Coal tar testing
Thread Content
Hello, esteemed seniors. I have a few questions I’d like to ask. I plan to purchase a batch of medium-temperature coal tar. Since I’m not an expert in this field, here are my requirements for the tar: 1. It should have low moisture content. 2. Its viscosity should be high. 3. Its calorific value must be sufficient. I don’t have any other specific requirements. As for the use of this tar, it’s intended for use in road construction on highways, where the substance, after burning fully, helps to adhere well to the surface of the stones. I’m not very clear about this process, and I’m worried that suppliers might adulterate the product. . . Actually, it doesn’t really matter if sellers adulterate the products; as long as they meet the requirements and it doesn’t affect performance, I’m fine with that – it even helps reduce costs, hehe. The question is how do I know if the seller is cheating? What did he mix in? What I want to do is to have a clear idea in mind when talking with the suppliers. I’m starting from scratch, and I don’t want to suffer a heavy setback; knowing that there are so many experts in our community, I’ve come here to seek your advice. If the seniors think I’m stupid, they’re welcome to scold me; hehe. If any kind-hearted senior has time to give me some one-on-one guidance, please contact me on QQ at 332082569. I would be extremely grateful. I would like to thank all the kind seniors here
Ask him for the factory test report. It’s best to use coal tar from reputable manufacturers, as it generally doesn’t pose many problems. If you want to verify it yourself, that’s easy too. Take a 500-milliliter bottle and take a sample from its delivery slot. Let it sit for 8 hours to see how much clear water floats on top and how much residue is at the bottom. Simply weigh and calculate. It’s pretty much right.
