Description
Technical Field
The invention relates to a coating rubber material of a clean rubber roller for offset printing.
Background
Factors that affect the normal operation of the printing process and the quality of the printed product during the printing process are many, such as paper, ink, printing equipment, process operations, and the like. Wherein because the printing plate is dirty because of paper dust, paper hair to and the china ink skin causes, influence the matter that printing quality and printing efficiency account for than very high, wherein specific reason has:
1. paper factor
The paper is mainly composed of plant fibers, fillers, sizing materials and the like, and the properties of the prepared paper are different due to different raw materials. The common paper mostly adopts stalk fibers, the surface of the paper is uneven and porous, talcum powder is used for filling, or kaolin and the like are used for surface coating, so that the flatness, smoothness, glossiness and strength of the paper surface are different, wherein two indexes of tightness and tensile strength are easy to crack under the action of pressure, ink viscosity and viscous force generated by surface moisture of rubber cloth in the printing process, the phenomena of hair falling and powder falling can be generated, the failure of the ink skin is caused, the shutdown times are more, the stability of the color can not be ensured, and the failure of burr-shaped spots or solid whitening on the printed matter is caused.
2. Ink factor
(1) The quality problem of the ink is as follows: in general, the ink has a long leaving time, and is not sealed well, and ink skin is likely to be generated. The ink skin fault caused by the ink appears in a large number of continuous ink skins in the printing production, even if the machine is stopped for processing each time, the ink skins still appear immediately after the machine is started, no reduced trace exists, and the ink skins still do not reduce after the ink roller is cleaned and the ink is printed again;
(2) the movable part has a large area and is solid or has heavy ink color: generally, ink skins often appear when printing large-area solid parts and parts with heavy ink colors, but the printing machine cannot be stopped for processing the ink skins, if the printing machine stops for a long version, the printing speed cannot be increased, and the yield is influenced certainly; and the number of times of short edition live stopping is large, the ink color of the whole batch of live parts is difficult to keep consistent, so that the live part quality is obviously reduced.
3. Technological factors
(1) Too high printing pressure: the printing pressure must be strictly controlled during the printing process, otherwise the ink skin is very easily generated. Because the surface of the paper is seriously peeled off due to the excessive printing pressure, the matter peeled off from the paper is quickly transferred to a printing plate and mixed with ink to generate a large amount of ink skin.
(2) The humiture of the printing workshop does not reach the standard: the temperature of the printing workshop should be controlled at 20-24 ℃, and the humidity should be controlled at 60% -70%. When the temperature and humidity are low in the printing process (especially in autumn and winter in the north and under the condition that an air conditioner and a humidifier are lacked in a workshop), the ink has high viscosity and poor flowability, and ink skin is easy to generate. However, when the room temperature is higher than 26 ℃, the surface of the ink in the ink fountain becomes easier to dry due to the heat generated by the operation of the machine, and if the ink in the ink fountain is not stirred within 1 hour, ink skins are generated on the surface of the ink fountain, and the ink skins are likely to be transferred to paper along with the rotation of the ink roller, so that the printing is inconvenient. Therefore, in summer when the temperature is high, the temperature of the printing shop is lowered.
(3) The press down time is too long: if the down time is long (generally, half an hour or more than one hour) due to reasons such as reasons or equipment failure, the ink skin is easy to fail in the printing process. Because most printing enterprises use quick-drying ink at present, the ink is easy to dry on an ink roller, and ink skins are easy to generate when the printing machine is restarted for printing after being stopped for a long time.
4. Tooling factors:
poor paper cutting: if the cutter is blunt, paper pile side paper hair can be more after the paper cuts, arouses the china ink skin trouble during printing easily. The continuous paper conveying is performed at the position where the paper flies, the leading edge of each paper is in contact with the surface of the previous paper, and if the paper is not cut well, the paper edge is broken and the paper is broken, the paper powder at the leading edge of the next paper falls on the surface of the previous paper and is brought into a printing machine to be adhered to a rubber blanket and then is transferred to a printing plate through the rubber blanket to form an ink skin. Because each piece of paper is dusted and fluffed, the ink skin fault caused by the reason can be caused as soon as the machine is started, and the machine needs to be stopped for processing, so that continuous printing cannot be finished at all.
5. Human factor
(1) Adding old ink doped with ink skin into the ink fountain when a worker changes duty;
(2) during the printing process, ink skin is generated due to the fact that workers do not stir ink frequently, especially in summer;
(3) after printing the movable piece using offset paper, when the movable piece with large ink amount needs to be changed, ink is printed again without cleaning the ink roller; because offset paper is easy to lose powder and fall off hair, the paper powder and the paper hair can be stuck on an ink roller, and a large amount of ink skin can be generated after the offset paper is replaced;
(4) during printing, the burnt-out paper caused by improper paper feeding can not be taken out in time and is stuck on a rubber blanket and wound into an ink roller, and finally, a large amount of ink skin is generated during printing due to the fact that paper sheets are not completely treated and the ink roller is not completely cleaned;
(5) the ink roller is not cleaned completely when the previous group goes to work, so that a little ink remains on the ink roller, and after the ink is dried for a long time, ink skins are easy to appear in the next group during printing.
Disclosure of Invention
The invention aims to solve the problems that the printing plate is dirty due to paper dust, paper feathers and ink skin, the water and ink transfer of a printing machine is influenced, and the printed product is dirty or white spots occur. Forced stopping of the wiping plate can lose a lot of effective printing time, and waste of printing time and unwarranted increase of printing cost are caused.
The cleaning rubber roll coated by the rubber material is used between a printing plate and an ink roller, namely the cleaning rubber roll for cleaning paper powder, paper wool and ink skin in a printing unit with a water path connected with an ink path, and the framework material of the rubber material is the blended rubber of ethylene propylene diene monomer J-4045 and chlorosulfonated polyethylene rubber, so that the prepared rubber material has oil resistance, water resistance, corrosion resistance and stable electrical property, and simultaneously has a thermoplastic elastomer with good adhesion property, and the surface micro-adhesion of the rubber roll is realized. The cleaning rubber roller can automatically clean impurities such as paper powder, paper fluff and ink scraps which are transmitted to a printing plate by paper in the process of printing, and transmit the impurities to the water channel, so that the printing becomes clean and smooth, the quality of printed products is improved, the printing cost is saved, and the working efficiency is improved.
