Tarisa pane Cellulose ethers

Nzira yekushandisa sei HPMC?

Hydroxypropyl methylcellulose (HPMC) yakajairika semi-synthetic cellulose derivative inoshandiswa zvakanyanya mumishonga, kuvaka, chikafu nemimwe minda.

(1) Basic maitiro eHPMC

HPMC ihupfu chena inonyungudika mumvura kuita viscous colloidal solution. Iyo ine yakanaka adhesion, kugadzikana uye thickening zvivakwa, uye inogona kugadzira firimu rakajeka. Zvimiro zveHPMC zvinoenderana nedhigirii remethylation uye hydroxypropylation, saka kune akasiyana zvirevo uye mashandisiro.

(2) Nzvimbo huru dzekushandisa uye kushandiswa kweHPMC

1. Indasitiri yemishonga

a. Semutakuri wezvinodhaka uye anogara achiburitswa mumiririri

HPMC inowanzoshandiswa seyakagadziriswa-yakaburitswa mugadziriro yezvinodhaka. Mumapiritsi nemakapisi, HPMC inogona kugadzira firimu rakagadzikana uye kudzora mwero wekuburitswa kwezvinodhaka. Kana yashandiswa, HPMC inosanganiswa nemishonga yemishonga. Mushure mekutora piritsi kana kuzadza iyo capsule, HPMC inogona zvishoma nezvishoma kuburitsa mushonga mudumbu remudumbu.

b. Somubhainda

Mukugadzira piritsi, HPMC inowanzoshandiswa sebhainda. Kana yakasanganiswa nezvimwe zvinoshandiswa, inogona kuvandudza simba uye kugadzikana kwehwendefa.

c. Semunhu anomisa basa

Mumishonga yemvura, HPMC inogona kudzivirira zvinobudirira zvigadzirwa zvemushonga kubva pakugadzirisa, nekudaro kuchengetedza kufanana kwemushonga.

2. Indasitiri yekuvaka

a. Semukobvu wesamende dhaka

Mukuvaka, HPMC inoshandiswa kusanganisa simende, jecha uye zvimwe zvinhu kusimudzira kunamatira uye kuita kwekuvaka kwedhaka. Inogona kuvandudza kuchengetwa kwemvura kwedhaka uye kudzivirira kuti irege kuoma nokukurumidza, nokudaro kuwedzera nguva yekushanda yedhaka.

b. Sekuwedzera kwekunamatira tile

HPMC inogona kushandiswa sechinhu chinowedzera chekunamira kwetairi kuti iwedzere kunamatira uye kuita kwekuvaka kweanonamira uye kudzivirira zvidhinha kubva pakudonha.

3. Indasitiri yezvokudya

a. Sechikafu chekudya uye stabilizer

HPMC inowanzoshandiswa sechikafu muzvokudya, zvakadai sejamu, jellies uye zvinwiwa. Inogona kuwedzera viscosity yechigadzirwa uye kuchengetedza kugadzikana kwechigadzirwa.

b. Semufirimu wechikafu wekare

HPMC inogona kushandiswa mukugadzira chikafu chekurongedza firimu kugadzira firimu rakajeka kuchengetedza chikafu.

4. Cosmetics Indasitiri

a. Semukobvu wezvizoro

HPMC inowanzoshandiswa muzvizoro, zvakadai sekuchenesa chiso, mafuta eganda, nezvimwewo, semushonga wekuvandudza mararamiro uye kugadzikana kwechigadzirwa.

b. Semunhu aimbove firimu

HPMC inogona kugadzira firimu rakajeka uye rinoshandiswa seyaimbova firimu muzvigadzirwa zvekuchengetedza ganda, senge maski kumeso.

(3) Chengetedzo yekushandiswa kweHPMC

Solubility

The dissolution rate yeHPMC inokanganiswa nekupisa uye nekukurudzira mamiriro. Ita shuwa kuti musanganiswa unomutswa zvakaenzana panguva yekunyunguduka kudzivirira kusangana.

Concentration control

Gadzirisa huwandu hweHPMC zvinoenderana nezvinodiwa zvekushandisa. Mukugadzirira kwemishonga, kunyanya kuwandisa kunogona kukanganisa kusunungurwa kwechirwere; muzvinhu zvekuvaka, kunyanya kuderera kunogona kukonzera kusakwana kwekushanda kwezvinhu.

Kuchengetedza mamiriro

HPMC inofanira kuchengetwa munzvimbo yakaoma, inotonhorera, kudzivisa kupisa kwepamusoro uye hunyoro kuchengetedza kugadzikana uye kushanda kwayo.

Kugarisana

Paunenge uchishandisa HPMC, kuenderana kwayo nezvimwe zvinongedzo zvinofanirwa kutariswa, kunyanya kana ichishandiswa mumishonga uye chikafu, kuve nechokwadi chekuti hapana maitiro akashata anoitika.

HPMC inogadzirwa zvakasiyana-siyana cellulose ine huwandu hwakawanda hwekushandisa. Kubva kumishonga kusvika pakuvaka, chikafu kusvika kune zvekuzora, HPMC yakasarudzika zvivakwa zvinoita kuti iite basa rakakosha mumhando dzakasiyana dzezvigadzirwa. Paunenge uchiishandisa, zvinodikanwa kuti usarudze akakodzera maratidziro uye kutarisisa zvinoenderana nezvinodiwa zvekushandisa, uye teerera kune solubility kwayo uye mamiriro ekuchengetedza kuti uve nechokwadi chekushanda uye kugadzikana kwechigadzirwa.
