PTFE high-temperature jira (PTFE-yakavharidzirwa 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 / alkalis), reactor uye matangi linings (inodzivirira simbi kukora, kuchenesa nyore), mabhegi ekusefa ekuora gasi (kusvika 260 ° C), anti-corrosion yekuwedzera, machira ekuburitsa, majoini ekuburitsa machira. composite molding, uye yemagetsi/thermal insulation wraps. FDA uye UL mamakisi aripo.

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.

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. Mucheka usina kurapwa unotungamira kune delamination, kutubukira, uye hupenyu hupfupi hwesevhisi.

Kuchenesa uye kugadzirisa kwakakodzera kunowedzera hupenyu hwePTFE high-temperature jira. Kuchenesa mushure mekushandisa uye mushure mekutonhora. Shandisa mabhurashi akapfava, simbi dzisina divi, kana doro kuitira tsvina. Usamboshandisa yakasimba asidhi/alkalis, bleach, kana metal scrapers. Yenguva dzose silicone mafuta lubrication inoderedza kupfeka. Tevedzera nhungamiro idzi kudzivirira kukuvadzwa kwejasi.
