drive shaft wearing resistant epoxy compound repair ceramic paste coating

BD215 anti abrasion wearing resistant compound epoxy coating repair agent
used in transmission drive shaft repairing and protecting:

Drive transmission shaft is a high rorate speed,little bearing rotating body,domestic commonly using the way of repairing welding,inlaying shaft sleeve,
making pocking mark etc. based on the transmission shaft abrasion,but when the material of shaft is No.45 steel(thermal refining),if only use the
surfacing welding processing,it will produce welding internal stress,in the case of heavy load or high speed operation,it may appear the phenomenon
of crack and even fracture in the place of shaft shoulder,if use the stress relieving for annealing,it is hard to operate,and the process cycle is long,
the cost of overhaul is high,when the material of shaft is HT200,using cast iron welding is also not ideal,some companies with higher maintenance
technology will use brush plating,laser welding,micro arc welding and even cold welding etc.These maintenance technology often needs higher
requirements and expensive cost.

these are not common in the enterprise of Europe and the United States,Japan and South Korea,the developed countries generally use macromolecule
composite technology and Nano technology,macromolecule technology can do site operation,it can promote maintenance efficiency effectively,
and reduce maintenance costs and repair density.

domestic commonly use BD215 abrasion wearing resistant compound repair agent which produced by Xiangyang City Hundred Shield Coating
Material Co.,Ltd at present.BD215 anti abrasion wearing resistant repair compound is the high performance wear abrasion resistant,corrosion resistant
polymeric ceramic material which compounded by various high performance anti abrasion wear resistant,anti corrosion resistant material(such as:
ceramic,silicon carbide,carborundum,titanium alloy) and modified toughening heat resistant resin.Used in accurately repairing the friction and
abrasion failure axle journal,axle hole and bearing block

BD215 anti wear abrasion resistant repair agent epoxy compound not only has the strength and hardness of metal required,but also has the deformability
(variable relationship) which metal doesn’t have,through “mold repairing”,”the corresponding relations between parts” “machining”,
can ensure maximum the dimensional coordination between repairing parts and mating part,at the same time,make use of the material itself has
comprehensive advantage of compressive strength,bending strength and percentage of elongtation etc.It can absorb the impact of the external force
effectively,greatly defuse and counteract the radial impact force of bearing on the shaft,and avoid the possibility of appearing gap,also avoid the
equipment second time abrasion which caused by enlarged interspace.

How to use of BD215 anti abrasion wearing resistant repair compound ceramic epoxy coating:
1.Surface treatment: Do the roughening treatment on the surface of pending-repair part,if the condition is allowed,can turn out about 1.5mm depth thread,
then clean it by cleaning agent and dry it by airing.

2.Preparation: According to the mass ratio A:B=6:1 or volume ratio A:B=4:1,make the A and B two components mix uniformly,and use it up within the
specified operation time limit.

3.Coating:Make the well mixed material be coating on the pending-repair parts layer by layer,the first layer should be compacted,make it infiltrate fully
with the substrates.If the following working procedure needs machining,should keep out appropriate machining allowance.

4.Curing:It can do machining after curing for 8 hours at the temperature of 25-30 degree,it can be put into using after curng for 24 hours,if the temperature
is below 15 degree,should heat it up or prolong curing time to promote the curing,generally heat it up to the temperature of 80 degree and keep this
temperature for 2 hours to complete the curing with iodine tungsten lamp or hair dryer.

Industrial protective coating application in various mining industry equipment

Typical application of repairing wear equipment from thermal power,cement,coal washing and mineral processing
