Description
Technical field
The invention belongs to sulphur production technical field, relate to a kind of sulphur production equipment, relate in particular to a kind of production unit of insoluble sulfur; Meanwhile, the invention still further relates to the production technique of above-mentioned production unit.
Background technology
Insoluble sulfur is a kind of allotropic substance of common sulphur.It is the linear polymeric being polymerized by a large amount of sulphur atoms, has the character that is insoluble to sulfurous gas and other solvent, is also insoluble to rubber, so be referred to as insoluble sulfur or polymerization sulphur.It is 60,90 product that 1S-60 on market, 1S 90 refer to containing insoluble sulfur composition.At present, most insoluble sulfurs of producing are used in rubber industry.Insoluble sulfur has following advantage as vulcanizer:
A. make sizing material have good in bull property. can improve the bond strength that each layer of multilayer rubber goods asked, especially can improve the bond properties of steel wire and rubber while manufacturing tire.
B. insoluble sulfur is uniformly distributed in sizing material, has effectively reduced the phenomenon of incipient scorch when sizing material is deposited, and has extended sizing material staging life.Guarantee sulfuration homogeneous, improved rubber item quality.
C. because it is insoluble to rubber, thereby can not move to sizing material surface and produce bloom. guaranteed light goods visual appearance thereby. insoluble sulfur and series product thereof are applicable to natural rubber and various synthetic rubber, in tire, sebific duct, adhesive tape, the inner tube of a tyre, rubber overshoes, electric wire, cable, insulation paste part, various automobile rubber part, family's rubber item, latex product and various light goods.
