1、PU输送带与PVC输送带的材质
1. Material of Pu conveyor belt and PVC conveyor belt
PU输送带：材质就是PU材质，可以用在很多工业上，而用于食品工业方面一般都是用PU输送带，也就是叫做食品输送带，符合食品卫生标准可与食品直接接触。
Pu conveyor belt: the material is PU material, which can be used in many industries. However, Pu conveyor belt is generally used in the food industry, which is also called food conveyor belt. It meets the food hygiene standards and can be in direct contact with food.
PVC输送带：材质就是聚氯乙烯（PVC），它构成为聚酯纤维布和聚氯乙烯胶构成，工作温度为-10°+80°，可以用于很多工业上。
PVC conveyor belt: material is polyvinyl chloride (PVC), it is composed of polyester fiber cloth and polyvinyl chloride glue, working temperature is - 10 & deg; to + 80 & deg;, can be used in many industries.
2、PVC输送带的特性
2. Characteristics of PVC conveyor belt
质轻、易加工、耐磨损、价廉、光泽感好、易保养，但透气性、耐滑性差，在低温状态下会变硬使得屈折性差，并容易产生断裂。PVC颜色丰富，适合夏天配时装用。
Light weight, easy processing, wear resistance, low price, good gloss, easy maintenance, but poor air permeability, skid resistance, in the low temperature state will harden, making poor bending, and prone to fracture. PVC color rich, suitable for summer with fashion.
3、PU输送带的特性
3. Characteristics of Pu conveyor belt
擎川输送带厂家介绍PU又称再生皮，再生革。它的特点是质轻、耐磨损不滑、耐寒、耐化学品，但价贵、易撕裂、机械强度差，抗撕裂强度差。PU色彩较少。主要为黑色或啡色。质地较软，适合用于做休闲包，亦不高易脱色。
Pu is also called regenerated leather. It is characterized by light weight, wear resistance, cold resistance and chemical resistance, but it is expensive, easy to tear, poor mechanical strength and tear resistance. Pu color is less. It is mainly black or brown. Soft texture, suitable for leisure bag, price is not high, easy to decolorize.
而这两种输送带都有一个共通点，那就是正反面要使用不同的材质，反面的材质要尽量减少摩擦，正面的需要有摩擦。底纱需要可以非常有效的防止输送带发生变形，延长输送带的使用寿命，加大输送带底层的耐磨性，并且非常好的减少摩擦。
And these two kinds of conveyor belts have one thing in common, that is, the front and back should use different materials, the material on the back should try to reduce friction, and the material on the front should have friction. The bottom yarn needs to be able to effectively prevent the deformation of the conveyor belt, extend the service life of the conveyor belt, increase the wear resistance of the bottom layer of the conveyor belt, and reduce the friction very well.
4、区分PVC输送带和PU输送带的方法
4. How to distinguish PVC conveyor belt from Pu conveyor belt
①看表面，这两种输送带看起来很相似，PU输送带比PVC更硬；
① Look at the surface, the two conveyor belts look very similar, Pu conveyor belt is harder than PVC;
②闻气味，两种输送带都有一定的气味，只是PVC输送带的气味更重，带有嗅味，而PU没有，那是淡淡的气味。
② Smell, two kinds of conveyor belt have a certain smell, but the smell of PVC conveyor belt is heavier, with smell, but Pu does not, it is a light smell.
