I-HEMC isetshenziswe ku-Skim Coat

I-cellulose etherI-HEMC yi-Hydroxyethyl Methyl cellulose esetshenziswayonjenge-ejenti ejiyayo yokugcina amanzi ekusetshenzisweni kweI-Skim Coat, ngenxa ye-thixotropy ye-cellulose ngokwayo, ukungezwa kweI-HEMCi-cellulose ether ku-Skim Coat powder nakho kwaholela kuthixotropy we-Skim Coat ngamanzi. Le thixotropy ibangelwa ukucekelwa phansi kwesakhiwo esiboshwe ngokukhululekile sezingxenye ze-Skim Coat powder. Lesi sakhiwo sakhiwe ekuphumuleni futhi sihlakazeka ngaphansi kokucindezeleka. Okusho ukuthi, i-viscosity iyancipha ngesikhathi sokuyaluza futhi ilulama ekuphumuleni.

Uma sisebenzisa i-cellulose ether I-HEMC ngaphakathiI-Skim Coatpowder, ngokuvamile kuzoba nezinkinga, asazi ukuthi kunganikwenzeka ku I-Skim Coatimpushana!

Eyokuqala: Yomisa ngokushesha. Lokhu ngokuyisisekelo inani le-calcium empunga kanye nenani lokugcinwa kwamanzi efayibha, kodwa futhi lihlobene nokomisa kodonga.

Okubili: ikhasi bese ugoqa. Lokhu kuhlobene nesilinganiso sokugcinwa kwamanzi, i-viscosity ephansi ye-cellulose ijwayele lesi simo noma umthamo ophansi.

Ezintathu: powder. Lokhu kuhlobene nenani le-calcium empunga, kodwa futhi nenani le-cellulose kanye nekhwalithi yobuhlobo, ebonakala ngesilinganiso sokugcinwa kwamanzi omkhiqizo, izinga lokugcinwa kwamanzi liphansi, isikhathi sokugeleza kwe-calcium esimpunga asanele, okubangelwa.

Okwesine: amabhamuza. Lokhu kuhlobene nokuswakama okomile kanye flatness odongeni, kodwa futhi kuhlobene ukwakhiwa.

Eyesihlanu: inaliti iphuzu. Lokhu kuhlobene ne-cellulose, ukwakheka kwayo kwefilimu kumpofu, kodwa futhi ukungcola kwe-cellulose ne-gray calcium kunokusabela okuncane, uma ukusabela kunobudlova,I-Skim Coatimpushana izoveza isimo sokusala kukabhontshisi. Awukwazi ukuba odongeni, ngesikhathi esifanayo asikho isibopho, ngaphezu kwe-cellulose ehlanganiswe nemikhiqizo ye-carboxylated nayo ibonakala kulesi simo.

Eyisithupha: imigede yentaba-mlilo kanye nemigodi emincane. Lokhu ngokusobala kuhlobene nokushuba okuphezulu kwe-hydroxyehtyl isixazululo samanzi se-methyl cellulose kanye nokungezwani okungaphezulu kwesixazululo esinamanzi se-hydroxyethyl akubonakali ngokuthola ukwelashwa okulula kuzoba kuhle.

Isikhombisa:I-Skim Coatyomile ngemva kokuqhekeka kalula, ukuphuzi. Lokhu kuhlobene nenani le-calcium empunga, inani le-calcium empunga, okuholela ekwandeni kokuqina kwe-calcium.I-Skim Coati-powder ngemva kokumisa, ukuqina kuphela ngaphandle kokuguquguquka kulula ukuphahlazeka, ikakhulukazi ngamandla angaphandle kulula ukuphahlazeka. Futhi nge-calcium empunga ku-calcium oxide okuqukethwe kuphezulu.

I-Skim Coatisindayo ohlelweni lokukhuhla?

Kulokhu, i-viscosity ye-cellulose iphezulu kakhulu. Abanye abakhiqizi basebenzisa i-cellulose eyizinkulungwane ezingama-200 ukwenza i-putty. II-Skim Coateyenziwe ngale ndlela iphezulu nge-viscosity, ngakho izwakala isindayo lapho ikhuhla. Udonga lwangaphakathi lube nesithukuthezi ngesiphakamiso sengane engeza inani elingu-3, ​​amakhilogremu angu-5, i-viscosity ingu-8, izinkulungwane eziyi-100.

Kungani i-I-Skim Coatnodaka olwenziwe nge-viscosity efanayoI-HEMCcellulose ebusika nasehlobo bazizwa viscosity ihlukile?

Ngenxa ye-gelation eshisayo yomkhiqizo, i-viscosity yomkhiqizo izokwehla kancane kancane ngokunyuka kwezinga lokushisa. Lapho izinga lokushisa lidlula izinga lokushisa lejeli lomkhiqizo, umkhiqizo uzokhishwa emanzini, ngaleyo ndlela ulahlekelwe yi-viscosity. Ehlobo, izinga lokushisa ekamelweni ngokuvamile lingaphezu kwama-degree angu-30, okuhluke kakhulu ekushiseni kwasebusika, ngakho i-viscosity izwa iphansi. Ehlobo, kuphakanyiswa ukuthi ukhethe imikhiqizo ene-viscosity ephakeme noma ukwandisa umthamo we-cellulose, bese ukhetha imikhiqizo enezinga lokushisa eliphezulu le-gel.
