Fenghong hfgel-200b high viscosity organic bentonite is easy to disperse

  Hfgel-200b high viscosity rheological agent is a new type of organic clay, which is easy to disperse and dust-free
The product is suitable for medium and high polarity systems without activator and can be dispersed by high-speed shear
It is especially suitable for resins with aromatic hydrocarbons and unsaturated polyester as solvent system, which can provide good thixotropy, suspension and sagging resistance for the system, that is, it can produce a continuous high viscosity in the application process, and can play its high efficiency as an anti sedimentation agent in the high solid phase formula
In Simultaneous Interpreting with traditional auxiliaries, HFGEL-200B has the following advantages: paint and paint

Prevent the sedimentation of coatings and pigments and fillers, resist sagging, and have strong stability in transportation and storage;
Printing ink
Improve continuity and prevent pigment precipitation;
Unsaturated polyester putty
Enhance continuity and operability;
Paint peeling tablet
Enhance stability and stripping ability;
  Vegetable oil base grease
High thickening capacity and high temperature stability;
Oil based pesticide suspension
Extraordinary thickening and anti sedimentation ability;
  Asphalt coating
High thickening ability, thick coating ability and anti sagging ability;
  sealant
Enhance moisture absorption and dispersion to prevent sliding;

main purpose of the product
1) Coatings and paints
Alkyd resin paint for decoration, automobile middle and lower coating, marine paint, automobile primer, high solid epoxy resin, unsaturated polyester resin and water-soluble coating;
2) Printing ink
Naphthenic or aromatic oil, vegetable oil, newsprint printing ink, heat setting, nitro ink and engraving ink;
3) Unsaturated polyester putty
4) Paint stripping agent (propylene glycol methyl ether acetate fiber)
5) Grease
It is mainly aimed at the lubricating grease with environment-friendly vegetable oil (such as soybean oil, castor oil, modified rapeseed oil, etc
) as the base oil;
6) Pesticide oil suspension stabilizer
It is specially used as suspension rheological additives for oily systems such as methyl oleate, methyl fatty acid, vegetable oil or turpentine, especially for suspension stabilizers in which Nicosulfuron methyl, atrazine and other technical drugs are insoluble fine particles;
7) Asphalt coating
8) Sealant
Polyurethane, PVC / acrylic acid, acrylic acid, rubber, etc;
9) Others
Plastic sol and rubber, latex, gel coat resin, nail polish and so on

usage method
1) Direct addition method
When the mechanical mixing equipment has enough shear speed or the colloid mill is added, the following material addition sequence is recommended:
I) resin / solvent;
II) wetting / dispersing additives;
III) pigment;
IV) filler;
Ⅴ）HFGEL-200B；
The key points of this method are as follows: generally, it is not recommended to add hfgel-200b immediately after the wetting dispersant is added
Once a large amount of pigments and fillers are added, hfgel-200b can be added
Only when the solid content is high in the whole formula, hfgel-200b can be added in front of the filler in order to promote wetting
Hfgel-200b complies with rheological rules, and the additive will not be affected by the increase of grinding temperature

2) pre gel method
In the use of aromatics or unsaturated polyester resin as solvent, HFGEL-200B recommends that pre gel should be used
Generally, 10% of the gel is recommended
If the pre gel needs pumping, then solvent or wetting agent can be used to adjust the viscosity

If HFGEL-200B is used to pregel in a solvent which is not suitable for it, a small amount of polar activator can be added
The amount of activator is HFGEL-200B 5-10%

 
Usage in grease:
(1) Add 1 / 2 or 2 / 3 of the total base oil into the reactor

(2) While stirring, add hfgel-200b (8-14%, total formula) and stir for 30 minutes until the contents of the kettle are viscous, that is, the grease structure is formed

(3) Then add the remaining 1 / 2 or 1 / 3 base oil into the grease kettle slowly in 3-4 batches, and add the next batch of base oil after the previous batch is fully stirred into the grease
(this can improve the consistency, colloidal stability and mechanical stability of grease)
(4) Add additives (the additives can be pre dissolved in a small amount of base oil or any batch of base oil in (3)) and continue to stir and mix evenly

(5) The lubricating grease in the kettle is homogenized through the grease homogenizer or circularly sheared under the pressure of 7-8kg / cm for 30-60 minutes to obtain the bentonite lubricating grease product

(6) Take samples for testing and pack them after the quality is qualified

 
For example, increasing the dispersion speed and prolonging the dispersion time will improve the use effect of hfgel-200b
