I-Hydroxypropyl Methyl Cellulose I-HPMC
1. Inokuqina kwe-asidi ne-alkali, futhi isixazululo sayo esinamanzi sizinze kakhulu ebangeni le-pH=2 ~ 12.I-Caustic soda namanzi e-lime ayinawo umthelela omningi ekusebenzeni kwawo, kodwa i-alkali ingasheshisa izinga lokuchithwa kwayo futhi ithuthukise kancane i-viscosity.
2. I-HPMCiyi-ejenti yokugcina amanzi esebenzayoudaka olomileuhlelo, olunganciphisa izinga lokufihla udaka kanye ne-stratification, luthuthukise ukuhlangana kodaka, luvimbele ngokuphumelelayo ukwakheka kwemifantu yepulasitiki yodaka, futhi kunciphise inkomba yokuqhekeka kwepulasitiki.
I-3, i-electrolyte engeyona i-ionic ne-non-polymeric, ezinzile kakhulu ezixazululweni ezinamanzi kasawoti wensimbi kanye nama-electrolyte e-organic, futhi ingangezwa ezintweni zokwakha isikhathi eside ukuze kuqinisekiswe ukuthi ukuqina kwayo kuyathuthukiswa.
I-4, ukusebenza kodaka kuye kwathuthukiswa kakhulu, udaka lubonakala "lunamafutha", lungenza udonga oluhlangene lugcwele, bushelelezi, ukuze udaka kanye nesibopho sesisekelo siqine, futhi singanweba isikhathi sokusebenza.
Ukugcinwa kwamanzi
Ukugcwaliseka kokwelapha kwangaphakathi kusiza ekwenzeni ngcono amandla esikhathi eside, ukuvimbela ukopha, ukuvinjelwa kokuhlala kodaka, ukuncipha kanye nokwenza ngcono ukumelana nodaka lokuqhekeka.
Ukuqina
Vimbela ukuhlukaniswa, thuthukisa ukufana kodaka, uthuthukise amandla ebhondi emanzi, futhi uthuthukise ukusebenza kokulwa nokulenga.
Ukungena emoyeni
Ukuthuthukisa ukusebenza kodaka.Ngokuphakama kwe-viscosity ye-cellulose, uma iketango lamangqamuzana lide, umphumela wokungena komoya ubonakala kakhulu.
I-coagulation ebambezelekile
Sebenzisana nokugcinwa kwamanzi ukuze unwebe isikhathi sokuvula udaka
I-Hydroxypropyl Isitashi ether
1. Okuqukethwe okuphezulu kwe-hydroxypropyl ku-starch ether kunikeza uhlelo i-hydrophilicity ezinzile, ukuguqula amanzi amahhala abe amanzi ahlanganisiwe, okudlala indima enhle yokugcina amanzi.
2. Ama-ether esitashi anokuqukethwe kwe-hydroxypropyl ahlukene anamakhono ahlukene okusiza i-cellulose ekugcineni amanzi ngesilinganiso esifanayo.
3. Ukufakwa esikhundleni kweqembu le-hydroxypropyl kwandisa izinga lokuvuvukala emanzini futhi kucindezele isikhala sokugeleza kwezinhlayiyana, ngaleyo ndlela kuzuzwe umphumela wokuqina kanye ne-viscosity ekhulayo.
Thixotropic lubricity
I-starch ether ihlakazeka ngokushesha ohlelweni lodaka, ishintsha i-rheology yodaka futhi inikeze i-thixotropy.Lapho kusetshenziswa amandla angaphandle, i-viscosity yodaka izoncishiswa, iqinisekise ukwakhiwa okuhle nokudonsa, futhi inikeze i-thixotropy.Inomuzwa obushelelezi.Lapho amandla angaphandle ehoxiswa, i-viscosity iyanda, okunikeza udaka ukumelana okuhle nokuncipha.Phakathi kwama-putty powders, inezinzuzo zokuthuthukisa ukugqama kwamafutha e-putty nokukhanya kokupholisha.
Umphumela wokugcina amanzi osizayo
I-starch ether ngokwayo inezici ze-hydrophilic ngenxa yendima yamaqembu e-hydroxypropyl ohlelweni.Uma ihlanganiswe ne-cellulose noma ingezwe ngenani elithile odakeni, ingakhuphula ukugcinwa kwamanzi ngokwezinga elithile futhi ithuthukise isikhathi sokumisa phezulu.
I-Anti-sag kanye ne-anti-slip
Umphumela omuhle kakhulu we-anti-sag kanye nomphumela wokubumba.
I-polymer powder ehlakazeka kabusha
1. Thuthukisa ukusebenza kodaka.I-powde ehlakazeka kabushar or I-RDPizinhlayiya zihlakazeka ohlelweni, okunikeza uhlelo uketshezi oluhle nokuthuthukisa ukusebenza nokusebenza kodaka.
2. Thuthukisa amandla okubopha odaka.Ngemva kokuba impushana yenjoloba isihlakazekile ibe yifilimu, i-inorganic and organic matter ohlelweni lodaka ingahlanganiswa ndawonye.Kungacatshangwa ukuthi usimende nesihlabathi odakeni ngamathambo, futhi i-latex powder yakha imigqa.Ukuhlangana kuyanda, amandla ayanda, futhi isakhiwo esiguquguqukayo siyakhiwa kancane kancane.
3. Thuthukisa ukumelana nesimo sezulu sodaka.I-latex powder engamelana ne-Freeze-thaw iyi-resin ye-thermoplastic ene-flexible eguquguqukayo, engenza udaka luphendule izinguquko zangaphandle emakhazeni nasekushiseni, ukuvimbela ngokuphumelelayo udaka ekuqhekekeni ngenxa yokushintsha kwezinga lokushisa.
4. Thuthukisa amandla aguquguqukayo odaka.I-polymer kanye nodaka lukasimende kwakha izinzuzo ezihambisanayo.Uma ukuqhekeka kubangelwa amandla angaphandle, i-polymer ingakwazi ukwelula imifantu futhi ivimbele ukunwetshwa kwemifantu, ngaleyo ndlela ithuthukise ukuqina kwe-fracture nokukhubazeka kodaka.
