Application fields of polycarbonate (PC) raw materials (Part 2)

1. Construction fieldCan PC make water top molds?: PC has good light transmission, impact resistance and weather resistanceCan PC make water top molds?, can be used to make lighting roofs, sound insulation barriers, decorative panels, etc. The lighting roof allows natural light to fully enter the roomCan PC make water top molds?, reduce the use of artificial lighting and reduce energy consumption; sound insulation barriers can effectively reduce the impact of traffic, industrial and other noise on the surrounding environment; decorative panels provide for building exterior and interior decorationCan PC make water top molds?Diversified options.

2. The four major modification application directions of polycarbonate (PC) are as follows: Toughened PC Toughened PC is divided into ordinary grade Toughened PC and high-flow Toughened PC: Ordinary grade Toughened PC: It has good impact resistance and impact properties. Adjustable, small molding shrinkage, good size stability, good weather resistance, high low-temperature impact performance, and can be sprayed. It is mainly used in electronic and electrical products such as thin-walled products, auto parts, and mobile phones, such as mobile phone casings.

3. Polycarbonate (PC) is a widely used engineering plastic. Its excellent transparency and impact resistance make it play an important role in many fields. The main application areas of PC include glass assembly, automotive industry and electronics.

Chemical properties of PC materials, matters needing attention in mold forming

Avoid injecting glue by point or diving glue (PC is commonly known as bulletproof glass glue, and poor fluidity can easily lead to defects).

Performance characteristics Thermal stability and forming characteristics: PC flame retardant material is amorphous material with good thermal stability and a wide forming temperature range, but poor flowability. It is hygroscopic and sensitive to water and must be dried before forming. Forming shrinkage is small, but melt fracture and stress concentration are prone to occur. Therefore, forming conditions need to be strictly controlled, and the plastic parts after forming must be annealed.

PC material is an amorphous plastic with excellent thermal stability, a wide molding temperature range and poor flowability. It has little moisture absorption but is sensitive to moisture, so it needs to be dried. During the forming process, PC materials have small shrinkage, but are prone to melt cracking and stress concentration. Therefore, it is necessary to strictly control the forming conditions and anneal the plastic parts to eliminate internal stress.

Processing precautions: hygroscopicity: PC materials have strong hygroscopicity, so it is necessary to ensure that the materials are completely dried before processing to avoid problems during processing. The recommended drying conditions are 100 ° C to 200 ° C for 3 to 4 hours, and the humidity before drying must be less than 0.02%. Injection molding temperature: During the injection molding process, the melting temperature should be controlled between 260 and 340℃, and the mold temperature should be maintained between 70 and 120℃.

What is the production process of PC plastic barrels for bottled water?

1. Bottled water PC plastic barrelCan PC make water top molds?The core of production is through the injection molding processCan PC make water top molds?In conjunction with strict raw material control and post-processing processes, containers that meet food contact safety standards are finally obtained. Preparation and pretreatment of raw materials-Select food-grade PC granules that comply with GB 4807-2016 "National Food Safety Standards for Plastic Materials and Products for Food Contact". The raw materials must be dried at 80 - 100 ° C for 4 - 6 hours in advance to remove moisture to avoid defects such as bubbles and flow marks during injection molding.

2. Barrel buckets for water dispensers are generally made through 7 standard processes and are prepared. Food grade polycarbonate (PC) plastic particles are usually used as raw materials. This material has high transparency, strong toughness, high and low temperature resistance, and is in line with drinking water packaging. According to the health and safety standards, the particles are added to the hopper of the injection molding machine to complete the preliminary preparation.

3. The mainstream water bucket on the water dispenser is made using blow molding process to complete the entire production process. It is divided into 7 steps from raw material preparation to finished product deliveryCan PC make water top molds?: Preparation of raw materials: Food grade polycarbonate (PC) particles are mainly used. This material has high transparency, good strength, impact resistance, hygiene and safety, and fully meets the safety standards for drinking water packaging.

4. The bucket on the water dispenser is mainly made by a series of processes such as clamping a plastic pipe to a mold and rinsing it through a machine under high pressure. The following is the detailed production process: Raw materials The raw materials used to prepare water dispenser buckets are usually polycarbonate (PC) plastic particles. PC plastic has the advantages of high transparency, good impact resistance, and strong heat resistance. It is very suitable for making water dispenser buckets that need to withstand a certain amount of pressure and ensure safe water quality.
