輸送帶是帶式輸送機(jī)的主要部件，主要用于煤炭、礦山、冶金、化工、建筑和交通等部門的大規(guī)模連續(xù)化運(yùn)輸，運(yùn)輸?shù)奈锪戏譃閴K狀、粉狀、糊狀和成件物品等。由于受工礦條件、運(yùn)行時(shí)間、意外情況等因素的影響輸送帶出現(xiàn)磨損、老化、脫膠、劃傷、撕裂等問題時(shí)有發(fā)生。輸送帶劃傷后如何快速有效的進(jìn)行修復(fù)，是很多企業(yè)設(shè)備管理者非常關(guān)注的問題。
Conveyor belt is the main component of belt conveyor, which is mainly used for large-scale continuous transportation in coal, mining, metallurgy, chemical industry, construction and transportation departments. The materials transported are divided into block, powder, paste and finished goods. Due to the influence of industrial and mining conditions, operation time, accidents and other factors, conveyor belt wear, aging, degumming, scratch, tear and other problems occur from time to time. How to repair the scratch of conveyor belt quickly and effectively is a problem that many enterprise equipment managers pay close attention to.
針對(duì)輸送帶劃傷修復(fù)問題，企業(yè)一般會(huì)采用機(jī)械連接方式和熱硫化膠合連接方式，但是均存在諸多弊端，比如：采用機(jī)械連接方式進(jìn)行修復(fù)后其膠帶連接部的強(qiáng)度削弱，容易疲勞損壞，使用壽命短而且接頭不平服，運(yùn)行中存在沖擊性對(duì)托輥的損傷嚴(yán)重，并伴有漏料問題；采用熱硫化膠合連接方式進(jìn)行修復(fù)時(shí)工藝復(fù)雜時(shí)間長(zhǎng)，受環(huán)境溫度和濕度影響較大，而且接頭硫化部位易起皮開裂。
For the problem of conveyor belt scratch repair, enterprises generally use mechanical connection and hot vulcanization bonding connection, but there are many disadvantages, such as: after the mechanical connection is used for repair, the strength of the belt joint is weakened, easy to fatigue damage, short service life, uneven joint, impact in operation, and serious damage to the idler, There is also a problem of material leakage; When using the hot vulcanization bonding connection method for repair, the process is complex, the time is long, and it is greatly affected by the environmental temperature and humidity, and the vulcanized part of the joint is easy to peel and crack.
除此之外還可以采用碳納米聚合物材料解決輸送帶劃傷問題，與我們常用的修復(fù)方法相比。
In addition, carbon nano polymer material can be used to solve the scratch problem of conveyor belt, compared with our common repair methods.
該方法的優(yōu)勢(shì)還是很明顯的：該材料是一種由天然橡膠與聚氨酯的改性材料，優(yōu)點(diǎn)是固化速度快，與基材的粘結(jié)強(qiáng)度高、耐老化、抗磨損、耐腐蝕，并具有350%的延展率。
The advantages of this method are obvious: firstly, the material is a kind of modified material made of natural rubber and polyurethane. Its biggest advantages are fast curing speed, high bonding strength with the substrate, aging resistance, wear resistance, corrosion resistance, and 350% ductility.
可用于修復(fù)各種橡膠傳送帶、襯膠罐蝶閥密封、電纜、水輪機(jī)、礦山溜槽、污水處理設(shè)備等；并且修復(fù)過程也很簡(jiǎn)單，對(duì)劃傷部位進(jìn)行表面處理，然后涂抹材料等材料固化即可。無需專門的工具，簡(jiǎn)簡(jiǎn)單單幾步就可以完成修復(fù)，為企業(yè)節(jié)省了大量人力、物力、財(cái)力。
It can be used to repair all kinds of rubber conveyor belt, rubber lined tank butterfly valve seal, cable, water turbine, mine chute, sewage treatment equipment, etc; And the repair process is also very simple, the scratch part surface treatment, and then apply materials and other materials can be cured. Without special tools, the repair can be completed in a few steps, saving a lot of manpower, material and financial resources for the enterprise.
