Xa ukhetha ilaphu le-fiberglass egqunyiweyo kwizicelo zemizi-mveliso - nokuba kukutywinwa kobushushu, iintambo zokukhulula, ukugqunywa kombane, okanye ukukhuselwa komlilo - amagama amabini avela rhoqo: Ilaphu le-PTFE eliphezulu lobushushu kunye nelaphu le-silicone.
Zombini ziqala ngesiseko esifanayo sokuqina kwe-fiberglass ephezulu, kodwa iingubo zabo ezingaphezulu (i-PTFE resin vs i-rubber ye-silicone) ikhokelela kwiiprofayili zokusebenza ezahlukeneyo. Ukukhetha engalunganga kunokukhokelela ekunxityweni kwangaphambi kwexesha, izinto ezibambekayo, okanye umonakalo wesixhobo.
I-Aokai PTFE yenze zombini iintlobo amashumi eminyaka. Olu ngqamaniso lwecala lubandakanya ukuchasana nokushisa, ukuguquguquka, ukusebenza okungahambi kakuhle, ukunyanzeliswa kokugqoka, ukuzinza kweekhemikhali, ukugquma kombane, kunye nokhuseleko lomlilo - ngoko unokwenza ukhetho olufanelekileyo.

Ukumelana noBuqondo-Apho i-PTFE iKhokela khona
Ilaphu le-PTFE elinobushushu obuphezulu lisebenza ngokuthe chu ukusuka ku -70°C ukuya kuma-260°C kwaye linokumelana nokuya kuthi ga kwi-350°C ixeshana elifutshane. Oku kuyenza ilungele ii-oveni zokubhaka, izitywini zobushushu, kunye neenkqubo zokuhambisa ubushushu obuphezulu.
Ilaphu leSilicone linobushushu obusebenzayo obuphezulu obumalunga nama-230°C. Kusetyenziso oluhlala lungaphezulu kwe-230°C, i-PTFE lolona khetho luthembekileyo.
Impembelelo yelizwe lokwenyani: Kwi-oveni eyomileyo eyi-250 ° C, ilaphu le-silicone linokuqalisa ukujika umbala kwaye liphulukane nokunwebeka kwiinyanga, ngelixa ilaphu le-PTFE lihlala lizinzile iminyaka.

Xa ukhetha i-silicone: Usetyenziso olufuna ukugoba okuqinileyo, ukugoba, okanye ukunyanzeliswa - njengezixhumi eziguquguqukayo ze-duct, i-gaskets yeendawo ezingaqhelekanga, okanye izigqubuthelo ezisuswayo.
I-Aokai PTFE ibonelela ngeentlobo zelaphu zombini. Abathengi bethu bahlala beqala nge-PTFE ngenxa yeenzuzo zayo ezingaguqukiyo, emva koko batshintshele kwi-silicone kuphela xa ukuguquguquka okugqithisileyo okanye ukugquma kombane kuyadingeka. Kuninzi lwezicelo zobushushu kwimizi-mveliso, ukuqina kwe-PTFE kuyalawuleka ngobuchule bofakelo obufanelekileyo (akukho kugotywa kubukhali).
I-PTFE ineyona coefficients isezantsi yokukhuhlana kwayo nayiphi na into eqinileyo (≈0.05-0.1). Phantse akukho nto inamathela kuyo - ngaphandle kwayo. Oku kwenza ilaphu le-PTFE lobushushu obuphezulu libe ngumgangatho wegolide:
Amashiti okubhaka kunye ne-oven liners (ukutya kukhutshwa ngokulula)
Izigqubuthelo zomatshini wokutywina ubushushu (iplastiki enyibilikisiweyo ayibambeleli)
Iibhanti zokuhambisa iimveliso ezincangathi (itshizi, iilekese, izinto ezincamathelayo)
Ilaphu leSilicone linomphezulu okhubekileyo, onerabha. Ithande ukubambisa uthuli kwaye ayinikezeli naluphi na uncedo olubalulekileyo olungasiyo intonga. Ngapha koko, i-silicone inokuba ne-tacky kumaqondo aphezulu kwaye inokubophelela kwizinto ezithile.
UkuNxitywa kunye noKuxhathisa i-Abrasion-PTFE ihlala ixesha elide
Enkosi kwi-PTFE's i-coefficient ephantsi kakhulu yokukhuhlana, ilaphu le-PTFE lizisa ukuxhathisa okugqwesileyo - iindawo ezityibilikayo, iibhleyidi ze-scraper, kunye noqhagamshelwano lwemveliso kubangela umonakalo omncinci kumphezulu.
Ilaphu leSilicone lithambile kwaye linxiba ngokukhawuleza phantsi kwe-abrasion. Kwizicelo zebhanti lokuhambisa ngokukhuhla rhoqo okanye ukudibanisa ukutyibilika, ilaphu le-silicone linokufuna ukutshintshwa kwe-3-5 amaxesha amaninzi ngaphezu kwe-PTFE.

