I-HPMC (Hydroxypropyl Methylcellulose)sisilulo seselulosi esinyibilikayo esinamanzi esisetyenziswa kakhulu kushishino lolwakhiwo, ngakumbi kudaka, iingubo kunye nokuncamathelisa. Indima yayo kumatshini wokutshiza udaka ibaluleke kakhulu, njengoko inokuphucula ukusebenza kodaka, yandise ukunamathela, iphucule ubumanzi kwaye yandise ixesha lokuvula.
1. Ukuphucula ukusebenza kodaka kunye nokwakhiwa kodaka
Omnye weyona misebenzi ibalulekileyo ye-HPMC kukuphucula ngokubonakalayo ubumanzi bodaka. Ekubeni i-HPMC ine-solubility efanelekileyo yamanzi, inokwenza isisombululo se-colloidal kwi-mortar, ikhulise ukuhambelana kodaka, kwaye iyenze ibe yinto efanayo kwaye igudileyo ngexesha lokwakha. Oku kubalulekile kwinkqubo yokutshiza ngoomatshini, efuna ulwelo oluthile lodaka ukuze lutshizwe eludongeni ngoxinzelelo oluphezulu kwisixhobo sokutshiza. Ukuba ukumanzi kodaka akwanelanga, kuya kubangela ubunzima bokutshiza, ukugquma ngokungalingani kokutshiza, kunye nokuvala umlomo wombhobho, oko kuchaphazela ukusebenza kakuhle kunye nomgangatho.
2. Ukuphucula ukunamathela kodaka
I-HPMC ineempawu ezintle zokudibanisa kwaye inokuphucula ukunamathela phakathi kodaka kunye nomgangatho wesiseko. Kwi-mechanical spray mortar, ukunamathela okulungileyo kubaluleke kakhulu, ngakumbi xa i-coating ifakwe kwii-facades okanye ezinye iintlobo ze-substrates.AnxinCel®HPMCinokuphucula ngokufanelekileyo ukunamathela kodaka kwisiseko sesiseko kunye nokunciphisa iingxaki zokulahla ezibangelwa yimeko yendalo (ezifana nokutshintsha kweqondo lokushisa kunye nomswakama). Kwangaxeshanye, i-HPMC inokuphucula ukuhambelana phakathi kodaka kunye nezinye izinto ukunqanda ukuxobuka kwe-interlayer okubangelwa iyantlukwano ehambelanayo.
3. Yandisa iiyure zokuvula kwaye ugcine ukusebenza kolwakhiwo
Kulwakhiwo lokutshiza ngoomatshini, ukwandiswa kwexesha lokuvulwa kodaka kubalulekile kumgangatho wokwakha. Ixesha lokuvula libhekisela kwixesha lexesha elisusela xa udaka lusetyenziswa phezu komhlaba de lome, kwaye ngokuqhelekileyo lufuna ukuba umsebenzi wokwakha akwazi ukwenza uhlengahlengiso, ukucutha kunye nohlengahlengiso ngeli xesha ngaphandle kokuchaphazela ukusebenza kodaka. I-HPMC inokwandisa kakhulu ixesha lokuvula ngokunyusa i-viscosity yodaka kunye nokunciphisa izinga lokunyuka kwamanzi. Oku kuvumela isitshizi ukuba sisebenze ixesha elide kwaye sinqanda ukuqhekeka komphezulu okanye ukutshiza okungalinganiyo okubangelwa kukomisa ngokukhawuleza.
4. Thintela i-delamination kunye nemvula
Kumatshini wokutshiza udaka, ngenxa yokuthuthwa kwexesha elide kunye nokugcinwa, i-particle precipitation ingenzeka kwi-mortar, ibangele i-delamination yodaka. I-HPMC ineempawu eziqinileyo zokunqunyanyiswa, ezinokuthintela ngokufanelekileyo amasuntswana amahle okanye amanye amacandelo odaka ekuzinzeni nasekugcineni ukufana kodaka. Olu phawu lubaluleke kakhulu ukuqinisekisa isiphumo sokutshiza kunye nomgangatho wodaka. Ngokukodwa kulwakhiwo olukhulu, ukugcina ukuhambelana kunye nokuzinza kodaka ngundoqo wokuqinisekisa umgangatho wokwakha.
