Ko te Hydroxyethyl cellulose (HEC) he ma, he kowhai marama ranei, he hongi, he kikokore, he paura totoka ranei.He mea hanga mai i te miro miro mata, te penupenu parakore ranei i ruia ki te 30% wai houra.I muri i te hawhe haora, ka tangohia ki waho ka pehia.Kotēhia kia tae rā anō te ōwehenga o te wai kawakore ki te 1:2.8, kātahi ka kuru.Kua whakaritea e te tauhohenga whakaetere, no roto i nga etera cellulose wairewa-kore.Ko te Hydroxyethyl cellulose he mea whakakaha i roto i te peita taherapa.Me aro tatou ki te whakamahi i te HEC hydroxyethyl cellulose ki te peita taherapa me nga tikanga tiaki.
1. Kua rite ki te waipiro whaea hei whakamahi: tuatahi whakamahia te hydroxyethyl cellulose HEC ki te whakarite i te waipiro whaea me te kukū teitei ake, katahi ka taapiri atu ki te hua.Ko te painga o tenei tikanga he nui ake te ngawari, ka taea te taapiri tika ki te hua kua oti, engari me penapena tika.Ko nga hikoinga o tenei tikanga he rite ki te nuinga o nga hikoinga o te tikanga 2;ko te rerekee karekau he hiahia mo te kutikuti kutikuti teitei, a ko etahi o nga kaikohikohiko he nui te kaha ki te pupuri i te hydroxyethyl cellulose kia marara rite i roto i te otinga ka taea te haere tonu me te kore e mutu Ohooho kia rewa rawa ki roto i te wairewa viscous.Heoi, me tohu ko te fungicide me whakauru wawe ki te waipiro whaea.
2. Tāpiri tika i te wa o te whakaputanga: ko tenei tikanga te mea ngawari me te wa poto rawa atu.Taapirihia he wai ma ki roto i te peere nui e mau ana ki te whakaranu kutikuti teitei.Tīmatahia ki te kōrori i te tere iti, ka tatari kia ata rite te hydroxyethyl cellulose ki roto i te otinga.Me whakaoho tonu kia ruku nga matūriki katoa.Katahi ka taapirihia nga rongoa me nga momo taapiri.Pērā i te poaka, te awhina whakamarara, te wai haukini, me etahi atu. Oho kia rewa katoa te hydroxyethyl cellulose HEC (ka tino piki te pokey o te otinga) katahi ka taapirihia etahi atu waahanga ki te tauira mo te tauhohenga.
I te mea ko te HEC he paura, he kiko totoka ranei te HEC kua tukinotia ki te mata, i te wa e whakareri ana i te waipiro whaea hydroxyethyl cellulose, kia whai whakaaro ki nga mea e whai ake nei:
(1) I te wa e whakamahi ana i te HEC hydroxyethyl cellulose teitei, ko te kukū o te waipiro whaea kia kaua e teitei ake i te 2.5-3% (ma te taumaha), ki te kore ka uaua ki te hapai i te waipiro whaea.
(2) I mua, i muri i te taapiri i te hydroxyethyl cellulose HEC, me whakaoho tonu kia tino marama, kia marama te otinga.
(3) I nga mea e taea ana, taapirihia he kaihoko antifungal i mua.
(4) 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.
(5) Kaua e taapiri 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 ruku ka awhina i te memeha.
(6) Me ata tatari ki roto i te taika ranu, kaua e taapiri i nga rahinga nui, me te taapiri tika ranei i te hydroxyethyl cellulose i hanga kapia me nga poi ki roto i te tank whakaranu.
Nga mea nui e pa ana ki te pokey o te peita taherapa:
(1) Te waikura o te whakapouri na te microorganisms.
(2) I roto i te tukanga hanga peita, ahakoa he tika te raupapa o te hikoi o te taapiri i te whakamaarata.
(3) Mehemea e tika ana te nui o te kaiwhakaoho mata me te wai e whakamahia ana i roto i te tauira peita.
(4) Ko te ōwehenga o te nui o etahi atu whakapouri taiao ki te nui o te hydroxyethyl cellulose i roto i te hanga peita.
(5) Ka hangahia te taherapa, ko te ihirangi o te toenga whakakorikori me etahi atu waikura.
(6) He tiketike rawa te pāmahana i te wa e marara ana na te nui o te whakaohooho.
(7) Ka nui ake nga mirumiru hau e noho ana ki te peita, ka nui ake te pokey.
Ko te pokey o te hydroxyethyl cellulose HEC ka huri paku i roto i te awhe pH o 2-12, engari ka heke te pokey ki tua atu i tenei awhe.Kei a ia nga ahuatanga o te matotoru, te whakatarewa, te here, te whakaemulsifying, te marara, te pupuri i te makuku me te tiaki i te colloid.Ka taea te whakarite otinga i roto i nga awhe pokey rereke.Karekau i raro i te pāmahana me te pehanga noa, karohia te haumākū, te wera me te pāmahana teitei, he tino pai te tote wairewa ki te dielectrics, me te wairewa wai ka whakaaetia kia mau nga tote teitei me te pumau tonu.
