Loko u tirhisa xisirhelelo xo hisa eka ku paka swakudya, layini thireyi yo baka, kutani u funengeta bandi ro fambisa swakudya hi PTFE high-temperature tape , u fanele ku tiva: yi nga hisa ku fikela kwihi? Xana ku ringana nkarhi wo tanihi kwihi? Naswona swi hundzuka rini leswi nga hlayisekangiki?
PTFE yi tiveka hi ku tiya ka yona lokunene ka ku hisa, kambe 'ku tiya ka ku hisa' a swi vuli 'ku nga pimiwi'. Ku tlula swipimelo swa mahiselo swinga vanga ku onhaka ka swilo – naswona eka swiyimo swo biha swinene, humesa musi wa chefu lowu awufanelanga kuva wu hlangana na swakudya.
Aokai PTFE yi phakerile tithepi ta PTFE ta xiyimo xa swakudya ku ringana malembe. Nkongomiso lowu wu hlamusela tindzhawu leti hlayisekeke ta mahiselo, swipimelo swa nkarhi, na swilaveko swa milawu (FDA, EU) eka switirhisiwa swa ku khumbana ka swakudya.
Swipimelo swa Mahiselo – Tizoni Tinharhu ta Nkoka
Xiyenge xa Mahiselo
Nkoka
Tinhlamuselo ta Nkoka
Mahiselo ya Ntirho lowu Yaka emahlweni
≤ 260°C
Ndzilakano wa le henhla. Thepi yi hlayisa matirhelo yo tiya eka vukorhokeri bya nkarhi woleha eka mahiselo lawa. Yi lulamerile eka ti oven to baka, ti heat sealers, na switirhisiwa swo omisa.
Nhlohlorhi ya Mahiselo ya Nkarhi wo Koma
≤ 300°C ya xiyimo xa le henhla
Swi pfumeleriwa ntsena eka nkarhi wo koma swinene (xikombiso, 5-10 wa timinete). Ku tshama nkarhi woleha exikarhi ka 260°C na 300°C swi hatlisisa ku dyuhala ka swilo naswona swi tlakusa makhombo ya vuhlayiseki swinene.
Mahiselo lama yirisiweke
> 327°C
PTFE yisungula ku bola ehenhla ka mahiselo lawa naswona yinga humesa musi wa chefu (kukatsa na perfluoroisobutylene). Ku tirhisa swi yirisiwile hi ku helela. Ku khumbana ka malangavi hi ku kongoma swifanele ku papalatiwa hiku hetiseka.
Xipimelo xa Mahiselo ya le Hansi
≥ -70°C
Thepi yitshama yirikarhi yitirhisiwa eka tindzhawu ta cryogenic kambe yi hundzuka brittle. Ku gombonyoka na ku khumbeka ka michini swifanele ku siveriwaka leswaku kuta papalatiwa ku pandzeka.
Aokai PTFE yi humesa thepi ya food-grade leyi kamberiweke ku tiyisela 260°C leyi yaka emahlweni. Hi tsundzuxa vaxavi lavangana switirhisiwa swa ndzilakano (xikombiso, 270-280°C intermittent) kuva va endla mepe wa mahiselo yale henhla yale ndzhawini naku tekela enhlokweni grade ya thepi yo tiya, leyi nyikaka vukulu byo hisa swinene xikan’we naku onhaka hiku nonoka.
Swipimelo swa Nkarhi – Xana 'Swi Hlayisekile' Yi Fikela Ku Fikela Ku fikela kwihi?
Sweswi, milawu leyikulu ya vuhlayiseki bya matiko ya misava ku katsa na FDA 21 CFR 177.1550 (USA) na Nawu wa EU No 10/2011 a yi vekanga nkarhi wa vuhlanganisi lowu hlayisekeke lowu hlanganeke wa tithepi ta PTFE. Swipimelo swa nkarhi swi vekiwa ngopfu hi mahiselo ya ntirho.
Mahiselo
Nkarhi wo Hlayiseka wa ku Tihlanganisa
Ku anakanya
≤ 260°C
Nkarhi lowu engetelekeke (ku fika eka masiku ya 200 lama kongomisiweke eka tidyondzo tin’wana) .
PTFE yi tshama yi tshamisekile; ku hava ku rhurha loku pimiwaka
260-300°C
Timinetse (hi ntolovelo 5-30 wa timinete, kuya hi mahiselo lawa ya kongomeke) .
Ku dyuhala loku hatlisaka; ku onhaka ka le henhla ka misava ku sungula

