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 yesitashi ether kuya kudaka ayilungile njengaleyo ye-cellulose ether, futhi indlela yokuqina kokubili ihlukile.
3. Ukusebenza kwe-anti-slip
Uma kuqhathaniswa ne-cellulose ethers, i-starch ethers ingakhuphula kakhulu inani lesivuno sokuqala sezinto zokunamathisela zamathayili, ngaleyo ndlela zithuthukise izakhiwo zazo zokulwa nokushelela.
4. Ukungenisa umoya
I-Cellulose ether inendawo eqinile yokungenisa umoya, kuyilapho isitashi ether singenayo indawo yokungenisa umoya.
