Incazelo Yomkhiqizo:
I-Methyl Hydroxyethyl Cellulose (MHEC) iyi-ether engeyona ionic cellulose esetshenziswa kakhulu ezintweni zokwakha. Ingancibilika emanzini ashisayo noma abandayo ukuze kwakheke isixazululo esisobala nge-viscosity ethile. Izakhiwo ze-methyl hydroxyethyl cellulose ne-methylcellulose ziyafana, kodwa ukuba khona kwe-hydroxyethyl kwenza i-MHEC cellulose inyibilike kakhulu emanzini, isisombululo sihambisana kakhulu nosawoti futhi sinezinga lokushisa eliphakeme lokuhlanganisa.
Isicelo:
I-MHEC cellulose powder isetshenziswa kabanzi embonini yokwakha. Isibonelo, ingasetshenziswa ku-adhesive tile, i-joint filler, i-self-leveling mortar, i-plaster, i-skim coat, upende kanye nama-coatings, njll. Njenge-non-ionic cellulose ether, i-HMEC powder inomphumela omuhle wokuzinzisa kanye nokuqina kupende, okungenza upende ukhiqize ukumelana okuhle kokugqoka. I-lubricity ye-MHEC cellulose ingathuthukisa kakhulu ukusebenza kodaka (njengokuthuthukisa amandla esibopho sodaka, ukunciphisa ukumuncwa kwamanzi, nokuthuthukisa i-anti-sag of mortar), okuwusizo ekuthuthukiseni ukusebenza kahle komsebenzi.
Ngaphandle kwemboni yezokwakha, i-methyl hydroxyethyl cellulose nayo isetshenziswa embonini yokudla, kumakhemikhali ansuku zonke, nakweminye imikhakha. Embonini yokudla, i-HEMC cellulose isetshenziswa njenge-adhesion, emulsification, ukwakheka kwefilimu, ukuqina, ukumisa, ukusabalalisa, ama-agent okugcina amanzi, njll. Kumakhemikhali ansuku zonke, isetshenziswa njengesengezo sokuxubha amazinyo, izimonyo, kanye ne-detergent.
Iphakheji: 25 kgs/isikhwama noma njengoba ucela.
Isitoreji: Gcina endaweni engenawo umoya, eyomile.
Amazinga asetshenzisiwe: Izinga lamazwe ngamazwe.
