POM吸水性小，一般為0.2%-0.5%。在通常情況下，POM不需干燥就能加工，但對(duì)潮濕原料必須進(jìn)行干燥。干燥溫度80℃以上，時(shí)間2小時(shí)以上，具體應(yīng)按供應(yīng)商資料進(jìn)行。 2.回用料：再生料使用比例一般不超過(guò)20-30%。但要視產(chǎn)品的種類和zui終用途而定，蘇州POM供應(yīng)商，有時(shí)可達(dá)99%。 3.塑機(jī)的選用： POM是結(jié)晶料，zui好用結(jié)晶料專業(yè)螺桿或尼龍PA螺桿，但POM的加工范圍寬泛，用一般注塑機(jī)也可以。 4.模具及澆口設(shè)計(jì)：常見(jiàn)模具溫度控制為80-90℃，流道直徑有3-6mm，澆口長(zhǎng)度為0.5mm，澆口大小要視膠壁厚度而定，圓形澆口直徑至少應(yīng)制品厚度的0.5-0，蘇州POM供應(yīng)商.6倍，蘇州POM供應(yīng)商，長(zhǎng)方形澆口的寬度通常是厚度的2倍或以上，深度為壁厚的0.6倍，脫模斜度40′-1°30′之間。聚甲醛繼聚酰胺之后又一種綜合性能優(yōu)良的工程塑料，具有高的力學(xué)性能。蘇州POM供應(yīng)商</p><div

style="text-indent:25px">聚甲醛材料熱性及化學(xué)性能：聚甲醛材料變形需要達(dá)到較高的溫度，并且它zui高允許連續(xù)使用的溫度為100°C左右。，聚甲醛材料的熱穩(wěn)定性相對(duì)來(lái)講是很差的，它在加熱時(shí)受其溫度的影響容易分解，并且在遇到光、氧的條件下還會(huì)發(fā)生老化的現(xiàn)象。能使聚甲醛材料熔融的溫度范圍比較小，一旦熔融，它的速度會(huì)很快并且凝固也很快和，其制品在澆注時(shí)容易產(chǎn)生毛斑、折皺等一般材料會(huì)出現(xiàn)的表面缺陷，所以在成型時(shí)要在設(shè)備參數(shù)和模具溫度控制方面采取嚴(yán)格的控制才能避免。聚甲醛容易溶于有機(jī)溶劑，它能耐稀酸，但不能耐強(qiáng)酸。南京多POM批發(fā)廠家聚甲醛結(jié)晶度高，機(jī)械強(qiáng)度、剛性、熱變形溫度等比共聚甲醛好。</p><div

style="text-indent:25px">聚甲醛抗靜電、絕緣改性：聚甲醛絕緣性能特別好，這使得聚甲醛容易產(chǎn)生靜電，從而限制了聚甲醛在石油化工廠及粉塵環(huán)境中的使用。通過(guò)添加一定比例的聚乙二醇可使聚甲醛具有永遠(yuǎn)的抗靜電效果。此外，可以通過(guò)添加碳納米管、炭黑等常用導(dǎo)電材料以提高聚甲醛的導(dǎo)電性質(zhì)。聚甲醛抗老化、光穩(wěn)定性改性：聚甲醛對(duì)紫外線非常敏感，在強(qiáng)烈的陽(yáng)光暴曬下，表面會(huì)變得粗糙。使用受阻胺622、292或苯并三唑類紫外線吸收劑UV—P對(duì)聚甲醛進(jìn)行紫外光保護(hù)，也可用炭黑進(jìn)行改性。</p><p style="text-indent:25px">用途：聚甲醛（POM）是一種性能優(yōu)良的工程塑料，在國(guó)外有“奪鋼”、“超鋼”之稱。POM具有類似金屬的硬度、強(qiáng)度和鋼性，在很寬的溫度和濕度范圍內(nèi)都具有很好的自潤(rùn)滑性、良好的耐疲勞性，并富于彈性，此外它還有較好的耐化學(xué)品性。POM以低于其他許多工程塑料的成本，正在替代一些傳統(tǒng)上被金屬所占領(lǐng)的市場(chǎng)，如替代鋅、黃銅、鋁和鋼制作許多部件，自問(wèn)世以來(lái)，POM已經(jīng)普遍應(yīng)用于電子電氣、機(jī)械、儀表、日用輕工、汽車、建材、農(nóng)業(yè)等領(lǐng)域。在很多新領(lǐng)域的應(yīng)用，如醫(yī)療技術(shù)、運(yùn)動(dòng)器械等方面，POM也表現(xiàn)出較好的增長(zhǎng)態(tài)勢(shì)。聚甲醛有較高的粘彈性，電絕緣性優(yōu)，且不受溫度影響；耐絕緣性好且不受濕度影響。</p><div

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(lái)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(duì)與其他通用工程塑料的總體優(yōu)勢(shì)，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(zhǎng)，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，就是它有過(guò)千頭萬(wàn)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(jí)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(chǎng)上的地位可用強(qiáng)勁二字來(lái)描述。聚甲醛具有較高的熱變形溫度。缺點(diǎn)是阻燃性較差，遇火徐徐燃燒，氧指數(shù)小。蘇州POM供應(yīng)商</p><p style="text-indent:25px">聚甲醛比強(qiáng)度和比剛性接近于金屬；拉伸強(qiáng)度，彎曲強(qiáng)度，耐蠕變性和耐疲勞性優(yōu)異。蘇州POM供應(yīng)商</p><p style="text-indent:25px">聚甲醛改性技術(shù)：聚甲醛綜合性能優(yōu)越，但其分子排列規(guī)整，在成型加工過(guò)程中易結(jié)晶，導(dǎo)致其韌性差、延展性差、缺口沖擊強(qiáng)度低。同時(shí)，聚甲醛熱穩(wěn)定性較差，表面硬度低，在摩擦過(guò)程中容易發(fā)生黏著磨損，不能滿足實(shí)際生產(chǎn)要求，限制了聚甲醛在工業(yè)生產(chǎn)中的應(yīng)用。為了改進(jìn)聚甲醛性能，擴(kuò)大其應(yīng)用領(lǐng)域，對(duì)聚甲醛的改性也必不可少。因此，聚甲醛的改性技術(shù)也是其研究領(lǐng)域的重要方向。聚甲醛改性技術(shù)分為物理改性和化學(xué)改性。物理改性是指通過(guò)熔融共混的方式，將共混物料按照預(yù)先設(shè)計(jì)好的改性配方通過(guò)擠出機(jī)熔融共混擠出，提高聚甲醛某些性能指標(biāo)?；瘜W(xué)改性主要是在化學(xué)合成過(guò)程中，通過(guò)分子結(jié)構(gòu)設(shè)計(jì)，改變共聚單體的種類，或添加第三單體從而獲得滿足需求的聚甲醛產(chǎn)品?；瘜W(xué)改性難度較高，而物理改性技術(shù)難度較小，易于實(shí)施，因此目前工業(yè)化的聚甲醛改性主要以物理改性為主，包括增韌改性、增強(qiáng)改性、耐磨改性、阻燃改性、熱穩(wěn)定性和耐候性改性、防靜電改性等。蘇州POM供應(yīng)商</p><p
