I-Hydroxypropyl Methylcellulose (HPMC) ku-Sanitizer Yesandla

I-Hydroxypropyl Methylcellulose (HPMC)iyi-ether ye-cellulose engeyona i-ionic esetshenziswa kakhulu, esetshenziswa kabanzi embonini yamakhemikhali yansuku zonke, ikakhulukazi emikhiqizweni yokuhlanza efana nesihlanzi sezandla, isihlanzi sobuso, i-shampoo, ijeli yokugeza, njll. Imisebenzi yayo eyinhloko ifaka phakathi ukuqina, ukumiswa okuzinzile, ukuthambisa okwenza ifilimu, kanye nokuthuthukisa ukuthinta.

1. Izakhiwo eziyisisekelo ze-HPMC

I-HPMC iyi-polymer encibilika emanzini eyenziwe nge-cellulose yemvelo futhi eguquliwe ngamakhemikhali. Iyakwazi ukuhambisana kahle nezinto eziphilayo kanye nokubola kwazo. Iyi-polymer engeyona i-ionic engancibilika emanzini abandayo ukuze yakhe isixazululo se-colloidal esibonakalayo nesiqinile. Ngenxa yokuncibilika kwayo okuhle, ukusebenza kokulawula i-viscosity kanye nokuphepha okuphezulu, isetshenziswa kabanzi ekudleni, emithini kanye nasemasimini amakhemikhali ansuku zonke.

2. Indima eyinhloko ye-HPMC ekuhlanzeni izandla

2.1. Isiqinisi

Umsebenzi oyinhloko we-HPMC ukusetshenziswa njengesithambisi. Isihlanzisi sezandla sidinga i-viscosity efanele ukuze kungabi lula ukusilahla, kube lula ukusilawula nokuyisebenzisa uma sisetshenziswa abasebenzisi. I-HPMC ingakhuphula ngempumelelo i-viscosity yomkhiqizo ngamanani aphansi, okwenza isihlanzisi sezandla sibe nezakhiwo ezifanele ze-rheological, sithuthukise ukuthinta kwaso kanye nolwazi lomsebenzisi.

2.2. Izinzisi kanye nama-ejenti okumisa

Izihlanzi zezandla zingase ziqukathe izingxenye ezingafani njengamafutha abalulekile, izithako zokulwa namagciwane, izinhlayiya ze-microcapsule noma ama-pearlescent agents. I-HPMC inamandla amahle okuqina kwe-emulsification kanye nezakhiwo zokumiswa, ezingavimbela lezi zingxenye ukuthi zingahlukani noma zingene, futhi zithuthukise ukuqina kanye nokufana kokubukeka kwezihlanzi zezandla.

2.3. Thuthukisa ukugeleza kanye nolwazi lokusebenzisa

Ngenxa yezakhiwo zoketshezi lwe-pseudoplastic zesisombululo se-HPMC (ukunciphisa ukugunda), sinomswakama ophezulu ngaphansi kwamandla aphansi okugunda, kodwa umswakama uyancipha lapho umsebenzisi ecindezela futhi ekhuhla, okwenza kube lula ukuyisebenzisa ngaphandle kokushiya umuzwa wokunamathela. Lesi sici sihambisana kakhulu nokubekwa komkhiqizo kwezihlanzi-zandla “njengokulula ukuzisebenzisa futhi okukhululekile ukuzisebenzisa”.

2.4. Ukwakheka kwefilimu kanye nokuthambisa

I-HPMC inezakhiwo zokwakha ifilimu futhi ingakha ifilimu encane enomoya omuhle ongenela ebusweni besikhumba, edlala indima ekuvikeleni nasekuvaleni amanzi. Ingaphinde ithuthukise ukuthamba kwesikhumba futhi isize ekunciphiseni ukucasuka kwensipho esikhumbeni. Ingenye yezithako ezivame ukusetshenziswa ekuthambiseni imikhiqizo yokuhlanza emnene.

2.5. Thuthukisa ukubukeka komkhiqizo

Ukubonakala okuphezulu kuyindlela ethengiswa kakhulu yokuhlanza izandla. Ngemva kokuba i-HPMC incibilikile, yakha ikhambi elicacile nelisobala, elingathinti ukubukeka komkhiqizo. Ingasetshenziswa futhi nama-ejenti e-pearlescent ukuthuthukisa umphumela wokubona nokuthuthukisa umuzwa wekhwalithi ephezulu womkhiqizo.

