Ko te whakamahinga o te hydroxyethyl cellulose ki te peita taherapa e whai ake nei: 1. Taapiri tika i te wa e huri ana i te poaka: he maamaa tenei tikanga, he poto te wa e whakamahia ana.Ko nga waahanga taipitopito e whai ake nei: (1) te taapiri i te wai purea tika (ko te tikanga, ka taapirihia te ethylene glycol, te makuku me te kaihoko hanga kiriata i tenei wa)(2) timata te whakaoho i te tere tere me te taapiri i te hydroxyethyl cellulose (3) me whakaoho tonu kia makuku katoa nga matūriki (4) tāpirihia te aukati koriri;PH regulator, etc. (5) oho kia rewa katoa te hydroxyethyl cellulose (whakanui te pokey otinga) i mua i te taapiri i etahi atu waahanga o te tauira, te huri ki te peita.
2.Equipped ki te waipiro whaea tatari mo te whakamahi: Ko tenei tikanga he mea tuatahi ki te kukū teitei o te waipiro whaea, a ka tapiritia ki te peita taherapa, he pai ake tenei tikanga ki te ngawari, ka taea te taapiri tika ki nga hua peita, engari me penapena tika.He rite nga hikoi me nga tikanga ki nga hikoi (1)-(4) i te tikanga 1, engari kaore e hiahiatia he kaitakawaenga kutikuti teitei, me te kaitakawaenga he nui te kaha ki te pupuri i nga muka hydroxyethyl kia marara rite i roto i te otinga.Whakakorikoritia kia rewa katoa ki roto i te wairewa viscous.Me mahara ko: te aukati koriri me whakauru wawe ki te waipiro whaea.3. Congee with the phenology: as organic solvents for hydroxyethyl cellulose is a bad solvent, so these organic solvents to prepare congee.Ko nga whakarewa pararopi e whakamahia nuitia ana penei i te ethylene glycol, propylene glycol, me nga kaihoko hanga kiriata (pēnei i te hexanediol, diethylene glycol butyl acetate ranei), he waikore te wai tio, no reira he maha nga wa e whakamahia ana me nga wai pararopi hei whakarite pareti.Ka taea te tāpiri tika ki te peita o te pāreti-rite hydroxyethyl cellulose.Ko te Hydroxyethyl cellulose kua whakakiia katoatia ki roto i te pāreti.Ka taapirihia he lacquer, ka memeha tonu, ka matotoru.Whai muri i te taapiri, me whakakorikori tonu kia rewa katoa te hydroxyethyl cellulose me te rite.Ko te tikanga ko te pāreti me nga wahanga e ono o te whakarewa pararopi, te wai hukapapa ranei, me tetahi wahi o te ranunga hydroxyethyl cellulose, mo te 5-30 meneti i muri mai, ka hydrolyzed te hydroxyethyl cellulose me te pupuhi.Te raumati he nui rawa te makuku o te wai, e kore e pai mo te hanga pāreti.
3.E wha.Kia mahara ki te whakarite i te waipiro whaea o te hydroxyethyl cellulose i te mea ko te hydroxyethyl cellulose he matūriki paura kua tukinotia, he ngawari te whakahaere me te memeha ki te wai ma te aro ki nga mea e whai ake nei.1 i mua me muri i te taapiri i te hydroxyethyl cellulose, me whakaoho tonu te ranunga kia tino marama, kia marama te otinga.2 me tatari ki roto i te pahū ranu, kaua e nui te tini o nga kapia me nga poi o te hydroxyethyl cellulose kua taapiri tika atu ki te pahū ranu.3 Ko te wairewa o te hydroxyethyl cellulose e pa ana ki te pāmahana wai me te uara pH i roto i te wai, me aro nui ki.4 kaua e whakaurua etahi matū taketake ki te ranunga i mua i te kukū o te paura hydroxyethyl cellulose ki te wai.Ko te whakanui ake i te pH i muri i te ruku ka awhina ki te memeha.5 i te mea e taea ana, moata ki te taapiri i te kaihoko anti-koriri.6 i te wa e whakamahi ana i te hydroxyethyl cellulose pokey teitei, kaore e taea e te waipiro whaea te teitei ake i te 2.5-3% (gravimeter), mena he uaua te whakahaere i te waipiro whaea.Nga mea e pa ana ki te pokey o te peita taherapa:
1 Ko te nui ake o nga mirumiru hau i roto i te peita, ka piki ake te pokey.2 e tika ana te nui o te kaiwhakaoho mata me te wai e whakamahia ana i roto i te tauira peita.3 i roto i te kōtuitanga o te taherapa, te nui o te toenga whakakōkī me ētahi atu waikura.4 te nui o etahi atu mea whakapouri maori i roto i te tauira peita me te owehenga ki te hydroxyethyl cellulose.5 i roto i te tukanga o te peita, he tika te taapiri i te raupapa hikoi whakakatakata.6 na te nui o te whakakorikori i te makuku ka wera te makuku.7 te waikura moroiti o Thickener.
