Iyini i-PTFE mesh? Futhi yiziphi izinhlelo zokusebenza ezithile ze-PTFE mesh embonini?

I-PTFE mesh iyinto ene-mesh eyenziwe nge-polytetrafluoroethylene (PTFE). Inezakhiwo eziningi ezinhle kakhulu:

1. Ukumelana nokushisa okuphezulu:I-PTFE mesh ingasetshenziswa ebangeni elibanzi lokushisa. Ingagcina ukusebenza okuhle phakathi kuka-180℃ no-260℃, okwenza kube usizo kakhulu kwezinye izindawo zokushisa okuphezulu njengokuhlunga nokuvikela. Isibonelo, emishinini yokuhlunga igesi yomoya yamanye ama-oven ezimboni,I-PTFE meshingamelana nomthelela wegesi yomoya oshisayo oshisayo ngaphandle kokushintsha noma ukulimaza emazingeni okushisa aphezulu njengezinto ezivamile.

2. Ukuqina kwamakhemikhali:Ayigqwali neze yizinto zamakhemikhali. Kungakhathaliseki ukuthi iyi-asidi enamandla, i-alkali enamandla noma i-organic solvent, kunzima ukugqwala i-PTFE mesh. Ekuhluzweni kwamapayipi embonini yamakhemikhali, ukuvikelwa kwezitsha zokusabela kwamakhemikhali, njll., i-PTFE mesh ingavimbela ngempumelelo ukugqwala kwezinto zamakhemikhali futhi yandise impilo yesevisi yemishini. Isibonelo, enkambisweni yokukhiqiza i-sulfuric acid, i-PTFE mesh esetshenziselwa ukuhlunga inkungu ye-sulfuric acid ngeke igqwale yi-sulfuric acid futhi ingaqeda umsebenzi wokuhlunga kahle.

3. Isilinganiso sokungqubuzana esiphansi:Ubuso be-PTFE mesh bubushelelezi kakhulu futhi bunomkhawulo wokungqubuzana ophansi kakhulu. Lokhu kwenza ukuthi isebenze kahle kwezinye izimo zokusetshenziswa ezidinga ukungqubuzana okuphansi. Isibonelo, ezimbozweni zokuvikela zezinye izingxenye zemishini, i-PTFE mesh inganciphisa ukungqubuzana phakathi kwezingxenye zemishini nezembozo zokuvikela, inciphise ukuguguleka, futhi ithuthukise ukusebenza kahle kwezingxenye zemishini.

4. Ukufakwa kahle kukagesi:Kuyizinto zokuvikela ugesi ezinhle kakhulu. Ekuvikeleni imishini kagesi, ekuvikeleni ukuvikela ugesi kwezintambo nezintambo, njll., i-PTFE mesh ingadlala indima enhle yokuvikela ugesi. Isibonelo, engqimbeni yokuvikela ugesi yezinye izintambo ezinamandla aphezulu, i-PTFE mesh ingavimbela ukuvuza kwamanje futhi iqinisekise ukuphepha kokudluliselwa kwamandla.

5. Ukuphefumula kanye nokuvuleka kwamanzi:Ngokwezinqubo ezahlukene zokukhiqiza, i-PTFE mesh ingenziwa ibe imikhiqizo enokuphefumula okuhlukile kanye nokuvuleka kwamanzi okuhlukile. Kwezinye izingubo eziphefumulayo nezingenamanzi, i-PTFE mesh ingavimba ukungena kwama-molecule amanzi ngenkathi ivumela umhwamuko wamanzi ukuba udlule, ugcine umuntu ogqokile omile futhi ekhululekile.

Yiziphi izinhlelo zokusebenza ezithile ze-PTFE mesh embonini?

I-PTFE mesh inezinhlobo eziningi zezicelo ezithile zezimboni. Nazi ezinye zezindawo eziyinhloko zokusetshenziswa:

1. Imboni yamakhemikhali

Ukuhlanzwa kwegesi kanye nokuhlunga uketshezi: I-PTFE mesh ivame ukusetshenziswa ezinhlelweni zokuhlunga ngamakhemikhali ngenxa yokumelana kwayo okuhle kakhulu nokugqwala kanye nezakhiwo zayo ezinganamatheli. Ingaphatha ngempumelelo imithombo egqwalisayo, enobuthi futhi eyingozi.

