I-HPMC (Hydroxypropyl methylcelcelcelsulose) Ngaba isifo esibalulekileyo esihleliweyo sisetyenziswa ngokubanzi kwizinto zokwakha. Imisebenzi yayo ephambili ibandakanya ukuphucula ukugcinwa kwamanzi kodaka, ukuphucula ukusebenza nokuphucula ukunganyangeki kwe-rack. Ukuhle kwe-chancel®hpmc yenye yeeparamitha ezibalulekileyo zomsebenzi, ezichaphazela ngokuthe ngqo ukugcwala kwayo kunye nokusasazwa koludaka kunye nefuthe lokuphuculwa kwalo kwipropati yodaka.
1. Inkcazo ye-HPMC
Ubungakanani be-HPMC buhlala bubonakaliswa ngokwemigangatho ye-paricle ye-paricle yamasuntswana okanye ipesenti yokudlula kwi-sieve ethile. I-HPMC amasuntswana anombuso obukhulu zincinci kwaye ube nendawo enkulu yomphezulu; I-HPMC amasuntswana anombuso obukhulu zikhulu kwaye abe nendawo encinci yomhlaba. Ubuhle bunefuthe elibonakalayo kwixabiso lokuchitha, ukuhambisa ukufana nokunxibelelana kwe-HPMC ngamasuntswana.
2. Isiphumo sokugcinwa kwamanzi
Ukugcinwa kwamanzi sisibonisi esibalulekileyo sokusebenza kodaka, esichaphazela ngokuthe ngqo ukusebenza kunye nomgangatho emva kokukhanya. Ukuphakama kwe-HPMC, kokukhohlisa amasuntswana asebusweni, onokwenza umqobo ogciniweyo wamanzi, ngaloo ndlela ukuphuculwa kokugcinwa kwamanzi kodaka. Ukongeza, i-HPMC ye-HPMC ilungile inyibilikisa ngokukhawuleza kwaye ingagcina amanzi ngaphambili, enobuchule obufanelekileyo kubushushu obuphakathi okanye ukwakhiwa kwamanzi.
Nangona kunjalo, ukulunga ngokugqithisileyo kunokubangela i-HPMC ukuba iphazamise xa inxibelelana ngokukhawuleza namanzi, echaphazela isabelo sayo kudaka, ngaloo ndlela kuncitshiswa umthombo wokugcinwa kwamanzi. Ke ngoko, iimfuno zokusetyenziswa kwesicelo kufuneka ziqwalaselwe ngokufanelekileyo xa ukhetha ukulunga kwe-HPMC.
3. Ifuthe ekusebenzeni
Ukusebenza kubhekisa kwintsebenzo yokwakha yodaka, enxulumene kakhulu nolwelo neThokotroli kodaka. I-HPMC amasuntswana enomtsalane ophakamileyo angenza inkqubo ye-colloid efanayo kwi-Colloid emva kokunyibilikisa, enceda ekuphuculeni udaka kunye nokungasebenzi kodaka, oko kuphucula ukusebenza. Ingakumbi ukwakhiwa komatshini, i-HPMC entle ye-HPMC inokukunciphisa ukunganyangeki okutshintshileyo kunye nokuphucula ukusebenza kakuhle.
Ngokuchasene noko, ngenxa yenqanaba lokuchithwa kancinci kwamasuntswana e-HPMC ngokulunga, udaka lusenokuba lolona tyelelo lokonwaba kwinqanaba lokuqala lokuxuba, kuchaphazela ukusebenza ngokwakhiwa. Ukongeza, i-HPMC enamasuntswana amakhulu isenokuhanjiswa ngendlela engalinganiyo elulalweni, echaphazela ukusebenza ngokupheleleyo.
4. Impembelelo ekuchanyoneni kwe-crack
Ukunganyangeki kuchaphazeleka ikakhulu kukomisa i-shrinking kunye nokusasazeka kwangaphakathi kokufana. I-HPMC enomtsalane omkhulu unokusasazwa ngakumbi kuludaka ukuba lube yifilimu eqhubekayo yeselselose, ilithintela inqanaba lokuphuma kwamanzi kwaye linciphise ukuncitshiswa kodaka kodaka, ngokufezekileyo ukuphucula ukunganyangeki kodaka.
Kwelinye icala, i-HPMC enobukhulu obuphantsi ibeka iindawo ezigxile kuzo ngaphakathi kodaka ngenxa yokusasazeka okungekho mthethweni, kwaye ayinakho ukulawula ukonakala, kwaye inamandla okuqhekeka.
5. Isiphumo kumandla
Ukulunga kwe-HPMC kunefuthe ngokungathanga ngqo kumandla odaka. I-HPMC enomtsalane omkhulu ihlala inceda isamente kwi-hydrate ngakumbi ngenxa yokugcinwa kwamanzi kunye nokusasazeka, oko kuya kuphucula amandla okuqala kodaka. I-Nuincel®HPMM enobuthathaka obuphantsi bubuthathaka ekutshintshenisweni kunye nokusasazwa, okunokukhokelela ekungafundiniyo kwiindawo ezinomsebenzi wengingqi, ngaloo ndlela ichaphazela ukufana kwabantu abagulayo.
Kufuneka kuqatshelwe ukuba umxholo we-HPMC okanye ubuhle bunokuba nefuthe elibi kumandla, kuba isellulose ngokwayo inegalelo elilinganiselweyo kwiimpawu zodaka zodaka, kwaye kakhulu kuya kuphelisa umyinge we-avaregate kunye nesamente.
I-6. Ukuqwalaselwa kwezoqoqosho nezokwakha
Kwiiprojekthi zokwenyani, i-HPMC ephezulu ye-HPMC ihlala ibiza kakhulu, kodwa izibonelelo zayo zomsebenzi ziyabonakala, kwaye ilungele izihlandlo ezifunekileyo ekugcinweni kwamanzi kunye nokunganyangeki. Iimfuno zokwakha ngokubanzi, ukulunga kwe-HPMC ngokulinganisela kunokusenza ibhalansi phakathi kokusebenza noqoqosho.
I-HPMC Ngomkhwa ohlukileyo unefuthe elibonakalayo kwipropati yodaka. I-HPMC ephezulu ye-HPMC ihlala inentsebenzo ebalaseleyo malunga nokugcinwa kwamanzi, ukusebenza kunye nokunganyangeki, kodwa indleko iphezulu kwaye kunokubangela ukuba ingozi yenkqubo yokupheliswa; I-HPMC ye-HPMC iphantsi iphantsi ngexabiso, kodwa inomda wokuphuculwa kwentsebenzo. . Ukukhethwa kwengqondo kwe-Incencel®HPMMC ngokuhambelana neemfuno ezithile zokwakha sisicwangciso esibalulekileyo sokukwenza ukusebenzela ukuhombisa nokulawula.
