橡膠止水帶的規(guī)格、型號表示方法如下？
The specifications and models of the rubber water stop belt are as follows.
通常我們將止水帶膠膠種：（NR)表示天然膠;（CR)表示氯丁膠;（NBR)表示丁腈膠。產(chǎn)品代號：FRD表示我公司生產(chǎn)的。
Usually we have adhesive tape of water stop: (NR) for natural gum; (CR) for chloroprene; (NBR) for nitrile gum. Product Code: FRD is the product of our company.
FRDGB型（NR）350 表示采用我公司生產(chǎn)的橡膠止水帶，寬度為350毫米，材料為天然橡膠。適用于淡水防滲工程，適用溫度-40～60℃。
FRDGB (NR) 350 means the rubber water stop belt produced by our company, the width is 350 millimeter, the material is natural rubber. It is suitable for fresh water seepage control project, which is suitable for temperature -40 ~ 60.
FRDGB型（CR）450 表示采用我公司生產(chǎn)的橡膠止水帶，寬度為450毫米，材料為氯丁橡膠。適用于含酸堿等污水防滲工程，適用溫度－35～60℃。
FRDGB (CR) 450 means the rubber water stop belt produced by our company, the width is 450 millimeter, the material is chloroprene rubber. Suitable for acid sewage seepage control project, suitable temperature to 60 DEG C - 35.
FRDGB型（NBR）450 表示采用我公司生產(chǎn)的橡膠止水帶，寬度為450毫米，材料為丁腈膠。適()用于含石油基油類的污水防滲工程，適用溫度-35～60℃。
FRDGB (NBR) 450 means the rubber water stop belt produced by our company, the width is 450 millimeter, the material is Ding Jing glue. Suitable for the sewage seepage engineering with oil based oil, suitable for the temperature -35 ~ 60.
橡膠止水帶規(guī)格 300*8外貼式止水帶
Rubber water stop belt specification 300*8 external sealing belt
注:橡膠止水帶是以天然橡膠與各種合成橡膠為主要原料加以幾種摻加各種助劑及填充料,經(jīng)塑煉、混煉、壓制成型.橡膠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(chǎn)生彈性變形，從而起到有效緊固密封，防止建筑構造的漏水、滲水及減震緩沖作在一般較大工程的建筑設計中，由于不能連續(xù)澆注，或由于地基的變形，或由于溫度的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橡膠止水帶來防止水的滲漏問題。 止水帶主要用于混凝土現(xiàn)澆時設在施工縫及變形縫內(nèi)與混凝土結構成為一體的基礎工程，如地下設施、隧道涵洞、輸水渡槽、攔水壩、貯液構筑物等。
Note: the rubber sealing strip is natural rubber and synthetic rubber as main raw material and adding some additives and fillers, the plastication, mixing, pressing and molding. The rubber sealing strip is the rubber high elasticity and compression deformation characteristics, produce elastic deformation under various loads, so as to effective sealing, prevent Water Leakage, seepage and buffer construction in architectural design generally larger projects, due to the continuous casting, or as a result of the ground deformation, or concrete expansion caused by the variation of temperature and cold, need to have construction joints and settlement joints, deformation cracks, these cracks in must be located in the rubber sealing to prevent water leakage problems caused. The waterstop is mainly used for cast-in-place concrete when in construction joints and deformation joints and concrete structure has become one of the basic engineering facilities, such as underground tunnels, culverts, dams, aqueducts, liquid storage structures etc..
