Will the size of pc material become smaller if it is not dried

Yes. PC material belongs to plastic materialCan PC material be produced without drying?, there is shrinkageCan PC material be produced without drying?, if it is not dried before leaving the factory, the problem of size reduction will occur after leaving the factoryCan PC material be produced without drying?, will become smaller. Polycarbonates, also known as PC plastics, are high molecular polymers containing carbonate groups in their molecular chains. According to the structure of the ester groups, they can be divided into aliphatic, aromatic, aliphatic and aromatic types.

When making products with PC/ABS fiber adding materials, too fast the molding cycle will indeed lead to a smaller size of the finished product. This is a common process anomaly in injection molding.

Insufficient cooling time: The thermal deformation temperature of glass fiber reinforced materials is higher than that of pure PC/ABS. Shortening the cooling time will cause the parts to be ejected before they are completely cured. After being ejected, the parts will continue to shrink at room temperature, ultimately resulting in the overall size. Small. Specific impact scenarios: The thin-walled structure itself dissipates heat quickly, and the problem of insufficient cooling after shortening the cycle will be amplified, and the probability and magnitude of a small size will be higher.

The size becomes smaller because plastic has shrinkage, which shrinks after injection molding cools, so the size becomes smaller. The reason for the change in the size of PC/ABS injection molded parts is that the control system of the injection machine is unstable. The forming window is too narrow. Inappropriate forming conditions. The Check ring of the injection unit is damaged. The nature of plastic parts is unstable. The flow channel is unbalanced.

Secondly, the adhesive properties between wet PC steel rods and surrounding materials may deteriorate. For example, in concrete structures, it will affect the collaborative work effect between steel rods and concrete and reduce the overall performance of the structure. Moreover, the humid environment may affect the accuracy of PC steel rods during processing, making it difficult for them to reach the required size and shape, and affecting subsequent installation and use.

Reduced strength Moisture will destroy the interaction force between PC molecular chains, resulting in damage to the internal structural integrity of the material. This makes the material more likely to produce stress concentration when subjected to stress, and its ability to resist damage is significantly reduced. Change in toughness A small amount of water absorption may temporarily increase the toughness due to plasticization, but too much water absorption will cause the material to soften, and the impact resistance will decrease, which cannot meet the requirements of high-impact applications.

Do I need a dryer to process granules

1. Processing granules requires a dryer, depending on the granulesCan PC material be produced without drying?Raw material characteristics, production process and storage requirements. If a dryer is needed, the moisture content of high-moisture raw materials biomass particles (wood chips, straw, etc.) usually exceeds 30%, and a dryer must be used to reduce the moisture to 12%-15% before they can be formed. When processing grains (such as feed and pills) in the food and pharmaceutical industries with special materials, the water activity must be strictly controlled to prevent mildew, and a dryer must be used.

2. The basic equipment needed to process granular grains includes crushers, mixers, pelletizers and drying and cooling equipment. The total investment ranges from several thousand to tens of thousands of yuan depending on the scale. Core processing equipment Crushing equipmentCan PC material be produced without drying?: Hammer-type crushers are the most commonly used. The power of household miniature machines is 3-5kW and the output per hour is 100-300 kilograms (dry material).

3. The selection of dryers suitable for biological particle processing needs to be comprehensively decided based on the output scale, raw material characteristics and energy consumption needs. The following scenarios analyze the specific types and advantagesCan PC material be produced without drying?: Small batch production plan Box dryer: Easy to operate and suitable for small-scale processing. It can accurately control temperature and time to ensure uniform moisture content of biological particles.

4. Fermentation can be completed in 3-5 days. After fermentation, the material has no pungent smell, is dark brown in color and soft in texture.

What are the solutions for the PC material melting index to become high after injection molding

1. Optimization of raw material pretreatment (1) Strictly control the quality of raw materials and additives PC is a strong hygroscopic resinCan PC material be produced without drying?, must be dried until the moisture content is ≤0.02% before injection moldingCan PC material be produced without drying?, it is recommended to use a blower dryer, the drying temperature is set to 110~120℃, and the drying time is 3~4 hoursCan PC material be produced without drying?Avoid excessive drying causing adhesion of material particles, or insufficient drying causing high-temperature hydrolysis and degradation. Empty remaining raw materials in the hopper after shutdown for more than 8 hours.

2. Pretreatment of raw materials (1) Strictly drying and dehumidifying the water absorption rate of PC is as high as 0.15%-0.3%. Injection molding after water absorption will cause hydrolytic degradation. The moisture content of raw materials must be controlled within ≤0.02%. Use a hot air circulation dryer, set the drying temperature to 110-120℃, and the drying time to 4-6 hours. Large thick-walled products need to be extended to 8 hours. Materials need to be added immediately after drying is completed to prevent raw materials from absorbing moisture again in the workshop environment.

3. Solid state polycondensation chain repair This program is an industrial batch repairCan PC material be produced without drying?The mainstream method is suitable for melting recycled materials with a high degradation degree of more than 50% higher than that of brand new PC.Can PC material be produced without drying?:(1) Pre-treatment requires that the PC recycled material be broken into 5 - 10mm particles and dried by hot air at 120 ° C for 4 - 6 hours to ensure that the moisture content of the material is ≤0.02%, so as to avoid hydrolysis and degradation. Clean up residual impurities inside the equipment to prevent contamination of repair materials.
