Inokuba njani i-HPMC ibe sisityebi sodaka lwesamente

IHydroxypropyl methylcellulose(HPMC) ingasetyenziswa njengesamente slurry thickener ngenxa amandla ayo ukuguqula iimpawu rheological ludaka. Nantsi indlela esebenza ngayo i-HPMC njengesityebi kwi-slurries yesamente:

1. Ukugcinwa kwamanzi: I-HPMC ineempawu ezibalaseleyo zokugcina amanzi. Xa ifakwe kwi-sement slurry, inokufunxa kwaye igcine amanzi, ukuthintela ukulahleka kwamanzi ngaphambi kwexesha ngexesha lokuxuba, ukupompa, kunye nokubeka. Oku kunceda ukugcina ukuhambelana okufunwayo kwe-slurry kwaye kuthintele ukuba kungabi kakhulu okanye kome.
2. Ulawulo lwe-Viscosity: I-HPMC isebenza njenge-modifier ye-viscosity kwi-slurries yesamente. Ngokwandisa i-viscosity ye-slurry, iphucula ukuhamba kwayo kwaye inqande i-sedimentation ye-particle eqinile. Oku kubaluleke kakhulu kwizicelo ezithe nkqo okanye ezithe tye apho ukugcina ukufana kunye nokuthintela ulwahlulo kubalulekile.
3. Ukuziphatha kwe Thixotropic: I-HPMC inika ukuziphatha kwethixotropic kwi-slurries yesamente. Oku kuthetha ukuba i-slurry iba yi-viscous encinci phantsi koxinzelelo lwe-shear (njengexesha lokuxuba okanye ukumpompa) kodwa ibuyela kwi-viscosity yayo yasekuqaleni xa uxinzelelo lususiwe. Ukuziphatha kwe Thixotropic kuphucula ukusebenza kwe-slurry ngexesha lesicelo ngelixa unikezela uzinzo xa uphumle.
4. Ukomelezwa kokuSebenza: Ukongezwa kwe-HPMC kuphucula ukusebenza kwee-slurries zesamente, okwenza kube lula ukuxuba, ukumpompa, kunye nendawo. Iyanciphisa umngcipheko wokwahlula kunye nokuphuma kwegazi, okuvumela ukuhlanganiswa okungcono kunye nokudibanisa kwezinto ze-cementitious.
5. Ixesha lokumisela eliLawulwayo: I-HPMC inokuphembelela ixesha lokumisela i-slurries yesamente. Ngokulungelelanisa ugxininiso kunye nohlobo lwe-HPMC olusetyenzisiweyo, kunokwenzeka ukulawula umlinganiselo we-hydration kunye nokusekwa kwesamente, ukuqinisekisa ukuba ifezekisa iipropati zamandla ezifunwayo ngaphakathi kwexesha elichaziweyo.
6. Ukuhambelana kunye nezongezo: I-HPMC iyahambelana neentlobo ezahlukeneyo zokudibanisa ezisetyenziswa ngokuqhelekileyo kwimixube yesamente, ezifana ne-accelerators, i-retarders, kunye ne-fluid loss additives. Oku kuvumela ukulungiswa kwe-slurries yesamente ukuhlangabezana neemfuno ezithile zokusebenza kwizicelo ezahlukeneyo kunye neemeko zokusingqongileyo.
7. Iingqwalaselo zokusiNgqongileyo: I-HPMC ihambelana nokusingqongileyo kwaye ayinayo ityhefu, iyenza ibe lolona khetho lukhethwayo lokusetyenziswa kwi-slurries yesamente, ngakumbi kwizicelo apho imimiselo yokusingqongileyo ingqongqo.

I-HPMC isebenza njenge-thickener esebenzayo kunye ne-rheology modifier kwi-slurries yesamente, inikezela ukuphucula ukusebenza, ukuzinza, kunye nokusebenza kwizicelo ezahlukeneyo zokwakha.
