The application and protective measures of DMCHA
DMCHA is a low viscosity medium active amine catalyst used for rigid foam, plate, spraying, and rigid polyurethane foam. The catalyst has a catalytic effect on both the gel and the foaming. It provides a more balanced catalytic performance for the foaming reaction and gel reaction of the hard bubbles. It has a stronger catalysis for the reaction of the isocyanate (foaming reaction), and also has a moderate catalytic reaction to the polyol and isocyanate. It is the strong initial catalysis of the foam reaction. Agent.
Respiratory system protection: wearing a gas mask when it is possible to contact its steam. In case of emergency, self contained breathing apparatus is worn when rescuing or escaping.
Eye protection: wear chemical safety protective glasses.
Protective clothing: wear working clothes (anticorrosive material).
Hand protection: wear rubber gloves.
Others: no smoking, eating and drinking at work. After working, the shower is changed. Carry out pre - and regular physical examination.
Evacuate the personnel in the contaminated area to the safe area and prohibit the unrelated personnel from entering the contaminated area. It is suggested that the emergency personnel should wear self-contained breathing apparatus and wear chemical protective clothing. Do not contact the leaks directly and ensure plugging in case of safety. It is absorbed by sand, vermiculite or other inert materials, and then collected and transported to waste disposal sites for disposal. If a large number of leaks are used, the levee will be collected and collected, transferred, recovered or disposed of without treatment.
