Chidule cha Oxalic Acid
Oxalic acid, yomwe imadziwikanso kuti ethanedioic acid, ndi dicarboxylic acid yosavuta kwambiri yokhala ndi molecular formula (COOH) 2 ⋅2H2O
Imawoneka ngati makristalo opanda mtundu ndipo ndi gawo lofala mu zomera za herbaceous, makamaka zomwe zimapezeka mu mawonekedwe a mchere wa potaziyamu kapena calcium, pomwe imapezeka ngati asidi waulere m'zomera monga Chinese crabapple ndi nthochi. Oxalic acid yochepa imapezekanso mu mkodzo wa anthu, ndipo calcium oxalate ndiye gawo lalikulu la miyala ya mkodzo. Ikatenthedwa kufika pa 100.1 °C, makristalo a oxalic acid amataya madzi awo opangidwa ndi crystallization ndikupanga anhydrous oxalic acid, yomwe ili ndi malo osungunuka a 189.5 °C. Anhydrous oxalic acid imasungunuka m'madzi kapena ethanol koma sisungunuka mu ether. Mu labotale, oxalic acid imatha kusungunuka ndi kutentha kuti ipange mpweya wa carbon monoxide.
Oxalic acid ndi mankhwala ofunikira kwambiri omwe amagwiritsidwa ntchito m'njira zosiyanasiyana ndipo amagwiritsidwa ntchito m'magawo ambiri. Ndi chitukuko cha mafakitale opanga mankhwala, utoto, ndi zokutira komanso kutsegulidwa kwa msika wapadziko lonse lapansi, ndikofunikira kwambiri kufufuza ndikupanga kupanga oxalic acid.

Shandong Pulisi Chemical Co., Ltd. - Mbiri ya Oxalic Acid
Shandong Pulisi Chemical Co., Ltd., yomwe idakhazikitsidwa mu Okutobala 2006 ndipo likulu lake lili ku Zibo, Shandong, ndi kampani yotsogola yopereka zinthu zopangira mankhwala apamwamba kwambiri padziko lonse lapansi. Podzipereka ku filosofi ya "kuyang'ana kwambiri pakupanga mankhwala abwino", kampaniyo yasintha kukhala bizinesi yophatikiza kafukufuku ndi chitukuko, kupanga, malonda ndi zinthu zoyendera, ndi mabungwe ogwirizana nawo kuphatikiza Zibo Anhao Chemical Co., Ltd. ndi China Changrui Co., Limited.
Asidi wathu wa oxalic (CAS No.: 144-62-7 wa anhydrous, 6153-56-6 wa dihydrate) ndi chinthu chachikulu, chopangidwa kuti chikwaniritse miyezo yapadziko lonse lapansi. Imapezeka mu mtundu wa mafakitale (purity ≥96%) ndi mtundu woyengedwa (purity ≥99.6%), asidi wathu wa oxalic ulipo ngati makhiristo owonekera opanda mtundu (nthawi zambiri dihydrate) okhala ndi formula ya molekyulu C₂H₂O₄·2H₂O ndi kulemera kwa molekyulu ya 126.07. Ili ndi kusungunuka kwakukulu m'madzi ndi ethanol, mphamvu zochepetsera, komanso acidity yambiri - zomwe zimapangitsa kuti ikhale imodzi mwa ma dicarboxylic acid amphamvu kwambiri.
Popeza timayang'aniridwa bwino kwambiri kuti titsatire miyezo ya ISO 9001:2015 komanso kuvomerezedwa ndi mabungwe ovomerezeka monga German BV, oxalic acid yathu imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana:
Metallurgy: Kuchotsa dzimbiri bwino, kuyeretsa zitsulo ndi kupangitsa kuti chitsulo, mkuwa ndi zitsulo zina zisamaume bwino.
Kapangidwe: Zipangizo zofunika kwambiri zopangira konkriti ndi kukonza zipangizo zomangira.
Makampani opanga zikopa: Amagwiritsidwa ntchito poyeretsa, kuchotsa mafuta ndi kupukuta khungu la chikopa.
Kuchiza madzi: Chothandizira kuchotsa madzi m'madzi kuti achepetse kuipitsidwa kwa madzi komanso kuchotsa mamba.
Nsalu ndi kusindikiza: Wothandizira kuyeretsa ndi kupaka utoto.
Makampani opanga mankhwala ndi chakudya: Amagwiritsidwa ntchito popanga zinthu zopangira mankhwala komanso kukonza zowonjezera chakudya.
Ndi malo osungiramo katundu odziyimira pawokha ku Qingdao, Tianjin, Shanghai ports ndi Zibo Free Trade Zone, timaonetsetsa kuti makasitomala athu atumizidwa bwino padziko lonse lapansi. Zogulitsa zathu zadutsa ziphaso za REACH, FAMI-QS ndi SGS, ndipo zimatumizidwa kumayiko ndi madera opitilira 100 ku Europe, America, Southeast Asia, Middle East ndi Central Asia. Takhazikitsa ubale wolimba wa nthawi yayitali ndi makampani otchuka kuphatikiza PetroChina, CNOOC, Saint-Gobain ndi Lafarge.
Ku Shandong Pulisi Chemical, timaika patsogolo ntchito yabwino, chitetezo komanso yoyang'ana kwambiri makasitomala, kupereka mayankho a oxalic acid omwe amakonzedwa mwamakonda kuti akwaniritse zosowa zosiyanasiyana zamafakitale padziko lonse lapansi.
