Zinc oxide ye active agent ekozesebwa ennyo mu kulongoosa emipiira. Mu kukola kapiira, kasasiro n’enkola y’okuddamu okukola ebintu biyinza okufulumya ebirungo bya zinki, ne kireetawo obulabe ku butonde bw’ensi, kale obungi bwa zinki okisayidi mu nkola ya kapiira bulina okukendeezebwa. Active zinc oxide alina obunene bw’obutundutundu obutono, ekitundu ekinene eky’okungulu, omulimu omunene ogw’okufuuka vulcanization, bw’ogeraageranya ne zinc oxide owa bulijjo, obungi bwa zinc oxide active bukendeera, bwe kityo ne kikendeeza ku bulabe bwa zinki eri obutonde bw’ensi, ekiraga emigaso gy’obutonde n’ebyenfuna.
Zinc oxide ya ctive ekolebwa nga ekozesa enkola ennyogovu, okugatta enkuba n’okuyokya, okukola zinc oxide ekola ne zinc oxide omutangaavu, okuwukana ku nkola y’ennono ey’okukankana etali butereevu ekozesebwa abafulumya abalala bangi. Enkola ennyogovu erina diguli ya waggulu ey’obutakyukakyuka mu mutindo, enkola eno era evaamu ekitundu ekinene eky’okungulu ekigere (40m2/g) n’okugabanya obunene bw’obutundutundu obulungi ku mirimu mingi, era obucaafu obutono obw’ebyuma ebizito kye kimu ku bikakasa obutonde bw’ensi mu kintu kino.
Enkola y’okukola enkola y’obubisi eri bweti: Zinc ingot ne sulphuric acid reaction okukola zinc sulfate, n’oluvannyuma okukwatagana kwayo ne sodium carbonate okukola zinc carbonate nga ekintu ekibisi ku zinc oxide. Nga zinc carbonate nga raw material, zinc oxide akolebwa nga banaaza, okukala, okuyola n’okubetenta.
Enkula y’obutundutundu bwa zinki ekola (average particle size of active zinc oxide) eri 50nm, ekitundu ekigere eky’okungulu kinene, nga 40m2/g, ate obutafaali buba bwa njuki, buyitirivu ate nga buyitiridde, kale okusaasaana kuba kulungi; Sipiidi yaayo ey’okusaasaana ya mangu okusinga zinki okisayidi eya bulijjo, ensaasaanya ya kimu, mu nsengekera okulongoosa ekifaananyi ky’okukuŋŋaanyizibwa kw’okuziba kw’amayinja, okusinga kuyinza okukolebwako ddala; Ebyuma ebizito PB2 +, Cu2 +, CD2 +, Mn2 +, Fe2 + ebirimu bitono nnyo, nga bikwatagana n’ebyetaago by’okukuuma obutonde.
Enkozesa y'ebintu .
Zinc oxide mu makolero ga kapiira okusinga ekozesebwa nga rubber vulcanization active agent (accelerating agent), omulimu gwayo kwe kwongera okukola kwa vulcanization accelerator n’okulongoosa vulcanization effect ya rubber. Enkola yaayo ey’okukola ye: zinki okisayidi n’ensengekera y’eddagala ery’okusannyalala okukola omunnyo gwa zinki ogw’okusannyalala; Molekyulu za zinki ne polisufayini ezisannyalala okukola omunnyo gwa zinki ogwa polysulfide; polysulfide zinc salt and rubber macromolecule reaction to complete the final chemical crosslinking, so as to promote the vulcanization of the rubber, activation and strengthening of the role of anti-aging, to achieve stability, processing safety, a large degree of reduction in the defective rate, and to improve the rubber products, tear resistance, abrasion resistance, and increase the fixed elongation of vulcanized rubber, and increase the effect of rubber vulcanization. n’okulongoosa vulcanized rubber stretch stress, okusika amaanyi n’okuwanvuwa, okukendeeza compression permanent deformation, etc.
1. Active zinc oxide mu semi-steel radial tire innerliner okusiiga .
Mu mbeera y’emu, okukozesa sipiidi ya zinki oxide 2 # ensengekera y’okuwonya omupiira okusinga okukozesa zinki okisayidi eya bulijjo 1 # ensengekera ya kapiira keyongera emirundi nga 1; 3 # Formula of active zinc oxide dosage is only 1 # formula of ordinary zinc oxide dosage of 80%, naye sipiidi ya 3 # 3 # ewonya omupiira ekyali ya mangu nnyo okusinga ensengekera ya kapiira l. 3 Ensengeka z’ebintu eby’okukoowoola ebipiira, obuzito bwa Mentni si njawulo nnene.
okugezesa enkola ya vulcanized rubber hardness, constant tensile stress, okusika amaanyi n’amaanyi g’okukutuka okusinga production formula vulcanized rubber okulongooka, okuziyiza obukoowu n’omutindo gw’okukola flexural gugeraageranyizibwa, ebbugumu n’okukaddiwa kw’empewo byakendeera katono.
