Warp uye weft density yefiberglass jira rinotarisa PTFE yakakwirira-tembiricha machira kuita. Yakakwira density inowedzera simba rekusimba uye kutsvedzerera kwepasi asi inoderedza simba rekubvarura (inverted U-curve), kuchinjika, uye kupinda mukati. Optimal density zviyero kupinza, kuramba kubvarura, kuchinjika, uye kupera kwepamusoro. Low density inokodzera kubhenda kunochinja; high density ye-non-stick uye insulation.

Calendering - kudzvanya PTFE-yakavharwa jira pakati peanopisa girazi rollers pa360-380 ° C - zvinonyanya kushandura morphology yepasi, kuburitsa zvimiro, kusamira, uye mashandiro emuchina. Iyo inoderedza roughness kubva kuRa 0.5-1.0 μm kusvika ku <0.05 μm, inovhara pinholes, inovandudza kupfeka kusagadzikana, asi inoderedza simba rekubvarura uye kushanduka. Zvakakosha pakusunungura liners uye magetsi ekudzivirira.

PTFE high-temperature jira uye silicone jira zvese zvinoshandisa fiberglass jira sechigadziko asi chinosiyana mukupfeka zvinhu (PTFE resin vs silicone rubber). PTFE inokunda mukusanamatira, kupfeka kuramba, uye makemikari kuramba kusvika 260°C. Silicone jira rinopa kuchinjika kwepamusoro, kuvharwa kwemagetsi, uye kudzivirira moto (kusvika 230 ° C). Sarudza zvichibva pane zvaunokoshesa.

PTFE yakakwira-tembiricha jira (PTFE membrane zvinhu) isarudzo yekutanga yekusimba kwekuvaka. Mabhenefiti akakosha: makore makumi matatu+ ehupenyu hwekunze, kuzvichenesa pamusoro (mvura inonaya inosuka tsvina), kutapurirana mwenje munyoro (6-13%), Chiyero chemoto cheKirasi A, uye simba rakaita sesimbi riri pasi pe1.5 kg/m². Inoshandiswa munhandare, nhandare dzendege, uye zvivakwa zvemifananidzo pasi rese.

PTFE high-temperature jira inopa yakasarudzika makemikari kuramba, inoshingirira maasidhi akasimba, alkalis, organic solvents, uye magasi anoparadza. Ichi chinyorwa chinodonongodza zvinhu zvayo zvinoramba, zvisingakwanisi (simbi yakanyungudutswa yealkali, yakasimba fluorinating agents), uye zvinhu zvakakosha senge tembiricha, kutarisisa, uye kushushikana kwemagetsi.

PTFE impregnation haina kuganhurirwa kune fiberglass jira. Ichi chinyorwa chinosuma 7 mamwe ma substrates - aramid, carbon fiber, PBI, porous simbi, graphite, asbestos (pased out), uye ceramic fillers - ine maitiro avo maitiro, zvakanakira, zvisingakwanisi, uye zvakakosha mashandisirwo.

Ichi chinyorwa chinotsanangura kuti sei alkali-isina fiberglass jira riri iro rinofarirwa substrate yePTFE yakakwirira-tembiricha jira. Iyo inovhara kemikari kusungirirwa kuburikidza ne silane coupling agents uye akakosha emuviri zvimiro senge kugadzikana kwemafuta, kugadzikana kwedimensional, uye kuramba kwecorrosion - kuve nechokwadi chekuita kwenguva refu munzvimbo dzakaoma.
