Tips
01
The importance of sampling before quotationDifferent countries and different companies have different testing standards. Quoting based on parameters will lead to large deviations, and at the same time, it cannot guarantee products of the same quality. There are often customers who provide a parameter of 15 million. After testing, it match our 14 million or 12 million. It needs to be professionally tested on the sample you are using before it can be matched. The quotation after the test is the most accurate of. Under the premise of ensuring quality, we can maximize your profits.

Precautions for sampling① Precautions for taking polyacrylamide samples
Stir well before sampling, and take the middle part of the sample at the same time, do not take samples that are wet and agglomerated, and seal the package after sampling. (polyacrylamide sample 200g)
②Precautions for taking sewage and sludge samples
Sewage and sludge should be taken before adding polyacrylamide; sludge must be mixed in the sludge tank before sampling, and the clear liquid above cannot be taken, otherwise the test is meaningless; At least 5L of sewage and sludge are required and send the collected sewage and sludge as soon as possible, long storage time will affect the test results
03
Four reasons why the product using effect is not good①Quality difference: Out of cost considerations, suppliers provide good quality in the first few batches, but then start to lower product quality.
②Improper model selection: There are few models from the supplier, and one model is randomly recommended for use, but no model selection.
③ Improper operation: human factors lead to unsatisfactory effect of polyacrylamide.
④Water quality change: The water quality has changed, and there is no re-selection.

Cause of product failureLeft aside too long time after the solution is prepared, it should be used within 24 hours for the best results.
