I-Methyl cellulose sisishunqulelo se-sodium carboxymethyl cellulose.Isetyenziswa kakhulu ekutyeni, ulwakhiwo, amayeza, iiseramikhi, iibhetri, imigodi, iingubo, ukwenza iphepha, ukuhlamba, i-toothpaste yekhemikhali yemihla ngemihla, ukuprintwa kwe-textile kunye nokudaya, ukugaya 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 afuna ukucutshungulwa 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 kwe-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.
