Kev phom sij thiab cov khoom muaj kev phom sij
- Tsis-toxic thiab tsis muaj kev phom sij: nno dispersant (tshuaj lom neeg lub npe metaphthalenesulfonate) tsis raug cais raws li kev phom sij. Nws tsis muaj mob toxicity thaum siv tas li, tab sis ntev-ncua kev nqus cov plua plav lossis cov tawv nqaij ncaj qha yuav tsum zam.
- Corrosive: tus nqi pH yog 7-9 (nruab nrab kom tsis muaj zog alkaline). Nws tsis muaj kev ua kom muaj zog rau cov khoom siv hlau, tab sis kev sib cuag ntev yuav ua rau cov khoom siv oxidation me me rau cov khoom xws li tooj liab thiab txhuas. Nws raug nquahu kom khaws nws hauv corrosion-resistant ntim.
Cia thiab Kev Lag Luam Tshwj Xeeb
- Kev Cia Yuav Tsum: Nws yuav tsum khaws cia rau hauv qhov chaw txias (tsawg dua lossis sib npaug nrog qhov chaw 40, kom qhuav thiab av noo. Lub txee lub neej feem ntau yog 2 xyoos.
- Kev tiv thaiv kev ntsuas: Goggles, hnab looj tes thiab cov ntsej muag plua plav yuav tsum hnav thaum lub sijhawm ua haujlwm. Yog tias nws tau nkag mus rau hauv kev sib cuag nrog daim tawv nqaij, yaug nrog dej huv rau 15 feeb.
Cov Ntawv Thov Cov Ntawv Sau Npe
Ze Kev Lag Luam
- Cov xim zas luam dej tsis tau: nno
- Kev sib xyaw nrog MF: MF (Methylnaphat Sulfonic kua qaub fortalyd fiticdehyde condensation cov khoom) muaj qhov kub siab ntxiv (150 degree). Thaum compounded nrog NNO (130 degree), nws tuaj yeem txhim kho qhov siab-kub ua kom zoo thiab ua ib qho kev sib xyaw ua ke.
