Cholinga chathu chachikulu ndicho kukhutitsidwa kwa makasitomala. Timapereka chithandizo chaukadaulo, chapamwamba, chodalirika komanso chogwira ntchito nthawi zonse pa 100% Original Factory 6153-56-6 Fengda H2c2o4 99.6 Industrial Grade Dihydrate Ethanedioic Oxalic Acid Crystal Price, Ndipo titha kulola zinthu zilizonse zomwe makasitomala akufuna. Onetsetsani kuti mwapereka chithandizo chabwino kwambiri, chapamwamba kwambiri, komanso chotumiza mwachangu.
Cholinga chathu chachikulu ndicho kukhutitsidwa kwa makasitomala. Timasunga ukatswiri, khalidwe, kudalirika, ndi utumiki nthawi zonse. Takhala tikupitirizabe kudzipereka ku bizinesi yathu monga "Ubwino Choyamba, Kulemekeza Mapangano ndi Kuyimirira ndi Mbiri Yabwino, kupatsa makasitomala zinthu ndi ntchito zokhutiritsa." Anzathu akunyumba ndi akunja akulandiridwa mwachikondi kuti adzakhazikitse ubale wosatha ndi ife.

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 funso kwa aliyense mwa ogulitsa athu kuti mudziwe zambiri zokhudza dongosolo, ndipo tidzafotokoza mwatsatanetsatane za njira yogwiritsira ntchito. Fujian Institute of Structure of Matter, Chinese Academy of Sciences, yachita kafukufuku pa chiŵerengero cha zipangizo zopangira ndi mikhalidwe yosiyanasiyana ya liwiro la mlengalenga pa kapangidwe ka dimethyl oxalate ka catalytic mu kafukufuku wa ma catalyst a mlengalenga wa catalytic coupling wa CO ndi oxalic acid, ndipo yasankha mikhalidwe yoyenera yochitira. Pd (2.0%)/α-Al₂O₃ catalyst yabwino idapeza phindu la space-time la 999 g/L·h pansi pa mikhalidwe ya mlengalenga, 140 °C, CO/CH₃ONO=1.5, ndi liwiro la mlengalenga la 3000/h. Bungweli linagwirizana ndi Fujian Petrochemical Design Institute ndi Fujian Nanqing Ammonia Plant kuti achite mayeso oyeserera a 100 t/a pobwezeretsa CO kuchokera ku ammonia copper scrubbing yopangidwa, kapangidwe ka dimethyl oxalate ka atmospheric pressure, ndi hydrolysis kupita ku oxalic acid.
Poyerekeza ndi njira ya liquid-phase, njira iyi ili ndi kusankha kwakukulu, njira yosavuta, kuyera kwambiri kwa zinthu, komanso mtengo wotsika wopanga. Ikhoza kugwiritsa ntchito mpweya wachilengedwe kapena malasha ngati zinthu zopangira, komanso ingagwiritse ntchito carbon monoxide yomwe yapezeka kuchokera ku ammonia copper scrubbing kapena yellow phosphorus furnace, blast furnace, ndi converter tail gas ngati gwero la mpweya wa carbon monoxide. Nthawi yomweyo, imatha kupereka zinthu zotsika mtengo zopangira ethylene glycol ndi synthesis yogwirizana ndi oxalate ester ngati intermediate.
