Zinc oxide inowanzoshandiswa inoshanda mukugadzira rabha. Mukugadzirwa kwerabha, marara uye nzira yekudzokorodza inogona kuburitsa zinc makomisheni, zvichikonzera kukuvadza kune zvakatipoteredza, saka huwandu hwezinc oxide mufomura yerabha hunofanira kudzikiswa. inoshanda zinc oxide ine diki diki saizi, yakakura pamusoro penzvimbo, yakakwira vulcanization chiitiko, zvichienzaniswa neyakajairika zinc oxide, huwandu hweinoshanda zinc oxide hunodzikiswa, nokudaro kuderedza kukuvadzwa kwezinc kune zvakatipoteredza, zvichiratidza zvakatipoteredza uye zvehupfumi.
A ctive zinc oxide inogadzirwa uchishandisa nzira yekunyorova, musanganiswa wemvura uye kugocha, kugadzira inoshanda zinc oxide uye yakajeka zinc oxide, zvinopesana neyakajairwa isina kunanga calcination process inoshandiswa nevamwe vagadziri vakawanda. Iyo yakanyorova ine dhigirii yakakura yekusagadzikana mumhando, iyo nzira inokonzeresa yakakura chaiyo nzvimbo (40m2 / g) uye yakakwana particle size kugovera kune akawanda maapplication, uye iyo yakaderera yemukati yeheavy metal tsvina ndeimwe yezvakatipoteredza vimbiso yechigadzirwa ichi.
Magadzirirwo ekugadzirwa kwekunyorova ndeaya anotevera: zinc ingot uye sulfuric acid reaction kugadzira zinc sulfate, uyezve kuita kwayo ne sodium carbonate kugadzira zinc carbonate seyakabikwa ye zinc oxide. Ne zinc carbonate seyakagadzirwa, zinc oxide inogadzirwa nekugeza, kuomesa, calcining uye kupwanya.
Ivhareji yehukuru hwezinc oxide inoshanda 50nm, iyo nzvimbo chaiyo yakakura, inenge 40m2 / g, uye makristasi ari muzinga weuchi, akasununguka uye ane porous, saka kupararira kwakanaka; kumhanya kwayo kwekupararira inokurumidza kupfuura yakajairwa zinc oxide, kugovera kwakafanana, mukuita kwekuvandudza chiitiko chebridging agglomeration, inogona kuitwa zvachose; heavy metals Pb2 +, Cu2 +, Cd2 +, Mn2 +, Fe2 + content yakaderera zvikuru, maererano nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza.
Product Use
Zinc oxide muindasitiri yerabha inonyanya kushandiswa seyerubha vulcanization inoshanda mumiriri (inomhanyisa mumiriri), basa rayo nderekuwedzera activation yevulcanization accelerator uye kugadzirisa vulcanization mhedzisiro yerabha. Maitiro ayo ekuita ndeye: zinc oxide uye accelerator kemikari reaction kuti ibudise accelerator zinc munyu; accelerator zinc munyu uye polysulfide mamorekuru kugadzira polysulfide zinc munyu; polysulfide zinc munyu uye rubber macromolecule reaction kuti ipedze iyo yekupedzisira kemikari crosslinking, kuitira kusimudzira vulcanization yerabha, activation uye kusimbaradza basa rekurwisa kuchembera, kuwana kugadzikana, kugadzirisa kuchengetedzwa, kuderedzwa kukuru kwechiyero chakakanganisika, uye kuvandudza zvigadzirwa zverabha, kubvarura kuramba, abrasion kuramba, uye kuwedzera yakagadziriswa erubha mhedzisiro, vulcan mhedzisiro. vulcanization. Uye kunatsiridza vulcanized rabha kutambanudza kushushikana, kusimba simba uye kurebesa, kuderedza compression zvachose deformation, nezvimwe.
1. Active zinc oxide mu semi-steel radial tire innerliner application
Muhuwandu hwakafanana hwemamiriro, kushandiswa kweiyo inoshanda zinc oxide 2 # formula rubber kuporesa kukurumidza kupfuura kushandiswa kweakajairika zinc oxide 1 # formula rubber yakawedzera kanenge ka1; 3 # formula yeinoshanda zinc oxide dosage ingori 1 # fomula yeyakajairwa zinc oxide dosage ye80%, asi iyo 3 # formula yerabha yekurapa kumhanya ichiri kukurumidza kupfuura fomula yerabha l. 3 kuumbwa kwerubha coking zvivakwa, iyo Menni viscosity haina misiyano yakawanda.
