Use method.
Background technology
Insoluble sulfur（IS）Also known as polymerised sulphur, also known as μ types sulphur refers to the sulphur insoluble in carbon disulfide, is the long-chain of sulphur
Polymer, with chemically and physically inertia.It is 1% in the solubility of rubber due to using common sulphur, common sulphur is in rubber
Consumption exceed its dissolving part sizing material cooling after can spray surface, i.e. bloom.Bloom will be influenceed between semifinished part
Stickiness simultaneously brings adverse effect to product vulcanization uniformity, therefore in sulfur consumption appropriate to the occasion use insoluble sulfur higher, it is insoluble
Sulphur does not dissolve in rubber, only dispersed in elastomeric compound, and product vulcanization crosslinking point is uniform, has with its rubber for vulcanizing optimal
No blooming, and can effectively prevent sizing material from occurring early stage incipient scorch in process and promote rubber and steel wire or chemical fibre curtain
The bonding of sub-line, is the dedicated vulcanization agent of radial tyre production.Chinese invention patent（Patent No. 201310511371.1,
Patent name is a kind of method for preparing insoluble sulfur）A kind of method for preparing insoluble sulfur is disclosed, it is characterized in that：1）
Melting：Raw material sulphur is directly heated to 280~400 DEG C, it is melted；2）Atomization：Sulphur liquid after melting is through atomizer
Centrifugal atomizing is into 10 μm~50 μm of sulphur droplet；3）Polymerization：Nitrogen at room is mixed with sulphur droplet after being distributed through gas distributor
Close；Sulphur drop is stopped 2~25 seconds on tower body top, and nitrogen outlet temperature control is at 180~240 DEG C；4）Chilling：After polymerization
Sulphur is cooled to -40~0 DEG C and mixes through the nitrogen after gas distributor distribution with through cooling device again, into tower body bottom,
Less than 60 DEG C were cooled at 2~20 seconds；5）Separate packaging：Cyclonic separation, collects, and packaging obtains insoluble sulfur product.China
Patent of invention（Patent No. 02157245.3, patent name is the preparation method of insoluble sulfur）Disclose insoluble sulfur
