Takhala onyada chifukwa cha kukhutitsidwa kwakukulu ndi ogula komanso kulandiridwa kwakukulu chifukwa cha kufunafuna kwathu kwapamwamba kwambiri pa malonda kapena ntchito ndi ntchito ya Maleic Anhydride Yogulitsidwa Kwambiri Yogwiritsidwa Ntchito Pakupanga Zipangizo Zapamwamba Zamakampani Zopangira Mankhwala Ophera Tizilombo, Pokhapokha ngati zinthu zathu zonse zili bwino kuti zikwaniritse zosowa za makasitomala, zinthu zathu zonse zimawunikidwa mosamala tisanatumize.
Takhala onyada chifukwa cha kukhutitsidwa kwakukulu ndi makasitomala komanso kulandiridwa bwino chifukwa cha kufunafuna kwathu zinthu zabwino kwambiri pa malonda kapena ntchito ndi ntchito, kuti makasitomala azidzidalira kwambiri ndikupeza ntchito yabwino kwambiri, timayendetsa kampani yathu moona mtima, moona mtima komanso mwaluso kwambiri. Timakhulupirira kwambiri kuti ndife okondwa kuthandiza makasitomala kuyendetsa bizinesi yawo bwino, ndipo upangiri wathu waluso ndi ntchito zathu zitha kupangitsa makasitomala kusankha bwino.

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 za njira yopangira. Ukadaulo wa Njira Yopangira Maleic Anhydride
Maleic anhydride ndi mankhwala ofunikira kwambiri achilengedwe, omwe amagwiritsidwa ntchito kwambiri m'mafakitale monga mapulasitiki, utoto, ndi mankhwala. Pansipa, tikuwonetsani njira zopangira maleic anhydride.
Pali njira zinayi zodziwika bwino zopangira maleic anhydride: njira ya phenoxypropanol, njira ya ethylene dehydrogenation, njira ya phthalic anhydride, ndi njira ya mankhwala a malasha.
Choyamba ndi njira ya phenoxypropanol: Njirayi imaphatikizapo kuchita benzene ndi benzyl oxide kuti apange phenoxypropanol, yomwe kenako imasungunuka ndi mpweya kuti ipange maleic anhydride. Ubwino wake ndi monga kutentha kochepa kwa reaction, ma reactants osavuta kufikako, komanso kutulutsa kwakukulu.
Njira yotsatira ndi njira yochotsera ethylene: Mu njira iyi, ethylene imachotsedwa mu tartaric acid kuti ipange acrolein; kenako acrolein imachotsedwa mu hydrogenation ndi deoxygenation kuti ipeze maleic anhydride. Ubwino wa njira iyi ndi momwe imagwirira ntchito pang'ono komanso kuthekera kogwiritsa ntchito ethylene mwachindunji ngati chinthu chopangira.
Njira yachitatu ndi njira ya phthalic anhydride: Apa, phthalic anhydride imagwiritsidwa ntchito ngati zopangira, ndipo maleic anhydride imapangidwa kudzera mu okosijeni wa okosijeni ndi decarboxylation. Njirayi imadziwika ndi zopangira zomwe zimapezeka mosavuta komanso njira yosavuta yopangira.
Pomaliza, njira ya mankhwala a malasha: Njira imeneyi imagwiritsa ntchito malasha ngati zinthu zopangira, zomwe zimaphikidwa pa kutentha kwambiri kuti zipange mpweya; zotsatira zake zimakhala za okosijeni ndi decarboxylation kenako zimapanga maleic anhydride. Ubwino wake waukulu ndi wakuti malasha ndi chinthu chomwe chimapezeka kwambiri, zomwe zimathandiza kuti malasha agwiritsidwe ntchito bwino.
