Ngokuthuthuka komphakathi, uhla lokusetshenziswa kwamathayi luya luba banzi futhi luba banzi, akufaki nje kuphela amathuluzi okuthutha endabuko njengamabhayisikili, izimoto, izimoto zezolimo, kodwa futhi okubandakanya imikhiqizo esafufusa efana nezinqola zezingane, izimoto zokudlala, izimoto ezibhalansi, njll. Ukusetshenziswa okuhlukile kunezidingo ezihlukile zokusebenza kwamasondo.Futhi i-magnesium oxide ekhanyayo iyisengezo esibalulekile esingathuthukisa ikhwalithi yamathayi.
Iyini i-magnesium oxide ekhanyayo?
I-magnesium oxide ekhanyayo iyimpushana emhlophe exegayo, engenaphunga, ayinambitheki, futhi engenabuthi.Ivolumu yayo icishe iphindwe kathathu kune-magnesium oxide esindayo, futhi iyinhlanganisela evamile ye-inorganic.I-magnesium oxide ekhanyayo inezinhlobonhlobo zezicelo ezimbonini ezinjengamathayi, irabha, izitsha zobumba, izinto zokwakha, i-metallurgy, imboni yamakhemikhali, ukudla, imithi, njll.
Iyini imisebenzi ye-magnesium oxide ekhanyayo kumathayi?
I-magnesium oxide ekhanyayo ingadlala izindima ezahlukahlukene enqubweni yokukhiqiza amathayi, njenge:
- I-Schorch retarder: vimbela irabha ekushiseni ngokweqile nasekuphekeni ngesikhathi sokucubungula.
- I-Vulcanization accelerator: sheshisa ukusabela kwe-vulcanization futhi uthuthukise ukusebenza kahle kwe-vulcanization.
- Ukumunca i-Acid: nciphisa izinto ezine-asidi enjolweni, vimbela ukuguga nokugqwala.
- Isigcwalisi: khuphula ivolumu kanye nokuminyana kwerabha, unciphise izindleko.
- Ukumelana nokushisa okuphezulu: thuthukisa ukuzinza nokuphepha kwamathayi ezindaweni ezishisa kakhulu.
- Isicishamlilo: nciphisa isivinini esivuthayo kanye nokukhiqizwa kwentuthu kwamathayi lapho uhlangana nomlilo.
- Ukumelana nokugqwala: ukumelana nokuguguleka kwezinto zangaphandle ezinjengomswakama, usawoti, i-asidi ne-alkali.
Ngaphezu kwalokho, i-magnesium oxide ekhanyayo nayo inomsebenzi othile, osiza ukuthuthukisa ukusebenza okuphelele kwamathayi, njenge:
- Nweba isikhathi sokushiswa: khulisa ukuguquguquka nokuqina kwamasondo.
- Lawula okuqukethwe kwerabha nokusebenza kokunamathela: thuthukisa izakhiwo zenjoloba, ibhalansi amandla aqinile kanye nokuguqulwa kokucindezelwa okuguquguqukayo kanye nezinkinga zokukhiqiza ukushisa, wehlise amaphutha ekhwalithi.
- Vimbela ukuqhuma kwesondo nokuhlukaniswa kwehabhu lamasondo: thuthukisa ukuthembeka nokuphepha kwamathayi lapho egijima ngesivinini esikhulu noma umthwalo osindayo.
Yini okufanele ngiyinake lapho ngisebenzisa i-magnesium oxide ekhanyayo?
Nakuba i-magnesium oxide ekhanyayo inezinzuzo eziningi zamathayi, eminye imininingwane kufanele futhi inakwe ngesikhathi sokusetshenziswa ukuze kugwenywe imiphumela emibi, njenge:
- Ukwelashwa kokuvikela umswakama: Uma i-magnesium oxide elula isimanzi, izobangela into engancibiliki i-hydrochloric acid kanye nento encibilikayo emanzini ukuthi ibe phezulu kakhulu, ibangele amabhamuza, iso lesihlabathi nezinye izenzakalo.
- Ukulawulwa kokuqukethwe kwe-Magnesium oxide: okuqukethwe kwe-magnesium oxide ephansi kakhulu kuzothinta ukuqina nokumelana nokugqoka kwamasondo;ukuphakama kakhulu kuzokwandisa ubulukhuni nokuqina, kunciphise ukuqina kanye ne-ductility.
- Ukulawulwa kokuqukethwe kwe-calcium: okuqukethwe kwe-calcium ephezulu kakhulu kuzokwenza amathayi abe brittle futhi athambekele ekuphuke.
- Ukulawulwa komthamo: imithamo emincane kakhulu izonyusa ukuminyana kwe-crosslinking, okuholela ekunciphiseni isikhathi sokushisa kanye nesikhathi esihle sokuvuvukala, kuthinte amandla okuqina kwesondo, ingcindezi enwetshiwe enwetshiwe nobulukhuni, ubude;umthamo omningi uzonciphisa ukuminyana kwe-crosslinking, Okuholela ekushiseni isikhathi eside kanye nesikhathi esihle se-vulcanization, okuthinta ukumelana nokugqoka kwesondo, ukumelana nokuguga nokumelana nowoyela.
Ngakho-ke, lapho ukhetha futhi ugcina ukukhanya kwe-magnesium oxide, kufanele unake ngokukhethekile ekukhetheni izinhlobonhlobo ezifanele kanye nokucaciswa, ukugcina indawo eyomile futhi evalekile, wengeza ngokwesilinganiso esifanele nendlela, ukuze kuzuzwe umphumela omuhle kakhulu we-magnesium oxide ekhanyayo. ngamathayi.
