Isitatshi etherisetyenziswa ikakhulu kudaka lolwakhiwo, olunokuthi luchaphazele ukuhambelana kodaka olusekelwe kwi-gypsum, i-samente kunye nekalika, kwaye utshintshe ulwakhiwo kunye nokumelana nodaka lodaka. Ii-ethers zesitatshi zidla ngokusetyenziswa kunye ne-ethers ye-cellulose engaguqukiyo kunye ne-modified. Ifanelekile kwiinkqubo zombini ezingathathi hlangothi kunye ne-alkaline, kwaye iyahambelana nezona zongezo kwi-gypsum kunye neemveliso zesamente (ezifana ne-surfactants, i-MC, isitashi kunye ne-polymers e-soluble yamanzi njenge-polyvinyl acetate).
Umsebenzi ophambili
(1) Isakhono esihle sokuqina ngokukhawuleza: i-viscosity ephakathi, ukugcinwa kwamanzi aphezulu;
(2) Ithamo lincinci, kwaye ithamo eliphantsi linokuba nesiphumo esihle;
(3) Ukuphucula ukukwazi ukulwa ne-sag yezinto ngokwayo;
(4) Ine-lubricity elungileyo, enokuphucula ukusebenza kwesixhobo kunye nokwenza umsebenzi ube lula.
Main features
Iimpawu ze-starch ether ikakhulu zikwi:
(a) Ukuphucula ukuxhathisa kwe-sag;
(b) Ukuphucula ukwakheka;
(c) Ukuphucula ukugcinwa kwamanzi kwidaka.
Intsebenziswano
Isitatshi i-ether idla ngokusetyenziswa kunye ne-methyl cellulose ether, ebonisa umphumo omhle we-synergistic phakathi kwezi zibini. Ukongeza isixa esifanelekileyo se-ether yesitatshi kwi-methyl cellulose ether kunokuphucula kakhulu ukuxhathisa kwe-sag kunye nokumelana nokutyibilika kodaka. Ixabiso lesivuno esiphezulu.
Kwi-mortar equkethe i-methyl cellulose ether, ukongeza inani elifanelekileyo le-starch ether inokunyusa kakhulu ukuhambelana kodaka kunye nokuphucula umbane, okwenza ukwakhiwa kube lula kunye nokukhuhla kakuhle.
Kumdaka oqulethe i-methyl cellulose ether, ukongeza inani elifanelekileyo le-starch ether kunokunyusa ukugcinwa kwamanzi kwi-mortar kunye nokwandisa ixesha elivulekileyo.
Isitashi se-ether yi-ether eguqulwa ngamachiza e-starch e-soluble emanzini, ehambelana nezinye izongezo kwi-powder mortar eyomileyo, esetyenziswa ngokubanzi kwi-adhesives ye-tile, ukulungiswa kodaka, i-plaster plaster, i-putty yangaphakathi kunye yangaphandle yodonga, i-gypsum-based caulking and filling Materials, i-interface agents, udaka lwamatye.
Isitashi se-etere silungele zonke iintlobo (isamente, igypsum, i-lime calcium-based) yangaphakathi kunye ne-putty yodonga lwangaphandle, kunye neentlobo ezahlukeneyo zokujongana nodaka lokutyabeka udaka.
Ingasetyenziselwa njengengxube yeemveliso ezisekelwe kwisamente, iimveliso ezisekelwe kwi-gypsum kunye neemveliso ze-lime-calcium. Isitatshi se-ether sihambelana kakuhle nolunye ulwakhiwo kunye nemixube; ilungele ukwakhiwa kwemixube eyomileyo efana nodaka, izinto zokuncamathelisa, ukutyabeka kunye nezinto zokuqengqeleka. Isitatshi ether kunye nemethyl cellulose ether (KimaCellMC grade) zisetyenziswa kunye ekwakheni imixube eyomileyo ukunika ukutyeba okuphezulu, ulwakhiwo olomeleleyo, ukuxhathisa kwe-sag kunye nokulula ukuphatha. I-viscosity ye-mortars, i-adhesives, i-plasters kunye ne-roll renders equkethe i-methyl cellulose ethers ephezulu inokuncitshiswa ngokongezwa kwe-starch ethers.
