Hydroxyethyl Cellulose (HEC) He maha nga mahi, tae atu ki: te whakamaroke, te aukati, te here, te whakaemulsifying, te hanga kiriata, te whakapumau, te whakamarara, te pupuri i te wai, me te hanga colloids whakamarumaru.He tino wairewa i roto i te wai wera, matao ranei, ka taea te hanga hei otinga i roto i te whānuitanga o nga pokey, a he tino pai te aukati ki nga electrolytes memeha.
tikanga tuatahi)
Tāpiri tika i te wa e huri ana i te pigment:
1. Taapirihia he wai purea tika ki te peere nui kua oti te whakakorikori teitei (ko te tikanga, ka taapirihia te ethylene glycol, te makuku me te kaihoko hanga kiriata i tenei taahiraa).
2. Tīmatahia te kōrori i te tere iti ka ata tatari kia taurite te hydroxyethyl cellulose ki roto i te otinga.
3. Whakakorikori tonu kia ruku nga matūriki katoa.
4. Katahi ka taapirihia he maatete antifungal, he taapiri kawakore penei i nga awhina whakamarara i te poaka, te wai haukini.
5. Oho kia rewa katoa te hydroxyethyl cellulose (ka tino piki te pokey o te otinga) i mua i te taapiri i etahi atu waahanga ki roto i te tauira, ka huri ki te huri tae noa ki te peita.
Tikanga Tuarua)
Kua rite ki te waipiro whaea hei whakamahi:
Ko tenei tikanga ko te whakarite tuatahi i te waipiro whaea me te kukū teitei ake, katahi ka taapiri atu ki te peita taherapa.Ko te painga o tenei tikanga he nui ake te ngawari, ka taea te taapiri tika ki te peita kua oti, engari me tika te rokiroki.He rite nga kaupae ki nga kaupae 1-4 i roto i te tikanga (1), ko te rerekee ko te kore he hiahia mo te kutikuti kutikuti teitei, ka taea anake te whakamahi i etahi o nga kaitakawaenga e kaha ana ki te pupuri i te hydroxyethyl cellulose kia marara rite i roto i te otinga. .Me whakaoho tonu kia rewa katoa ki roto i te wairewa viscous.Me tohu ko te kaihoko antifungal me whakauru wawe ki te waipiro whaea.
Tikanga (3)
Mo te phenology rite pareti:
I te mea he ngoikore nga whakarewa pararopi mo te hydroxyethyl cellulose, ka taea te whakamahi i enei whakarewa pararopi ki te whakarite pareti.Ko nga wairewa pararopi e whakamahia nuitia ana ko nga wai pararopi penei i te ethylene glycol, propylene glycol, me nga mea hanga kiriata (hei tauira, hexanediol, Butyl CARBITOL acetate) i roto i te hanga peita.He ngoikore hoki te wai tio, no reira ka whakamahia te wai tio me nga wai pararopi hei taka pareti.
Ko te pāreti-rite hydroxyethyl cellulose ka taea te taapiri tika ki te peita.Kua tino tetere te hydroxyethyl cellulose i roto i te ahua pāreti.Ina tāpirihia ki te peita, ka memeha tonu, ka mātotoru.Whai muri i te taapiri, me whakaoho tonu kia rewa te hydroxyethyl cellulose me te rite.
Ko te tikanga, ka konatunatua te pāreti ki nga wahanga e ono o te whakarewa pararopi, te wai hukapapa ranei me tetahi wahanga o te hydroxyethyl cellulose.I muri tata ki te 5-30 meneti, ka whakamarohia te hydroxyethyl cellulose me te tino pupuhi.I te raumati, he tiketike rawa te pāmahana o te wai, kaore e pai mo te pareti.
Ko nga mea e tika ana kia aro ki te whakarite i te waipiro whaea hydroxyethyl cellulose:
Ko te Hydroxyethyl cellulose te tikanga he paura tukatuka me nga mea kirikiri.I te mea ka tuhia nga mea e whai ake nei, he ngawari ki te hapai me te memeha ki te wai.
1. I mua, i muri i te taapiri i te hydroxyethyl cellulose, me whakaoho tonu kia tino marama, kia marama te otinga.
2. Me ata tatari ki roto i te ipu whakaranu.Kaua e whakauru tika i te hydroxyethyl cellulose kua hanga hei kapia, hei poi ranei ki roto i te oko whakaranu.
3. Ko te pāmahana wai me te uara pH o te wai he tino hononga ki te whakakorenga o te hydroxyethyl cellulose, no reira me aro nui ki a ia.
4. Kaua rawa e whakaurua etahi matū kawakore ki te ranunga i mua i te whakamakuku i te paura hydroxyethyl cellulose ki te wai.Ko te whakanui ake i te pH i muri i te makuku ka awhina i te whakakorenga.
5. I te mea e taea ana, taapirihia he kaihoko antifungal i te wa e taea ai.
6. I te wa e whakamahi ana i te hydroxyethyl cellulose teitei, ko te kukū o te waipiro whaea kia kaua e teitei ake i te 2.5-3% (ma te taumaha), mena ka uaua te hapai i te waipiro whaea.
