Ni irihe tandukaniro riri hagati yigitambara cya PTFA na Silicone umwenda wa silicone?

PTFE igitambaro cya PTF na Silicone Silicone ni ibikoresho bibiri bizwi byakoreshejwe munganda butandukanye, ariko bifite ibiranga bitandukanye byabatandukanije. PTFO (PolytetraFluoroathylene) umwenda wambaye, uzwi kandi nka TEFLON WILLANI, itanga imitungo itimukanwa, imitungo itimukanwa, irwanya imiti, no kwihanganira ubushyuhe bwinshi. Kurundi ruhande, umwenda wa silicone utanga guhinduka cyane, kuramba, no kurwanya ikirere. Guhitamo hagati yibi bikoresho biterwa nibisabwa byihariye bisabwe, hamwe na PTFE igaragara mubidukikije bikaze hamwe na porogaramu ndende, mugihe silicone ikundwa kubikorwa byayo na UV. Gusobanukirwa itandukaniro ningirakamaro kugirango uhitemo ibikoresho byiza kumushinga wawe.

Kugereranya ibintu bifatika: PTFE na Silicone yambaye imyenda

Ibigize imiti no gukora

Imyenda ya PTFE yaremye akoresheje urwego rwa polytetraflerorouethlene kugera kubintu shingiro, mubisanzwe fiberglass. Iyi nzira ikubiyemo ubushyuhe bwo hejuru nubuhanga bwihariye kugirango habeho ishyaka rimwe. Igisubizo ni imyenda ifite imitungo idasanzwe idashidikanywaho hamwe nububiko bwimiti.

Imyenda ya silicone, ibinyuranye, ikorwa no gushyira mu bikorwa amazi ya silicone ya silicone ya silicone kuri substrate. Iyi ndwara yo gukiza kugirango ikore hejuru, ibyuma. Inzira yo gukora kuri Silicone yanditswe muri silicone muri rusange iragoye kandi irashobora gukorwa kubushyuhe bwo hasi ugereranije na PTFO.

Kurwanya ubushyuhe n'imitungo itimukanwa

Imwe mu bintu bigaragara ko umwenda wa PTFe wanditse nubushyuhe butangaje. Irashobora kwihanganira ubushyuhe bugera ku 260 ° C (500 ° f) nta gutesha agaciro, bigatuma ari byiza kubisabwa byimisozi miremire mumiterere yinganda. Iyi nyungu zumuriro nimpamvu nyamukuru ituma igitambaro cyapa cyatoranijwe kugirango gikoreshwe ibikoresho byo gutunganya ibiryo nibimera.

Imyenda ya silicone, nubwo nayo irwanya ubushyuhe, muri rusange ifite ubushyuhe bwo hasi. Mubisanzwe bakora neza kugeza kuri 200 ° C (392 ° F). Nyamara, amatara ya silicone akomeza guhinduka no mubushyuhe buke, bushobora kuba bwiza muburyo bumwe aho gushyira mubikorwa byingenzi ari ngombwa.

Kurwanya imiti no gutandukanya

PTFO yatwitse yita amatungo yo kurwanya imiti idasanzwe, asigaye ku mbogamizi hafi yimiti hafi ya yose. Uyu mutungo utuma ntagereranywa mubidukikije kandi kubisabwa birimo imiti ikaze. Imiterere idahwitse ya PTFO iyemeza ko itazanduza cyangwa ngo ikoreshwe nibintu byinshi bihuye nabyo.

Imyenda ya silicone nayo itanga imiti myiza yimiti, cyane cyane kumazi na kama nyinshi. Ariko, barashobora kwibasirwa no gutesha agaciro mugihe bahuye nibicide cyangwa alkalis ikomeye. Muri porogaramu aho impeta za chimique ari premount, umwenda wa PTFE ukunze kugira inkombe.

Imikorere yimikorere: PTFE ipamba ya Velicone umwenda wa silicone

Kuramba no kwambara

PTFO yatembye Erekana iherezo ryiza kandi ryambare. Ubuso bworoshye, budahanitse bwa PTF igabanya guterana amagambo, nayo igabanya kwambara no kurira. Ibi biranga bituma PTFE yatembye umwenda mwiza kubisabwa birimo gukoresha inshuro nyinshi cyangwa ibintu bihoraho, nka convoyeur mumikandara mu nganda.

Imyenda ya silicone, mugihe muri rusange iramba, ntishobora guhuza kwambara PTFE ya PTFE irwanya ibidukikije byinshi. Ariko, bagenda basaba aho guhinduka no guhubuka bisabwa, nkuko gutwikira silicone bidakunze guturika cyangwa gukuramo muri ibi bihe.

Guhinduka no kwimura

Kubyerekeranye no guhinduka, imyenda ya silicone ifite inyungu zisobanutse. Kamere ya elastomenic ya silicone yemerera imiterere irambuye kandi yo kugarura. Iri hugora rituma silicone yanditswe silicone nziza kubisabwa bisaba guhuzagurika muburyo budasanzwe cyangwa aho ibikoresho bigomba guhiga bihutira kutabangamira ubunyangamugayo bwayo.

Imyenda ya PTFE , mugihe idahindagurika nka silicone, iracyatanga pliabulity nziza. Urwego rwo guhinduka rushobora gutandukana bitewe nubunini bwa cotefe hamwe nigitambara cyibanze cyakoreshejwe. Kubisabwa aho impirimbanyi hagati yo kurwanya imiti no guhinduka birakenewe, umwenda wa PTFO wahoze utanga igisubizo cyiza.