Muedzo formula vulcanized rabha kuomarara, kuramba kusimba kushushikana, kusimba simba uye kubvarura simba kupfuura yekugadzira fomula vulcanized rabha yakagadziridzwa, kuneta kuramba uye flexural performance level inofananidzwa, kupisa uye kuchembera kwemhepo kuita kwakadzikira zvishoma.
inoshanda zinc oxide pachinzvimbo cheyakajairika zinc oxide inoshandiswa mu semi-simbi radial tire yemukati ply rabha, kurapa rabha yemuviri zvimiro uye kushandiswa kweyakajairwa zinc oxide kurapa rubber level inofananidzwa neiyo yerabha, rabha vulcanization yekumhanyisa inokwidziridzwa, izvo zvinobatsira kupfupisa iyo vulcanization nguva. Kushandiswa kwekushanda zinc oxide kunogona kuderedza kuwanda kwezinc oxide, kunyanya kuenderana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza.
2. Kushandiswa kwekushanda zinc oxide mu radial tire tread rubber
Nekuwedzera kwehuwandu hwekushanda zinc oxide, TC10 uye TC90 yakazara maitiro ekukura. ML neMH hazvina kuchinja zvakanyanya. Izvi zvinoreva kuti inoshanda zinc oxide inogona kushandiswa muhuwandu hwakaderedzwa.
Simba rekusimba, 100% elongation, 300% elongation uye kubvarura simba rerabha harina kuchinja zvakanyanya nekuwedzera kwehuwandu hwezinc oxide inoshanda. Kana iyo dosi inodarika zvikamu zvishanu, simba rekubvaruka rerubha rakasvibiswa rinodzikira inst ead, izvo zvinokonzerwa nekuwedzera kwakanyanya kwecrosslink density. Mushure mekuchembera pa100 ℃ × 24h, chiyero chekuchengetedza kwekuita kwekomboni yerubha ine zvikamu zvitatu zvezinc oxide inoshanda ndiyo yakanyanya kunaka, uye iyo ine 2.5 zvikamu zvedosi ndiyo yakaipisisa. Chikonzero chinogona kunge chiri huwandu hwezvikamu 2.5, iyo vulcanized rubber mesh chimiro haina kukwana, iyo inoratidzwa zvakare mukurebesa kwakafanana pakubvarura, deformation yekusingaperi pakubvarura, kuoma kweShore, uye kudzvanya chizvarwa chekuita.
Kuwedzerwa kweiyo inoshanda zinc oxide rubber musanganiswa, TC10 uye TC90 zvakanyanya kureba, iyo shoma torque ML, iyo yakanyanya torque Mn uye mutsauko pakati peaviri MH a ML kuwedzera, zvichiratidza kuti kuchengetedzwa kwayo, vulcanization inononoka inononoka, dhigirii rekuyambuka-kubatanidza rakawedzera, simba rayo rekusimba, 100% yakagadziriswa kureba, 30% yakagadziriswa elongation, 30 100 ℃ × 24h kuchembera, maitiro emuenzaniso weyero yekuchengetedza zvakanyanya Mushure mekuchembera pa100 ℃ × 24h, chiyero chekuchengetedza chemuenzaniso wekuita chinovandudzwa zvakanyanya. Kana iyo inoshanda zinc oxide inoshandiswa muhuwandu hwakaderedzwa, TC90 - TS1 inopfupisa, ML uye MH shanduko haina kukosha, uye mechanical properties ye vulcanized rubber shanduko haisi pachena; 2.5 zvikamu zvedosi, kuchembera kwerabha yakasvibiswa kunoderera, saka huwandu hunogona kudzikiswa kusvika kuzvikamu zvitatu zvedosi inoshandiswa.
Zvakanakira zinc oxide
Kuburikidza nedhata rekuyedza rezvigadzirwa zviri pamusoro, zvinogona kudzidzwa kuti inoshanda zinc oxide inogona kushandiswa zvakanyanya mumhando dzakasiyana dzerubha zvigadzirwa.
(1) Iine kupararira kwakanaka mune yerubha zvinhu, uye zvemuviri uye zvemuchina zvivakwa zvinovandudzwa;
(2) Mukuita vulcanization. Nguva yekubika yerubha zvinhu inova yakareba, kuchengetedzwa kwevulcanization kunovandudzwa, uye kushanda kwevulcanization kunovandudzwa;
(3) Nekuda kweiyo yakakura chaiyo nzvimbo uye diki saizi yeinoshanda zinc oxide, inogona kushandiswa muhuwandu hwakadzikiswa mukuwedzera kwezvimwe zvinhu zverabha.
