Butyldiglycol Acetate (BDGA) Supplier

Kuyini i-Butyldiglycol Acetate?

I-Butyldiglycol acetate (BDGA), eyaziwa nangokuthi i-diethylene glycol butyl ether acetate (DGBA), iyi-acetate ester ye-butyldiglycol. Ukuxhumana kwe-ester kunciphisa kakhulu ukuncibilika kwamanzi kwayo uma kuqhathaniswa ne-BDG futhi kuphakamisa iphuzu layo le-flash point ku-~116°C, kuyifaka njengoketshezi oluvuthayo kunokuba kube oluvuthayo. I-BDGA inezinga eliphansi kakhulu lokuhwamuka kwama-ester e-glycol ether ester okuhweba (~0.01 uma kuqhathaniswa ne-n-butyl acetate = 1), okwenza kube yisithambisi esinamandla esibambezela isikhathi esivulekile ezinhlelweni zokumboza futhi sinikeze umphumela wokuncibilika ohlala isikhathi eside, okhulula kancane ezinhlelweni zokuhlanza ezikhethekile.

Izicelo Zokumboza Nokuhlanza

Ezembozweni ezithwala izinyibilikisi kanye neziqinile kakhulu, i-BDGA isetshenziswa njengesivimbeli ukuvimbela amaphutha ebusweni (ukufiphala, ukuqhekeka, ikhasi eliwolintshi) okubangelwa ukuhwamuka kwe-solvent okusheshayo kakhulu. Isebenza kahle kakhulu ekumbozweni kokulungiswa kwezimboni kanye nezimoto. Ekuhlanzeni okukhethekile, i-BDGA iyi-solvent enamandla enamandla yokususa i-resin, ingcina, uyinki, kanye nezinsalela ze-polymer emishinini yezimboni, emishinini yokunyathelisa, kanye nesitshalo sokugcoba. I-flash point yayo ephezulu (uma iqhathaniswa nama-ketone nama-ester avame ukusetshenziswa ekuhlanzeni okunjalo) yenza kube ukukhetha okuphephile ezindaweni lapho ukulandela i-flash point kubalulekile khona.

Imininingwane Yokunikezwa

I-Terracore Chemicals inikeza i-BDGA yezinga lobuchwepheshe kuma-drum. Sicebisa ngokusetshenziswa kwayo ezingxubeni ze-retarder zezinhlelo ezithile zokumboza kanye nezidingo zayo zokuphatha (ingasha esikhundleni sokuhlukaniswa okuvuthayo, kodwa isadinga umoya ofanele kanye ne-PPE).
