配制。

3.聚合物溶液浓度的选择,我公司建议为0.1%到0.3%,即1升水中加1到3克聚合物粉剂。浓度选择要考虑如下因素:

配制罐小而每天用药量大,建议配的稍浓一些(如0.3%);

聚合物分子量很高时,建议配的稍稀一些(如0.1%);

聚合物溶液投到污水中,如因设备原因分散状况不太好时,建议配的稍稀一些。

总之,聚合物浓度过大,会造成搅拌器马达负荷过大,也会造成进入污水后分散状况不好,影响使用效果,配得稀一些有助于提高使用效果。

4.配成的溶液不要用离心泵转移,以免高速旋转的叶片造成聚合物的剪切降解。

5.配制的具体方法如下:在容器(如实验室的烧杯,工厂的配制罐)中加入一定量的清水,按清水量及浓度计算所需的粉状聚合物量,称出聚合物;开启电动搅拌器,将清水搅出漩涡,搅拌器叶片末端的线速度不要超过8米/秒,以免造成聚合物降解;但又不能太慢,以免聚合物颗粒浮在水面上,或在水中下沉、结团。将聚合物缓缓撒入水的漩涡中,直到撒完。注意聚合物颗粒进入水里后不能互相粘连、结团。然后再搅拌一段时间,使聚合物颗粒充分溶解,后成为均匀、透明、粘稠的溶液,无肉眼可见的团块。这段搅拌时间按下面方法确定:

在夏季水温较高时,阴、阳离子型聚合物需搅拌1小时左右,非离子型聚合物需搅拌2小时左右;

700-1100

750-1200

45-70

300-500

More than 90

550-750

Less than or equal to 15

utrageous products two processed products the effective content of lower prices naturally low every customer's inquiry and we have to take the time to explain the price difference with other companies so why play and this is often to keep customers

Prices and specifications of anionic polyacrylamide have great relations in short is the manufacturing cost is high quality high molecular weight and high price of high molecular weight is divided into 600-1800 000 molecular weight degree of hydrolysis is 10-45% high hydrolysis products used for thickening and thickening which determines the final price of the product on paper machine

The current market price of anionic polyacrylamide between 6000-14000 users at the time of purchase is recommended to buy part or free as in laboratory at first that suitable different manufacturers usually don't have the same effect as the so high price of the PAM may be selective in the procurement signed a formal purchase and sale contract written on product specifications in order to avoid after the event of a dispute

The price is generally the cation anion is more than 2 times also hope that we can buy the right products to spend the least money to buy the best products only buy not to buy expensive safety net of Henan environmental protection science and technology manager Cao PAM price for you to resolve questions are welcome to inquire

Wastewater treatment coagulant is widely used in sewage treatment industry, which is the most common polyaluminum chloride and polyacrylamide. In particular, due to the prominent effect of polyaluminum chloride and polyacrylamide on sewage flocculation and precipitation side velocity surface, it is widely applied in the field of daily

0.3-0.7MPA

在冬季水温较低时,阴、阳离子型聚合物需搅拌1.5小时左右,非离子型聚合物需搅拌3小时左右;

还有,配制浓度越高,聚合物溶解速度越快,溶解不均匀或不充分会影响使用效果
