MOR-1 Type Oil-Resistant Conveyor Belts: Enhanced Performance for Demanding Applications

What Sets MOR-1 Apart?

Although the exact specifications of MOR-1 may vary slightly between manufacturers, it generally represents an enhancement over the standard MOR type. Think of it as a "MOR-plus" – offering the same core benefits of moderate oil resistance but with improvements in specific areas, such as:

• Slightly Higher Oil Resistance: While still classified as "moderately oil resistant," MOR-1 belts might utilize a higher acrylonitrile content in their nitrile rubber (NBR) cover compound or feature a more advanced cover formulation to provide a slightly better resistance to oil absorption and swelling.

• Enhanced Durability: MOR-1 belts may boast improved abrasion resistance, making them suitable for handling materials that are both oily and rough on the belt surface. They might have a thicker cover within the typical 1.5mm to 8.0mm range on the working surface, offering extra protection.

• Improved Heat Resistance or Other Properties: Some MOR-1 belts may be designed with better heat resistance or improved performance in other areas, such as tear resistance or low-temperature flexibility. 

Where are MOR-1 Belts the Right Choice?

These belts are a good fit for industries where standard MOR belts are suitable, but where a little extra performance is desired or needed. Here are some examples:

1. Recycling Plants (Handling Oily Plastics):

• Scenario: Sorting and conveying mixed plastic waste, some of which may be contaminated with oils or lubricants.

• Customer Concern: "We need a belt that can handle the oil, but we also deal with sharp edges on some of the plastic scrap. Will a standard MOR belt be durable enough?"

• Answer: The MOR-1, with its likely enhanced abrasion resistance and a cover thickness potentially on the higher end of the 1.5mm to 8.0mm range, would be a better choice here. Its nitrile rubber cover is specifically designed to resist oil, and the added durability helps withstand the sharp edges. The core, made of materials like polyester or nylon (with nylon offering up to 700 N/mm per layer in tensile strength), provides the necessary strength.

2. Food Processing (Handling Oilseeds):

• Scenario: Conveying oil-rich seeds like corn and rapeseed where oil content is high and consistent.

• Customer Concern: "We process a lot of oily seeds. Will a standard MOR belt offer enough protection, or will we be replacing it frequently?"

• Answer: A MOR-1 belt, potentially with its slightly higher oil resistance due to a refined nitrile rubber (NBR) formula or higher acrylonitrile content, could offer a longer service life in this scenario. Its ability to minimize oil absorption (low volume change rate) and maintain strength (high strength retention) is crucial here.

3. Concrete Plants (Exposure to Release Agents):

• Scenario: Conveying materials in a concrete plant where oil-based release agents are used on forms and equipment.

• Customer Concern: "The release agents we use can be pretty harsh on belts. Do we need a high oil resistance belt, or will a MOR-1 suffice?"

• Answer: A MOR-1 is often a good choice here. While not for constant, heavy oil exposure, its enhanced nitrile rubber formulation can handle intermittent contact with release agents better than a standard MOR. The specific choice depends on the concentration and frequency of exposure. The wear should be ≤ 1.20 cm³, tensile strength ≥ 12.0 MPa, and elongation at break ≤ 400%.

Key Considerations When Choosing MOR-1:

• Specific Application: What materials are you conveying? What's the level of oil exposure? Are there other factors like abrasion or heat?

• Manufacturer Specifications: Always check the manufacturer's data sheet for the exact specifications of their MOR-1 belts, as these can vary. Look for details on oil resistance testing, cover thickness (typically 1.5mm to 8.0mm on the working surface), core material strength (e.g., nylon at up to 700 N/mm per layer), and any other enhanced properties.

• Cost-Benefit Analysis: MOR-1 belts may have a slightly higher upfront cost than standard MOR belts, but the extended lifespan and improved performance can often justify the investment.

Questions and Answers:

• Q: What is the maximum speed these belts can run at?

• A: The speed of these belts should generally not exceed 2.5 m/s.

• Q: How often should these belts be inspected?

• A: Regular inspections are crucial, especially in corrosive environments. Look for signs of wear on the cover, any damage, and address any issues promptly. If the belt becomes misaligned, take measures to correct it. If there is any damage, make repairs immediately.

• Q: How should these belts be stored?

• A: They should be stored rolled in a clean, dry place, away from direct sunlight, rain, and chemicals. Maintain a temperature between 18-40°C and relative humidity between 50-80%. Rotate them every quarter.

Conclusion:

MOR-1 Type Oil-Resistant Conveyor Belts offer a valuable upgrade for applications that demand more than standard moderate oil resistance. They provide enhanced durability, potentially better oil resistance, and may include other improved properties. By carefully considering your specific needs and consulting manufacturer specifications, you can determine if MOR-1 is the right choice to keep your operations running smoothly and efficiently in challenging, oily environments. They are a smart investment for businesses that need a robust solution for handling moderately oily materials with an extra level of protection and performance.
