Me pehea te whakamahi hydroxyethyl cellulose ki te peita taherapa
1. Ka whakamahia te Hydroxyethyl cellulose ki te hanga pāreti: I te mea ehara i te mea ngawari ki te memeha i roto i nga whakarewa pararopi, ka taea te whakamahi etahi whakarewa pararopi hei whakarite pareti.He ngoikore hoki te wai tio, no reira ka whakamahia tahi te wai tio me nga wai pararopi hei taka pareti.Ka taea te taapiri tika ki te peita tawhetawhe rite te parareti hydroxyethyl cellulose.Ko te Hydroxyethyl cellulose kua tino whakamakuku ki roto i te pāreti.Ina tapirihia ki te peita, ka tere te memeha, ka mahi ano hei whakakaha.Whai muri i te taapiri, me whakaoho tonu kia marara katoa te hydroxyethyl cellulose ka rewa.Ko te tikanga, ka mahia te pareti ma te whakaranu i nga wahanga e ono o te whakarewa pararopi, te wai hukapapa ranei me tetahi waahanga o te hydroxyethyl cellulose.I muri tata ki te 5-30 meneti, ka whakamarohia te hydroxyethyl cellulose ka tino pupuhi.(Kia maumahara he nui rawa te haumuku o te wai whanui i te raumati, no reira kaua e whakamahia hei whakakakahu i te pareti.)
2. Taapirihia tika te hydroxyethyl cellulose i te wa e huri ana i te poaka: He ngawari tenei tikanga, he poto te wa.Ko te tikanga taipitopito e whai ake nei:
(1) Taapirihia te nui o te wai purea ki roto i te peere nui o te whakaranu kutikuti teitei (te tikanga, ka taapirihia nga taputapu hanga kiriata me nga makuku i tenei wa)
(2) Tīmatahia te kōrori i te tere iti me te āta tāpirihia te hydroxyethyl cellulose
(3) Me whakaoho tonu kia marara noa nga matūriki katoa ka ruku
(4) Tāpirihia nga taapiri anti-koriri hei whakatika i te uara PH
(5) Oho kia rewa katoa te hydroxyethyl cellulose (ka tino piki ake te pokey o te otinga), katahi ka whakaurua etahi atu waahanga ki roto i te tauira, ka huri kia puta ra ano te peita.
3. Whakapaia te hydroxyethyl cellulose me te waipiro whaea hei whakamahi i muri mai: Ko tenei tikanga ko te whakarite i te waipiro whaea me te kukū teitei i te tuatahi, katahi ka tapiri ki te peita taherapa.Ko te painga o tenei tikanga he ngawari ake, ka taea te taapiri tika ki te peita kua oti, engari me penapena pai..He rite nga hikoi me te tikanga ki nga hikoi (1)-(4) i te tikanga 2, ko te rerekee ko te kore e hiahiatia he kutikuti kutikuti teitei, a ko etahi o nga kaitakawaenga he nui te kaha ki te pupuri i te muka hydroxyethyl kia marara i roto i te otinga ko Can .Me whakaoho tonu kia rewa katoa ki roto i te wairewa viscous.Me tohuhia me whakauru te kaihoko antifungal ki te waipiro whaea peita i te wa e taea ai.
4 Nga take e tika ana kia aro ki te whakarite i te waipiro whaea hydroxyethyl cellulose
I te mea ko te hydroxyethyl cellulose he paura tukatuka, he ngawari ki te hapai me te memeha i roto i te wai mena ka arohia nga mea 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 taika ranu, kaua hoki e taapiri tika i te nui o te hydroxyethyl cellulose kua hanga he kapia, he poi ranei ki roto i te tank whakaranu.
(3) Ko te pāmahana wai me te uara pH i roto i te wai he hononga nui ki te whakakorenga o te hydroxyethyl cellulose, no reira me aro nui.
(4) 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 whakamakuku ka awhina i te whakakorenga.
(5) I te mea e taea ana, taapirihia he kaihoko anti-fungal moata.
(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.
Nga mea e pa ana ki te pokey o te peita taherapa:
(1) Na te nui o te whakakorikori, ka wera rawa te makuku i te wa e marara ana.
(2) Ko te nui o etahi atu whakapouri taiao i roto i te hanga peita me te tauwehenga o te nui ki te hydroxyethyl cellulose.
(3) Mehemea e tika ana te nui o te surfactant me te nui o te wai i whakamahia i roto i te tauira peita.
(4) A, no te synthesizing taherapa, te nui o te ihirangi waikura pērā i te toenga whakakōkī.
(5) Te waikura o te whakapouri e nga microorganisms.
(6) I roto i te tukanga hanga peita, mehemea he tika te raupapa o te taahiraa o te taapiri i te whakamaarata.
7 Ka nui ake nga mirumiru hau e noho ana ki te peita, ka nui ake te pokey
