Ko te huaora ether te taapiri e whakamahia nuitia ana i roto i te kumete paura maroke.Ko te Hydroxypropyl methyl cellulose ether he mahi nui ki te moata paura maroke.I muri i te rewa o te cellulose ether i roto i te kumete ki te wai, ka whakamanahia te kapia na te mahi o te mata.Ko te rauemi coagulant he pai te tohatoha i roto i te punaha, me te hydroxypropyl methylcellulose ether, hei colloid whakamarumaru, "ka takai" nga matūriki totoka me te hanga i tetahi paparanga o te kiriata whakahinuhinu i runga i tona mata o waho, kia pai ake ai te punaha moata me te whakapai ake hoki i te te rere o te kumete i te wa o te ranu me te maeneene o te hanga.
Na tona ake hanganga rapoi, ko te otinga cellulose ether e kore e ngawari ki te ngaro te wai i roto i te kumete, a ka tuku haere mo te wa roa, ka whakawhiwhia te moata ki te pupuri wai pai me te kaha mahi.Te pupuri wai o te hydroxypropyl methyl cellulose ether: Ko te tohu tino nui me te tohu taketake.Ko te pupuri wai e tohu ana ki te nui o te wai ka mau i te kumete hou i konatunatua i muri i te mahi a te kapi i runga i te turanga mimiti.Ko nga tikanga whakamatautau e whai ake nei mo te pupuri wai o te cellulose ether kua whakarāpopotohia hei matapaki.
Tikanga korehau
I te wa o te whakamatautau, whakakiia te kohanga o te Buchner ki te kumete kua konatunatua ki te wai, tuu ki runga i te pounamu tātari momi, ka tiimata te papu korehau, ka mahia te tātari momi mo te 20 meneti i raro i te pehanga kino o (400±5) mm Hg.Na, kia rite ki te nui o te wai i roto i te slurry i mua i muri i muri i te momi filtration, tātaihia te auau pupuri wai e whai ake nei.
tikanga pepa tātari
Ko te pupuri i te wai o te cellulose ether ka whakatauhia e te whakauru wai o te pepa tātari.He mea hanga mai i te mowhiti whakarewa whakarewa me te teitei, te pepa tātari me te pereti tautoko karaihe.E 6 nga papa o te pepa tātari i raro i te pokepokea ai te whakamatautau, ko te paparanga tuatahi he pepa tātari tere, ko etahi atu e 5 he pepa tātari puhoi.Whakamahia he pauna tika ki te pauna tuatahi i te taumaha o te pallet me nga paparanga e 5 o te pepa tātari puhoi, ringihia te kumete ki roto i te pokepokea whakamatautau i muri i te ranu ka waruhia, ka waiho mo te 15 meneti: katahi ka paunatia te taumaha o te pallet me nga paparanga 5 o te taumaha pepa tātari puhoi.
