生物降解颗粒TPEE的四种包胶方式

TPEE具有橡胶的弹性和工程塑料的强度；软段赋予它弹性，使它象橡胶；硬段赋予它加工性能，使它象塑料；与橡胶相比，它具有更好的加工性能和更长的使用寿命；与工程料相比，同样具有强度高的特点，而柔韧性和动态力学性能更好。那么生物降解颗粒TPEE的包胶方式是怎样的呢？

TPEE has the elasticity of rubber and the strength of engineering plastics; The soft segment gives it elasticity, making it like rubber; The hard segment gives it processability, making it like plastic; Compared with rubber, it has better processability and longer service life; Compared with engineering materials, it also has the characteristics of high strength, better flexibility and dynamic mechanical properties. So what is the coating method of biodegradable particles TPEE?

真正的封装

True packaging

TPEE与塑料、金属等材料通过化学作用，如分子渗透、极性基团或类似氢键的反应连接和键合等化学作用，在两种材料的结合界面形成牢固的焊接或结合，没有任何机械和物理作用。无需粘合剂，可通过注塑成型直接与金属粘合。

TPEE and plastics, metals and other materials form firm welding or bonding at the bonding interface of the two materials through chemical actions, such as molecular penetration, polar group or reaction connection and bonding similar to hydrogen bond, without any mechanical and physical effects. Without adhesive, it can be directly bonded to metal by injection molding.

在这种加工方式中，一般将TPEE和金属件封装为一个整体，TPE的硬度尽可能高（70~80A及以上），这样才能达到一定的封装效果，因为TPE的封装和金属没有真正意义上的附着力（化学和分子水平），金属被TPE的强度完全包裹。此外，金属零件表面有凹槽和孔（如螺母和刀架）。

In this processing method, TPEE and metal parts are generally packaged as a whole, and the hardness of TPE is as high as possible (70~80a and above), so as to achieve a certain packaging effect, because TPE packaging and metal have no real adhesion (chemical and molecular level), and the metal is completely wrapped by the strength of TPE. In addition, there are grooves and holes on the surface of metal parts (such as nuts and tool holders).

假封装

False encapsulation

TPEE与硬质材料（塑料、金属或其他材料）的物理和机械结合纯粹是通过孔和凹槽等卡扣的方式，而不是简单地依靠两种材料的化学结合。两种材料的界面在分子水平上没有直接渗透，也没有极性基团或氢键等反应性键（范德华力）。用粘合剂粘上。

The physical and mechanical combination of TPEE and hard materials (plastic, metal or other materials) is purely through holes and grooves, rather than simply relying on the chemical combination of the two materials. The interface between the two materials has no direct penetration at the molecular level, and there are no polar groups or hydrogen bonds and other reactive bonds (van der Waals force). Apply with adhesive.、

有时对于一些特殊的产品，橡胶只是部分覆盖了金属件的相应位置，不利于TPEE与金属件的牢固结合。在要涂敷的金属表面上涂一层粘合剂是一种常见的想法。但实际上，由于TPEE与橡胶的成型工艺不同，对橡胶件与金属件的粘合牢固性有着重要的影响。粘合剂类型的选择对于此类金属产品的涂层关重要。

Sometimes for some special products, the rubber only partially covers the corresponding positions of metal parts, which is not conducive to the firm combination of TPEE and metal parts. It is a common idea to apply a layer of adhesive to the metal surface to be coated. But in fact, TPEE has an important influence on the adhesion between rubber parts and metal parts due to the different molding process between TPEE and rubber. The choice of adhesive type is very important for the coating of such metal products.

整体封装

Integral package

生物降解颗粒厂家认为，整体包封相当于注塑一个TPEE塑料件，其中硬件产品是在没有化学键合的情况下进行包封的，所以包封还是可行的。一般硬度较高、硬度在80A以上的TPEE都可以镀，但是镀后的五金件要整体镀，如果只镀一部分镀层是很难做到的。

Biodegradable particle manufacturers believe that the overall encapsulation is equivalent to injection molding a TPEE plastic part, in which the hardware products are encapsulated without chemical bonding, so the encapsulation is still feasible. Generally, TPEE with high hardness and hardness above 80A can be plated, but the hardware after plating should be plated as a whole. If only a part of the coating is plated, it is difficult to do so.

部分封装

Partial encapsulation

局部灌封，硬度偏软，强度不足，不易粘合。通过五金件的开孔处理，可以加强TPEE与五金件的物理机械结合，从而提高灌封牢固度。这种包胶在许多情况下是硫化橡胶零件包胶硬件，但橡胶是硫化的。如果使用注塑成型，则很难部分封装TPEE和硬件。如果五金打孔，TPEE胶会注入五金产品中，可以提高包胶的牢固度。

Local potting, soft hardness, insufficient strength, not easy to bond. Through the opening treatment of hardware, the physical and mechanical combination of TPEE and hardware can be strengthened, so as to improve the firmness of potting. This kind of rubber coating is vulcanized rubber parts in many cases, but the rubber is vulcanized. If injection molding is used, it is difficult to partially package TPEE and hardware. If the hardware is perforated, TPEE glue will be injected into the hardware products, which can improve the firmness of the glue.
