PTFE high-temperature fabric (PTFE-coated fiberglass) inogara kwenguva refu kana ichichengetwa pasi pe260°C, kure nezvinopinza, uye kucheneswa nemidziyo yakapfava. Zvinhu zvikuru zvinomisa upenyu: kuderera kwekushisa kwepamusoro pe260 ° C, kupisa kwekushisa kubva kukurumidza kupisa / kutonhora, kuneta kwemagetsi kubva pakukotama uye kukakavara, kurwisa kwemakemikari kubva kusimbi yakanyungudutswa yealkali kana maoxidizers akasimba, kukuvadzwa kubva kusimbi scrapers panguva yekuchenesa, uye UV kuratidzwa kwekushandisa kunze. Hunhu hwekuputira uye substrate zvakare hune basa.

PTFE high-temperature jira rinodzikama kusvika ku300°C, asi mumoto rinoora uye rinobudisa magasi ane muchetura: hydrogen fluoride (HF) (corrosive, pulmonary edema) uye perfluoroisobutylene (PFIB) (isina ruvara, isinganhuhwi, ~10x ine muchetura kupfuura phosgene, nododo). Zvakare kabhoni monoxide, PFOA zvakasara, uye tsvaga dioxins. Masikisi ehutsi akajairika haashande; shandisa self-contained breathing apparatus (SCBA). Zviratidzo zvinogona kunonoka.

PTFE high-temperature fabric (PTFE-coated fiberglass) yakanakira microwave kudziyisa nekuti inofambisa microwaves isingatore simba, inopikisa 260°C, uye ine nzvimbo isina tsvimbo. Zvishandiso zvinosanganisira ma microwave ekubikira mabhandi, mabhandi ekuomesera emuindasitiri, mareactor linings ekugayiwa kwemakemikari, uye microwave popcorn bag liner. FDA mamakisi anowanikwa kune chikafu chekubata.

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.

Musoro wekupedzisa maajenti akaiswa kune jira refiberglass pamberi pePTFE coating yakakosha kune yekupedzisira PTFE yakakwirira-tembiricha machira kuita. Organosilane coupling agents inogadzira mabhiriji mamorekuru pakati peinorganic glass fiber uye organic PTFE, inowedzera masvuura simba kubva pa<2 N/cm kusvika 4-8+ N/cm. Kurapa kwakakodzera kunowedzerawo kupisa kupisa (260 ° C +), dielectric performance, uye makemikari kuramba. Chigadzirwa chisina kubatwa chinotungamira kune delamination, kutubukira, uye hupenyu hupfupi hwesevhisi.

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.
