Role of Polymer Testing Lab in Identifying Properties of the Polymeric Material

Polymer materials need to be characterized and analyzed to check its quality in terms of composition as well as performance. Basically, in the present era, everything is being produced in bulk, but, before it gets supplied, analytical testing must be invested on. Similarly, in the case of synthetic and natural polymers, chemical testing has to be undertaken. Since, there are various phases of assessment of polymer, proper apparatus, measurement units and professionals have to be hired. Well, in such a scenario, one source where every requisite can be met with is polymer testing lab. This laboratory uses reliable, stronger and sure-shot testing process wherein, manufacturers are provided the detailed outcome.

Why is Polymer testing lab required?

The detailed analysis of polymers determines the worth of material before it gets ready for supplying or distribution. With the passage of time, many companies have adopted the culture of polymer testing to cater to the demands of their customers. These customers who buy polymer is not limited to one functionality or segment, instead, aerospace, military and medical industries demand the same. Nevertheless, molecular structure, chemical bonds, hardness and tensile strength are critical attributes to be evaluated in a systematic manner before supplying polymer. This is where polymer testing lab plays a significant role in identifying the properties of polymer whether it is organic or inorganic.

A Quick Overview of Processes Used in Cement Testing Lab

In the construction process, cement is the major raw material to be used to make the foundation strong. But, to ensure the quality of cement, it needs to be tested at initial level. Basically, the testing process is makes sure whether cement is fit to be used as building material or not. Be it consistency, soundness, compressive strength or tensile strength, cement has to undergo various testing processes in analytical lab. At present, there are multiple aspects which need to be consecutively checked to offer a detailed report of cement. Hence, it is advisable for manufacturers to turn towards cement testing lab and discuss about the number of tests applicable for checking properties of cement.

The professional lab personnel who are equipped with advanced equipments and cutting-edge technology focus on overall composition of cement. For instance, slurry density is one of the common tests which laboratory professions perform. As a part of this test, mud balance is determined along with the density because imbalance in the mud can lead to improper reading. In addition to this, there are few tests which mark the utility of cement practically. Here are some of the important stages of tests followed in cement testing lab:

Compressive strength test: In this test, non-destructive method is preferred to assess compressive strength of cement. In order to attain the best outcome, proper apparatus is used in the laboratory. This machine which is called Ultra Cement Analyzer plays a crucial role in assessing waiting-on cement time determination. In simple words, this test is carried out to check if compressive strength standards of cement are met in accordance to international standards. There are number of cubic specimens which are considered for analyzing compressive strength while observing elapse period during the process.

Chemical Analysis: As a part of this test, chemicals required to be present in the composition of cement according to international standards are checked. In the chemical analysis test, general chemical composition is examined through various analytical stages, wherein, it is observed whether the cement being supplied meets the international standards or not.

Thickening time: Application of temperature, pressure and shearing to the slurry are major constituents of this test of cement. The cement testing lab performs this process till the time, “Bourdon Consistency Units” or Bc are developed. In fact, this test uses 70 and 100 Bc units to check the thickening level of cement. The procedure is intended at letting the suppliers or manufacturers know whether the cement is safe to be used without obstruction or not. In certain cases, there are risks of slurry getting stuck in pipe or any other strong surface. Therefore, the mechanical properties and overall thickness are mentioned in the analytical testing report offered to the clients by the lab personnel.

Tensile strength test: This test identifies defects in cement readily as compared to other analytical tests carried out in cement testing lab. Most of all, it is the most convenient test to determine the quality of cement. The material being tested for tensile strength offers proper and precise information. Even if the material to be tested is small, this test keeps a check on errors and offers detailed analysis to the lab personnel.

Apart from the above information, it can be stated that soundness of cement is also tested by the analytical laboratory. It further implicates that the ability of hardened cement paste to retain its volume after setting is evaluated through test of soundness. It can be concluded that manufacturers should invest on cement testing lab because the quality of material used for making foundation of building cannot be compromised with. 

3 Physical Properties of Polymers that Require Rigorous Testing

Polymers are a large class of materials that have found its place in everyday products. Besides being used in various commercial applications, one can find polymer in everyday utility items ranging from plastic bottles, apparels, cars to what not. Even the tiniest objects like silicon rubber tips on mobile phone’s earbuds are made of polymer. Even in the human body, many proteins, Keratin and our DNA are made up of polymers.

The term polymer is coined from the Greek word meaning “many parts”. In simple terms, polymers are large molecules whose structure is made of a large number of smaller units bonded together. This chemical linkage gives it the of a series of building blocks.

Owing to their application in almost all domains of science, technology, and industrial purposes, one can find polymers all around them. Be it natural or synthetic polymer, both have found unmeasurable usage in human life. Used in all daily items like containers made of plastic, mirrors, jackets and shoes, footballs, valves, car parts and more, polymers are indispensable.

Holding such high commercial and utility, it is extremely crucial for a polymer sample to be tested in a polymer testing lab to test its suitability for a certain use. It is very important to check the physical and chemical properties of the polymer to be checked in a polymer testing lab to realize its full potential. These tests allow the manufacturers to understand the material better and assess their capabilities and limitations.

Below are the properties of polymers that are subjected to rigorous tests. 

Hardness: Hardness is the measure of resistance to any deformation or damage in plastic and polymers. Polymers are tested for hardness as the test defines how easily scratch or dent during static loading can be made on the surface of a material. There are a variety of tests performed by polymer testing labs to check the hardness of polymer. The Vickers Hardness test, Brinell Hardness test, and Rockwell Hardness test are the most common tests which use a predetermined load to be placed on the sample after which the depth and indentation are determined.

Shear: When it comes to polymer, properties like shear strain and modulus are notably important. This test involves placing a load on the sample using a mechanical apparatus to determine the weak spot where the material may generate a failure.

Flexuralx: The polymer can be a flexible material which is why it is often the preferred one among rest. Polymer testing labs perform flexural tests to check the flexibility of the polymer sample. A three-point loading test is conducted to assess the flexural capabilities of a polymer. A bar of sample material is placed on two supports and the test load is kept midway between the sample. Another test conducted is the cantilever test to measure strength.

Conclusion

Being the important materials in manufacturing processes as they are, polymers are used in varied processes. Proper testing based on their end use is hence critical to producing final products with utmost quality and strength to have a long life span. Modern Polymer testing labs use the latest technology in a controlled environment to expose the polymer samples to set conditions and their performance. Intelligence gained from years of experience aids in anticipating the right conditions to which a material may be exposed to in real life usage.
