About our silicone roll industry for future developments: until now, our country has more than 400 production probably cot, but 400 in which it is mostly small workshops around the processing of small factories, small scale of these plants, a single product, the technical level is poor, which is characterized by low prices, convenient delivery, printing rollers only to low-end products supporting the printing press and refurbished, the output value of only a few hundred million. So Cots industry in China is still lagging behind the technological level and production levels. But although China's rubber roller industry still has great development trend, especially the rise of the printing industry have accelerated the development of the rubber roller industry. Many printing companies are required to produce a large number of cot job, let's look at the information on the rubber roller. 1. The heat will accelerate the aging silicone roller heated desulfurization, thermal aging, the surface sticky, softened, or even crack into orange-peel-like. Cots can only be replaced at this time. 2. colloid block out the ink transfer process early colloids dried dry ink film due to its ductility decreased during rolling in, it will make the colloid surface ink film with cracks and damage, resulting in a colloidal off the block occur. The main reason for the occurrence of early drying of the ink is drying agent added to the ink, the ink dry faster printing ink, no ink roller cleaning as required, so that the ink in the long-term use on the rubber roller dry phenomenon occurred. Cots processing temperature is too high, the surface is easy to carbonation, short print phenomenon occurs off the block. Excessive printing pressure adjustment when the machine idling, idling protection if improper or untimely, will accelerate the destruction of the roll body surface. To solve this problem: the occurrence of cot off the block can be replaced resulting print troubleshooting. 3. The glaze surface in the printing process, the ink connection inorganic organic compound, and the fountain solution hydrocolloid, exfoliated filler in paper, paint in the surface layer of the ink roller "bright film ", so that the ink roller surface glass ink transfer performance. The rubber roller surface of the crystalline compound 5. Roller expansion: In addition to the heat of reasons, the main reason is the use of improper cleaning agents, so that colloidal swelling occurred. Solution: Choose the appropriate cleaning agent. (Cot swelling often makes an organic solvent: MEK methyl ketone aldehyde, trichlorethylene, acetone, methane ring, bananas water; swellable organic solvent: alcohol, kerosene, gas oil, roller cleaning agent) 6. Circumferential Streak: In addition to the crystalline compound can cause similar outer circumferential streaks on silica gel ink roller rolls rigid ink dry skin, garbage will scratch soft rubber roller surface during operation to form a circumferential streaks . You must use ink remover to remove dead dry skin ink. 7. The ink fountain roller stick: chrome roll after adsorption enables the ink fountain solution sufficiently isolated, but an excess of dampening fluid, acidic dampening solution is too strong will to increase ink emulsion ink will be as emulsified Back to return to the water fountain roller, the fountain roller can cause adverse fountain ink adsorption, local water minor problems. You must promptly remove the ink fountain roller. While adjusting the size of the amount of fountain solution and its components.
