Nthawi zambiri timakupatsirani ntchito zabwino kwambiri kwa ogula, komanso mitundu yosiyanasiyana ya mapangidwe ndi masitaelo okhala ndi zipangizo zabwino kwambiri. Ntchito izi zikuphatikizapo kupezeka kwa mapangidwe okonzedwa mwachangu komanso kutumiza kwa Factory Selling Factory Wholesale Rust Removal Industrial Grade Oxalic Acid H2c2o4 CAS 6153-56-6, Mwachidule, mukasankha ife, mumasankha moyo wangwiro. Takulandirani ku fakitale yathu ndikulandila oda yanu! Kuti mudziwe zambiri, chonde musazengereze kulumikizana nafe.
Nthawi zambiri timakupatsirani ntchito zabwino kwambiri kwa ogula, komanso mitundu yosiyanasiyana ya mapangidwe ndi masitayelo okhala ndi zipangizo zabwino kwambiri. Ntchito izi zikuphatikizapo kupezeka kwa mapangidwe okonzedwa mwachangu komanso otumizidwa. Timaperekanso ntchito ya OEM yomwe imakwaniritsa zosowa zanu. Ndi gulu lamphamvu la mainjiniya odziwa bwino ntchito yopanga ndi kupanga ma payipi, timayamikira mwayi uliwonse wopereka zinthu zabwino kwambiri kwa makasitomala athu.

Mafunso Ofunsidwa Kawirikawiri

Mukufuna thandizo? Onetsetsani kuti mwapita ku malo athu othandizira kuti mupeze mayankho a mafunso anu!

Kodi tingasindikize chizindikiro chathu pa chinthucho?

Inde, tikhoza kuchita. Ingotitumizirani kapangidwe ka logo yanu.

Kodi mumalandira maoda ang'onoang'ono?

Inde. Ngati ndinu wogulitsa pang'ono kapena bizinesi yoyambira, ndife okonzeka kukula nanu. Ndipo tikuyembekezera kugwira nanu ntchito limodzi kwa nthawi yayitali.

Nanga mtengo wake ndi wotani? Kodi mungaupange kukhala wotsika mtengo?

Nthawi zonse timaona ubwino wa kasitomala kukhala chinthu chofunika kwambiri. Mtengo ungathe kukambidwa pazifukwa zosiyanasiyana, tikukutsimikizirani kuti mupeza mtengo wopikisana kwambiri.

Kodi mumapereka zitsanzo zaulere?

Ndife okondwa kuti mutha kutilembera ndemanga zabwino ngati mumakonda zinthu ndi ntchito zathu, tidzakupatsani zitsanzo zaulere pa oda yanu yotsatira.

Kodi mumatha kupereka zinthu pa nthawi yake?

Zachidziwikire! Takhala akatswiri pa mzerewu kwa zaka zambiri, makasitomala ambiri amapanga mgwirizano ndi ine chifukwa timatha kutumiza katunduyo pa nthawi yake ndikusunga katunduyo ali wabwino kwambiri!

Kodi ndingapite ku kampani yanu ndi fakitale yanu ku China?

Inde. Mwalandiridwa kwambiri kuti mudzacheze kampani yathu ku Zibo, China. (1.5hr kuchokera ku Jinan)

Kodi ndingayitanitse bwanji oda?

Mungotumiza mafunso kwa aliyense wa ogulitsa athu kuti mudziwe zambiri zokhudza oda, ndipo tidzafotokoza mwatsatanetsatane momwe zinthu zilili. 2.3 Njira ya Sodium Formate
Kupanga kwa oxalic acid pogwiritsa ntchito njira ya sodium formate kumagawidwa m'magulu awiri: njira ya lead ndi njira ya calcium. Carbon monoxide imatengedwa ndi yankho la sodium hydroxide kuti ipange sodium formate, yomwe kenako imachotsedwa mu hydrogen kuti ipange sodium oxalate. Yotsirizirayi imayanjana ndi lead sulfate (njira ya lead) kapena calcium hydroxide (njira ya calcium) kuti ipange lead oxalate precipitate kapena calcium oxalate precipitate, yomwe kenako imaphatikizidwa ndi sulfuric acid kuti ipange oxalic acid.
Njira yopangira asidi wa oxalic: Pambuyo potsuka, kutsuka ndi alkali, ndi kuchotsa fumbi, carbon monoxide imapanikizidwa kufika pa 2 MPa ndi compressor, kenako imatenthedwa mpaka 150 °C ndi 160 g/L sodium hydroxide, ndikutumizidwa ku reactor kuti ipange yankho la sodium formate losungunuka. Yankho limayikidwa pa 600 g/L, ndikutumizidwa ku ketulo yochotsera madzi kuti itenthedwe ndikuyikidwa mu cholimba, kenako imatenthedwa ndikusungunuka, ndikuchotsedwa madzi pa 400 °C. Sodium oxalate yochotsera madzi imakonzedwa ngati suspension, ndipo lead sulfate imawonjezedwa pansi pa kusonkhezera pamene pH ikusungidwa pa 3-4. Zonyansa zosungunuka zimachotsedwa potsuka, kenako sulfuric acid yochulukirapo imawonjezedwa kuti ipange acidization kuti ipeze yankho la oxalic acid. Barium carbonate ndi 1% polyacrylamide zimawonjezedwa kuti ziume ndi sedimentation kuti zichotse zonyansa. Yankho limaziziritsidwa, limapangidwa kukhala crystallized, limasefedwa ndi centrifugation, ndikuumitsidwa kuti lipeze chinthu chomalizidwa.
