Yakawedzerwa fiberglass jira (yakawanda shinda yeshinda) inosiyana zvakanyanya kubva kune yakajairwa fiberglass jira mune yeshinda chimiro. Kuburikidza ne-high-pressure air jet treatment, inoenderera mberi girazi filaments inoparadzaniswa, crimped, uye fluffed kuita voluminous, donje-seshinda. Izvi zvinogadzira jira rakakora, rakapfava nepamusoro pekupisa kwemafuta (akavharirwa mhepo akaturikidzana), kuenderana kuri nani, kusefa kwepamusoro, uye nekunatsiridza kubvarura/kuchinjika kuramba - pamubhadharo wesimba rakaderera zvishoma. Inoshandiswa kune yakakwira-tembiricha gaskets, pombi wraps, mabhegi ekusefa, uye zvisimbiso zveovheni.

PTFE high-temperature fabric (PTFE-coated fiberglass) inenge ine makemikari inert, asi zvimwe zvinhu zvinokonzera kuora mumamiriro ezvinhu chaiwo. Kurwisa kwakananga kwePTFE kunoitika nesimbi yakanyungudutswa yealkali (sodium, potassium), yakasimba fluorinating agents (F₂, ClF₃) pakupisa kwepamusoro, uye alkali yakanyungudutswa yakasimba pamusoro pe300°C. Kuora kusina kunanga kunoitika kana hydrofluoric acid (HF), inopisa yakadzika alkalis, kana inopisa phosphoric acid ikapinda zvakakanganisika zvekupfeka uye kurwisa iyo fiberglass substrate. Nekunyanyisa kemikari sevhisi, shandisa yakachena PTFE firimu isina fiberglass.

PTFE high-temperature jira (PTFE-yakavharwa fiberglass) ine yakanakisa kupisa kuvhunduka kwekudzivirira mukati meyakajairika kushanda kwayo kwe -70°C kusvika 260°C. Inogona kushivirira kukurumidza tembiricha bhasikoro, semuenzaniso, kufamba kubva -50 ° C firiza kuenda 260 ° C inopisa muchina. Magiredhi ePremium anopona nekukasira kutonhora kubva pa260°C kusvika pa10°C mvura. Zvisinei, kuvhundutsa zvinhu kubva tembiricha pamusoro 300°C (padyo PTFE's 327°C melting point) kuchaita nokukurumidza kutsemuka uye delamination. Iyo fiberglass substrate inopa dimensional kugadzikana; iyo PTFE coating ndiyo inomisa chinhu.

PTFE high-temperature jira rinoshandiswa zvakanyanya muindasitiri yemakemikari kune zvinomwe zvakakosha zvikumbiro: flange gaskets uye pombi linings (inodzivirira yakasimba acids / alkali), reactor uye matangi linings (inodzivirira simbi kukora, kuchenesa nyore), mabhegi ekusefa ekuora gasi (kusvika 260 ° C), anti-corrosion yekuwedzera, majoini ekuburitsa, majoini ekuburitsa machira. composite molding, uye yemagetsi/thermal insulation wraps. FDA uye UL mamakisi aripo.

PTFE high-temperature fabric (PTFE-coated fiberglass) inopa zvikomborero zvina zvakakosha se-anti-corrosion lining: kemikari inertness (inopesana ne aqua regia, alkalis yakasimba, zvinonyungudutsa), yakawanda yekushisa (-70 ° C kusvika 260 ° C inoenderera mberi, 350 ° C peak), dimensional kugadzikana (<0.5 uye kuchenesa kwepamusoro-kureba), (kudzikamisa-kureba kwepamusoro), kuchenesa (kureba-kureba). Inoshandiswa mumakemikari mapaipi, desulfurization shongwe, pickling matangi, uye chikafu / mishonga yemishonga. FDA mamakisi aripo.

PTFE high-temperature jira rinopa zvitanhatu zvakakosha zvakakosha sebhanhire rekudhinda: non-stick surface (printing paste uye inki kusunungurwa zvakachena), 260 °C heat resistance (inoshanda kuomesa), dimensional kugadzikana (<0.5% elongation, kunyatsonyoreswa), kemikari inertness (inopikisa corrosive pastes), low friction, customothbler anti-static). Yakanakira kudhinda skrini, kudhinda kwedhijitari, uye kupisa kwekufambisa maapplication.

Anti-static PTFE high-temperature jira rinobatanidza iyo isiri-tsvimbo, inodzivirira kupisa (260 ° C), uye kemikari inert zvimiro zveyeja PTFE ine static-dissipative performance. Zvishandiso zvakakosha: kugadzirwa kwemagetsi (PCB lamination, component handling), PV module lamination (inodzivirira kukuvadzwa kweESD kune maseru ezuva), chikafu nekugadzirwa kwemishonga (ESD-yakachengeteka baking liners), makemikari zvirimwa (anti-corrosion, anti-static ducting), uye machira / maindasitiri ekudhinda. Kuramba kwepamusoro kazhinji 10⁶–10⁹ Ω.

PTFE yakakwirira-tembiricha yejira sevhisi hupenyu hunosiyana zvakanyanya nekushandisa. Chemical anti-corrosion lining inogona kugara makore matatu+ (4x kureba kupfuura rabha). Chikafu chekubika matireyi mwedzi yapfuura nekuderera kudiki. Industrial conveyor mabhandi anopfeka kubva mukukweshana. PV lamination (150°C, EVA kuonana) ine upenyu huri pakati nepakati. Heavy friction applications (abrasive discs) ine hupenyu hupfupi. Zvinhu zvakakosha: kudzora tembiricha (gara ≤260 ° C), dzivirira kutsemuka kwakapinza, kucheneswa nguva dzose, uye kutsiva panguva yakakodzera kana blistered kana yero.

PTFE high-temperature jira rinodzikama kusvika ku300°C, asi mumoto rinoora uye rinobudisa magasi ane muchetura zvikuru: hydrogen fluoride (HF) (corrosive, pulmonary edema) uye perfluoroisobutylene (PFIB) (isina ruvara, isinganhuhwi, ~10x ine muchetura kupfuura phosgene, nododo). Zvakare kabhoni monoxide, PFOA zvisaririra, uye kutsvaga 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 inoendesa microwaves isingatore simba, inopikisa 260°C, uye ine nzvimbo isina tsvimbo. Zvishandiso zvinosanganisira ma microwave ekubikira, mabhandi ekuomesera emuindasitiri, mareactor linings ekugayiwa kwemakemikari, uye microwave popcorn bag liner. FDA mamakisi anowanikwa kune chikafu chekubata.
