Isitashi se-ether sisetyenziswa ikakhulu kudaka lolwakhiwo, olunokuthi luchaphazele ukuhambelana kodaka olusekwe kwigypsum, isamente kunye nekalika, kwaye utshintshe ukwakhiwa 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 nezongezo ezininzi kwi-gypsum kunye neemveliso zesamente (njengama-surfactants, i-MC, isitashi kunye ne-polyvinyl acetate kunye nezinye iipolymers ezinyibilikayo emanzini).
Iimpawu eziphambili:
(1) Isitatshi i-ether idla ngokusetyenziswa ngokudibeneyo ne-methyl cellulose ether, ebonisa umphumo omhle we-synergistic phakathi kwezi zibini.Ukongeza ubungakanani obufanelekileyo be-starch ether kwi-methyl cellulose ether kunokuphucula kakhulu ukuxhathisa kwe-sag kunye nokumelana nokutyibilika kodaka, ngexabiso eliphezulu lesivuno.
(2) Ukongeza isixa esifanelekileyo se-ether yesitatshi kudaka oluqulethe i-methyl cellulose ether inokunyusa kakhulu ukuhambelana kodaka kunye nokuphucula umbane, okwenza ulwakhiwo lube lula kwaye ukukhuhla kube lula.
(3) Ukongeza isixa esifanelekileyo se-ether yesitatshi kudaka olune-methyl cellulose ether kunokunyusa ukugcinwa kwamanzi kudaka kunye nokwandisa ixesha elivulekileyo.
(4) Isitatshi se-ether yi-ether eguqulwe ngokwemichiza enyibilikayo emanzini, ehambelana nezinye izongezo kudaka olomileyo lomgubo, olusetyenziswa kakhulu kwizincamathelisi zethayile, udaka lokulungisa, udaka lwe-plaster, i-putty yangaphakathi kunye nengaphandle eludongeni, i-gypsum-based edibeneyo edibeneyo kunye nezinto zokuzalisa. , iiarhente zojongano, udaka lwemasonry.
Iimpawu ze-starch ether ikakhulu zilele: (a) ukuphucula ukuxhathisa kwe-sag;(b) ukuphucula ukusebenza;(c) ukuphucula izinga lokugcinwa kwamanzi eludaka.
Uluhlu losetyenziso:
Isitashi se-ether sifanelekile kuzo zonke iintlobo (isamente, igypsum, i-lime-calcium) yangaphakathi kunye ne-putty yodonga lwangaphandle, kunye nazo zonke iintlobo zodaka olujongene nodaka kunye nodaka lokutyabeka.
Ingasetyenziselwa njengengxube yeemveliso zesamente, iimveliso ezisekelwe kwi-gypsum kunye neemveliso ze-lime-calcium.I-ether yesitatshi inokuhambelana kakuhle nolunye ulwakhiwo kunye nemixube;ifaneleke ngokukodwa ukwakhiwa kwemixube eyomileyo efana nodaka, i-adhesives, i-plastering kunye nezixhobo zokuqengqeleka.Isitatshi ethers kunye methyl cellulose ethers (Tylose MC amabakala) zisetyenziswa kunye kulwakhiwo imixube owomileyo ukunika ukutyeba okuphezulu, isakhiwo esomeleleyo, ukuxhathisa i-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.
