彈性模量是注塑加工過(guò)程中比較重要的性能參數(shù)，從某種角度來(lái)說(shuō)，是能夠抵抗彈性變形能力大小的尺度，下面我們從高低模量材料方面來(lái)講講注塑加工中彈性模量相關(guān)內(nèi)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.
彈性模量是描述固體材料抵抗變形能力的物理量。這包括彈性變形和塑性變形。也就是說(shuō)，高模量材料更“剛性”并且不太可能彎曲或拉伸。
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.
一種易于彎曲或拉伸的低模量材料，這分為兩種情況。如果容易彈性變形但不發(fā)生塑性變形，則俗稱(chēng)“彈性好”。如果容易塑性變形，一般認(rèn)為是“軟”的。剛性材料不易彎曲變形。一般來(lái)說(shuō)，似乎硬度很高。其實(shí)并不是，因?yàn)檫€有實(shí)力的問(wèn)題。
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強(qiáng)度。一些脆性材料也可能具有更高的模量。在較小的力范圍內(nèi)，應(yīng)力-應(yīng)變曲線非常陡峭。但受力稍大時(shí)，立即斷裂，沒(méi)有屈服過(guò)程。這存在嗎？例如，玻璃是，冰糖是，松香是。模量可能仍然很高，但強(qiáng)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.
濟(jì)南注塑加工人員認(rèn)為，這里的“高模量”和“低模量”也是相對(duì)的名詞。高強(qiáng)度和低模量的材料模量很低，可以像橡膠一樣容易拉伸，但能有鋼絲的強(qiáng)度，比較少見(jiàn)。
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.
