Ammonia (NH3)

Technical Parameters

Cov kua ammonia, tseem hu ua anhydrous ammonia, yog cov kua tsis muaj xim uas muaj ntxhiab tsw ntxhiab thiab corrosive. Raws li ib qho tseem ceeb ntawm cov khoom siv raw khoom, ammonia feem ntau yog siv kom tau cov kua ammonia los ntawm kev nias los yog txias gaseous ammonia rau kev yooj yim ntawm kev thauj mus los thiab khaws cia. Cov kua ammonia yog yooj yim soluble hauv dej, thiab tsim ammonium ion NH4 + thiab hydroxide ion OH- tom qab yaj hauv dej. Cov tshuaj yog alkaline. Cov kua ammonia yog siv dav hauv kev lag luam, yog corrosive thiab yooj yim rau volatilize, yog li nws cov tshuaj lom neeg raug mob siab heev. Cov kua ammonia feem ntau yog siv los ua cov kuab tshuaj inorganic non-aqueous hnyav, thiab tseem siv los ua cov tub yees thiab cov khoom siv raw khoom. Siv rau hauv kev tsim cov chiv, tawg, yas thiab tshuaj fibers. Cov hlau-kua ammonia tov muaj zog txo cov khoom thiab yog dav siv nyob rau hauv inorganic thiab organic synthesis. Nws yog feem ntau siv nyob rau hauv lub synthesis ntawm kev hloov hlau tebchaw nrog tsawg oxidation xeev. Nyob rau hauv cov organic chemistry, sodium-kua ammonia tov yog siv nyob rau hauv lub Birch txo cov tshuaj tiv thaiv kom txo tau cov aromatic nplhaib rau lub cyclohexadiene nplhaib system. Cov kua ammonia daws ntawm sodium los yog lwm yam hlau kuj tuaj yeem txo alkynes los tsim cov trans-olefins. Hauv kev lag luam tshuaj, kua ammonia yog ib qho ntawm cov khoom siv raw rau kev tsim cov urea. Nyob rau tib lub sijhawm, vim tias nws cov khoom siv tshuaj tshwj xeeb, nws tau siv zoo hauv kev lag luam semiconductor thiab metallurgical. Cov kua ammonia feem ntau yog khaws cia rau hauv lub tog raj kheej lossis lub tank steel, thiab tsis tuaj yeem ua ke nrog acetaldehyde, acrolein, boron thiab lwm yam khoom. Cov kua dej ammonia yuav tsum tau muab cia rau hauv lub tsev rau khoom lossis ntawm lub platform nrog lub tsev. Thaum muab tso rau hauv qhov qhib cua, nws yuav tsum tau npog nrog lub tsev pheeb suab kom tiv thaiv tshav ntuj ncaj qha. Lub tog raj kheej steel thiab lub tank tsheb thauj khoom uas nqa cov kua ammonia yuav tsum raug tiv thaiv los ntawm tshav kub thaum thauj, thiab cov foob pob hluav taws raug txwv nruj heev.

Daim ntawv thov:

1. Tshuaj chiv:
Cov kua ammonia feem ntau yog siv los tsim cov nitric acid, urea thiab lwm yam tshuaj chiv.
 
2. Cov khoom siv raw:
Nws tuaj yeem siv los ua cov khoom siv raw hauv tshuaj thiab tshuaj tua kab.
 
3. Kev tsim cov foob pob hluav taws, missile propellant:
Hauv kev lag luam tiv thaiv, siv hauv kev tsim cov foob pob hluav taws, missile propellant.
 
4. Cov tub yees:
Yuav siv tau raws li lub tub yees.
 
5. Mercerized tiav ntawm textiles:
Cov kua ammonia kuj tuaj yeem siv rau Mercerized tiav ntawm textiles.

Qhov zoo:

1. Peb lub Hoobkas tsim NH3 los ntawm cov khoom siv raw khoom zoo, dhau li tus nqi pheej yig.
2. Lub NH3 yog tsim tom qab ntau lub sij hawm cov txheej txheem ntawm purification thiab rectification nyob rau hauv peb lub Hoobkas.Qhov kev tswj xyuas hauv internet tau lav cov roj purity txhua theem.Cov khoom tiav yuav tsum ua raws li tus qauv.
3. Thaum lub sij hawm txhaws, lub tog raj kheej yuav tsum tau ua ntej qhuav rau ib lub sij hawm ntev (tsawg kawg 16 teev), ces peb nqus lub tog raj kheej, thaum kawg peb tshem nws nrog cov roj qub.Tag nrho cov txheej txheem no xyuas kom meej tias cov roj ntshiab hauv lub tog raj kheej.
4. Peb muaj nyob rau hauv Gas teb rau ntau xyoo, kev nplua nuj nyob rau hauv ntau lawm thiab export cia peb yeej cov neeg muas zaub 'kev ntseeg siab, lawv txaus siab rau peb cov kev pab cuam thiab muab lus zoo rau peb.
