ukwethula:
Ama-cellulose ether asetshenziswa kabanzi embonini yokwakha ngenxa yezakhiwo zawo ezinhle zokugcina amanzi, ukuqina kanye nokubopha. Athuthukisa ukugeleza kanye nokucutshungulwa kwezinto ezisekelwe kusimende futhi athuthukise izakhiwo zemishini zomkhiqizo wokugcina. Ama-putties avame ukusetshenziswa embonini yokwakha ukugcwalisa imifantu, imigodi kanye nokunye ukungapheleli ezindongeni nasemaphahleni. Ukusetshenziswa kwama-cellulose ethers kuma-putty powder kungathuthukisa ukusebenza kahle, isikhathi sokusetha kanye nekhwalithi iyonke yomkhiqizo. Lesi sihloko sizoxoxa ngomphumela wokuqina okuhlukene kwama-cellulose ethers ku-putty powder.
Izinhlobo ze-cellulose ethers:
Kunezinhlobo ezahlukene zama-ether e-cellulose okuhlanganisa i-methylcellulose (MC), i-hydroxypropylmethylcellulose (HPMC), i-ethylcellulose (EC) kanye ne-carboxymethylcellulose (CMC). I-HPMC iyi-ether e-cellulose ethandwayo embonini yokwakha ngenxa yezakhiwo zayo ezinhle zokugcina amanzi, ukuqina kanye nokunamathela. I-HPMC iza ngezindlela ezahlukene zokukhanya, kusukela phansi kuya phezulu.
Umphumela we-cellulose ether ku-putty powder:
Impuphu ye-putty isetshenziselwa ukugcwalisa imifantu, imigodi kanye nokunye ukungapheleli ezindongeni nasemaphahleni. Ukusetshenziswa kwama-cellulose ethers kuma-putty powder kungathuthukisa ukusebenza kahle kanye nesikhathi sokusetha umkhiqizo. I-cellulose ether ingathuthukisa nokusebenza kahle kanye nokunamathela kwempuphu ye-putty. Okulandelayo umphumela wokuqina okuhlukene kwama-cellulose ethers kumpuphu ye-putty:
1. I-HPMC ephansi ene-viscosity:
I-HPMC ethambile ingathuthukisa ukugeleza nokusebenza kahle kwempuphu ye-putty. Iphinde ithuthukise isikhathi sokusetha umkhiqizo. I-HPMC ene-viscosity ephansi inezinga lokushisa eliphansi le-gelation, elingavimbela impuphu ye-putty ukuthi iqine ngokushesha kakhulu. Ingathuthukisa nokunamathelana komkhiqizo. I-HPMC ethambile ifaneleka kumpuphu ye-putty edinga ukusebenza kahle kanye nokushelela.
2. I-HPMC ethambile nethambile:
I-HPMC enobukhulu obuphakathi ingathuthukisa izakhiwo ze-thixotropic ze-putty powder. Ingathuthukisa futhi ukugcinwa kwamanzi nokusebenza kokubopha komkhiqizo. I-HPMC enobukhulu obuphakathi ingathuthukisa izakhiwo zemishini zomkhiqizo, njengokuqina nokuqina. Ifaneleka ku-putty powder edinga ukugcinwa kwamanzi okuhle kanye nokuhlangana.
3. I-HPMC ebonakala kakhulu:
I-HPMC enobukhulu obuphezulu ingathuthukisa ukusebenza kokuqina kanye nokungaboli kwempuphu ye-putty. Ingathuthukisa futhi ukugcinwa kwamanzi kanye nokusebenza kokubopha komkhiqizo. I-HPMC enobukhulu obuphezulu ingathuthukisa izakhiwo zemishini zomkhiqizo, njengokuqina nokuqina. Ifaneleka kumpuphu ye-putty edinga ukuqina okuphezulu kanye nokusebenza okulwa nokuboli.
Ekuphetheni:
Ama-cellulose ether asetshenziswa kabanzi embonini yokwakha ngenxa yezakhiwo zawo ezinhle zokugcina amanzi, ukuqina kanye nokubopha. I-HPMC isibe yi-cellulose ether ethandwayo embonini yokwakha ngenxa yezakhiwo zayo ezinhle kakhulu. I-HPMC iza ngezindlela ezahlukene zokuqina, kusukela phansi kuya phezulu. Ukusetshenziswa kwama-cellulose ether ane-viscosities ezahlukene kungathuthukisa ukusebenza, isikhathi sokusetha, ukusebenza kwe-thixotropic, ukugcinwa kwamanzi, ukusebenza kokubopha kanye nezakhiwo zemishini ze-putty powder. Ukusetshenziswa kwama-cellulose ether kungathuthukisa ikhwalithi kanye nokusebenza kwama-putty powder, okwenza afaneleke ukusetshenziswa okuhlukahlukene embonini yokwakha.
