Zvinhu zvinokanganisa ukobvu hwezinc simbi yegiya yekuputira zvinonyanya: kuumbwa kwesimbi yegiyo yesimbi, kushata kwepamusoro kwesimbi, zvirimo uye kugoverwa kwezvinhu zvinoshanda silicon uye phosphorus mugiyo resimbi, kushushikana kwemukati kwegiyo yesimbi, zviyero zvejometri zvesimbi yekugezesa simbi, uye kupisa-kunyudza galvanizing process yesimbi. Ikozvino yepasirese uye yeChinese inopisa-dip galvanizing zviyero zvakakamurwa kuita zvikamu zvinoenderana nekukora kweplate. Ukobvu hwepakati uye hukobvu hwemunharaunda hweiyo zinc coating inofanirwa kusvika pahukobvu hunoenderana kuti uone maitiro e-anti-corrosion ye zinc coating. Nguva inodiwa kuti uwane kuenzana kwekupisa uye zinc-iron exchange equilibrium yesimbi grating workpieces yehukobvu hwakasiyana yakasiyana, uye ukobvu hwejasi hwakaumbwa hwakasiyanawo. Avhareji yekuvharisa ukobvu muyero ndeye indasitiri yekugadzira ruzivo kukosha kwakavakirwa pane yataurwa pamusoro apa galvanizing mashini, uye ukobvu hwenzvimbo chiitiko chakakosha chinodiwa kuti utarise kusaenzana kugoverwa kwehukobvu hwekuputira zinc uye zvinodikanwa zvekudzivirira ngura kwejasi. Naizvozvo, iyo ISO standard, American ASTM standard, Japanese JS standard uye Chinese standard ine zvishoma zvakasiyana zvinodiwa pakukora kwe zinc coating, izvo zvakafanana. Zvinoenderana nezvinopihwa zvekupisa-dip galvanizing standard GB B 13912-2002 yePeople's Republic of China. Iyo zingi yekuputira zviyero zvezvinopisa-dhipi yakabatiswa simbi yekugadzira zvigadzirwa ndezvizvi: Kune inopisa-dip yakabatiswa simbi gratings ine ukobvu kupfuura kana kuenzana ne6mm, avhareji zingi yekuputira ukobvu pane inopisa-dhipi yakabatiswa simbi grating inofanira kunge yakakura kupfuura 85 microns, uye ukobvu hwemuno hunofanira kunge hwakakura kupfuura 70 microns. Pamagireta esimbi anopisa ane hukasha husingasviki 6mm uye akakura kupfuura 3mm, avhareji yezingi yekuputira ukobvu pane inopisa-dhipi yakabatiswa simbi grating inofanira kunge yakakura kupfuura 70 microns, uye ukobvu hwenzvimbo hunofanira kunge hwakakura kupfuura 55 microns. Kune inopisa-dip galvanized simbi magireti ane ukobvu asingasviki 3mm uye akakura kupfuura 1.5mm, avhareji zinc coating ukobvu pane inopisa-dip galvanized simbi grating inofanira kunge yakakura kupfuura 55 microns, uye ukobvu hwenzvimbo hunofanira kupfuura 45 microns.
Basa uye simba rekupisa-dip galvanizing coating ukobvu
Ukobvu hweiyo inopisa-dip galvanized coating pane simbi grating inosarudza anti-corrosion performance yesimbi grating. Vashandisi vanogona kusarudza zinc coating ukobvu iyo yakakwira kana yakaderera pane yakajairwa. Zvakaoma kuwana yakakora coating muindasitiri kugadzirwa kwematete simbi gratings ane yakatsetseka pamusoro isingasviki 3mm. Uye zvakare, iyo zinc yekuputira ukobvu husina kuenzana nehupamhi hwesimbi grating ndiro inozokanganisa kusimba kwekubatanidza pakati pekupfekedza uye substrate uye kutaridzika kwemhando yekupfeka. Gore rakanyanya gobvu replating rinoita kuti kupfekedzwa kuite kunge kwakakasharara uye kuri nyore kubvisa. Iyo yakapetwa simbi grating haigone kumira kudhumhana panguva yekufambisa uye kuiswa. Kana paine zvimwe zvinoshanda zvinhu silicon uye phosphorous mune mbishi zvinhu zvesimbi grating, zvakare zvakanyanya kuoma kuwana yakatetepa coating mukugadzirwa kwemaindasitiri. Izvi zvinodaro nekuti iyo silicon yemukati musimbi inokanganisa maitiro ekukura kweiyo alloy layer pakati pezingi nesimbi, izvo zvinokonzeresa kuti (, phase zinc-iron alloy layer ikure nekukurumidza uye (kusvika pamusoro pekuputira, zvichikonzera hutsinye uye husina kusimba hwekuputira pamusoro, kugadzira grey coating nekunamira kwakashata. Naizvozvo, sezvakakurukurwa pamusoro apa, pane kusava nechokwadi kwekuoma kwesimbi mukukura kwesimbi. kuwana humwe hukuru hwekuputira mukugadzirwa kwechokwadi kunotsanangurwa mukupisa-dip galvanizing mwero wesimbi grating ndeye empirical kukosha inogadzirwa mushure mehuwandu hwekuedza, uchifunga nezvezvinhu zvakasiyana uye zvinodiwa, uye zvine musoro.
