IHydroxypropylmethylcellulose (HPMC) yi-semi-synthetic polymer esetyenziswa kakhulu kwiinkalo ezahlukeneyo.Umgubo omhlophe okanye omhlophe, onyibilika ngokulula emanzini, kunye nokuzinza okuhle kwe-thermal.Ngenxa yeempawu zayo ezibalaseleyo, iye yaba sisithako esidumileyo kwizicelo ezininzi ezahlukeneyo.Kweli phepha, siphonononga izizathu zokusetyenziswa ngokubanzi kwe-HPMC.
1. Ukhuseleko kunye nokusiNgqongileyo
Esinye sezizathu ezingundoqo HPMC isetyenziswa ngokubanzi kuba ikhuselekile kwaye friendly kokusingqongileyo.I-HPMC ithathwe kwi-cellulose, imathiriyeli eninzi ngokwendalo..Ngokungafaniyo neepholima zokwenziwa, i-HPMC iyabola kwaye ayikhuphi izinto eziyingozi kwindalo esingqongileyo.Ukongezelela, ayinayo ityhefu kwaye ayifaki nayiphi na ingozi yempilo ebantwini okanye kwizilwanyana.
2. Ukuguquguquka
Esinye isizathu sokusetyenziswa ngokubanzi kwe-HPMC kukuguquguquka kwayo..Ngenxa yeempawu zayo ezizodwa, i-HPMC ingasetyenziswa kuluhlu olubanzi lwezicelo.Ngokomzekelo, isetyenziswe kwishishini lokutya njenge-thickener, i-binder, i-emulsifier, i-stabilizer, njl. ukuphucula ukugcinwa kwamanzi kunye nokusebenza kwesamente nodaka.Ukongezelela, isetyenziswe njengento yokugqoka kwimizi-mveliso ye-textile kunye nephepha.
3. Ukusebenza okugqwesileyo
Iimpawu ezigqwesileyo ze-HPMC zenza ukuba ibe yinto efanelekileyo kwizicelo ezininzi.Ngokomzekelo, ine-solubility egqwesileyo yamanzi, eyenza i-soluble ngokukhawuleza kwizisombululo ezinamanzi.Kwakhona ine-dispersibility enhle, iqinisekisa ukusasazeka kwezinto kwimveliso yokugqibela..Ukongezelela, iimpawu zayo ze-rheological ziyakwazi ukulungiswa ngokutshintshana kweqondo lokuthatha indawo kunye nobunzima be-molecular, okwenza kube kulungele uluhlu olubanzi lwezicelo.
4. Ukonga imali
I-HPMC ikwasetyenziswa ngokubanzi kuba yenye yeendleko ezisebenzayo kwezinye iipholima.Ixabiso eliphantsi kunezinye iipholima zokwenziwa, nto leyo eyenza ukuba ibe lukhetho olunomtsalane kubavelisi.Ngaphezu koko, iipropathi zayo ezibalaseleyo zokusebenza kunye nokuguquguquka kwezinto kuyenza ibe sisithako esifanelekileyo kwizicelo ezininzi ezahlukeneyo.
5. Imvume yoLawulo
Okokugqibela, i-HPMC isetyenziswa ngokubanzi kuba ivunyiwe zii-arhente ezilawulayo kwihlabathi liphela.Ithathwa njengekhuselekile ekutyeni, kwiziyobisi nakwizithambiso.Ngaphezu koko, isetyenziswe kula mashishini iminyaka, ngoko uphando oluninzi lwenziwe kukhuseleko kunye nokusebenza kwayo.
Isishwankathelo, i-hydroxypropyl methylcellulose iyisithako esisebenzayo, esineendleko kunye nesikhuselekileyo esisetyenziswa ngokubanzi kwiindidi ezahlukeneyo zamashishini.Ukhuseleko lwayo kunye nobuhlobo bendalo, kunye nokuvunyelwa okusemthethweni, kuye kwanyusa ngakumbi ukuthandwa kwayo.
