1.The classifications of conveyor belts
Conveyor belts are widely used in cement, coking, metallurgy, chemical, steel and other industries where the conveying distance is short and the conveying volume is small.High-quality rubber conveyor belts have physical properties such as high strength, high wear resistance, low elongation and heat resistance. Specific performance can be divided into the following three categories.
Classification by use:
Oil-proof conveyor belt, Non-slip conveyor belt, Climbing conveyor belt, Anti-acid and alkali conveyor belt.
Heat-resistant conveyor belt,Cold-proof conveyor belt,Flameproof conveyor belt, Anti-corrosion conveyor belt, Moisture-proof conveyor belt, Anti-low temperature conveyor belt, Oil resistant conveyor belt, High temperature resistant conveyor belt, Acid and alkali resistant conveyor belt, Flame retardant conveyor belt.
Classification according to conveyor belt material:
PVC conveyor belt, Polyethylene conveyor belt, Plastic chain conveyor belt, Modular mesh conveyor belt, Polypropylene conveyor belt,nylon conveyor belt,stainless steel conveyor belt.
Heat resistance:
Heat-resistant conveyor belt: TI type resistance is not more than 100°C, T2 type is not more than 125°C, T3 type is not more than 150°C
High temperature resistant conveyor belt: the temperature resistance capacity is not more than 200°C
Burn-resistant conveyor belt (metal mesh conveyor belt): temperature resistance 200-500°C
2.Conveyor belt manufacturing standards
Technical standard:
Ordinary type implements GB/T9770-2001 standard.
Cold-resistant type, ozone-resistant type, and flame-retardant type implement the G2539-93 standard.
Acid and alkali resistant type, heat resistant type and anti-tear type implement HG/T3646-1999 standard.
The flame-retardant type implements the MT668-1997 standard.
Connector standard:
Vulcanizer:The vulcanizer for vulcanized joints must be a qualified product that has passed the appraisal and has complete certificates
Gum:Glue includes cover glue (surface glue), core glue and glue.
In order to ensure the quality of vulcanized joints, the rubber material should generally be selected from the rubber material specified by the original belt factory.
If you use rubber from other factories, you must make a vulcanized joint in advance and send it to an authoritative department for tensile strength testing. It can be used only after it meets the requirements.
3.How to ensure the product quality of rubber conveyor belt?
Step 1:Advance equipment to guarantee quality from the details
Roller gluing machine can apply glue on both sides of the fabric at one time, reducing the loss of fabric strength rubber in the process.
The forming tension is even between different plies,which can avoid wrinkled fabric and guarantee an even thickness of belt core.
Step 2:Finished belts inspection
We have an inspection team to inspect the surface and dimension of each conveyor belt. If any problem on belt surface, we will repair at once in our factory.
Step 3:Technical data test
We have a lab to test all raw materials and rubber compound.For each roll of conveyor belt,the lab will test the following features, and issue Quality Test Report.
Test items:
General performance: Through-thickness tensile strength, alcohol blowtorch combustion, drum combustion, propane roadway combustion, antistatic, oxygen index, grooving, straightness, wire bonding strength, joint life, joint strength, reference force elongation, cord stickiness bonding strength, bonding strength between cloth and top glue, fatigue life, low temperature resistance, etc.
Mechanical properties: Hardness, tensile properties, tear properties, compression properties, bending properties, impact properties, friction properties, fatigue resistance, friction coefficient and wear properties, tensile shear strength, peel strength, tear-off strength, rubber and single steel wire Adhesive strength, vulcanized rubber or thermoplastic rubber and fabric adhesive strength, etc.
Combustion performance:Vertical combustion, horizontal combustion, smoke density, limiting oxygen index, flame spread rate, etc.
Electrical properties: Surface resistance, surface resistivity, volume resistance, volume resistivity, breakdown voltage, dielectric strength, dielectric loss, electrostatic properties, etc.
Weather resistance test:Aging test (ultraviolet, xenon lamp, carbon arc lamp, ozone), liquid resistance test such as oil, temperature shock, etc.
