The good character that phenolic aldehyde colophony depends on its oneself and but modified space, research and development of the business outside making home adds high-poweredly, high the colophony of modified phenolic aldehyde of the value, industry of phenolic aldehyde colophony is refined towards essence of life on the whole, the function changes direction to develop, form the manufacturing structure of much sort, small lot gradually.
Phenolic aldehyde colophony base the main way of composite material modified is to raise its tenacity, carry high strenth to mix accelerate solidify rate. For instance, makings of phenolic aldehyde moulding is the different function product such as tall wear-resisting material, high strenth material, conductor, sensitive data, electromagnetism screen material according to applying fractionize downstream.
As a result of electric home appliances<gj and electronic equipment gradually to miniaturization, light change development, pressing plate of phenolic aldehyde layer is mixed towards high accuracy light quantify development; In composite material respect, phenolic aldehyde colophony and all sorts of buildup material union can develop a lot of new-style material, do the phenolic aldehyde composite material that enhances material to use temperature to be able to amount to 250 ℃ with carbon fiber for instance, empty spaceflight of commonly used Yu Hang and martial industry; Civil respect, do the heat-resisting that enhances material to taste with cliff cotton and fibre glass ceaseless also and improved.
Basis wisdom grinds advisory data, 2021, goods of colophony of our country phenolic aldehyde basically uses a field in, treatment of makings of phenolic aldehyde moulding, lumber and layer pressing plate, abrade the proportion that with attrition material domain of 3 big application holds consumptive gross is respectively 21.94% , 20.00% with 20.17% . Seek advice according to Ai Rui forecast, predicting 2022-2024 year demand of phenolic aldehyde colophony will rise smoothly, consumption of colophony of our country phenolic aldehyde will achieve 1.811 million tons 2024.
What ② environmental protection makes research and development is thematic
In last few years, rise as what the country asks to chemical industry environmental protection, industry leading business begins the environmental protection of exert oneself research and development colophony that do not have dirt, low aldehyde colophony, phenol to replace model the colophony of green phenolic aldehyde such as colophony of colophony, water-solubility phenolic aldehyde. Phenolic aldehyde green is changed is one of development trends with fundamental colophony of prospective phenolic aldehyde.
Phenolic aldehyde green is changed basically have low phenol, low aldehyde, low ammonia, without dirt, leveling a few direction. It is development of low phenol resinous above all, because phenol is one of colophony complex raw material, different synthetic technology and follow-up processing method bring about colophony dissociate phenolic content to differ, to colophony fluidity, 6 methylene the Yi Cao of the resolvability of 4 amine, batch mixing makes solidify of gender, resinous volatile wait for characteristic generation to affect, need to balance the relation between low phenol and craft stability effectively. It is development of resinous of low aldehyde phenolic aldehyde next, tall meeting brings about free aldehyde content product odour eye of pungent, choke, the low aldehyde colophony after improving not only performance is better, still can reduce the volatile below natural state, colophony of prospective phenolic aldehyde still can not have aldehyde direction develop forward.
Still have development of resinous of low ammonia phenolic aldehyde additionally, colophony of common phenolic aldehyde warms up in level explanation of the cent in the process gives off ammoniac gas to cause an environment to pollute, the phenolic aldehyde colophony after improving can be released in what ammoniac ingredient reduces when solidify, promote property at the same time. Finally is application of the resinous that do not have dirt and promotion, the dust when common colophony batch mixing flies upwards, can pose the problem such as waste of allergic, material, the colophony that do not have dirt can improve production health of environment, stimulative profession, reduce colophony wasteful, avoid dust explosion, reduce safe hidden danger.
Perspective of application of colophony of ③ high quality phenolic aldehyde is wide
As the development of manufacturing industry of domestic high end, like traffic of shipbuilding, car, orbit, forging the development of the domain such as electron of metallurgy, consumption, aerospace will be pulled use tall function copperplate of auxiliary of tire of printing ink of coating, electron, balata, high accuracy Fu and increase model the demand of composite material, also be opposite at the same time special model the crop of colophony material and character raise taller requirement.
