There are two types of impurities on the upper surface: one is silver wool and solid impurities, the Other is a variety of oil, wax sensation and so on. If these impurities are not removed in time, the phenomenon of blooming, pinholes, and lacquer removal will occur during the post-treatment process. The role of cleaning is to remove these impurities and lay the foundation for the next process. In general, when cleaning shoes, the following points should be noted:
1, pay attention to the protection of soles and skins, common soles are PU, rubber, PVC, TPR, of which the first two materials resistant to cleaning agents performance is good, not easy to bite, but the surface paint is easy to destroy; the latter two kinds of substrate easily Cleaner bites. The protection of Lippi is to prevent the detergent from flowing into the skin (especially sandals).
2. Cleansers have certain irritation to the skin, and direct contact can make the skin dry easily. It is recommended to use protective gloves.
3, detergents are mostly volatile solvents. Containers containing cleaning agents should not be too large. When they are decommissioned, they should be tightly closed to avoid unnecessary waste and dust pollution. Attention should be paid to the ventilation in the air and avoid the air. Too much residual solvent to ensure that the volume concentration of solvent in the air is below the explosion limit.
4, according to different leather materials, choose a different degree of strong detergent, it is best to do a small test. Light skin cleanser should be used for light skin and double skin to prevent discoloration caused by cleaning. For black skins, they should be treated differently depending on the nature of the leather coating; for aniline-finished leather, strong cleansers should be used to wash the coating to achieve a more clear after-treatment effect; For leather, a moderately strong or mild detergent can be used according to the degree of repair, to avoid stickiness when cleaning and to expose the original defects of the repaired leather. The principle of the selection of detergents; as far as possible under the premise of not destroying the leather, use a strong point cleaner. Light color natural rejection, wipe color leather to use mild detergent to prevent discoloration, can not be used to clean the mercury pen.
5, the intensity of cleaning should be uniform, can not be neglected lightly, otherwise it will lead to color difference and poor gloss, is not conducive to the operation of the next step.
6, the detergent can not be left on the surface too much, too much, the skin, skin hole suction more difficult to dry, easy to spray after the light, paint, gloss is not good, at the same time, will leave traces of dry and Spots, or damage to the soles and soles of the glue, causing degumming.
7. Cleaners are mostly flammable and explosive materials. Pay attention to ventilation and fire prevention when using them, keep away from ovens and fire sources, avoid overheating and sunlight, use appropriate fire extinguishers such as dry powder, carbon dioxide, and foam fire extinguishers when they catch fire. Do not use direct fire extinguishers with fire. Do not use fire to extinguish directly. When the detergent in the container undergoes gas expansion due to thermal expansion, the lid should be opened and pressure relief should be promptly released.
8, there is a phenomenon of oily skin, more than a few clean, to prevent paint and whitish, flowers. When only one is cleaned, the oil is washed out by the solvent, and the solvent is washed out. After the solvent evaporates, the grease remains on the surface. At this time, the light is sprayed and it is easy to get a flower. Therefore, clean the road more until no grease remains on the surface.
9, after cleaning is dry, it is recommended to use horsetail wheel (brush) to remove the remaining angstroms and rags, the intensity should be moderate, speed 1000 rev / min. Some plants use ponytails after the extender, depending on the viscosity of the extender. · The old shoes at home are like this to transform big spikes · Old shoes don't stupidly throw away so that the shoes "open" Put a physical insurance on your shoes · How to clean the matte surface of the shoes? · Breathable, antibacterial, deodorizing socks with it to avoid off shoes ·Sports shoes's little tail actually has these 3 functions you certainly don't ·High-heeled shoes audio sound? 4 coups to ease you learn a few ·How to choose shoes during pregnancy?
