I-Zinc oxide i-ejenti esetshenziswa kakhulu ekusebenzeni kwenjoloba. Ekukhiqizeni irabha, ukungcola kanye nenqubo yokuphinda usebenzise kabusha kungakhipha amakhompiyutha e-zinc, okulimaza imvelo, ngakho-ke inani le-zinc onide efomula yerabha kufanele lincishiswe. I- activenic oxide inosayizi omncane wezinhlayiyana, indawo enkulu engaphezulu, umsebenzi ophakeme, uma kuqhathaniswa ne-zinc onide ejwayelekile, i- zinc onide esebenzayo iyehliswa, ngaleyo ndlela inciphisa ukulimala kwe-zinc kule ndawo, kukhombisa izinzuzo zemvelo nezomnotho.
I -zinc oxide ye-ctive ikhiqizwa kusetshenziswa inqubo emanzi, inhlanganisela yokugcwala kwezulu nokugazinga, ukukhiqiza i-zinc onide esebenzayo kanye no-zinc onide, ngokungafani nenqubo yendabuko yokubalwa kwe-carvice esetshenziswe abanye abakhiqizi. Inqubo emanzi inezinga eliphakeme lokuvumelana kwekhwalithi, inqubo futhi iphumela endaweni enkulu engaphezulu komhlaba (40m2 / g) nokusatshalaliswa okuphezulu kokuvikeleka kwezicelo eziningi kungenye yeziqinisekiso zezemvelo zalo mkhiqizo walo mkhiqizo.
Inqubo yokukhiqiza yenqubo emanzi yile elandelayo: I-Zinc Ingot kanye ne-Sulfuric Acid Reaction ukukhiqiza i-Zinc Sulfate, bese kuthi lapho khebele nge-sodium carbonate ukukhiqiza i-zinc carbonate ye-zinc onide. NgeZinc Carbonate njengento eluhlaza, uZinc onide ukhiqizwa ukugeza, ukomisa, ukukhala nokuchoboza.
Ubukhulu obujwayelekile bezinhlayiyana ze-zinc oxide busi-50mm, indawo ethile engaphezulu ikhulu, cishe nge-40m2 / g, futhi amakristalu yi-honeycomb, okukhululekile futhi kungukuhlupha, ngakho-ke ukuhlakazwa kulungile; Ijubane layo lokuphazamiseka lishesha kune-zinc oxide ejwayelekile, ukusatshalaliswa kufana, ekuphenduleni ukuthuthukisa into yokuvala i-agglomeration, ngokuyisisekelo kungasabela ngokuphelele; Izinsimbi ezisindayo PB2 +, CU2 +, CD2 +, MN2 +, okuqukethwe kwe-FE2 + kuphansi kakhulu, kuhambisana nezidingo zokuvikelwa kwemvelo.
Ukusetshenziswa Komkhiqizo
I-Zinc onide embonini yerabha isetshenziswa ikakhulukazi njenge-ejenti esebenzayo ye-rubber vulcanization (ukusheshisa i-ejenti), umsebenzi wayo ukuthuthukisa ukusebenza kwe-accelerator ye-vulcanization futhi uthuthukise umphumela we-vulcan werabha. Indlela yayo yokuphendula yile: UZinc onide kanye ne-accelerator Chemical Reaction ukukhiqiza i-accelerator zinc upts; I-accelerator zinks usawoti kanye nama-molecule e-polysulfide ukukhiqiza usawoti we-zinc polysulfide; I-Polysulfide Zinc usawoti kanye ne-ruble macromolecule reaction ukuqeda ukuwela kwamakhemikhali kwamakhemikhali, ukwenza kusebenze futhi ukuqinisa ukuqina, ukucubungula ukuncishiswa kwenjoloba, ukumelana nezilinganiso ze-abrasion, nokukhulisa umphumela we-ruble I-Rubber Vulcanization. Futhi uthuthukise ukucindezelwa kwe-rubber elettle, amandla ashubile kanye nokubumbana, kunciphise ukucindezelwa okungapheli, njll.
1. I-zinc onide ku-semi-steel radial tire innerliner application
Ngokwesilinganiso esifanayo semibandela, ukusetshenziswa kwe-zinc oxide esebenzayo 2 # i-formula yerabha yerabha kunokusetshenziswa kwe-zinc onide okujwayelekile 1 # Irabha lefomula lenyuke cishe izikhathi ezi-1; Ifomula engu-3 # yefomula ye-zinc onide dosage iyifomula eyi-1 # yefomula evamile ye-zinc onide dosage yama-80%, kepha ijubane le-3 # formula yerejishini yerabha iseshesha kakhulu kunefomula yerabha yerabha l. 3 Izakhi zezakhiwo zenjoloba zenjoloba, i-Menni Viscosity ayiwona umehluko omkhulu.
