1 产品性能（ Product performance）

高效泥岩分散剂是一种强效型粘泥分散剂，具有很强的分散性和渗透性。对盾构泥岩渗透性强，能够迅速分解剥离泥岩。也能够有效解决石油钻探和地质钻探中遇到的黏泥、油泥裹钻问题，具体方式原理为通过分解剥离作用，直接、快速地渗透到粘土胶层结构中，将粘土氧化分解，逐渐脱落剥离，随水流出。

High efficiency mudstone dispersant is a kind of highly effective clay dispersant with strong dispersibility and permeability. It has strong permeability to shield mudstone and can quickly decompose and peel mudstone. Also can effectively solve the oil drilling and geological drilling encountered slime, mud wrapped drilling problem, the specific way principle is through decomposition stripping action, directly, quickly permeate into the clay layer structure, the clay oxidation decomposition, gradually off stripping, with water flow out.

2 产品用途（Product uses:）

高效泥岩分散剂适用于盾构隧道、钻探勘探、电站和炼油厂等部门，解决由于隧道系统和循环管道系统中泥浆沉积，消除形成大量的泥浆凝胶沉积和堵塞。

Efficient mudstone dispersant is mainly suitable for shield tunneling, drilling and prospecting, power stations and oil refineries and other departments, due to the tunneling system and circulation pipeline system by mud mud deposition, the formation of a large number of mud gel deposition, blocking.

4 方法和效果（Method and performance）

首先将高粘性土分散剂按照分散剂：水=1:1的比例在搅拌条件下配制成分散剂溶液，搅拌时间大于5min即可使用。其次，将配置好分散剂溶液分次注入已经结泥饼的土仓中，首次注入量为3t，然后每隔半小时转动一次刀盘以利于分散剂和土体的充分混合。8h后每隔2h注入0.5t分散剂溶液，直至注完为止。24~48h后，开始慢慢推进，将土仓渣土慢慢排出即可。分散剂也可用于预防盾构刀盘和土压力仓的结饼，使用方法为将分散剂配制成20%的溶液，然后在推进过程中连续注入土仓即可。

First of all, the dispersant of high cohesive soil was prepared according to the ratio of dispersant: water =1:1 under the condition of agitation, and the agitation time was more than 5min before use.Pour the dispersant solution into the soil chamber with mud cake in batches. The first injection volume is 3T, and then turn the knife plate every half an hour to facilitate the full mixing of dispersant and soil. After 8h, 0.5t dispersant solution was injected every 2h until the injection was finished.24~48h later, start to slowly advance, the soil bin slowly discharge can be.Dispersants can also be used to prevent cake formation in shield cutters and earth pressure chambers by compounding dispersants into a 20% solution and continuously injecting them into the earth chamber during propulsive.
