Uhlobo lokuzilungiselela lusetshenziswa kabanzi embonini yezokwakha ukuze kufakwe nezindawo ezibushelelezi ngaphambi kokufaka isembozo saphansi njengamathayili, amakhaphethi noma izingodo. Lokhu kudonswa kwemali kunikeza izinzuzo eziningana ngaphezulu kwamakhompiyutha wendabuko wokulinganisa, kufaka phakathi ukusetshenziswa kalula, ukomisa okusheshayo nokuqedwa komhlaba okuthuthukile. I-Hydroxypropyl Methylcellulose (HPMC) iyisithako esibalulekile ekuziphatheni okuzimele ngenxa yekhono layo lokuguqula i-RHEOLOGY, thuthukise ukukhiqizwa kanye nokukhulisa ukunamathela.
Izithako eziphambili
1. I-Hydroxypropylmethylcelcelcelcellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellellose (HPMC)
I-HPMC iyisisulu se-cellulose esetshenziswa kakhulu ezintweni zokwakha njengomuntu omkhulu, i-Binder kanye ne-ejenti yokugcina amanzi. Ku-maleveling woman, i-HPMC isebenza njengokushintsha kwe-Rheology, ukuthuthukisa ukugeleza kwezakhiwo nokuvimbela ukwahlukaniswa. Ukukhethwa kwebanga le-HPMC kuzothinta i-viscosity kanye nezakhiwo zodaka.
2. Usimende
Usimende uyisigaxa esikhulu ku-dat-selveling udaka. I-Corther Portand Cument (OPC) ivame ukusetshenziswa ngenxa yokutholakala kwayo kanye nokuhambisana nezinye izithako. Ukusatshalaliswa kwekhwalithi nosayizi wezinhlayiyana kwethonya kuthonya amandla nezici zodaka.
3. Ukuhlanganiswa
Ama-aggregates amahle anjengesihlabathi angezwe kwingxube yodaka ukuze athuthukise izakhiwo zawo zemishini, kufaka phakathi amandla nokuqina. Ukusatshalaliswa kosayizi wezinhlayiyana kwe-adgregate kuthinta uketshezi kanye nokuqedwa kwendawo yodaka.
4. Izengezo
Izithasiselo ezahlukahlukene zingafakwa ekwakhiweni kodaka ukuthuthukisa izakhiwo ezithile ezifana nesikhathi, ukunamathela kanye nokugcinwa kwamanzi. Lezi izengezo zingafaka ama-superplastifizer, ama-agents angenisa umoya kanye nama-coabulants.
Amanothi weresiphi
1. Ukulawulwa kwe-Viscosity
Ukuthola ukubonakala okuphansi kubaluleke kakhulu kuma-maser-welveling wodonga ukuze uqinisekise ukuthi kalula isicelo nokugeleza okufanele engxenyeni engezansi. Ukukhethwa kwebanga le-HPMC, umthamo kanye nokusatshalaliswa kosayizi wezinhlayiyana kudlala indima ebalulekile ekulawuleni i-visconging. Ngaphezu kwalokho, ukusetshenziswa kwama-superplastizer kungaphinde kunciphise ukubonwa ngaphandle kokuthinta ezinye izakhiwo.
2. Setha isikhathi
Isikhathi esilinganiselayo sibalulekile ukuvumela isikhathi esanele sohlelo lokusebenza nokulinganisa ngenkathi siqinisekisa ukwelashwa okufika ngesikhathi kanye nokuthuthuka kwamandla. Ukusetha isikhathi kungashintshwa ngokushintsha isilinganiso sikasimende emanzini, ukungeza ama-accelerator noma ama-retaarders, nokulawula okushisa okukhona.
3. Izici zokugeleza
Ukugeleza kodaka oluzimele kubalulekile ekufezekiseni ukumbozwa komhlaba kanye nokuqedwa okubushelelezi. Ukuqalwa kwama-aggregate aggregate, isilinganiso esilungiselelwe amandla esilinganiselwe samanzi kanye nama-Rheology modifiers anjenge-HPMC asiza ukufeza izici zokugeleza ezifunwayo. Ukunakekelwa kufanele kuthathwe ukugwema ukopha ngokweqile noma ukwahlukaniswa okwedlulele ngesikhathi sokusetshenziswa.
4. Ukunamathela namandla ehlanganisa
Ukunamathelisa okuhle ku-substrate kuyadingeka ukuvikela ukunxusa futhi kuqinisekiswe ukuqina kwesikhathi eside. Abagqugquzeli abanama-adhesion, njengezinhlobo ezithile ze-HPMC, zingathuthukisa isibopho phakathi kodaka kanye nendawo engezansi. Ukulungiselela okungaphezulu komhlaba, kufaka phakathi ukuhlanza nokuqala, kungathuthukisa ukunamathela.
Inqubo Yokukhiqiza
Ukulungiswa kwento ephansi-vissusite HPMPC yokuzibonakalisa kuzilolonga kuhilela izinyathelo ezimbalwa njengokuvusa, ukuxuba, nokwakha. Nakhu ukubuka konke okujwayelekile kwenqubo yokukhiqiza:
1. Izithako
Linganisa futhi ulinganise inani elidingekayo likasimende, okuhlanganisiwe, i-HPMC nezinye izengezo ngokuya ngeresiphi enqunyelwe ngaphambili.
Qinisekisa izithako ezinembile zokugcina ukungaguquguquki kodaka nokusebenza.
2. Hlanganisa
Hlanganisa izithako ezomile (usimende, ohlanganisiwe) esitsheni esidilikayo esifanele.
Kancane kancane engeza amanzi ngenkathi uxuba ukuze uzuze ukuvumelana okufunwayo.
Yethula i-puder ye-HPMC kwingxube eqinisekisa ukuhlakazeka okufanele kanye ne-hydration.
Hlanganisa kahle kuze kube yilapho unamathisela lodaka olunama-homogeneous of viscosity aphansi atholakala.
Lungisa le ngxube njengoba kudingeka ukuze uhlangabezane nezidingo ezithile zokugeleza nokusetha isikhathi.
3. Faka isicelo
Lungiselela i-substrate ngokuhlanza, ukuhlela, kanye nokulinganisa njengoba kudingeka.
Thela udaka oluzimele oluya endaweni engezansi.
Sebenzisa ithuluzi lesicelo noma iphampu ye-mehendi ukusabalalisa udaka ngokulinganayo endaweni yonke.
Vumela udaka ukuze azinze futhi asuse umoya obhajwe ngokudlidliza noma ukushubisa.
Gada inqubo yokwelapha futhi uvikele udaka olusanda kufakwa ku-wortar kusuka ekulahlekelweni komswakama ngokweqile noma ukulimala kwemishini.
Ukulungiselela ukubonwa okuphansi kwe-HPMPC yokuzibonakalisa ukuzenzela kudinga ukukhethwa ngokucophelela kwezithako, ukucatshangelwa kokwakheka nezinqubo eziqondile zokukhiqiza. Ngokulawula ukubonwa, ukusetha isikhathi, izici zokugeleza kanye nokunamathelisa, abakhiqizi bangakhiqiza udaka olwenzelwe izidingo zesicelo esithile. Amasu Ofanele Wokwakhiwa Nezinqubo Zokulahla zibalulekile ekutholeni ukuqeda okuphezulu, okuqinile okuqinile okulungele amaphrojekthi wokwakha ahlukahlukene.
