Ko te Hydroxypropyl methylcellulose e whakamahia nuitia ana i roto i te ahumahi hanga.I tenei ra, ka whakauruhia e ahau te tikanga whakakore o te hydroxypropyl methylcellulose me pehea te whakatau i te kounga o te hydroxypropyl methylcellulose.
Ko te tikanga mo te whakakore i te hydroxypropyl methylcellulose:
Ka taea te taapiri i nga tauira katoa ki te rauemi ma te whakaranu maroke;
A, no te hiahia ki te tāpiri tika ki te wairewa wai pāmahana noa, he pai ki te whakamahi i te momo whakamararatanga wai matao, a ka taea te matotoru i roto i te 10-90 meneti i muri i te tāpiri;
I muri i te whakaoho me te marara ki te wai wera mo te momo noa, taapirihia te wai matao me te whakaoho kia memeha;
Mena he agglomeration me te paninga i te wa e memeha ana, na te iti o te whakakorikori, te taapiri tika ranei o te wai matao ki nga tuhinga noa.I tenei wa, me tere te whakaoho;
Mena ka puta nga mirumiru i te wa o te whakakorenga, ka taea te waiho kia tu mo te 2-12 haora (kua whakatauhia kia rite ki te rite o te otinga) ka tangohia ranei ma te wehe, te pehanga, me etahi atu, ka taea hoki te taapiri i te nui o te defoamer.
Me pehea te whakatau i te kounga o te hydroxypropyl methylcellulose ngawari me te ngawari
Te Maama: E ai ki te ma, kaore e taea te whakatau mena ka taea te whakamahi noa te HPMC, a, ki te taapirihia nga maaka ma i roto i te mahi whakaputa, ka pa ki tona kounga.Heoi, he pai te nuinga o nga hua ma te ma.
Te Maamaa: Ko te HPMC he 80 mata, 100 mata, 120 mata, ka pai ake te pai ka pai ake.
Tukunga: hoatu te HPMC ki roto i te wai kia hanga he colloid maramara, me te titiro ki tona tukunga.Ko te nui ake o te whakawhiti, ka iti ake nga matū kore e rewa i roto i te wai.Ko te tikanga, he pai ake te whakawhiti i roto i nga reactor poutū me nga reactors whakapae.He kino rawa atu i roto i te reactor poutū, engari e kore e taea te whakamarama he pai ake te kounga o te hua i mahia e te reactor poutū i to te reactor whakapae.
Te taumahatanga: I te nuinga o te waa, na te nui o te hydroxypropyl, he pai te paanga o te pupuri wai.
