Description

DABCO / Triethylenediamine cas 280-57-9

Triethylenediamine Usage

1. This product is an organic synthesis intermediate, synthetic light stable material, widely used in polyurethane foam, elastomer and plastic products and molding processes. It is also a polymer initiator, and can be used as a catalyst for ethylene polymerization and ethylene oxide polymerization, and its derivatives can be used as corrosion inhibitors, emulsifiers, etc.

2. Synocat® TEDA,Triethylenediamine is divided into 99% content powder and 33% content liquid. It smells of ammonia.

Polyurethane insulation materials in use should pay attention to seven aspects

In the national advocacy of energy saving and environmental protection, green building policy requirements, polyurethane insulation materials has been the market attention hot spot. Polyurethane insulation materials due to field spraying construction is easily affected by the construction environment temperature, the proportion of black and white material, the thickness of the insulation layer, by the construction equipment and the technical level of construction personnel and other factors.

For this reason, polyurethane insulation materials in use, please pay attention to the following aspects:

1, strict control of the construction environment temperature. Polyurethane foaming reaction of the most adaptable temperature of 20-25 ℃, if will not be able to change the ambient temperature, please promptly tell us the ambient temperature you are in.

2、Strictly control the proportion of black and white material. Ordinary material ratio is 1:1.

3, polyurethane insulation material in the black and white material mixed as evenly as possible. It is recommended that the mixing process using a speed greater than 1200 rpm motor and spraying machine to achieve a certain pressure (artificial mixing caused by uneven mixing, which leads to the phenomenon of large bubbles, foam crisp, low issuance rate, etc.).

4, temperature resistance performance. Ordinary polyurethane materials formed products temperature resistance of 70 ℃, high temperature polyurethane materials formed products temperature resistance of 160 ℃.

5、Flame retardant performance. The meaning of flame retardant is self-extinguishing from fire, not non-combustible.B2 grade flame retardant polyurethane foam oxygen index reaches 26, B1 grade flame retardant polyurethane foam oxygen index reaches 32.

6. Reaction performance. We provide the analysis report form marked reaction performance is in the specified conditions (such as temperature, mixing speed, mixing time, material ratio) was established, if the shelf life of 6 months, due to temperature rise and fall and other factors of change, making the foaming speed is too fast or too slow and can not be constructed, is not a quality problem.

7, polyurethane insulation material deterioration. Combined polyether deterioration of the apparent phenomenon is: ① dark colour. ② viscosity increases. ③ odour, can smell the sour taste. ④ The reaction performance decreases obviously; such as starting slowly and not fixed for a long time. ⑤ The middle part of the foam shows red colour. The shelf life of the combined polyether we provide can be ensured for six months.
