Ukuqulunqwa kunye neempawu zefiber yeglasi
Iglasi esetyenziselwa ukuvelisa i-fiber yeglasi yahlukile kunezinye iimveliso zeglasi. Iglasi esetyenziselwa iintsinga ezithe zathengiswa kwihlabathi ibandakanya i-silica, i-alumina, i-calcium oxide, i-boron oxide, i-magnesium oxide, i-sodium oxide, njl.Funda ngokugqithisileyo -
Malunga nefibre yeglasi
Ukuhlelwa kweentsinga zeglasi Ngokwemilo kunye nobude, ifayibha yeglasi inokwahlulwa ibe yifayibha eqhubekayo, ifayibha yobude obusisigxina kunye noboya beglasi; Ngokokwakheka kweglasi, inokwahlulwa ibe yialkali yasimahla, ikwazi ukumelana neekhemikhali, ialkali ephezulu, ialkali ephakathi, amandla aphezulu, iela ephezulu...Funda ngokugqithisileyo -
Iimpawu zefiber yeglasi
Ifayibha yeglasi inokumelana nobushushu obuphezulu kunefayibha ephilayo, ukungatshi, ukumelana nomhlwa, ukugquma ubushushu obulungileyo kunye nokugqunyelelwa kwesandi (ingakumbi uboya beglasi), ukomelela okuphezulu kunye nokugquma kombane okulungileyo (okufana ne-alkali yeglasi yefayibha esimahla). Nangona kunjalo, i-brittle kwaye ihluphekile thina...Funda ngokugqithisileyo -

Lenziwa njani ilaphu lefiberglass?
Ilaphu leglasi yefiber luhlobo lwelaphu elingenanto elinokujikeleza okungajikwanga. Yenziwe ngezinto ezintle zeglasi ngothotho lokunyibilika kobushushu obuphezulu, ukuzoba, ukuluka umsonto kunye nezinye iinkqubo. Amandla amakhulu axhomekeke kwi-warp kunye ne-weft direction yelaphu. Ukuba amandla e-warp okanye weft a...Funda ngokugqithisileyo -
Unokukhetha njani umenzi welaphu le-fiberglass ekumgangatho ophezulu onganyangeki emlilweni?
1. Ukufaneleka kunye nesikali Ishishini labasebenzi bexeshana alide, kwaye ishishini lexesha elide alikhohlisi. Okokuqala, kufuneka sikhethe iibrendi ezineminyaka yokusebenza, amandla ebrand kunye nefuthe kushishino ukuqinisekisa ukunikezelwa kweemveliso kwangexesha kunye noqinisekiso lomgangatho. Ifayibha enamandla...Funda ngokugqithisileyo -
Ubomi obudlulileyo kunye nobukho bepolytetrafluoroethylene
I-Polytetrafluoroethylene (PTFE) yafunyanwa ngusokhemisti uGqr Roy J. Plunkett eDuPont's Jackson Laboratory eNew Jersey ngo-1938. Xa wayezama ukwenza irefrigerant entsha yeCFC, i-polytetrafluoroethylene ipholymerized kwisitya sogcino olunoxinzelelo oluphezulu (intsimbi ekudonga lwangaphakathi lwe inqanawa beca...Funda ngokugqithisileyo -
Itekhnoloji ye-carbon fiber yanamhlanje
Indlela yeshishini yanamhlanje ye-carbon fiber yinkqubo ye-precursor fiber carbonization. Ukwakheka kunye nomxholo wekhabhoni weentlobo ezintathu zeentsinga ezikrwada zibonisiwe kwitheyibhile. Igama lefayibha ekrwada yekhabhoni ifayibha yekhemikhali yecandelo lekhabhoni /% isivuno sefayibha yekhabhoni /% ifayibha yeviscose (C6H10O5...Funda ngokugqithisileyo
