POM 韩国工程塑料 FU2025 高抗冲,增韧级,标准级

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 todistinguish co-polyformaldehyde and homopolyformaldehyde; POMplastics can be divided into copolymerization andhomopolymerization according to structure. Copolymerized POM hasexcellent thermal stability, processing performance and chemicalresistance, and is more widely used than homopolymer POM. Thedensity and mechanical properties of homopolymer are higher thanthose of copolymer POM, but the thermal stability is poor, theprocessing temperature is narrowed by about 10 ℃, and the stabilityto acid and alkali is low. POM copolymer has low melting point,thermal stability, chemical corrosion resistance, flowcharacteristics, hydrolysis resistance, strong alkali resistanceand thermal oxidation degradation, and its processability issuperior to homoformaldehyde. POM homopolymer has highercrystallinity, creep, lower thermal expansion, better wearresistance, mechanical strength, rigidity and thermal deformationtemperature than co-formaldehyde; The property of co-formaldehydeis formed by adding ethylene oxide polymer into the formaldehydehomopolymer Next, please compare the physical properties ofstandard grades of formaldehyde copolymer and homopolymer Althoughin terms of short-term mechanical properties, homopolymer tends tobe higher than copolymer, in terms of long-term mechanicalproperties, copolymer has a smaller proportion of reduction thanhomopolymer. Therefore, in terms of creep damage life and otheraspects, resin strength reversal will occur beyond a certain timepoint; Distribution of imported POM Korean engineering plasticsFU2025                                                                                                                                                                                                                                                             Какотличить полиформальдегид от гомополиформальдегида;  ПластикPOM можно разделить на сополимеризацию и гомополимеризацию поструктуре, термостабильность, производительность обработки ихимическая устойчивость сополимеризованного POM превосходны, иболее широкая, чем плоскость применения гомополимерного POM, аплотность гомополимеризации,
