Hydroxypropyl1

Hydroxypropyl methyl cellulose (HPMC), te rauemi matapūtau, ka taea te miro para, te penupenu rakau ranei. He mea tika ki te parapara i mua i te wa ranei o te mahi whakangao. Ko te pulverization ka mahia e te kaha miihini. Whakamotitia te hanganga whakahiato o nga rauemi mata cellulose hei whakaiti i te tioata me te tohu polymerization me te whakanui ake i te waahi o te mata, na reira ka pai ake te urunga me te kaha tauhohenga matū o nga reagents ki nga roopu hydroxyl e toru i runga i te turanga mowhiti hukahuka macromolecular cellulose.

Hydroxypropyl methyl cellulose (HPMC)ka whakamahia hei taputapu mata hei whakaputa hinu, ka taea te mohio ki te whakamahi o te huka katoa, te whakapai ake i te tere o te whakamahi o nga rauemi mata, te whakaiti i te toenga o te tïpako i roto i te hupa fermentation, me te whakaiti i te utu mo te maimoatanga wai para. Ko nga ahuatanga omethyl cellulosehe pai ki te arotautanga o te puranga, te whangai-whanga me nga tukanga FERMENTATION tonu, te karo i te raupapa o nga raruraru penei i te whakahaere i te hanganga o te reo me te reiti waimeha; i te wa ano, he pai hoki ki te whakahaere i te tukanga FERMENTATION. No te mea nga taonga ohydroxypropyl methyl cellulose (HPMC)he rite ki etahi atu ethers wairewa-wairewa, ka taea te whakamahi hei kaihoko kiriata-whakaahua, thickener, emulsifier me te stabilizer i roto i te latex coatings me te wai-wairewa wai-wairewa whakakikorua wāhanga, ka taea ki te hanga paninga Ko te kiriata he pai te aukati abrasion, te taumata. nga taonga me te piri, kua pai ake te maataki o te mata, te pumau ki te waikawa me te kawakawa, me te hototahi ki nga poaka konganuku.

Hydroxypropyl methyl cellulose (HPMC)he painga pai hei whakapouri mo nga paninga polyvinyl acetate ma te wai ma. Te tohu whakakapinga oether celluloseka piki ake, ka kaha ake ano te atete ki te huakita me te horo.

Ahakoa ko te kaupapa o te whakahiatotanga o te hydroxypropyl methylcellulose (HPMC) ehara i te mea uaua, ko te whakamaaramatanga, te kuru o te rauemi mata, me te whakamaaramatanga. Ko nga momo taiao o te whakamaarama, te whakaora whakarewa, te wehenga centrifugal, te horoi me te whakamaroke he maha nga hangarau matua me te matauranga nui.

Mo nga momo hua rereke, kei ia taiao nga tikanga whakahaere hou, penei i te pāmahana, te wa, te pehanga me te mana rere rawa. Ko nga taputapu awhina me nga taputapu whakahaere he tohu pono me te whai hua mo te kounga hua me te punaha whakaputa pono.

āhuatanga hua ohydroxypropyl methyl cellulose:

1. Nga Taonga: Ko tenei hua he paura ma, he hongi, he reka, he kore paitini.

2. Te painga o te pupuri wai: Na te mea ka taea e tenei hua te tango i te wai he maha nga wa taumaha atu i a ia ano. Kia mau tonu te pupuri wai i roto i te kumete, te gypsum, te peita me etahi atu hua.

3. Ka taea te whakakore i tenei hua ki roto i te wai matao hei hanga i te whakarewa maataata.

4. Te whakakorenga i roto i nga whakarewa pararopi: Na te mea kei roto i etahi momo ira hydrophobic, ka taea te rewa tenei hua ki etahi whakarewa pararopi, ka taea hoki te rewa i roto i nga whakarewa whakauru o te wai me te mea pararopi.

5. Te parenga tote: I te mea ko tenei hua he katote-kore me te polyelectrolyte-kore, he ahua pumau i roto i nga wairewa wai o nga tote whakarewa me nga electrolyte pararopi. Mēnā he nui rawa te electrolyte, ka puta pea he wairere, he rerenga ranei.

6. Mahi mata: Ko te wairewa wai o tenei hua he mahi mata.