I-Key takeaway: Kwizityalo zekhemikhali, iilabhoratri, okanye nayiphi na imeko enokuvezwa kwe-solvent, i-PTFE iphumelele ngokucacileyo.
Ukugqunywa koMbane kunye nokuNxhathisa koMlilo – Amandla eSilicone
Ukufakwa kombane: Ilaphu lesilicone sisigqubuthelo sombane seprimiyamu esikwaziyo ukumelana nomthwalo wamandla ombane aphezulu. Isetyenziselwa ngokubanzi:
Iibhari zokugquma izigqubu
I-transformer kunye ne-cable insulation
Izigqubuthelo zokhuselo ezinombane ophezulu
Ilaphu le-PTFE libonelela ngeepropati ezikwi-avareji zokugquma kwaye azikhankanywanga kusetyenziso lombane.
Ukuchasana nomlilo: Lo ngamandla amakhulu elaphu le-silicone. Ayinakutsha, ikhusela ubushushu, kwaye iqhele ukwenziwa ibe:
Iingubo zomlilo zokhuseleko lwamashishini
Amakhethini omlilo kunye nezithintelo zomsi
Izikrini zokukhusela i-Welding
Ngelixa ilaphu le-PTFE linqanda ilangatye, ayisiyiyo imathiriyeli ephambili yezicelo zokuthintela umlilo.
Ipropathi eyongezelelweyo - ukuchasana kwemozulu: Ilaphu le-Silicone likwaqhayisa ukuchasana kwemozulu ephezulu kwinkonzo yangaphandle yexesha elide, kunye nobomi benkonzo ukuya kuthi ga kwiminyaka eyi-10 phantsi kokuvezwa kwe-UV. Ilaphu le-PTFE lehla kancinci kancinci ngaphandle (iminyaka engama-30+) kodwa linokuba brittle kubanda kakhulu.

Isishwankathelo , ilaphu le-PTFE lobushushu obuphezulu kunye nelaphu le-silicone linamandla ahlukileyo. I-PTFE igqwesa kwi-non-stick, ukumelana nobushushu (260 ° C), ukumelana nokunxiba, kunye nokungangeni kweekhemikhali - okwenza kube lolona khetho luphezulu lokulungiswa kokutya, ukutywinwa kobushushu, kunye neemeko zemichiza. Ilaphu le-Silicone likhanya ngokuguquguquka, ukugquma kombane, kunye nokukhuselwa komlilo - ilungele ukugubungela umbane, iingubo zomlilo, kunye nokudibanisa okuguquguqukayo.
Kuyo yonke indawo 'ingcono' - ukhetho olulungileyo luxhomekeke kubushushu bakho bokusebenza, ukuvezwa kweekhemikhali, iimfuno zoomatshini, kunye nohlahlo lwabiwo-mali.
