Yintoni i-PTFE mesh? Kwaye zeziphi izicelo ezithile ze-PTFE mesh kushishino?

I-PTFE mesh yimathiriyeli yemesh eyenziwe nge-polytetrafluoroethylene (PTFE). Ineempawu ezininzi ezintle:

1.Ukumelana nobushushu obuphezulu:Imesh ye-PTFE ingasetyenziswa kuluhlu olubanzi lobushushu. Inokugcina ukusebenza kakuhle phakathi kwe--180℃ kunye ne-260℃, eyenza ibe luncedo kakhulu kwiindawo ezithile zobushushu obuphezulu ezifana nokuhluzwa kunye nokukhusela. Umzekelo, kwisixhobo sokuhluza igesi ye-flue yamanye amaziko oshishino,PTFE umnathainokumelana neempembelelo zerhasi yobushushu obuphezulu ngaphandle kokonakala okanye ukonakalisa kumaqondo obushushu aphezulu njengezinto eziqhelekileyo.

2.Uzinzo kwiChemical:Ayinakonakala nakweyiphi na imichiza. Nokuba yiasidi eyomeleleyo, i-alkali eyomeleleyo okanye isinyibilikisi se-organic, kunzima ukugqwala umnatha we-PTFE. Kwi-filtration yepayipi yoshishino lweekhemikhali, ukukhuselwa kwezikhongozeli zokuphendula iikhemikhali, njl., i-PTFE mesh inokuthintela ngokufanelekileyo ukubola kwezinto zamakhemikhali kunye nokwandisa ubomi benkonzo yezixhobo. Ngokomzekelo, kwinkqubo yokuvelisa i-asidi ye-sulfuric, i-mesh ye-PTFE esetyenziselwa ukucoca inkungu ye-sulfuric acid ayiyi kugqweswa yi-asidi ye-sulfuric kwaye inokugqiba umsebenzi wokuhluza kakuhle.

3.I-coefficient yokhuhlane ephantsi:Umphezulu we-PTFE mesh ugudile kakhulu kwaye unomlinganiso ophantsi kakhulu wokukhuhlana. Oku kuyenza isebenze kakuhle kwezinye iimeko zesicelo ezifuna ukukhuhlana okuphantsi. Umzekelo, kwizigqubuthelo zokhuselo zamanye amalungu oomatshini, i-PTFE mesh inokunciphisa ukukhuhlana phakathi kwamalungu oomatshini kunye nezikhuselo ezikhuselayo, ukunciphisa ukuguga, kunye nokuphucula ukusebenza kakuhle kwamalungu oomatshini.

4.Ukufakwa kakuhle kombane:Yimathiriyeli efanelekileyo kakhulu yokugquma umbane. Ekukhuselweni kwezixhobo ze-elektroniki, ukukhuselwa kwe-insulation yeengcingo kunye neentambo, njl., i-PTFE mesh inokudlala indima efanelekileyo yokugquma. Umzekelo, kwi-insulation layer ye-high-voltage cables, i-PTFE mesh inokuthintela ukuvuza kwangoku kwaye iqinisekise ukhuseleko lokuhanjiswa kwamandla.

5.Ukuphefumla kunye nokungena kwamanzi:Ngokweenkqubo ezahlukeneyo zemveliso, i-PTFE mesh inokwenziwa kwiimveliso ezinokuphefumla okwahlukileyo kunye nokungena kwamanzi. Kwezinye iimpahla eziphefumlayo nezingangeni manzi, i-PTFE mesh inokuthintela ukungena kweamolekyu zamanzi ngelixa ivumela umphunga wamanzi ukuba udlule, igcina umnxibi omile kwaye ekhululekile.

Zeziphi izicelo ezithile ze-PTFE mesh kushishino?

I-PTFE mesh inoluhlu olubanzi lwezicelo zemizi-mveliso ezithile. Nazi ezinye zeendawo eziphambili zesicelo:

1. Ishishini lemichiza

Ukucocwa kwegesi kunye nokuhluzwa kolwelo: I-PTFE mesh isoloko isetyenziswa kwiinkqubo zokuhluza iikhemikhali ngenxa yokumelana nokugqwesa kwayo okugqwesileyo kunye neempawu ezingabambekiyo. Inokuphatha ngokufanelekileyo i-corrosion, high-viscosity, i-media eyityhefu kunye neyingozi.

Ukhuseleko lombhobho kunye nezixhobo: Izinto ze-PTFE zisetyenziselwa ukwenza imibhobho, iivalvu, iimpompo kunye nezitywina zokukhusela izixhobo ekudlekeni ngamachiza.

2. Ishishini lokutya kunye namayeza

Ukuhluzwa komoya kunye nolwelo: I-PTFE mesh ayinatyhefu, ayinavumba kwaye kulula ukuyicoca. Isetyenziswa ngokubanzi ekuhluzweni komoya kwizityalo zokulungisa ukutya kunye nokucoca ulwelo kwiinkqubo zokuvelisa amayeza.

Izixhobo zokugquma izixhobo kunye nokutywinwa: Kwimpahla yangaphakathi kunye nokutywinwa kwezixhobo zokulungisa ukutya, izinto ze-PTFE ziqinisekisa ukhuseleko lokutya kunye nokuqina kwezixhobo.

3. Ibala lokukhuselwa kokusingqongileyo

Ukucocwa kwerhasi yenkunkuma kunye nokucocwa kogutyulo: Imesh ye-PTFE isetyenziswa kakhulu kunyango lwelindle kunye nonyango lwerhasi yenkunkuma, kwaye inokucoca ngokufanelekileyo amanzi amdaka kunye nerhasi eyinkunkuma enezinto ezonakalisa kakhulu ezifana nefluoride kunye nekloridi.

Ulawulo lokungcoliseka komsi kwimizi-mveliso: Iingxowa zokucoca ze-PTFE zisebenza kakuhle ekuhluzweni komsi wobushushu obuphezulu kumashishini afana nokunyibilikiswa kwentsimbi, ukwenziwa kwesamente kunye nokuvelisa amandla ashushu. Ziyakwazi ukumelana namaqondo aphezulu ukuya kwi-260 ° C, kwaye zibe nokuchaneka okuphezulu kokucoca kunye nokusebenza kakuhle kokucoca.

4. Ishishini leoli negesi
