What is the expulsion temperature of fire resistant PC plastic? Could it at any point be infusion shaped?

Explicit gravity of fire resistant PC: 1.18-1.20 g/cubic centimeter shaping shrinkage: 0.5-0.8% trim temperature: 230-320 ℃ drying conditions: 110-120 ℃ for 8 hours, it tends to be utilized for quite a while under – 60~120 ℃. The material has high effect strength, great layered solidness, dreary and straightforward, great shading, great electrical protection, erosion opposition and wear obstruction, however it has unfortunate self oil, stress breaking propensity, simple hydrolysis at high temperature, and unfortunate similarity with different tars. Appropriate for making little instrument parts, protecting straightforward parts and effect safe parts.

Execution of PC plastic unrefined components at expulsion temperature:

1. Shapeless material, great warm steadiness, wide embellishment temperature reach and unfortunate ease. Dampness assimilation is little, however it is delicate to water and should be dried. The trim shrinkage is little, which is inclined to dissolving breaking and stress focus. Accordingly, the embellishment conditions ought to be completely controlled, and the plastic parts should be tempered.

2. Warmed expansion spout ought to be utilized for plastic parts with high liquefying temperature and high thickness, which are more prominent than 200g.

3. The cooling speed is quick, and the shape pouring framework depends on the standard of thick and short. It is proper to set a virus charging great, the entryway ought to be bigger, and the form ought to be warmed.

4. In the event that the material temperature is excessively low, it will cause material deficiency, plastic parts are Matt, and assuming the material temperature is excessively high, it is not difficult to spill over and plastic parts rankle. At the point when the shape temperature is low, the shrinkage, stretching and effect strength are high, and the twisting, pressure and rigidity are low. At the point when the form temperature surpasses 120 ℃, the plastic part cools gradually and is not difficult to distort and adhere to the shape.

Process qualities

1. The ease of the arrangement is delicate to temperature and uncaring toward pressure. It is near Newtonian liquid and has a place with consistency temperature delicate sort.

2. It very well may be viewed as an undefined polymer, with no conspicuous liquefying point, high dissolve consistency and troublesome stream. It is expected that the shape sprinter entryway is short and thick to diminish pressure misfortune, and simultaneously, higher infusion pressure is required.

3. Under high temperature, the gum is not difficult to hydrolyze, and silver wires are delivered on the items. The gum ought to be dried prior to handling, with the goal that the water content is underneath 0.02%. During the handling system, consideration ought to be paid to the protection of the pitch to keep the tar from retaining dampness once more.

4. The items are not difficult to break, so focus on dispense with the inward pressure of the items during handling, like expanding the shape temperature and post-treatment of the items.

Process qualities II

1. The embellishment shrinkage of the item is 0.5-0.7%, and the stream course is fundamentally steady with the upward heading.

The ease of the arrangement is connected with the wall thickness of the item. The stream length proportion of PC arrangement is 80-100:1, and the thickness of the item is by and large at the very least 1mm, generally between 1.5-5mm;

2. For items with wall thickness under 3mm and stream length under 250mm, it is permitted to take right on track door measurement of 0.8-1mm;

3. To assist with smoothing mold filling, the form temperature can be chosen between 120-0 ℃;

2、 Prerequisites for framing hardware

1. Hardware limit: it is expected that the infusion volume of items will not surpass 60-70% of the ostensible volume of the infusion shaping machine

2. Screw: the length measurement proportion l/d of the screw is 15-20, and the pressure proportion is 2-3.

3. Temperature control instrument: the temperature control instrument is expected to be openly changed between 400 ℃ – 0 ℃.

4. Spout: because of the unfortunate ease of PC, the spout opening measurement is 3-6mm, the opening length is 12-25mm, and is furnished with a different warming gadget.
