特征 Features
直徑1-5mm的聚四氟乙烯模壓棒是選用聚四氟乙烯樹(shù)脂經(jīng)糊膏擠壓加工成;直徑6-200mm的棒選用懸浮聚四氟乙烯樹(shù)脂經(jīng)柱塞加工制成直徑200mm以上的棒經(jīng)模壓加工制成。
Diameter 1-5mm rods are made of polytetraflu resin by paste extrusion processing: Diameter 6-200mm rod selection suspension PTFE resin made by plunger processing Diameter more than 200mm rods by molding production
型號及規格 Types and Specifications
注:當棒直徑大于16mm時(shí),僅測試表觀(guān)密度
Note: When the diameter of rod is larger than 1 6mm, only test apparent density
主要技術(shù)指標 Main Properties:
用途App| ications
化工方面:能用作防腐資料,可制造各種防腐蝕零部件,如管子、閥門(mén)、泵及管件接頭等;ぴO備方面,可制作反應器、蒸餾塔及防腐設備的襯里和涂層。機械方面:可用作自潤滑軸承、活塞環(huán)、油封及密封圈等。自潤滑性可減少機件磨損和發(fā)熱,降低動(dòng)力消耗。電子電器方面:主要用于制造各種電線(xiàn)電纜、電池電極、電池隔膜、印刷電路板等。
Chemical: can be used as anti-corrosion materials, can manufacture a variety of anti-corrosion parts, su
as pipes, valves, pumps and fittings joints. Chemical equipment, can be produced reactor, distillation column
anti-corrosion equipment lining and coating
Mechanical: can be used as self-lubricating bearings, piston rings oil seals and seals. Self-lubrication can
duce wear and heat and reduce power consur
Electronic and electric
pects:mainly used in the manufacture of various wire and cable, battery elec
trodes, battery separator, printed circuit boards

2018受供給側改革、環(huán)保督察的影響,從上游原材料到中游氫氟酸到下游氟樹(shù)脂行業(yè),廠(chǎng)家整體開(kāi)工率不高,產(chǎn)品供應緊張,市場(chǎng)仍會(huì )處于供不應求狀態(tài),產(chǎn)量收縮,價(jià)格預計繼續上漲。
發(fā)布時(shí)間:2018-11-12我們工程都是根據HG2099來(lái)檢測聚四氟乙烯密封墊片的 “走漏量”,單端面的機械密封只是針對“走漏量”做定性檢查,我們肉眼看不到顯著(zhù)氣泡就算合格。一般我們檢測的規則是軸徑≥80mm時(shí),走漏量是≤10L/h的;軸徑≤80mm時(shí),走漏量是≤8mL/h的。
發(fā)布時(shí)間:2018-11-12聚四氟乙烯墊片失效后會(huì )產(chǎn)生泄漏,主要表現在一是密封面上有間隙。二是密封部位兩側存在壓力差。聚四氟乙烯墊片密封需要解決的是消除或減小密封面之間的間隙。
