Pfeka Kupikisa kwePTFE High-Temperature Fabric

Jiangsu Aokai New Materials, inyanzvi yekugadzira PTFE high-temperature machira, anotsanangura sezvinotevera:

Iko kushandiswa kwakapararira kwePTFE yakakwirira-tembiricha machira muindasitiri inotakura, michina yekurongedza, kuomeswa kwechikafu uye mamwe minda inofananidzwa zvakanyanya nekunaka kwayo kupfeka kuramba. Pamusoro pePTFE high-temperature jira yakaputirwa nepolytetrafluoroethylene (PTFE), iyo ine yakanyanya kuderera coefficient of friction, kazhinji 0.05-0.1 , chinenge chikamu chimwe chete mugumi chenzvimbo dzesimbi dzakajairwa. Ichi chivakwa chinopa PTFE yakakwira-tembiricha jira ine yakasarudzika yekuzora. Kana zvinhu zvinotsvedza kana kufamba nepamusoro pepamusoro payo, kuramba kwekubata kudiki, zvinonyatso dzikisa kukweshera kwemakanika uye kupfeka.

Mumiyedzo chaiyo yemamiriro ekushanda, kupfekedzwa kwejira rePTFE kwepamusoro-tembiricha kunopeta nekatatu pane  zvezvakajairwa machira. Muindasitiri, mukana uyu unowanzo shandiswa kutsiva echinyakare simbi inotakura gaskets kana kutungamira njanji zvinhu, kuderedza friction ruzha uye kupfeka kwechikamu panguva yekushanda kwemidziyo. Zvimwe zvepamusoro-simba zvePTFE zvemhando yepamusoro-tembiricha zvigadzirwa zvemachira zvinosimbiswa zvakare negraphene composite layers kana simbi mesh skeletons kusimudzira kukwenya kuramba uye kugadzikana kwechimiro. Naizvozvo, mukati mehupenyu hwayo hwakagadzirirwa sevhisi, PTFE yakakwirira-tembiricha jira inopa yakavimbika kupfeka kuramba pasi pekukwesha kubva kune zvakajairwa zvinochinjika zvinhu senge machira, mapepa uye epurasitiki mafirimu.

Zvisinei, kupikisa kupfeka kwePTFE high-temperature yejira ine muganhu wakajeka wemuviri: kushanda kwayo kunoenderana zvachose nekuvimbika kwepamusoro PTFE coating . Kana yambokweshwa kakawanda nemicheto yesimbi yakapinza kana zvidimbu zvakaoma, chimiro chekuputira chinozokuvadzwa.

I. Kurasikirwa Kwakakwana Kwekuita Kusina-Stick

Iyo isiri-tsvimbo midziyo yePTFE yakakwirira-tembiricha jira inouya zvachose kubva pamusoro pePTFE coating. Nesimba rakadzika kwazvo repamusoro, iyo yekupfekedza inodzinga zvinenge zvese zvinhu zvinonamira, zvinosanganisira zvinonamira, ingi, mapurasitiki akanyungudutswa uye masara echikafu.

Degradation performance : Kana iyo PTFE coating yapera, iyo yakaoma, microporous fiberglass substrate iri pasi inoburitswa pachena. Zvinamira izvo zvakatanga kudzingwa zvinopinda uye zvakanamira zvakasimba kune maburi efiberglass.

Mhedzisiro : Iyo PTFE jira rinorasikirwa nepakati-yakachena-yakachena uye isina-tsvimbo mabasa. Zvisaririra zvepasi zvichaungana nekukurumidza, zvichikanganisa kutakura kwakajairwa uye kukurumidza kuwedzera kupfeka, zvichigadzira kutenderera kwakashata.

II. Sharp Drop in Temperature Resistance uye Kukundikana Kwemaitiro

Iyo yakayerwa tembiricha kuramba yePTFE yepamusoro-tembiricha jira (yenguva refu sevhisi pa260 °C ) inotsamira pane zvese zviri zviviri PTFE coating uye fiberglass base jira. Mushure mekupfeka kupfeka, kupisa kwekushisa kunodonha mumatanho maviri:

Kurasikirwa kwekupisa kwenguva pfupi kupisa : Nzvimbo dzakasakara dzinorasikirwa nedziviriro yePTFE. Fiberglass yakafumurwa inokurumidza kuita brittle nekuda kwekuvhunduka kwekupisa uye oxidation patembiricha iri pazasi pehukoshi hwakayerwa, zvichigadzira njodzi huru yekungoerekana yaputsika munzvimbo dzine tembiricha yepamusoro.

Substrate oxidation uye kupatsanurwa kwechimiro : Pasi pekuenderera kwekushisa kwepamusoro, fiberglass isina kudzivirirwa inopindirana neokisijeni, zvichikonzera kurasikirwa nekukurumidza kwesimba rekutanga, pulverization uye kutyoka. Mucheka uchabvaruka uye ugoparara kubva panzvimbo yakasakara, uchirasikirwa zvachose nekutendeseka kwechimiro seyepamusoro-tembiricha inotakura svikiro.

III. Concomitant Degradation yeZvimwe Zvivakwa

Uye zvakare, iyo kemikari corrosion resistance  yePTFE high-temperature jira inorasika zvakare. Kunyange zvazvo PTFE yakasimba inogona kudzivisa corrosives yakasimba yakadai se aqua regia, nzvimbo dzakasakara dzinobvumira makemikari kupinda mukati uye kurwisa fiberglass zvakananga, zvichiita kuti kukurumidza kuparara, kuzvimba uye kuderera kwakanyanya kwehupenyu hwebasa.

Kana kukuvadzwa kwekuvhara kwaonekwa, jira rePTFE rinofanirwa kugadziriswa kana kutsiviwa nekukasira kudzivirira kutadza zvachose kwebhandi rese rekutakura nekuda kwekupfeka kwenzvimbo.

Ruzivo rwuri pamusoro rwunopihwa neJiangsu Aokai New Materials Technology Co., Ltd.

Kuti uwane tsanangudzo yakadzama, mamiriro ekushandiswa uye zvigadziriso zvakagadzirirwa zvechigadzirwa chedu chizere - kusanganisira PTFE high-temperature jira, PTFE high-temperature tepi, PTFE high-temperature mesh bhandi, seamless bhandi rekugadzira bonding machine, single-sided PTFE jira, high-temperature resistant conveyor bhandi, high-temperature inotakura fiberglass, tapota taura nesu:
