I-Methyl cellulose sisishunqulelo se-sodium carboxymethyl cellulose. Isetyenziswa kakhulu ekutyeni, kulwakhiwo, kumayeza, iiseramics, iibhetri, imigodi, icoatings, papermaking, ukuhlamba, intlama yamazinyo yekhemikhali yemihla ngemihla, ukuprintwa kwelaphu kunye nokudaya, ukugrumba ioli, njl njl. Umsebenzi ophambili kukusebenza njenge-thickener, i-agent egcina amanzi, i-binder, i-lubricant, i-ejenti yokumisa, i-emulsifier, i-biological product carrier, i-tablet matrix, njl. Ingaba i-methyl cellulose kufuneka ilinganiswe njani ngexesha lokusetyenziswa?
1. I-Methylcellulose ngokwayo i-powder emhlophe eyomileyo, engenakusetyenziswa ngokuthe ngqo kwishishini. Kufuneka inyibilikiswe emanzini kuqala ukuze yenze iglu ecacileyo ye-viscous phambi kokuba ixutywe nodaka ize isetyenziselwe unyango oluthile, olufana nokuncamathisela iithayile.
2. Yintoni umlinganiselo we-methyl cellulose? Umgubo: amanzi kufuneka aqhutywe ngexesha ngokuhambelana nomlinganiselo we-1: 150-200, kwaye emva koko axutywe ngokufanelekileyo, ngelixa udibanisa i-PMC umgubo omile ngelixa uvuselela, kwaye ingasetyenziselwa emva kokusetyenziswa kweyure eli-1.
3. Ukuba i-methyl cellulose isetyenziselwa unyango lwe-concrete interface, umlinganiselo weglue kufuneka ulandele → iglu: i-samente = 1:2.
4. Ukuba i-methyl cellulose isetyenziswa njengodaka lwesamente ukuxhathisa ukuqhekeka, umlinganiselo weglu kufuneka ulandelwe → iglu: isamente: isanti = 1:3:6.
Kufuneka sinikele ingqalelo kwezinye iingxaki xa sisebenzisa i-methyl cellulose:
1. Phambi kokuba usebenzise ngokusesikweni i-methyl cellulose, kufuneka uqale ujonge iinkcukacha kunye neemodeli. Iimodeli ezahlukeneyo zisebenzisa iindlela ezahlukeneyo: xa i-pH> 10 okanye <5, i-viscosity yeglue iphantsi. Ukusebenza yeyona nto izinzile xa i-pH = 7, kwaye i-viscosity iya kunyuka ngokukhawuleza xa izinga lokushisa lingaphantsi kwe-20 ° C; xa izinga lokushisa lingaphezulu kwama-80 ° C, i-colloid iya kuchithwa emva kokufudumeza ixesha elide, kodwa i-viscosity iya kuhla kakhulu.
2. I-Methyl cellulose inokulungiswa ngamanzi abandayo okanye amanzi atshisayo ngokomlinganiselo omiselweyo. Xa ulungiselela, kufuneka udibanise amanzi ngelixa uvuselela. Khumbula ukongeza onke amanzi kunye ne-PMC eyomileyo engumgubo ngexesha elinye. Kuyafaneleka ukuba uqaphele ukuba uluhlu olusisiseko olufuna ukudityaniswa lufanele luhlanjululwe kwangaphambili, kwaye ukungcola okunye, amabala e-oyile, kunye neengqimba ezikhululekile kufuneka zijongwe ngexesha.
