Kumashanyarazi ashyushye yamashanyarazi akoreshwa mumirongo yohereza amashanyarazi, ishyirwa mubikorwa rya hot - uburyo bwo gushyushya ibicuruzwa bigena ubuzima bwa serivisi nibikorwa byumutekano. Iyi ngingo izatanga intangiriro irambuye uhereye kumahame yimikorere, inzira yibanze, ingingo zingenzi zigenzura ubuziranenge, ibyiza byubucuruzi, hamwe nubuziranenge bwubucuruzi bw’amahanga.
Ashyushye - dip galvanizing mubyukuri ni metallurgical bonding reaction. Iyo ubuso - busukuye ingogo yibiti byinjijwe muri zinc yashongeshejwe kuri dogere zigera kuri 450, icyuma (Fe) muri substrate yicyuma na zinc (Zn) muri zinc zashongeshejwe gikomeza gukwirakwira no gukurura ibintu, bigakora urwego -. Uhereye imbere, ibice ni:
Icyuma - Zinc Alloy Layer (Imbere Imbere): Ihujwe mu buryo butaziguye na substrate y'ibyuma, igizwe ahanini na Fe3Zn10 na FeZn7, iruzuye kandi ifite imbaraga zifatika cyane, itanga garanti yibanze yo kurwanya ruswa no kurwanya - gukuramo ibice bya galvanised.
Zinc - Icyuma cya Alloy Layeri (Hagati Hagati): Igizwe na FeZn13, ifite umubyimba uringaniye kandi ikomatanya gukomera no gukomera.
Igice cya Zinc Cyera (Hanze ya Hanze): Gipfukirana igice cyo hanze, kiroroshye kandi kiranyerera, kigakora firime irinda zinc oxyde ikingira hejuru. Ikigeretse kuri ibyo, mugihe habaye ibishushanyo byaho, bitanga ubudahwema kurinda agace kashushanijwe binyuze mubitambo byo gukingira anodic.
Kuri Hot Dip Galvanised Yoke Plate, uburebure bwuzuye bwibice bitatu - byububiko bigomba kugenzurwa cyane kugirango biri hejuru ya 65μm. Kubisabwa - bisabwa, ubunini burashobora kwiyongera kuri 85 mm kugirango uhuze ibyifuzo byumunyu mwinshi hamwe nibidukikije byangirika cyane.
Igikorwa cyo kubyaza umusaruro Amashanyarazi ashyushye agomba gukurikiza inzira isanzwe yo kwitegura - ashyushye - dip galvanizing - nyuma yinyuma - ubugenzuzi. Muri byo, kwiyitirira ni intambwe yingenzi igena ubwiza bwa galvanizing kandi bigira ingaruka ku buryo butaziguye no gufatana hamwe.
Kuvura gutesha agaciro: Koresha imiti igabanya alkaline kugirango ushire kuri dogere 60 - 80 muminota 5 -, cyangwa ukoreshe isuku yo hejuru - kugirango ukureho amavuta ya kashe, amavuta arinda ingese, umukungugu hamwe namavuta yamavuta hejuru yisahani ihuza. Impande zashyizweho kashe ya plaque yingogo hamwe ninkuta zimbere zumwobo wa bolt ni ahantu hakunze gusigara amavuta, bisaba igihe kinini cyo gutera cyangwa gusukurwa na ultrasonic.
Gukaraba amazi no kweza: Kwoza mu kigega cyibanze nicyiciro cya kabiri cyo koza amazi kugirango ukureho ibintu byangiza. Iyi nzira igomba kwemeza ko nta kwegeranya amazi cyangwa ibikoresho bisigaye mu mwobo wa bolt.
Gukuramo aside no gukuramo ingese: Koresha aside ya hydrochlorike mu gutoragura, kwibiza mu cyumba cy'ubushyuhe mu minota 10 - 15 kugira ngo ukureho urugero rwa oxyde, ingese, hamwe na oxyde ya okiside hejuru y’icyuma. Ku gipimo kinini cya okiside, igihe cyo gutoranya gishobora kongerwa mu buryo bukwiye, ariko birasabwa kugenzura cyane kugira ngo wirinde gutoragura cyane, ibyo bikaba bishobora gutuma umuntu atitwara neza kandi bikagabanuka.
Gukaraba amazi no kutabogama: Shira mu kigega cya alkaline itabogamye kugirango uhindure ibintu bya aside irike isigaye, urebe neza ko bitagira aho bibogamiye. Urukuta rw'imbere rw'imyobo ya bolt rugomba kwozwa neza kugirango birinde ibisigisigi bya aside bitera ibisebe murwego rwa galvanis.
Drying and preheating: Dry at 120-150℃ for 10-15 minutes to completely remove surface moisture. The surface must be free of water stains and oxidation; otherwise, the galvanized layer may show signs of blistering or exposure to oxidized material. Defects such as those mentioned above; Zinc immersion: The zinc immersion temperature is strictly controlled at 445-460℃. The immersion time is adjusted according to the thickness of the plate. When the thickness is ≤6mm, the immersion time is 1-2 minutes. When the thickness is >6mm, igihe cyo kwibiza ni iminota 2-3. Kuvura ubukonje: Koresha gukonjesha ikirere cyangwa gukonjesha amazi kugirango ukonje ubushyuhe bwicyumba. Mugihe cyo gukonjesha, irinde kugongana hagati ya Hot Dip Galvanized Yoke Plate kugirango wirinde gushushanya kuri kote.
Ku bicuruzwa byoherezwa mu mahanga bishyushye bya Yoke, inzira yo gukora igomba kuba yujuje ubuziranenge n'ibisabwa kugira ngo isoko rigerweho; bitabaye ibyo, ntibazashobora kwinjira ku isoko. Nkumushinga wumwuga, isosiyete yacu ishyira imbere ubuziranenge bwibicuruzwa; nyamuneka nyamuneka kugura.
