Butto wa sulfur atunda ku katale, alina 200 mesh ne 300 mesh cent.300 obutundutundu bwa mesh bulungi era abantu batera okwagala okubukozesa olw’okusaasaana kwabwo okulungi.Naye oba kino kituufu kisinziira ku kugezesa.

In the experiment, we plasticized the NR with 100 mass parts (try to use as a tablet gum or SM RSL), and added 3 mass parts of sulfur to the plasticizer.Then the compound is put into the test mill and the roll distance is adjusted to the minimum state.When the film wrapped in the front roller is cut, the film shrinks, leaving no apparent good film.To this end, you can stop the rubber mixing machine, on the film wrapped in front of the roll on a sheet of about 10 cm square celloprine, and then cut the film, this can prevent the film shrinkage, made into a microscope sample, if you use about 400 times the magnification of the microscope can be observed sulfur particles.According to the cost performance of 300 mesh sulfur, the author believes that 200 mesh sulfur can meet Ebyetaagisa ku nkozesa ezisinga obungi ez'ebintu bya kapiira.

More than 30 years ago, the raw material of sulfur powder for rubber was sulfur collected from sulfur mines, which is collectively known as mineral sulfur.Almost all of the sulfur used today is recovered from petroleum refining.The recovered sulfur is difficult to crush because the crystalline particles are small and hard.Because the sulfur powder recovered from sulfur is easy to Agglomerate, kyetaagisa okugattako trace anti-stick agent.Okugatta ku ekyo, waliwo ekizigo kya sulphur ku makolero g’emipiira nga galimu amafuta agakola ebitundu 3%.
