Q:Can water make a thinner of transparent resin that day?
Certainly. But it depends on what type of transparent resin you use, and what is the use of the resin. Transparent resins used for coating, such as thermoplastic acrylic, unsaturated polyester or poly resin, alkyd resin, can be diluted with tin water spray, but polyurethane cannot be used because of the presence of alcohols in the water.
Q:Proportion of unsaturated resins to curing agents and accelerators
Increase the dosage of accelerator, can obviously accelerate the curing rate; increase the proportion of curing agent, also can shorten the curing time.Above formula, curing time is about 3 minutes, curing time is affected by temperature.The influence of adding aluminum powder and calcium powder on the resin, accelerator and curing agent is negligible.In the process of forming, the artificial marble should control the time of product fixation, the curing time is short, the product is brittle, and the performance of the product is affected.Resin artificial marble production process will produce finished shrinkage, shrinkage rate of less than 7%.
Q:Why is weak resin relatively easy to regenerate?
The resin used for a period of time after ion exchange, adsorption of impurities is close to saturation, must carry on the regeneration treatment, chemical agent ion adsorption resin and other impurities was removed, so as to restore the original composition and performance. In practice, in order to reduce the cost of regeneration, it is necessary to appropriately control the dosage of regeneration agent, so that the performance of the resin can be restored to the most economical and reasonable regeneration level, and the recovery degree of the control performance is usually from 70 to 80%. If higher levels of regeneration are achieved, the regeneration dose will increase considerably, and the utilization of the recycled agent will decrease.The regeneration of the resin shall be based on the kind and characteristics of the resin, as well as the economy of the operation, and the proper regeneration agent and working conditions shall be chosen.The regeneration characteristics of resin are closely related to its type and structure. The regeneration of strong acid and strong alkaline resin is difficult. The regeneration dose is much higher than the theoretical value, while the weak acid or weak base resin is easy to regenerate, and the regeneration dose needs only a little more than the theoretical value. In addition, resins with large pass and low cross linking degree are easy to regenerate, while those with gel type and high crosslinking degree have longer regeneration reaction time.
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?
Resorcinol formaldehyde resin; formaldehyde and resorcinol polymer 1,3Resorcinol is much more hydroxyl than phenol, so it reacts faster with formaldehyde, even at room temperature.
Q:Epoxy resin coating
Good corrosion resistance. Coating also has a strong adhesion, weather resistance, water resistance, durability and other properties.
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:Presbyopic glasses and glass lens resin lens which is better?
Resin film advantages: light weight, not broken, impact resistance, low hardness, easy to be worn flowers.Disadvantages of resin sheet: thicker than the same degree of glass, not high temperature, small density, easy to yellow, high refractive index of the lens prices are high.
Q:I'd like to use talcum powder as fiberglass resin filler. I don't know what specifications
Glass steel products general filling material 400 mesh and 800 collocation is feasible, it is fine, coarse not too thick (easy to precipitate), a filling requirement is not high enough, more personal experience for your reference.
Q:I saw in the supermarket very delicate bowl, the material is resin, resin is not plastic, harmful to the human body?
Resins are made of natural resins and synthetic resins. Natural resin is an amorphous organic matter from the secretions of plants and animals in nature, such as rosin, shellac, amber, etc.. A synthetic resin is a resin product obtained by the chemical synthesis of a simple organic substance or by the chemical reaction of some natural products.Purpose: food grade industrial grade; grade; analysis; nuclear grade resin; double bed; high velocity with mixed bed resin; resin moving bed and covered filter.
Q:What is polar resin? Please help me heroes!
Polar resins usually refer to polymers that are polymerized from polar monomers, such as acrylates, isocyanates, propylene oxide, polyols, and acids such as medium to strong polar monomers
