弹性模量是注塑加工过程中比较重要的性能参数,从某种角度来说,是能够抵抗弹性变形能力大小的尺度,下面我们从高低模量材料方面来讲讲注塑加工中弹性模量相关内容吧。
Elastic modulus is an important performance parameter in the process of injection molding. From a certain point of view, it is the scale of the ability to resist elastic deformation. Let's talk about the elastic modulus related content in injection molding from the perspective of high and low modulus materials.
弹性模量是描述固体材料抵抗变形能力的物理量。这包括弹性变形和塑性变形。也就是说,高模量材料更“刚性”并且不太可能弯曲或拉伸。
Elastic modulus is a physical quantity describing the ability of solid material to resist deformation. This includes elastic deformation and plastic deformation. In other words, high modulus materials are more “rigid” and less likely to bend or stretch.
一种易于弯曲或拉伸的低模量材料,这分为两种情况。如果容易弹性变形但不发生塑性变形,则俗称“弹性好”。如果容易塑性变形,一般认为是“软”的。刚性材料不易弯曲变形。一般来说,似乎硬度很高。其实并不是,因为还有实力的问题。
A material of low modulus that is easy to bend or stretch, which falls into two cases. If easy elastic deformation but no plastic deformation, it is commonly known as “good elasticity”. It is generally considered “soft” if it is prone to plastic deformation. Rigid materials do not bend easily. Generally speaking, it seems to be very hard. Well, it's not, because there's also the question of strength.
具有高模量的材料不一定具有高强度。一些脆性材料也可能具有更高的模量。在较小的力范围内,应力-应变曲线非常陡峭。但受力稍大时,立即断裂,没有屈服过程。这存在吗?例如,玻璃是,冰糖是,松香是。模量可能仍然很高,但强度很低。硬度也不高。
Materials with high modulus do not necessarily have high strength. Some brittle materials may also have higher moduli. The stress-strain curve is very steep over a small range of forces. However, when the force is slightly larger, it immediately breaks without yielding process. Does that exist? For example, glass is, rock sugar is, and rosin is. The modulus may still be high, but the strength is low. The hardness is not high.
济南注塑加工人员认为,这里的“高模量”和“低模量”也是相对的名词。高强度和低模量的材料模量很低,可以像橡胶一样容易拉伸,但能有钢丝的强度,比较少见。
Ji 'nan injection molding staff think, here “high modulus” and “low modulus” is a relative term. High strength and low modulus materials have very low modulus and can stretch as easily as rubber, but have the strength of steel wire, which is rare.
