多数塑料很自然地在根部滑动,因为它们进入时是冷的,摩擦力还没有把根部加热到和筒壁一样热。一些材料比另一些材料更可能粘附:高度塑化PVC,非晶体PET,和 某些终使用中想要的有粘附特性的聚烯烃类共聚合物。
带槽筒体是一种特殊情况。槽在进料区,进料区与筒体其余部分是热绝缘的并是深度水冷的。螺纹把颗粒推入槽内并在一个相当短的距离内形成一个很高的压力。这增加了相同输出较低螺杆转速的咬合允量,从而前端产生的摩擦热量减少,熔体温度更低。这可能意味着冷却限制吹制膜生产线中更快的生产。槽特别适合于HDPE,它是除过氟化塑料之外滑的普通塑料。

PC树脂的可见光透过率在90﹪以上，具有突出的抗冲击能力，耐蠕变，尺寸稳定性好及耐化学腐蚀性，耐热、吸水率低、无毒、介电性能优良，还有自熄、易增强阻燃性等优良性能。PC是几乎无色的玻璃态的无定形聚合物，有很好的光学性。PC高分子量树脂有很高的韧性，悬臂梁缺口冲击强度为600~900J/m，未填充牌号的热变形温度大约为130°C ，玻璃纤维增强后可使这个数值增加10°C。PC的弯曲模量可达2400MPa以上，树脂可加工制成大的刚性制品。低于100°C 时，在负载下的蠕变率很低。PC耐水解性差，不能用于重复经受高压蒸汽的制品。PC主要性能缺陷是耐水解稳定性不够高，对缺口敏感，耐有机化学品性，耐刮痕性较差，长期暴露于紫外线中会发黄。和其他树脂一样，PC容易受某些有机溶剂的浸浊。PC材料具有阻燃性，耐磨。抗氧化性。PC由于具有优异的综合性能，尤其以耐冲击强度高而被誉为塑料之“冠”，是使用范围十分广泛、性能优异、备受欢迎的主要热塑性工程塑料品种之一。 PCCostco (Bayer) rx1805451118pc/PC 518R/m. Holland usage: otherimportant parameters: melt flow rate: 15G/10min density: 1.2 g/cm3notch impact strength: 854 tensile strength: 60mpa elongation atbreak: 150% bending modulus: 2,410 MPa hardness: 68 hot deformationtemperature: 127 ° C something most plastics slide naturally at theroot, because they come in cold, and the friction hasn't yet heatedthe roots to the same heat as the barrel wall. Some materials aremore likely to adhere than others: highly plasticized PVC,amorphous PET, and certain end-use polyolefin copolymers withdesired adhesion properties. The grooved cylinder is a specialcase. The trough is in the feed area, which is thermally insulatedand deeply water-cooled from the rest of the cylinder. The threadpushes the particles into the groove and creates a high pressureover a fairly short distance. This increases the occlusionallowance for the same output at lower screw speeds, resulting inless friction heat at the front end and lower melt temperatures.This may mean that cooling limits faster production in blown filmproduction lines. The tank is particularly suitable for HDPE, whichis a general purpose plastic that slides in addition toperfluorinated plastics. Medical devices; high anti-lipid property;suitable for high energy radiation sterilization; Biocompatibilitymeeting many ISO 10993-1 test requirements; high viscosity;injection molding-melting temperature 280-320 â ° C; transparentcomponents of medical devicesThevisible light transmittance of PC resin is over 90% , it hasoutstanding impact resistance, creep resistance, good dimensionalstability and chemical corrosion resistance, low heat resistance,low water absorption, non-toxic and excellent dielectricproperties, there are self-extinguishing, easy to enhance flameretardancy and other excellent properties. PC is a nearly colorlessamorphous glassy polymer with excellent optical properties. PC highmolecular weight resin has high toughness. The notched impactstrength of the cantilever beam is 600 ~ 900 J/m. the hotdeformation temperature of the unfilled grade is about 130 ° C,which can be increased by 10 ° C when the glass fiber isreinforced. The bending modulus of PC can reach more than 2400MPa,and the resin can be processed into large rigid products. The creeprate under load is very low below 100 ° C. PC has poor hydrolysisresistance and can not be used for products subjected to repeatedhigh pressure steam. The main performance defects of PC are lowhydrolysis stability, notch sensitivity, resistance to organicchemicals, poor scratch resistance and yellowing after long-termexposure to UV light. Like other resins, pcs are susceptible toclouding by certain organic solvents. PC material hasflame-retardant, wear-resistant. Antioxidant. PC is known asthe“Crown” of plastics because of its excellent comprehensiveproperties, especially its high impact strength, it is one of themost popular thermoplastic engineering plastics with wideapplication and excellentperformance.
