Siv:
Kev ua liaj ua teb siv: raw khoom ntawm phosphate fertilizer thiab pub cov as-ham
Kev lag luam siv: chemical raw khoom
1. Tiv thaiv cov hlau los ntawm corrosion
2.Mixed nrog nitric acid ua tshuaj polishing tus neeg saib xyuas kom txhim kho qhov chaw tiav ntawm cov hlau
3.Material ntawm phosphatide uas yog siv los tsim cov khoom siv ntxhua khaub ncaws thiab tshuaj tua kab
4.Kev tsim cov phosphorus uas muaj cov ntaub ntawv flameretardant.
Khoom noj khoom haus additives siv: acidic flavoring, Poov Nutri-ents, xws li coca-cola.
Kev siv kho mob: los tsim cov tshuaj uas muaj phos-phorus, xws li Na 2 Glycerophosphat
Nyob rau hauv ntau yam kev ua ub no ntawm peb cov tib neeg, muaj phosphates, xws li zaub mov, kev lag luam, chiv, polishing, thiab lwm yam. Qhov no yog ib tug nplua nuj daim ntawv thov teb, thiab nyob rau hauv txhua daim ntawv thov teb acid.
Txawm li cas los xij, peb tsis tshua hais txog cov npe ntawm phosphate hauv peb lub neej. Ntawm ib sab, nws yog vim tias phosphate tsis yog ib yam khoom uas peb yuav tiv tauj hauv peb lub neej, thiab nws yog ntau dua hauv kev ua, kev tsim khoom, thiab kev tsim khoom.
Ntawm qhov tod tes, nws yog vim muaj phosphoric acid ntau dua, ib qho ntawm cov khoom lag luam tshwm sim ntawm cov ntim lossis phau ntawv qhia, thiab tus neeg nruab nrab yuav tsis them nyiaj tshwj xeeb rau cov no.
Yog li hnub no peb yuav tham nrog koj txog nws. Nws zoo nkaus li tias "tsis pom" phosphate hauv peb lub neej yog qhov tseem ceeb:
1. Hauv kev lag luam tshuaj, nws tuaj yeem siv los ua hlau phosphate, thiab lwm yam;
2. Koj tuaj yeem siv cov khoom noj poov xab los yog cov kua qaub xws li cola, npias, khoom qab zib, cov roj pleev xim, cov khoom noj siv mis, dej haus, thiab lwm yam hauv kev lag luam khoom noj khoom haus;
3. Nws tuaj yeem siv los tsim cov cement refractory. Cov cement no tuaj yeem ua rau lub neej ua haujlwm ntawm steel refiners rau qee yam;
4. Siv nws tus kheej chemistry tuaj yeem ua cov xim hlau xeb hauv kev lag luam txheej kom txo cov khoom poob;
5. Nws tuaj yeem siv los teeb tsa lub tshuab ntxhua khaub ncaws. Lub tshuab ntxhua khaub ncaws no tshwj xeeb yog tsim los tshem tawm cov stains uas yuav tshwm sim ntawm cov ntawv luam tawm ntawm cov luam ntawv hauv kev lag luam luam ntawv;
6. Koj tuaj yeem txhuam cov khoom txhuas vim nws tuaj yeem siv los kho cov tshuaj thiab electrolytic polishing kua rau phosphorize hlau nto;
7. Thaum cov roj hmab pulp xav tau thaum lub sijhawm tsim khoom, nws tuaj yeem siv los ua raw khoom rau coagulants thiab inorganic binders;
8. Nws kuj yog lub hom phiaj feem ntau nyob rau hauv peb, uas yog siv nws los tsim high-concentration ntawm phosphate fertilizer thiab compound fertilizer.
Tsis tas li ntawd, muaj cov tshuaj-qib phosphates uas yuav siv tau rau kev tsim tshuaj, polymer phosphates rau manufacturing polyphosphoos, organic hluavtaws raw cov ntaub ntawv, thiab lwm yam. Cov no yog tag nrho cov kev siv ntawm phosphate.
