  • 一站式.jpg

    品    名:出口有機(jī)磷阻垢緩蝕劑(低磷)

    型    號:SGR0825

    主要成份:有機(jī)膦酸鹽、膦羧酸、膦酸酯、羧酸鹽共聚物、磺酸鹽共聚物、唑類及助劑等。

    理化指標(biāo):

    項(xiàng)       目

    指       標(biāo)

    外       觀

    淡黃或棕黃色液體

    密度(20℃)g/cm3

    ≥1.15

    pH值

    7-9

    有機(jī)膦酸鹽(以PO43-計) , %

    2.0~6.8

    性能特點(diǎn):

    (1)為綠色水處理配方,同時具有生物可降解、低磷的特點(diǎn),排放水不需經(jīng)特殊處理即可達(dá)到國家環(huán)保污水排放二級標(biāo)準(zhǔn)(總磷≤1.0mg/L)。

    (2)與其它全有機(jī)堿性處理配方相比,更適用于高硬度、高濃縮倍數(shù)以及高溫、長停留時間的工況條件。該藥劑使用了最新的高效分散劑和緩蝕劑,可有效控制金屬(碳鋼、銅合金、不銹鋼等)腐蝕和換熱器結(jié)垢。

    用    途:作為阻垢緩蝕劑,在高Ca2+、高堿的水質(zhì)下有優(yōu)異的阻碳酸鹽垢能力,分散性能較為良好,適用于高濃縮倍數(shù)、高pH值的循環(huán)冷卻水系統(tǒng)。

    使用方法:投加量視應(yīng)用系統(tǒng)的水質(zhì)指標(biāo)和工藝參數(shù)而異,一般按補(bǔ)充水量計,投加濃度控制在20~80mg/L左右,適用pH值7.0-9.5。

    包裝貯運(yùn):用25kg、200 kg、1000kg塑料桶包裝,存放于陰涼干燥處,貯存期十二個月,搬運(yùn)時小心輕放,防止撞擊。



    Export circulation water scale inhibitor (low phosphine)

    Name: Export organic phosphonate scale inhibitor (low phosphonate)

    Model number: SGR 0825

    Main components: organic phosphonate, phosphonate carboxylic acid, phosphonate, carboxylate copolymer, sulfonate copolymer, azole and additives, etc.

    physicochemical indexes:

    08252.jpg

     Performance features:

    (1) It is a green water treatment formula, and it has the characteristics of biodegradable and low phosphorus. The discharged water can meet the national environmental protection sewage discharge secondary standard (total phosphorus 1.0 mg/L) without special treatment.

    (2) Compared with other all-organic alkaline treatment formulations, it is more suitable for high hardness, high concentration multiple, high temperature and long residence time. The agent uses the latest high efficiency dispersion and corrosion inhibitor, which can effectively control metal (carbon steel, copper alloy, stainless steel, etc.) corrosion and scaling of heat exchanger.

    Use: as a scale inhibitor and corrosion inhibitor, in the high Ca2+, High alkali water quality has excellent carbonate scale resistance ability, the dispersion performance is relatively good, suitable for the circulating cooling water system with high concentration ratio and high pH value.

    Use method: the adding amount depends on the water quality index and process parameters of the application system. Generally, the adding concentration is controlled at about 20 ~ 80 mg/L, and the pH value is 7.0-9.5.

    Packaging and storage: with 25kg, 200 kg, 1000kg plastic barrels, stored in a cool and dry place, storage period of 12 months, carefully placed when handling to prevent impact.
