Kunzwisisa hydroxythyl cellulose (Hec):

1. Chemical chimiro:

HEC yakashongedzwa nekuita kwemasero neEndlyne oxide, zvichikonzera kuiswa kweiyo hydroxytHyl mapoka (-ch2ch2oh) kuCellulose Backbone.

Dhigirii rekutsiva Yakakwira DS kukosha kunotungamira kune kuwedzera mvura solubility uye yakaderera viscosity.

2. Zvivakwa:

Hec inokwira mumvura uye inoumba mhinduro dzakajeka, dzinoita kuti zviite kuti zviite zvakaringana zvekushandisa zvakaringana zvinoda kujeka mafomu.

Izvo zvinoratidzira maitiro epseudoplastic, zvichireva viscosity inoderera pasi peShear kushushikana, kubvumira kushandiswa kuri nyore uye kubata.

Iyo viscosity yemhinduro yehec inokurudzirwa nezvinhu zvakadai sekusimbirira, tembiricha, pH, uye kuvapo kwemazaru kana zvimwe zvinowedzera.

3. Zvikumbiro:

Pharmaceuticals: Hec inoshandiswa seanoshandiswa uye stabilizer mune yemuromo uye yepakati pharmaceuticucal fomu senge mafuta, uye kumiswa.

Cosmetics: Icho chinhu chinowanzoitika mune zvigadzirwa zvega zvega zvinosanganisira shampoos, marara, uye nemakiromita nekuda kwekuita kwayo uye anofungidzira zvivakwa.

Pendi uye kuungana: Hec inowedzerwa kupenda, majasi, uye anomanya kuomerera kudzora zvivakwa, kuvandudza kuyerera zvivakwa, uye kuwedzera kugadzirwa kwemafirimu.

Indasitiri yeChikafu: Muzvigadzirwa zvekudya, hec zvinoshanda sedhizimusi, stabilizer, uye emulsifier mune zvinhu senge sakita, zvipfeko, uye zvigadzirwa zvemukaka.

PH Kukosha kweHydroxyTHLYL Cellulose (Hec):

1. PH kuvimba:

Iyo pH yemhinduro ine hec inogona kukanganisa maitiro ayo uye kuita mune dzakasiyana siyana application.

Kazhinji, hec yakagadzikana pamusoro pehuremu hwakawandisa, kazhinji pakati pH 2 uye pH 12. Nekudaro, zvakanyanyisa PH mamiriro anogona kukanganisa zvivakwa zvayo uye kugadzikana.

2. PH Mhedzisiro pane viscosity:

Iyo viscosity yemhinduro dzehishiyo inogona kuve ph-inotsamira, kunyanya pakakwirira kana yakaderera ph kukosha.

Pedyo neakarerekera PH Range (PH 5-8), Hec mhinduro kazhinji inowanzo kuratidzira yavo yepamusoro viscosity.

Panguva yakaderera kwazvo kana yakakwira ph kukosha, iyo cellulose backbone inogona kuderera hydrolysis, zvichikonzera kuderera kwemisangano uye kugadzikana.

3. PH kugadzirisa:

Mukuumbwa uko pro kugadzirisa kunodiwa, buffers anowanzo shandiswa kuchengetedza iyo inodiwa pH range.

BUDAY BUFFERS yakadai seCitrate kana phosphate Buffers inoenderana neHec uye kubatsira kudzikisira zvivakwa zvayo mukati meiyo ph range.

4. Kuongorora kwekushandisa:

Vagadziri vanofanira kufunga nezve phenderedzwa yeHEC pamwe nezvimwe zvinoshandiswa mukuumbwa.

Mune zvimwe zviitiko, kugadzirisa kune iyo pH yekuumbwa kunogona kudikanwa kuti uwedzere kuita kwehwanda.

HydroxytHyl Cellulose (Hec) ishandara yemanyoreri ine yakapararira yekushandisa maindasitiri akasiyana siyana. Nepo iyo pH yakasimba inowanzoita rubants pamusoro pehuremu hwakawanda, PH ENDREMES zvinogona kukanganisa maitiro ayo uye kugadzikana. Kunzwisisa PH PH KEC kwakakosha pakugadzira zvigadzirwa zvinoshanda uye zvakagadzikana mumishonga yemishonga, cosmetics, pendi, zvinoshatisa, uye zvigadzirwa zvekudya. Nekufunga nezve phenderedzwa pH.
