1. He aha te hydroxypropyl methylcellulose?
Hydroxypropyl methylcellulose (HPMC)he ether cellulose kore-ionic me te kino, e whakamahia nuitia ana i roto i nga taonga hanga whare, kai, rongoa, whakapaipai me etahi atu mara. Kei a ia nga mahi o te matotoru, te pupuri wai, te hanga kiriata, te honohono, te whakahinuhinu me te whakatārewatanga, a ka memeha ki roto i te wai hei hanga i te otinga maataata, whakawhiti marama ranei.
2. Whakamahinga noa me te whakamahi HPMC
Te mara hanga
Kei te whakamahia te HPMC ki nga taonga hanga whare penei i te kumete ciment, te paura putty, te whakapiri taera, aha atu:
Mahi: Whakanuia te mahi hanga, whakapai ake i te pupuri wai, whakaroa i te wa tuwhera, me te whakapai ake i nga mahi honohono.
Tikanga Whakamahi:
Tāpiri tika ki te kumete whakamaroke-whakaranuhia, ko te nui e taunakitia ana ko te 0.1%~0.5% o te papatipu o te sima, te tïpako ranei;
I muri i te tino whakaoho, whakauruhia he wai ka uru ki roto i te slurry.
Te ahumahi kai
Ka taea te whakamahi i te HPMC hei whakamatao, hei whakapumau me te whakaemi, ka kitea i roto i nga kai penei i te aihikirimi, te tiēre, te taro, aha atu.
Mahi: Whakapai ake i te reka, whakapumau i te punaha, me te aukati i te stratification.
Whakamahinga:
Whakarewa i roto i te wai matao, ka whakatikahia te inenga e taunakitia ana i waenga i te 0.2% me te 2% kia rite ki te momo kai;
Ma te whakawera, ma te whakakorikori miihini ranei ka tere te whakakore.
Te ahumahi rongoa
He maha nga wa e whakamahia ana te HPMC ki te paninga o te papa tarukino, te maaka papa tuku-papumau, te anga kapi ranei:
Mahi: hanga kiriata, whakaroa te tuku tarukino, me te tiaki i te mahi tarukino.
Whakamahinga:
Whakaritea ki te otinga me te kukū o te 1% ki te 5%;
Rehu riterite ki te mata o te papa kia hanga he kiriata angiangi.
Panuku
HPMCka whakamahia hei whakamaroke, hei whakapumau whakaehunga, hei kaihanga kiriata ranei, e whakamahia nuitia ana i roto i nga kanohi kanohi, hinu, aha atu:
Mahi: Whakapai ake i te kakano me te whakarei ake i te ahua o te hua.
Whakamahinga:
Tāpirihia ki te matrix whakapaipai i roto i te ōwehenga me te whakaoho rite;
Ko te inenga te tikanga 0.1% ki te 1%, whakaritea kia rite ki nga whakaritenga hua.
3. Tikanga whakakore HPMC
Ko te whakarewatanga o te HPMC ka tino pa ki te pāmahana wai:
He ngawari ki te memeha i roto i te wai matao ka taea te hanga i tetahi otinga rite;
Kare e rewa i roto i te wai wera, engari ka taea te marara ka hanga he colloid i muri i te whakamatao.
Ko nga waahanga whakakorenga motuhake:
Me ata tauhiuhia te HPMC ki te wai, karohia te riringi tika kia kore ai e pakaru;
Whakamahia he whakakorikori kia rite te uru;
Whakaritea te kukū otinga ina hiahiatia.
4. Whakatupato mo te whakamahi HPMC
Te whakahaere inenga: I roto i nga ahuatanga tono rereke, ka pa te inenga ki te mahi me te hiahia kia whakamatauria kia rite ki nga hiahia.
Nga tikanga rokiroki: Me penapena ki roto i te waahi makariri, maroke, whai hau kia kore ai te makuku me te wera nui.
Te whakamarumaru o te taiao: Ko te HPMC he koiora me te kore e poke i te taiao, engari me whakamahi tonu i runga i nga tikanga paerewa kia kore ai e ururua.
Whakamātautau hototahi: Ina taapirihia ki nga punaha uaua (penei i nga whakapaipai, rongoa ranei), me whakamatau te hototahi ki etahi atu kai.
5. Painga o HPMC
Kaore he paitini, he pai te taiao, he haumaru teitei;
Te whai kiko, te urutau ki nga momo whakaritenga tono;
He pai te pumau, ka taea te pupuri mahi mo te wa roa.
6. Nga raruraru noa me nga otinga
Raruraru whakahiatotanga: Kia tupato ki te taapiri kua marara i te wa e whakamahia ana, me te whakaoho i te wa ano.
Te wa roa o te rewa: Ka taea te whakamahi i te wai wera i mua i te whakamaoritanga, i te whakaoho miihini ranei hei whakatere i te whakakorenga.
Te paheketanga o te mahi: Kia tupato ki te waahi rokiroki kia kore ai te makuku me te wera.
Ma te whakamahi i te HPMC i runga i te matauranga me te whai whakaaro, ka taea te whakamahi i ona ahuatanga maha ki te whakarato otinga kounga teitei mo nga momo ahumahi.
