Kei a ia nga ahuatanga matū whānui o te hākawa, ā, he māmā te whakamaroke ki te waipiro me te waikawa ahetiki i te aroaro o te houra caustic me te waikawa pararopi.
Ko te Ethylene glycol diacetate he matū matū kei a ia nga ahuatanga matū whānui o te hākawa, ā, he māmā te hauwai ki te waipiro me te waikawa acetic i te aroaro o te houra me te waikawa pararopi.
Te kaupapa me nga ahuatanga:
He tino pai tenei hua, he pai, he haumaru me te kore paitini whakarewa pararopi. Ka whakamahia nuitia i roto i te umanga rongoa; He kaihoko whakamaora ester mo te whakarewa i te kapia; Kei te whakamahia ano he whakarewa pai mo nga momo kapia pararopi, ina koa ko te nitrocellulose, me te mea hei rauemi mata mo nga whakangao hiako; Hei whakarewa mo te peita rehu nitro, te mangumangu ta, te ester cellulose, me te peita rewharewha i roto i nga paninga peita. I etahi wa ka whakamahia ano he kaihoko tiaki waikawa.
Packaging and storage：
He ngawari tenei hua ki te hydrolyze, whakarongo ki te parewai me te hiri. I te wa o te kawe me te rokiroki, me wehe nga mura ahi tuwhera, me penapena nga hua ki te waahi makariri, maroke kia kore ai te wera, te makuku, te ra me te ua.
