怎么区分共聚聚甲醛与均聚聚甲醛； POM塑料按结构可以分为共聚和均聚，共聚POM 的热稳定性、加工性能及耐化学稳定性优良，且比均聚POM应用面广，而均聚的密度、力学性能结晶度高于共聚POM,但热稳定性较差，加工温度缩窄10℃左右，且对酸碱稳定性较低。
POM共聚物熔点低、热稳定性、耐化学腐蚀性、流动特性、耐水解、耐强碱和热力氧化降级、加工性优于均聚甲醛。
POM均聚物结晶度高、搞蠕变性、热膨胀率更低、耐磨性、机械强度、刚性、热变形温度等比共聚甲醛好；共聚甲醛的性质是在甲醛均聚物中加入氧化乙烯聚合物而共同形成的. 下面,请对甲醛共聚物与均聚物标准品级的物性进行一下比较. 虽然在短期机械特性方面,有均聚物高于共聚物的倾向,但在长期机械特性方面,共聚物则比均聚物降低的比例小.所以在蠕动破坏寿命等方面,越过某个时间点树脂就会发生强度逆转现象；进口POM韩国工程塑料FU2025经销 How to distinguish co-polyformaldehyde and homopolyformaldehyde; POM plastics can be divided into copolymerization and homopolymerization according to structure. Copolymerized POM has excellent thermal stability, processing performance and chemical resistance, and is more widely used than homopolymer POM. The density and mechanical properties of homopolymer are higher than those of copolymer POM, but the thermal stability is poor, the processing temperature is narrowed by about 10 ℃, and the stability to acid and alkali is low. POM copolymer has low melting point, thermal stability, chemical corrosion resistance, flow characteristics, hydrolysis resistance, strong alkali resistance and thermal oxidation degradation, and its processability is superior to homoformaldehyde. POM homopolymer has higher crystallinity, creep, lower thermal expansion, better wear resistance, mechanical strength, rigidity and thermal deformation temperature than co-formaldehyde; The property of co-formaldehyde is formed by adding ethylene oxide polymer into the formaldehyde homopolymer Next, please compare the physical properties of standard grades of formaldehyde copolymer and homopolymer Although in terms of short-term mechanical properties, homopolymer tends to be higher than copolymer, in terms of long-term mechanical properties, copolymer has a smaller proportion of reduction than homopolymer. Therefore, in terms of creep damage life and other aspects, resin strength reversal will occur beyond a certain time point; Distribution of imported POM Korean engineering plastics FU2025 Как отличить полиформальдегид от гомополиформальдегида; Пластик POM можно разделить на сополимеризацию и гомополимеризацию по структуре, термостабильность, производительность обработки и химическая устойчивость сополимеризованного POM превосходны, и более широкая, чем плоскость применения гомополимерного POM, а плотность гомополимеризации,
