橡膠止水帶
rubber waterstop
止水帶是利用橡膠高彈性和壓縮變形性的特點，在各種載荷下產生彈性變形，從而起到有效緊固密封，防止建筑漏水、滲水及減震緩沖作用。在一般較大工程的建筑設計中，由于不能連續澆注。可由于地基的變形，或由于溫度變化引起的混凝土構件熱脹冷縮等原因，需留有施工縫、沉降縫、變形縫，在這些縫處必須安裝止水帶來防止水的滲漏問題。
The water stop belt is elastic deformation under various loads by using the characteristics of high elasticity and compression deformation of rubber, so that it can effectively fasten and seal and prevent building leakage, seepage and shock absorption. In the architectural design of general large engineering, continuous casting can not be made. Due to the deformation of foundation or the expansion and contraction of concrete members caused by temperature changes, there are still need for construction joints, settlement joints and deformation joints. At these seams, water stops must be installed to prevent water leakage.
橡膠止水帶是采用天然橡膠與各種合成橡膠為主要原料，摻加各種助劑及填充料，經塑煉，混煉， 壓制成型，其品種規格較多，有橋型、山型、P型、R型、U型、Z型、乙型、T型、H型、E型、Q型等。該止水材料具有良好的彈性，耐磨性、耐老化性和抗撕裂性能，適應變形能力強、防水性能好，溫度使用范圍-45℃-+60℃。當溫度超過+70℃，以及強烈的氧化作用或受油類等有機溶劑侵蝕時，均不得使用該產品。
The rubber sealing strip is made of natural rubber and various synthetic rubber as the main raw material, and the filling material mixed with various additives, through mixing, mixing, molding, the more varieties of different specifications, bridge, mountain type, P type, R type, U type, Z type, T type, H type, type, E type and Q type etc.. The sealing material has good elasticity, wear resistance, aging resistance and tear resistance. It has strong deformation capacity and waterproof performance, and its temperature range is -45 -+60 C. The product should not be used when the temperature is more than +70 C, as well as the strong oxidation or the corrosion of organic solvents, such as oil.
止水帶主要用于混凝土現澆時設在施工縫及彎形縫內與混凝土結構成為一體的基礎工程，適用于受振動、易變形、荷載較大的建筑物及構筑物的接縫止水處理如：地鐵、道路、隧道、橋梁、伸縮縫、沉降縫、攔水壩、地下設施、隧道漏洞、輸水渡槽、高低跨建筑物、貯液構筑物等。
The waterstop is mainly used for foundation engineering of cast-in-place concrete in construction joints and when bending joints and concrete structure as a whole, suitable for vibration, easy deformation, large load of buildings and structures in the joint seal processing such as: subway, roads, tunnels, bridges, expansion joints and settlement joints, dams, underground facilities tunnel, leak, aqueduct and low cross building, liquid storage structures etc..

According to the material, it can be divided into natural rubber water stop belt, chloroprene rubber water stop belt, three ethylene propylene rubber water stop belt.
中埋式止水帶：
Middle buried water stop belt:
中埋式止水帶是利用橡膠的高彈性和壓縮變形性的特點，在各種載荷下產生彈性變形，從而起到有效緊固密封，防止建筑結構的漏水、滲水及減震緩沖作用。在許多工程建筑設計中，土建、水土結構之間都有一定的伸縮要求，并存在防水防震等問題，因此采用和安裝橡膠止水帶是有效地解決以上種種問題的手段。本產品主要用于混凝土現澆時設在施工縫及變形縫內，與混凝土結構成為一體的基礎工程、地下設施、隧道涵洞、輸水渡槽、擋水壩等，確保工程建設的使用壽命。
The middle buried waterstop is elastic deformation based on high elasticity and compression deformation of rubber under various loads, so that it can effectively fasten and seal and prevent leakage, seepage and shock absorption of building structure. In many engineering building designs, there are certain requirements for expansion and contraction between civil structures and water and soil structures, and there are problems such as water and shock proof. Therefore, the installation and installation of rubber water stop is an effective way to solve these problems. This product is mainly used for concrete cast-in-place engineering, underground facilities, tunnel culverts, water conveyance aqueducts and water retaining dams, which are built in the construction joints and deformation joints, and ensure the engineering construction life.
中埋式止水帶采用國家標準GB18173.2-2000《高分子防水材料止水帶》組織生產的。 因此我們可以按用戶要求生產各種形狀、尺寸的橡膠止水帶，另外還為不同工程、不同部位的需要備有十字型，丁字型、斜度型和內外轉角型產品，可適用于任何設計要求。
The middle - buried water stop belt is produced by the national standard GB18173.2-2000 "high polymer waterproof material water stop belt". Therefore, we can produce various shapes and sizes of rubber water stop according to user requirements. Besides, there are cross type, T-shaped, oblique and inside and outside corner products for different engineering and different parts, which can be applied to any design requirement.
中埋式止水帶廣泛應用于各種類型的混凝土結構中。例如：擋水壩、蓄水池、地鐵、涵洞、隧道等地下工程中，由于不能連續澆注，或由于地基的變形，或由于溫度變化引起混凝土構件的熱脹冷縮等原因，在澆注時常留有變形縫、施工縫，這些縫的防滲漏問題就要采用在變形縫的部位澆注橡膠止水帶的辦法來解決，它既能防止地下水（或外界水）滲漏到建筑結構中，又可防止建筑內的水漏到外界。
The buried zone is widely used in various types of concrete structures. For example: dam, reservoir, subway, culverts, tunnels and other underground projects, due to the continuous casting, or as a result of the ground deformation due to temperature changes, or the cause of concrete expansion and contraction, often left in the casting deformation joints, construction joints, these joints leakage problems must be used in the deformation zone the way of joint parts casting rubber seal to solve, it can prevent the leakage of groundwater (or outside water) to the building structure, and can prevent water leakage to outside buildings.
橡膠止水帶在運輸時，應要避免陽光直射，勿與熱源、油類及有害溶劑接觸。成品應取直平放，勿加重壓。存放場所最好保持-10-+30，相對濕度40%-80%。
The rubber sealing belt during transportation, should avoid direct sunlight, do not contact with heat, oil and harmful solvent. The finished product should be put straight, without heavy pressure. The best storage place is -10-+30, and the relative humidity is 40%-80%.
