BD7057 ball mill repair special anti abrasion wearing resistant ceramic epoxy coating

Product usage of BD7057 ball mill repair special paste ceramic compound abrasion resistant epoxy resin coatings:
BD7057 ball mill special wear resistant material is the abrasion resistant,corrosion resistant polymer ceramic material which is compounded by high performance wear resistant ceramic particle and modified toughening resin,used for the
filling up of ball mill cylinder,end cover and other substrate by slurry erosion wear,also used for repairing of ball mill center axis inner wall and exit erosion wear or the preparation of wear resistant protective coating on the surface of machine part.

Performance features:
1. Wear resistance is equivalent to the level of imported ceramic particle epoxy coating;
2. Excellent abrasion and corrosion resistance;
3. High bonding strength with metal substrate;
4. Convenient construction,there is no very high technical requirements for construction personnel.

How to use
1.Surface treatment: Do coarsening treatment on the pending repair part,grinding with angle grinder or sand blasting etc, the surface after coarsening treatment should be cleaned,the surface after this treatment should be the one coarsening,
dry and fresh substrates,should be no greasy dirt and dust.

2.Preparation:According to the specified mixing weight ratio,make A and B two components mix uniformly,and use it up within 30 min.Generally it’s while construction and configuration.Each time the largest preparation quantity should be
not more than 1.5 Kg,otherwise too much coating is solidified too fast,hasn’t been used up until partial adhesive has cured and can’t be used.According to the actual temperature,configuration can be properly a little more in winter,proper less in summer.
If the temperature is too low,can properly heat up the A component to reduce viscosity for easy to configure.

3. Coating:The suitable coating thickness of BD7057 coating is 4cm to 15mm,the largest thickness can be 30mm.Make the mixed prepared materials be coating on the pending repair part layer by layer,the first layer should be compacted,
make it infiltrate fully with the substrates.Repair the surface to be smooth after the coating is coated in the suitable size.

4. Curing:It can be put into using after curing for 24 hours at room temperature 25℃,If the temperature is below 10℃,should heat up the mixed materials or prolong curing time to promote the curing.General construction in winter,
can use iodine tungsten lamp do irradiation heating with 40cm distance from the coating.(if you could heat it up to the temperature of about 80℃ and keep this temperature for 2 hours after initial curing,it can improve 30% combination
property of the coating)
