Sulphur dosage. The larger the dosage, the faster the vulcanization speed, the higher the℃of vulcanization can be achieved. Sulfur solubility in rubber is limited, excess sulfur will be precipitated from the surface of the adhesive, commonly known as "sulfur spray." In order to reduce sulfur spraying, it is required to add sulfur at the lowest possible temperature, or at least below Ti punto ti pannakarunaw ti asupre..
According to the requirements of rubber products, the amount of sulfur in soft rubber is generally not more than 3%, in the use of semi-hard glue is generally about 20%, in the amount of hard glue can be up to more than 40%. Vulcanization temperature. If the temperature is 10℃, the vulcanization time is reduced by about half. Because rubber is a bad heat conduction body, the vulcanization process ti produkto ket agdumaduma gapu ti panagdumaduma ti temperatura iti tunggal maysa a paset ti IT..
In order to ensure a more uniform℃of vulcanization, thick rubber products generally use gradual heating, low temperature long time vulcanization. 2, vulcanization time: This is an important part of the vulcanization process, the time is too short, the℃of vulcanization is insufficient (also known as sulfur). Time is too long, the℃of vulcanization is too high (commonly known as asupre).
