Okay, so you've probably heard of conveyor belts, those moving bands that carry stuff around in factories, airports, and all sorts of places. But what's a "MOR Type Oil-Resistant Conveyor Belt"? It sounds complicated, but it's actually a pretty straightforward concept. Let's break it down.
Imagine this: You're working in a place that deals with oily materials – maybe it's a food processing plant handling corn or rapeseed, a recycling center sorting greasy waste, or a factory using oil-based lubricants. Regular conveyor belts just don't cut it in these situations. The oil seeps into the rubber, making it swell up, lose its shape, and eventually fall apart. That's a recipe for a messy, expensive headache.
That's where MOR Type Oil-Resistant Conveyor Belts come in.
"MOR" stands for Moderately Oil Resistant. Think of these belts as having a special shield – a nitrile rubber (NBR) cover – that protects them from the damaging effects of oil. This nitrile rubber is special because it has a high acrylonitrile content. 
Let's get to some basic questions:
Q: What exactly does "moderately oil-resistant" mean?
A: It means the belt can handle a good amount of oil exposure without getting damaged. It's not for extremely high oil concentrations, but it's perfect for many common industrial applications. It's a middle ground between standard belts and those designed for very heavy oil exposure (which probably have other designations).
Q: What's so special about nitrile rubber?
A: Nitrile rubber, especially the kind with high acrylonitrile content, is known for its ability to resist oil absorption. This means the belt won't swell up as much (low volume change rate), and it will maintain its strength (high strength retention).
Q: How strong are these belts?
A: They're strong! They usually have a core made of nylon or polyester canvas. Nylon, for instance, can provide a tensile strength of up to 700 N/mm per layer. That's strong enough to handle heavy loads. The specific strength will depend on the number of plies (layers) and the specific materials used.
Q: How thick is the protective cover?
A: The cover thickness varies, but it's usually between 1.5mm and 8.0mm on the top (working) surface, and 1.5mm to 4.5mm on the bottom. A thicker cover generally means better protection.
Q: Can these belts handle heat as well?
A: While their main job is oil resistance, the specific temperature range depends on the manufacturer. It's always best to check the specifications for the particular belt you're considering.
Q: What about the belt's size?
A: You've got options. These belts come in widths ranging from a narrow 100mm to a massive 3000mm. They also have between 1 and 10 plies (layers of fabric) for added strength.
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: What are the technical indicators of these belts?
A: The wear is ≤ 1.20 cm³, tensile strength is ≥ 12.0 MPa, and elongation at break is ≤ 400%.
Q: How are these belts different from MR, MOR-1, and MOR-A belts?
A: MR likely means Mildly Oil Resistant, so it offers less protection than MOR. MOR-1 and MOR-A are probably variations on the MOR type, perhaps with slight improvements or changes for specific uses, but their exact meaning isn't standardized across the industry.
In a Nutshell:
MOR Type Oil-Resistant Conveyor Belts are a great choice if you need a conveyor belt that can handle oily materials without quickly degrading. They offer a good balance of oil resistance, strength, and affordability. They're like the reliable workhorses for many industries that deal with moderate oil exposure.
