I often encounter purchasing girls or agent brothers who do not understand technology. They immediately send a list of metallographic sandpaper and honestly and lovingly say:; Do you have these things at home? Give me a quote&# quo;!

    Do you see it? That's a list like this. At first glance, you may not really see anything wrong, after all, there are basic elements, product name: sandpaper; P240, P1000, P2500, P4000, these are the particle sizes of sandpaper, and there is no problem; Product category: AS0309, which is user-defined and has no relation to the product information provided by the merchant; Product Description: Laboratory consumables, no issues; Do you have accurate data on both quantity and unit? Is it possible to make a purchase with such a purchase list in front of you? Answer: No!


Because, as a consumable material for metallographic laboratories, metallographic sandpaper has many specifications and models, no less than dozens, and can be divided into circular, rectangular, and strip (strip) shaped shapes. From the particle size, it can be divided into coarse to fine P60-P4000. In general, there are many types of circular metallographic sandpaper purchased, with diameters ranging from 3 inches, 8 inches, 10 inches, and 12 inches. The diameter of the metallographic sandpaper is mainly determined based on the diameter of the grinding disc of the metallographic polishing machine, and matched for use. In addition, circular metallographic sandpaper can be divided into two types: with adhesive and without adhesive. The one with adhesive can be directly pasted on the grinding disc, making it more convenient to use; Without adhesive backing, it needs to be fixed on the grinding disc using sandpaper clamps. For rectangular metallographic sandpaper, it is generally used for manual rough grinding or pre grinding, and generally does not require backing adhesive. The sand belt (long strip shape) is mainly used for metallographic sand belt pre grinding, and requires technical parameters of length and width as the purchasing basis. The above technical parameters may seem quite complex, but in fact, in summary, only three parameters are provided to the seller, which can help you choose metallographic sandpaper that meets the technical requirements. What about the three parameters?

    Compare these two lists to see the difference? Yes! That's it. The list on the bottom image has an additional section in red compared to the list on the top. Now we have revealed three main parameters: size specifications, whether there is adhesive backing, and what is the particle size. Once these three parameters are determined, the specifications and models of the metallographic sandpaper are determined. As for which brand, packaging specifications and quantity you need to choose, technical parameters that meet the preparation requirements of metallographic samples are essential for purchasing young girls and brothers. Price and other factors depend on the brand, quantity, payment method, and many other factors purchased. By negotiating and reaching an agreement with the supplier based on your own unit's actual situation, you can form a purchase intention, sign a purchase order, and so on. We won't go into detail here.

    Have you understood the above introduction to the selection methods for metallographic sandpaper for newly started purchasing girls and brothers? The important thing to repeat is that each time you inquire about a supplier, you only need to provide three parameters: size specifications, whether it comes with adhesive backing, and what is the particle size. The supplier will immediately select the model and provide you with a quotation, without any errors, nor will you have to go back and forth with metallographic engineers or users to confirm these parameters, saving valuable time and unnecessary trouble. Remember, before purchasing metallographic sandpaper for inquiry, be sure to confirm these three technical parameters with your users, and then you can easily inquire and purchase.
