四川有卖-钢边天然橡胶止水带350*8mm

EVA止水带是由聚氯乙烯树脂与各种填加剂，经混合、造粒、挤出等工序而制成的止水材料。该产品利用弹性体材料具有的弹性变形特性在建筑构造接缝中起防漏、防渗作用，且具有耐腐蚀、耐久性的特点。
The EVA water stop belt is a water stop material made of PVC resin and a variety of additive, by mixing, granulation, extrusion and other processes. The product takes advantage of the elastic deformation characteristics of elastomeric materials to prevent leakage and seepage in building structural joints, and has the characteristics of corrosion resistance and durability.
应用范围：
Application scope:
EVA止水带主要用于混凝土浇筑时设置在施工缝及变形缝内与混凝土构成为一体的基础工程。如隧道、涵洞、引水渡槽、拦水坝、烛液构筑物、底下设施等。
The EVA water stop belt is mainly used for the foundation engineering which is set up in the construction seam and the deformation joint and the concrete in the concrete pouring. Such as tunnel, culvert, aqueduct, dams, candle liquid structures, under the facilities etc..
施工方法：
Construction methods:
EVA止水带施工方法与橡胶止水带相同。在浇埋时要使其与混凝土界面贴合平整，接头部分粘结牢固，浇埋过程中要以适当的力充分震捣混凝土，使其与混凝土结合良好，以获得的止水效果。
The construction method of EVA water stop belt is the same as that of rubber water stop belt. During embedment, the interface between the concrete and the concrete should be smoothed, and the joints must be firmly bonded. During the process of burying, we must adequately vibrate the concrete with the proper force, so that the sealing effect can be well combined with the concrete.
施工注意事项：
Matters needing attention in Construction:
1、 在施工过程中，由于混凝土中有许多尖角的石子和钢筋，操作时要注意避免对止水带造成机械损伤。
1. In the course of construction, because there are many sharp corners of the stone and steel in the concrete, we should avoid the mechanical damage to the water stop belt during the operation.
2、 在定位塑料止水带时，要使其与混凝土界面贴合平整，不能出现止水带翻转、扭曲等现象，否则应及时进行调正。
2, when positioning inversion and distortion can not occur. Otherwise, it should be adjusted in time.
3、 在浇筑固定止水带时，应防止止水带发生偏移，影响止水效果。
3. When placing the fixed water stop belt, the migration of the water stop zone should be prevented and the effect of water stop should be affected.
4、 塑料止水带接头可利用粘接、热焊等方法，保证接头牢固。
4. The joint of plastic water stop belt can be used for bonding and hot welding to ensure the joint firm.
5、 浇筑混凝土过程中要注意充分振捣，以达到止水带和混凝土充分结合。
5, in the process of pouring concrete, we should pay attention to the full vibration, so as to achieve the full combination of water stop and concrete.
by mixing, granulation and extrusion processes, also known as "PVC water stop".
