(3) can produce by pattern how wide in variety.The semiproduct production and the stamp of rolling process are independently finished at calender or printing machine.The time of semiproduct production and printing, speed, batch what do not influence output, speed and the product yield of foaming furnace.Single batch of economic production quantity has only 2000 square metres, relatively is fit to the many kinds of exploitation, multi-color, and the compliance of product is wider.
(4) can make the best use of everything.The leftover pieces that produce in production semiproduct, the finished product process, defective products etc. can reclaim at calender at any time to be produced once more, and no waste of material does not have the rubbish of production.
The shortcoming of calendering technology:
The flattening and the dimensional stability of product are relatively poor, and be relatively more suitable civilian, is difficult to adapt to commercial large-scale place and high-grade place ground decoration.
Be coated with the general introduction of scraping technology---be coated with the method for scraping and be manufacturing process with product and all be coated with and scrape at one, the technology of finishing on the foaming streamline, that is: at batch plant used raw material is mixed with pasty state, be coated with kerf with the foliated glass cloth as base material, scrape basic unit by being coated with, gel, cooling, be coated with again after the upset and scrape, gel, cooling, be coated with again and scrape foaming layer, gel, cooling, be coated with again and scrape back of the body seal gel, cooling, print after the upset, and then be coated with and scrape the laggard foaming furnace of surface layer and foam, cooling, batch the technology of producing the PVC coiled material floor, owing to all finish being coated with on the kerf, therefore be called for short the method for scraping that is coated with.
Be coated with the advantage of scraping technology:
(1) flattening of product and dimensional stability are good, are fit to large commercial place and high-grade place ground decoration.
Time cost was relatively low when (2) single pattern was produced in enormous quantities.
Be coated with the shortcoming of scraping technology:
(1) hardness of product and intensity are influenced by Processes and apparatus, can't satisfy as the requirement of the big place of visitors flowrate such as airport, supermarket, workshop to product hardness.
(2) cost of raw material is higher.Since be coated with and scrape the employed PVC of production technology and stick with paste resin, higher by about 40% than suspension method PVC price.Because the cost height, product competitiveness is relatively poor relatively, is the maximum puzzlement of this explained hereafter product of employing producer.
(3) be coated with and scrape the technology device-restrictive of originally experiencing, must adopt new raw material to produce, leftover pieces that produced and defective products can't recyclings, cause bigger material waste.
(4) being coated with what scrape process using is omnidistance pipelining mode, and pattern of every adjustment or product structure all are to finish on streamline, loss that causes and waste greatly, cost is higher.Therefore, only be fit to few pattern and produce in enormous quantities, general single batch of proper production economic magnitude is 20000m
2More than, so the producer that adopts this kind technology, product category is more single, and pattern is less.
