Ko te Hydroxyethyl cellulose (HEC) he ma, he kowhai marama ranei, he hongi, he totoka kikokore, he paura ranei kua oti te whakarite ma te whakaeera o te cellulose kawakore me te ethylene oxide (te chlorohydrin ranei).Ko nga etera cellulose wairewa nonionic.Na te mea he pai nga ahuatanga o te HEC mo te matotoru, te aukati, te whakamarara, te emulsifying, te honohono, te hanga kiriata, te tiaki i te makuku me te whakarato i nga colloids whakamarumaru, kua whakamahia nuitia i roto i te torotoro hinu, te paninga, te hanga, te rongoa me te kai, te kakano, te hanga pepa me te polymers.Polymerization me etahi atu mara.Ko te Hydroxyethyl cellulose he kore iu i te pāmahana me te pehanga noa, ka karo i te haumākū, te wera me te pāmahana teitei, a he tino pai te whakarewatanga o te tote mo te dielectrics.Ko tana wairewa wai ka whakaaetia kia mau nga tote teitei me te pumau.
Tohutohu
Whakauru tika ki te hanga
1. Taapirihia he wai ma ki roto i te peere nui e mau ana ki te miihini kutikuti teitei.
2. Tīmatahia te kōrori i te tere iti, ka tatari kia ata rite te waikura hydroxyethyl cellulose ki roto i te otinga.
3. Whakakorikori tonu kia ruku nga matūriki katoa.
4. Kātahi ka tāpirihia ngā āpiha antifungal, ngā tāpiritanga kawakore pērā i te poaka, te awhina whakamarara, 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 kia oti ra ano te hua.
Ka mau ki te waipiro whaea
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 penapena pai.He rite nga kaupae ki nga kaupae 1-4 i roto i te tikanga 1, engari ko te whakakorikori teitei kaore e hiahiatia kia rewa katoa ki roto i te wairewa viscous.
Kia tupato
I te mea he paura, he totoka ranei te cellulose hydroxyethyl cellulose, he ngawari ki te hapai me te memeha i roto i te wai mena ka tuhia nga take e whai ake nei.
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 poipoi ranei ki roto i te oko whakaranu i te nui, i te tika ranei.
3. Ko te pāmahana wai me te uara pH o te wai he hononga nui ki te whakakorenga o te hydroxyethyl cellulose, no reira me aro nui ki a ia.
4. Kaua rawa e taapiri etahi matū kawakore ki te ranunga i mua i te whakamahanatanga o te paura hydroxyethyl cellulose e te wai.Ko te whakanui ake i te uara PH i muri i te whakamahana he awhina mo te whakakore.
5. I te mea e taea ana, taapirihia he kaihoko antifungal i te wa e taea ai.
6. A, no te whakamahi i te hydroxyethyl cellulose teitei-nui, ko te kukume o te waipiro whaea kia kaua e teitei ake i te 2.5-3%, ki te kore he uaua ki te whakahaere i te waipiro whaea.Ko te hydroxyethyl cellulose i muri i te maimoatanga he mea ngawari ki te hanga kapia, awheawhe ranei, a ka kore e hanga he colloids porowhita korekore i muri i te taapiri wai.
