Isishwankathelo seMveliso ye-Oxalic Acid
I-oxalic acid, ekwaziwa ngokuba yi-ethanedioic acid, yeyona dicarboxylic acid ilula ene-molecular formula (COOH) 2 ⋅2H2O
Ibonakala njengeekristale ezingenambala zekholamu kwaye iyinxalenye eqhelekileyo kwizityalo ezifuywayo, uninzi lwazo lufumaneka kwisimo se-potassium okanye i-calcium salts, ngelixa ifumaneka njenge-free acid kwizityalo ezifana ne-Chinese crabapple kunye ne-banana. Inani elincinci le-oxalic acid likwakho kumchamo womntu, kwaye i-calcium oxalate yeyona nto iphambili yamatye omchamo. Xa ishushu ukuya kwi-100.1 °C, iikristale ze-oxalic acid zilahlekelwa ngamanzi azo e-crystallization ukuze zenze i-anhydrous oxalic acid, enendawo yokunyibilika eyi-189.5 °C. I-anhydrous oxalic acid iyanyibilika emanzini okanye kwi-ethanol kodwa ayinyibiliki kwi-ether. Kwilabhoratri, i-oxalic acid inokunyibilika ngobushushu ukuze kuveliswe igesi ye-carbon monoxide.
I-oxalic acid sisixhobo esibalulekileyo sekhemikhali esisetyenziswa ngeendlela ezahlukeneyo kwaye sisetyenziswa kwiindawo ezininzi. Ngokuphuhliswa kwamashishini amayeza, idayi, kunye nokufaka i-coating kunye nokuvulwa kwemarike yamazwe ngamazwe, kuyimfuneko kakhulu ukuphanda nokuphuhlisa imveliso ye-oxalic acid.

I-Shandong Pulisi Chemical Co., Ltd. – Iprofayili ye-Oxalic Acid
I-Shandong Pulisi Chemical Co., Ltd., eyasekwa ngo-Okthobha ka-2006 kwaye inekomkhulu eZibo, eShandong, ngumthengisi ophambili wobuchwephesha wezinto ezikrwada zeekhemikhali ezikumgangatho ophezulu ezineempawu zehlabathi. Izinikele kwifilosofi "yokugxila kuphuhliso lweekhemikhali ezisemgangathweni", inkampani iguqukele ekubeni lishishini elibanzi elidibanisa uR&D, imveliso, ukuthengisa kunye nothutho, kunye namaziko anxulumeneyo kuquka iZibo Anhao Chemical Co., Ltd. kunye neChina Changrui Co., Limited.
I-asidi yethu ye-oxalic (iNombolo ye-CAS: 144-62-7 ye-anhydrous, 6153-56-6 ye-dihydrate) yimveliso ephambili, eyenziwe ukuhlangabezana nemigangatho yomgangatho wamazwe ngamazwe. Ifumaneka kudidi lwemizi-mveliso (ubumsulwa ≥96%) kunye nodidi olucociweyo (ubumsulwa ≥99.6%), i-asidi yethu ye-oxalic ikhona njengeekristale ezicacileyo ezingenambala (ngesiqhelo i-dihydrate) ngefomula yemolekyuli C₂H₂O₄·2H₂O kunye nobunzima bemolekyuli obuyi-126.07. Inokunyibilika okuphezulu emanzini nakwi-ethanol, iipropati zokunciphisa ezinamandla, kunye ne-asidi ephezulu-okuyenza ibe yenye yezona asidi ze-dicarboxylic ezinamandla kakhulu.
I-oxalic acid yethu ilawulwa ngononophelo ukuze ihambelane nemigangatho ye-ISO 9001:2015 kwaye iqinisekiswe ziinkampani ezigunyazisiweyo ezifana ne-German BV, i-oxalic acid yethu isetyenziswa kakhulu kumashishini amaninzi:
I-Metallurgy: Ukususa umhlwa ngempumelelo, ukucoca isinyithi kunye ne-complexation yesinyithi, ubhedu kunye nezinye izinyithi.
Ulwakhiwo: Izinto ezibalulekileyo zokuxuba izinto zekhonkrithi kunye nokulungiswa kwezinto zokwakha.
Ishishini lesikhumba: Lisetyenziselwa ukumhlopheza, ukususa amafutha kunye nokuthambisa isikhumba.
Unyango lwamanzi: Isixhobo sokucoca amanzi ukuze kuphuculwe umgangatho wamanzi kwaye kususwe isikali.
Impahla yokunxiba kunye nokuprinta: Iarhente yokufunxa kunye neyokudaya.
Amashishini oNyango nokutya: Asetyenziswa ekuhlanganiseni izinto ezidityanisiweyo zamayeza kunye nokulungiswa kwezongezo zokutya.
Njengoko sineendawo zokugcina impahla ezizimeleyo eQingdao, eTianjin, eShanghai nakwiZibo Free Trade Zone, siqinisekisa ukuhanjiswa okusebenzayo kubathengi behlabathi. Iimveliso zethu ziphumelele iziqinisekiso ze-REACH, FAMI-QS kunye ne-SGS, kwaye zithunyelwa kumazwe angaphezu kwe-100 kunye nemimandla eYurophu, eMelika, eMzantsi-mpuma Asia, eMbindi Mpuma nakwiMbindi Asia. Siseke ubudlelwane obuzinzileyo bentsebenziswano obuhlala ixesha elide namashishini adumileyo aquka iPetroChina, iCNOOC, iSaint-Gobain kunye neLafarge.
Apha eShandong Pulisi Chemical, sibeka phambili umgangatho, ukhuseleko kunye nenkonzo egxile kubathengi, sinikezela ngezisombululo ze-oxalic acid ezenzelwe wena ukuhlangabezana neemfuno ezahlukeneyo zoshishino kwihlabathi liphela.
