1.Ammonium sulfate, yomwe imadziwikanso kuti ammonium sulfate, ndiye feteleza woyamba wa nayitrogeni wopangidwa ndikugwiritsidwa ntchito kunyumba ndi kunja.Nthawi zambiri amatengedwa ngati feteleza wamba wa nayitrogeni, wokhala ndi nayitrogeni pakati pa 20% ndi 30%.Ammonium sulphate ndi asidi wamphamvu wopanda mchere wamchere, ndipo yankho lamadzi ndi acidic.Ammonium sulphate ndi mtundu wa feteleza wa nayitrogeni ndi feteleza wa asidi mu feteleza wa makina osagwiritsa ntchito mankhwala.Amagwiritsidwa ntchito payekha kwa nthawi yayitali, zomwe zimapangitsa kuti nthaka ikhale acidic ndi kuuma ndipo imayenera kukonzedwa bwino.Ammonium sulphate sangagwiritsidwe ntchito kupanga feteleza wachilengedwe.Komanso, fetereza wa asidi sangathe kugwiritsidwa ntchito ndi feteleza wamchere, ndipo hydrolysis iwiri ndiyosavuta kutaya feteleza.
2.Pure ammonium sulfate ndi galasi loyera, lomwe limayamba kuwola kukhala ammonia ndi ammonium bisulfate likatenthedwa mpaka 100 ℃.Zomwe zimapangidwira zimakhala zachikasu kapena zotuwa, zokhala ndi hygroscopicity pang'ono ndipo sizosavuta kugwirizanitsa, choncho zimakhala zosavuta kuzisunga, komanso zimasungunuka m'madzi, zosasungunuka mu ethanol ndi acetone.Amagwiritsidwanso ntchito ngati analytical reagent (precipitant, masking agent), kuthandizira electrolyte pakuwunika kwa electrochemical, sing'anga ya chikhalidwe cha microbial ndi kukonzekera mchere wa ammonium.
Kugwiritsa ntchito
1.Mainly ntchito ngati fetereza, oyenera mitundu yonse ya nthaka ndi mbewu.
2.Imagwiritsidwa ntchito ngati reagent yowunikira komanso kutulutsa kwa protein.
3.Used monga solder, nsalu fireproof wothandizira, etc.
4.Itha kugwiritsidwa ntchito ngati feteleza, solder, nsalu yotchinga moto, wothandizira salting ndi osmotic pressure regulator muzamankhwala.
5.Makampani opanga mankhwala amagwiritsidwa ntchito ngati zopangira zopangira hydrogen peroxide, ammonium alum ndi ammonium chloride, ndipo makampani opanga kuwotcherera amagwiritsidwa ntchito ngati kuwotcherera.Makampani opanga nsalu amagwiritsidwa ntchito ngati cholepheretsa moto pansalu.Makampani opanga ma electroplating amagwiritsidwa ntchito ngati chowonjezera pakusamba kwa electroplating.Amagwiritsidwa ntchito ngati feteleza wa nayitrogeni paulimi ndipo ndi oyenera dothi ndi mbewu.Zakudya zamagulu amafuta zimagwiritsidwa ntchito ngati zokometsera mtanda ndi chakudya cha yisiti.
6.Dough conditioner;Zakudya za yisiti.Amagwiritsidwa ntchito ngati gwero la nayitrogeni pachikhalidwe cha yisiti pakupanga yisiti yatsopano, ndipo mlingo wake sunatchulidwe.Kuchuluka kwa yisiti yogwiritsidwa ntchito mu mkate ndi pafupifupi 10% (pafupifupi 0.25% ya ufa wa tirigu).GB 2760-90 yalembedwa ngati zothandizira kukonza.
7.Biological agents, protein precipitated, chromatographic reagents, kufufuza mkodzo, chikhalidwe sing'anga kukonzekera mu kuswana haploid.Mankhwala amagwiritsidwa ntchito ngati salting out agent, chothandizira mtundu wa msuzi wa chakudya, buku la mankhwala, ndi chikhalidwe cha yisiti popanga yisiti yatsopano.Amagwiritsidwanso ntchito ngati chothandizira podaya utoto wa asidi komanso chowotcha pachikopa.
