輸送帶粘接力缺乏導(dǎo)致接頭脫膠的原因大致可分為：資料與施工，即資料質(zhì)量與施工工藝。下面來詳細(xì)看下內(nèi)容吧。

The reasons for the lack of adhesive force of conveyor belt leading to joint degumming can be roughly divided into: data and construction, that is, data quality and construction technology. Now let's take a detailed look at the content.

1、冷硫化接頭資料

1. Cold vulcanization joint data

冷粘接頭適合于中低強(qiáng)度分層帶的快速接頭操作，可運(yùn)用冷硫化粘接劑SK313來達(dá)到足夠大的粘接強(qiáng)度，冷硫化粘接劑SK313對橡膠、金屬、織物、皮革的粘接力超過德國DIN工業(yè)標(biāo)準(zhǔn)，達(dá)到與熱硫化同級，固化后膠層柔韌，環(huán)境耐性強(qiáng)，耐老化，接頭的曲撓性好。

The cold bonded joint is suitable for the quick joint operation of the medium and low strength layered belt. The cold vulcanized adhesive sk313 can be used to achieve sufficient bonding strength. The adhesion of the cold vulcanized adhesive sk313 to rubber, metal, fabric and leather exceeds the German DIN industrial standard and reaches the same level as the hot vulcanization. After curing, the adhesive layer is flexible, with strong environmental resistance, aging resistance and good flexibility of the joint.

冷粘接頭對所運(yùn)用膠水的粘接性能要求很高，運(yùn)用一般的膠水，要么粘接力缺乏，要么便是為了進(jìn)步粘接力，樹脂含量高，膠層固化硬度大，抗曲撓性差。而且冷粘接頭的施工對于操作人員的技能也有嚴(yán)格要求，比方膠水涂刷的厚度，分次分層涂刷及粘接貼合時膠層干燥程度的判斷、織物層間膠層厚度的控制等等。

Cold bonded joints have high requirements for the bonding performance of the glue used. The use of general glue is either lack of bonding force, or it is to improve the bonding force. The resin content is high, the curing hardness of the adhesive layer is large, and the bending resistance and flexibility are poor. Moreover, the construction of cold bonded joints also has strict requirements for the professional skills of operators, such as the thickness of glue brushing, the judgment of the dryness of the adhesive layer when brushing and bonding in layers, the control of the thickness of the adhesive layer between fabric layers, and so on.

冷硫化接頭在Z后還需求在接頭縫隙處張貼修補(bǔ)條，對粘接面形成保護(hù)與加強(qiáng)，防止起層刮傷導(dǎo)致開膠脫膠。

After the cold vulcanization joint is Z, it is also required to post a repair strip at the joint gap to protect and strengthen the bonding surface, so as to prevent the layer scratch from causing the opening and degumming.

2、熱硫化接頭資料

2. Hot vulcanized joint data

熱硫化接頭需求熱硫化膠漿、熱硫化芯膠、面膠，熱硫化芯膠填充在輸送帶的織物層或鋼絲繩之間，起填充與粘接效果，具有良好的粘接性，硫化后的曲撓性、柔韌性好。熱硫化面膠具有抗拉耐磨的特色，可以在輸送帶表層形成保護(hù)層，進(jìn)步接頭強(qiáng)度，延伸接頭運(yùn)用壽命。假如兩種膠料質(zhì)量差、雜質(zhì)含量多，在硫化后粘接力很簡單缺乏，無法粘接。

Hot vulcanized joints require hot vulcanized mastic, hot vulcanized core rubber and surface rubber. The hot vulcanized core rubber is filled between the fabric layer or steel wire rope of the conveyor belt, which has the effect of filling and bonding, has good adhesion, and has good flexibility and flexibility after vulcanization. The hot vulcanized surface rubber has the characteristics of tensile and wear resistance, which can form a protective layer on the surface of the conveyor belt, improve the strength of the joint and extend the service life of the joint. If the quality of the two compounds is poor and the content of impurities is high, the bonding force after vulcanization is very simple and lacking, so it is impossible to bond.

熱硫化膠漿相同起粘接效果，看似與芯膠效果重疊，可是膠漿自身良好的浸潤性、流動性使膠漿可以與織物層、鋼絲繩完全結(jié)合，內(nèi)部存在的氣泡縫隙，確保接頭的密實(shí)性，一起供給強(qiáng)壯的粘接力，是熱硫化接頭必不可少的一種資料。

The hot vulcanized adhesive has the same bonding effect, which seems to overlap with the core adhesive effect, but the good wettability and fluidity of the adhesive make the adhesive completely combined with the fabric layer and steel wire rope, eliminate the internal bubble gap, ensure the compactness of the joint, and provide strong bonding force together, which is an indispensable material for the hot vulcanized joint.

山東輸送帶廠家認(rèn)為有些熱硫化接頭脫膠便是由于熱硫化膠漿沒有運(yùn)用或運(yùn)用過少，接頭結(jié)合度不夠，面對強(qiáng)壯的皮帶拉力一扯就斷。熱硫化接頭的硫化過程也需求良好的技術(shù)與經(jīng)歷，升溫過程中同步提升壓力，達(dá)到硫化溫度后保溫保壓硫化，硫化的時刻要控制好，不能硫化不完全，也不能過硫。

Shandong conveyor belt manufacturers believe that some hot vulcanized joints are degummed because the hot vulcanized mortar is not used or used too little, and the connection degree of the joint is not enough. In the face of strong belt tension, it will break when pulled. The vulcanization process of hot vulcanization joints also requires good technology and experience. During the temperature rise process, the pressure is increased synchronously. When the vulcanization temperature is reached, the vulcanization is carried out with heat preservation and pressure holding. The vulcanization time should be well controlled, and neither incomplete vulcanization nor over vulcanization is allowed.

輸送帶在運(yùn)用中，接頭簡單脫膠，一旦輸送帶接頭接頭脫膠，會導(dǎo)致輸送帶無法運(yùn)用，嚴(yán)重的情況下還會形成整個輸送線癱瘓及損壞，所以以上所講解內(nèi)容要認(rèn)真看，您有疑問可關(guān)注網(wǎng)站http://ujkdbkh.cn聯(lián)系我們。

During the operation of the conveyor belt, the joint is simply degummed. Once the joint of the conveyor belt is degummed, the conveyor belt will not be used, and in serious cases, the whole conveyor line will be paralyzed and damaged.
