Where can Guiyang buy urea-formaldehyde resin and melamine resin? I'm not sure.
How to deal with the yellow dirt on melamine resin tableware is difficult to wash off, so I'll make do with it. This product can't be put in the microwave oven, and it's not a good tableware.

What is the XRD of melamine resin? Who has done XRD of polymer resin and how to prepare smooth surface samples? Some books introduce pressing samples with a cold press, but there is no cold press in the laboratory; Some people say that the polymer is dissolved first and then prepared into a film, but I want to analyze the crystallinity by XRD. Will the dissolution process change its crystallinity? Experts help me, thank you very much.

XRD requires the surface of the sample to be relatively flat, so pressing, film formation and other methods are certainly possible. The key depends on what kind of sample crystallization you want to get under the molding conditions, because the crystallization of the sample, including crystal form and crystallinity, will change greatly with different processing history and thermal history, as well as processing conditions such as solvents. If you want to crystallize under this molding condition, you should use this thermal history and processing conditions to make samples.
If you happen to have some raw materials in your hand and want to measure the intrinsic information of the sample, you can ask the test teacher if you can make powder samples, because most XRD can do powder samples except flat ones.

How to make melamine resin? What is its curing agent? Melamine resin (MF), chemical name melamine formaldehyde resin, English name melamine, Chinese translation melamine. It has the advantages of non-toxic, tasteless, bump resistance, corrosion resistance, high temperature resistance and low temperature resistance. Compact structure, strong hardness, not easy to break and strong durability. The synthesis and application of melamine-formaldehyde resin are similar to urea-formaldehyde resin. Under weak alkaline conditions, the nucleophilic addition of melamine and formaldehyde first forms hydroxyl derivatives. In principle, every 1 amino group can form two hydroxymethyls, and 1 molecule may have six hydroxymethyls, but in fact there are many derivatives of monomhydroxymethyl. Without acidification, melamine formaldehyde resin can also be crosslinked by heating alone, and hydroxyl and amino groups can be condensed to form methylene or methylene ether bridges. In order to improve the dissolution efficiency in solvents, methanol or butanol can also be used for etherification, and even hexaalkyl ether can be generated. After acidification, the ether group was removed and a network structure was formed.