Hlola ifomula yefomula evuthayo, ukucindezelwa okuqhubekayo okuxakile, amandla ashubile kanye namandla okukhiqiza kunefomula yokukhiqiza i-helcanized ethuthukisiwe, ukumelana nokukhathala kanye nokusebenza kokusebenza okuguqukayo kuqhathaniswa kancane.
I-zinc oxide esebenzayo esikhundleni se-zinc oxide ejwayelekile esetshenziswe ku-semi-steel radial tire yangaphakathi ye-ply irabha, i-rubing enjoloba kanye nokusetshenziswa kwe-zinc oning efeberali evukile kuqhathaniswa naleso yerabha, ijubane le-vurcanization asheshiswayo, okulungele ukunciphisa isikhathi se-vulcani. Ukusetshenziswa kwe-uncin oxide esebenzayo kunganciphisa inani le-zinc onide, kuvumelana nezidingo nezidingo zokuvikelwa kwemvelo.
2. Ukusetshenziswa kwe-zinc onide esebenzayo e-radial tire tread
Ngokwanda kwenani le-zinc oxide esebenzayo, i-TC10 ne-TC90 inkambiso yokukhula. I-ML ne-MH azange bashintshe okuningi. Lokhu kusho ukuthi i-zinc oxide esebenzayo ingasetshenziswa ngenani elincishisiwe.
Amandla ashubile, ukugcwala okungu-100%, ukugcwala okungama-300% kanye namandla werabha akuzange kuguquke kakhulu ngokwanda kwenani le-zinc onide esebenzayo. Lapho umthamo udlula izingxenye ezi-5, amandla ashubile e-rubber anciphise i- ead ead, okubangelwa ukwanda ngokweqile kobuningi be-crosslink. Ngemuva kokuguga ngo-100 ℃ × 24h, izinga lokugcina lokusebenza kwerabha elihlanganisiwe elinezingxenye ezi-3 ze -zinc oxide ezisebenzayo kakhulu, nokuthi izingxenye ezingama-2,5 zemithamo zimbi kakhulu. Isizathu singaba inani lezingxenye eziyi-2,5, isakhiwo se-ruble esivunguvuli senjoloba asiphelele, okubuye kuboniswe ekubumbeni okufanayo ezikhathini zamanye amazwe, ukuguquguquka okungapheli kokusebenza kwezinyembezi.
Isengezo se-zinc onide rubber blend, i-TC10 ne-TC90 kakhulu, i-torque mn ephansi, i-degree yokuxhumanisa, i-100% ebekwe phansi, ama-100% ahlelwe kabusha, ama-100 ℃ × 24h agen, Izakhiwo ezikhethekile zamanani okugcinwa kabusha ngemuva kokuguga ngo-100 ℃ × 24h, izinga lokugcina lokusebenza kwe-specimen lithuthukiswa kakhulu. Lapho i-zinc oxide esebenzayo isetshenziswa ngenani elincishisiwe, i-TC90 - Ukuncishiswa kwe-TS1, i-ML ne-MH kanye nezinguquko ze-ML azibalulekile, futhi izakhiwo zemishini zezinguquko zenjoloba evundlekeni azibonakali; 2.5 Izingxenye zomthamo, ukumelana nokuguga kwerabha elivuselelwayo kuyancipha, ngakho-ke inani lingancishiswa libe izingxenye ezi-3 zomthamo okufanele zisetshenziswe.
Izinzuzo ze-zinc oxide
Ngemininingwane yokuhlola yemikhiqizo engenhla, ingafundwa ukuthi i-zinc oxide esebenzayo ingasetshenziswa kabanzi kwimikhiqizo ehlukahlukene yenjoloba.
(1) Inokuhlakazeka okuhle kokuqukethwe kwerabha, kanye nezinto ezingokomzimba nezemishini ziyathuthukiswa;
(2) kwinqubo yokuvuselela. Isikhathi sokukhangisa sezinto zenjoloba siba isikhathi eside, ukuphepha kwe-Vulcan kuyathuthuka, futhi ukusebenza kahle kwe-Vulcan kuyathuthuka;
(3) Ngenxa yendawo enkulu engaphezulu komhlaba kanye nosayizi omncane wezinhlayiyana we -zinc oxide esebenzayo , ingasetshenziswa ngenani elincishisiwe ngokufakwa kwezinto ezithile zenjoloba.
