IHydroxypropyl Methyl Cellulose (HPMC)
1. Izinzile kwi-asidi kunye ne-alkali, kwaye isisombululo sayo samanzi sizinzile kakhulu kuluhlu lwe-pH = 2-12. I-soda ye-caustic kunye namanzi e-lime ayinayo impembelelo enkulu ekusebenzeni kwayo, kodwa i-alkali inokukhawulezisa izinga lokuchithwa kwayo kwaye yandise i-viscosity yayo.
2. I-HPMC yi-agent ephezulu yokugcina amanzi kwi-powder mortar system eyomileyo, enokunciphisa izinga lokuphuma kwegazi kunye ne-layer degree of mortar, ukuphucula ukuhambelana kodaka, ukuthintela ngokufanelekileyo ukubunjwa kweplastiki kwi-mortar, kunye nokunciphisa iplastiki. isalathisi sodaka.
3. I-electrolyte engeyona i-ionic kunye ne-non-polymeric, ezinzileyo kakhulu kwiisombululo ezinamanzi ezinamatye eetyuwa zetsimbi kunye ne-electrolytes ye-organic, kwaye inokongezwa kwizinto zokwakha ixesha elide ukuze kuqinisekiswe ukuqina kwayo kuphuculwe.
4. Ukusebenza kodaka kuye kwaphuculwa kakhulu. Umdaka ubonakala ngathi "unamafutha", anokuthi adibanise iindonga ezigcweleyo, agudise umphezulu, enze udaka kunye nesiseko se-bond bond, kunye nokwandisa ixesha lokusebenza.
ukugcinwa kwamanzi
Ukufezekisa ukugcinwa kwangaphakathi, okuhambelana nokuphucula amandla exesha elide
Vimba ukopha, thintela udaka ekuzinzeni nasekuncipheni
Ukuphucula ukuxhathisa kokuqhekeka kodaka.
jiya
Ukuchasa ulwahlulo, ukuphucula ukufana kodaka
Iphucula amandla ebhondi emanzi kwaye iphucula ukuxhathisa kwe-sag.
yopha umoya
Ukuphucula ukusebenza kodaka
Njengoko i-viscosity ye-cellulose iba phezulu kwaye ikhonkco le-molekyuli lide, umphumo wokungenisa umoya ubonakala ngakumbi.
Ukuhlehla
I-Synergizes kunye nokugcinwa kwamanzi ukwandisa ixesha elivulekileyo lodaka.
I-Hydroxypropyl starch ether (HPS)
1. Umxholo ophezulu we-hydroxypropyl kwi-starch ether unika inkqubo nge-hydrophilicity ezinzileyo, ukwenza amanzi akhululekile kumanzi adibeneyo kwaye adlale indima enhle ekugcineni amanzi.
2. Isitashi se-ethers esinomxholo ohlukeneyo we-hydroxypropyl siyahluka kwikhono labo lokuncedisa i-cellulose ekugcinweni kwamanzi phantsi kwedosi efanayo.
3. Ukutshintshwa kweqela le-hydroxypropyl kwandisa idigri yokwandisa emanzini kwaye kucinezele indawo yokuhamba kweengqungquthela, ngaloo ndlela kwandisa i-viscosity kunye nefuthe lokuqina.
Thixotropic lubricity
Ukusabalalisa ngokukhawuleza kwe-starch ether kwinkqubo yodaka kutshintsha i-rheology yodaka kwaye inika i-thixotropy. Xa kusetyenziswe amandla angaphandle, i-viscosity yodaka iya kuncipha, iqinisekisa ukusebenza kakuhle, ukumpompa, kunye nesipho Xa amandla angaphandle ehoxisiwe, i-viscosity iyanda, ukwenzela ukuba umdaka ube nokusebenza kakuhle kwe-anti-sagging kunye ne-anti-sag, kwaye kwi-putty powder, ineenzuzo zokuphucula ukukhanya kweoli ye-putty, ukukhazimula okukhazimlayo, njl.
Isiphumo sokugcina amanzi ancedisayo
Ngenxa yempembelelo yeqela le-hydroxypropyl kwinkqubo, i-starch ether ngokwayo ineempawu ze-hydrophilic. Xa idibaniswe ne-cellulose okanye ifakwe kwisixa esithile sodaka, inokunyusa ukugcinwa kwamanzi kwinqanaba elithile kwaye iphucule ixesha lokumisa phezulu.
I-Anti-sag kunye ne-anti-slip
Umphumo ogqwesileyo wokuchasana ne-sagging, isiphumo sokubumba
I-latex powder enokuchithwa kwakhona
1. Ukuphucula ukusebenza kodaka
Iinqununu ze-rubber ze-powder zihlakazekile kwinkqubo, zinika inkqubo nge-fluidity enhle, ukuphucula ukusebenza kunye nokusebenza kodaka.
2. Ukuphucula ukomelela kwebhondi kunye nokudityaniswa kodaka
Emva kokuba i-powder yerabha ihlakazekile kwifilimu, i-inorganic matter kunye ne-organic matter kwinkqubo yodaka idityaniswe kunye. Inokucinga ukuba isanti ye-samente kwi-mortar yi-skeleton, kwaye i-latex powder yenza i-ligament kuyo, eyandisa ukubambisana kunye namandla. yenza ulwakhiwo oluguquguqukayo.
3. Ukuphucula ukuxhathisa kwemozulu kunye nokumelana nokunyibilika kodaka
I-Latex powder yi-resin ye-thermoplastic ene-flexibility efanelekileyo, enokwenza ukuba udaka luhlangabezane nokubanda kwangaphandle kunye nokutshintsha kobushushu, kwaye kuthintela ngokufanelekileyo udaka ekuqhekekeni ngenxa yokutshintsha kweqondo lokushisa.
4. Ukuphucula amandla e-flexural yodaka
Iingenelo zepolymer kunye ne-samente paste ziyancedisana. Xa ukuqhekeka kuveliswa ngamandla angaphandle, i-polymer inokuwela iintambo kwaye ivimbele ukuqhekeka ekwandiseni, ukwenzela ukuba ukuphulwa kwe-fracture kunye nokukhubazeka kodaka kuphuculwe.
