Ukuphucula ukugcinwa kwamanzi: I-HPMC inokuphucula kakhulu ukugcinwa kwamanzi kwidaka. Idosi esezantsi ye-HPMC inokuphucula ngokubonakalayo ugcino lwamanzi lodaka. Ngokomzekelo, xa i-dosage yi-0.02%, izinga lokugcinwa kwamanzi linyuka ukusuka kwi-83% ukuya kwi-88%; xa idosi yi-0.2%, izinga lokugcinwa kwamanzi lifikelela kwi-97%. Ukusebenza kakuhle kokugcinwa kwamanzi kuqinisekisa i-hydration eyaneleyo yesamente kwaye iphucula amandla kunye nokuqina kodaka.
Ukuphuculwa kokusebenza: I-HPMC inokwenza udaka lubonise ukuguquguquka okungcono ngaphantsi kwamandla aphantsi okucheba, okwenza kube lula ukuyifaka kunye nenqanaba; ngelixa iphantsi kwamandla aphezulu okucheba, udaka lubonisa i-viscosity ephezulu, ukuthintela ukugoba kunye nokuhamba. . Le thixotropy ekhethekileyo yenza udaka lube lula ngexesha lokwakha, ukunciphisa ubunzima bokwakha kunye nokuqina kwabasebenzi.
Ukuphucula ukuxhathisa kokuqhekeka: Ngokwandisa imodyuli e-elastic kunye nokuqina kodaka, i-HPMC inokunciphisa ngokufanelekileyo ukwenzeka kweentanda, iphucule ukuxhathisa kokuqhekeka kodaka, kwaye yandise ubomi bayo benkonzo.
Ukunyuka kwamandla okuguquguqukayo: I-HPMC ikwandisa amandla omdaka wodaka ngokuqinisa i-matrix kunye nokuphucula ukudibanisa phakathi kweengqungquthela. Oku kuya kwandisa ukuchasana noxinzelelo lwangaphandle kunye nokuqinisekisa ukuzinza kwesakhiwo.
Amandla ebhondi aphuculweyo: I-HPMC yenza ifilimu encinci ejikeleze amaqhekeza, iphucula intsebenziswano phakathi kodaka kunye ne-substrate. Oku kubambelela okuqinisiweyo kuqinisekisa ibhondi eyomeleleyo, ukunciphisa umngcipheko wokulahla okanye ukusilela.
Ukuphuculwa kokuqina: Ukongezwa kwe-HPMC kunokuvelisa izinto ezilula, kunye nokunciphisa ubunzima be-11.76%. Olu hlobo luphezulu lwe-void ratio lunceda ngokugqunywa kwe-thermal, ukunciphisa umbane wezinto eziphathekayo ukuya kuthi ga kwi-30% ngelixa ugcina ubushushu obungatshintshiyo obumalunga ne-49W xa uphantsi kobushushu obufanayo. Ukuchasana nokuhanjiswa kobushushu ngephaneli kwahluka kunye nenani le-HPMC eyongeziweyo, kunye nokubandakanywa okuphezulu kwe-additive kubangela ukunyuka kwe-32.6% kwi-thermal resistance xa kuthelekiswa nomxube wereferensi.
Ukunciphisa i-Shrinkage kunye ne-Cracking: I-Srinkage kunye nokuqhekeka yimingeni eqhelekileyo kwizicelo zodaka, okubangelwa ukuqina kokunciphisa. I-HPMC yenza i-matrix eguquguqukayo ngaphakathi kodaka, ukunciphisa uxinzelelo lwangaphakathi kunye nokunciphisa ukwenzeka kokuqhekeka kwe-shrinkage.
Ukuphuculwa kokuchasana kwamanzi kunye nokungathinteli: Kwi-drywall kunye ne-caulk, i-HPMC iphucula ukuxhathisa kwamanzi kunye nokungaguquki, igcina uzinzo kwiindawo ezinomswakama kunye nokwandisa ubomi bezinto eziphathekayo.
Ukuphucula ukuxhathisa kokunyibilika komkhenkce: Ngenxa yokugcinwa kwamanzi okugqwesileyo kunye nokumelana nokuqhekeka, i-HPMC inokugcina ukusebenza okuzinzileyo kwiindawo ezingqongileyo ezigqithisileyo, iqinisekisa umgangatho wokwakha kunye nokuqina kodaka.
Phucula ukomelela kokuqina kokuqina: I-HPMC inokonyusa kakhulu amandla okubopha ukucheba kodaka. Ukongeza i-0.2% ye-HPMC inokunyusa amandla okudibanisa udaka ukusuka kwi-0.72MPa ukuya kwi-1.16MPa.
I-HPMC inefuthe elibonakalayo ekuphuculeni ukuqina kodaka. Inokuphucula ukugcinwa kwamanzi odaka, ukuphucula ukusebenza, ukuphucula ukuchasana nokuqhekeka, ukwandisa amandla okubambisana, ukuphucula ukuqina, ukunciphisa ukucutheka kunye nokuqhekeka, kunye nokuphucula ukuxhathisa kwamanzi kunye nokunganyanzeki. iipropathi, ziphucula ukuxhathisa ukunyibilika komkhenkce kunye nokuphucula amandla okuqina okubopha. Ezi zakhiwo zenza i-HPMC ibe yinto ebalulekileyo yokuphucula ukuqina kodaka.
