改性四氟板
PK-GS1610改性四氟板又叫填充聚四氟乙烯板,是用聚四氟乙烯樹脂添加一定量填充劑,如玻璃纖維,青銅粉,二硫化鉬,石墨,碳纖維等,經(jīng)高速混合均勻后用模具壓制成型,再經(jīng)高溫?zé)Y(jié)制成墊片等制品或先壓制成改性四氟板后沖壓或裁切成各種四氟制品。填充聚四氟乙烯板由于在聚四氟乙烯中加入一定量的填充劑,從而大大改善了聚四氟乙烯的某些特性,特別是耐磨耗、導(dǎo)熱、抗糯變、自潤滑等方面比純聚四氟乙烯板有較明顯的改善。適用于在-180℃~+250℃溫度范圍內(nèi)的耐腐蝕、導(dǎo)熱、耐磨耗、無油潤滑、減震抗磨的密封件,潤滑傳導(dǎo)件。

為了滿足客戶對(duì)高品質(zhì)四氟墊片的需要我們引進(jìn)國外一些國外著名品牌性能優(yōu)異的膨脹四氟板和改性四氟板材料,如Gore,Garlock, Valqua,TEMAC 等可參考膨脹四氟板

本公司擁有GB2506-89、GB/T17727、HG/T20627、HG/T20606等標(biāo)準(zhǔn)全系列各種改性四氟墊片模具歡迎大家垂詢改性四氟模壓成型墊片要求厚度2mm以上。

填充四氟板性能特點(diǎn):
改性(填充)PTFE的性能與填充材料的性能、含量及制備工藝有密切關(guān)系。填充劑必須滿足:(1)填充劑在380-400℃燒結(jié)條件下穩(wěn)定;(2)填充劑粒度150µm;(3)填充劑不會(huì)吸潮;(4)在燒結(jié)條件下,填充劑自身不會(huì)簇集;(5)填充劑不與PTFE反應(yīng) 。
填充四氟板常用填充劑:石墨、二硫化鉬、陶瓷顆粒/纖維、碳纖維(CF)、玻璃微珠和玻璃纖維(GF) 、石英、硫酸鋇等
1.提高耐冷流、蠕變性能:填充石墨、玻璃微珠和玻璃纖維(GF、聚苯硫醚
2.提高耐冷流、潤滑性:填充MoS2,
3.提高導(dǎo)熱性能:填充青銅粉、鉬、鎳、等、碳纖維
4.提高耐磨性能:填充玻璃微珠和玻璃纖維(GF) 、聚酰亞胺、聚苯酯
5.提高穩(wěn)定性和減少變形:碳纖維、聚苯硫醚

填充四氟板使用行業(yè):化工、石化、煉油、氯堿、制酸、磷肥、制藥、農(nóng)藥、化纖、染化、焦化、煤氣、有機(jī)合成、有色冶煉、鋼鐵、原子能及高純產(chǎn)品生產(chǎn)(如離子膜電解),粘稠物料輸送與操作,衛(wèi)生要求高度嚴(yán)格的食品、飲料等加工生產(chǎn)部門。

填充四氟板使用設(shè)備: 管道、閥門、泵、壓力容器、熱交換器、冷凝器、發(fā)電機(jī)、空氣壓縮機(jī)、排氣管、制冷機(jī)等法蘭連接處的密封部位
