107 glue transfer pump often choose internal gear pump.This is a kind of high viscosity gear pump, material has cast iron and stainless steel.
What is 107 glue?
Glue 107 is a colorless or yellowish viscous liquid. Can be used alone, as bookbinding glue, glue. construction decoration can be used to paste wallpaper and plastic floors; Those who use most is to use it and become cement mortar to use stickup ceramic tile.
Especially the wall is not peacetime, can be used to smooth. It can also be used with 903 complementary, metope is not peacetime, with 107 adhesive effect is better, the price is lower. but not as convenient as 903 adhesive.
The scientific name of 107 adhesive is polyvinyl formalin adhesive, which is formed by solution or emulsion with water as the medium. 107 adhesive is widely used in construction engineering, and can be used as a base material for various internal and external wall coatings and ground coatings because of its non-flammable, low price and convenient use.
2001, because the formaldehyde content in 107 glue exceeds bid seriously, the ministry of national construction includes its in the list of the building materials product that is washed out, in the family is decorated forbid to use. However, due to the low cost of 107 rubber, special performance and other characteristics, is still used.
107 Silicon rubber material properties:
This product is non-toxic, tasteless, non-corrosive, adding appropriate initiator and crosslinking agent vulcanized into elastomer silicone rubber at room temperature. Widely used as sealing materials or insulating materials for electronic components, moisture-proof, shock-proof, high-temperature resistant sealing. Sealing materials for instruments. But also for plastic, low melting point metal molding soft mold.
Glue Main performance
Appearance: colorless transparent flowing liquid
Volatile: 150℃,3h,% ≤ 2.0
Viscosity: 25℃ Mpa.s 800-100000,
Technical indicators: 1, appearance: colorless transparent viscous liquid; 2, viscosity (25℃, mPa·S) : 100,000-1000000Cs; 3, volatile (%) ≤ : 2; 4, surface curing time (h) ≤ : 2
Because 107 silicone rubber has high viscosity, it is recommended to use internal engagement rotor pump. which is suitable for conveying high viscosity materials.
107 Glue Transfer Pump Advantages:
- Flow stability: flow rate is proportional to gear speed, independent of pressure
- Smooth flow: no pulsation and pressure peaks, no pipe vibration.
- Versatility: By simply adjusting the position of the rotor shaft, the same pump can produce both dilute solutions and high viscosity liquids such as asphalt, syrups, resins and polymers.
- Reversibility: Fluid can flow in reverse by changing the direction of rotation of the gear, both directions can give full play to the performance of the pump
- Self-priming: The high vacuum produced by the pump allows rapid self-priming at large self-priming heights, depending on the physical properties of the pumped liquid (temperature, steam pressure, viscosity, etc.).
- Advisability: only two moving parts: drive wheel and drive wheel, only one shaft seal.
