An important role of glass fiber in Blow molding
Glass fiber reinforced plastic is on the basis of the original pure plastic, glass fiber and other additives, so as to improve the use range of the material.Generally speaking, most of the glass fiber reinforced material use on the structure of the product parts, is a kind of structural engineering materials;Such as: PP ABS PA66, PA6 PC POM PPO PET PBT, PPS.
Advantages:
1. After glass fiber reinforced, glass fiber is high temperature resistant material, therefore, reinforced plastic heat resistance than without the glass fiber used to improve a lot,especially the plastic nylon;
2. After Glass fiber reinforced, due to the addition of glass fiber, limit the move each other, between the plastic polymer chain, therefore, reinforced plastics shrinkage rate decreased a lot, also greatly improve the rigidity;
3. After glass fiber reinforced, reinforced plastic won't stress cracking, at the same time, the plastic shock resistance for improvement of the many.
4. After Glass fiber reinforced, glass fiber is high strength material, thus raised the strength of the plastic, such as tensile strength, compression strength, bending strength, improve a lot;
5. After Glass fiber reinforced, because of the addition of glass fiber and other additives, reinforced plastics combustion performance a lot, most of the material cannot fire, is a kind of flame retardant materials.
Disadvantages:
1. After glass fiber reinforced, due to the addition of glass fiber, transparent, before the glass fiber is will become opaque.
2. After Glass fiber reinforced, after all the toughness of the plastic is reduced, and the brittleness increases;
3. After glass fiber reinforced, due to the addition of glass fiber, all material melt viscosity increase, liquidity becomes poor, injection pressure to increase a lot than without glass fiber;
4. After Glass fiber reinforced, due to the addition of glass fiber, liquidity is poor, in order to normal blow molding, all of the reinforced plastic blow molding temperature than before without glass fiber increased 10-30 degrees;
5. After glass fiber reinforced, because of the addition of glass fiber and auxiliaries, moisture absorption properties of the reinforced plastic strengthen greatly, the original pure plastic non-absorbent will become water absorption, therefore, when blowing into the drying.
