Buku Lofotokozera Kwambiri la Mawaya Otentha Kwambiri a Teflon

2. Makhalidwe Aakulu ndi Ubwino

Chifukwa chomwe waya wa Teflon umatamandidwira kwambiri chili mu kapangidwe kapadera ka mamolekyu a chinthucho (ma bond amphamvu kwambiri a carbon-fluorine). Makhalidwe ake akuluakulu ndi awa:

(1). Kukana Kwambiri Kutentha Kwambiri:
Kutentha kosiyanasiyana komwe kumagwiritsidwa ntchito: zinthu zachikhalidwe zimatha kugwira ntchito mosalekeza kuyambira -65°C mpaka +200°C (ngakhale +260°C), ndipo kukana kwakanthawi kochepa kumatha kupitirira 300°C. Izi zili kutali kwambiri ndi PVC wamba (-15°C mpaka +105°C) ndi waya wa silicone (-60°C mpaka +200°C).

(2). Kugwira Ntchito Kwabwino Kwambiri Kwamagetsi:
Mphamvu ya dielectric yapamwamba: yokhoza kupirira mphamvu yamagetsi yapamwamba kwambiri popanda kuwonongeka, magwiridwe antchito abwino kwambiri oteteza kutentha.
Kutayika kochepa kwa dielectric komanso kutayika kochepa kwa dielectric: ngakhale pakakhala ma frequency ambiri, kutayika kwa ma signal transmission kumakhala kochepa, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pa data ya ma frequency ambiri komanso kutumiza ma signal a RF.

(3). Kukhazikika Kwambiri kwa Mankhwala:
Sichikhudzidwa ndi ma asidi amphamvu, ma alkali amphamvu, zosungunulira zachilengedwe, kapena mafuta, ndipo sichidzawonongeka ngakhale chikaphikidwa mu aqua regia.

(4). Kapangidwe Kabwino Kwambiri ka Makina:
Kuchepa kwa kukangana: pamwamba pake posalala, sipamata, sipamangika mosavuta, komanso sipamangika ndi dothi.
Kukana bwino kwa lawi: kumakwaniritsa mulingo wa UL94 V-0 woletsa lawi, kumadzizimitsa wekha ukachotsedwa pamoto, komanso kutetezeka kwambiri.
Yoletsa ukalamba komanso yolimbana ndi UV: imasunga kukhazikika kwa magwiridwe antchito kwa nthawi yayitali m'malo ovuta, komanso nthawi yayitali yogwira ntchito.

(5). Ubwino Wina:
Kuchepa kwambiri kwa madzi, pafupifupi palibe.
Si yoopsa komanso yopanda vuto, imagwirizana ndi ziphaso zachipatala ndi zakudya (monga USP Class VI, FDA), yoyenera zida zachipatala ndi chakudya.

3. Mitundu ndi Kapangidwe Kofanana

Waya wa Teflon ukhoza kugawidwa m'magulu osiyanasiyana malinga ndi kapangidwe kake, zipangizo zake, ndi miyezo yake:

(1). Pogwiritsa ntchito zinthu zotetezera kutentha:
PTFE (Polytetrafluoroethylene): yodziwika kwambiri, yokhala ndi magwiridwe antchito ambiri, koma yovuta kuikonza (imafuna kuipitsa).
PFA (Perfluoroalkoxy): magwiridwe antchito ofanana ndi a PTFE, koma amatha kukonzedwa ndi kusungunuka kwa madzi, komwe ndikoyenera kwambiri popanga zotetezera kutentha kwa khoma lopyapyala.
FEP (Fluorinated Ethylene Propylene): mawonekedwe owonekera bwino, kusungunuka bwino.

(2). Malinga ndi kapangidwe kake:
Waya wapakati pa umodzi: kondakitala (yolimba kapena yokhazikika) yokutidwa ndi Teflon insulation. Kapangidwe kokhazikika, komwe kamagwiritsidwa ntchito kwambiri polumikiza mawaya okhazikika.
Waya wotetezedwa ndi ma core ambiri: ma core angapo otetezedwa opindika pamodzi, okulungidwa ndi zojambulazo za aluminiyamu ndi zotchingira mkuwa, ndi chigoba chakunja. Amalimbana bwino ndi EMI, yomwe imagwiritsidwa ntchito potumiza chizindikiro molondola.
Chingwe cha Coaxial: chimakhala ndi kondakitala wapakati, chotenthetsera, choteteza, ndi chivundikiro, chomwe chimagwiritsidwa ntchito potumiza ma RF pafupipafupi.

4. Magawo Akuluakulu Ogwiritsira Ntchito

Chifukwa cha kuphatikiza kwake kwapadera kwa magwiridwe antchito, waya wa Teflon wakhala chisankho chokondedwa pa ntchito zapamwamba komanso zovuta:

(1). Ndege ndi Asilikali: mawaya amkati mwa ndege, maroketi, ma satellite, makina owongolera, makina a radar, ndi zina zotero. Amafuna zipangizo zopepuka, zosatentha kwambiri, komanso zodalirika kwambiri.

