Opanga awiri akuluakulu a antimony trioxide padziko lonse lapansi asiya kupanga. Akatswiri amakampani adafufuza kuti kuyimitsidwa kwa kupanga ndi opanga awiri akuluakulu kudzakhudza mwachindunji kupezeka kwa msika wa antimony trioxide mtsogolo. Monga kampani yodziwika bwino yopanga ndi kutumiza kunja kwa antimony oxide ku China, UrbanMines Tech. Co., Ltd. imasamala kwambiri za chidziwitso chamakampani apadziko lonse lapansi cha zinthu za antimony oxide.
Kodi antimony oxide ndi chiyani kwenikweni? Kodi pali ubale wotani pakati pa kugwiritsidwa ntchito kwake kwakukulu ndi ntchito zopangira mafakitale? Pali zomwe zapezeka mu kafukufuku monga momwe zilili pansipa kuchokera ku gulu la Technology Research and Development Department of UrbanMines Tech. Co., Ltd.
Antimoni okusayidiNdi mankhwala opangidwa m'gulu la mitundu iwiri: antimony trioxide Sb2O3 ndi antimony pentoxide Sb2O5. Antimony trioxide ndi kristalo woyera wa cubic, wosungunuka mu hydrochloric acid ndi tartaric acid, wosasungunuka m'madzi ndi acetic acid. Antimony pentoxide ndi ufa wachikasu wopepuka, wosasungunuka m'madzi, wosungunuka pang'ono mu alkali, ndipo ukhoza kupanga antimonate.
Kodi ntchito ya zinthu ziwirizi ndi yotani pa moyo?
Choyamba, zingagwiritsidwe ntchito ngati zophimba moto ndi zoletsa moto. Antimony trioxide imatha kuzimitsa malawi, kotero nthawi zambiri imagwiritsidwa ntchito ngati zophimba moto m'moyo watsiku ndi tsiku. Kachiwiri, antimony trioxide imagwiritsidwa ntchito ngati zoletsa moto kuyambira zaka zoyambirira. Poyamba kuyaka, imasungunuka isanayambe chinthu china, kenako filimu yoteteza imapangidwa pamwamba pa chinthucho kuti ichotse mpweya. Pa kutentha kwakukulu, antimony trioxide imapangidwa ndi mpweya ndipo kuchuluka kwa mpweya kumachepa. Antimony trioxide imagwira ntchito poletsa moto.
Zonse ziwiriantimoni trioxidendiantimoni pentoxidendi zowonjezera zoletsa moto, kotero mphamvu ya moto imakhala yofooka ikagwiritsidwa ntchito yokha, ndipo mlingo wake uyenera kukhala waukulu. Nthawi zambiri imagwiritsidwa ntchito limodzi ndi zinthu zina zoletsa moto ndi zoletsa utsi. Antimony trioxide nthawi zambiri imagwiritsidwa ntchito limodzi ndi zinthu zachilengedwe zokhala ndi halogen. Antimony pentoxide nthawi zambiri imagwiritsidwa ntchito limodzi ndi organic chlorine ndi bromine type flame retardants, ndipo zotsatira zake zimatha kupangidwa pakati pa zigawozo, zomwe zimapangitsa kuti mphamvu ya moto ikhale yabwino.
Hydrosol ya antimony pentoxide imatha kufalikira mofanana komanso mokhazikika mu slurry ya nsalu, ndikufalikira mkati mwa ulusi ngati tinthu tating'onoting'ono kwambiri, tomwe ndi oyenera kupota ulusi woletsa moto. Ingagwiritsidwenso ntchito pomaliza nsalu zomwe zimaletsa moto. Nsalu zomwe zimatsukidwa nazo zimakhala ndi kutsuka kolimba kwambiri, ndipo sizikhudza mtundu wa nsalu, kotero zotsatira zake zimakhala zabwino kwambiri.
Mayiko otukuka mafakitale monga United States adafufuza ndikukulitsacolloidal antimoni pentoxideZosapangidwa m'chilengedwe kumapeto kwa zaka za m'ma 1970. Kuyesera kwatsimikizira kuti kuletsa kwake moto ndi kwakukulu kuposa kwa antimony pentoxide ndi antimony trioxide yosakhala ya colloidal. Ndi antimony-based lawi retardant. Imodzi mwa mitundu yabwino kwambiri. Ili ndi mphamvu yochepa yopaka utoto, kukhazikika kwa kutentha kwambiri, kutulutsa utsi pang'ono, kosavuta kuwonjezera, kosavuta kufalitsa, komanso mtengo wotsika. Pakadali pano, antimony oxide yagwiritsidwa ntchito kwambiri ngati choletsa moto m'mapulasitiki, rabara, nsalu, ulusi wa mankhwala, zamagetsi ndi mafakitale ena.
Kachiwiri, imagwiritsidwa ntchito ngati utoto ndi utoto. Antimony trioxide ndi utoto woyera wosapangidwa ndi zinthu zachilengedwe, womwe umagwiritsidwa ntchito makamaka mu utoto ndi mafakitale ena, popanga mordant, chophimba zinthu zopangidwa ndi enamel ndi ceramic, choyera, ndi zina zotero. Chingagwiritsidwe ntchito ngati kulekanitsa mankhwala ndi mowa. Chimagwiritsidwanso ntchito popanga antimones, antimony compounds ndi makampani opanga mankhwala.
Pomaliza, kuwonjezera pa kugwiritsa ntchito mankhwala oletsa moto, antimony pentoxide hydrosol ingagwiritsidwenso ntchito ngati mankhwala ochizira pamwamba pa pulasitiki ndi zitsulo, zomwe zingathandize kulimbitsa chitsulo ndi kukana kuwonongeka, ndikuwonjezera kukana dzimbiri.
Mwachidule, antimoni trioxide yakhala chinthu chofunikira kwambiri m'mafakitale ambiri.