3. Indlela i-HPMC esetshenziswa ngayo ekuhlanzeni izandla

Kwifomula ye-sanitizer yezandla, i-HPMC ivame ukungezwa ngesimo sempuphu. Ukuze kuqinisekiswe ukuthi incibilike ngokuphelele futhi kuvinjelwe ukuhlangana, kunconywa ukuthi uyisakaze emanzini abandayo bese uyixuba kahle, bese uyifudumeza ukuze kusheshiswe inqubo yokuncibilika. Inani elivame ukusetshenziswa lokwengeza lingu-0.1% ~ 0.8%, kuye ngokuthi izinga le-viscosity elidingekayo kanye nomphumela wokubambisana kwezinye izithako kufomula.

4. Izinzuzo zokusebenzisa i-HPMC

Iphephile futhi ayicasuli: I-HPMC iyi-non-ionic cellulose derivative, ayinabo ubuthi futhi ayinaphunga, ayinakho ukucasuka okukhulu esikhumbeni nasemahlweni, futhi ifaneleka emikhiqizweni esetshenziswa yizingane noma isikhumba esizwelayo.

Okubolayo: Kuyizinto zokusetshenziswa ezingangcolisi imvelo ezivela ngokwemvelo, ezihambisana nomkhuba wokuthuthukiswa kwezimonyo eziluhlaza.

Ukuhambisana okuqinile: Kungahambisana kahle nama-surfactants ahlukahlukene, ukunambitheka, izithako zokugcina kanye nezinye izithako, futhi akuthambekeli ekungazinzini kwefomula.

Izindleko ziyalawuleka: Uma kuqhathaniswa nezinye izithambisi zokwenziwa ze-polymer, i-HPMC iyasebenza kahle futhi iyisisombululo esingabizi futhi esizinzile.

5. Izinyathelo zokuqapha kanye nezinselele

5.1. Indlela yokuncibilikisa idinga ukulawulwa ngokufanele

Uma ukusebenza kungafanele, izinkinga ezifana nokuhlangana kanye nokungancibiliki kahle kungenzeka zivele, okuthinta ikhwalithi yomkhiqizo. I-HPMC kumele yengezwe kancane kancane uma ixutshwa futhi incibilikiswe ngokuphelele ekushiseni okufanele.

5.2. Ububanzi obuthile bokuzivumelanisa nezimo ne-pH

I-HPMC izinzile uma inani le-pH liphakathi kuka-4 no-11. Uma ifomula ye-sanitizer yesandla iqukethe i-asidi enamandla noma izingxenye ze-alkali ezinamandla, kufanele kuqashelwe ukuthi ukuqina kwayo kanye nomphumela wokugcinwa kwe-viscosity kufanele kuqashelwe.

5.3. Ukuzwela kwezinga lokushisa

Ukuchachamba kwe-HPMC kuzoncipha emazingeni okushisa aphezulu. Uma ifomula ye-sanitizer yesandla idinga ukuhlanza ngokushisa okuphezulu, ukuqina kwayo kokushisa kufanele kuhlolwe.

Ukusetshenziswa kwe-HPMCI-sanitizer yesandla ibonisa izidingo ezimbili zemikhiqizo yamakhemikhali yansuku zonke yesimanje "yokusebenza okuphezulu + ukuphepha okuphezulu". Ayigcini nje ngokuthuthukisa ukuthungwa nokusebenza komkhiqizo, kodwa futhi icabangela ukuvikelwa kwemvelo kanye nentuthuko eqhubekayo. Njengoba izidingo zabathengi zekhwalithi yemikhiqizo yokuhlanza ziqhubeka nokukhula, i-HPMC, njengezinto zokusetshenziswa ezisebenza ngezindlela eziningi, eziphephile nezizinzile, izodlala indima ebaluleke kakhulu kuma-sanitizer ezandla kanye neminye imikhiqizo yokuhlanza nokunakekela isikhumba. Ezinkampanini zamakhemikhali zansuku zonke, ukusetshenziswa kwesayensi nokunengqondo kwe-HPMC akugcini nje ngokuthuthukisa ukuncintisana komkhiqizo, kodwa futhi kusize ekudaleni isithombe somkhiqizo esikhangayo kakhudlwana.
