Ukufana kokunamathela kwendwangu yokushisa ephezulu ye-PTFE kunqunywa izici ezine: ukwakheka kokumboza (usayizi wezinhlayiyana 0.15-0.35 μm, i-viscosity, okuqukethwe okuqinile), inqubo yokugqoka kanye ne-sintering (i-blade enamathela ekhethwayo ukuze ifane), ikhwalithi ye-substrate (iphethini yokuluka, ukwelashwa kwangaphambili), nendawo yokukhiqiza (20-25% R <60%). I-Dip + blade inqubo ehlanganisiwe ilinganisa ukungena nokushelela kwendawo.

Ukuhlanzwa nokugcinwa ngendlela efanele kwandisa impilo yendwangu ye-PTFE enezinga eliphezulu lokushisa. Hlanza ngemva kokusetshenziswa nangemuva kokupholisa. Sebenzisa amabhulashi athambile, okokuhlanza okungathathi hlangothi, noma utshwala ukuze uthole amabala. Ungalokothi usebenzise ama-asidi/ama-alkali aqinile, i-bleach, noma ama-metal scrapers. Ukugcoba uwoyela we-silicone njalo kunciphisa ukuguga. Landela le mihlahlandlela ukuze ugweme ukulimala kokumboza.

Indwangu ye-PTFE enezinga eliphezulu lokushisa eliphezulu nendwangu ye-silicone kokubili kusebenzisa indwangu ye-fiberglass njengesisekelo kodwa ihlukile ezintweni zokumboza (i-PTFE resin vs irabha ye-silicone). I-PTFE iphumelela kakhulu ekungabambeni, ukumelana nokugqoka, kanye nokumelana namakhemikhali kufika ku-260°C. Indwangu ye-Silicone inikeza ukuguquguquka okuphakeme, ukufakwa kukagesi, nokumelana nomlilo (kufika ku-230°C). Khetha ngokusekelwe kokubalulekile kwakho.

Indwangu yokushisa ephezulu ye-PTFE (i-PTFE membrane material) iyinketho ephambili yezakhiwo eziqinile. Izinzuzo ezibalulekile: iminyaka engu-30+ yempilo yangaphandle, indawo ezizihlanzelayo (amanzi emvula ageza ukungcola), ukudlulisa ukukhanya okuthambile (6-13%), isilinganiso somlilo Sekilasi A, namandla afana nensimbi angaphansi kuka-1.5 kg/m². Isetshenziswa ezinkundleni zemidlalo, ezikhumulweni zezindiza, nezakhiwo eziyisakhiwo sodumo emhlabeni jikelele.

Indwangu ye-PTFE enezinga eliphezulu lokushisa inikeza ukumelana kwamakhemikhali okukhethekile, imelana nama-asidi aqinile, ama-alkali, izinyibilikisi eziphilayo, namagesi abolayo. Lesi sihloko sichaza ngezinto ezimelana nayo, imikhawulo (izinsimbi ze-alkali ezincibilikisiwe, ama-ejenti anamandla e-fluorinating), nezici ezibalulekile ezifana nezinga lokushisa, ukugxilisa ingqondo, nokucindezeleka komshini.

Ukufakwa kwe-PTFE akugcini nje ngendwangu ye-fiberglass. Lesi sihloko sethula ama-substrates angu-7 ahlukile - i-aramid, i-carbon fibre, i-PBI, insimbi enezimbotshana, i-graphite, i-asbestos (ikhishiwe), kanye nezigcwalisi ze-ceramic - nezici zazo zenqubo, izinzuzo, imikhawulo, kanye nezicelo ezibalulekile.

Indwangu yokushisa ephezulu ye-PTFE ephefumula kakhulu ihlanganisa izakhiwo ezinganamatheli, ukuzinza okushisayo, nokungena komoya. Lesi sihloko sihlola ukusetshenziswa kwayo okubalulekile ekomisweni kwendwangu, ukucubungula ukudla, ukukhiqiza okuyinhlanganisela, izinto zikagesi, ukuthutha umoya, ukuvikelwa kwemvelo, nezinto zokwakha.

Lesi sihloko sichaza ukuthi kungani indwangu ye-fiberglass engena-alkali iyisisekelo esincanyelwayo sendwangu ye-PTFE enezinga lokushisa eliphezulu. Ihlanganisa ukubopha kwamakhemikhali ngama-ejenti ahlanganisayo we-silane kanye nezakhiwo ezibalulekile zomzimba njengokuzinza kwe-thermal, ukuzinza kwe-dimensional, nokumelana nokugqwala - iqinisekisa ukusebenza okuhlala isikhathi eside ezindaweni ezinokhahlo.

Ungayikhetha Kanjani Indwangu Ehlanganisiwe Ye-PTFE Yemiklamo Yezakhiwo?Lapho ukhetha indwangu engcono kakhulu ye-PTFE ezosetshenziselwa ukwakha, kufanele ucabange ngezidingo zephrojekthi, ukuthi isebenza kahle kangakanani, nokuthi izowuthinta kanjani umhlaba. Ungqimba lwe-polytetrafluoroethylene luhle kakhulu ekugcineni izinto ziphephile,

Umhlahlandlela Wokukhetha Indwangu Efanele ye-PTFE Ehlanganisiwe Ye-Fiberglass Yokuvalwa Kwezinga Lokushisa OkuphezuluUkuze ukhethe indwangu ye-fiberglass egcotshwe kahle kakhulu ye-PTFE yokuvala imisebenzi emazingeni okushisa aphezulu, udinga ukwazi izici zayo zokusebenza ezibalulekile, izidingo zebhizinisi lakho, nezinsiza zomphakeli. I-hybrid ekhethekile
