Niba ukoresheje icyuma gishyushya ibicuruzwa bipfunyika, shyira umurongo wo gutekamo, cyangwa utwikire umukandara utanga ibiryo PTFE kaseti yubushyuhe bwo hejuru , ugomba kumenya: ishobora gushyuha gute? Mugihe kingana iki? Kandi ni ryari biba umutekano?
PTFE izwiho kurwanya ubushyuhe buhebuje, ariko 'irwanya ubushyuhe ' ntibisobanura 'unlimited '. Ubushyuhe burenze urugero bushobora gutera kwangirika kwibintu - kandi mubihe bibi cyane, kurekura imyotsi yubumara itagomba na rimwe guhura nibiryo.
Aokai PTFE yatanze kaseti yo mu rwego rwa PTFE kumyaka. Aka gatabo gasobanura ahantu h’ubushyuhe butekanye, igihe ntarengwa, hamwe n’ibisabwa (FDA, EU) kubisabwa kugirango uhuze ibiryo.
Imipaka ntarengwa - Uturere dutatu twingenzi
Icyiciro cy'ubushyuhe |
Agaciro |
Ingingo z'ingenzi |
Gukomeza Ubushyuhe |
≤ 260 ° C. |
Umupaka wibanze. Kaseti ikomeza imikorere ihamye ya serivisi ndende kuri ubu bushyuhe. Birakwiriye gutanura amashyiga, gufunga ubushyuhe, nibikoresho byumye. |
Ubushyuhe bwigihe gito |
≤ 300 ° C. |
Gusa byemewe mugihe gito cyane (urugero, iminota 5-10). Kumara igihe kinini hagati ya 260 ° C na 300 ° C byihutisha gusaza kwibintu kandi bizamura ingaruka z'umutekano ku buryo bugaragara. |
Ubushyuhe bwabujijwe |
> 327 ° C. |
PTFE itangira kubora hejuru yubushyuhe kandi irashobora kurekura imyotsi yuburozi (harimo na parfluoroisobutylene). Gukoresha birabujijwe rwose. Umuriro utaziguye ugomba kwirinda rwose. |
Ubushyuhe buke |
70 -70 ° C. |
Kaseti ikomeza gukoreshwa mubidukikije bya kirogenike ariko bigahinduka. Ingaruka zunamye hamwe nubukanishi bigomba kwirindwa kugirango birinde gucika. |
Aokai PTFE itanga kaseti yo mu rwego rwo hejuru yapimwe kugirango ihangane na 260 ° C ikomeza. Turagira inama abakiriya bafite imipaka ikoreshwa (urugero, 270-280 ° C mugihe kimwe) gukora ikarita yubushyuhe bwikibanza no gutekereza ku cyiciro kinini cya kaseti, gitanga misa nyinshi yubushyuhe no gutinda buhoro.
Igihe ntarengwa - Igihe kingana iki 'Umutekano '?
Kugeza ubu, amabwiriza mpuzamahanga y’umutekano mpuzamahanga arimo FDA 21 CFR 177.1550 (USA) n’amabwiriza y’ubumwe bw’ibihugu by’Uburayi No 10/2011 ntabwo yateganyirije igihe cy’itumanaho ry’umutekano kuri kaseti ya PTFE. Igihe ntarengwa kigenwa cyane cyane nubushyuhe bwo gukora.

Igihe cyongerewe (kugeza ku minsi 200 ivugwa mubushakashatsi bumwe) |
PTFE ikomeza gushikama; nta kwimuka kugaragara |
260-300 ° C. |
Iminota (mubisanzwe iminota 5-30, ukurikije ubushyuhe nyabwo) |
Gusaza vuba; kwangirika hejuru biratangira |
> 300 ° C. |
Ntabwo byemewe; amasegonda kugeza kuminota mike ntarengwa |
Ibyago byo kubora byiyongera vuba |
Ingero zifatika:
Guteka umutsima kuri 200 ° C muminota 30 - umutekano rwose, gukoresha inshuro nyinshi nibyiza.
Shyushya imifuka ya polyethylene kuri 180 ° C kumasegonda 1 - umutekano, amamiriyoni yizunguruka birashoboka.
