I-Methyl cellulose isifinyezo se-sodium carboxymethyl cellulose.Isetshenziselwa ikakhulukazi ukudla, ukwakhiwa, imithi, izitsha zobumba, amabhethri, izimayini, okokugqoka, ukwenza amaphepha, ukuwasha, umuthi wokuxubha amakhemikhali wansuku zonke, ukuphrinta izindwangu nokudaya, ukumba uwoyela, njll. ngaphakathi kwensimu.Umsebenzi oyinhloko ukusebenza njenge-thickener, i-ejenti egcina amanzi, i-binder, i-lubricant, i-ejenti elengayo, i-emulsifier, inkampani ye-biological product, i-tablet matrix, njll. Kufanele ilinganiswe kanjani i-methyl cellulose ngesikhathi sokusetshenziswa?
1. I-Methylcellulose ngokwayo iyimpuphu emhlophe eyomile, engakwazi ukusetshenziswa ngokuqondile embonini.Idinga ukuncibilika emanzini kuqala ukuze yakhe ingcina ye-viscous ekhanyelayo ngaphambi kokuthi ixutshwe nodaka bese isetshenziselwe ukwelapha okuthile, njengokunamathisela amathayili.
2. Ingakanani isilinganiso se-methyl cellulose?I-Powder: amanzi adinga ukucutshungulwa ngesikhathi ngokwesilinganiso se-1: 150-200, bese exutshwa ngokwenziwa, ngenkathi enezela i-PMC powder eyomile ngenkathi ivuselela, futhi ingasetshenziswa ngemva kokusetshenziswa kwehora elingu-1.
3. Uma i-methyl cellulose isetshenziselwa ukwelashwa kwesixhumi esibonakalayo, isilinganiso seglue sidinga ukulandela → ingcina: usimende = 1:2.
4. Uma i-methyl cellulose isetshenziswa njengodaka lukasimende ukumelana nokuqhekeka, kufanele kulandelwe isilinganiso seglue → ingcina: usimende: isihlabathi = 1:3:6.
Kudingeka sinake izinkinga ezithile lapho sisebenzisa i-methyl cellulose:
1. Ngaphambi kokusebenzisa ngokusemthethweni i-methyl cellulose, kufanele uqale ubheke imininingwane namamodeli.Amamodeli ahlukene asebenzisa izindlela ezahlukene: lapho i-pH> 10 noma <5, i-viscosity yeglue iphansi kakhulu.Ukusebenza kuzinzile kakhulu uma i-pH=7, futhi i-viscosity izokhuphuka ngokushesha lapho izinga lokushisa lingaphansi kuka-20°C;lapho izinga lokushisa lingaphezu kuka-80 ° C, i-colloid izokhishwa ngemuva kokushisa isikhathi eside, kodwa i-viscosity izokwehla kakhulu.
2. I-Methyl cellulose ingalungiswa ngamanzi abandayo noma amanzi ashisayo ngokwesilinganiso esinqunyiwe.Lapho ulungiselela, udinga ukwengeza amanzi ngenkathi uvuselela.Khumbula ukwengeza wonke amanzi kanye nempushana eyomile ye-PMC ngesikhathi esisodwa.Kuyaphawuleka ukuthi ungqimba oluyisisekelo oludinga ukuboshwa kufanele luhlanzwe kusengaphambili, futhi okunye ukungcola, amabala amafutha, nezingqimba ezivulekile kudingeka kubhekwane nazo ngesikhathi.
