PTFE high-temperature jira (PTFE-yakavharidzirwa fiberglass) haina kusimba kuchinjika nekuti iyo fiberglass substrate inogadzika brittle. Machira matete (0.08mm) anopona mazana kusvika kuzviuru zvemapete; magiredhi anorema (> 0.25mm) anotsemuka mushure memakumi mazhinji. Satin weave inodarika plain weave. Kuti urambe uchipeta, funga yakasimba PTFE firimu kana aramid-based fabric panzvimbo.

PTFE high-temperature fabric (PTFE-coated fiberglass) inoshandiswa zvakanyanya mumucheka kudhinda uye kudhayira kupisa kupisa mabhandi ekudhinda (180-230 ° C), zvivharo zvetafura yekudhinda, kuomesa mesh mabhandi, fusing machine belt, uye roller wrapping. Nzvimbo yayo isina tsvimbo inodzivirira inki / inonamatira zvakasara, kuderedza kuchenesa nguva yekuchenesa nekuvandudza kunaka kwejira. Mabhandi asingagumi asingagumi anogonesa kuenderera mberi kwekugadzirwa.

PTFE high-temperature fabric (PTFE-coated fiberglass) is a premium filter media for a extreme conditions: flue gas dust kubvisa (simende, tsvina yekupisa, marasha boilers kusvika 260 ° C), corrosive liquid filtration (acids, alkalis, oils), chikafu/mishonga inosvibisa filtration, uye HEPA cleanroom filters. Isiri-tsvimbo inodzivirira guruva caking uye inobvumira kuchenesa nyore. Membrane-laminated mamakisi anowana ultra-low emissions.

PTFE high-temperature jira rinochengetedza yakanakisa magetsi ekudzivirira kubva -180°C kusvika 260°C: volume resistivity >10¹³ Ω·cm pa200°C, dielectric inogara yakagadzikana pa2.0-2.1. Pamusoro pe260 ° C, PTFE inopfava, inoora pamusoro pe327 ° C, ichirasikirwa nekudzivirira zvachose. Pazasi pe 0°C, kuvharisa kunonatsiridza asi kupfeka kunoita brittle. Gara mukati me260 ° C kuitira kushanda kwakavimbika.

PTFE high-temperature fabric (PTFE-coated fiberglass) yakanakira mabhandi ekutakura chikafu nekuda kwekupisa kwayo 260°C, -70°C kutonhora kuchinjika, kusinga tsvinda, uye kutevedzera FDA. Mashandisirwo akakosha: maovheni ekubheka (mabhisikiti, chingwa, pitsa), kutakura chikafu chakakangwa, mitsara yekutonhodza maswiti, tunnel dzinoomesa nechando, zvivhariso zvekupisa, uye kuputira. Inoderedza tsvina uye nguva yekuchenesa.

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 mukusabatisa, kusapfeka, 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 kemikari 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.
