Miyezo Yabwino ya Oxalic Acid (National Standard)
Oxalic acid, yomwe imadziwikanso kuti ethanedioic acid, ili ndi kapangidwe kake ka HOOCCOOH ndi kulemera kwa molar kwa 126.07. Nthawi zambiri imakhala ngati dihydrate, yomwe imawoneka ngati makristalo opanda mtundu kapena ufa woyera, yopanda fungo komanso kukoma kowawasa. Ili ndi mitundu iwiri ya makristalo: mawonekedwe a α (rhombic) ndi mawonekedwe a β (monoclinic). Malo awo osungunuka ndi kuchulukana kwawo (pa 17°C/4°C) ndi awa: mawonekedwe a α pa 189.5°C yokhala ndi kachulukidwe ka 1.900; mawonekedwe a β pa 182°C yokhala ndi kachulukidwe ka 1.895. Ikakumana ndi mpweya wouma kapena kutentha, imataya madzi ake ophimbidwa. Oxalic acid ndi yosinthasintha ndipo imasungunuka mosavuta: imayamba kusungunuka pa 100°C, imasungunuka mwachangu pa 125°C, ndipo imasungunuka kwambiri ikamayamba kuwola pa 157°C. Imasungunuka m'madzi otentha ndi ethanol, imasungunuka pang'ono m'madzi ozizira, imasungunuka pang'ono mu diethyl ether, ndipo siisungunuka mu benzene ndi chloroform. Monga asidi wamphamvu wachilengedwe, oxalic acid imakumana ndi zotsatira za neutralization ndi maziko.

Kugwiritsa Ntchito Oxalic Acid
Oxalic acid imagwiritsidwa ntchito kwambiri pochotsa dzimbiri, kuyeretsa, kusindikiza ndi kuyika utoto pa nsalu, komanso kuyeretsa nyumba. Imathandizanso popanga zinthu zoyambitsa cobalt-molybdenum-aluminium, kuyeretsa zitsulo ndi miyala ya marble, komanso kuyeretsa nsalu. Kuphatikiza apo, oxalic acid imagwira ntchito ngati mankhwala ophera mabakiteriya pakamwa pa nyama, omwe amagwiritsidwa ntchito pochiza matenda a chakudya.
Zibo Anhao Chemical Co., Ltd. – Oxalic Acid
Zibo Anhao Chemical Co., Ltd. ndi kampani yogulitsa mankhwala a oxalic acid (ethanedioic acid, C₂H₂O₄·2H₂O) yomwe ili ku Shandong, China. Oxalic acid yathu imapangidwa motsatira malamulo okhwima, imawoneka ngati makhiristo owonekera opanda mtundu kapena ufa woyera, ndi chiyero cha ≥99.0%. Ili ndi asidi wambiri, mphamvu zabwino zochepetsera madzi komanso kusungunuka bwino kwa madzi, zomwe zimapangitsa kuti ikhale mankhwala ogwiritsidwa ntchito m'mafakitale osiyanasiyana.
Oxalic acid yathu imagwiritsidwa ntchito kwambiri ngati chochepetsera, choyeretsera utoto, komanso choyeretsera utoto m'mafakitale osiyanasiyana. Pakuyika utoto pa nsalu, imawonjezera kuwala kwa mtundu komanso kufulumira kwa utoto. Pakukonza zitsulo, imachotsa bwino dzimbiri ndi mamba kuchokera ku chitsulo ndi ma alloys. Imagwira ntchito ngati chinthu chofunikira kwambiri popanga mankhwala, kuchotsa nthaka yosowa, kupukuta khungu, komanso kuyeretsa madzi. Kuphatikiza apo, imagwiritsidwa ntchito kwambiri pazinthu zotsukira pochotsa madontho ndi mchere.
Ku Zibo Anhao Chemical, timaika patsogolo khalidwe lokhazikika, kupereka kodalirika komanso mitengo yopikisana. Ndi zipangizo zamakono zopangira komanso chidziwitso chambiri chotumiza kunja, timaonetsetsa kuti oxalic acid yathu ikukwaniritsa miyezo yapadziko lonse lapansi komanso zofunikira za makasitomala padziko lonse lapansi. Timaperekanso ma phukusi okonzedwa mwamakonda (matumba 25kg) komanso chithandizo chaukadaulo chaukadaulo kuti tithandizire ntchito zosiyanasiyana zamafakitale.
Sankhani Zibo Anhao Chemical ya oxalic acid yoyera kwambiri yomwe imapereka magwiridwe antchito okhazikika komanso phindu ku bizinesi yanu. Lumikizanani nafe kuti mupeze maoda ambiri kapena zidziwitso zaukadaulo: info@anhaochemical.com
