减少磨擦的

Comparing with plate-pressing double facer,it decreases friction between conveying belt and press board,lessens motor power(main motor 55kw fit for WJ1800-2200-2production line),reduuces belt loss.

与压板式双面机相比，避免了传送带及压板之间的滑动磨擦，降低了主电机功率（配WJ180-2200-2瓦线时，主电机功率只有55kw），减少了传送带磨损。

The cash is a business felloe lubricant, there is no enough lubricant, the machine stops an operation because of rubbing, have no enough the business activity of cash is also such, but because the cash belongs to not income a property, so reserve cash of the cost is very expensive, cash's holding to have quantity will reduce its latent income over the company of lowest request, so the cash management is very professional with height meticulous of work.

现金是商业车轮的润滑油，没有足够的润滑油，机器因磨擦而停止运转，没有足够现金的商业活动也是如此，但是由于现金属于非收益性资产，所以保留现金的成本非常昂贵，现金持有量超过最低要求的公司将减少其潜在收益，所以现金管理是非常专业和高度细致的工作。

The object of using ball bearings is to reduce the friction.

使用滚球轴承的目的在于减少磨擦。

Especially it use seal-type joint mode to eliminate periodity pressmark of cardboard.

The plastic go down the hopper smoothly and is gripped by the thread of the screw. It is forced to go toward the direction of the gear end along with the rotation of the screw. A mechanical transferring process is formed. During the running of the plastic from the feed port to gear end, a high pressure is formed in the process of plastic curing due to the gradual decreasing of the thread depth and the resistance of filter gauze, splitter plate and gear end. The high pressure helps to press the raw material and improve its heat conductivity performance and the quick melting of the plastic, at the same time, the gradual increasing pressure can help the gas which is among material particles exhausted from the air holes.

在压力升高的同时，塑料一方面被外部加热，另一方面塑料本身在压缩、剪切、搅拌的运动过程中，由于内磨擦力也产生了大量的热，在外力和内力的联合作用下，塑料温度逐渐增高，其物理状态也经历了玻璃态--高弹态--粘流态的变化，一般地说来，在加料段中主要是玻璃态，在螺杆螺纹逐渐减少的中间部分压缩段中，物料主要处于高弹状态，同时也逐渐的熔融，而物料到压缩段后部和化段作用处于粘流态了，这时我们称塑料已完全塑化了，由螺杆推力作用将塑化的塑料定压定量的从机头中挤出。

Explanation: It is good for the outdoor sport and leisure activities. 3Layer fabric: surface layer with TEFLON is flexible and anti-greasy dirt; mid-layer is waterproof, windproof and moisture permeability; lining use fleece to keep warm and ventilate. The lining seam is sewed by mesh that reduces friction, and it is benefit in sport. An elastic rope is on the bottom. The pocket is on the chest with special technology which is waterproof. Side pocket uses mesh that can reduce the cloth weight
