What causes the deformation of chemical plastic barrels when used

- Oct 16, 2020-

Transparent chemical plastic barrels must first have high transparency, and secondly they must have certain strength and abrasion resistance, impact resistance, heat-resistant parts, chemical resistance, and water absorption. Only in this way can they be used and can be It meets the requirements of transparency and remains unchanged for a long time. In addition, this kind of chemical plastic barrels will encounter common problems during use. Because of the high light transmittance of transparent plastics, the surface quality of plastic products must be strict, and there should be no markings. , Stomata, whitening. Haze, black spots, discoloration, poor gloss and other defects, so the raw materials and equipment in the entire injection molding process. The design of molds and even products must pay great attention to and put forward strict and even special requirements. Transparent chemical plastic barrels must first have high transparency, and secondly they must have certain strength and abrasion resistance, impact resistance, heat-resistant parts, chemical resistance, and water absorption. Only in this way can they be used and can be To meet the requirements of transparency and remain unchanged for a long time, the following table lists the performance of pmma, pc and pet. Due to the variety of varieties, this is just an average value. Actual data for different varieties are different. The pet data (mechanical aspect) is the data after stretching. ...

In the process of use, this kind of chemical plastic barrels will also encounter common problems. Because of the high light transmittance of transparent plastics, the surface quality of plastic products must be strict, without any markings, pores, and whitening. Haze, black spots, discoloration, poor gloss and other defects, so the raw materials and equipment in the entire injection molding process. The design of molds and even products must pay great attention to and put forward strict and even special requirements. Secondly, because transparent plastics mostly have high melting point and poor fluidity, in order to ensure the surface quality of the product, it is often necessary to make fine adjustments in the high temperature, injection pressure, injection speed and other process parameters of the machine, so that the mold can be filled with the plastic during injection. Will produce internal stress and cause product deformation and cracking.

The production of each product has its own application. For the chemical plastic barrels we are talking about today, it is no exception. Its application can be used to install liquids that will produce chemical reactions. At this time, we should do it first. Take precautions to confirm its response and whether it can withstand its temperature. Chemical plastic barrels can usually be installed with liquids. At room temperature, there is no problem with salt, alkali, and other mixtures. Chemical plastic barrels cannot be used to install strong oxidizing liquids, such as sulfuric acid whose temperature is higher than 60 degrees, sulfuric acid whose concentration is higher than 75%, and concentrated nitric acid whose concentration is higher than 30%. In addition, for the production of chemical plastic barrels, it can also be used for the storage and transportation of various liquids. It has good characteristics for special dangerous goods packaging. It has the characteristics of not fragile, rustless, light weight, and is resistant to oil and strong. It has good corrosion performance and is mostly used for packaging of dangerous goods that require heat preservation, moisture resistance, pressure resistance and corrosion resistance. It is precisely because of its wide range of applications that it has such a good development prospect.https://www.fhpails.com/
