Yintoni i-PTFE mesh? Kwaye zeziphi iindlela ezithile zokusebenzisa i-PTFE mesh kushishino?

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

1. Ukumelana nobushushu obuphezulu:I-PTFE mesh ingasetyenziswa kumanqanaba obushushu abanzi. Ingagcina ukusebenza kakuhle phakathi kwe-180℃ kunye ne-260℃, nto leyo eyenza ukuba ibe luncedo kakhulu kwiindawo ezithile zobushushu obuphezulu ezifana nokuhluza kunye nokukhusela. Umzekelo, kwizixhobo zokucoca igesi yolwelo kwezinye izitofu zoshishino,umnatha we-PTFEinokumelana nefuthe legesi yolwelo olushushu kakhulu ngaphandle kokuyiguqula okanye ukonakalisa kumaqondo obushushu aphezulu njengezinto eziqhelekileyo.

2. Uzinzo lwekhemikhali:Ayinakonakala kakhulu zizinto zeekhemikhali. Nokuba yi-asidi enamandla, i-alkali enamandla okanye i-organic solvent, kunzima ukubola i-PTFE mesh. Kwi-pipeline filtration yeshishini leekhemikhali, ukukhuselwa kwezikhongozeli ze-chemical reaction, njl.njl., i-PTFE mesh inokuthintela ngempumelelo ukubola kwezinto zeekhemikhali kwaye yandise ubomi benkonzo yezixhobo. Umzekelo, kwinkqubo yokuvelisa i-sulfuric acid, i-PTFE mesh esetyenziselwa ukucoca inkungu ye-sulfuric acid ayizukubola yi-sulfuric acid kwaye ingawugqiba kakuhle umsebenzi wokucoca.

3. I-coefficient ephantsi yokungqubana:Umphezulu we-PTFE mesh uthambile kakhulu kwaye une-coefficient ephantsi kakhulu yokungqubana. Oku kuyenza isebenze kakuhle kwezinye iimeko zokusetyenziswa ezifuna ukungqubana okuphantsi. Umzekelo, kwizigqubuthelo zokukhusela zezinye iindawo zoomatshini, i-PTFE mesh inokunciphisa ukungqubana phakathi kweendawo zoomatshini kunye nezigqubuthelo zokukhusela, inciphise ukuguguleka, kwaye iphucule ukusebenza kakuhle kweendawo zoomatshini.

4. Ubushushu obuhle bombane:Yinto efanelekileyo kakhulu yokukhusela umbane. Ekukhuseleni izixhobo ze-elektroniki, ekukhuseleni iingcingo kunye neentambo zokukhusela umbane, njl.njl., i-PTFE mesh inokudlala indima entle yokukhusela umbane. Umzekelo, kumaleko wokukhusela umbane kwezinye iintambo ze-voltage ephezulu, i-PTFE mesh inokuthintela ukuvuza kwamandla kwaye iqinisekise ukhuseleko lokudluliselwa kwamandla.

5. Ukuphefumla kakuhle kunye nokuvuleka kwamanzi:Ngokweenkqubo ezahlukeneyo zemveliso, i-PTFE mesh inokwenziwa ibe ziimveliso ezinokuphefumla okwahlukeneyo kunye nokuvuleka kwamanzi okwahlukeneyo. Kwezinye iimpahla ezinokuphefumla nokungangeni manzi, i-PTFE mesh inokuthintela ukungena kweemolekyuli zamanzi ngelixa ivumela umphunga wamanzi ukuba udlule, igcine umntu onxibe eyomile kwaye ekhululekile.

Ziziphi iindlela ezithile zokusebenzisa i-PTFE mesh kushishino?

I-PTFE mesh ineentlobo ngeentlobo zezicelo ezithile zoshishino. Nazi ezinye zeendawo eziphambili zokusetyenziswa:

1. Ishishini leekhemikhali

Ukucocwa kwegesi kunye nokuhluzwa kolwelo: I-PTFE mesh idla ngokusetyenziswa kwiinkqubo zokucoca iikhemikhali ngenxa yokumelana kwayo nokugqwala kunye neempawu zayo ezinganamatheliyo. Ingaphatha ngokufanelekileyo izinto ezigqwalisayo, ezinobuthi obuphezulu, ezinobuthi nezinobungozi.

Ukhuseleko lwemibhobho nezixhobo: Izixhobo ze-PTFE zisetyenziselwa ukwenza imibhobho, iivalvu, iimpompo kunye nezitywino ukukhusela izixhobo ekungcoleni ziikhemikhali.

2. Ishishini lokutya kunye namayeza

Ukucoca umoya nolwelo: I-PTFE mesh ayinatyhefu, ayinavumba kwaye kulula ukuyicoca. Isetyenziswa kakhulu ekuhluzeni umoya kwiindawo zokulungisa ukutya nasekuhluzeni ulwelo kwiinkqubo zemveliso yamayeza.

Ukugquma nezixhobo: Kwigquma zangaphakathi kunye nezitywino zezixhobo zokucubungula ukutya, izixhobo ze-PTFE ziqinisekisa ukhuseleko lokutya kunye nokuqina kwezixhobo.

3. Intsimi yokukhusela okusingqongileyo

Unyango lwegesi yenkunkuma kunye nonyango lwelindle: I-PTFE mesh isetyenziswa kakhulu ekunyangweni kwelindle kunye nonyango lwegesi yenkunkuma, kwaye inokucoca ngempumelelo amanzi amdaka kunye negesi yenkunkuma enezinto ezirhabaxa kakhulu ezifana ne-fluoride kunye ne-chloride.

Ulawulo longcoliseko lomsi kwimizi-mveliso: Iingxowa zesihluzo ze-PTFE zisebenza kakuhle ekuhluzweni komsi obushushu obuphezulu kwimizi-mveliso efana nokunyibilikisa intsimbi, ukuvelisa isamente kunye nokuveliswa kwamandla obushushu. Ziyakwazi ukumelana nobushushu obuphezulu ukuya kuthi ga kwi-260°C, kwaye zichanekile kakhulu ekuhluzweni kunye nokusebenza kakuhle kokucoca.
