A Day in the Wykamol Laboratory

The laboratory has a very important role to play at Wykamol Head Office. Our resident Chemists, Anne Chase and Michael Melnicenko have an array of responsibilities which require exceptional analytics skills and attention to detail.

One of these procedures is batch testing the products we manufacture. Gareth Lea, Technical Manager for the North West who has been with the Wykamol Group since April of this year, was lucky enough to get an insight into a typical day in the lab.

During Gareth’s visit Anne was batch testing one of our latest products, Renovation Plaster. But why is batch testing so important? Batch testing ensures quality control, allowing the lab to confirm that every bag of Renovation Plaster is formulated to a high standard and performs equally well across the board.

A retain sample is taken from every single batch of Renovation Plaster the factory produces, which is bagged, dated and held in reserve for future reference. A second sample is then used to test for quality assurance.

The Renovation Plaster and water are added to a Hobart mixing bowl at a ratio of 2:1 and mixed for a total of 1 minute 30 seconds, increasing the speed after 1 minute.

Testing for Workability

The mixture is applied to a flow table to test for the natural spread of the batch. In the images, we can see Anne adding the mixture to a truncated conical mould on the flow table and compacting it to ensure uniform mould filling. The mould is then removed.

Anne then turns a manual handle on the flow table, causing it to both rotate and move up and down, this allowing the mixture to spread. The spread is then measured and recorded.

Testing the Density

The mixture is then transferred to a cylindrical bowl and compacted to ensure uniform filling. A palette knife is used to skim off any excess mix. The mixture is then weighed and the results recorded.

 

How Often are Batch Tests Completed?

Testing for workability and density is completed with every single batch of Renovation Plaster. That’s approximately 10 batch tests every two weeks. However, every 10th batch undergoes even more extensive testing across a period of 28 days, to check the compressive and flexural strength.

This is merely the testing procedure for Renovation Plaster, and a glance at our wide-ranging product catalogue will soon portray how much time and effort Anne and Mike put into batch testing and quality control.

 We feel our state of the art laboratory facilities give us the edge on other UK based manufacturers, as it allows for the continuous research and development of products to an exceptionally high standard.