A swi bumabumeriwi; tisekoni ku ya eka timinete ti nga ri tingani hi xitalo

Swikombiso leswi tirhaka:
Ku baka xinkwa eka 200°C kuringana 30 wa timinete – swihlayisekile hiku hetiseka, kutirhisiwa hiku phindha-phindha kuringana tinhweti swikahle.
Ku hisa ku pfalela swikhwama swa polyethylene eka 180°C kuringana 1 second – swi hlayisekile, timiliyoni ta swirhendzevutani swa koteka.
Ku basisa heat sealer hiku tsutsuma eka 280°C kuringana 10 wa timinete – swa amukeleka nkarhi wun’wana, kambe kungari siku na siku.
Ku tirhisa PTFE tape tani hi grill liner eka 300°C kuringana 2 wa tiawara – aswi hlayisekanga; thepi yi ta onhaka.
Ku landzelerisa Milawu – Swipimelo swa FDA & EU
FDA 21 CFR 177.1550 – Nawumbisi lowu wu katsa ti resins ta PTFE ku phindha-phindha ku khumbana ka swakudya. A yi boxi nkarhi wo karhi kambe yi lava leswaku xitirhisiwa lexi hetiweke (thepi) xi fanele ku endliwa hi ku landzelela Maendlelo ya kahle ya Vumaki (GMP) naswona a xi fanelanga ku endla leswaku swakudya swi onhiwa.
Nawumbisi wa EU wa 10/2011 – Nawumbisi lowu wu katsa switirhisiwa swa pulasitiki leswi kunguhatiweke ku hlangana na swakudya. PTFE yi xaxametiwile tanihi xiaki lexi pfumeleriweke. Swipimelo swa ku rhurha hi ku angarhela swa tirha (hi ntolovelo ≤10 mg/dm²).
Ndlela leyi ku landzelerisa ku tiyisisiwaka ha yona: Ku landzelerisa ka hambana hi xiyimo xa xikombelo naswona ku fanele ku tiyisisiwa hi ku tirhisa swikambelo swa ku rhurhela . Swikambelo swo tano swi endliwe hi ku ya hi ku hlangana lokukulu swinene ka mahiselo ni nkarhi wa ku khumbana eka swiyimo swa xiviri swa ntirho.

Swiletelo leswi Tirhaka swa Swikombelo swa Ku Tihlanganisa na Swakudya
Swi endla:
✓ Tirhisa thepi ya PTFE endzeni ka 260°C leyi yaka emahlweni ku baka, ku pfalela, na ku hundzisela
✓ Eka swirhendzevutani swo koma swo basisa eka 280-300°C , ringanyeta nkarhi eka 5-10 wa timinete naswona pfumelela ku kufumela
✓ Cinca thepi loko vuandlalo byi hundzuka byo khwaxa, byi cinca muhlovo, kumbe matirhelo yo ka ya nga namarheli ya hunguteka
✓ Hlayisa thepi eka swiyimo leswi tengeke, swo oma hi ku ya hi swipimelo swa muendli
U nga endli tano:
✗ U nga tshuki u tlula 327°C – PTFE ya bola no humesa musi lowu nga na chefu
✗ U nga tshuki u chela langavi ro kongoma eka thepi ya PTFE
✗ U nga tirhisi thepi ya PTFE ehenhla ka 260°C eka ku hlangana ka swakudya nkarhi wo leha (xikombiso, ku baka siku hinkwaro eka 270°C) .
✗ U nga honisi swikombiso leswi voniwaka swa ku dyuhala – ku tshwuka, ku tshoveka, kumbe ku pandzeka ka le henhla
Loko u kanakana: Endla xikambelo xa ku rhurha eka mahiselo ya wena yo biha swinene na nkarhi wa wena, kutani u vulavurisana na muendli wa thepi ku kuma datha yo karhi ya xitirhisiwa.
Hi ku komisa , PTFE high-temperature tape yi hlayisekile eka ku khumbana ka swakudya loko yi tirhisiwa endzeni ka swipimelo swa yona leswi hlamuseriweke: ≤260°C eka ku tirhisiwa loku yaka emahlweni, ≤300°C eka tinhlohlorhi to koma (timinete ntsena) , naswona a yi si tshama yi va ehenhla ka 327°C . Milawu ya FDA na EU ayi veki nkarhi wa misava hinkwayo – nkarhi wa vuhlanganisi lowu hlayisekeke wuya hi mahiselo naswona wufanele ku tiyisisiwa hi swikambelo swa ku rhurha leswi tekelelaka swiyimo swa xiviri.
Eka switirhisiwa swotala swa swakudya leswi tolovelekeke – ku baka, ku pfalela hi kuhisa, na ti non-stick liners – PTFE tape yi kahle endzeni ka ti parameters leti hlayisekeke. Kambe minkarhi hinkwayo pima mahiselo ya xiviri ya le henhla, cinca thepi leyi dyuhaleke hi ku hatlisa, naswona languta matsalwa ya ku landzelela eka switirhisiwa leswi lawuriwaka.
Xana u lava thepi ya PTFE ya giredi ya swakudya eka mahiselo yo karhi na nkarhi wo karhi? Aokai PTFE yi nyika tithepi leti fambisanaka na FDA leti nga na swiyenge swa matirhelo leswi hlayisekeke leswi tsariweke. Tihlanganisi na hina ku kuma maphepha ya datha ya xithekiniki na nseketelo wa xikambelo xa ku rhurha.
Nhundzu leyi yi nyikiwile hi Jiangsu Aokai New Materials Technology Co., Ltd.
Ku kuma vuxokoxoko bya swihlawulekisi, nkongomiso wa xikombelo, na swintshuxo leswi endleriweke layini ya hina ya swikumiwa leswi heleleke, ku katsa na lapi ra mahiselo ya le henhla ya PTFE, tithepi ta mahiselo ya le henhla ya PTFE, mabandhi ya mesh ya PTFE, mabandhi ya muchini wo hlanganisa lama nga riki na swirhabyani, lapi leri funengetiweke hi tlhelo rin’we ra PTFE, mabandhi yo fambisa ya mahiselo ya le henhla na lapi ra fiberglass ya mahiselo ya le henhla , hi kombela u ntshunxeka ku hi tihlanganisa:
