Siv:used as chemical reagents, pottery and glass etching, electroplating, brewing, fermented industrial preservatives and bacterial inhibitors. Nws kuj yog siv rau cov hlau smelting thiab tej hub tsim.

Daim Ntawv Thov:

1. Siv ua cov iav etching, tshuaj tua kab mob, cov tshuaj tiv thaiv, cov tshuaj kho kom zoo nkauj ntawm silicon steel phaj, kuj siv nyob rau hauv kev tsim khoom ntawm ceramics thiab maglocesium alloys.

2. Nws tuaj yeem siv los ua tshuaj reagent, iav etch tus neeg sawv cev (cov tshuaj tua kab mob rau kev ua qoob loo ntawm hydrentation) Nws tseem siv rau kev tsim khoom ceramics, cov tshuab ntxhua khaub ncaws siv, tu thiab descaling ntawm boiler pub dej system thiab chav tiam cov khoom siv, thiab acidfing kev kho ntawm cov roj av roj hmab. Kuj tseem siv raws li alkylation, isomerization centalyst Cheebtsam.

3. Siv rau cov roj av activation kev kho mob, kev tsim khoom lag luam magnesium thiab cov hlau nplaum magnesium. Used as glass matting, frosting, etching agent, used as wood protection agent, aluminum brightening agent, textile industry used as rust remover, can also be used in electroplating, electronic industry, as an analytical reagent.

4. Siv los ua ib qho kev ntsuas tshuaj thiab cov kab mob uas tsis muaj kab mob.

5. Txheeb xyuas cov reagent. Siv rau ceramic thiab iav nto engraving. Kev rho tawm ntawm cov khoom siv. Kev npaj ntawm hydrogen fluoride hauv chav kuaj. Electroplating.

Kev ua haujlwm pov tseg thiab chaw khaws khoom thiab tsheb thauj mus los:

Kev ceev faj:Kaw cov lag luam, ntxiv dag zog rau qhov cua. Cov neeg ua haujlwm yuav tsum raug cob qhia tshwj xeeb thiab nruj me ntsis ua haujlwm los ntawm cov txheej txheem kev ua haujlwm. Nws raug pom zoo tias cov neeg ua haujlwm hnav lub ntsej muag plua plav plua plav Zam kev ua hmoov av. Zam kev sib cuag nrog cov kua qaub. Thaum tuav, lub teeb thauj khoom thiab kev thauj khoom yuav tsum ua kom tiv thaiv kev puas tsuaj rau ntim thiab ntim. Nruab nrog cov khoom siv kho kom muaj dej kub ceev. Ib lub taub ntim khoob yuav muaj cov teeb meem tsis zoo.

Cia Kev ceev faj:Khaws rau hauv qhov chaw txias, qhuav thiab zoo-ventilated tsev rau khoom. Tseg kom deb ntawm hluav taws thiab tshav kub. Khaws lub thawv ntim. Yuav tsum tau muab khaws cia cais tawm los ntawm acids, tsis txhob sib xyaw cia. Qhov chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog los muaj cov kua zaub.

Cov Qauv Ntim:ntoo decond ntoo sab nraum ampoule fwj; Threaded iav fwj, hlau taub hau pressed iav fwj, yas hwj los yog cov hlau ntoo sab nraud. Yo dej noo-pov thawj thiab ntim khoom thiab kaw cia. Lub hnab ntim khoom: 25kg / hnab.

Kev ceev faj kev ceev faj:Cov tsheb thauj mus los yuav tsum tau nruab nrog cov khoom siv hluav taws thiab ntau thiab ntau cov khoom siv hluav taws thiab dej kom ceev. Nyob rau lub caij ntuj sov, nws yog qhov zoo tshaj plaws nkoj thaum sawv ntxov thiab yav tsaus ntuj. Lub trough (tank) tsheb siv hauv kev thauj mus los yuav tsum tau npaj cov saw hlau, thiab ib qho kev faib tawm tuaj yeem muab cov hluav taws xob tsis zoo tsim hluav taws xob los ntawm kev poob siab. Nws yog nruj me ntsis txwv tsis pub sib tov nrog oxidizer. Thaum lub sijhawm thauj mus los, nws yuav tsum tau tiv thaiv los ntawm lub hnub kis, nag thiab kub kub. Txav deb ntawm nplaim taws, kub qhov chaw thiab kub thaj tsam thaum lub sijhawm nres. Cov kev tso tawm ntawm cov tsheb uas nqa cov ntawv yuav tsum tau nruab nrog cov khoom siv hluav taws retardant. Kev thau khoom thiab tsis siv tshuaj nrog cov cuab yeej siv cov khoom siv cov khoom siv uas yooj yim los tsim cov txim taws. Kev thauj hauv kev yuav tsum ua raws txoj kev uas tau hais tseg, tsis txhob nyob hauv thaj chaw nyob hauv nroog thiab muaj cov neeg coob coob. Nws yog txwv tsis pub plam lawv hauv kev thauj mus los. Cov nkoj ntoo thiab cov nkoj maj mam txwv tsis pub muaj kev thauj mus los.