Active zinc oxide mu kifo kya zinc oxide owabulijjo akozesebwa mu semi-steel radial tire inner ply rubber, okuwonya physical properties za rubber n’okukozesa zinc oxide curing curing level ya bulijjo egeraageranyizibwa ku ya rubber, rubber vulcanization speed is accelerated, ekiyamba okukendeeza ku budde bw’okufuuka vulcanization. Okukozesa zinc oxide active kiyinza okukendeeza ku bungi bwa zinc oxide, nga kikyukakyuka nnyo okusinziira ku byetaago by’okukuuma obutonde.
2. Okusiiga zinc oxide active mu radial tire tread rubber .
Nga okweyongera kw’obungi bwa zinc oxide active, TC10 ne TC90 okutwalira awamu omuze gw’okukula. ML ne MH tebakyusizza nnyo. Kino kitegeeza nti active zinc oxide esobola okukozesebwa mu muwendo ogukendeezeddwa.
Amaanyi g’okusika, okuwanvuwa 100%, okuwanvuwa 300% n’amaanyi g’amaziga ga kapiira tegakyuka nnyo n’okweyongera kw’obungi bwa zinki okisayidi akola. Omuwendo bwe gusukka ebitundu 5, amaanyi g’okukutuka kwa kapiira akayitibwa vulcanized kakendeera inst ead, ekiva ku kweyongera okuyitiridde okwa crosslink density. Oluvannyuma lw’okukaddiwa ku 100 °C× 24h, omutindo gw’okusigala kw’omutindo gw’ekirungo kya kapiira nga gulimu ebitundu 3 ebya zinki okisayidi ebikola y’esinga, era nti n’ebitundu 2.5 eby’eddagala bye bisinga obubi. Ensonga eyinza okuba omuwendo gw’ebitundu 2.5, ensengekera ya vulcanized rubber mesh tetuukiridde, era nga nayo yeeyolekera mu kuwanvuwa kwe kumu ku kukutuka, okukyukakyuka okw’olubeerera ku maziga, okukaluba ku lubalama lw’ennyanja, n’okukola ebbugumu ery’okunyigirizibwa.
Addition of active zinc oxide rubber blend, TC10 and TC90 significantly longer, the minimum torque ML, the maximum torque Mn and the difference between the two MH a ML increase, indicating that its processing safety, vulcanization speed slower, the degree of cross-linking increased, its tensile strength, 100% fixed elongation, 300% fixed elongation and tear strength have been improved, 100 ℃ × 24H Okukaddiwa, eby’obugagga by’ekyokulabirako eby’omuwendo gw’okusigala ennyo oluvannyuma lw’okukaddiwa ku 100 °C× 24h, omuwendo gw’okusigala kw’omulimu gw’ekitundu gulongooseddwa nnyo. Active zinc oxide bw’ekozesebwa mu bungi obukendeezeddwa, enkyukakyuka za TC90 - TS1, enkyukakyuka za ML ne MH si za maanyi, era eby’obutonde eby’ebyuma eby’enkyukakyuka za kapiira eza vulcanized tebyeyoleka; 2.5 Ebitundu by’eddagala, obuziyiza bw’okukaddiwa kwa kapiira akayitibwa vulcanized kakendeera, kale omuwendo guyinza okukendeezebwa okutuuka ku bitundu 3 eby’eddagala erigenda okukozesebwa.
Ebirungi ebiri mu zinc oxide .
Okuyita mu biwandiiko eby’okugezesa eby’ebintu ebyo waggulu, kiyinza okuyigibwa nti zikola zinc oxide esobola okukozesebwa ennyo mu bintu eby’enjawulo ebya kapiira.
(1) Kirina okusaasaana okulungi mu kintu kya kapiira, era eby’obutonde n’eby’ebyuma bilongoosebwa;
(2) mu nkola y’okufuula enseenene. Ekiseera ky’okukookolima eky’ekintu kya kapiira kifuuka ekiwanvu, obukuumi bw’okufuula enseenene bulongooseddwa, era obulungi bw’okufuuka okw’ekika kya vulcanization bulongoosebwa;
(3) Olw’ekitundu ekinene eky’okungulu ekigere n’obunene bw’obutundutundu obutono obwa zinc oxide active , esobola okukozesebwa mu bungi obukendeezeddwa mu kwongerako ebintu ebimu ebya kapiira.
