Ceeb toom tshuaj ntim ntim

Cov neeg siv khoom tshwj xeeb:

1. Cov tshuaj tsw qab;

2. Pob tshab iav;

3. 50ml kaus poom muaj peev xwm;

4. Rau lub fwj xwmfab, tsis muaj kev tshwj xeeb rau cov tuab tuab ntawm lub taub hau.

5. Lub twj tso kua mis yuav tsum tau nruab, thiab qhov loj me me ntawm lub taub hau taub tau pom tias yog tus qauv chaw nres nkoj Fea15;

6. Raws li rau kev ua haujlwm tom qab, luam ntawv yuav tsum ua ntej thiab tom qab;

7. Sgd txiv neej nqus mis tuaj yeem lees txais;

8. Heev nto moo tiav.

Raws li cov neeg siv khoom thov, peb pom zoo kom tus txiv neej nqus lub raj mis nrog lub qhov ncauj muaj peev xwm ntawm 55mL. Thiab qhov no yog cov tshuaj tsw qab ntim lub raj mis, peb pom zoo tswj kom muaj qhov kev pab ntawm tus neeg qhua zaum kawg, uas tsis yog thaum tus qhua tuaj.

Cov neeg siv khoom yuav tsum muaj siab heev transparency thiab nto tiav, yog li peb pom zoo cov neeg siv khoom siv cov txheej txheem hluav taws. Cov tshuaj tua hluav taws xob polishing yog feem ntau siv los ntawm cov tshuab ntim iav rau cov iav fwj nrog cov dej siab ua tiav, thiab feem ntau yog siv nyob rau hauv kev tsim cov naj hoom fwj. Cov txheej txheem hluav taws xob pleev xim yog siv cov dej txias heev (ntau dua 1,000 degrees Celsius) nplaim taws los tsim, yog li ntawd lub iav molecules ntawm lub npoo yog rearranged.

Peb siv oxygen ua cov oxidant kom ua tiav cov nplaim taws kub heev. Ntawm lawv, lub siab, lub zog nqus tshwj xeeb, thiab lub sijhawm tiv tauj ntawm cov nplaim hluav taws thiab cov iav yog nruj me ntsis tswj. Lub hom phiaj kawg ntawm hluav taws polishing yog los txhim kho cov kev hloov pauv thiab du ncaj qha pab daws qee qhov tsis xws luag, cov quav, quav, tuab seams, thiab lwm yam. Txawm li cas los xij, tus txheej txheem no yog tsim nyog rau cov khoom lag luam nrog cov zis me me, thiab lub sijhawm xa khoom ntawm cov ntim ntau dhau yuav ntev heev.
