Hydroxyethyl Cellulose (HEC) He maha nga mahi, tae atu ki: te whakapakeke, te whakatarewa, te here, te whakaemulsifying, te hanga kiriata, te whakapumau, te whakamarara, te pupuri 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 ki 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 ka 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.
