Hydroxypropyl methylcellulose (HPMC) nehypromellose zvinhu zvakafanana, uye mazwi aya anowanzo shandiswa achichinjana. Aya mazita akaomarara emhando dzakajairika dzemapolymers akavakirwa pa cellulose ane mashandisirwo akasiyana-siyana mumaindasitiri akasiyana-siyana anosanganisira mishonga, chikafu uye zvizoro.
1. Magadzirirwo emakemikari uye kuumbwa:
Hydroxypropylmethylcellulose (HPMC) imhando yakagadzirwa ye cellulose, iyo polymer yechisikigo inowanikwa mumadziro emasero emiti. Maumbirwo emakemikari eHPMC anowanikwa nekuunza mapoka ehydroxypropyl nemethyl zvichibva pa cellulose. Boka rehydroxypropyl rinoita kuti cellulose isununguke zvakanyanya mumvura, uye boka remethyl rinowedzera kugadzikana kwayo uye rinoderedza reactivity yayo.
2. Maitiro ekugadzira:
Kugadzirwa kwehydroxypropyl methylcellulose kunosanganisira kurapa cellulose nepropylene oxide kuti iunze mapoka ehydroxypropyl uye wozoshandisa methyl chloride kuti iwedzere mapoka emethyl. Dhigirii rekutsiva (DS) rehydroxypropyl nemethyl rinogona kugadziriswa panguva yekugadzira, zvichikonzera mhando dzakasiyana dzeHPMC dzine hunhu hwakasiyana.
3. Hunhu hwemuviri:
HPMC ipfuu chena kusvika pakuva chena zvishoma, haina hwema uye haina kunaka. Hunhu hwayo hwepanyama, hwakadai sekusimba uye kunyungudika, zvinoenderana nehuwandu hwekutsiva uye huremu hwemamorekuru epolymer. Mumamiriro ezvinhu akajairwa, inonyungudika nyore nyore mumvura, zvichiita mhinduro yakajeka uye isina ruvara.
4. Zvinangwa zvekurapa:
Imwe yenzira huru dzekushandisa HPMC iri muindasitiri yemishonga. Inoshandiswa zvakanyanya semushonga unobatsira pakurapa uye inoita mabasa akasiyana-siyana mukugadzira mishonga. HPMC inowanzo kuwanikwa mumhando dzakasimba dzemushonga dzakadai semapiritsi, makapisi, nemapiritsi. Inoshanda semushonga unosunga, unobvisa utachiona, uye unodzorwa, zvichibatsira mukugadzikana kwese uye kuwanikwa kwemushonga.
5. Basa mukugadzirira kusunungurwa kunodzorwa:
Kugona kweHPMC kugadzira majeli mumvura kunoita kuti ive yakakosha mumishonga inoburitswa nemutemo. Nekuchinja hunhu hwemajeli uye hunhu hwekugadzira gel, masayendisiti emishonga anogona kudzora huwandu hwekuburitswa kwezvinhu zvinoshanda, nokudaro vachiita kuti mushonga ushande kwenguva refu.
6. Kushandiswa muindasitiri yechikafu:
Muindasitiri yezvekudya, HPMC inoshandiswa semuchina wekuomesa, wekusimbisa muviri uye wekusimbisa muviri. Inovandudza magadzirirwo ezvekudya zvakasiyana-siyana, kusanganisira masosi, soup nezvigadzirwa zvemukaka. Pamusoro pezvo, HPMC inoshandiswa mukubika zvisina gluten kuti iwedzere chimiro uye hunhu hwekunyorovesa hwezvigadzirwa zvisina gluten.
7. Zvishandiso zvekuvaka:
HPMC inoshandiswa muindasitiri yekuvaka muzvigadzirwa zvakaita sematiles anonamira, maplaster akavakirwa pasimende uye zvinhu zvakagadzirwa negypsum. Inovandudza kugona kwayo kugadzikiswa, kuchengetedza mvura uye hunhu hwekunamira hwezvigadzirwa izvi.
8. Zvizoro uye zvigadzirwa zvekuchengetedza muviri:
Hypromellose chinhu chinowanikwawo muzvizoro uye zvigadzirwa zvekuchengetedza muviri. Inoshandiswa mumakirimu, mafuta ekuzora uye shampoos nekuda kwekukora kwayo uye kugadzikana. Pamusoro pezvo, inobatsira kuvandudza magadzirirwo uye kunzwa kwechigadzirwa chose.
9. Kuputira firimu mumishonga:
HPMC inoshandiswa zvakanyanya muindasitiri yemishonga yekupenda mapiritsi. Mapiritsi akaputirwa nefirimu anopa chitarisiko chakanaka, anovhara kuravira uye anodzivirira kubva kuzvinhu zvinokonzeresa zvakatipoteredza. Mafirimu eHPMC anopa kupenya kwakatsetseka uye kwakafanana, zvichivandudza mhando yese yemushonga.
13. Mhedziso:
Hydroxypropyl methylcellulose (HPMC) uye hypromellose zvinoreva cellulose-based polymer imwecheteyo ine mashandisirwo akasiyana-siyana mumishonga, chikafu, zvizoro, uye kuvaka. Hunhu hwayo hwakasiyana, hwakadai sekunyunguduka, kugadzikana uye kuora kwezvinhu zvipenyu, hunobatsira mukushandiswa kwayo kwose kwose. Kuchinja-chinja kweHPMC mumaindasitiri akasiyana kunoratidza kukosha kwayo sechinhu chinoshanda zvakawanda, uye kuramba ichishandiswa.kutsvaga nekugadzira zvinogona kuwana mamwe maapplication mune ramangwana.
Ongororo iyi yakazara ine chinangwa chekupa kunzwisisa kwakadzama kwehydroxypropyl methylcellulose nehypromellose, kujekesa kukosha kwazvo muminda yakasiyana-siyana, uye kujekesa basa razvo mukuumba zvigadzirwa zvakawanda uye mafomura.
