I-Zinc oxide iyi-ejenti esebenzayo evame ukusetshenziswa ekucubunguleni irabha. Emkhiqizweni wenjoloba, udoti kanye nenqubo yokugaywa kabusha kungase kukhulule izinhlanganisela ze-zinc, okubangela ukulimala endaweni ezungezile, ngakho-ke inani le-zinc oxide kufomula yenjoloba kufanele lincishiswe. i-zinc oxide esebenzayo inosayizi wezinhlayiyana ezincane, indawo enkulu, umsebenzi ophezulu we-vulcanization, uma kuqhathaniswa ne-zinc oxide evamile, inani le -zinc oxide esebenzayo liyancishiswa, ngaleyo ndlela kunciphisa ukulimala kwe-zinc emvelweni, kubonisa izinzuzo zemvelo nezomnotho.
I -zinc oxide esebenzayo ikhiqizwa kusetshenziswa inqubo emanzi, inhlanganisela yemvula nokugazinga, ukukhiqiza i-zinc oxide esebenzayo kanye ne-zinc oxide esobala, ngokuphambene nenqubo yendabuko yokubala engaqondile esetshenziswa abanye abakhiqizi abaningi. Inqubo emanzi inezinga eliphezulu lokungaguquguquki kwekhwalithi, le nqubo iphinde ibangele indawo enkulu ethize (40m2 / g) kanye nokusabalalisa usayizi wezinhlayiyana ezifanele zezinhlelo zokusebenza eziningi, futhi okuqukethwe okuphansi kokungcola kwensimbi esindayo kungenye yeziqinisekiso zemvelo zalo mkhiqizo.
Inqubo yokukhiqiza yenqubo emanzi imi kanje: i-zinc ingot kanye ne-sulfuric acid reaction ukuze kukhiqizwe i-zinc sulfate, bese kuba ukusabela kwayo nge-sodium carbonate ukukhiqiza i-zinc carbonate njengento eluhlaza ye-zinc oxide. Nge-zinc carbonate njengezinto ezingavuthiwe, i-zinc oxide ikhiqizwa ngokuwashwa, ukomiswa, i-calcining nokuchotshozwa.
Ubukhulu bezinhlayiyana ezijwayelekile ze-zinc oxide esebenzayo yi-50nm, indawo ethize nkulu, cishe i-40m2 / g, futhi amakristalu angama-honeycomb, akhululekile futhi ane-porous, ngakho-ke ukuhlakazeka kuhle; ijubane layo lokusabalalisa liyashesha kune-zinc oxide evamile, ukusatshalaliswa kufana, ekuphenduleni ukuthuthukisa isimo se-bridging agglomeration, ngokuyisisekelo singasabela ngokuphelele; izinsimbi ezisindayo Pb2 +, Cu2 +, Cd2 +, Mn2 +, Fe2 + okuqukethwe kuphansi kakhulu, ngokuhambisana nezidingo zokuvikelwa kwemvelo.
Ukusetshenziswa komkhiqizo
I-Zinc oxide embonini yenjoloba isetshenziswa kakhulu njenge-agent esebenzayo ye-rubber vulcanization (i-ejenti esheshayo), umsebenzi wawo owukuthuthukisa ukusebenza kwe-vulcanization accelerator kanye nokwenza ngcono umphumela we-vulcanization wenjoloba. Indlela yayo yokusabela yile: i-zinc oxide kanye ne-accelerator chemical reaction ukukhiqiza usawoti we-zinc accelerator; i-accelerator zinc usawoti kanye ne-polysulfide molecule ukukhiqiza i-polysulfide zinc usawoti; i-polysulfide zinc usawoti kanye ne-rubber macromolecule yokusabela ukuqedela i-crosslinking yamakhemikhali yokugcina, ukuze kuthuthukiswe i-vulcanization yenjoloba, ukusebenza nokuqiniswa kwendima ye-anti-aging, ukufeza ukuzinza, ukucubungula ukuphepha, izinga elikhulu lokunciphisa izinga elingalungile, nokuthuthukisa imikhiqizo yenjoloba, ukumelana nezinyembezi, ukumelana ne-abrasion, nokwandisa umphumela we-rubber omisiwe, i-vulcan vulcanization. Futhi uthuthukise ukucindezelwa okunwebeka kwenjoloba, amandla aqinile kanye nokwelula, unciphise ukuguquguquka okungapheli kokucindezelwa, njll.
1. I-zinc oxide esebenzayo kuhlelo lwe-semi-steel radial innerliner yangaphakathi
Ngenani elifanayo lezimo, ukusetshenziswa kwe-zinc oxide esebenzayo 2 # ijubane lokuphulukisa irabha yefomula kunokusetshenziswa kwe-zinc oxide evamile 1 # irabha yefomula inyuke cishe izikhathi ezi-1; I-3 # ifomula yomthamo osebenzayo we-zinc oxide ingu-1 # ifomula yomthamo ojwayelekile we-zinc oxide engu-80%, kodwa isivinini sokuphulukisa irabha yefomula engu-3 # sisashesha kakhulu kunefomula yerabha l. Ukwakhiwa kwe-3 kwezakhiwo ze-rubber coking, i-viscosity ye-Menni ayiwona umehluko omkhulu.
