DCCD company has been committed to researching and promoting the latest technology for conveyor system maintenance, and has proprietary room temperature (cold) vulcanization bonding technology and specialized rubber sheet material products. It can effectively solve common maintenance problems such as belt wear, belt deviation, belt tearing, belt breakage, local belt aging, belt cuts, and belt delamination caused by drum slippage. Effectively prevent the occurrence of conveyor belt deviation accidents. DCCD cold vulcanization products greatly increase the running time of the belt and reduce the cost of downtime maintenance.

● DCCD rubber sheet is pre vulcanized rubber on a large specialized flat vulcanizing machine, with the maximum vulcanization pressure (50kg/cm2) and high density of the rubber sheet.
● The formula of DCCD rubber sheet comes from the best experimental results, and the sulfur content used in the vulcanization reaction under high pressure is extremely moderate, and high-quality anti-aging agents are used. It will not age or harden during use, and has excellent elasticity.
● DCCD cold vulcanization encapsulation uses DCCD metal treatment agent as a transition layer between the drum metal and rubber plate bonding, effectively enhancing the bonding effect (up to 12N/mm)
● DCCD is different from traditional cold bonding, as it features the company’s unique rubber CN layer and DCCD super strong adhesive. During the encapsulation process, it can be vulcanized and bonded at room temperature, which involves both physical bonding and chemical reaction processes. Its bonding strength is significantly higher than that of traditional cold bonding and hot vulcanization casting rubber.
● DCCD cold vulcanization encapsulation technology can be used to encapsulate the drum on the belt conveyor at any time, reducing the cost of dismantling and transporting the drum, saving time, reducing the labor intensity of workers, and eliminating the loss of other components of the belt conveyor when dismantling the drum.
It can meet the technical service of non dismantling state of belt conveyor system or on-site roller coating construction.
Suitable for various specifications and models of ultra wear-resistant coating technology construction.
According to the manual operation of 800×1000 drum, the normal operation time from scraping glue to polishing and pasting glue should not exceed 16 hours (excluding loosening hammer, tensioning belt, and equipment recovery time).
Firstly, confirm the speed of the conveyor belt, the on-site environment, and the load-bearing situation. Choose the thickness of the ceramic adhesive plate, measure the length and diameter of the adhesive roller, calculate the material consumption, and cut the material. Using ceramic drum wrapping material can enhance the self-cleaning of the drum and prevent conveyor belt deviation.
Calipers, tape measures, folding rulers, marking powder line ropes, rubber marking pens, Danka screwdrivers, layering knives, layering peeling hooks, and cleaning brushes for measuring thickness;
Safety helmet, work clothes, steel helmet shoes, gloves, flashlight, goggles, earplugs, work notebook, work permit.
1. Shovel glue: Clean all the existing film on the drum completely.
2. Grinding: Use tungsten steel grinding discs and fiber grinding discs (16K-28K) to smooth the surface of the drum;
3. Cleaning: Use specialized DCCD high-efficiency cleaning agent to clean the surface of the drum twice. Maintain a ventilated environment during the cleaning process;
4. Brush metal primer: evenly apply DCCD metal treatment agent DCCD, requiring sufficient drying;
5. Brush cold vulcanized adhesive: Apply DCCD cold bonding agent DCCD evenly twice, and ensure it is fully dried.
6. Treat the surface of TRS wear-resistant rubber sheet and apply DCCD cold adhesive DCCD evenly, keeping it clean.
7. Adhesive board pasting: Stick the wear-resistant rubber board coated with cold adhesive DCCD on the surface of the drum, align it with the marking, compact it, and exhaust the air;
8. Joint treatment: Use DCCD sealing adhesive or DCCD quick repair adhesive at the joint of the rubber plate. The joint treatment angle is about 45 degrees, which is suitable and neat.
9. DCCD cold vulcanization ceramic roller coating is completed.
Smooth the roller coating and restore the working surface function of the roller;
There is no adhesion on the surface of the drum, and there is no expansion of belt wear;
There is no occurrence of wear and tear, no further damage to the belt frame material, and no safety hazards;
After reinstalling the cleaner to clean the belt, the load on the belt is greatly reduced;
The belt runs stably without any shaking or deviation.
Check the usage date of DCCD cold vulcanized products and the CN uncured layer of ceramic rubber sheets.
Bubble treatment: puncture and release small bubbles, cut atmospheric bubbles into square blocks for treatment.
The drum after being coated with glue needs to be tested by professional personnel before it can be put into operation.
Drum shaking issue: 1. Check if the machine components are complete first, 2. Belt issue, 3. Check if the drum wrapping is standardized.
Adhesive peeling problem: 1. Adhesive failure, 2. Unclean, 3. Metal primer not applied, 4. Wear resistant adhesive plate too thin, 5. High belt speed, 6. Drum not rotating, 7. Joint treatment not done, water present?, 8 has oil pollution.
