盾構(gòu)行業(yè)中使用長益聚氨酯刮泥板的必要性

東莞市長益新材料有限公司網(wǎng)站：www.cynew.com

（價格請跟客服人員咨詢）地鐵盾構(gòu)是城市地鐵施工中一種重要的施工技術(shù)，是在地面下暗挖隧洞的一種施工方法。它使用地鐵盾構(gòu)機在地下掘進，在防止軟基開挖面崩塌或保持開挖面穩(wěn)定的同時，在機內(nèi)安全地進行隧洞的開挖和襯砌作業(yè)。

盾構(gòu)渣土皮帶機主要由輸送帶、洞內(nèi)水平皮帶機、垂直夾帶機、轉(zhuǎn)載機、滾筒拉緊等裝置組成。利用皮帶機的機尾搭在盾構(gòu)機臺車上，渣土通過盾構(gòu)機的皮帶轉(zhuǎn)運到連續(xù)皮帶輸送機上，輸送到始發(fā)井，然后通過垂直夾帶機輸送機直接傳輸?shù)降孛嬖脸亍?

客戶公司輸送帶因滾筒表面黏結(jié)物太多造成皮帶突然斷裂,盾構(gòu)渣土皮帶機作業(yè)過程中，皮帶清掃器的使用非常重要，這主要是由地下渣土的特性所決定，地下渣土有泥土和砂石等構(gòu)成， 含有水分，其濕度和黏度都很大，皮帶機運行過程中，皮帶表面會黏結(jié)，如清掃不徹底，就對設(shè)備運行安全產(chǎn)生影響，黏結(jié)的砂石泥土一旦卷入皮帶滾筒，包裹在滾筒表面形成厚度不均勻的硬塊，改變滾筒的直徑和外形，積累到一定的程度，必將引起皮帶機損傷，設(shè)置會造成皮帶撕裂等重大損傷事故。

長益公司把皮帶清掃器作為一項專門的技術(shù)來研究，為了保證清掃效果，研制出碳化鎢刀頭刮泥板。刮刀采用聚氨酯柔性材料，具有高耐磨，耐沖擊及良好的柔韌性等優(yōu)點；刮刀刀頭部分采用碳化鎢鋼材質(zhì)，它高硬度，耐高溫，耐腐蝕，不銹等優(yōu)點。在盾構(gòu)渣土皮帶機實際作業(yè)中， 會時常有諸如帶有溫度、有菱角的砂石，或濕的泥土等，一旦卡進清掃器，刮刀因為是聚氨酯材質(zhì)，它會有一定緩沖作業(yè)，避免直接劃傷皮帶或損壞清掃器，碳化鎢鋼部分又會輕松刮去這些物料，保持皮帶表面清潔，從而提高系統(tǒng)運行的安全性，降低設(shè)備故障，提高設(shè)備可利用率。

長益公司研發(fā)的碳化鎢鋼皮帶清掃器，幫助客戶解決了皮帶機運行過程中的實際問題，自客戶使用長益清掃器這一年多以來，設(shè)備的應(yīng)用非常穩(wěn)定。

產(chǎn)品真正好與不好需要終端用戶體驗以后說了算。在魚龍混雜的電商時代中，長益堅信只有良好的質(zhì)量和服務(wù)態(tài)度才能贏得好口碑，只有好的質(zhì)量才能創(chuàng)造出更大的經(jīng)濟價值。了解更多有關(guān)聚氨酯清掃器資訊可以登陸長益新材料網(wǎng)站http://www.cynew.com 或直接撥打400-833-9008/13925775994/15768614193，我們期待您的來電。

The need to use Changyi polyurethane scraper in the shield industry

Dongguan Changyi New Materials Co., Ltd. Website: www.cynew.com

(Please consult customer service staff for the price.) Metro shield is an important construction technique in urban subway construction. It is a construction method for digging tunnels under the ground. It uses the subway shield machine to dig underground, and prevents the excavation and lining of the tunnel safely in the machine while preventing the soft foundation excavation surface from collapsing or keeping the excavation surface stable.

The shield muck belt conveyor is mainly composed of a conveyor belt, a horizontal belt conveyor in the hole, a vertical entrainment machine, a transfer machine, and a drum tensioning device. The tail of the belt conveyor is placed on the shield machine trolley, and the muck is transported to the continuous belt conveyor through the belt of the shield machine, transported to the originating well, and then directly transferred to the ground slag pool by the vertical entrainer conveyor. .

The conveyor belt of the customer company is suddenly broken due to too much adhesive on the surface of the drum. During the operation of the shield muck belt conveyor, the use of the belt cleaner is very important, which is mainly determined by the characteristics of the underground muck. It consists of earth and sand, contains moisture, and has a large humidity and viscosity. During the operation of the belt conveyor, the surface of the belt will stick. If the cleaning is not thorough, it will affect the operation safety of the equipment. Once the bonded sand and gravel soil is involved The belt roller is wrapped around the surface of the drum to form a hard block with uneven thickness. Changing the diameter and shape of the drum and accumulating it to a certain extent will inevitably cause damage to the belt conveyor, which may cause major damage such as tearing of the belt.

Changyi Company studied the belt cleaner as a special technology. In order to ensure the cleaning effect, a tungsten carbide cutter head scraper was developed. The scraper is made of polyurethane flexible material, which has the advantages of high wear resistance, impact resistance and good flexibility. The scraper head is made of tungsten carbide steel, which has the advantages of high hardness, high temperature resistance, corrosion resistance and stainless steel. In the actual operation of the shield muck belt conveyor, there are often sandstones with temperature, water chestnuts, or wet soil. Once stuck into the sweeper, the scraper will have a certain buffering operation because it is made of polyurethane. Avoid directly scratching the belt or damaging the cleaner. The tungsten carbide steel part can easily scrape off these materials and keep the belt surface clean, thus improving the safety of the system operation, reducing equipment failure and improving equipment availability.

The tungsten carbide steel belt cleaner developed by Changyi Company helps customers solve the practical problems in the operation of the belt conveyor. Since the customer used Changyi Cleaner for more than a year, the application of the equipment has been very stable.

The product really good and bad needs the end user experience to have the final say. In the mixed e-commerce era, Changyi firmly believes that only good quality and service attitude can win a good reputation, only good quality can create greater economic value.
