Galvanized square tube yog dav siv nyob rau hauv lub tsev steel qauv, automotive manufacturing, mechanical manufacturing, choj qauv vim zoo heev corrosion kuj, sib sib zog nqus ua molding, xim, thiab weldability, thiab zoo nto zoo thiab zoo txhua yam khoom. , Thawv keel, nkoj tsim thiab lwm yam kev lag luam.
Galvanizing square tube raj ua haujlwm yog lub hauv paus ntsiab lus ntawm electrolytic, thiab txheej txheej hlau los yog hlau yog tso rau ntawm cov khoom los ntawm cov txheej txheem electrolytic ntawm cov hlau ions los hloov lub cev thiab tshuaj lom neeg ntawm cov khoom nto. Thaum kawg Tsis tas li ntawd, nws tuaj yeem pleev xim raws li cov kev cai tshwj xeeb ntawm cov khoom tshwj xeeb, thiab nws tuaj yeem coated nrog qee cov txheej txheem tshwj xeeb, xws li lub teeb lub zog thiab electromagnetic txheej, thiab lwm yam, kom nws tuaj yeem nthuav dav hauv daim ntawv thov. ntawm galvanized square tube.
Cov khoom specifications ntawm galvanized raj raj yog: square tube: 20 × 20 × 1.3 - 500 × 500 × 16mm; Rectangular tube: 20 × 30 × 1 3 - 400 × 600 × 16mm.
Galvanized torque yeeb nkab ua cov txheej txheem electroplating feem ntau muaj cov txheej txheem ua ntej, plating thiab tom qab-plating kev kho mob. Qhov zoo ntawm txheej plating yog nyob ntawm cov txheej txheem electroplating ntawm cov khoom, thiab cov txheej txheem electroplating cuam tshuam los ntawm ntau yam. 6 yam tseem ceeb tau muab sau tseg raws li nram no:
1. Zinc cov ntsiab lus: qhov siab dua qhov purity ntawm zinc thaiv, qhov nqaim ntawm qhov ci ntawm nws lub teeb, qhov yooj yim dua kom tau txais cov txheej txheem ntawm lub tsheb, thiab cov ntsiab lus hlau hauv txheej yuav qis dua; Thaum lub purity ntawm zinc thaiv yog tsawg dhau lawm, nws qhov ci ci yuav siv sij hawm ntev dua kom ncav cuag cov zinc txheej tuab, uas yuav ua rau cov ntsiab lus hlau ntau dua hauv txheej galvanized.
2. Sodium hydroxide: Sodium hydroxide muaj ob txoj hauv kev rau cov tshuaj tiv thaiv. Thaum nws cov ntsiab lus siab dhau lawm, scorching yog nquag tshwm sim thaum lub sijhawm ua haujlwm kub; thiab thaum nws cov ntsiab lus tsawg dhau, cov tshuaj muaj peev xwm dispersion tsis zoo, uas yuav txo cov zinc txheej. qhov zoo ntawm.
3. Cov ntsiab lus hlau: Thaum cov ntsiab lus hlau siab dhau lawm, cov hlau hauv cov txheej txheej plating yuav sib xws, uas yuav ua rau cov khoom passivation zaj duab xis tsis txaus thiab ci; thaum cov ntsiab lus hlau tsawg dhau lawm, nws yuav ua rau cov ntsiab lus ntawm cov hlau tsis tshua muaj nyob rau hauv cov txheej txheem galvanized, txo lub rooj tsav tsheb mus rau lub rooj tsav tsheb Cortency kuj yuav ua rau lub npoo ntawm lub tsheb phaj yog txiv ntseej.
4. Cov ntsiab lus: Tam sim no siv ntau glitter uas muaj ZF-100A thiab ZF-100B sib tov. Cov concentration ntawm yav dhau los yog siab dhau lawm yuav txhim khu lub brittleness ntawm lub plating txheej. Ob qho phenomenon.
5. Kub: Kub kub heev thaum lub sij hawm electroplating yuav ua rau cov decentralized tov txo, cov hlau cov ntsiab lus nyob rau hauv lub plating txheej nce, thiab passivation yog tsis sib xws; Thaum cov tshuaj tiv thaiv kub qis dhau lawm, qhov chaw siab-tam sim no yuav raug hlawv yooj yim, plating yog crispy thiab sedimentary qeeb ceev.
6. Cathode txav ceev: Thaum lub sij hawm electroplating txheej txheem, lub cathode yuav tsum nyob rau hauv lub xeev ntawm kev txav. Yog hais tias lub zog txav ceev heev, plating ntawm qhov chaw siab tam sim no nyob rau hauv cov txheej txheem electroplating yuav ntxhib; thiab lub zog txav qeeb dhau. Qhov tseem ceeb
Lub raj galvanized yog siv los ua electroplating hlau. Cov electrode yog siv los ua hluav taws xob Zn2+ nyob rau hauv cov tshuaj, thiab tom qab ntawd cov nplaim hluav taws xob galvanized square torque yeeb nkab tau muab tso rau hauv cov txheej txheem thiab ntom zinc hlau. Piv nrog rau lwm yam hlau, zinc belongs rau ib tug poj niam txiv neej hlau, uas yog ib qho yooj yim rau yaj nyob rau hauv acid thiab yuav soluble nyob rau hauv alkali. Nws yooj yim dua rau hluav taws xob hlau ions hauv cov tshuaj. Thaum lub sij hawm ua cov galvanized suab raj, xyuam xim rau cov saum toj no yam los tsim high-zoo tsim nyog galvanized square tube khoom.