Kurwanya ikirere no Guharanira UV

Imyenda ya PTFE hamwe na silicone ya silicone itanga uburyo bwo kurwanya ikirere bwiza, ariko hamwe nibitandukaniro. Imyenda ya PTFE irwanya cyane imirasire ya UV, kubungabunga imitungo yacyo na nyuma yo guhura nizuba. Ibi bituma bihitamo neza kubisabwa hanze aho imikorere yigihe kirekire ari ngombwa.

Imyenda ya Silicone nayo yerekana kandi umutekano mwiza wa UV hamwe no kurwanya ikirere. Bafite akamaro cyane cyane mugukomeza guhinduka no gukumira imyumvire mubidukikije byo hanze. Mubyiciro aho ibintu byoroshye, byoroshye bikenewe kugirango ukoreshe hanze, imyenda ya Silicone yakunze kugira inyungu.

Porogaramu ikwiye: Guhitamo hagati ya PTFE hamwe na silicone yambaye ubusa

Gusaba inganda no gukora

Muburyo bwinganda, umwenda wa PTFA wakunze ufata iyambere kubera kurwanya imiti hejuru yubushyuhe nubushyuhe bwinshi. Bikunze gukoreshwa mubihingwa bitunganya imiti, aho ibintu bitukura nubushyuhe bwo hejuru nibibazo bya buri munsi. PTFE TAVEST TESVEORTS, kurugero, ni byiza konganga gutunganya ibiryo, itanga ubuso budashira birinda ibicuruzwa no koroshya uburyo bwo gusukura.

Imyenda ya silicone yahuye na Niche yabo mumiterere yinganda aho guhinduka ari urufunguzo. Bakunze gukoreshwa muguka kwaguka, guhuza byoroshye, no kwinjiza ibiringiba. Ubushobozi bwa silicone gukomeza imitungo yacyo hakurya yubushyuhe butunganijwe bukwiranye nibisabwa birimo gusiganwa ku maguru.

Ububiko n'Ubwubatsi

Mu rwego rw'ubwubatsi no kubaka, ibikoresho byombi bifite umwanya wabo. Imyenda ya PTFA yakoreshejwe kenshi muburyo bwa Tensile no gusakara. Kuramba, kurwanya ikirere, hamwe no kwisukura imitungo bituma bihitamo neza kugirango habeho inzego zirambye. Imyenda ya Teflon yakoreshejwe muriyi porogaramu irashobora gukomeza kugaragara no gukora imyaka ibarirwa muri za mirongo.

Imyenda ya silicone yakunze gushimishwa muburyo bukabije ninyubako zigihe gito. Guhinduka kwabo no koroshya kwiyongera biba byiza kubikorwa byoherejwe. Byongeye kandi, umuriro wa silicone ufite umupaka urashobora kuba mwiza muri porogaramu zimwe na zimwe zo kubaka aho umutekano wumuriro ari impungenge.

Porogaramu yihariye mu nganda zitandukanye

Guhitamo hagati ya PTFE na Silicone Silicone biba muntambwe muri porogaramu zihariye. Mu nganda za Aerospace, umwenda wa PTFO wakoreshejwe mugukoreshwa muri tank ya lisansi kandi ushishoza kubera impeta zayo nubushyuhe. Umwanya w'ubuvuzi ukoresha umwenda wa PTFE mubikoresho bidahwitse hamwe nibikoresho byo kubaga, kwishyuza bioicompaget hamwe nibidafite inkoni.

Imyenda ya silicone yakiriye porogaramu mu nganda zimodoka zikirere no kunyerera. Ubushobozi bwabo bwo gukomeza guhinduka mu bushyuhe bukabije butuma bikwira muri ibyo bice bikomeye. Muri siporo n'inganda zo kwidagadura, imyenda ya silicone ikoreshwa mu bwato bukaba no hanze n'ibikoresho byo hanze, aho guhuza kuramba no guhinduka bihabwa agaciro gakomeye.

Umwanzuro

Mu gusoza, guhitamo hagati yigitambara cya PTFE hamwe nigitambaro cya silicone biterwa nibisabwa byihariye. Imyenda ya PTFER, hamwe no kurwanya imiti idasanzwe nubushyuhe bwinshi, nibyiza kubidukikije hamwe nibisabwa bisaba imitungo idahwitse. Urundi ruhande rwa Silicone, kurundi ruhande, rutanga ibisobanuro birenze kandi bikora neza mubisabwa bisaba gutandukana no kurwanya ikirere. Ibikoresho byombi bifite imbaraga zabo zidasanzwe, kandi usobanukirwe nitandukaniro ni urufunguzo rwo guhitamo imyenda iboneye kugirango umushinga wawe ukeneye.

Twandikire

Kuburyo bwiza bwa PTFE yimyenda yibisubizo , reba kure AOKE PTFE . Nkumukoreraburiye wa PTFE imyenda ya fiberglass ya fibreglass, dutanga ibicuruzwa byinshi kugirango duhuze ibyo ukeneye. Ubwitange bwacu bwo kwerekana neza ko wakiriye ibikoresho-hejuru na serivisi idasanzwe. Gushakisha uburyo umwenda wa PTFE wanditse ushobora kugirira akamaro umushinga wawe, Twandikire uyumunsi kuri mandy@akptfe.com.
