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