Lisebelisoa:Ethylene glycol tertiary butyl ether, e ka sehloohong e fapaneng le ethylene glycol butyl ether, ka lehlakoreng le leng, monko o fokolang haholo, toxicity e tlaase, reactivity e tlaase ea photochemical, joalo-joalo, ho halefa ha letlalo, le ho lumellana ha metsi, botsitso ba ho hasana ha pente ea latex. boholo ba li-resin le li-solvents tsa organic, le hydrophilicity e ntle. E ka sebelisoa haholo libakeng tse ngata tse kang ho roala, enke, ho hloekisa, fiber wetting agent, plasticizer, organic synthesis intermediate le ho tlosa pente. Lisebelisoa tsa eona tsa mantlha ke tse latelang:
1. Aqueous coating solvent: haholo-holo bakeng sa litsamaiso tse nang le metsi a qhibilihang, pente ea indasteri ea pente ea latex e qhalakahang. Hobane boleng ba HLB ba ETB bo haufi le 9.0, mosebetsi oa eona tsamaisong ea ho qhalakanya o phetha karolo e le dispersant, emulsifier, rheological agent le cosolvent. E na le ts'ebetso e ntle bakeng sa pente ea latex, colloidal dispersion coating le ho qhibiliha ha resin e nang le metsi ka har'a liphahlo tse kenngoeng ke metsi. , Bakeng sa pente ea ka hare le ea ka ntle mehahong, primer ea likoloi, tinplate ea mebala le masimo a mang.
