I-starch ether isetyenziswa kakhulu kwi-construction mortar, nto leyo enokuchaphazela ukuhambelana kwe-mortar ngokusekelwe kwi-gypsum, isamente kunye ne-lime, kwaye itshintshe ukwakhiwa kunye nokumelana nokuwa kwe-mortar. I-starch ethers idla ngokusetyenziswa kunye ne-non-modified and modified cellulose ethers. Ifanelekile kwiinkqubo ezingathathi hlangothi kunye ne-alkaline, kwaye iyahambelana nezinye izongezo ezininzi kwi-gypsum kunye neemveliso zesamente (ezifana ne-surfactants, i-MC, i-starch kunye ne-polyvinyl acetate kunye nezinye ii-polymers ezinyibilikayo emanzini).
Iimpawu eziphambili:
(1) I-starch ether idla ngokusetyenziswa kunye ne-methyl cellulose ether, ebonisa isiphumo esihle sokusebenzisana phakathi kwezi zimbini. Ukongeza isixa esifanelekileyo se-starch ether kwi-methyl cellulose ether kunokuphucula kakhulu ukumelana nokungatyibiliki kwe-mortar, ngexabiso eliphezulu lemveliso.
(2) Ukongeza isixa esifanelekileyo se-starch ether kwi-mortar equlethe i-methyl cellulose ether kunokunyusa kakhulu ukuhambelana kwe-mortar kwaye kuphucule ukugeleza kwayo, okwenza ulwakhiwo lube lula kwaye ukukrwela kube lula.
(3) Ukongeza isixa esifanelekileyo se-starch ether kwi-mortar equlethe i-methyl cellulose ether kunokunyusa ukugcinwa kwamanzi kwi-mortar kwaye kwandise ixesha lokuvula.
(4) I-starch ether yi-starch ether eguqulwe ngokweekhemikhali enyibilikayo emanzini, iyahambelana nezinye izongezo kwi-dry powder mortar, isetyenziswa kakhulu kwi-tile adhesives, i-repair mortar, i-plaster plaster, i-interior and external wall putty, i-gypsum-based embedded Joints and filling materials, ii-interface agents, i-masonry mortar.
Iimpawu ze-starch ether zilele kakhulu kwezi: (a) ukuphucula ukumelana nokuwa; (b) ukuphucula ukusebenza; (c) ukuphucula izinga lokugcina amanzi kwi-mortar.
Uluhlu lokusetyenziswa:
I-starch ether ifanelekile kuzo zonke iintlobo ze-(samente, i-gypsum, i-lime-calcium) i-wall putty yangaphakathi nangaphandle, kunye nazo zonke iintlobo ze-facing mortar kunye ne-plastering mortar.
Ingasetyenziswa njengomxube weemveliso ezisekwe kwisamente, iimveliso ezisekwe kwi-gypsum kunye neemveliso ze-lime-calcium. I-starch ether ihambelana kakuhle nezinye izinto zokwakha kunye nezinto ezidityanisiweyo; ifanelekile ngakumbi kwiingxube ezomileyo zokwakha ezifana nodaka, izinto zokuncamathelisa, izinto zokuplasta kunye nezinto zokuqengqeleka. Ii-starch ethers kunye nee-methyl cellulose ethers (ii-Tylose MC grades) zisetyenziswa kunye kwiingxube ezomileyo zokwakha ukunika ukuqina okuphezulu, ulwakhiwo oluqinileyo, ukumelana nokuwa kunye nokulula kokuphathwa. I-viscosity yee-mortars, ii-adhesives, ii-plasters kunye nee-roll renders eziqulethe ii-methyl cellulose ethers eziphezulu zinokuncitshiswa ngokongezwa kwee-starch ethers.
