Ngokumalunga nenkqubo yesicelo sobuchwephesha esamkelwe yimveliso yeekhemikhali, kuyimfuneko ukutsala ingqalelo kunye nengqalelo yomqhubi ngamnye wokusebenza, kuba oku kuyisitshixo sokwenza izigqibo ezifanelekileyo kunye nokugqitywa kakuhle kweprojekthi yokwakha nganye.Ukuba indlela yokuyenza inokuthi ichaphazele kakhulu ukusetyenziswa okukhuselekileyo kwemveliso, umzekelo, i-hydroxypropyl methylcellulose, ethandwa kakhulu ngoku kwiinkalo ezahlukeneyo, makhe sijonge kunye ngezantsi.
Ukugcinwa kwamanzi kwe-methylcellulose kuxhomekeke kwisixa sokongeza, i-viscosity, i-particle fineness kunye nesantya sokuchithwa.Ngokuqhelekileyo, ukuba isixa esongezelelweyo sikhulu, i-fineness incinci, kwaye i-viscosity inkulu, izinga lokugcinwa kwamanzi liphezulu.Phakathi kwabo, inani lokongezelela linempembelelo enkulu kwizinga lokugcinwa kwamanzi, kwaye inqanaba le-viscosity alilingani ngokuthe ngqo kwinqanaba lokugcinwa kwamanzi.Izinga lokuchithwa ikakhulu lixhomekeke kwiqondo lokuguqulwa komphezulu wamasuntswana e-cellulose kunye ne-particle fineness.Phakathi kwezi ether ze-cellulose ezingentla, i-methyl cellulose kunye ne-hydroxypropyl methyl cellulose zinezinga eliphezulu lokugcina amanzi.
I-Methylcellulose i-soluble emanzini abandayo, kwaye kuya kuba nzima ukunyibilika emanzini ashushu.Isisombululo sayo samanzi sizinzile kakhulu kuluhlu lwe-pH = 3 ~ 12.Inokuhambelana kakuhle nestatshi, iguar gum, njl njl kunye nee-surfactants ezininzi.Xa iqondo lokushisa lifikelela kwiqondo lokushisa, i-gelation iyenzeka.
Ngokokusetyenziswa okuchanekileyo kwe-hydroxypropyl methylcellulose esikwazisa ngayo ngasentla, kuyimfuneko ukutsala ingqalelo kunye nengqalelo yabasebenzi bonke, ukuze kuqinisekiswe ngcono ukusebenza kwale mveliso yemichiza.
