Chogulitsa choyeracho chimawoneka ngati makhiristo oyera, pomwe chapamwamba kwambiri cha mafakitale ndi madzi owonekera opanda mtundu kapena achikasu opepuka. Amasungunuka mosavuta m'madzi, methanol ndi ethanol. 1-Hydroxyethane-1,1-diphosphonic acid ndi mankhwala opangira mankhwala, omwe amagwiritsidwa ntchito kwambiri pochiza madzi m'mafakitale, zinthu zoyeretsera m'nyumba ndi zinthu zosamalira munthu payekha.

Kagwiritsidwe Ntchito
Chogulitsachi ndi chinthu chachikulu chomwe chimagwiritsidwa ntchito popanga ma electroplating opanda cyanide. Chikapangidwa kukhala yankho la mkuwa lopanda cyanide, chimatha kuyika mkuwa mwachindunji pazipangizo za sodium-iron ndi kumatira bwino kwambiri. Chophimbacho chili ndi malo osalala komanso mtundu wabwino. Mlingo wonse wa yankho la 60% ndi 100 mpaka 120 ml pa lita imodzi, ndipo mlingo wa copper sulfate ndi magalamu 15 mpaka 20 pa lita imodzi. Kuphatikiza apo, kumiza zigawo zophimbidwa mu yankho la 1% mpaka 2% la chinthuchi kuti ziyambe kugwira ntchito pamwamba pake musanagwiritse ntchito ma electroplating kungawonjezere mphamvu ya electroplating.
Hydroxyethylidene Diphosphonic Acid (HEDP) ndi mtundu watsopano wa electroplating complexing agent yopanda chlorine. Imagwira ntchito ngati chokhazikika chapamwamba cha madzi m'madzi ozizira komanso imagwira ntchito yoletsa dzimbiri komanso kupewa kukula. Ndi imodzi mwa mankhwala ochizira madzi a polyphosphonic acid. Palinso zinthu zina zopangidwa m'nyumba zamtunduwu, monga Amino Trimethylene Phosphonic Acid (ATMP) yokhala ndi formula \([CH_2PO(OH)_2]_3N\), Ethylene Diamine Tetra Methylene Phosphonic Acid (EDTMP), ndi zina zambiri.
Ma polyphosphonic acid achilengedwe ndi gulu la mankhwala ochizira madzi omwe adapangidwa kumapeto kwa zaka za m'ma 1960 ndipo adadziwika pafupifupi m'ma 1970. Kutulukira kwa mankhwala awa kunapita patsogolo kwambiri paukadaulo wochizira madzi. Poyerekeza ndi ma polyphosphates osapangidwa, ma polyphosphonic acid achilengedwe ali ndi kukhazikika kwabwino kwa mankhwala, kukana hydrolysis, kulekerera kutentha kwambiri, mlingo wochepa, komanso kuphatikiza dzimbiri ndi magwiridwe antchito oletsa kukula.
Amagwira ntchito ngati zoletsa kutupira kwa cathodic ndi zoletsa zoletsa masikelo osagwiritsidwa ntchito ndi stoichiometric. Akaphatikizidwa ndi zinthu zina zochizira madzi, amapereka zotsatira zabwino zogwirizana. Amasonyeza mphamvu yabwino kwambiri yogwiritsira ntchito ma ayoni ambiri achitsulo kuphatikizapo calcium, magnesium, copper ndi zinc, komanso ali ndi zotsatira zabwino zoletsa kuchitapo kanthu pa mchere wosapangidwa ndi zitsulozi monga calcium sulfate (\(CaSO_4\)), calcium carbonate (\(CaCO_3\)) ndi magnesium silicate (\(MgSiO_3\)). Chifukwa chake, amagwiritsidwa ntchito kwambiri muukadaulo wochizira madzi.
Chothandizira cha phosphorylation cha serine ndi pyranose yotetezedwa.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
