Isitashi i-ether yigama elivamile lekilasi lesitashi esiguquliwe esiqukethe izibopho ze-ether ku-molecule, eyaziwa nangokuthi isitashi se-etherified, esisetshenziswa kakhulu kwezokwelapha, ukudla, izindwangu, ukwenza iphepha, amakhemikhali ansuku zonke, i-petroleum nezinye izimboni.Namuhla sichaza ikakhulukazi indima yesitashi ether odakeni:
1) Khulisa udaka, ukhuphule i-anti-sagging, anti-sagging kanye nezakhiwo ze-rheological zodaka.
Isibonelo, ekwakhiweni kwe-adhesive tile, putty, kanye ne-plastering mortar, ikakhulukazi manje lapho ukufafaza ngomshini kudinga uketshezi oluningi, njengodaka olusekelwe ku-gypsum, kubaluleke kakhulu (i-gypsum efafazwe ngomshini idinga ukumanzi okuphezulu kodwa izobangela ukuwohloka okukhulu. , isitashi sika-Ether singenza lokhu kuntuleka).Okusho ukuthi, lapho kusetshenziswa amandla angaphandle, i-viscosity iyancipha, ithuthukise ukusebenza nokusebenza kahle, futhi lapho amandla angaphandle ehoxiswa, i-viscosity iyanda, ithuthukise ukumelana nokugoqa.Ngomkhuba wamanje wokwanda kwendawo yamathayili, ukwengeza isitashi ether kungathuthukisa ukumelana nokushelela kokunamathela kwethayela.
2) Amahora okuvula anwetshiwe
Ngezinto zokunamathisela zamathayili, zingahlangabezana nezidingo zokunamathisela okukhethekile kwamathayela (I-Class E, i-20min enwetshwe ku-30min ukuze ifinyelele ku-0.5MPa) enweba isikhathi sokuvula.Isitashi i-ether singenza ingaphezulu lesisekelo segypsum nosimende bushelelezi, kube lula ukulisebenzisa, futhi linomphumela omuhle wokuhlobisa.Kubaluleke kakhulu ukuplasta udaka nodaka oluncane lokuhlobisa olufana ne-putty.
1. I-ether yesitashi ingathuthukisa ngempumelelo izakhiwo zokulwa nokushelela kanye nokushelela kodaka
I-cellulose ether ngokuvamile ingathuthukisa kuphela i-viscosity nokugcinwa kwamanzi kwesistimu kodwa ayikwazi ukuthuthukisa izakhiwo zokulwa nokucwila kanye nokunqanda ukushelela.
2. Ukuqina kanye ne-viscosity
Ngokuvamile, i-viscosity ye-cellulose ether icishe ibe amashumi ezinkulungwane, kuyilapho i-viscosity yesitashi ether ingamakhulu amaningana kuya ezinkulungwaneni ezimbalwa, kodwa lokhu akusho ukuthi ukuqina kwempahla ye-starch ether kuya kudaka ayilungile njengaleyo ye-cellulose ether, futhi indlela yokuqina kokubili ihlukile.
3. Ukusebenza kwe-anti-slip
Uma kuqhathaniswa nama-cellulose ethers, i-starch ethers ingakhuphula ngokuphawulekayo inani lesivuno sokuqala sokunamathelisa amathayili, ngaleyo ndlela ithuthukise izakhiwo zabo zokulwa nokushelela.
4. Ukungenisa umoya
I-Cellulose ether inendawo eqinile yokungenisa umoya, kuyilapho isitashi ether singenayo indawo yokungenisa umoya.
