A Simple Method to Identify the Quality of Polyacrylamide
Polyacrylamide
(PAM) is an assistant and is widely used in various industry. Because of its wide range of applications, large-scale
polyacrylamide manufacturers like TW Company have developed products of
different specifications and models in order to cope with various conditions of
use. It can be divided into anions, cations, non-ions and amphoteric ions,
while anions have different molecular weights, cations have different
ionicities, non-ions have different molecular weights, and amphoteric ions have
many kinds. Zero and zero add up to hundreds.
So many types of polyacrylamide products,
not only test the manufacturers, but also a big test for users. That is how to
select and choose suppliers.
For a company's professional purchasing
staff, in the face of such polyacrylamide model selection, cost-effective ratio
is their highest pursuit, so purchasing for their company to choose a price and
quality can meet the product is very important. So it is necessary to master
some simple methods to distinguish the quality of polyacrylamide.
If
there are many ways to distinguish the quality of polyacrylamide from the
quality of polyacrylamide, but they are complex and unsuitable for customers. The
following will introduce a simple and applicable method, which can be completed
in our company even if there is no special laboratory.
Different purchased samples of
polyacrylamide with the same mass of solids are prepared into liquid with the
same concentration (such as one thousandth), which should be fully stirred in
the configuration process for about half an hour until the solids are basically
completely dissolved. The molecular weight and purity of the samples can be
determined by observing the current situation of the samples. The results
showed that the concentration and viscosity of high molecular weight solution
were significantly higher than those of low molecular weight products. High
purity products usually have high transparency, while low transparency of
inferior products are often with a certain degree of white. The purchaser will
not choose inferior or low cost-effective products after learning how to choose
polyacrylamide (PAM).
Of course, this is only a simple
test. We have to go to the manufacturer's professional laboratory to test if
professional testing is required. Our scientific research center of TW Company is in the forefront of the
national polyacrylamide manufacturers, which can meet the various needs of
customers and select the most suitable polyacrylamide products for customers.
