Cov dej siv rau kho lub rooj thiab cov dej siv rau kho lub tsev muaj qhov kev mob zoo rau hauv qhov sib txuas, thiab tsis muaj kev tsoo los ntawm qhov tsoo thaum tsis mob.
• - Qhov kev daws tshuaj thiab kev ua kom zoo: Nws tuaj yeem daws tshuaj tau raws li cov ions ntawm cov loog tshuaj, cov loog tshuaj organic, thiab cov molecules ntawm cov lus qhia, siv rau hauv kev kho cov dej tsis zoo, kev kho cov aj tswv, thiab lwm yam, muaj kev kho zoo heev.
• - Qhov stability ntawm kev sib txuas rau qhov ceev: Tsis mob rau qhov ceev 300℃, txis thiab alkali, txis rau kev nyuaj, tso cai rau qhov performance zoo thaum muaj qhov xwm txheej tsis zoo, thiab txhawj rau kev nyuaj ntawm cov khoom.
• - Xaiv, tsis muaj tshuaj, thiab zoo: Muaj cov khoob tshuaj ntawm cov khoob tshuaj ntawm lub vaj, tsis muaj cov loog tshuaj tsis zoo thiab cov loog tshuaj uas tuaj yeem tshuab, siv rau hauv qhov sib txuas thiab qhov kev nyab xaiv.
• - Tswv yim ntawm kev siv khoom ntau dua: Muaj ntau lub tshuab thiab cov khoom siv tau los ntawm qhov chaw, siv tau dua, muaj kev siv hluav tais tes pheej yig, nyob rau hauv kev pib ua kom zoo dua thiab kev saib xyuam rau lub ntiaj teb.

3. Qhov kev siv tshiab ntawm ntau qhov kev ua haujlwm

Tsim khoom tseem ceeb

• - Kev kho tshuab: Pab txhawj xyuam qhov ntxiv thiab qhov tsoo ntawm cov dej tshuab, txog qhov tsis zoo ntawm kev kho tshuab, thiab ua rau muaj kev kho tshuab zoo rau cov khoom tseem ceeb xws li lub xeem thiab lub xeem ntawm qhov chaw.
• - Qhov kev siv khoom tshiab: Siv rau kev pab cov khoom tshuab thiab cov khoom tshuab, pab txhawj xyuam qhov ntxiv, qhov tsoo ntawm dej thiab qhov tsoo ntawm kev tshuab, thiab txog qhov ntau ntawm kev ua haujlwm.

Kev saib xyuam rau lub ntiaj teb thiab qhov kev siv tshuab ntawm lub ntiaj teb

• - Kev kho lub vaj: Pab txhawj xyuam qhov ntxiv ntawm lub vaj, tshuab cov ntaub ntawv tshuab thiab cov ntaub ntawv tshuab ntawm lub vaj, thiab pab txhawj xyuam qhov ntxiv thiab qhov safety ntawm lub vaj.
