IHydroxypropyl Methylcellulose (HPMC ngokufutshane) yi-semi-synthetic high molecular polymer esetyenziswa ngokubanzi kwiimveliso ezahlukeneyo zemizi-mveliso kunye nobomi bemihla ngemihla. Kwintsimi yezokucoca, i-HPMC ithe ngokuthe ngcembe ibe sisongezo esiyimfuneko ngokusekwe ekusebenzeni kwayo okugqwesileyo.
1. Iimpawu ezisisiseko ze-HPMC
I-HPMC yi-ether ye-cellulose engeyo-ionic eyenziwe kwiselulosi yendalo ngokuguqulwa kweekhemikhali. Inezi mpawu ziphambili zilandelayo:
Ukunyibilika kwamanzi: I-HPMC inokunyibilika emanzini abandayo kunye namanzi ashushu ukwenza i-translucent viscous isisombululo esicacileyo.
Uzinzo: Uzinzile kumajelo e-acidic okanye e-alkaline, awanaluvelwano kutshintsho lobushushu, kwaye inokumelana nobushushu kunye nokumelana nokunyibilika komkhenkce.
Ukuqina: I-HPMC inesiphumo esihle sokuqina, inokunyusa ngokufanelekileyo i-viscosity yenkqubo yolwelo, kwaye akukho lula ukuyidibanisa.
Ukwenziwa kwefilimu: I-HPMC inokwenza ifilim efanayo kumphezulu wokubonelela ngokhuseleko kunye neziphumo zodwa.
Zezi mpawu ezenza ukusetyenziswa kwe-HPMC kwizicoci zinesakhono esikhulu kunye nexabiso.
2. Indima ye-HPMC kwizicoci
Kwizinto zokucoca, imisebenzi ephambili ye-HPMC ibandakanya ukutyeba, ukuzinzisa, ukunqunyanyiswa, kunye nokwenziwa kwefilimu. Imisebenzi ethile yile ilandelayo:
Ukutyeba
Iidetergents zihlala zifuna ukugcina i-viscosity ethile ukuphucula amava omsebenzisi. I-HPMC inokwenza isakhiwo se-colloidal esizinzile ngokudibanisa namanzi ukunyusa i-viscosity ye-detergent. Kwizinto zokucoca ulwelo, i-viscosity efanelekileyo inokuthintela ukuhamba okugqithisileyo, okwenza imveliso ibe lula ukuyilawula nokusabalalisa xa isetyenziswa. Ukongeza, ukutyeba kunokunceda ekuphuculeni ukubamba kwesicoci, ukwenza kube lula xa kufakwe okanye kugalelwe, kwaye kuzise amava okusebenzisa ngokukhululekileyo.
Isizinzi
Izicoci zolwelo zihlala zinezithako, iziqholo, ibala kunye nezinye izithako. Ngexesha lokugcinwa kwexesha elide, ezi zithako zinokuthi zihlulwe okanye ziboliswe. I-HPMC ingasetyenziswa njengesizinzisi ukunqanda ukwenzeka kwestratification. Yenza isakhiwo sothungelwano esifanayo, ifake kwaye isasaze ngokulinganayo izithako ezahlukeneyo, kwaye igcine ukufana kunye nokuzinza kwexesha elide le-detergent.
I-arhente exhomayo
Amanye amasuntswana aqinileyo (anjengamasuntswana abrasive okanye ezinye izithako zokuphelisa ungcoliseko) adla ngokudityaniswa kwizicoci zale mihla. Ukuze kuthintelwe ezi amasuntswana ukuhlalisa okanye aggregating kulwelo, HPMC njenge arhente yokuxhoma ngokusebenzayo ukunqumamisa amasuntswana eqinileyo kulwelo medium ukuqinisekisa ukwabiwa iyunifomu amasuntswana ngexesha lokusetyenziswa. Oku kunokuphucula ubuchule bokucoca ngokubanzi bemveliso kwaye iqinisekise ukuba inokusebenza ngokuqhubekayo rhoqo xa isetyenziswa.
I-arhente yokwenza ifilimu
Iipropati zokwenza ifilimu ye-HPMC iyenza ibe yodwa kwezinye izicoci ezikhethekileyo. Umzekelo, kwezinye izinto ezithambileyo zelaphu okanye i-dishwasher detergents, i-HPMC inokwenza ifilimu ekhuselayo kumphezulu emva kokucoca, iphucula ukubengezela komphezulu wento ngelixa inciphisa intsalela yamabala okanye amabala amanzi. Le filimu inokuthi isebenze njengento yodwa yokuthintela umphezulu wento ekudibaneni ngokugqithiseleyo kunye nendalo yangaphandle, ngaloo ndlela yandisa ukuqina kwesiphumo sokucoca.
