特征 Features
直徑1-5mm的聚四氟乙烯擠出棒是選用聚四氟乙烯樹脂經(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(guī)格 Types and Specifications
注:當(dāng)棒直徑大于16mm時(shí),僅測試表觀密度
Note: When the diameter of rod is larger than 1 6mm, only test apparent density
主要技術(shù)指標(biāo) 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、泵及管件接頭等。化工設(shè)備方面,可制作反應(yīng)器、蒸餾塔及防腐設(shè)備的襯里和涂層。機(jī)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(jī)件磨損和發(fā)熱,降低動力消耗。電子電器方面:主要用于制造各種電線電纜、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(cè)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脂行業(yè)，廠家整體開工率不高，產(chǎn)品供應(yīng)緊張，市場仍會處于供不應(yīng)求狀態(tài)，產(chǎn)量收縮，價(jià)格預(yù)計(jì)繼續(xù)上漲。
發(fā)布時(shí)間：2018-11-12我們工程都是根據(jù)HG2099來檢測聚四氟乙烯密封墊片的 “走漏量”，單端面的機(jī)械密封只是針對“走漏量”做定性檢查，我們?nèi)庋劭床坏斤@著氣泡就算合格。一般我們檢測的規(guī)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產(chǎn)生泄漏，主要表現(xiàn)在一是密封面上有間隙。二是密封部位兩側(cè)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。