Kwoza icyuma gishyushya ukoresheje 280 ° C muminota 10 - byemewe rimwe na rimwe, ariko ntabwo buri munsi.
Gukoresha kaseti ya PTFE nka grill liner kuri 300 ° C mumasaha 2 - ntabwo ari umutekano; kaseti izatesha agaciro.
Kubahiriza amabwiriza - Ibipimo bya FDA & EU
FDA 21 CFR 177.1550 - Aya mabwiriza akubiyemo ibisigazwa bya PTFE kugirango basubiremo ibiryo. Ntisobanura igihe ntarengwa ariko isaba ko ingingo yarangiye (kaseti) igomba gukorwa hubahirijwe uburyo bwiza bwo gukora (GMP) kandi ntigomba gutuma ibiryo bisambana.
Amabwiriza y’ubumwe bw’ibihugu by’Uburayi 10/2011 - Aya mabwiriza akubiyemo ibikoresho bya pulasitiki bigamije guhura n’ibiribwa. PTFE yanditse kurutonde nkibintu byemewe. Muri rusange imipaka yo kwimuka ikoreshwa (muri rusange ≤10 mg / dm²).
Uburyo iyubahirizwa ryagenzuwe: Kubahiriza biratandukanye bitewe nibisabwa kandi bigomba kugenzurwa hakoreshejwe ibizamini byimuka . Ibizamini nkibi byateguwe hashingiwe ku guhuza gukabije kwubushyuhe no kumara igihe cyo gukora.

Kora:
Tape Koresha kaseti ya PTFE muri 260 ° C ikomeza muguteka, gufunga, no gutanga
✓ Kubisuku bigufi kuri 280-300 ° C , gabanya igihe kugeza kuminota 5-10 hanyuma wemerere gukonja
✓ Simbuza kaseti mugihe ubuso bwabaye bubi, ibara, cyangwa imikorere idakomeye igabanuka
✓ Bika kaseti ahantu hasukuye, humye kuri buri ruganda
Ntukore:
✗ Ntuzigere urenga 327 ° C - PTFE ibora kandi irekura imyotsi yuburozi
✗ Ntuzigere ukoresha flame itaziguye kuri kaseti ya PTFE
✗ Ntukoreshe kaseti ya PTFE hejuru ya 260 ° C kugirango uhuze ibiryo igihe kirekire (urugero, guteka umunsi wose kuri 270 ° C)
✗ Ntukirengagize ibimenyetso bigaragara byo gusaza - umuhondo, ubukana, cyangwa ibice byo hejuru
Mugihe ushidikanya: Kora ikizamini cyo kwimuka mugihe cyubushyuhe-bubi cyane, cyangwa ubaze uwakoze kaseti kugirango ubone amakuru yihariye.
Muri make , PTFE yubushyuhe bwo hejuru ifite umutekano mukubonana nibiryo iyo ikoreshejwe mugihe cyagenwe: 60260 ° C kugirango ikoreshwe ubudahwema, 00300 ° C kumpinga ngufi (iminota gusa) , kandi ntabwo iri hejuru ya 327 ° C. Amabwiriza ya FDA na EU ntabwo ashyiraho igihe ntarengwa - igihe cyo guhura neza giterwa nubushyuhe kandi bigomba kugenzurwa nibizamini byimuka bigereranya ibihe bifatika.
Kubintu byinshi bikunze gukoreshwa mubiribwa - guteka, gufunga ubushyuhe, hamwe nimirongo idakomeye - kaseti ya PTFE iri mubintu byiza. Ariko buri gihe upime ubushyuhe nyabwo, usimbuze kaseti ishaje vuba, kandi usuzume ibyangombwa byubahirizwa kubisabwa.
Ukeneye kaseti yo mu rwego rwa PTFE kaseti yubushyuhe bwihariye nigihe bimara? Aokai PTFE itanga kaseti ya FDA ifite ibyangombwa bikora neza. Twandikire kumpapuro zamakuru ya tekiniki hamwe ninkunga yikizamini cyo kwimuka.
