style="text-indent:25px">簡介：縮醛樹脂是強(qiáng)而硬且有良好疲勞性和熱穩(wěn)定性的熱塑(性)塑料，它電具有低的摩擦系數(shù)和良好的耐熱性以認(rèn)為縮醛樹脂類似于尼龍，但它的耐疲勞性、耐蠕變性、硬度和耐水性比尼龍更好。但是縮醛樹脂的抗蠕變能力不如聚碳酸酯。如前所述，縮醛樹脂具有優(yōu)異的耐溶劑性，還沒有找到在70℃以下可以溶解縮醛樹脂的有機(jī)溶劑；但是它可以在某些溶劑中溶脹?？s醛樹脂對酸、堿和氧化劑敏感。盡管C—O鍵是極性的．但它已被平衡．且極性比尼龍中的羰基小得多，其結(jié)果導(dǎo)致縮醛樹脂具有相對低的吸濕性。吸附的少量濕氣可能引起溶脹和尺寸變化，但不會導(dǎo)致聚合物水解而降解。濕氣的影響比尼龍聚合物小得多。紫外線光町能會{f起聚合物降解，町以通過加入炭黑來降低這種降解。共聚物通常具有和均聚物類似的性質(zhì)，但均聚物的力學(xué)性能比共聚物稍高一些．其熔點也更高，但其熱穩(wěn)定性和耐堿性比共聚物差。均聚物和共聚物都是填充填料(玻璃纖維、含氟聚合物、芳族聚酰胺纖維和其他填料)制成增韌級、紫外線光(UV)穩(wěn)定級材料。縮醛樹脂與聚氨酯彈性體共混提高其韌性，這些材料都可以在市場上買到。蘇州食品級POM廠商聚甲醛全名聚甲醛樹脂，簡稱聚甲醛，熱塑性結(jié)晶聚合物。被譽(yù)為“超鋼”或者“賽鋼”。</p><div

style="text-indent:25px">聚甲醛pom有毒嗎：POM無毒，但是加工方法不當(dāng)就會產(chǎn)生毒氣。在加工時，POM會釋放一種刺激性難聞氣體，但對人體的危害是不大的，產(chǎn)品做出來后的POM制品（聚甲醛）常溫下裂解是相當(dāng)緩慢的但是如果在特殊條件下，比如說高溫，或者裂解催化劑存在的條件下會進(jìn)行的很快，聚甲醛（POM）在注塑生產(chǎn)過程中會有少量的甲醛氣體產(chǎn)生，在正常的生產(chǎn)條件下，不會產(chǎn)生嚴(yán)重的問題。但是聚甲醛在高溫220攝氏度下就會發(fā)生熱降解，尤其是在長時間處于高溫下時，容易產(chǎn)生大量的甲醛氣體。這種氣體是刺激性的，對眼部和咽喉都有傷害。吸入過多會有暈眩惡心感。POM熱分解時會揮發(fā)出有毒氣體，對人體產(chǎn)生危害。但是，這與加工成型工藝有很大關(guān)系。加工工藝好和工作環(huán)境好的工廠，是不會出現(xiàn)安全問題的，放心工作好了。</p><p style="text-indent:25px">聚甲醛可以進(jìn)行擠出成型、注射成型和二次加工成型。加工聚甲醛時應(yīng)注意： (1)固體狀的聚甲醛結(jié)晶度達(dá)75、80％，是一種高結(jié)晶性聚合物。 (2)熔點175℃，加工溫度200～205℃，凝固點160℃，用常溫水冷卻，使其結(jié)晶的凝固速度比熔融速快得多，因此在凝固點以下即成剛性(擠出時用短的冷卻水槽，注射時縮短冷卻時間就行)。 (3)容積的變化：設(shè)熔融時為l，則凝固時為0．89，常溫時為0．84。 (4)由于凝固速度快且容積變化大，故擠出物表面容易開裂、變形，冷卻時要特別注意。若使用較高溫度的冷卻劑則可放慢凝固速度，控制其牽引，使制品有良好的表面光潔度。 (5)避免在擠出機(jī)中作長時間的滯留：在230℃時，只允許留15分鐘，避免酸性、堿性異物混入，否則容易引起分解，因此對所用顏料必須嚴(yán)加挑選。聚甲醛其他原料更換為聚甲醛時，除了加工溫度比聚甲醛低的物料或相近的物料，必須用聚乙烯清洗過渡。</p><div style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">聚甲醛材料物理性質(zhì)：聚甲醛是高聚物，其結(jié)晶度相對較高，它的綜合力學(xué)性比起其它的塑料要好很多，比如它具有很高的強(qiáng)度、很高的硬度，其彈性模量更是比一般塑料大很多，它具有與金屬材料很接近的比強(qiáng)度和比剛度；聚甲醛材料的沖擊強(qiáng)度和疲勞強(qiáng)度相對較高、并擁有不錯的耐磨性。聚甲醛材料結(jié)構(gòu)：按其合成方法，聚甲醛樹脂有均聚甲醛和共聚甲醛兩種類型。均聚甲醛以均聚合成方法制成，共聚甲醛以共聚合成方法制成，它們的分子結(jié)構(gòu)雖然均為線性結(jié)構(gòu)，但略微的有所區(qū)別。由于分子結(jié)構(gòu)不同，所以性能不同。兩者材料相比，均聚甲醛的密度更大，熔點更高，強(qiáng)度更好，但熱穩(wěn)定性和耐酸堿能力要比共聚甲醛材料的差；初次之外共聚甲醛熱穩(wěn)定性要好很多，并且易于成型，因而共聚甲醛發(fā)展相對均聚甲醛發(fā)展的要快。日本寶理POMM90S</p><p
