[China Glass Net] The inlet cleaning machine adopts the method of gradually cleaning and recycling the three-stage water quality. Five water tanks and corresponding water receiving trays are arranged in the lower part of the conveying platform to store the cleaning water. Since the water itself is contaminated while cleaning the glass, some polishing agents and the like are gradually deposited in the water storage tank, and it is necessary to periodically perform flushing and cleaning to ensure the water quality is clean.
Smoothness of polishing agent and water spray pipe
The inlet cleaner uses an aqueous solution of aluminum or lanthanum oxide as a polishing agent and is added to the brushing process of the disk brush through a water spray pipe between the upper roller tables. Since the solid aqueous solution polishing agent is used, when the concentration is too large, the nozzle is easily clogged. When the polishing agent nozzle is blocked during use, the concentration of the polishing agent after dilution should be adjusted in time. To clean the polish and spray pipe, follow the steps below.
1 Remove the cleaning machine stop, raise the upper roller path of the washing machine, and turn off the power supply and water supply valve.
2 Loosen the fixing bolts at both ends of the nozzle and remove the nozzle.
3 Use a high-pressure water gun to drive pure water from the inlet of the nozzle into the nozzle to form water pressure, observe the water discharge of each nozzle, and use a paper clip to clear.
4 Clean the nozzle, install it back to the original position, tighten the bolts, and keep the nozzle direction unchanged until it is removed.
Air knife drying area cleaning and adjustment
The cleaning machine is equipped with high-purity water heated (temperature is about 45 °C) in the latter tank, so the water stain attached to the surface of the original glass sheet can be blown away by the high-strength wind of the air knife after entering the drying zone. evaporation. The edge of the air knife edge is at an acute angle to the plane of the original glass film. Each time the air knife is removed or its position is changed, the angle should be measured and kept unchanged.
1 Clean the glass debris, labels, paper jams, etc. in the drying area, and wipe the air knife, roller table and other parts with a clean cotton cloth to ensure clean.
2 Remove the primary filter plate and the secondary filter bag for the fan, and use the compressed air to blow out the dust inside, and check for damage or blockage, and replace it regularly.
3 Use the saw blade to plunge into the air knife edge to check if there are any impurities such as filter bag fibers blocking the knife edge.
Through the production practice of these years, we have realized that as long as the maintenance and maintenance of the inlet cleaning machine are carried out in strict accordance with the above procedures, the cleaning effect of the original glass sheet can be ensured to a large extent under the normal process conditions. The quality of glass products is stable.
Acrylic fibers are synthetic fibers made from a polymer (polyacrylonitrile) with an average molecular weight of -100,000, about 1900 monomer units. For a fiber to be called "acrylic" in the US, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate. DuPont created the first acrylic fibers in 1941 and trademarked them under the name Orlon.[1] It was first developed in the mid-1940s but was not produced in large quantities until the 1950s. Strong and warm, acrylic fiber is often used for sweaters and tracksuits and as linings for boots and gloves, as well as in furnishing fabrics and carpets. It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn.
Modacrylic is a modified acrylic fiber that contains at least 35% and at most 85% acrylonitrile monomer. The comonomers vinyl chloride, vinylidene chloride or vinyl bromide used in modacrylic give the fiber flame retardant properties. End-uses of modacrylic include faux fur, wigs, hair extensions and protective clothing.
