POM 美国杜邦 111PA NC010
POM塑料吸水性小,一般为0.2%-0.5%。在通常情况下,POM不需干燥就能加工,但对潮湿原料必须进行干燥。
干燥温度80℃以上,时间2小时以上,具体应按供应商资料进行。
再生料使用比例一般不超过20-30%。但要视产品的种类和最终用途而定,有时可达100%。
(PS:加工的时候为保证产品质量,建议最好做干燥处理,能提高材料的质量)
2、塑机的选用
POM除了要求螺杆无滞料区外,对注塑机没有特别要求,一般注塑即可。
3、模具及浇口设计
常见模具温度控制为80-90℃,流道直径有3-6mm,浇口长度为0.5mm,浇口大小要视胶壁厚度而定,圆形浇口直径至少应制品厚度的0.5-0.6倍,长方形浇口的宽度通常是厚度的2倍或以上,深度为壁厚的0.6倍,脱模斜度40′-1°30′之间。
排气系统
POM-H
厚度0.01-0.02mm
宽3mm
POM-K
厚度0.04mm 宽3mm
4、 熔胶温度
可用空射法量度
POM-H
可设为215℃ (190℃-230℃)
POM-K
可设为205℃ (190℃-210℃)
注塑影响条件
料筒温度:
因为聚甲醛(POM塑胶原料)是结晶性塑料,熔料在料筒内停留时间对于它的含晶核数量与大小均会产生影响,在其熔点以上的同一温度下,熔体停留时间越长,晶核数会下降。料筒温度通常应控制在150~180℃,温度不宜过高,太高会导致变色分解,过低则会塑化不均,影响流动性。所以在确保流动性的前提下,尽量采用较低的加工温度和较短的受热时间。另外喷嘴温度应略低于料筒温度。
模具温度:
通常模具是影响聚甲醛(POM)强度的主要因素,模温高,结晶时间长,有利于晶体的生长,结晶较完整,并且流动性会更好。一般情况下,模温应控制在75~120℃。
注射压力:
注射压力的大小主要取决于聚甲醛(POM)的熔融流动性,流道、浇口的厚度和宽度,以及塑料制品的厚度等因素。通常为40~130Mpa,对于厚壁制品,注射压力可取小值,反之薄壁制品则应取大值。
注射速度
常见为中速偏快,过慢易产生波纹,过快易产生射纹和剪切过热。
背压
越低越好,一般不超过200bar
滞留时间
如设备没有熔胶滞留点
POM-H
可在215℃滞留35分钟
POM-K
可在205℃滞留20分钟不会有严重的分解
在注塑温度下熔体不能在机筒内滞留超过20分钟。POM-K在240℃下可滞留7分钟。如果停机,机筒温度可降到150℃,如要长期停机就必须清理机筒子,关闭加热器。
停机
清理机筒必须用PE或PP,关闭电热,把螺杆推在前位。料筒和螺杆必须保持清洁。杂质或污垢会改变POM的过热稳定性(尤其是POM-H)。
所以当用完含卤聚合物或其他酸性聚合物后,应用PE清理干净后才能打POM塑胶原料,否则会发生爆炸。若作用不当的颜料、润滑剂或含GF尼龙的物料,会导致塑料降质。
后处理
对于非常温使用的制件且质量要求较高,须进行热处理。
退火处理效果,可将制品放入浓度为30%的盐酸溶液中浸30分钟检查,然后用肉眼观察判断是否有残余应力的裂纹产生。
POM 美国杜邦 111PA NC010
POM has been used in a number of other
engineering plastics, such as alternative zinc, brass, aluminum and steel, at a
cost that is lower than the cost of many other engineering plastics. Since its
inception, pom has been widely used Electrical and electronic, machinery,
instrumentation, daily light industry, automotive, building materials,
agriculture and other fields. In many new areas of application, such as medical
technology, sports equipment, etc., POM also showed a good growth trend.
1, the application of consumption
continued to grow
POM is particularly suitable for use in
industrial machinery, automobiles, electrical and electronic, pipe fittings and
irrigation products for use in slippery and rolling mechanical parts where
lubricity, abrasion resistance, rigidity and dimensional stability are
relatively stringent. etc. China pom market growth is rapid, in 2002 China pom
market apparent consumption of 13.657 million tons, 1990 ~ 2002 pom market
apparent consumption average annual growth rate of 11.7%. Expected in 2005
China pom market apparent consumption of 168,000 tons, 2000 to 2005 pom market
apparent consumption annual growth rate will reach 10.3%. By 2010, China pom
market apparent consumption will increase to 19.7 million tons, 2005 ~ 2010 pom
market apparent consumption of the average annual growth rate will reach 3.2%.
2, the technical gap can not be ignored
Although China's pom market demand
continues to rise, but because of China's relatively low research and
development of pom, China's pom production scale, production and variety,
quality has not been able to meet the needs of the market. China pom production
and other countries compared to the advanced level, there are still raw
material consumption, the device size is small, the quality of instability,
fewer grades and other issues.
3, lack of capacity growth needs
China pom industry for many years the
production capacity and production are low, production capacity and production
still can not meet the needs of the market. 2002 China pom manufacturers only
three, of which only Yuntianhua Group pom production equipment for the
10,000-ton (now expanded to 20,000 tons / year). 2002 China pom production
capacity of 12,800 tons / year, the output is about 10,000 tons. 1966 ~ 2002 China
pom production capacity of the average annual growth rate of 16.7%, the average
annual growth rate of 18.8%, showing that the expansion of domestic production
capacity of pom manufacturers is imperative. Is expected in 2005 China pom
manufacturers will reach 6, the total production capacity will reach 130,000
tons / year; (unreasonable, proposed to delete) is expected in 2010 China pom
production capacity of 190,000 tons / year, 2005 ~ 2010 pom production The
average annual growth rate of capacity will reach 7.9%.
Pom production in China pom production
capacity can not meet the needs of the reasons: the other countries pom market
growth faster, and China pom production base is relatively weak; another pom is
a capital and technology-intensive materials chemical products, China's huge
market caused The foreign countries have been trying to occupy the Chinese
market, do not want to transfer technology, so that China's pom technical level
to improve slowly, can not meet the needs of users; then there is a long time,
China's economic system and business mechanism is not In line with the laws of
the market economy, enterprises can not get enough capital investment in time,
restricting the development of pom production.