I-Moisturizer
Kwezinye iimveliso zokuhlamba, ngakumbi isepha yesandla okanye iimveliso zokuhlambela ezidibana ngokuthe ngqo nolusu, i-HPMC inesiphumo sokuthambisa. Inokukunceda ukunciphisa ukulahlekelwa kwamanzi ngexesha lenkqubo yokuhlamba, ngaloo ndlela ugweme ulusu olomileyo. Ukongeza, inokuzisa nefuthe elithambileyo lokukhusela, ukwenza ulusu lube thambile kwaye lube lula.
3. Ukusetyenziswa kwe-HPMC kwiintlobo ezahlukeneyo zezicoci
Izicoci zolwelo
I-HPMC isetyenziswa kakhulu kwizicoci zolwelo, ngakumbi kwiimveliso ezifana nezicoci zempahla kunye nezicoci zokuhlamba izitya. Iyakwazi ukulungelelanisa i-viscosity yee-detergents kunye nokwandisa ukusasazeka kunye namava okusebenzisa iimveliso. Ukongeza, i-HPMC inyibilika ngokuzinzileyo emanzini kwaye ayichaphazeli isiphumo sokucoca i-detergents.
Izicoci zezandla kunye neejeli zeshawa
I-HPMC ikhona njengento etyebisayo kunye neyokuthambisa kwiimveliso zokhathalelo lomntu ezifana nezicoci zezandla kunye neejeli zeshawa. Ngokwandisa i-viscosity yemveliso, i-detergent ayilula ukukhupha izandla, ukuphucula ukusetyenziswa kwayo. Ukongeza, i-HPMC inokunciphisa ukucaphuka eluswini kwaye ikhusele ulusu ekonakalisweni yimeko yangaphandle.
Umgubo wokuhlamba kunye neesepha eziqinileyo
Nangona i-HPMC ingasetyenziswanga kancinci kwizicoci eziqinileyo, isenokuthi idlale indima echasene ne-caking kunye nozinzo-lokuphucula indima ethile kwiifomyula ezithile zomgubo wokuhlamba. Inokuthintela umgubo ekubeni udibanise kwaye uqinisekise ukusasazeka kwayo xa isetyenziswa.
Izicoci ezikhethekileyo zomsebenzi
Kwezinye ii-detergents ezinemisebenzi ekhethekileyo, ezifana ne-antibacterial detergents, i-phosphate-free detergents, njl., i-HPMC, njengenxalenye yefomyula ye-compound, inokunyusa ixabiso elongezelelweyo lezi mveliso. Inokusebenza kunye nezinye izithako ezisebenzayo ukunyusa umphumo kunye nokuzinza kwemveliso.
4. Uphuhliso lwexesha elizayo lwe-HPMC kwicandelo lezokucoca
Njengoko iimfuno zabathengi zokhuseleko lokusingqongileyo kunye nempilo zikhula, ukuqulunqwa kwezicoci kukhula ngokuthe ngcembe kwindlela eluhlaza kunye nendalo. Njengemathiriyeli ehambelana nokusingqongileyo evela kwiselulosi yendalo, i-HPMC iyabola kwaye ayizukuba ngumthwalo kokusingqongileyo. Ke ngoko, kuphuhliso lwexesha elizayo lwezokucoca, i-HPMC kulindeleke ukuba yandise ngakumbi indawo yesicelo sayo.
Ngokuqhubela phambili kwetekhnoloji yokucoca, ubume bemolekyuli ye-HPMC inokuphuculwa ngakumbi kwaye iguqulwe ukuphuhlisa iimveliso ezisebenzayo ngakumbi. Ngokomzekelo, ngokuphucula ukuguquguquka kwayo kwiqondo lokushisa okanye i-pH, i-HPMC inokugcina ukusebenza kwayo okugqwesileyo phantsi kweemeko ezinzima kakhulu.
I-HPMC iye yaba yenye yezongezo ezibalulekileyo kwicandelo lezokucoca ngenxa yeempawu zayo ezibalaseleyo zomzimba kunye neekhemikhali ezifana nokujiya, ukuzinzisa, ukubunjwa kwefilimu, kunye nokunqunyanyiswa. Ayiphuculi kuphela amava okusetyenziswa kwezicoci, kodwa ikwanika iimveliso uzinzo olunamandla kunye nokusebenza. Kwixesha elizayo, kunye nokuqhubela phambili kwesayensi kunye nobuchwepheshe, amathuba okusetyenziswa kwe-HPMC kwi-detergents aya kuba banzi, kwaye iya kuzisa izisombululo ezintsha kwishishini.
