Hydroxypropyl Methylcellulose ke Eng ka Kaho?
Hydroxypropyl methylcellulose ke ether ea cellulose e seng ea ionic e nkiloeng ho cellulose ea tlhaho 'me e fetotsoe ka lik'hemik'hale hore e qhibilihe ka metsing. Litsamaisong tsa kaho, HPMC e sebetsa haholo-holo e le:
- Moemeli oa ho boloka metsi
- Mohlophisi oa sethibela-mafu le rheology
- Sesebelisoa sa ho ntlafatsa bokgoni ba ho sebetsa
- Moemeli oa ho loantša linyeoe
- Sesebelisoa sa ho atolosa nako ea ho buleha
- Ntlafatsa botsitso
Hobane e sebetsa ka katleho maemong a tlase a tekanyo, HPMC e nkoa e le tlatsetso e sebetsang hantle haholo thepa ea kaho ea motsoako o omileng.

Tšebeliso e Molemohali ea Hydroxypropyl Methylcellulose Thepang ea Kaho
1. Likhomaretsi tsa Lithaele
E 'ngoe ea lisebelisoa tsa bohlokoa ka ho fetisisa tsa hydroxypropyl methylcellulose ke ho mekhoa ea sekhomaretsi sa thaeleHPMC e thusa ho laola ho teteana le ho boloka metsi, e netefatsa hore samente e na le metsi a lekaneng le hore lithaele li tlamahane hantle.
- E ntlafatsa ho hanyetsa ho thella
- E eketsa nako ea ho bula
- E ntlafatsa ho ata ha eona
- E fokotsa ho oa ha lithaele holim'a libaka tse otlolohileng
- E ntlafatsa matla a ho qetela a tlamo
Mefuta e tloaelehileng ea tekanyo: 0.2%–0.5% ea boima ba motsoako o omileng.
2. Seretse se Omileng sa Motsoako
Mekhoeng ea seretse se omileng se kopantsoeng, HPMC e sebelisoa ho tsitsisa motsoako le ho ntlafatsa ts'ebetso ea kaho. E netefatsa kabo ea metsi e ts'oanang 'me e fokotsa ho tsoa mali le karohano.
- Tshebetso e betere ea ho thapolla teropo
- Kotsi e fokotsehileng ea ho petsoha
- Kutlwano e ntlafetseng
- Ho phekola ka mokhoa o ts'oanang haholoanyane
3. Putty ea Leboteng le Kobo e Khutšoanyane
Lihlahisoa tsa putty le skim coat li itšetlehile ka HPMC bakeng sa ts'ebeliso e boreleli le boleng ba ho qeta bokaholimo. Khetho e nepahetseng ea viscosity e thusa ho leka-lekanya ho sebetsa hantle le ho hanyetsa ho oa.
- Tshebetso e boreleli ea ho phunya
- Ho batalatsa bokaholimo ho ntlafalitsoe
- Phofo e fokotsehileng
- Ho boloka metsi hantle nakong ea ho hloekisa
4. Sesetara sa samente le ho etsa litšoantšo
Litšebelisong tsa plaster le rendering, hydroxypropyl methylcellulose e ntlafatsa 'mele oa seretse mme e fokotsa tahlehelo ea ho khutla ha ho fafatsoa kapa ho sebelisoa ka letsoho.
- Ho khomarela mabota le siling hamolemo
- Litšila tse fokotsehileng tsa thepa
- Ho pompa ho ntlafetseng
- Khanyetso e matlafalitsoeng ea mapetso
5. Metswako e Itekanetseng
Leha e sebelisoa maemong a tlase, HPMC e thusa ho leka-lekanya viscosity litsamaisong tse iketsang, e leng se thusang ho laola phallo ntle le karohano e feteletseng.
- Taolo ea phallo
- Ho emisoa ha likaroloana
- Phokotso ea sekoli sa bokaholimo
6. Lihlahisoa tse Thehiloeng ho Gypsum
Li-plaster tsa gypsum le metsoako e kopaneng li sebelisa HPMC ho laola tlhoko ea metsi le ho ntlafatsa litšobotsi tsa ho sebetsana le metsi.

| Ho ikamahanya le maemo | Viscosity e tlase ho isa ho e mahareng |
Malebela a ho Lokisa bakeng sa Tshebetso e Ntle
- Kenya HPMC nakong ea ho kopanya ka omileng bakeng sa ho hasana hantle
- Qoba ho eketsoa ka ho toba ka metsing a chesang
- Bapisa sehlopha sa viscosity le mokhoa oa ho sebelisa
- Leka ho boloka metsi le nako ea ho bula hammoho
- Fetola tekanyo ho latela ho hlophisoa ha lehlabathe le mofuta oa samente
