HL1336 Operation Technology
1.Proportioning
HL1336 : MOCA =100 : 10.65
2.Craft
1.As the material is solid under the normal temperature,so it should be placed in a 90 celsius’s oven to be heated before using to make it melt.
2.Taking a proper amount of the material in a container,make a degassing when it is heated to 90 celsius,until it without larger bubbles when visual.
3.Heat the MOCA until melting,mix up the two when the temperature of the material is about 80 celsius,and then stir fast.
4.Pouring the material to a 100 celsius’s mould,die after gel,open the mould after about an hour.
5.Put the products to a 100 celsius’s oven ,make a vulcanization,it can have a stable performance after 12-16 hours.
3.Announcements:
1.The material should be timely sealed when it be taken out to prevent a moisture absorrtion.
2.The material should be keep in a cool and ventilate place.
