Galvanized sheet (Galvanized sheet) zvinoreva ndiro yesimbi yakakora ine zingi rakaiswa pamusoro.Kupisa-dip galvanizing inzira yehupfumi uye inonzwisisika yekurwisa ngura iyo inowanzosarudzwa.Inenge hafu yezinc inogadzirwa munyika yose inoshandiswa mukuita uku.
Galvanized sheet ndeyekudzivirira ngura pamusoro peiyo gobvu simbi ndiro uye kuwedzera hupenyu hwayo hwesevhisi.Kumusoro kwendiro yesimbi yakakora yakafukidzwa nesimbi ye zinc.Rudzi urwu rwe zinc-coated gobvu simbi ndiro inonzi galvanized sheet.
Zvinoenderana nekugadzirwa uye nzira dzekugadzirisa, inogona kukamurwa muzvikamu zvinotevera:
① Kupisa-kunyudza kwakabatiswa gobvu simbi ndiro.Iyo inotonhora-yakaputirwa simbi yesimbi inopindirwa mune yakanyungudutswa zinc bath, kuitira kuti pamusoro peiyo inotonhorera-yakaputirwa simbi yesimbi inonamatira neyakagadzika zinc.Panguva ino, kiyi ndeye kushandisa inoenderera inopisa-dip galvanizing process yekugadzira, ndiko kuti, ndiro gobvu resimbi mundiro rinoramba richinyudzwa mutangi replating rine zinc yakanyungudutswa kugadzira pepa remarara;
②Pepa rezviyo rakasimbiswa.Iri rudzi rwesimbi gobvu ndiro inogadzirwawo nenzira inopisa yekunyudza, asi pakarepo mushure mekunge yabuda mutangi, inopisa kusvika pa500 ° C kuishandura kuita aluminium alloy epurasitiki firimu rezinc nesimbi.Rudzi urwu rwemarata ane galvanized adhesion of architectural coatings uye welding yemagetsi;
③ Electro-galvanized sheet.Kugadzirwa kwerudzi urwu rwemarata emagetsi ne electroplating kune yakanakisa maitiro ekuita.Zvisinei, kupfekedza kwacho kwakatetepa, uye kupikisa kwehutu hakuna kunaka seyaya inopisa-dip galvanized sheet;
④Rimwe divi uye maviri-mativi maviri galvanized sheet.Single uye kaviri-sided galvanized sheet, kureva, zvinhu zvinopisa-dip galvanized kune rimwe divi.Panyaya yemagetsi welding, kupfapfaidza, anti-ngura kurapwa, kugadzirwa uye kugadzirisa, nezvimwewo, ine yakasimba kuchinjika pane kaviri-sided galvanized sheet.Kuti ubvise chirema chezinc isina kuvharwa pamativi ese, kune rumwe rudzi rwerata rakaputirwa nechromatographic zinc kune rimwe divi, kureva, galvanized sheet ine musiyano pamativi ese;
⑤ Aluminium alloy, composite galvanized sheet.Yakagadzirwa nezingi uye zvimwe zvinhu zvesimbi zvakaita sealuminium, lead, zingi, nezvimwewo kugadzira aruminiyamu alloys kana kunyange composite makobvu simbi ndiro.Iri rudzi rwendiro yakakora yesimbi ine zvese zvinoshamisa anti-ngura kurapwa maitiro uye yakanakisa kupfapfaidza maitiro;
Pamusoro pezvishanu zviri pamusoro apa, kune zvakare mavara ane mavara galvanized sheet, hembe inodhinda yakapfapfaidza galvanized sheet, polyethylene laminated galvanized sheet uye zvichingodaro.Asi panguva ino, inonyanya kuzivikanwa ichiri kupisa-dip galvanized sheet.
Stainless simbi ndiro izita rezita restainless acid-resistant simbi, inoshingirira kune isina kusimba zvinhu zvakaita segasi, chiutsi, mvura, kana mamakisi esimbi ane zvimiro zvesimbi inonzi stainless steel plate;nepo zvinonyungudutsa zvinonyunguduka (asidhi, alkali, munyu uye mamwe organic kemikari corrosion) ) etched simbi mamakisi anonzi masimbi anodzivirira acid.
Nekuda kwekusiyana kwekuumbwa kwezviviri izvi, kushorwa kwavo kwekuora kwakasiyana.Kazhinji, mahwendefa esimbi asina simbi haawanzo shingirira mukuora kwezvinonyungudutsa, nepo masimbi anodzivirira acid kazhinji ane zvimiro zvesimbi.Izwi rekuti "stainless simbi ndiro" haringorevi chete rudzi rwesimbi isina tsvina, asi rinoratidzawo marudzi anopfuura zana emarata esimbi asina tsvina anogadzirwa mumaindasitiri.Imwe neimwe ndiro yesimbi isina tsvina yakagadziridzwa uye yakagadzirwa ichave neakanakisa maitiro echinangwa chayo chakakosha.Chinokosha chekubudirira ndechekuona yekutanga kushandiswa kwekutanga, uye ipapo iyo yakakodzera simbi giredhi.Iko kune kazhinji chete matanhatu simbi mamakisi ane chekuita nechinangwa chikuru chechimiro chekuvaka.Vese vane 17-22% chromium, uye yakanaka simbi mamakisi zvakare ane nickel.Kuwedzera molybdenum kunowedzera kunatsiridza kuora kwemhepo uye inoshingirira zvakanyanya kumhepo ine fluoride.
Stainless simbi ndiro inoreva simbi inoshingirira kumarara asina kusimba segasi, chiutsi, uye mvura, uye organic kemikari inoparadza zvinhu zvakaita seasidhi, alkali, nemunyu, inozivikanwawo sesimbi isina simbi inodzivirira acid.Mumashandisirwo chaiwo, simbi inoshingirira kuzvinhu zvinoodza zvisina simba inowanzonzi simbi isina kusimba, uye simbi inoshingirira mukuora inonyungudutsa inonzi simbi inodzivirira acid.Nekuda kwemusiyano wekuumbwa pakati pezviviri izvi, yekutanga haisati yave inoshingirira mukuora kwezvinonyungudutsa, nepo iyo yekupedzisira kazhinji isina tsvina.Kudzivirirwa kwekuora kwesimbi isina tsvina kunogara mualuminium alloy zvinhu zviri musimbi.