5. Ukwandisa ukugcinwa kwamanzi kwidaka
Njengekhompawundi yepolymer enyibilikayo emanzini, i-HPMC inokugcinwa kwamanzi okuqinileyo. Yenza ifilimu ebhityileyo eludaka, ngaloo ndlela inciphisa ukufuma komswakama. Le propati ibaluleke kakhulu ukugcina udaka olumanzi kunye nokunciphisa ukwenzeka kweentanda. Ngokukodwa kwiindawo ezinobushushu obuphezulu, ubumanzi obuphantsi, udaka lunokomisa ngokukhawuleza kunye nokuqhekeka. I-HPMC inokunciphisa ngokusebenzayo ukwenzeka kwale meko ngokunyusa ugcino lwamanzi odaka kunye nokuqinisekisa ukuba udaka lunyangekile kwaye lunyangekile ngexesha elifanelekileyo.
6. Ukuphucula ukuxhathisa kokuqhekeka kunye nokuqina kodaka
Kuba i-HPMC inokuphucula ugcino lwamanzi kunye neepropathi zokudityaniswa kodaka, isenokwandisa ukumelana nokuqhekeka kunye nokuqina kodaka. Ngexesha lenkqubo yokutshiza ngoomatshini, ukufana kunye nokuzinza komgangatho wodaka kubalulekile ekuxhathiseni ukuqhekeka kwexesha elide. Ngokuphucula ukudibanisa kunye nokunamathela kwendawo yodaka, i-AnxinCel®HPMC iyanciphisa ngokufanelekileyo umngcipheko wokuqhekeka okubangelwa utshintsho lweqondo lokushisa, ukulungiswa kwesakhiwo okanye ezinye izinto zangaphandle, kunye nokwandisa ubomi benkonzo yomdaka.
7. Ukuphucula ukulungelwa kunye nokuzinza kwemisebenzi yokutshiza
Xa usebenzisa izixhobo zokutshiza ngoomatshini bokwakha, i-fluidity, i-viscosity kunye nokuzinza kodaka kubalulekile ekusebenzeni okuqhelekileyo kwesixhobo. I-HPMC inciphisa ukonakaliswa kwezixhobo zokutshiza kunye neemfuno zogcino ngokuphucula ulwelo kunye nokuzinza kodaka. Kwakhona kunokunciphisa ingxaki yokufakwa kodaka okanye ukuvala izixhobo, ukuqinisekisa ukuba izixhobo zihlala zigcina ukusebenza okuzinzile ngexesha leenkqubo zokwakha ixesha elide.
8. Ukwandisa ukuxhathisa kungcoliseko lodaka
HPMCineempawu ezichasene nongcoliseko. Inokuthintela ukunamathela kwezinto ezinobungozi okanye ukungcola kumdaka kunye nokugcina ukucoceka kodaka. Ngokukodwa kwezinye iindawo ezikhethekileyo, udaka luchaphazeleka lula kungcoliseko lwangaphandle. Ukongezwa kwe-HPMC kunokuthintela ngokufanelekileyo ukunamathela kwezi zinto zingcolisa, ngaloo ndlela ziqinisekisa umgangatho wokwakha kunye nenkangeleko.
Indima ye-HPMC kudaka lomatshini wokutshiza lunamacala amaninzi. Ayinakuphucula kuphela ukusebenza kwe-fluidity kunye nokwakhiwa kodaka, kodwa nokuphucula ukunamathela, ukwandisa ixesha lokuvula, ukuphucula ukugcinwa kwamanzi, ukuphucula ukunyanzeliswa kokuqhekeka kunye nokuphucula amandla okuchasana nokungcola, njl. Ke ngoko, i-HPMC isetyenziswa kakhulu kulwakhiwo lwangoku lwezakhiwo, ngakumbi kudaka olutshizwa ngoomatshini, apho ludlala indima engenakuphinda ithathelwe indawo nebalulekileyo.
