Tili ndi gulu lathu lopeza phindu, gulu lopanga ndi kupanga, gulu laukadaulo, gulu la QC ndi gulu logwira ntchito yokonza ma phukusi. Tsopano tili ndi njira zabwino zogwirira ntchito pa ntchito iliyonse. Komanso, antchito athu onse ali ndi luso losindikiza mitu ya Mtengo Wogulitsa China Oxalic Acid 99 6% pa Ntchito Zoyeretsera Miyala Moyenera, Ngati pakufunika zina zowonjezera, muyenera kulumikizana nafe nthawi iliyonse!
Tili ndi gulu lathu lopeza phindu, gulu lopanga ndi kupanga zinthu, gulu laukadaulo, gulu la QC ndi gulu lopereka zinthu. Tsopano tili ndi njira zabwino zogwirira ntchito pa ntchito iliyonse. Komanso, antchito athu onse ali ndi luso lolemba nkhani. Cholinga chathu ndi kukhutira ndi makasitomala. Tikuyembekezera kugwirizana nanu ndikupereka ntchito zathu zabwino kwambiri zomwe zikugwirizana ndi zosowa zanu. Tikukulandirani mwansangala kuti mutilankhule nafe ndikutsimikiza kuti muli omasuka kuti mutilankhule nafe. Yang'anani malo athu owonetsera pa intaneti kuti muwone zomwe tingakuchitireni. Kenako titumizireni imelo zatsatanetsatane kapena mafunso anu lero.

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 maoda, ndipo tidzafotokoza mwatsatanetsatane momwe zinthu zidzayendere. (2) Kufufuza Nitrous Acid mu Kupanga Utoto wa Indigo
Pogwiritsa ntchito sodium nitrite popanga utoto wa indigo posindikiza mwachindunji ndi utoto wa naphthol AS, kupanga kwa sulfuric acid kumapanga nitrous acid (HNO2).
Izi zimapangitsa kuti mchere wa sodium wa naphthol AS pa nsalu ukhale wofiirira ngati chinthu chofiira, zomwe zimapangitsa kuti maziko ake akhale oyera. Pofuna kuchotsa nitrous acid, 1–2 g/L ya oxalic acid nthawi zambiri imawonjezeredwa ku yankho lopanga sulfuric acid, m'malo mwa zinthu zina zochepetsera (monga formic acid, urea, sulfure). Oxalic acid imachepetsa nitrous acid kukhala mpweya wa nayitrogeni, zomwe zimalepheretsa HNO kuti isasinthe utoto wa AS.
Equation ya reaction pakati pa oxalic acid ndi nitrous acid:
3H2C2O4+2HNO2→4H2+6CO2↑+N2↑
