ʻO Zinc oxide kahi mea hana maʻamau i hoʻohana ʻia i ka hana ʻana i ka lāʻau. I ka hana ʻana i ka lāʻau lapaʻau, hiki ke hoʻokuʻu ʻia ka ʻōpala a me ke kaʻina hana hou i nā pūhui zinc, e hōʻeha ai i ke kaiapuni, no laila pono e hoʻemi ʻia ka nui o ka zinc oxide i loko o ke kumu lāʻau. ʻO ka zinc oxide ka mea liʻiliʻi liʻiliʻi, ka nui o ka ʻili, ka hana vulcanization kiʻekiʻe, ke hoʻohālikelike ʻia me ka zinc oxide , ua hoʻemi ʻia ka nui o maʻamau ka zinc oxide, no laila e hōʻemi ana i ka pōʻino o ka zinc i ke kaiapuni, e hōʻike ana i nā pono o ke kaiapuni a me ka waiwai.
kahi zinc oxide me ka hoʻohana ʻana i kahi kaʻina wai, ka hui pū ʻana o ka ua a me ka ʻai ʻana, e hana Hana ʻia ai i ka zinc oxide a me ka zinc oxide transparent, e kū'ē ana i ke kaʻina hana calcination kuʻuna i hoʻohana ʻia e nā mea hana ʻē aʻe. He kūlana kiʻekiʻe ke kaʻina hana maʻemaʻe i ka maikaʻi, ʻo ke kaʻina hana pū kekahi i kahi kikoʻī kikoʻī kikoʻī nui (40m2 / g) a me ka hāʻawi ʻana i ka nui o nā mea nui no nā noi he nui, a ʻo ka haʻahaʻa haʻahaʻa o nā haumia metala kaumaha kekahi o nā hōʻoia kūlohelohe o kēia huahana.
ʻO ke kaʻina hana o ke kaʻina wai penei: zinc ingot a me sulfuric acid pane e hoʻohua i ka zinc sulfate, a laila kāna pane me ka sodium carbonate e hana i ka zinc carbonate i mea maka no ka zinc oxide. Me ka zinc carbonate e like me ka mea maka, hana ʻia ka zinc oxide ma ka holoi ʻana, hoʻomaloʻo, calcining a me ka ʻoki ʻana.
ʻO ka awelika o ka nui o ka zinc oxide he 50nm, nui ka ʻāpana kikoʻī, e pili ana i 40m2 / g, a ʻo nā kristal he honeycomb, wehe a porous, no laila maikaʻi ka hoʻopuehu; ʻOi aku ka wikiwiki o kona diffusion ma mua o ka zinc oxide maʻamau, ʻokoʻa ka hāʻawi ʻana, i ka hopena e hoʻomaikaʻi ai i ke ʻano o ka hoʻohuihui ʻana, hiki ke hoʻokō piha ʻia; nā metala kaumaha Pb2 +, Cu2 +, Cd2 +, Mn2 +, Fe2 + maʻiʻo haʻahaʻa loa, e like me nā koi o ka mālama ʻana i ke kaiapuni.
Hoʻohana Huahana
Hoʻohana nui ʻia ʻo Zinc oxide i loko o ka ʻoihana pahū e like me ka vulcanization active agent (accelerating agent), ʻo ia ka hana e hoʻonui ai i ka hoʻoulu ʻana o ka vulcanization accelerator a hoʻomaikaʻi i ka hopena vulcanization o ka lāʻau. ʻO kona ʻano hana: zinc oxide a me ka hopena kemika accelerator e hana i ka paʻakai zinc accelerator; ʻO ka paʻakai zinc accelerator a me nā molekole polysulfide e hana i ka paʻakai zinc polysulfide; polysulfide zinc salt a me rubber macromolecule reaction e hoʻopau ai i ka crosslinking kemikala hope loa, i mea e hoʻoikaika ai i ka vulcanization o ka lāʻau, hoʻoikaika a me ka hoʻoikaika ʻana i ka hana o ka anti-aging, e hoʻokō i ka paʻa, ka palekana o ka hana, ka nui o ka hoʻemi ʻana i ka helu kīnā, a me ka hoʻomaikaʻi ʻana i nā huahana, nā waimaka kūʻē, kūʻē abrasion, a hoʻonui i ka elongation paʻa o ka vulcan. A hoʻomaikaʻi i ka vulcanized rubber stretch stress, tensile strength and elongation, hōʻemi i ka hoʻoemi mau ʻana i ka deformation, etc.
1. Hoʻoikaika zinc oxide i loko o ka hoʻohana ʻana i ka pahu radial semi-steel innerliner
I ka nui o nā kūlana, hoʻonui ka hoʻohana ʻana i ka zinc oxide 2 # formula rubber curing speed ma mua o ka hoʻohana ʻana i ka zinc oxide 1 # formula rubber ma kahi o 1 mau manawa; ʻO ka 3 # kumu o ka hana zinc oxide ikaika ʻo 1 wale nō ka ʻano o ka zinc oxide maʻamau o 80%, akā ʻoi aku ka wikiwiki o ka 3 # formula rubber curing speed ma mua o ke kumu o ka rubber l. ʻO 3 mau ʻano o nā waiwai coking rubber, ʻaʻole ʻokoʻa ka Menni viscosity.
