Hot galvanizing, yomwe imadziwikanso kuti hot-dip galvanizing ndi yotentha-kuviika galvanizing, ndi njira yabwino yotetezera dzimbiri zachitsulo, zomwe zimagwiritsidwa ntchito popanga zitsulo ndi zida m'mafakitale osiyanasiyana.Ndi njira zamakono zopezera zokutira pomiza zitsulo, zitsulo zosapanga dzimbiri, chitsulo chosapanga dzimbiri ndi zitsulo zina muzitsulo zosungunuka zamadzimadzi kapena aloyi.Ndi njira yomwe imagwiritsidwa ntchito kwambiri pazitsulo zachitsulo zomwe zimagwiritsidwa ntchito bwino komanso mtengo padziko lapansi masiku ano.Zopangira malata otentha zimakhala ndi gawo losayerekezeka komanso losasinthika pochepetsa dzimbiri ndikutalikitsa moyo, kupulumutsa mphamvu ndi zida zachitsulo.Panthawi imodzimodziyo, zitsulo zokutidwa ndizinthu zazing'ono zomwe zimakhala ndi mtengo wowonjezera wothandizidwa ndi wotsogozedwa ndi boma.
Njira yopanga
Kupanga ndi kukonza kanasonkhezereka zitsulo koyilo akhoza kugawidwa mu masitepe atatu: choyamba, koyilo lonse la Mzere zitsulo adzakhala kuzifutsa kwa dzimbiri kuchotsa ndi decontamination kuti pamwamba kanasonkhezereka zitsulo Mzere owala ndi woyera;Pambuyo pickling, adzakhala kutsukidwa mu ammonium kolorayidi kapena nthaka kolorayidi amadzimadzi njira kapena ammonium kolorayidi ndi nthaka mankhwala enaake osakaniza amadzimadzi njira, ndiyeno anatumiza mu otentha kuviika kusamba kwa galvanizing ndondomeko;Ntchito yopangira malata ikatha, imatha kusungidwa ndi kupakidwa.

Mbiri ya chitukuko cha galvanizing otentha
Kupaka malata otentha kunayambika pakati pa zaka za m'ma 1800.Idapangidwa kuchokera ku njira yopangira malata otentha ndipo yalowa m'zaka za zana lachinayi.Mpaka pano, galvanizing yotentha akadali njira yogwiritsidwa ntchito kwambiri komanso yothandiza popewera dzimbiri.
Mu 1742, Dr. Marouin anachita upainiya woyesera pa zitsulo zotenthetsera zoviikidwa m'madzi ndipo anaziwerenga ku Royal College of France.
Mu 1837, Sorier wa ku France anafunsira patent kwa otentha-kuviika galvanizing ndi kuika patsogolo lingaliro ntchito galvanic selo njira kuteteza zitsulo, ndiko kuti, ndondomeko galvanizing ndi kupewa dzimbiri pamwamba chitsulo.M’chaka chomwecho, Crawford wa ku United Kingdom anafunsira chiphaso cha zinc plating pogwiritsa ntchito ammonium chloride monga zosungunulira.Njirayi yatsatiridwa mpaka pano pambuyo pa kukonza zambiri.
Mu 1931, Sengimir, injiniya wodziwika bwino kwambiri pamakampani amakono opanga zitsulo, adamanga mzere woyamba padziko lonse lapansi wopangira malata otentha opangira zitsulo ndi njira yochepetsera haidrojeni ku Poland.Njirayi inali yovomerezeka ku United States ndi mzere wa mafakitale otentha-dip galvanizing wotchedwa Sengimir unamangidwa ku United States ndi Maubuge Iron ndi Steel Plant ku France mu 1936-1937, motero, kupanga nyengo yatsopano yopitilira, yapamwamba- liwiro ndi apamwamba otentha-kuviika galvanizing kwa Mzere zitsulo.
M'zaka za m'ma 1950 ndi 1960, United States, Japan, Britain, Germany, France, Canada ndi maiko ena motsatizana amapanga mbale zazitsulo zotayidwa.
Kumayambiriro kwa zaka za m'ma 1970, kampani ya Bethlehem Iron and Steel inapanga zida zokutira za Al-Zn-Si zokhala ndi dzina lamalonda la Galvalume, lomwe limakhala ndi kukana kwa dzimbiri nthawi 2-6 kuposa zokutira kwa zinki koyera.
M'zaka za m'ma 1980, aloyi yotentha ya zinki-nickel inatchuka kwambiri ku Ulaya, America ndi Australia, ndipo ndondomeko yake inatchedwa Technigalva Pakalipano, Zn-Ni-Si-Bi yapangidwa pamaziko awa, omwe amatha kulepheretsa kwambiri Sandelin. pakuwotcha kwachitsulo chokhala ndi silicon.
M'zaka za m'ma 1990, Japan Nisin Steel Co., Ltd. idapanga zida zokutira za zinc-aluminium-magnesium zokhala ndi dzina lazamalonda la ZAM, zomwe kukana kwake kwa dzimbiri ndi nthawi 18 kuposa zokutira zachikhalidwe za zinki, zomwe zimatchedwa m'badwo wachinayi wa dzimbiri. zosagwira zokutira zakuthupi.

Zogulitsa
·Ili ndi kukana kwa dzimbiri bwino komanso moyo wautali wautumiki kuposa pepala wamba lozizira;
·Kumamatira bwino ndi kuwotcherera;
Malo osiyanasiyana alipo: chofufumitsa chachikulu, chofufumitsa chaching'ono, chopanda fulake;
·Zithandizo zosiyanasiyana zapamtunda zitha kugwiritsidwa ntchito pongodutsa, kuthira mafuta, kumaliza, kuteteza chilengedwe, ndi zina;
Kugwiritsa ntchito mankhwala
Hot dip kanasonkhezereka mankhwala chimagwiritsidwa ntchito m'madera ambiri.Ubwino wawo ndikuti amakhala ndi moyo wautali wotsutsana ndi dzimbiri ndipo amatha kutengera malo osiyanasiyana.Nthawi zonse akhala njira yodziwika bwino yothana ndi dzimbiri.Amagwiritsidwa ntchito kwambiri mu nsanja yamagetsi, nsanja yolumikizirana, njanji, chitetezo chamsewu, mzati wanyali wamsewu, zida zam'madzi, zida zomangira zitsulo, zida zothandizira, mafakitale opepuka, etc.
