Conveyor belt repair strip instruction for use

Image1. Choosing one piece of conveyor belt repair stirp which is 2-3mm larger than damage area. As damage area is center, drawing out marking line.
Making preparation work for roughening.

Images2. Roughening damage area by using of angle grinder which is with high power and low speed and is equiped with tungsten steel grinding disc.
2.When roughening damage area,we recommend angle grinder RAMIMTECH-L1202 which is with high power and low speed and is equiped with tungsten steel grinding disc.
the value of roughening depth  can't be smaller than the thickness value of repair stirp. For instance, the thickest part of 150mm fabric reinforced repair stirp is 4.6mm, so we need roughen 4.6mm to avoid repair strip being scraped by belt cleaner.

Image3. Using non-flammable cleaning solution to clean roughened area.
3.Clean the roughened area by using cleaning solution SK353 and then wait it dry.

Image4. Pouring hardener UT R40 into cold vulcanizing glue ,and stiring it well at the same time.
4.While waiting cleaning soluiton dry, we can mix cold vulcanizing glue with hardener UT R40 and make two components mix well.

Image5. Brushing the mixture of cold vulcanzing glue SK313 and UT R40 to the whole surface which need repair, and waiting it dry to the degree that do not stick finger back.

Special operation pionits of conveyor belt repair strip.
1.Ramimtech materials must be stored at cool dry ventilated place.
2.Temperation of loading material on conveyor belt under 90 ℃.
3.Please use repair materials with non-flammble lable when do underground repair.
4.Bond repair stirp and repair patch in embedded way to avoid of being scraped by belt cleaner.
5.If the surface for bonding is damp,must make it dry before bonding.
6.Do not burn the surface when roughening,abrasion wheel is not allowed to use,only can use RIT tungsten carbide buffing disc.
7.Use steel brush to clear off dust and rubber scraps,and use RAMIMTECH cleaning solution to clean the surface.
8.Glue mixture:when do seamless jointing and repair of belt ,Ramimtech cold vulcanizing glue Sk313 need to be mixed with hardener by the ratio of 100:4, and be stired evenly.
9.Ramimtech mixtrue must be brushed by mane brush hard and evenly to make SK313 mixture can be infiltrated into rubber surface.
Belt surface need brush two coats Sk313 mixture while the blue CN layer of repair strip be brushed one coat.
All the coats need keep from dust and damp.
10.The drying time of cold vulcanizing glue SK313 mixture depend on air temperature, humidity and absorbent of conveyor belt itself.
The first coat on belt need dry to degree of do not stick finger back and the second to the degree of slightly stick.
While brushing the second coat on belt ,need brush one coat onto CN bonding layer of repair strip at the same time.
11.Ensure both bonding surface are dry and clean.
12.Rolling must be started from center to edge. when the first rolling fix position of repair strip, roll second time to extrude air and make bonding firm.