Ifomula yokuhlola evundlile ubulukhuni benjoloba, ingcindezi eqinile eqinile, amandla okunyakazisa kanye namandla okudabula kunefomula yokukhiqiza yenjoloba ethuthukisiwe ethuthukisiwe, ukumelana nokukhathala kanye nezinga lokusebenza okuguquguqukayo kuyaqhathaniswa, ukusebenza kokushisa nomoya ukuguga kwehle kancane.
i-zinc oxide esebenzayo esikhundleni se-zinc oxide evamile esetshenziswa ku-semi-steel radial tire inner ply rubber, ukuphulukisa izakhiwo zomzimba zenjoloba kanye nokusetshenziswa kwezinga lenjoloba elivamile le-zinc oxide liqhathaniswa nelenjoloba, isivinini se-rubber vulcanization siyashesha, esiza ukunciphisa isikhathi se-vulcanization. Ukusetshenziswa kwe-zinc oxide esebenzayo kunganciphisa inani le-zinc oxide, livumelane nezimo ezidingekayo zokuvikelwa kwemvelo.
2. Ukusetshenziswa kwe-zinc oxide esebenzayo kunjoloba enyathela ngamasondo e-radial
Ngokukhula kwenani le-zinc oxide esebenzayo, i-TC10 ne-TC90 umkhuba jikelele wokukhula. I-ML ne-MH ayizange ishintshe kakhulu. Lokhu kusho ukuthi i-zinc oxide esebenzayo ingasetshenziswa ngenani elincishisiwe.
Amandla aqinile, ukunwetshwa okungu-100%, ukunwebeka okungu-300% namandla okudabula kwerabha akuzange kushintshe kakhulu ngokwanda kwenani le-zinc oxide esebenzayo. Uma umthamo udlula izingxenye ezi-5, amandla okudabula enjoloba ethintekile ayancipha ngokushesha , okubangelwa ukwanda ngokweqile kokuminyana kwe-crosslink. Ngemva kokuguga ku-100 ℃× 24h, izinga lokugcinwa kokusebenza kwenhlanganisela yenjoloba enezingxenye ezi-3 ze -zinc oxide esebenzayo lingcono kakhulu, futhi lokho ngezingxenye ezingu-2.5 zomthamo yikona okubi kakhulu. Isizathu singase sibe inani lezingxenye ezingu-2.5, ukwakheka kwe-rabha enezikhala zenjoloba ezivuvukele akuphelele, okubuye kubonakale ekwelulweni okufanayo lapho kudabukelwa, ukuwohloka okungapheli kokudabuka, ukuqina kogu, nokusebenza kokukhiqiza ukushisa kokucindezelwa.
Ukwengezwa kwenhlanganisela yenjoloba esebenzayo ye-zinc oxide, i-TC10 ne-TC90 isikhathi eside kakhulu, i-torque ML encane, i-torque ephezulu engu-Mn kanye nomehluko phakathi kokunyuka kwe-MH kuya kwe-ML, okubonisa ukuthi ukuphepha kwayo kokucubungula, isivinini se -vulcanization sihamba kancane, izinga lokuxhumanisa likhuphuka, amandla alo aqinile, i-100% i-elongation engaguquki kanye ne-30% fixed elongation, 30 100 ℃ × 24h ukuguga, izici zesifanekiso sezinga lokugcinwa ngokuphawulekayo Ngemva kokuguga ku-100 ℃× 24h, izinga lokugcinwa kokusebenza kwesifanekiso liyathuthukiswa kakhulu. Lapho i-zinc oxide esebenzayo isetshenziswa ngenani elincishisiwe, i-TC90 - TS1 ifinyeza, izinguquko ze-ML ne-MH azibaluleki, futhi izakhiwo zemishini yezinguquko zenjoloba ezivundile azibonakali; Izingxenye ezingu-2.5 zomthamo, ukumelana nokuguga kwerabha ehlanjululwe kuncipha, ngakho inani lingancishiswa libe izingxenye ezi-3 zomthamo ozosetshenziswa.
Izinzuzo ze-zinc oxide
Ngokusebenzisa idatha yokuhlola yemikhiqizo engenhla, kungafundwa ukuthi i-zinc oxide esebenzayo ingasetshenziswa kabanzi emikhiqizweni yenjoloba ehlukahlukene.
(1) Inokusabalalisa okuhle ezintweni zenjoloba, futhi izakhiwo zomzimba nezomshini ziyathuthukiswa;
(2) Enqubweni ye-vulcanization. Isikhathi sokupheka se-rubber material siba side, ukuphepha kwe-vulcanization kuyathuthukiswa, futhi ukusebenza kahle kwe-vulcanization kuyathuthukiswa;
(3) Ngenxa yendawo enkulu ethize kanye nosayizi omncane wezinhlayiyana ze -zinc oxide esebenzayo , ingasetshenziswa ngenani elincishisiwe ekufakweni kwezinye izinto zenjoloba.
