PN（BW）止水条是由高分子、无机吸水膨胀材料与橡胶及助剂合成的具有自粘性能的一种新型建筑防水材料。遇水能吸水体积膨胀，挤密新老混凝土之间的缝隙，形成不透水的的可塑性胶体。该产品与一九八八年六月在北京通过部级鉴定，荣获一九九一年国家科技成果奖，并颁发证书成为国家认可的合格产品。该产品为解决混凝土施工缝的渗漏问题了新路，填补了我水材料的一项空白。产品质量达到 了世界水平。
PN (BW) stop bar is a new type of building waterproof material, which is made of macromolecule, inorganic water swelling material, rubber and auxiliaries. When the water can absorb water, the volume expands and the gap between the old and new concrete is squeezed to form an impermeable plastic colloid. In 1988 June, the product passed the ministerial appraisal in Beijing, and won the national science and technology achievement award in 1991, and issued a certificate to become a qualified product approved by the state. This product has opened a new way to solve the seepage problem of concrete construction joint, and has filled a blank of waterproof material in our country. Product quality has reached the world's leading level.

三、主要用途：
Three, the main use:
PN（BW）止水条是各种地下建筑构筑工程、水利工程、交通隧道工程、电厂冷却塔、市政给排水等砼砌混凝土工程施工缝防止漏的一种新、理想的材料，价格仅是橡胶止水带的四分之一、钢板止水带的五分之一，解决了橡胶和钢板止水带靠磨擦易产生绕渗的难题。
PN (BW) is a variety of underground building waterproof engineering, water conservancy, traffic tunnel engineering, power plant cooling tower, municipal water supply and drainage and other concrete masonry concrete construction joint is a new and ideal materials to prevent leakage, the price is only the rubber sealing belt 1/4, steel plate water stop 1/5, completely to solve the rubber and steel strip by friction prone problem of seepage around the.
四、使用方法：
Four, the use of methods:
1、采用PN（BW）止水条用于混凝土施工缝的防水、施工缝处可留作平缝、平面可以是粗糙的，也可以是比较光滑的，可心是水平施工缝也可以是竖向施工缝，只需扫净表面浮土，利用材料自身的粘性，将PN（BW）止水条粘贴在已浇混凝土的表面上，即可继续浇注下水段混凝土。
1, using PN (BW) sealing strip used for waterproof, concrete construction joint can be reserved for sewing, plane can be rough, can also be relatively smooth, Kexin is horizontal construction joints can also be vertical construction joints, just sweep the surface regolith, using viscous material itself, will PN (BW) seal has been pasted on the surface of concrete, can continue to the next section of water pouring concrete.
2、施工缝也可做成凹形接缝，然后放PN（BW）止水条，使其一部分露出施工缝表面，然后可浇注下段的混凝土。
2, the construction joints can also be made into concave joints, and then put PN (BW) sealing strip, so that part of it exposed to the surface of the construction joints, and then pouring the next section of concrete.
五、产品规格和包装：PN（BW）止水条用纸箱包装，现生产30mm*20mm,20mm*15mm两种规格，大规格每箱30米，分6盘、每盘5米。小规格每箱54米，分9盘，每盘6米。止水条隔离全部用防粘隔离纸包裹。并根据用户需要，可生产异型规格的膨胀止水条。
Five, product specifications and packaging: PN (BW) water seal carton packaging, production is now 30mm*20mm, 20mm*15mm two specifications, large size of 30 meters per box, 6 sets, 5 meters per disk. Small size, 54 meters per box, 9 sets, 6 meters per disk. All the sealing strips are wrapped with anti sticking paper. And according to user needs, can produce special-shaped specifications of expansion bar.
