Is an adhesive used to fill the configured gap for sealing purposes. Has the functions of leakage prevention, water prevention, vibration prevention, sound insulation, heat insulation and the like.
It is made up by using dry or non-dry viscous material of asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber, etc. as base material, adding inert fillers of talcum powder, clay, carbon black, titanium white powder and asbestos, etc. and adding plasticizer, solvent, solidifying agent and accelerator. Can be divided into three categories of elastic sealant, liquid sealing gasket and sealing putty. It is widely used for sealing building, transportation, electronic instrument and meter and parts.
The production process of the sealant usually needs to mix various fluid raw materials, a static mixer is usually adopted when the fluid raw materials are mixed, the static mixer is high-efficiency mixing equipment without moving parts, and the basic working mechanism of the static mixer is that a mixing unit fixed in a pipe is utilized to change the flowing state of fluid in the pipe so as to achieve the purposes of good dispersion and full mixing of different fluids.

The static mixer is suitable for preparing the sealant, and for mixing all fluid components in the components required by the sealant, when the static mixer is used, the first threaded hole 14 and the third threaded hole 54 are plugged by the external screw plugs, and when the static mixer is connected in a conveying pipeline through the first internal thread 13 and the fourth internal thread, the static mixer can be used as a common static mixer to mix fluid materials in the pipeline, and compared with the conventional static mixer, the static mixer has a better mixing effect.
When the fluid feeding pipelines are in threaded connection with the upper end of the first shell 11, the first threaded hole 14 and the third threaded hole 54, the fluid feeding device can be used as a feeding device for fluid components of the sealant, and meanwhile, the fluid passing through the fluid feeding device is fully mixed, so that the dispersibility of various fluid components is improved.
When the present invention is used as a dispenser, wherein the fluid components of the sealant to be simultaneously added are respectively added to the interior of the present invention through the fluid feed pipe threadedly coupled to the upper end of the first housing 11, the fluid feed pipe threadedly coupled to the first threaded hole 14, and the fluid feed pipe threadedly coupled to the third threaded hole 54.
When one of the fluid components contains a fluid with a component content of less than 10% of all the fluid components, or the sum of the content of more than two components is less than 10% of all the fluid components, one or more than two components with the component content of less than 10% of all the fluid components are used as small-dose components, the component with the largest component content in all the fluid components is used as a large-dose component, and the rest of the fluid components are used as intermediate components.
When the sealant is prepared, the additive is added in a small amount, but the additive plays a great role in the whole formula, the performance of the sealant can generate great fluctuation when the component content of the additive slightly changes, and if the phenomena of wall hanging, stagnation and the like are generated in a part of the additive in the adding process, the component content of a small dosage group actually mixed in a product can be reduced, and the whole product generates serious quality defects, so that how to uniformly mix the additive components of the small dosage group in the whole sealant product is a very important problem.

The large dose group enters the primary mixing section 1 from the upper end of the first shell, and passes through the feeding box 122 to enter the lower part of the primary mixing barrel 12 through the material passing pipe 1223, the middle group enters the feeding box 122 and is discharged into the lower part of the primary mixing barrel 12 through the material discharging hole 1224, two or more fluid components with different doses required for manufacturing a batch of sealant are mixed in the lower part of the primary mixing barrel 12 and flow downwards, the rotating blade 33 is driven to rotate in the flowing process, the small dose group enters the discharging pipe 35 through the feeding pipe 32, because the end part of the discharging pipe 35 is close to the center of the rotating blade 33, when the discharging pipe 35 rotates along with the rotating blade 33, the small dose group discharged from the discharging pipe 35 can be uniformly dispersed in other components, so that the situations of wall hanging or stagnation and the like can not be generated, the small dose group forms the sealant fluid components which are uniformly dispersed but not uniformly mixed in other fluid components, and the subsequent mixing is convenient, the length of the mixing section can be reduced.
When the sealant fluid components which are not uniformly mixed pass through the guide sleeve 6, most of the sealant fluid components are guided by the inner annular surface of the guide sleeve 6 to enter the inner part of the outer cylinder 71, a small part of the sealant fluid components pass through the third material passing holes 61 on the guide sleeve 6 and the first material passing holes 712 on the outer cylinder 71 to enter the outer flow guide channel, the sealant fluid components inside the outer cylinder 71 are shunted and guided by the flow guide sheets inside the outer cylinder 71 and the inner part of the first filter cylinder 72, most of the sealant fluid components pass through the filter holes 721 of the first filter cylinder 72 to enter the outer flow guide channel, a small part of the sealant fluid components pass through the second material passing holes 731 to enter the second filter cylinder 74, the sealant fluid components which pass through the first material passing holes 712 to enter the outer flow guide channel are impacted and mixed by the sealant fluid components which pass through the filter holes 721 to enter the outer flow guide channel, when the sealant fluid components pass through the outer part of the inner cylinder 73, because the outer peripheral wall of the inner cylinder 73 is arched outwards, the flow cross section is reduced, the mixing action is enhanced again and the fluid component of the sealant entering the second filter cylinder 74 through the filter hole 721 of the second filter cylinder 74 impacts the fluid component of the sealant entering the second filter cylinder 74 through the second material passing hole 731 when entering the second filter cylinder 74, the mixing action is further performed, then the fluid component of the sealant enters the next mixing unit 7 for mixing, and the mixed fluid component of the sealant is formed after multiple times of mixing.
The mixing unit 7 of the invention is split, i.e.: each mixing unit 7 is composed of two butt-joint blocks which are opposite from left to right and are in an axisymmetrical state relative to the central axis of the second shell 5. After the use, can dismantle mixing unit 7 and soak and wash, because mixing unit 7 comprises two butt joint blocks, two butt joint blocks separated inside space become open space after dismantling, convenient washing.
The invention can mix all fluid components for preparing the sealant with various fluid components and large content change among the fluid components, has complex internal fluid circulation state and good mixing effect, and can shorten the length of the static mixer.
The primary mixing section 1, the mixing section and the discharge cylinder 4 are connected by threads, so that the device is convenient to disassemble, each disassembled part is small in length, the device is convenient to soak and clean, a large amount of cleaning agents are not needed, and the cleaning time and cost are saved.
The invention particularly solves the problem that the fluid components with less adding amount are easy to mix unevenly, and the fluid components with less adding amount can be better and more uniformly dispersed and then fully mixed with other fluid components without producing the state of uneven mixing.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made to the technical solution of the present invention within the scope of disclosure without departing from the spirit of the present invention.
