IHydroxypropyl Methyl Cellulose (HPMC)
1. Iqinile ku-asidi ne-alkali, futhi isisombululo sayo esinamanzi sizinzile 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 ikhulise kancane i-viscosity yayo.
2. I-HPMC iyi-ejenti yokugcina amanzi esebenza kahle kakhulu yesistimu ye-powder mortar eyomile, enganciphisa izinga lokuphuma kwegazi kanye ne-layer degree of mortar, ithuthukise ukuhlangana kodaka, ivimbele ngokuphumelelayo ukwakheka kwemifantu yepulasitiki odakeni, futhi inciphise ipulasitiki. ukuqhekeka index of mortar.
3. I-electrolyte engeyona i-ionic ne-non-polymeric, ezinzile kakhulu ezixazululweni ezinamanzi aqukethe usawoti wensimbi kanye nama-electrolyte aphilayo, futhi ingafakwa ezintweni zokwakha isikhathi eside ukuze kuqinisekiswe ukuqina kwayo kuthuthukiswa.
4. Ukusebenza kodaka kwenziwe ngcono kakhulu. Udaka lubonakala "lunamafutha", olungenza amalunga odonga agcwale, abushelelezi ubuso, enze udaka kanye nesibopho sesendlalelo sesisekelo siqine, futhi andise isikhathi sokusebenza.
ukugcinwa kwamanzi
Ukuzuza ukunakekelwa kwangaphakathi, okuhambisana nokuthuthukiswa kwamandla esikhathi eside
Vimbela ukopha, vimbela udaka ekuzinzeni nasekuncipheni
Thuthukisa ukumelana nokuqhekeka kodaka.
jiya
Ukulwa nokuhlukaniswa, thuthukisa ukufana kodaka
Ithuthukisa amandla ebhondi emanzi futhi ithuthukise ukumelana ne-sag.
wopha umoya
Thuthukisa ukusebenza kodaka
Njengoba i-viscosity ye-cellulose iba phezulu kanye neketanga lamangqamuzana lide, umphumela wokungena komoya ubonakala kakhulu.
Ukuhlehlisa
Isebenzisana nokugcinwa kwamanzi ukuze kwelule isikhathi sokuvula sikadaka.
I-Hydroxypropyl starch ether (HPS)
1. Okuqukethwe okuphezulu kwe-hydroxypropyl ku-starch ether kunikeza uhlelo i-hydrophilicity ezinzile, okwenza amanzi amahhala abe amanzi ahlanganisiwe futhi adlale indima enhle ekugcineni amanzi.
2. Ama-ether esitashi anokuqukethwe okuhlukile kwe-hydroxypropyl ayahluka ekhonweni lawo lokusiza i-cellulose ekugcineni amanzi ngaphansi komthamo ofanayo.
3. Ukufakwa esikhundleni kweqembu le-hydroxypropyl kwandisa izinga lokunwetshwa emanzini futhi kucindezele isikhala sokugeleza kwezinhlayiya, ngaleyo ndlela kwandise i-viscosity nomphumela wokuqina.
Thixotropic lubricity
Ukuhlakazwa okusheshayo kwe-starch ether ohlelweni lodaka kushintsha i-rheology yodaka futhi kunikeze i-thixotropy. Lapho kusetshenziswa amandla angaphandle, i-viscosity ye-mortar izokwehla, iqinisekise ukusebenza kahle, ukudonsa, kanye ne-endowment Lapho amandla angaphandle ehoxiswa, i-viscosity iyanda, ukuze udaka lube nokusebenza okuhle kwe-anti-sagging kanye ne-anti-sag, futhi ku-putty powder, inezinzuzo zokuthuthukisa ukugqama kwamafutha e-putty, ukugqama kokupholisha, njll.
Umthelela wokugcinwa kwamanzi asizayo
Ngenxa yomphumela weqembu le-hydroxypropyl ohlelweni, i-starch ether ngokwayo inezici ze-hydrophilic. Uma ihlanganiswa ne-cellulose noma yengezwe esilinganisweni esithile sodaka, ingakhuphula ukugcinwa kwamanzi ngezinga elithile futhi ithuthukise isikhathi sokumisa phezulu.
I-Anti-sag kanye ne-anti-slip
Umphumela omuhle kakhulu we-anti-sagging, umphumela wokubumba
Impushana ye-latex ehlakazeka kabusha
1. Thuthukisa ukusebenza kodaka
Izinhlayiya zenjoloba zempuphu zihlakazeka ohlelweni, zinikeza isistimu nge-fluidity enhle, ukuthuthukisa ukusebenza nokusebenza kodaka.
2. Thuthukisa amandla esibopho nokuhlangana kodaka
Ngemva kokuba impushana yenjoloba isihlakazekile ibe yifilimu, i-inorganic matter kanye ne-organic matter ohlelweni lodaka kuyahlanganiswa. Kungase kucatshangelwe ukuthi isihlabathi se-samente odakeni yi-skeleton, futhi i-latex powder yakha i-ligament kuyo, okwandisa ukuhlangana namandla. yakha isakhiwo esivumelana nezimo.
3. Thuthukisa ukumelana nesimo sezulu kanye nokumelana nokuncibilika kodaka
I-Latex powder iyi-resin ye-thermoplastic ene-flexibility enhle, engenza udaka lubhekane nokubandayo kwangaphandle noshintsho lokushisa, futhi luvimbele ngokuphumelelayo udaka ekuqhekekeni ngenxa yezinguquko zokushisa.
4. Thuthukisa amandla aguquguqukayo odaka
Izinzuzo ze-polymer nokunamathisela usimende ziyahambisana. Uma imifantu ikhiqizwa ngamandla angaphandle, i-polymer ingakwazi ukuwela imifantu futhi ivimbele ukuqhekeka ekukhuleni, ukuze ukuqina kwe-fracture nokukhubazeka kodaka kuthuthukiswe.
