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

I-PTFE mesh i-mesh material eyenziwe nge-polytetrafluoroethylene (PTFE). Inezici eziningi ezinhle kakhulu:

1.Ukumelana nezinga lokushisa eliphezulu:I-PTFE mesh ingasetshenziswa ebangeni lokushisa elibanzi. Ingakwazi ukugcina ukusebenza okuhle phakathi kuka -180℃ no-260℃, okuyenza isebenziseke kakhulu kwezinye izindawo zokushisa okuphezulu njengokuhlunga nokuvikela. Isibonelo, kumishini yokuhlunga igesi ye-flue yamanye amaziko ezimboni,I-PTFE meshingamelana nomthelela wegesi yokushisa ephezulu ngaphandle kokonakala noma ukulimaza emazingeni okushisa aphezulu njengezinto ezijwayelekile.

2.Ukuzinza kwamakhemikhali:Ayigqwali neze yinoma yiziphi izinto zamakhemikhali. Noma ngabe iyi-asidi eqinile, i-alkali eqinile noma i-organic solvent, kunzima ukugqwala inezikhala ze-PTFE. Ekuhlungeni amapayipi embonini yamakhemikhali, ukuvikelwa kweziqukathi zokusabela kwamakhemikhali, njll., i-PTFE mesh ingavimbela ngempumelelo ukugqwala kwezinto zamakhemikhali futhi yandise impilo yesevisi yemishini. Isibonelo, kunqubo yokukhiqiza i-sulfuric acid, i-PTFE mesh esetshenziselwa ukuhlunga inkungu ye-sulfuric acid ngeke igqwaliswe yi-sulfuric acid futhi ingaqedela umsebenzi wokuhlunga kahle.

3.Low friction coefficient:Ingaphezulu le-PTFE mesh libushelelezi kakhulu futhi line-coefficient ephansi kakhulu yokungqubuzana. Lokhu kuyenza isebenze kahle kwezinye izimo zohlelo lokusebenza ezidinga ukungqubuzana okuphansi. Isibonelo, kumakhava okuvikela ezingxenye ezithile zomshini, i-PTFE mesh inganciphisa ukungqubuzana phakathi kwezingxenye eziwumshini namakhava okuvikela, inciphise ukuguga, futhi ithuthukise ukusebenza kahle kwezingxenye eziwumshini.

4.Ukufakwa kahle kukagesi:Kuyinto enhle kakhulu yokuvikela ugesi. Ekuvikeleni okokusebenza kwe-elekthronikhi, ukuvikela ukuvikela izintambo nezintambo, njll., i-PTFE mesh ingadlala indima enhle yokuvikela. Isibonelo, kungqimba yokufakwa kwe-insulation yezinye izintambo ezinamandla kagesi, i-PTFE mesh inganqanda ukuvuza kwamanje futhi iqinisekise ukuphepha kokudluliswa kwamandla.

5.Ukuphefumula kanye nokungena kwamanzi:Ngokwezinqubo ezahlukene zokukhiqiza, i-PTFE mesh ingenziwa ibe yimikhiqizo enokuphefumula okuhlukile kanye nokungena kwamanzi. Kwezinye izingubo eziphefumulayo nezingangeni manzi, i-PTFE mesh ingavimba ukungena kwama-molecule amanzi kuyilapho ivumela umhwamuko ukuba udlule, igcine oyifakile omile futhi enethezekile.

Yiziphi izinhlelo zokusebenza ezithile ze-PTFE mesh embonini?

I-PTFE mesh inohlu olubanzi lwezinhlelo zokusebenza ezithile zezimboni. Nazi ezinye zezindawo eziyinhloko zokufaka isicelo:

1. Imboni yamakhemikhali

Ukuhlanzwa kwegesi kanye nokuhlunga okuwuketshezi: I-PTFE mesh ivamise ukusetshenziswa ezinhlelweni zokuhlunga amakhemikhali ngenxa yokumelana nokugqwala okuhle kakhulu kanye nezindawo ezingezona izinti. Ingakwazi ukuphatha kahle imidiya ebolayo, i-high-viscosity, enobuthi neyingozi.

Ukuvikelwa kwamapayipi nezinto zokusebenza: Izinto ze-PTFE zisetshenziselwa ukwakha amapayipi, amavalvu, amaphampu nezigxivizo ukuvikela izinto zokusebenza ekugqwaleni ngamakhemikhali.

2. Imboni yokudla neyokwenza imithi

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

Ukumbozwa kwemishini kanye nezimpawu: Ekufakweni kwangaphakathi kanye nezimpawu zemishini yokucubungula ukudla, izinto ze-PTFE ziqinisekisa ukuphepha kokudla kanye nokuqina kwemishini.

3. Inkambu yokuvikela imvelo

Ukwelashwa kwegesi engcolile kanye nokuphathwa kwendle: I-PTFE mesh isetshenziswa kakhulu ekuhlanzeni indle nasekulapheni igesi engcolile, futhi ingahlunga kahle amanzi angcolile kanye negesi engcolile equkethe izinto ezigqwala kakhulu njenge-fluoride ne-chloride.

Ukulawulwa kokungcoliswa kwentuthu yezimboni: Izikhwama zokuhlunga ze-PTFE zisebenza kahle ekuhlungeni intuthu enezinga eliphezulu lokushisa ezimbonini ezifana nokuncibilikisa insimbi, ukukhiqiza usimende kanye nokukhiqiza amandla ashisayo. Ziyakwazi ukumelana namazinga okushisa afika ku-260°C, futhi zibe nokunemba kokuhlunga okuphezulu nokusebenza kahle kokuhlanza.

4. Imboni kawoyela negesi

Uhlelo lokuhlunga uwoyela negesi: I-PTFE mesh ivame ukusetshenziswa ezinhlelweni zokuhlunga ngesikhathi sokukhipha uwoyela negesi, ukucubungula nokuthutha ngenxa yokuphikiswa kwayo okuhle kakhulu kwezinga lokushisa kanye nokuzinza kwamakhemikhali.

5. Imboni yamandla

Amandla enuzi nawomoya: Ekuhlungelweni kwamagesi akhipha imisebe ezikhungweni zamandla enuzi kanye nokuhlunga komoya ezinjinini zomoya, i-PTFE mesh isiphenduke into efanelekile yokuhlunga ngenxa yezakhiwo zayo zikagesi ezinhle kakhulu nokungashi.

6. Inkambu ye-Aerospace

Igesi nesistimu yokuhlunga okuwuketshezi: I-PTFE mesh isetshenziswa kakhulu ezinhlelweni zokuhlunga kwegesi noketshezi ezindizeni nasemkhathini ngenxa yezindawo zayo ezinhle kakhulu zikagesi nokungashi.

7. Ezinye izinhlelo zokusebenza

Impahla kagesi kanye nekagesi: Izakhiwo zokuvala ugesi zezinto ze-PTFE zikwenza kusetshenziswe kabanzi ekufakeni amakhebula, amabhodi esekethe aphrintiwe kanye nezingxenye ezivikelayo zemishini yamandla kagesi aphezulu.

Imishini yezokwelapha: Ukuhlanzeka okuphezulu kwe-PTFE kanye nokumelana namakhemikhali kuyenza ibe impahla ekahle kumishini yezokwelapha njengama-catheter, amavalvu nezixhumi.

I-PTFE mesh idlala indima engenakuthathelwa indawo emikhakheni yezimboni eminingi ngenxa yokumelana kwayo nezinga lokushisa eliphezulu okuhle kakhulu, ukumelana nokugqwala, ukungqubuzana okuphansi kanye nezakhiwo ezingezona izinduku.
