TPEE具有橡膠的彈性和工程塑料的強度；軟段賦予它彈性，使它象橡膠；硬段賦予它加工性能，使它象塑料；與橡膠相比，它具有更好的加工性能和更長的使用壽命；與工程料相比，同樣具有強度高的特點，而柔韌性和動態(tài)力學(xué)性能更好。那么生物降解顆粒TPEE的包膠方式是怎樣的呢？

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?

真正的封裝

True packaging

TPEE與塑料、金屬等材料通過化學(xué)作用，如分子滲透、極性基團或類似氫鍵的反應(yīng)連接和鍵合等化學(xué)作用，在兩種材料的結(jié)合界面形成牢固的焊接或結(jié)合，沒有任何機械和物理作用。無需粘合劑，可通過注塑成型直接與金屬粘合。

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.

在這種加工方式中，一般將TPEE和金屬件封裝為一個整體，TPE的硬度盡可能高（70~80A及以上），這樣才能達(dá)到一定的封裝效果，因為TPE的封裝和金屬沒有真正意義上的附著力（化學(xué)和分子水平），金屬被TPE的強度完全包裹。此外，金屬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).

假封裝

False encapsulation

TPEE與硬質(zhì)材料（塑料、金屬或其他材料）的物理和機械結(jié)合純粹是通過孔和凹槽等卡扣的方式，而不是簡單地依靠兩種材料的化學(xué)結(jié)合。兩種材料的界面在分子水平上沒有直接滲透，也沒有極性基團或氫鍵等反應(yīng)性鍵（范德華力）。用粘合劑粘上。

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.、

有時對于一些特殊的產(chǎn)品，橡膠只是部分覆蓋了金屬件的相應(yīng)位置，不利于TPEE與金屬件的牢固結(jié)合。在要涂敷的金屬表面上涂一層粘合劑是一種常見的想法。但實際上，由于TPEE與橡膠的成型工藝不同，對橡膠件與金屬件的粘合牢固性有著重要的影響。粘合劑類型的選擇對于此類金屬產(chǎn)品的涂層關(guān)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.

整體封裝

Integral package

生物降解顆粒廠家認(rèn)為，整體包封相當(dāng)于注塑一個TPEE塑料件，其中硬件產(chǎn)品是在沒有化學(xué)鍵合的情況下進(jìn)行包封的，所以包封還是可行的。一般硬度較高、硬度在80A以上的TPEE都可以鍍，但是鍍后的五金件要整體鍍，如果只鍍一部分鍍層是很難做到的。

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.

部分封裝

Partial encapsulation

局部灌封，硬度偏軟，強度不足，不易粘合。通過五金件的開孔處理，可以加強TPEE與五金件的物理機械結(jié)合，從而提高灌封牢固度。這種包膠在許多情況下是硫化橡膠零件包膠硬件，但橡膠是硫化的。如果使用注塑成型，則很難部分封裝TPEE和硬件。如果五金打孔，TPEE膠會注入五金產(chǎn)品中，可以提高包膠的牢固度。

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.
