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) haere tonu te whakaoho kia makuku katoa nga matūriki (4) taapirihia 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: i te tuatahi rite rawa tenei tikanga ki te kukū teitei o te waipiro whaea, a ka tāpiri ki te peita taherapa, tenei tikanga he te painga o te ngāwari ake, ka taea te tāpiri tika ki te peita hua, engari me te rongoa 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 (pērā 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 ka 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 taapiri etahi matū taketake ki te ranunga i mua i te whakakiia 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 kaipatu 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 whakakaha. 6 na te nui o te whakakorikori i te makuku ka wera te makuku. 7 te waikura moroiti o Thickener.
