Ukugcinwa kwamanzi: I-HPMC, njengento yokugcina amanzi, inokuthintela ukuvela kwamanzi amaninzi kunye nokulahlekelwa kwamanzi ngexesha lenkqubo yokunyanga. Le propati yokugcinwa kwamanzi iqinisekisa i-hydration eyaneleyo yesamente kwaye iphucula amandla kunye nokuqina kodaka. Kwiindawo eziphakamileyo zokushisa, ukugcinwa kwamanzi kwe-HPMC kubaluleke kakhulu ukukhusela udaka ukuba ulahlekelwe ngamanzi ngokukhawuleza, ngaloo ndlela uqinisekisa ukusebenza kodaka.
Ukusebenza: I-HPMC inempembelelo enkulu ekusebenzeni kodaka. Ngokuhambisa i-lubrication, inokunciphisa ukungqubuzana phakathi kwamaqhekeza, okwenza kube lula ukuyifaka. Oku kuphucuka kokusebenza kuqinisekisa inkqubo yokwakha esebenzayo.
Ukunciphisa i-shrinkage kunye nokuqhekeka: I-Srinkage kunye nokuqhekeka yimingeni eqhelekileyo kwizicelo zodaka, okubangela ukuba ukuqina kuchaphazeleke. I-HPMC yenza i-matrix eguquguqukayo kwi-mortar, ukunciphisa uxinzelelo lwangaphakathi kunye nokunciphisa ukwenzeka kwee-cracks ze-shrinkage, ngaloo ndlela iphucula ukuqina okupheleleyo kodaka.
Ukuphucula amandla e-flexural: I-HPMC ikwandisa amandla omdaka wodaka ngokuqinisa i-matrix kunye nokuphucula ukudibanisa phakathi kwamaqhekeza. Oku kuya kuphucula amandla okumelana noxinzelelo lwangaphandle kunye nokuqinisekisa ukuzinza kwesakhiwo.
Iimpawu ze-Thermal: Ukongezwa kwe-HPMC kunokuvelisa izinto ezilula kunye nokunciphisa ubunzima be-11.76%. Le porosity ephezulu inceda nge-thermal insulation kwaye inokunciphisa ukuhanjiswa kwezinto ukuya kuthi ga kwi-30% ngelixa igcina ubushushu obusisigxina malunga ne-49W xa iphantsi kobushushu obufanayo. Ukuxhatshazwa kokutshintshwa kobushushu ngephaneli kuyahluka kunye nenani le-HPMC elongeziweyo, kwaye inani eliphezulu lezongezo liphumela kwi-32.6% yokwanda kwe-thermal resistance xa kuthelekiswa nomxube wereferensi.
Ukungena komoya: I-HPMC inokunciphisa amandla omhlaba wesisombululo samanzi ngenxa yobukho bamaqela e-alkyl, ukwandisa umxholo werhasi ekusasazeni, kwaye ukuqina kwefilimu ye-bubble kuphezulu kunoko kwamaqamza acocekileyo, okwenza kube nzima ukukhupha. . Oku kunyanzeliswa komoya kunokunciphisa amandla okuguquguquka kunye nokunyanzeliswa kwemizekelo yodaka lwesamente, kodwa kuya kwandisa nokugcinwa kwamanzi kwidaka.
Isiphumo sobushushu kwi-gelation: Uphononongo lubonise ukuba iqondo lokudumba elilinganayo le-HPMC hydrogel liyehla ngokunyuka kobushushu. Ubushushu bunempembelelo ebalulekileyo ekuziphatheni ukudumba kwe-HPMC hydrogel, enokuthi ichaphazele iipropati zayo zodaka kumaqondo obushushu ahlukeneyo.
Impembelelo yobushushu kunye noxinzelelo lwepolymer kwisakhono sokumanzisa: Utshintsho kwiqondo lobushushu kunye noxinzelelo lwe-HPMC luchaphazela ukuxinana komphezulu oguqukayo kunye nokukwazi ukumanzisa kwesisombululo saso samanzi. Njengoko uxinaniso lwe-HPMC lusanda, ixabiso le-angle yoqhagamshelwano oluguquguqukayo lwesisombululo nalo landa, ngaloo ndlela lunciphisa ukuziphatha okusasazeka kwendawo yethebhulethi ye-Avicel.
I-HPMC inefuthe elibalulekileyo ekusebenzeni kodaka kumaqondo obushushu ahlukeneyo, kwaye inokuphucula ukugcinwa kwamanzi kudaka, iphucule ukusebenza kakuhle, iphucule ukumelana nokuqhekeka, iphucule amandla okubopha, iphucule ukuqina, inciphise ukushwabana nokuqhekeka, iphucule ukunganyangeki kwamanzi kunye nokunganyanzeki, iphucule umkhenkce. -nyibilikisa ukumelana, nokuphucula amandla bond tensile. Ezi mpawu zenza i-HPMC isongezo esibalulekileyo sokuphucula ukuqina kodaka.
