Chaw ntim khoom

Khaws cia rau ntawm qhov chaw qhuav, cov duab ntxoo, muaj qhov cua.
 

1. Thawv: Siv cov thawv dav hlau ua los ntawm cov iav lossis cov polyethylene (HDPE) kom tiv thaiv kev sib kis thiab evaporation. Nco ntsoov tias lub thawv ntim tau sib xws nrog cov kua qaub.

 

2. Kub: Khw pyruvic acid nyob rau hauv qhov chaw txias, qhuav qhov chaw kom deb ntawm lub hnub ci ncaj qha thiab kub. Qhov tseeb, nws yuav tsum cia siab dua 25 ° C (77 ° F).

 

3. Qhov cua: ua kom cov chaw cia tau yog qhov cua kom tsis txhob muaj vapor perpectulation.

 

4. Daim ntawv lo: daim ntawv lo qhia meej nrog lub npe tshuaj, kev xav, thiab cov ntaub ntawv cuam tshuam kev phom sij.

 

5. Kev ceev faj kev nyab xeeb: Khaws pyuvic acid nyob deb ntawm cov ntaub ntawv tsis sib xws xws li muaj zog oxidizing cov neeg sawv cev thiab cov hauv paus. Yog tias yuav tsum muaj los ntawm cov cai hauv zos, khaws nws nyob rau hauv ib qho chaw tsim kev phom sij cov ntaub ntawv.

 

6. Cov cuab yeej tiv thaiv tus kheej (PPE): Thaum tuav pyruvate, siv cov pye, suav nrog hnab looj tes uas zoo, suav nrog cov hnab looj tes thiab hnab looj tes, kom txo qis kev raug.
