BD707 small particle ceramic bead filling repair compound wear abrasion resistant epoxy coatings used in the vibrating centrifuge protecting.
Our company (Xiangyang City Hundred Shield Coating Material Co.,Ltd) procreative BD707 wear resistant small particle adhesive/coating
is used in the vibrating centrifuge of coal preparation plant,become its preferred materials.It is understood that vibrating centrifuge is
widely used in coal carbon and sea salt dehydration,the maximum yield can reach 500 tons solid phased particles per hour.
If you want to achieve the automated filling and discharging of mine used centrifuge,automatic control of coal preparation plant,
in the design of coal preparation plant,can use the computer.Its purpose is that make the moisture of coal surface separate from
the surface of coal by taking advantage of centrifugal force’s effect,make the materials after dehydrating discharge into the discharge
port.Sieve basket is one of the important components in a centrifuge.Sieve basket has two kinds,named horizontal vibrating centrifuge
and vertical vibrating centrifuge.
Horizontal vibrating centrifuge can be divided into the buffer system,transmission system, lubrication system and the engine body parts.
So-called transmission system,one is the transmission of centrifugal rotary motion,the other is the transmission of reciprocating vibration
along axial direction on sieve basket.Among them,the main motor rotation will produce centrifugal rotary motion,deliver to the sieve basket
through the pulleys,leather belt and bearing etc.Pairs of cam rotary swing motion will produce vibration inertia force,pass on to the screen
basket to form axial reciprocating motion through the different shapes of rubber spring.While vibrating centrifuge is for dehydration through
the centrifuge,and move through the vibration inertia force.
Due to the large processing quantity of vibrating centrifuge,the abrasion of the bottom discharge outlet is relatively larger,
and the price of Xiangyang City Hundred Shield Coating Material Co.,Ltd procreative BD707 wear resistant small particle coating
is very cheap,and the wear resistant performance is good,so the BD707 small particle abrasion resistance coatings become the preferred
material of coal preparation plant vibrating centrifuge.
How to use about BD707 wear resistant small particle coating:
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 weight ratio or volume ratio 4:1,make A and B two components mix uniformly,
and use it up within 30 min.Generally it’s while construction and configuration.Every time the most configuration quantity
is not more than 1.5Kg,too much adhesive is solidified too fast,hasn’t been used up until the adhesive has partial solidified and
can’t be used.According to the actual temperature,configuration can be properly a little more in winter and 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 BD707 small particle wear resistant coating is 2-8mm,the most thickness can be 30mm,
make the mixed-up material be coating on the pending-repair part layer by layer,the first layer should be compacted,make it fully infiltrates
with the substrates,repair the surface to be smooth after the coating is coated on the suitable size,if it has high surface requirements,
can make the BD426 corrosion resistant coating be coating on the surface as the topcoat,this material can’t do machining,
should pay attention to controlling the coating thickness to avoid appearing interference phenomenon in the assembly.
4. Curing:Cure for 24 hours at the temperature of 25℃ before using,(If can heat it up to the temperature of 60-80℃ and keep
this temperature for 2 hours,in this way,can improve 30% comprehensive performance) If the temperature is low,
should heat it up or prolong curing time to promote the curing.General construction in winter,can use iodine tungsten lamp to
do irradiation heating with 40cm distance from the coating.
