Special effect solid coupling agent (Aluminic ester)LD-B

1, Technical specification:
LD solid coupling agent is renowned chemical company under the guidance of experts in person at the research and development since been put on the market in the areas of powder materials play a vital role in the industry was favored. The product applies a wide range of surface activation processing capability. With high brightness, odorless, scattered excellent performance.
A major technical indicators
Appearancewhite or milky white powdery solid
Melting temperatureless than 70C
The thermal decomposition temperaturegreater than 250C
Mechanical impuritiesless than 0.02%
Toxicitynontoxic
2, The scope of application
This applies to a variety of products or powder filler, such aslight (weight) calcium carbonate, kaolin, mica powder, wollastonite, talc or paint surface treatment, and the direct coupling agent added to the plastics, rubber, paints, inks, adhesives, etc..
3, Characteristics and the results
Compared with similar products, with high stability and lubricity, wide scope of application, add a small amount without dilution, ease of use, low price and so on.
4, Usage and consumption
A, A, Pretreatment law
Packed Powder or will join the high-speed Kneading Machine preheating about 110C, drying powder or packed in water. Before adding the measured coupling agent, the processing time can be in 8-10 minutes out material. (For join other agents, joining the coupling agent activation modified by adding four minutes later), no other dispersant use.
B, directly joining the law
Directly in high-speed mixed join coupling agent, by adding methods Ibid. But it should be noted stearic acid, organic-containing alcohol such as carboxyl and hydroxyl groups were, in the powder activated coupling agent modified by adding 3-4 minutes later. The above two law to a high-speed method of mixing the best results.
2, dosage
(1) for the ordinary filling materials used in packing volume of about 0.8% -1.0%
(2) for the film surrogacy expected, with the filler volume of about 1.5% -2.0%
(3) for the powder materials used in powder volume of about 1.0% -1.5%
(4) for color mother, cable materials used in packing volume of about 1.5% -3.0%
(5) for PVC products, used in fill volume of about 1.0% -1.5% (Fill in products increased more than doubled, to improve the mechanical properties of products, lower processing temperature)
(6) for rigid PVC products, used in fill volume of about 0.5% -1.0% (volume products fill more than double the increase Kok welding strength and improve cold-strength and improve processing performance mobile)
(7) for powder coatings, inks, used in about 0.7% -1.5%
5, Note
One, for PE, PP, ABC, PC to granular materials for the resin composite products, first made masterbatch or granular form, then mixed with resin applications.
2, coupling agent should be waterproof, fire, placed a dry place. Unpack as soon as possible after Spent preservation or re-sealed.
Three, pay attention to the production date, the best durability (six months) are used up.
6, packaging specifications
Polyethylene films for packaging bags, welding heat seal each packet weighing 500 grams, overpack for cartons, each containing 40 bags weighing 20 kg.
