, thaum kos rau hauv cov fibers zoo heev nrog ib txoj kab uas hla ntawm tsuas yog 3-24 micrometers, dhau qhov kev hloov pauv zoo- nws dhau los ua khoov tau, weaveable, thiab tuaj yeem sib xyaw nrog cov resin, thaum tseem khaws qhov zoo ntawm iav xws li kub-kub kuj, corrosion kuj, thiab hluav taws xob rwb thaiv tsev.

 

Ib qho fiberglass monofilament yog kwv yees li 1/20 txog 1/5 ntawm txoj kab uas hla ntawm tib neeg cov plaub hau. Bundling thiab weaving cov monofilaments yields ntau hom fiberglass khoom, xws li fiberglass ntaub thiab fiberglass lev.

 

II. Nws ua li cas?

 

Txoj kev tsim khoom tseem ceeb yog lub tank rauv txheej txheem kos duab, uas feem ntau ua raws li hauv qab no:

 

. Melting: Ntuj ntxhia raw cov ntaub ntawv xws li quartz xuab zeb, limestone, thiab borosilicate yog ntxiv rau lub tank rauv raws li ib tug piv txwv thiab melted rau hauv molten iav ntawm ib tug kub ntawm kwv yees li 1400 degree.

 

. Kev kos duab: Lub iav molten ntws los ntawm platinum alloy baffle phaj nyob rau hauv qab (nrog rau ntau pua mus rau phav phav perforations), ntws tawm hauv qab lub ntiajteb txawj nqus thiab raug stretched thiab txias los ntawm lub siab - tshuab nqus tsev ceev, instantly solidifying rau hauv cov fibers tsis tu ncua.

 

. Impregnation: Cov fibers rub tau tam sim ntawd coated nrog tus neeg sawv cev impregnating, uas tiv thaiv cov fibers, nce softness, thiab txhim kho compatibility nrog resins.

 

. Post-kev ua: Nyob ntawm daim ntawv thov, nws tau ua tiav rau hauv cov khoom xws li untwisted rovings, tws strands, fiberglass daim ntaub, thiab fiberglass lev.

 

Qhov ci ntsa iab ntawm cov txheej txheem no yog nyob rau hauv qhov tseeb tias iav, cov khoom siv uas "so ntawm qhov kov me ntsis," ua rau muaj kev txo qis hauv qhov tsis xws luag tom qab hloov mus rau micron - fibers loj. Yog li ntawd, nws lub zog tensile nyob deb dhau ntawm cov iav thaiv - lub zog tensile ntawm ib leeg fiberglass filament tuaj yeem ncav cuag 2000-4000 MPa, 2-3 npaug ntawm cov hlau zoo tib yam.

 

III. Vim li cas fiberglass thiaj li nrov?

 

Nws cov txiaj ntsig tseem ceeb tuaj yeem suav nrog rau 6 lo lus: lub teeb yuag, muaj zog, ruaj khov, thiab pheej yig.

 

Lub teeb yuag: Fiberglass muaj qhov ntom ntawm kwv yees li 2.5-2.6 g / cm³, sib dua li txhuas (2.7) thiab tsawg dua ib feem peb ntawm cov hlau (7.8).

Muaj zog: Nws lub zog tensile deb tshaj li cov hlau. Thaum ua ke nrog cov resin (piv txwv li, "fiberglass / FRP"), nws lub zog tshwj xeeb (lub zog / qhov sib piv) tag nrho dhau ntawm cov khoom siv hlau.

 

Durable: Corrosion-resistant, siab- kub resistant (kev khiav hauj lwm kub txog 250-}280 degree), thiab huab cua-resistant, nws tsis xeb los yog rot.

Nqe: Piv rau carbon fiber (kwv yees li 100-200 RMB/kg), fiberglass nqi tsuas yog 6-15 RMB/kg, muab cov nqi-zoo heev.

Tsis tas li ntawd, nws muaj cov rwb thaiv tsev zoo heev, thermal rwb thaiv tsev, tsis tshua muaj dej nqus, thiab tsim tau (kev ua tau zoo tuaj yeem tswj tau los ntawm kev hloov kho fiber ntau thiab layup txoj kev).

 

IV. Fiberglass siv qhov twg?

 

Nws cov kev siv yog dav heev. Nov yog qee qhov feem ntau:

 

3C Khoom Casings: Qee lub laptop thiab ntsiav tshuaj casings siv fiberglass - cov ntaub ntawv sib xyaw ua ke, uas muaj zog dua li cov yas ntshiab thiab sib dua li hlau.

 

Kev tsim kho: Fiberglass reinforced cement (GRC), cov khoom siv hauv paus rau cov dej tsis zoo, thiab cov txheej thaiv phab ntsa (fiberglass wool).

 

Kev thauj mus los: Fiberglass yog dav siv hauv tsheb bumpers, tsheb fairings, thiab nkoj hulls.

 

Cov Kev Ua Si: Nkag mus-qib nuv ntses, caij skis, thiab ntaus pob tesniv feem ntau siv fiberglass ua lawv cov khoom siv.

 

Cov ntsiab lus

 

Lub ntsiab lus ntawm fiberglass yog qhov "fiber{0}}kos duab" txheej txheem hloov iav los ntawm cov khoom "pob tshab" rau hauv "cov ntaub ntawv hloov tau yooj yim."