(2). Zipangizo Zachipatala: zipangizo zoyezera matenda (CT, MRI), zida zochitira opaleshoni, zida zowunikira, zida zoyeretsera, ndi zina zotero. Zimafuna mankhwala osakhala ndi poizoni, osagwira ntchito ndi mankhwala ophera tizilombo toyambitsa matenda, komanso odalirika kwambiri.

(3). Kupanga Mafakitale:
Malo otentha kwambiri: zingwe za makina ochapira, zotenthetsera, ma uvuni, ma boiler, makina otentha.
Kugwiritsa ntchito pafupipafupi kwambiri: makina otsekera pafupipafupi kwambiri, zida zamagetsi, zoperekera chakudya pa siteshoni yolumikizirana.

(4). Zamagetsi ndi Kulankhulana: zingwe za data zama frequency apamwamba, zingwe za RF coaxial, mawaya amkati a zida zolondola, zida zopangira semiconductor.

(5). Makampani Ogulitsa Magalimoto: mawaya amphamvu kwambiri m'mabatire atsopano a magalimoto, mawaya olumikizira mota, mawaya a masensa. Amafuna kutentha kwambiri komanso kukana mphamvu zambiri.

(6). Zipangizo zapakhomo: mawaya amkati a zida zotenthetsera m'ma aroni, ma uvuni a microwave, ma air fryer, ma uvuni, ndi zina zotero.

5. Kodi Mungasankhe Bwanji Waya wa Teflon?

Posankha, ganizirani zinthu zotsatirazi:

(1). Malo Ogwirira Ntchito:
Kutentha: kudziwa kutentha kwa ntchito kwa nthawi yayitali komanso kutentha komwe kungatheke kwa nthawi yochepa.
Voltage: kudziwa voltage yogwira ntchito ndi kupirira mulingo wa voltage.
Malo okhala ndi mankhwala: kukhudzana ndi mafuta, zosungunulira, ma asidi, ndi maziko.
Malo ogwirira ntchito: kupindika, kusweka, zofunikira pakukoka.

(2). Ziphaso ndi Miyezo:
Sankhani mawaya ogwirizana ndi miyezo yoyenera (UL, CSA, CE, RoHS) malinga ndi misika yotumizira kunja ndi malo ogwiritsira ntchito. Pazida zamankhwala ndi chakudya, ziphaso zoyenera ndizofunikira.

(3). Ubwino wa Waya:
Kondakitala: nthawi zambiri mkuwa wopakidwa m'chitini kapena mkuwa wopanda kanthu. Mkuwa wopakidwa m'chitini umathandiza kukana okosijeni ndi kusungunula. Yang'anani kuwala ndi kulimba kwa chingwe.
Chotetezera kutentha: Waya weniweni wa Teflon umazimitsa wokha moto ukachotsedwa, moto wobiriwira umasonyeza fluorine, umayaka mpaka kukhala machubu osakoka. Mapulasitiki wamba amapitirizabe kuyaka ndi ulusi.
Kusindikiza: komveka bwino, kosatha kutha, kuphatikiza ma specs, miyezo, ziphaso, ndi wopanga.

(4). Zoganizira za Mtengo:
Waya wa Teflon ndi wokwera mtengo kuposa zingwe wamba. Sankhani giredi yoyenera kuti muyeretse magwiridwe antchito ndi mtengo wake.

6. Mapeto

Chifukwa cha kukana kutentha kwambiri, kukana dzimbiri, kutchinjiriza bwino, komanso kukhazikika, waya wa Teflon wakhala chinthu chofunikira kwambiri m'magawo apamwamba a mafakitale ndi ukadaulo. Ngakhale kuti ndi wokwera mtengo, chitetezo chake, kudalirika kwake, komanso nthawi yayitali yogwirira ntchito zimabweretsa phindu losasinthika. Chinsinsi cha yankho labwino kwambiri ndikumvetsetsa bwino zosowa zanu zogwiritsira ntchito ndikulumikizana ndi ogulitsa odalirika.

Zokhudza DZIKO LIMODZI

DZIKO LIMODZIImayang'ana kwambiri pakupereka zipangizo zapamwamba kwambiri zamawaya ndi zingwe, kuphatikizapo zipangizo zotetezera kutentha kwa fluoroplastic, matepi achitsulo, ndi ulusi wothandiza. Zogulitsa zathu zimaphatikizapo zipangizo zotetezera kutentha kwa fluoroplastic zamawaya opirira kutentha kwambiri, komansoUlusi Wotsekereza Madzi, Mylar Tape, Copper Tape, ndi zipangizo zina zazikulu za chingwe. Ndi khalidwe lokhazikika komanso kutumiza kodalirika, timapereka chithandizo champhamvu pakupanga mawaya osatentha kwambiri komanso mawaya osiyanasiyana ndi mawaya owunikira, kuthandiza makasitomala kusunga kudalirika kwa malonda ndi mpikisano m'malo ovuta.
