Mibvunzo Inowanzo bvunzwa

Unoda rubatsiro here? Iva nechokwadi chekushanyira maforamu edu ekutsigira kuti uwane mhinduro dzemibvunzo yako!

Tinogona here kudhinda logo yedu pachigadzirwa?

Ehe, tinogona kuzviita. Ingotumirai dhizaini yelogo yenyu.

Munogamuchira maodha madiki here?

Ehe. Kana uri mutengesi mudiki kana kuti uri kutanga bhizinesi, tinoda kukura newe. Uye tinotarisira kushanda newe kwenguva refu.

Ko mutengo wacho wakaita sei? Unogona here kuita kuti ive yakachipa?

Tinogara tichitora rubatsiro rwemutengi sechinhu chinonyanya kukosha. Mutengo unogona kutaurwa nezvawo mumamiriro ezvinhu akasiyana, tiri kukuvimbisa kuti uchawana mutengo unokwikwidzana zvakanyanya.

Munopa mienzaniso yemahara here?

Zvinofadza kuti munogona kutinyorera wongororo dzakanaka kana muchida zvigadzirwa zvedu nebasa redu, tichakupai mimwe mienzaniso yemahara pakutenga kwenyu kunotevera.

Unokwanisa here kuendesa zvinhu nenguva?

Ehe, takaita basa iri kwemakore akawanda, vatengi vazhinji vanoita chibvumirano neni nekuti tinokwanisa kuendesa zvinhu nenguva uye kuchengetedza zvinhu zvakanaka!

Ndingashanyira kambani yenyu nefekitori kuChina here?

Ehe. Munogamuchirwa kushanyira kambani yedu muZibo, China. (Nzira yekutyaira ye1.5H kubva kuJinan)

Ndingaisa sei odha?

Munogona kungotumira mibvunzo kune chero mumiriri wedu wekutengesa kuti muwane ruzivo rwakadzama rweodha, uye isu tichatsanangura maitiro acho.2.3 Nzira yeSodium Formate
Kugadzirwa kweoxalic acid nenzira yesodium formate kwakakamurwa kuva nzira ye lead uye nzira ye calcium. Carbon monoxide inotorwa ne sodium hydroxide solution kuti iwane sodium formate, iyo inobva yabviswa hydrogenation kuti igadzire sodium oxalate. Iyo yekupedzisira inosangana ne lead sulfate (nzira ye lead) kana calcium hydroxide (nzira ye calcium) kuti igadzire lead oxalate precipitate kana calcium oxalate precipitate, iyo inobva yaiswa acid ne sulfuric acid kuti iwane oxalic acid.
Nzira yekugadzira oxalic acid: Mushure mekusuka, kusukwa kwealkali, uye kubvisa guruva, kabhoni monoxide inomanikidzwa kusvika 2 MPa necompressor, yopiswa kusvika 150 °C ne 160 g/L sodium hydroxide, yotumirwa kune reactor kuti igadzire sodium formate solution. Mhinduro yacho inosanganiswa kusvika 600 g/L, yotumirwa mukettle yekudzima hydrogenation kuti ipiswe uye isanganiswe kuita solid, yozopiswa uye yanyungudutswa, uye yobviswa hydrogenation pa 400 °C. Sodium oxalate isina hydrogenation inogadzirwa kuita suspension, uye lead sulfate inowedzerwa ichikurunga uku pH ichiramba iri pa 3–4. Tsvina inonyunguduka inobviswa nekusukwa, uye sulfuric acid yakawandisa inowedzerwa kuti iwane acidification kuti iwane oxalic acid solution. Barium carbonate ne 1% polyacrylamide zvinowedzerwa kuti zviome uye zviome kuti zvibvise tsvina. Mhinduro yacho inotonhodzwa, inocheneswa, inosefetwa ne centrifugation, uye inoomeswa kuti pave nechigadzirwa chapera.
