The surface of heat-resistant conveyor belt is covered with micro concave rubber mark. Scar is the most common appearance defect of heat-resistant conveyor belt. The main reasons are as follows:

　　橡膠可塑性過(guò)小，流動(dòng)性差，如果3-20包膠配合不合理，特別是小橡膠柔軟劑使用不正確，可塑性差，流動(dòng)性差，容易造成疤痕，解決方法:柔軟劑和增塑劑用量的合理使用,混合的可塑性和嚴(yán)格控制混合的均勻度,然后使橡膠符合需求的過(guò)程,折疊后平板硫化機(jī)、橡膠硫化速度太快橡膠是否仍沒(méi)有完全走,橡膠硫化已經(jīng)沒(méi)有了地方明亮的疤痕,解決方案:適當(dāng)控制橡膠硫化率為3,其耐熱膠粘劑固化速度是非常緩慢的,和氯丁橡膠的交聯(lián)劑是氧化鋅和氧化鎂,如果組變質(zhì)鎂氧化物吸收水分,活動(dòng)不防焦性能差,經(jīng)常出現(xiàn)硫速度太快,所以氧化鎂的質(zhì)量的控制是解決這個(gè)問(wèn)題的關(guān)鍵。塑料材料太大或太粘，由氣體引起硫化。

　　The plasticity of rubber is too small and the fluidity is poor. If the 3-20 compound is not reasonable, especially the use of small rubber softener is not correct, the plasticity is poor and the fluidity is poor, it is easy to cause scars. Solutions: the reasonable use of softener and plasticizer, the plasticity of mixing and strict control of the uniformity of mixing, and then make the rubber meet the demand process, After folding, if the vulcanization speed of flat vulcanizer and rubber is too fast, whether the rubber is still not completely gone, and there is no bright scar in rubber vulcanization. Solution: properly control the vulcanization rate of rubber to 3, and the curing speed of heat-resistant adhesive is very slow, and the crosslinking agent of Chloroprene rubber is zinc oxide and magnesium oxide. If the modified magnesium oxide absorbs water, the activity is not coke proof, Sulfur is often too fast, so the quality control of magnesium oxide is the key to solve this problem. The plastic material is too big or too sticky, which is vulcanized by gas.

　　如果粘接劑材料粘度過(guò)大，當(dāng)印版硫化機(jī)涂膜時(shí)，不容易擠出空氣，往往會(huì)造成氣痕。所以覆膜塑料的可塑性不能太大，一般大于0.4的手術(shù)是不理想的，尤其是氯丁橡膠，由于3-20和丁基苯的粘結(jié)性差，如果覆膜塑料的可塑性較大，很少出現(xiàn)亮疤。對(duì)產(chǎn)品的要求越來(lái)越高，對(duì)質(zhì)量的要求也越來(lái)越高，不僅產(chǎn)品的性能、耐久性和外觀(guān)都很美觀(guān)。傳送帶的外觀(guān)質(zhì)量沒(méi)有明確明確規(guī)定,但參考GB / t7894 - 2001的規(guī)定共同的傳送帶,HC的耐熱輸送帶,2297 - 92年化工行業(yè)標(biāo)準(zhǔn),外觀(guān)質(zhì)量執(zhí)行GB - 526織物芯輸送帶外觀(guān)質(zhì)量標(biāo)準(zhǔn),耐熱輸送帶的外觀(guān)質(zhì)量是一個(gè)重要指標(biāo),外觀(guān)質(zhì)量不僅是外觀(guān)問(wèn)題,對(duì)產(chǎn)品的研究也是很講究的。

　　If the viscosity of the adhesive material is too large, when the plate vulcanizer is coated, it is not easy to extrude air, which often causes air marks. Therefore, the plasticity of the coated plastic can not be too large, and the operation larger than 0.4 is not ideal, especially the chloroprene rubber. Due to the poor adhesion of 3-20 and butyl benzene, if the plasticity of the coated plastic is large, there are few bright scars. The requirements for products are higher and higher, and the requirements for quality are higher and higher, not only the performance, durability and appearance of products are very beautiful. The appearance quality of conveyor belt is not clearly defined by the state, but refer to the provisions of GB / t7894-2001 common conveyor belt, HC heat-resistant conveyor belt, the chemical industry standard of 2297-92. The appearance quality is in accordance with the appearance quality standard of gb-526 fabric core conveyor belt. The appearance quality of heat-resistant conveyor belt is an important index. The appearance quality is not only the appearance problem, but also the product research.
