Qee qhov kev paub txog cov khoom siv iav kom zoo nkauj

Cov iav ntim cov txheej txheem ua tiav ntawm lub hauv paus ntawm iav yog feem ntau siv hauv cov tshuaj pleev ib ce thiab tshuaj txhua hnub, thiab tau txais kev pom zoo los ntawm cov neeg siv rau lawv cov pob tshab thiab zoo tes. Txawm li cas los xij, muaj ntau yam khoom siv iav, thiab kev xaiv ntawm cov khoom siv feem ntau yog txuas nrog cov khoom qib. Piv txwv li, nyob rau hauv lub khw cologne, cov khoom tseem ceeb ntawm cov naj hoom fwj yog siv lead ua dawb iav, thaum lub khob iav uas nrov tshaj plaws hauv kev ua lag luam yog ua los ntawm cov iav dawb. Feem ntau ntawm cov khoom siv yog ua haujlwm.

1. Khoom txhais.

Cov khoom tseem ceeb ntawm iav: Na2O·CaO·6SiO2

Cov iav yog tsim los ntawm kev sib xyaw ntawm silica thiab lwm yam tshuaj (feem ntau yog tsim los ntawm: dej qab zib tshauv, limestone, quartz). Cov qauv sib txuas tsis tu ncua yog tsim thaum lub sij hawm melting, thiab cov viscosity maj mam nce thiab hardens thaum txias. Cov tshuaj muaj pes tsawg leeg ntawm cov iav zoo tib yam yog Na2SiO3, CaSiO3, SiO2 los yog Na2O·CaO·6SiO2, thiab lwm yam. Cov khoom tseem ceeb yog silicate ob ntsev, uas yog ib qho amorphous khoom nrog random qauv.

2. Cov khoom siv.

a. Zoo heev pom-dhau thiab lub teeb kis tau tus mob.

b. Cov txheej txheem tsim khoom yog ncaj nraim.

c. Cov duab yog dawb thiab hloov tau.

d. Siab hardness.

e. Thaum tshav kub kub-resistant, huv si thiab yooj yim los ntxuav.

f. Tsawg tensile zog.

g. Yuav siv tau ntau zaus.

3. Khoom qeb.

Cov iav tau muab faib ua cov khoom siv dawb zoo tib yam, cov khoom siv dawb siab, cov khoom siv ultra-dawb thiab siv lead ua dawb. Cov xim sib txawv tuaj yeem cuam tshuam ncaj qha rau pob tshab thiab brittleness ntawm cov khoom iav. Qhov zoo ntawm cov khoom siv raw, qhov zoo ntawm cov iav khoom tsim. Nqe kuj txawv. Cov khoom siv dawb ntau tshaj plaws iav lub raj mis siv cov ntaub ntawv siv dua tshiab (feem ntau hu ua iav tawg) hauv cov khoom xyaw ntau lawm, thiab tus nqi ntawm cov khoom siv dawb thiab siv lead ua dawb yog ntau dua li cov khoom siv dawb. High-dawb iav yuav tsum xaiv cov khoom zoo thiab quartz xuab zeb nrog tsawg impurities thiab siab ceev, thiab siv lead ua dawb cov ntaub ntawv yog ua tiav nrog quartz pob zeb ua cov khoom tseem ceeb thiab silica li cov khoom pab.

4. Cov txheej txheem tsim khoom.

Ntxiv nrog rau cov khoom siv raw xws li quartz xuab zeb, dej qab zib tshauv, feldspar thiab limestone, molding ntawm iav khoom kuj yuav tsum tau ntxiv cov khoom siv xws li clarifying agents, fluxing agents, opacifiers, colorants, decolorizing agents, oxidizing agents and reduce agents. Tom qab melting thiab homogenization, nws yog tiav thiab zoo li tus, thiab ces annealed.

5. Txoj kev ua haujlwm.

Cov txheej txheem tseem ceeb ntawm iav yog ntau yam, nrog rau kev siv tshuab tshuab, tshuab tshuab, extrusion molding, kev kos duab, thiab lwm yam. Ntawm lawv, cov iav dawb yog tsim los ntawm cov tshuab kab hauv Suav teb, thaum siv lead ua dawb iav yog tsim los ntawm cov tshuab imitation. .

6. Siv cov khoom ntim cov iav kom zoo nkauj.

Cov iav ntim rau cov tshuaj pleev ib ce feem ntau yog cov khoom siv dawb siab, thiab cov khoom siv high-end kuj siv cov khoom siv lead ua dawb, xws li cov fwj tshuaj tsw qab. Los ntawm kev ua haujlwm sib sib zog nqus, iav tuaj yeem ua rau hauv cov ntim ntim xws li cov fwj tshuaj nplaum, cov fwj tshuaj, lub raj mis toner, lub raj mis tshuaj pleev, lub hauv paus fwj, thiab cov roj tseem ceeb fwj.

7. Kev txhim kho ruaj khov.

Tom qab cov khoom siv iav tau noj los ntawm kev ua lag luam, lawv tuaj yeem rov ua dua thiab rov ua dua, thiab rov qab siv dua. Lawv yog cov khoom ntsuab thiab ib puag ncig tus phooj ywg.
