产品名称: SD 101
 
化学名称: 聚环氧琥珀酸盐阻垢剂
 
结  构  式:
   
 
产品性能:
  聚环氧琥珀酸盐(PESA)是一种新型的环保型阻垢缓蚀剂,不含磷、氮,并可实现生物降解,对CaCO3,BaSO4,SrSO4,CaF2,CaSO4有很好的阻垢性能,其阻垢效果优于目前常用含磷阻垢剂,特别适用于高碱度、高硬度、高PH值水系的锅炉水处理、冷却水处理、油田注水、海水淡化、膜分离等,是现有阻垢剂的更新换代产品。
 
物化性质:
 
 外观 (25℃)  无色透明至淡黄色液体
 含量  ≥35.0% (含聚环氧琥珀酸盐)
 PH值 (原液)  >7.0
 比重 (25℃,g/ml)  ≥1.30
 粘度 (30℃),dl/g  0.009-0.039
 
特         性:
 
不含磷、氮,符合当今限磷排放的环保要求;
阻垢效果优于目前常用的含磷阻垢剂;
即可阻垢又可缓蚀,可形成无磷或低磷阻垢缓蚀剂配方;
与PBTCA复配后有增效作用,用量更少,效果更好。
 

使用方法:

  阻垢剂投加量与阻垢效果对比:
 
 阻垢剂投加量mg/L  5.0  7.5  10.0  12.0
 阻垢效果  71%  82.5%  87.2%  85%
  当PESA与PBTCA(2-膦基-1,2,4-丁三酸(PBTCA))复配,效果更好;
(对比试验,仅供参考,不做使用推荐量)。
 

安全、包装和储存:

 

1.使用浓度无刺激性,无腐蚀性。
2.不慎溅到皮肤或眼睛请立即用大量清水冲洗。
3.25kg或250kg塑桶或衬塑铁桶包装或按用户要求。
4.室温避光储存

 
 
Name: Polyepoxysuecinic Acid
 
Structure:
   
 
Application:
  be used as scale & corrosion inhibitor for cooling water treatment for steel & iron, petroleum, chemistry and metallurgy, as well as hotel, office, central air conditioning system, it can be either used monomer or formulation, it can greatly reduce emission of phosphorous when it’s combined with phosphorous series scale inhibitor, so it has remarkable environmental effects.
 
Specifications:
 
Appearance Colorless or amber clear liquid
Solidity ≥35.0%
Density(20℃),g/cm3≥ 1.30
PH >7.0
Viscosity(30℃),dl/g 0.009-0.039
 
Property:
 
This is a soluble polyer and an effective chelating agents with performance of chelating multi valence metallic ion.Its appearance is colorless or amber lucent liquid.Because there isn't nitrogen and phosphorous its molecular structure,it's degradable environmental product,which belongs to green water treatment chemicals,PESA is mainly used for cooling water treatment,it's not only applicable to low alkalinity and hardness water,but also high alkalinity,temperature,PH and hardness water.
It's well compatible with chlorine,it isn't affected by nitrogen concentration in scale inhibition,it's better than usual HEPD, ATMP under same conditions,There's quite well synergistic effect and corrosion inhibition where it's formulated with other phosphate and PBTCA,etc.
 

Package and storage:

 

To use net weight 25kg or 250kg/plastic drum, stored in cool and ventilated place.
