一、产品用途详细介绍：中埋式止水带主要用于在混凝土变形缝、伸缩缝等混凝土内部设置的止水带产品，具有以橡胶材料弹性和结构形式来适应混凝土伸缩变形的能力。主要利用橡胶的高弹性和压缩变形性，在各种荷载下产生弹性变形，从而起到紧固密封有效地防止建筑构件的漏水，渗水，并起到减震缓冲作用，可确保工程建筑物的使用寿命。
First, the use of the product is introduced in detail: the middle-buried water-stop belt is mainly used in concrete deformation joints, expansion joints and other concrete products set up inside the water-stop belt, with the elasticity of rubber materials and structural form to adapt to the expansion deformation of concrete. The main use of rubber elasticity and compressive deformation under various loads to produce elastic deformation, so as to play a tightening seal effectively prevent the leakage of building components, water seepage, and play a role of shock absorption buffer, can ensure the service life of Engineering buildings.
二、特别说明：中埋式止水带中间的圆孔在安装止水带时一般都在建筑体的沉降缝处，而沉降缝的接口处是建筑体在发生沉降时产生“形变”距离的地方；由此看来，如果止水带是“平的单层面”的，那同样材料的橡胶的“抗形变沿伸性”就没有横断面为圆形的好（因为圆的还带有弧度可沿伸的由“半圆变为直径”的一段长度差别）；还有，圆形的横断面在沉降缝的断面上为双层，比“平板”的多了一层，可以起到防止“一层损坏”后仍能保持止水的作用。
2. Specifically, the circular hole in the middle of the middle-buried water stop belt is usually located at the settlement joint of the building when the water stop belt is installed, and the interface of the settlement joint is the place where the "deformation" distance of the building occurs when the settlement occurs. From this point of view, if the water stop belt is a "flat single-layer", then the rubber of the same material has no "deformation along extension" to be circular in cross-section. (Because the circle also has a length difference from "half circle to diameter" which can be extended along the radian; moreover, the circular cross section has two layers on the section of settlement joint, one layer more than the "flat plate", which can prevent the damage of the "first layer" and still keep the water stop.
三、用途及适应温度：
Use and adaptation temperature:
普通型：－25℃－+60℃；
Ordinary type: - 25 -+60;
耐寒型：－40℃－+60℃
Cold-resistant type: -40 -+60 (?)
四、本产品接头方法有两种：一种是采用粘接剂进行冷接头，一种是使用热硫化模具进行热接。
Fourth, there are two kinds of joint methods of this product: one is to use adhesive for cold joint, the other is to use hot vulcanization die for hot joint.
1、冷接法：采用橡胶止水带专用冷接胶水、采用搭接法把止水带需要接头的断面用磨光机磨平5~10厘米、涂胶水压实即可，具有强度高、凝固快的优点、施工方便、省时省力，可达到一般工程质量要求。
1. Cold bonding method: using special cold bonding glue for rubber water stop belt, using lap bonding method to smooth 5-10 cm cross section of water stop belt with a polishing machine, and then compacting with glue water. It has the advantages of high strength, fast solidification, convenient construction, time-saving and labor-saving, and can meet the general engineering quality requirements.
2、热接硫化法：使用与止水带匹配的热硫化模具及生胶片现场硫化热接，施工难度大，但接头效果理想，适合对工程质量要求严格的项目。
2. Hot joint vulcanization method: It is difficult to construct hot joint with hot vulcanization mould and biofilm matched with water stop belt, but the effect of joint is ideal, which is suitable for projects with strict engineering quality requirements.
