Ingcaciso yeMveliso:
I-Methyl Hydroxyethyl Cellulose (MHEC) yi-ether ye-cellulose e-non-ionic esetyenziswa ngokubanzi kwizinto zokwakha. Inokuchithwa emanzini ashushu okanye abandayo ukwenza isisombululo esicacileyo kunye ne-viscosity ethile. Iipropati ze-methyl hydroxyethyl cellulose kunye ne-methylcellulose zifana, kodwa ubukho be-hydroxyethyl benza i-cellulose ye-MHEC idibanise ngakumbi emanzini, isisombululo sihambelana kakhulu netyuwa kwaye sinobushushu obuphezulu bokudibanisa.
Isicelo:
I-MHEC i-cellulose powder isetyenziswa ngokubanzi kwishishini lokwakha. Ngokomzekelo, inokusetyenziswa kwi-adhesive tile, i-joint filler, i-self-leveling mortar, i-plaster, i-skim coat, ipeyinti kunye neengubo, njl. Njenge-ionic cellulose ether, i-HMEC powder inefuthe elihle lokuzinzisa kunye nokuqina kwipende, enokwenza ipeyinti ivelise ukuxhathisa okulungileyo kokunxiba. I-lubricity ye-MHEC cellulose inokuphucula kakhulu ukusebenza kodaka (njengokuphucula amandla ebhondi yodaka, ukunciphisa ukunyuswa kwamanzi, kunye nokuphucula i-anti-sag of mortar), eluncedo ekuphuculeni ukusebenza kakuhle.
Ngaphandle kweshishini lokwakha, i-methyl hydroxyethyl cellulose ikwasetyenziswa kushishino lokutya, imichiza yemihla ngemihla, kunye nezinye iindawo. Kwishishini lokutya, i-HEMC cellulose isetyenziselwa ukunamathela, i-emulsification, ukubunjwa kwefilimu, ukuqina, ukumisa, ukusabalalisa, ii-agent zokugcina amanzi, njl. Kwiikhemikhali zemihla ngemihla, isetyenziswe njengesongezo sokuxutywa kwamazinyo, izimonyo kunye ne-detergent.
Iphakheji: 25 kgs / ibhegi okanye njengoko ucela.
Ugcino: Gcina kwindawo engenamoya, eyomileyo.
Imigangatho eyenziweyo: iMigangatho yeHlabathi.