Ukuvikelwa kwamapayipi kanye nemishini: Izinto ze-PTFE zisetshenziselwa ukukhiqiza amapayipi, amavalvu, amaphampu kanye nezivalo ukuvikela imishini ekugqwaleni ngamakhemikhali.

2. Imboni yokudla kanye nemithi

Ukuhlunga komoya noketshezi: I-PTFE mesh ayinabo ubuthi, ayinaphunga futhi kulula ukuyihlanza. Isetshenziswa kabanzi ekuhlungeni umoya ezitshalweni zokucubungula ukudla kanye nasekuhlungeni uketshezi ezinqubweni zokukhiqiza imithi.

Ukumbozwa kwemishini kanye nezivalo: Embozweni wangaphakathi kanye nezivalo zemishini yokucubungula ukudla, izinto ze-PTFE ziqinisekisa ukuphepha kokudla kanye nokuqina kwemishini.

3. Insimu yokuvikela imvelo

Ukwelashwa kwegesi engcolile kanye nokwelashwa kwendle: I-PTFE mesh isetshenziswa kabanzi ekwelapheni indle kanye nokwelashwa kwegesi engcolile, futhi ingahlunga ngempumelelo amanzi angcolile kanye negesi engcolile equkethe izinto ezibola kakhulu njenge-fluoride ne-chloride.

Ukulawulwa kokungcoliswa kwentuthu yezimboni: Izikhwama zokuhlunga ze-PTFE zisebenza kahle ekuhlungeni intuthu emazingeni okushisa aphezulu ezimbonini ezifana nokuncibilikisa insimbi, ukukhiqizwa kwesimende kanye nokukhiqizwa kwamandla okushisa. Zingamelana namazinga okushisa aphezulu afinyelela ku-260°C, futhi zinokunemba okuphezulu kokuhlunga kanye nokusebenza okuhle kokuhlanza.

4. Imboni kawoyela negesi

Uhlelo lokuhlunga uwoyela negesi: I-PTFE mesh ivame ukusetshenziswa ezinhlelweni zokuhlunga ngesikhathi sokukhipha uwoyela negesi, ukucubungula kanye nokuthuthwa ngenxa yokumelana kwayo nokushisa okuhle kakhulu kanye nokuqina kwamakhemikhali.

5. Imboni yamandla

Amandla enuzi nomoya: Ekuhluzweni kwamagesi anomsakazo ezitshalweni zamandla enuzi kanye nasekuhluzweni komoya kuma-turbine omoya, i-PTFE mesh isibe yinto efanelekile yokuhlunga ngenxa yezakhiwo zayo zikagesi ezinhle kakhulu kanye nokungashi.

6. Insimu yezindiza

Uhlelo lokuhlunga igesi nolwelwesi: I-PTFE mesh isetshenziswa kabanzi ezinhlelweni zokuhlunga igesi nolwelwesi ezindizeni nasemkhathini ngenxa yezakhiwo zayo zikagesi ezinhle kakhulu kanye nokungashi.

7. Ezinye izinhlelo zokusebenza

Imishini kagesi kanye nekagesi: Izakhiwo zokuvikela ugesi zezinto ze-PTFE zenza ukuthi zisetshenziswe kabanzi ekuvikeleni ikhebula, amabhodi wesekethe aphrintiwe kanye nezingxenye zokuvikela ugesi zemishini enamandla aphezulu.

Amadivayisi ezokwelapha: Ukuhlanzeka okuphezulu kwe-PTFE kanye nokumelana namakhemikhali kwenza kube yinto efanelekile yamadivayisi ezokwelapha afana nama-catheter, ama-valve kanye nezixhumi.

I-PTFE mesh idlala indima engenakuphikwa emikhakheni eminingi yezimboni ngenxa yokumelana kwayo nokushisa okuphezulu, ukumelana nokugqwala, ukungqubuzana okuphansi kanye nezakhiwo ezinganamatheli.
