The drum: grassroots have dusting, cracking, peeling, not dry, make coating bonding bad; Base construction should be carefully operation, maintenance, after being dry at the grass-roots level, put the bottom coating, pu castor after curing, again by the waterproof construction technology of layered coating; Porosity, bubble: material did not make the material mixing way and mixing time mixing evenly; Construction should be used when power, high speed but the blender. Production process of pu castor appear precipitation phenomenon is how to return a responsibility? Pu castor production process note: in case of precipitation phenomenon of a quantity, should stir well before use, so as not to affect quality. Coating become warped edge, the edge of the waterproof layer and partial brush on it, and the grass-roots stripping become warped edge. Main reason is the clean, or dry, closed operation is not careful, the seal is not good, become warped edge bottom coating adhesive power is not strong, etc. So at the grass-roots level to ensure clean, dry, to detailed operation. Pu castor it effectively resolved not to leave his mark on the ground, keep the floor clean and tidy. Conductive castor some precision electronics factory in order not to affect the conductivity of electronic products, then use conductive wheel installation, some factories in order to maintain the good performance of the machine, will be installed anti-static pu castor, used to surrounding the release of electrostatic adsorption, so that we can very good protect electronic components, especially some precision components are destroyed by electrostatic its performance, to protect its precision. Note: due to the pu castor during practical application of static electricity in the main purpose is to eliminate areas, in order to guarantee the quality of products are better; So in the process of conductive castor USES the weight capacity is unfavorable and exorbitant, according to the bearing parameters are provided by the manufacturer of bearing, ensure its conductivity. If carefully you will find on the market all conductive castor or antistatic caster wheel bearing in the same series of castor with have certain gap, this is normal phenomenon. High elastic polyurethane casters PU wheel reasonable production technology can help us to produce high quality high elastic polyurethane casters, and PU material as its main raw material for producing polyurethane casters, appropriate or in-depth understanding is an indispensable part of, so to solve a problem for the castor also need our understanding of it has enough. The generation of static electricity: because any surfaces with electrical conductivity, produces a static magnetic fields. The smaller resistance coefficient, flows through the electric current on the surface of the object, the greater the conductivity, the better, on the contrary, the greater the resistance, through the current on the surface of the object is smaller, conductive performance is poor. It push light, shock absorption, smooth operation, reducing the noise. Pu castor contains no lead, lead is harmful to human body material. It around the electrostatic adsorption, effectively protect the health of the workers. Polyurethane ( PU) Is made up of many isocyanate and polyether polyol or polyester polyols and/or small molecules polyols, chain extender agent such as multivariate amine or water, or crosslinking agent made from raw materials such as polymers. By changing the species and composition of raw material, can greatly change the product configuration and performance, get the final product from soft to hard. Polyurethane casters to the pu castor material understanding proficiency can help to find the problem in time for the production and processing, and make corresponding responses. ​ Pu castor manufacturers on the market conductive castor and antistatic conductive coefficient of castor's cubical in 10 ohm & ndash; — Nine of 10 to the power between ohm, this value is not the higher the better, but the lower the better, so in choosing a castor conductivity this is especially important. Castor has been on the basis of quality castor development, provides the high quality in conventional castor castor can also customize all kinds of special applications. Caster in normal product such as conductive castor, or in special custom castor products shall stick to the principle of high quality caster development. Another reason is basic level processing unclean, do clean up carefully before coating at the grass-roots level, can not have float sand and dust, more should not have hole in the grass-roots, coating layers appear porosity should be dealt with according to the technological requirements, prevent leakage of coating damage; When paint viscosity is too large, the inconvenience for blade coating construction, can add a small amount of special thinner to dilute, in order to reduce the viscosity, addition amount shall not be greater than b is 10%.
