Cov khoom siv
Manganese hais feem ntau yog siv rau hauv kev npaj cov alloys, roj teeb, tshuaj lom neeg kev lag luam thiab kev tswj ib puag ncig. Nyob rau hauv cov nqe lus ntawm kev npaj alloy, manganese hais feem ntau yog siv los tsim stainless hlau, cam khwb cia hlau, txhuas alloys, thiab lwm yam. Nyob rau hauv cov nqe lus ntawm cov roj teeb, manganese hais yuav siv tau los ua manganese lithium roj teeb thiab manganese lead roj teeb. Hauv kev lag luam tshuaj, manganese hais tuaj yeem siv los npaj cov khoom siv tshuaj xws li manganese oxide, manganese dioxide, thiab manganese sulfate. Tsis tas li ntawd, manganese hais kuj tuaj yeem siv los ua cov xim lossis cov khoom ntxiv hauv cov hlau, iav, ceramics thiab lwm yam lag luam. Hauv kev tswj hwm ib puag ncig, manganese hais tuaj yeem siv los kho manganese kuab paug hauv dej haus thiab kho ib puag ncig.
Ntim Thiab Cia
Ntim:
Tau ntim rau hauv lub hnab ntim dej pov thawj, 1000kg ib lub hnab lossis raws li koj xav tau.
Lus Cim: Cov tshuaj muaj pes tsawg leeg thiab qhov loj tuaj yeem ua kom zoo los ntawm cov neeg siv khoom xav tau
Cia:
Manganese pellets feem ntau yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo-ventilated ib puag ncig kom tsis txhob ya raws thiab kub. Nws raug nquahu kom khaws cov manganese pellets hauv cov thawv ntim cua kom tiv thaiv oxidation. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tau xyuam xim rau kev tiv thaiv hluav taws thiab tawg thaum lub sijhawm khaws cia, thiab tsis txhob sib xyaw nrog cov oxidants thiab cov khoom siv hluav taws xob. Tsis tas li ntawd, kev sib cuag nrog cov tshuaj xws li muaj zog acids thiab alkalis yuav tsum tau zam thaum lub sij hawm cia kom tsis txhob muaj tshuaj lom.
Kev Tiv Thaiv Kev Nyab Xeeb
Thaum koj siv cov tshuaj no, thov ceev faj txog nws raws li hauv qab no:
Nws yog heev flammable thiab lom los ntawm inhalation, nyob rau hauv kev sib cuag nrog daim tawv nqaij thiab yog hais tias nqos. Thov tshem tag nrho cov khaub ncaws uas tsis huv tam sim ntawd. Nws tiv nrog dej liberates tsis tshua muaj hluav taws xob gases thiab tuaj yeem ua rau kub hnyiab. Thaum sib cuag nrog qhov muag, yaug tam sim ntawd nrog dej kom ntau thiab nrhiav kev kho mob. Tsis tas li ntawd, cov tshuaj no ua rau khaus rau qhov muag thiab tawv nqaij. Thaum koj siv nws, hnav hnab looj tes tsim nyog thiab qhov muag / ntsej muag tiv thaiv. Thaum muaj xwm txheej lossis yog tias koj tsis xis nyob, nrhiav kev kho mob tam sim ntawd (qhia daim ntawv lo yog qhov ua tau).
