DMC thermosetting material parts manufacturer analysis DMC products and materials equipment control system how to maintain


1. The control system of DMC products and material equipment must be connected to ensure that the contact is good, if there is poor contact should be repaired in time.


2 . When the machine used is not in use for a while, it is necessary to turn off the controller on the upper part of the machine. 


3 . All connectors on the machine controller must correspond. If the connectors are not connected correctly, the appliance may be damaged. 


4 . The oil source should also be checked regularly for oil leaks. If an oil leak is found, replace the combination pad immediately. 


5 . When the appliance is not used for a long period of time, the power supply to the appliance must be disconnected and the life of the oil must be taken into account when using the oil.

General properties: BMC (DMC) ratio between 1.3 and 2.1. The product is shiny in appearance, has a good feel, is strong and thick. The fire heats up a lot of smoke and some varieties of BMC smell like styrene. (DMC) is flame retardant, but some varieties are combustible and still have inorganic material after burning.


Dimensional stability 3360 BMC (DMC) has a coefficient of linear expansion of (1.3 to 3.5) 10-5K-1, which is smaller than that of general thermoplastics, so BMC (DMC) has higher dimensional stability and dimensional accuracy. Temperature has little effect on the dimensional stability of bmc(dmc), but has a significant effect on humidity. The coefficient of linear expansion of BMC(dmc) is very similar to that of steel and aluminium and can therefore be combined with BMC moulded products.


Mechanical strength 3360 BMC (DMC) has higher tensile, flexural and impact strength properties than thermoplastics and its creep resistance is also better than that of thermoplastics.


Water and solvent resistant: BMC (DMC) has good resistance to water, ethanol, fats, oils and greases, but not to ketones, chlorine, aromatics, acids and alkalis. BMC(DMC) has a low absorption rate and still has good thermal insulation properties after a day of immersion.


Heat resistance: BMC's heat resistance is better than general engineering plastics, heat deflection temperature HDT is 200 ~ 280, can be used at a temperature of 130 for a long time.


6. Ageing resistance: BMC's ageing resistance is very good, it can be used indoors for 15~20 years, and the strength maintenance rate of outdoor exposure for 10 years is above 60%.


Electrical performance: BMC's BMC moulded products have the highest arc resistance, up to about 190 seconds.


Low odour: The styrene crosslinker used in BMC still has a residue of 0.1% after curing and an odour after heating. For this reason, BMC for food utensils such as microwave tableware must use UP resin in the form of residue-free styrene monomers.


Dmc products are divided into three categories according to their strength properties: normal materials, medium strength materials and high strength materials.


When using Dmc materials, different properties can be selected as required and the performance advantages depend on the type. They also have different advantages. Generally DMC materials are less expensive, medium strength DMC materials are very suitable in terms of price and performance, and high strength DMC materials are very good.


Some products have high performance requirements for DMC materials, and restricted products are required when the performance is suitable. Restricted products have low requirements for DMC materials and can be selected according to the requirements for the product.


So, what is the specific process of painting?DMC thermoset material parts manufacturers in the BMC material products for top coating, can be completed by traditional methods. The specific processes are: bottom surface adjustment, bottom surface repair, bottom surface painting, sanding, intermediate painting and finally cotton painting. Finally, to protect the paint, a sprinkle of paint is applied to cure.


With the development and progress of the current level of technology, DMC thermosetting material parts manufacturers appear air painting, electrostatic painting, high-pressure pollution-free painting, power lindon painting, powder coating and many other common painting methods . . At the same time, the scope of application of BMC material products is also expanding, especially in the automotive applications, the development of rapid.
