NCR production techniques of the past few years the country has successfully developed a resin-modified alkyl salicylate zinc reagent, while maintaining excellent speed and color based on the color optical density greatly improved lightfastness carbon procurement, this lightfastness zinc alkyl salicylate resin has been applied in a number of manufacturers. Carbonless CF paper of the main component of the adhesive coating has a PVA, styrene-butadiene latex, such as modified starch. Although PVC maximum bond strength carbon company, is 1.5-2 times styrene-butadiene latex, starch 3-4 times, but because of PVA water-sensitive, film strength (NCR will affect the color effect), cost high, susceptible acid, alkali influencing, rheology deterioration problems at high speeds without using a separate shear. SBR has good bond strength and water resistance, easy to get a high smoothness and gloss coated paper, carbon paper factory after calendered, but SBR poor water retention, pH values ??below will produce precipitation and other shortcomings 6:00 not alone. Despite their low bond strength of starch, but because it does not form a film as well as better water retention and widely used. NCR adhesive coating usually consists of three kinds of adhesives (PVA, styrene-butadiene latex, modified starch) with the use of both high strength makes the adhesive system also contains an open surface state, to minimize gum Effect of viscosity on the film-forming agent is a color effect, while the presence of the starch during drying helps to maintain the water content of the coating. NCR scrupulous CB coating operation in the coating process to avoid the presence of the line pressure, in order to ensure the quality of CFB both sides of the paper, should be re-coated surface coated CF CB surface. Operatives coating head should always pay attention to the material circumstances, adjust the feed roll and the backing roll gap and left side of the tailgate appropriate location. When the material is more stable can be properly adjusted to the smaller side, in order to improve the rate of a paper, when the material is unstable to get some slightly larger side regulation, in order to avoid splashing color material impact on product quality. Also one should always clean up the plot material carbon coating on both sides of the head of each roll to prevent splashing material. Must pay attention to the quality of CF paper, does not allow the use of serious splash material CF CFB paper coated paper, in order to avoid unnecessary losses.
