Zinc oxyde nikintu gikoreshwa cyane mugutunganya reberi. Mu musaruro wa reberi, imyanda nogutunganya ibintu birashobora kurekura ibice bya zinc, bigatera kwangiza ibidukikije, bityo ingano ya okiside ya zinc muri formulaire ya reberi igomba kugabanuka. okiside ikora ya zinc ifite ingano ntoya, ubuso bunini bwubuso, ibikorwa byinshi by’ibirunga, ugereranije na okiside isanzwe ya zinc, ingano ya okiside ya zinc iragabanuka , bityo bikagabanya ingaruka zinc ku bidukikije, bikagaragaza inyungu z’ibidukikije n’ubukungu.
Ctive oxyde zinc oxyde ikorwa hifashishijwe uburyo butose, guhuza imvura no gutwika, kugirango bibyare umusaruro wa zinc na okiside ya zinc mu mucyo, bitandukanye nuburyo busanzwe bwo kubara butaziguye bukoreshwa nabandi bakora ibicuruzwa byinshi. Igikorwa gitose gifite urwego rwo hejuru ruhoraho mubwiza, inzira nayo itanga ubuso bunini bwihariye (40m2 / g) hamwe nubunini bwiza bwo gukwirakwiza kubintu byinshi, kandi ibintu bike byanduye byibyuma biremereye nikimwe mubidukikije byangiza ibidukikije.
Igikorwa cyo kubyaza umusaruro amazi yatose nuburyo bukurikira: inginc ingot na acide sulfurique reaction yo kubyara zinc sulfate, hanyuma reaction yayo hamwe na sodium karubone kugirango itange karubone ya zinc nkibikoresho fatizo bya okiside ya zinc. Hamwe na karubone ya zinc nkibikoresho fatizo, okiside ya zinc ikorwa no gukaraba, kumisha, kubara no kumenagura.
Impuzandengo y'ibice bya oxyde ya zinc ikora ni 50nm, ubuso bwihariye ni bunini, hafi 40m2 / g, na kristu ni ubuki, bworoshye kandi bworoshye, bityo gutatanya ni byiza; umuvuduko wacyo wo kwihuta biruta okiside ya zinc isanzwe, gukwirakwiza ni kimwe, mubitekerezo byo kunoza ibintu byo guhuza ibiraro, ahanini birashobora kwitabwaho rwose; ibyuma biremereye Pb2 +, Cu2 +, Cd2 +, Mn2 +, Fe2 + ibirimo biri hasi cyane, bijyanye nibisabwa kurengera ibidukikije.
Gukoresha ibicuruzwa
Zinc oxyde mu nganda zikoreshwa cyane cyane nka rubber vulcanisation ikora (agent yihuta), umurimo wacyo ni ukuzamura imikorere yihuta yihuta no kunoza ingaruka ziterwa na rubber. Uburyo bwo kubyitwaramo ni: okiside ya zinc na yihuta ya chimique kubyara umunyu wa zinc yihuta; umuvuduko wa zinc umunyu na molekile ya polysulfide kugirango ubyare umunyu wa polysulfide; polysulfide zinc umunyu na rubber macromolecule reaction kugirango irangize imiti ya nyuma ihuza imiti, kugirango iteze imbere kwanduza reberi, gukora no gushimangira uruhare rwo kurwanya gusaza, kugirango habeho ituze, umutekano utunganyirizwa, kugabanuka kwinshi kugipimo cy’inenge, no kuzamura ibicuruzwa bya reberi, kurwanya amarira, kurwanya abrasion, no kongera kurambura kwa rubber. Kandi utezimbere reberi irambuye irambuye, imbaraga zingana no kuramba, kugabanya compression ihoraho, nibindi.
1. Okiside ya zinc ikora muri kimwe cya kabiri cyuma ya radiyo ipine yimbere
Muburyo bumwe, ikoreshwa rya zinc oxyde ikora 2 # formula ya rubber ikiza umuvuduko kuruta gukoresha okiside ya zinc isanzwe 1 # reberi ya formula yiyongereyeho inshuro 1; 3 # formula ya dosiye ikora ya zinc oxyde ni 1 # gusa ya formula ya zinc oxyde isanzwe ya 80%, ariko umuvuduko wa 3 # formula yo gukiza iracyihuta cyane kuruta formula ya rubber l. 3 formulaire ya rubber coking, menni viscosity ntabwo itandukanye cyane.
