coil steel covering and coating process line

BackgroundWith the high speed development of Chinese economy,the metal packing container is thriving,the demand of the tin plate as the main packing raw material rises sharply.According to the data from China Packing Technology Association,the contradiction between supply and demand of our domestic market is getting striving.As for that,the price of the tin plate is rising gradually,which rises to 86.5%.Under this circumstance,the production costs is transferred,one is that the price rises to the lower level,the other one is that using the advanced technology to lower the cost.To rise the price,the enterprises is hard to manage;It is the only way for us to adopt the advanced technology to meet the unprecedented challenges.Under the current market circumstance,it is more important to adopt the advanced technology to transform the traditional producing technology and enterprises to gain the market share. DefinitionLaminated Steel or Coated Steel is composition material which makes the color printing plastics film composite the cold rolling steel plate through fusion method and viscosity method,it can replace the metal printing on the tinplate and chromed steel.CharacteristicsThe processing flow of the tin plate processing line changes the traditional printing steel technology which symbolized printing,baking the steel plate one by one,the muiticolored plastics film directly hot-press or bond the rinsied roll of the sheet material,then cut-to-length as requirements,the producing process is automatic controlled,the printing and laminating can be done in a time,it achieves the industrialized manufacture of container sheet.The laminated steel consists of Polymer resin membrane and steel plate,the resin includes:polyester (PET),Polypropylene(PP),etc.The steel plate includes:tin plate ,chromium iron, plain sheet, galvanized iron,etc.The laminated steel is combined of resin and steel,so it has the advantages as follows:1.The appearance is bright and clean,smooth,good decorated,well handfeel2.high wear resistance,rust resistance3.strong chemistry stability,anti-corrosion,aging resistance4.the capillaries of the surface has little function5. Good formability,it can be deep punching6.the conglutination to the paint has little function

Compared with the traditional tin plate offset printing,the technology not only improves the physiochemical stability,decoration of the packing container,but also it has the striking advantageous in production.

Fast speed,high efficiency,it is triple times than traditional printing steel.The film printer taken color printing film technology can print 8~10 sets in one time,it can reach 100~200m/min,the max width is 1.2m,the film viscose is 40-80m/min,the two surface can compound at the same time.A workteam can produce 30T,while the workteam used Fuji double color press only can produce 10T,the working efficiency has raised triple times.

Low energy consumption,low cost,Hypothermia energy conservation 70%As the laminating and printing can be finished with high speed in one time,the technology requires the temperature reaches about 60°C,which is one third of tin plate flat hose.It takes the polyester film instead of varnish, white pearly membrane instead of white coating,the material consumption cost of per square is reduced 30%,meanwhile the inventory period can be reduced 50%.What is more important that the tin plate film technology adopts coiled sheet,it can omit the seaming and roll cutting,the material availability can rise 4.5% ,all of these are played an important role in cost reduction of cans industries.

Little exhaust gas discharge,be environment-friendly1.As the polyester film is instead of varnish, white pearly membrane is instead of white coating,it reduced the exhaust gas discharge in dissolvant.2.The printing sheet technology need to 3~6 processes of drying,it will bring out exhaust gas discharge while using kerosene.

Easy operation,convenient maintenanceDuring the tin plate printing process,the techniques and working process are all controlled by experienced operators.While the laminated steel production techniques and equipments are all controlled automatically,it is easy operation,convenient maintenance and to master the production and maintenance technology.ApplicationsCompared with the tin plate printing technique,the laminated steel has the advantages of performance,production cost,material cost,environment protection and energy consumption.The laminated steel has a good market share when it puts into the market,it is widely used in packing,home appliance,construction decoration and other industries.The canning laminated steelTechnology is advanced and durable,it reduces its production cost while rises its economic benefits.Nowadays,the tin plate printing is widely used,the revolution of this technology must create more economic and social benefits to the plate printing , packing container and canning industry.
