Hano hari itandukaniro twavuze muri make hagati ya Trivalent na Hexavalent chromes.
Itandukaniro Hagati ya Chromium ya Trivalent na Hexavalent
Hexavalentisahani ya chromiumni uburyo gakondo bwo gufata chromium (bikunze kwitwa plaque ya chrome) kandi birashobora gukoreshwa muburyo bwo gushushanya no gukora.Isahani ya chromium igerwaho igerwaho no kwibiza insina mu bwogero bwa chromium trioxide (CrO3) na aside sulfurike (SO4).Ubu bwoko bwa chromium butanga ruswa kandi ikarwanya kwambara, hamwe nubwiza bwiza.

Chromiumisahaniifite ibibi byayo, ariko.Ubu bwoko bwa plaque butanga umusaruro mwinshi ufatwa nkimyanda ishobora guteza akaga, harimo chromate ya sisitemu na barium sulfate.Chromium ya Hexavalent ubwayo ni ibintu byangiza na kanseri kandi bigengwa cyane na EPA.Mu myaka yashize, imodoka za OEM nka Chrysler zashyize ingufu mu gusimbuza chromium ya hexavalent hamwe n’ibidukikije byangiza ibidukikije.
Chromiumni ubundi buryo bwagushushanya Chrome, kandi ifatwa nkibidukikije byangiza ibidukikije kuri chromium ya hexavalent, hamwe nibintu byinshi biranga;kimwe na chrome ya hexavalent irangiza, chrome trivalent irangiza itanga ibishushanyo no kwangirika kandi iraboneka muburyo butandukanye bwamabara.Isahani ya chromium ikoreshwa ikoresha chromium sulfate cyangwa chromium chloride nkibigize byingenzi, aho gukoresha chromium trioxide;gukora chromium trivalent idafite uburozi kurenza chromium ya hexavalent.

Mugihe uburyo bwo gutondekanya chromium butoroshye bigoye kubigenzura, kandi imiti ikenewe ihenze kuruta iyakoreshejwe kuri chromium ya hexavalent, ibyiza byubu buryo bituma irushanwa-igiciro hamwe nubundi buryo bwo kurangiza.Inzira ntoya isaba imbaraga nke ugereranije na hexavalent kandi irashobora kwihanganira ihagarikwa ryubu, bigatuma irushaho gukomera.Uburozi bwa chromium butagaragara bivuze ko butagengwa cyane, kugabanya imyanda iteje akaga nibindi biciro byubahirizwa.
Hamwe n’amabwiriza agenga ibintu bishobora guteza akaga muri Amerika no mu bihugu by’Uburayi, hakenewe kurangiza ibidukikije byangiza ibidukikije nka chrome trivalent.
Hexavalent Chromium Plating Solution
Ububiko bwa chromium bukomeye, ubusanzwe bufite isahani ndende, bukoreshwa cyane mu bucukuzi bw'amabuye y'agaciro n'indege ndetse no mu bikoresho bya hydraulics n'ibikoresho byo gukora ibyuma.Zikoreshwa kandi mukurangiza ibikoresho byubuvuzi nububaga.
Hexavalent chromium electrolytes ikenera isoko ya chromium ion hamwe na catalizaires imwe cyangwa nyinshi kugirango ubone isahani.Gutegura inzira gakondo, byitwa kwiyuhagira bisanzwe, birimo chromium ya hexavalent na sulfate nkumusemburo wonyine.
Inyongeramusaruro zishobora kongerwaho muburyo busanzwe bwa chromium isahani ya chromium isahani yo kwiyuhagira kugirango yongere inzira yiswe ubwogero bwa catalizike kuva ubwo inyongeramusaruro zirimo byibura catalizari imwe yiyongera kuri sulfate.
Ikigereranyo cya Chromium Ikibaho
Electrolytes kubisubizo bya chromium trivalent itandukanye muri chimie, ariko byose birimo isoko ya chromium trivalent, ubusanzwe ikongerwaho nkumunyu wa sulfate cyangwa chloride.Harimo kandi ibikoresho bya solubilizing bihuza na chromium kugirango yemere gushira mubyifuzo byo kongera ubushobozi mubisubizo.
Ibikoresho byo guhanagura bikoreshwa mugufasha muburyo bwo kubitsa no kugabanya ubuso bwibisubizo byumuti.Kugabanuka kwubuso bwagabanutse cyane cyane kuvanaho ibicu kuri anode cyangwa cathode.Isahani yo gukora ikora nka chimie ya Nickel yo koga kuruta ubwogero bwa Hex chrome.Ifite idirishya rinini cyane kuruta idirishya rya Chrome.Ibyo bivuze ko ibyinshi mubikorwa bigomba kugenzurwa neza, kandi cyane cyane.Imikorere ya Trivalent Chrome irarenze iyo kuri Hex.Kubitsa nibyiza kandi birashobora kuba byiza cyane.
Isahani ya chromium ya Hexavalent ifite ibibi byayo, nyamara.Azwi nka kanseri ya kimuntu kandi irashobora gukurura ibibazo bikomeye byubuzima.Wibuke icyatumye Erin Brockovich aba izina ryurugo?Ubu bwoko bwa plaque butanga ibicuruzwa byinshi bifatwa nkibyago.
Isahani ya chromiumni ibidukikije byangiza ibidukikije kuruta chromium ya hexavalent;inzira ya electrodeposition isanzwe yemerwa kuba inshuro zirenga 500 uburozi burenze Chromium ya hexavalent.Inyungu nyamukuru yuburyo butatu bwa chromium ni uko ihindagurika.Gukwirakwiza amasahani birasa cyane, isahani ya barrale irashoboka kuri chrome trivalent, ntibishoboka hamwe na chrome ya hexavalent.
Hexavalent Vs Ikigereranyo cya Chromium

Ibyerekeye CheeYuen
Yashinzwe muri Hong Kong mu 1969,Yamazakini igisubizo gitanga ibice bya plastike no kuvura hejuru.Ibikoresho bifite imashini zigezweho hamwe numurongo wo kubyaza umusaruro (1 igikoresho cyo gutera no gutera inshinge, umurongo wa electroplating 2, imirongo 2 yo gushushanya, umurongo wa PVD 2 nizindi) kandi uyobowe nitsinda ryiyemeje ninzobere nabatekinisiye, CheeYuen Surface Treatment itanga igisubizo cyibisubizo kurichromed, gushushanya&Ibice bya PVD, kuva mubishushanyo mbonera byo gukora (DFM) kugeza PPAP hanyuma amaherezo ukarangiza gutanga igice kwisi yose.
Byemejwe naIATF16949, ISO9001naISO14001kandi yagenzuwe hamweVDA 6.3naCSR, Ubuvuzi bwa CheeYuen bwabaye isoko ryamamaye kandi ritanga umufatanyabikorwa w’umubare munini w’ibicuruzwa bizwi cyane n’abakora inganda z’imodoka, ibikoresho, n’inganda zo koga, harimo Continental, ALPS, ITW, Whirlpool, De'Longhi na Grohe, n'ibindi
Ufite ibitekerezo bijyanye niyi nyandiko cyangwa ingingo wifuza ko tubona mu gihe kizaza?
