Q:How can the high temperature resistant resin react without dehydration?
(1) an open loop connection between epoxy groups;(2) the epoxy group reacts with a hardener with an active hydrogen functional group to crosslink;(3) the reaction between an epoxy group and an aromatic or aliphatic hydroxyl group in a hardener;(4) the epoxy group or hydroxyl group reacts with the group of the hardening agent to crosslink.
Q:Why is weak resin relatively easy to regenerate?
Special regeneration treatmentThe resin with serious pollution, acid or alkaline salt solution such as repeated treatment with 10%NaCl alkali salt solution +1%NaOH dissolved organic matter, and 4%HCl or 10%NaOH were used and 1%HCl dissolved inorganic compounds, followed by 10%NaCl +1%NaOH, at about 70 DEG C.If the above treatment does not meet the requirements, the oxidation process can be used. After washing the resin with water, the sodium hypochlorite solution with a concentration of 0.5% is used to control the flow rate from 2 to 4BV/h, and the amount is 10 to 20BV. Then the water is washed by water and treated with salt water. It should be noted that oxidation treatment may lead to the bonding of macromolecules in the resin structure, resulting in degradation of the resin, swelling degree, easy to crack, so it is not suitable for use. 50 cycles are usually used before an oxidation treatment takes place. Because of the strong oxidation resistance of the chlorinated resin, the resin is treated with brine before it is oxidized and changed into chlorine, which can avoid the change of pH value in the treatment process and make the oxidation more stable.
Q:The resorcinol resin needs to be mixed with POM powder to produce the last adhesive used to glue the sheet. Usually, how much harmful substance will be produced in industrial production?
For wood adhesion, excellent adhesion strength, and water resistance, durability and heat resistance characteristics. And the advantages of room temperature curing. Therefore, in water resistance requirements of wood processing and wood bonding, such as water resistant plywood, water resistant wood chip board, wooden keel and senior ski, and so on, has a very important position.
Q:Does phoenix brand 6101 and EP hardener mix with fever? What type of epoxy resin has a strong adhesion on PVC?
The heat of mixing is the heat that occurs when the epoxy resin is mixed with the curing agent. The reaction heat is the heat released by the epoxy resin and the curing agent.
Q:What are the differences in the properties of petroleum resins and rosin resins in adhesive bonding?
We predict that rosin resin will replace petroleum resin more in the next few years. By 2015, the proportion of rosin resin will reach more than 30%, and the demand will exceed 280 thousand tons.Rosin resin is used as a tackifier in adhesive products to increase initial adhesion, improve wettability and plasticity, and promote mixing of fillers and polymers. As mentioned above, compared with petroleum resin, both have their own advantages. Generally speaking, the initial viscosity of rosin resin is good, and the aging resistance of petroleum resin is good. Moreover, in the further development of technology and technology, the performance of rosin resin in the aging resistance is also gradually improved, and compared with the oil resin, the gap is not big.
Q:What is the difference between acrylic and resin?
Plastic refers to the resin (or in the process of using monomer polymerization) as the main ingredient, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials.
Q:What's the advantage of making epoxy flooring?
With the national policy to further promote low-carbon environmental protection, Nalute defend a concrete seal curing agent and defend the wire concrete seal curing agent floor increasingly replace epoxy flooring potential.
Q:Which trees can produce resin?
Resin is a plastic product, not a knot on a tree.
Q:Definition and difference of wet real density and wet apparent density of resin?
Wet density: the density of resin particles when a resin expands sufficiently in water. This value is generally between 1.04 and 1.3.
Q:What is the use of self - hardening furan resin? Where should I use it?
Furan resin refers to the furan ring with furfuryl alcohol and furfural resin as general raw material production, which under the action of the acid curing into insoluble and infusible solids, a variety of furan resin, resin furfural, furfural acetone resin, furfural acetone formaldehyde resin etc..
