iav yog ib yam ntawm amorphous inorganic non-metallic khoom uas ua los ntawm ntau yam inorganic minerals (xws li quartz xuab zeb) thiab ib tug me me ntawm cov khoom siv raw, cov khoom tseem ceeb yog silicon dioxide.Iav permeability zoo heev, tsis muaj kuab paug, muaj zog zam, nplua nuj qauv siv dav, tus nqi qis.
Pwm molding loj yog qhov tseeb, tuaj yeem tsim cov khoom siv lub teeb thiab nyias, thiab xim yog nplua nuj thiab cov txheej txheem hloov tau zoo heev. Vim nws yog ib tug sib tov, amorphous, tsis muaj ib tug ruaj khov melting thiab boiling point.Cov iav los ntawm cov khoom mus rau cov kua yog ib thaj tsam ntawm qhov kub thiab txias (piv txwv li, softening kub ntau), los ntawm lub xeev molten mus rau lub xeev ntawm cov txheej txheem kuj gradual, nruam.Raws li qhov ntsuas kub qis dua, qhov viscosity ntawm cov iav yaj tau maj mam nce, thiab thaum kawg cov iav yog tsim.Yog li ntawd, cov cuab yeej tshwj xeeb ntawm iav no tsim ib qho kev mob zoo rau kev tsim cov iav crafts.Yog li yog vim li cas cov khoom qab zib hub iav nyiam los ntawm cov menyuam yaus heev?
Ntawm tag nrho cov ntaub ntawv, iav rhawv yog qhov zoo tshaj plaws.Lub khob iav tsis muaj cov tshuaj organic hauv cov txheej txheem ntawm kev tua.Thaum tib neeg siv lub khob iav los tso khoom qab zib, lawv tsis tas yuav txhawj xeeb txog cov tshuaj lom neeg yuav raug noj rau hauv plab.Tsis tas li ntawd, cov iav saum npoo yog du thiab yooj yim los ntxuav, thiab cov kab mob thiab cov av tsis yooj yim rau hauv lub khob phab ntsa.
【 Txhais】
Lub thawv iav yog ib hom pob tshab ntim ua los ntawm cov khoom siv iav molten los ntawm tshuab thiab molding.Cov thawv ntim iav feem ntau yog siv los ntim cov kua, cov khoom siv tshuaj thiab cov khoom ua kua dej.
【 Ntsuab】
Piv nrog cov yas thiab hlau ntim, iav muaj cov pa roj carbon dioxide qis tshaj plaws nyob rau hauv tag nrho lub neej voj voog los ntawm kev tsuas, kev thauj mus los, kev tsim khoom thiab kev tsim cov khoom siv raw, kev thauj mus los ntawm cov khoom tiav, kev siv thiab rov ua dua tshiab, thiab cov pa roj carbon dioxide qis tshaj.
【 Kev ruaj ntseg】
iav tau lees paub tias yog cov khoom ntim khoom zoo tshaj plaws hauv ntiaj teb.Nws tsis muaj bisphenol A lossis plasticizer.Nrog txhim khu kev qha tshuaj lom neeg ruaj khov thiab thaiv, tsis muaj kuab paug rau cov khaub ncaws, yog li kev xaiv cov khoom siv iav yog xaiv kev noj qab haus huv, xaiv kev nyab xeeb.
[Circularity]
Cov iav muaj qhov tseem ceeb tsis kawg, iav nws tus kheej tuaj yeem rov siv dua thiab rov siv dua yam tsis muaj nqi poob, thiab lub voj voog tsis muaj qhov kawg.Txoj cai ntawm qhov teeb meem yog qhov tseem ceeb tshaj plaws hauv iav.
【 Humanist xwm】
Qhov tshwj xeeb niaj hnub muaj nuj nqi thiab kos duab ntxim nyiam ntawm kev siv iav niaj hnub tuaj yeem pom qhov zoo tshaj plaws ntawm kev pabcuam rau tib neeg.
