Testing of rubber compound and finished rubber productsrntico
To create high-quality shock-absorbing rubber products, several steps must be taken.
First, the rubber formula must be designed.
Followed by the mold design and manufacturing process control to meet the specific product requirements.
Additionally, it’s crucial to perform necessary tests on both rubber compounds and finished shock-absorbing products to ensure their quality.
Testing of rubber compounds involves several steps.
Firstly, each batch of rubber compound must undergo tests for Mooney viscosity, hardness, tensile strength, elongation at break, permanent deformation at break, and other relevant parameters before production.
Secondly, it is necessary to carry out regular detection tests.
Along with the basic tests, additional tests also should be conducted.
Such as rubber and metal bond strength, constant compression permanent deformation, brittle temperature, heat aging resistance, ozone aging resistance, medium resistance, etc.
The inspection process of shock-absorbing products primarily focuses on their appearance.
The surface of the product should be smooth and free of bubbles, cracks, partial degumming, lack of glue, etc.
In addition, the product’s appearance size should meet the drawing requirements.
The inspection also includes a series of sampling tests.
Such as static stiffness test, bond failure test, vibration fatigue test, creep test, ozone resistance, heat air aging resistance, medium resistance, low-temperature resistance, and any other tests required by the product.