Ikizamini cya formula ya volcanized rubber ubukana, guhora uhangayitse, imbaraga zamarira nimbaraga zamarira kuruta formulaire yumusemburo wa vulcanized reberi yateye imbere, kurwanya umunaniro nurwego rwimikorere iragereranywa, ubushyuhe nubusaza bwumwuka byagabanutseho gato.
okiside ya zinc ikora aho kuba okiside isanzwe ya zinc ikoreshwa muri kimwe cya kabiri cyuma cya radial tine imbere ply reberi, gukiza imiterere yumubiri wa reberi no gukoresha urwego rusanzwe rwa zinc oxyde ya reberi igereranywa nubwa reberi, umuvuduko w’ibirunga byihuta, bikaba bifasha kugabanya igihe cy’ibirunga. Gukoresha okiside ya zinc iko

Hamwe no kwiyongera kwinshi kwa zinc oxyde ikora, TC10 na TC90 muri rusange inzira yo gukura. ML na MH ntabwo byahinduye byinshi. Ibi bivuze ko okiside ya zinc ikora irashobora gukoreshwa mukigero gito.
Imbaraga zingana, kurambura 100%, kurambura 300% no kurira kwa reberi ntabwo byahindutse cyane hamwe no kwiyongera kwinshi kwa okiside ya zinc ikora. Iyo igipimo kirenze ibice 5, imbaraga zo kurira za reberi yibirunga igabanya inst ead, iterwa no kwiyongera gukabije kwinshi. Nyuma yo gusaza kuri 100 ℃ × 24h, igipimo cyo kugumana imikorere ya reberi hamwe nibice 3 bya okiside ya zinc oxyde nibyiza, kandi ko hamwe nibice 2,5 bya dosiye aribyo bibi cyane. Impamvu irashobora kuba ingano yibice 2,5, imiterere ya rubber mesh yubatswe ntago itunganye, ibyo bikagaragarira no kurambura kimwe kurira, guhindagurika burundu kurira, gukomera kwinkombe, no gukora ubushyuhe bwo kubyara ubushyuhe.
Kwiyongera kwa zinc oxide rubber ivanze, TC10 na TC90 birebire cyane, torque ntoya ML, itara ryinshi Mn hamwe n’itandukaniro riri hagati ya MH ebyiri ML yiyongera, byerekana ko umutekano wacyo wo gutunganya, umuvuduko w’ibirindiro wihuta, urwego rwo guhuza imbaraga rwiyongereye, imbaraga zayo zingana, 100% kuramba byateganijwe no gusaza byaragabanutse, 100 24h ℃ , igipimo cyo kugumana imikorere yikigereranyo cyateye imbere cyane. Iyo okiside ikora ya zinc ikoreshwa mukugabanuka kwinshi, TC90 - TS1 igabanya, ML na MH impinduka ntizihambaye, kandi imiterere yubukanishi bwimpinduka za rubber ntizigaragara; Ibice 2,5 bya dosiye, kurwanya gusaza kwa reberi yibirunga bigabanuka, bityo amafaranga arashobora kugabanuka kugeza kubice 3 bya dosiye igomba gukoreshwa.
Ibyiza bya okiside ya zinc
Binyuze mu bushakashatsi bwibicuruzwa byavuzwe haruguru, birashobora kumenyekana ko okiside ya zinc ikora ishobora gukoreshwa cyane mubicuruzwa bitandukanye bya reberi.
(1) Ifite ikwirakwizwa ryiza mubikoresho bya reberi, kandi imiterere yumubiri nubukanishi iratera imbere;
(2) Mubikorwa byo kurunga. Igihe cyo gukata cyibikoresho bya reberi kiba kirekire, umutekano w’ibirunga uratera imbere, kandi imikorere y’ibirunga ikanozwa;
