What method can remove the black spots on the surface of the pu castor?

Effective method purify industrial spots in the surface of the pu castor industry castor use of unique physical and chemical properties of surface active agent, to reduce the surface tension, the emulsification, solubilization foaming and itself to alkali and hard water, good chemical stability, to improve the effect of thick wall industrial castor oil removal purification, and form a layer of foam on the surface of basic layer, inhibiting alkali fog escape, reduce pollution, improve the operating conditions. What method can remove the black spots on the surface of the pu castor? Cleaning solvent is used to join industrial casters oxide by these droplets of liquid moisture adsorption and dissolution, the formation of new liquid drop rises to the surface, form scum removal after cooling. Industrial casters purification with flux choose low melting point, low density, surface tension and large activity, the industrial pu castor slag has strong adsorption ability of salt. Non-metallic inclusions are clear and dissolved hydrogen, followed by a continuous, so that small nitrogen bubble evenly distributed in the processing of purifying liquid inside have the effect of purification. Stainless steel universal brake caster when pu castor is in a state of rest, need to work to locate the object, and install auxiliary lock parts for castor, is the brake casters. Equipped with brake casters, namely belt brake casters. PU castor brake role trundle brake role, refers to when the caster is in a state of static object of the need to work orientation, installation of accessories for locking casters ( The caster wheel brakes) 。 It is worth noting that the trundle brake general effect on slope without work environment, special request pu castor brake design, please consult factory. Belt brake caster and the classification of the different work environment requirements, the polyurethane caster wheel brake design is also different. Castor plant according to the requirements of customers design, development and batch production of about 300 kinds of belt brake casters, including directional braking casters, wanxiang side brake casters, wanxiang with double brake ( At the same time to lock stents and wheels) , direction of rotation braking casters ( Universal orientation device) And so on. All plastic universal PP casters but in industrial production, domestic industrial caster wheel surface machining quality serious influence anodic oxidation product quality, this contradiction is more and more prominent in the warehouse to prevent the time sometimes turn black, it shows that industrial casters started a little oxidation industrial pu castor after oxidation, can be rubbed out oxide, in the sun, illuminate a few days, can solve the problem of oxidation. Processing industry hard anodized aluminum, the length of the pu castor 3 m for machinery parts, textile, electronics, automotive, communications, cookers, horn sound, printing peripheral parts, LED, solar panels stents oxidation processing industrial casters. Surface treatment before the oxidation of aluminum material composition, purity impact on the quality of industrial casters early for science and technology workers. ( ​ )
