style="text-indent:25px">聚甲醛(POM)可替代哪幾種工程塑料：1.替代聚碳酸酯汽車工業(yè)中PC在內(nèi)外裝飾件方面使用歷史比較悠久，但聚甲醛固有性能加上相關(guān)新技術(shù)帶來的可能性及成本差別，使之在內(nèi)外裝飾件范疇內(nèi)替代了一大批PC的結(jié)構(gòu)方案。 2.替代聚苯硫醚PPS雖體現(xiàn)出它對與其他通用工程塑料的總體優(yōu)勢，但實(shí)際的應(yīng)用領(lǐng)域中，綜合性能方面與聚甲醛的差距，以及聚甲醛本身的特長，使聚甲醛有很好的機(jī)會(huì)進(jìn)入通常為PPS所占據(jù)的應(yīng)用領(lǐng)域。 3.替代聚四氟乙烯：摩擦磨耗特性與耐疲勞、耐蠕變性，使得其在許多應(yīng)用中能夠取代聚四氟乙烯。聚甲醛之所以有前景極好以及能扮演多面角色這兩個(gè)好處，韓國工程POMFR-20H，就是它有過千頭萬緒的不同用法，有了太多的商業(yè)上可以得到的現(xiàn)成的品級選擇范圍，色的摩擦磨耗特性加上出色的剛性抗蠕變及抵御烴類的能力，市場上的地位可用強(qiáng)勁二字來描述。聚甲醛除了強(qiáng)酸，韓國工程POMFR-20H，韓國工程POMFR-20H、酚類和有機(jī)鹵化物外，對其他化學(xué)品穩(wěn)定，耐油；機(jī)械性能受溫度影響小。韓國工程POMFR-20H</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="韓國工程POMFR-20H,POM" src="https://tyunfile.71360.com/UploadFile/szjingsumi/637387288132771805/7721743.png"></div><p style="text-indent:25px">基本性能：POM分為兩大類，一類為均聚甲醛，以杜邦和旭化成為表示，另一類為共聚甲醛，除了上述兩家，其他供應(yīng)商的產(chǎn)品基本都為共聚，旭化成是個(gè)NB的公司，均聚和共聚都生產(chǎn)。這里簡單介紹一下均聚和共聚的特點(diǎn)，以便更準(zhǔn)確的選擇材料。耐熱性能：耐熱性能≠熔點(diǎn)，而是POM長期在高溫環(huán)境下工作的能力。由于均聚甲醛分子鏈中基本都是-C-O-鍵，鍵能大約為20~40 kcal/mol，而共聚甲醛中增加了一些-C-C-O-鍵，鍵能大約是60~80 kcal/mol，因此需要共聚甲醛分解所需的能量更高，so，共聚甲醛的長期熱穩(wěn)定性更好。熱穩(wěn)定性能影響的不僅是產(chǎn)品的工作環(huán)境，同時(shí)對于現(xiàn)在汽車產(chǎn)業(yè)的VOC及氣味管控也有著很大的影響，均聚甲醛注塑的時(shí)候氣味大，而對于POM而言，氣味一般就表示甲醛釋放量大，這酸爽，聞過的都知道。蘇州煤制POM公司聚甲醛流動(dòng)性中等，溢出值為0.04mm。流動(dòng)性對溫度變化不敏感，但對注射壓力的變化敏感。</p><div

100°C溫度范圍內(nèi)長期使用。它的耐磨性和自潤滑性也比絕大多數(shù)工程塑料優(yōu)越，又有良好的耐油，耐過氧化物性能。很不耐酸，不耐強(qiáng)堿和不耐月光紫外線的輻射。聚甲醛的拉伸強(qiáng)度達(dá)70MPa，吸水性小，尺寸穩(wěn)定，有光澤，這些性能都比尼龍好，聚甲醛為高度結(jié)晶的樹脂，在熱塑性樹脂中是zui堅(jiān)韌的。具抗熱強(qiáng)度，彎曲強(qiáng)度，耐疲勞性強(qiáng)度均高，耐磨性和電性能優(yōu)良。提高聚甲醛的耐候性：在聚甲醛中加入抗氧劑及光穩(wěn)定劑可以提高聚甲醛的耐候性。針對POM受紫外線照射易發(fā)生白化、龜裂等缺點(diǎn)，一些科研機(jī)構(gòu)紛紛開發(fā)出耐候型品種，以滿足汽車內(nèi)外裝飾材料的要求。導(dǎo)電、抗靜電聚甲醛：采用加入炭黑、碳纖維、不銹鋼纖維等導(dǎo)電填充料的方法，可以提高聚甲醛導(dǎo)電性能。在聚甲醛中加入特殊的抗靜電劑則可使聚甲醛具有抗靜電性，減少其在電子領(lǐng)域應(yīng)用時(shí)因灰塵、碎屑積聚及靜電荷產(chǎn)生的干擾。聚甲醛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。杭州透明POM廠家推薦</p><p
