& nbsp; & nbsp; HY907 Conveyor Belt Joint Adhesive Application

  & nbsp; & nbsp; A conveyor belt is a rubber fiber or metal composite product used in belt conveyors to carry and transport materials, or a plastic fabric composite product. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemical engineering, and steel where the conveying distance is short and the conveying volume is small. Belt conveyors are widely used in agriculture, industrial and mining enterprises, and transportation industries to transport various solid block and powder materials or finished items. The conveyor belt can transport continuously, efficiently, and with a large inclination angle. The conveyor belt is safe to operate, easy to use, easy to maintain, and has low transportation costs. It can also shorten the transportation distance, reduce project costs, and save manpower and material resources& nbsp;

  & nbsp; & nbsp; Wear forms of conveyor belts during operation



  & nbsp; & nbsp; The main reason for replacing conveyor belts is wear, which is generally divided into the following three forms:< br />


  & nbsp; & nbsp; The wear at the vulcanized joint of a conveyor belt is usually caused by the material of the conveyor belt itself having a higher wear resistance than the adhesive layer at the vulcanized joint, or by thermal vulcanization quality issues, resulting in local wear of the vulcanized joint adhesive layer, exposing the steel wire core or nylon core, and posing a serious threat to the strength of the vulcanized joint between conveyor belts< br />


  & nbsp; & nbsp; The conveyor belt is worn at the skirt area



  & nbsp; & nbsp; Due to improper adjustment of the skirt plate of the conveyor belt guide device or poor design of the guide skirt plate, the skirt plate will wear down the conveyor belt during operation, causing severe wear on the adhesive layer on both sides of the conveyor belt. The entire tape will expose the steel rope core or nylon core in the longitudinal running direction. Once the steel rope core lifts up, it is easy to wrap around the roller, causing the steel belt to loosen or the tape to tear< br />


  & nbsp; & nbsp; The wear of the middle part of the conveyor belt is caused by the impact of material dropping. Due to the relatively fixed dropping point of the funnel, the wear of the part of the conveyor belt that bears the impact is intensified, resulting in severe local wear along the running direction of the conveyor belt, as well as the detachment of the exposed steel rope core or the tearing of the conveyor belt. For nylon tape, it causes a decrease in the strength of the middle part due to the presence of 3 load-bearing rollers 4. Due to the forward tilt angle, under the action of the centering force of the carrier roller, there will be a phenomenon of "" during the operation of the tape; Stacked tape” The dangerous phenomenon.

  & nbsp; & nbsp; Repair process of HY907 adhesive for rubber conveyor belt



  & nbsp; & nbsp; Traditional repair methods for rubber conveyor belts


  & nbsp; & nbsp; Hot vulcanization bonding connection method: Its advantage is high bonding strength, which can reach 90% of the original tape; Flat fitting with no impact; Relatively good flexibility. The disadvantage is that high heat source requirements are required during vulcanization, and the equipment is bulky, which is not conducive to handling; The process is complex, takes a long time, and is greatly affected by environmental temperature and humidity. And the vulcanized part of the joint is prone to peeling and cracking< br />


  & nbsp; & nbsp; Mechanical connection method: Its advantages are simple operation, fast speed, and low cost. The disadvantage is that the strength of the tape connection is weakened, only 35% of the original tape- 45%, prone to fatigue damage, short service life, uneven joints, severe impact damage to the rollers during operation, and accompanied by material leakage problems< br />

  & nbsp; & nbsp; Repair case of rubber conveyor belt damage



  & nbsp; & nbsp; Case 1: On site repair of rubber belt damage



  & nbsp; & nbsp; The depth of the damaged size is about 25px, and the width varies between 1.5-50pxAccording to calculations, 2kg of material can repair a length of approximately 6 meters< br />


  & nbsp; & nbsp; Operation process:< br />


  & nbsp;& nbsp; & nbsp; 1. Polish the damaged inner and outer surfaces of the rubber belt with polishing pads and steel wire wheels< br />


  & nbsp;& nbsp; & nbsp; 2. After cleaning the debris with a brush, use a surface cleaner to wipe the cleaned surface clean< br />


  & nbsp;& nbsp; & nbsp; 3. Brush and stir NPT-150 conveyor belt adhesive evenly on the wiped inner and outer surfaces< br />


  & nbsp;& nbsp; & nbsp; 4. Use a hot air gun to scrape and flatten both sides from the inside out< br />


  & nbsp;& nbsp; & nbsp; 5. Afterwards, use a hot air gun to melt the material and fill all the pits, and use a hot air gun scraper to compact and level them< br />


  & nbsp;& nbsp; & nbsp; 6. After the repair is completed, clean the material on the edges of the high points and grooves. Suggest running at light load after 2 hours, and running at full load after 8 hours
