ʻO ka PTFE kiʻekiʻe-mehana lole (PTFE-coated fiberglass) he maikaʻi wale nō e like me nā mea maka i hoʻohana ʻia e hana ai. ʻElua mea nui: ka PTFE resin/emulsion (ka uhi) a me ka fiberglass substrate (ka hoʻoikaika ʻana). ʻO nā mea haumia i loko o kēlā me kēia - nā ion metala, nā polymers haʻahaʻa-molecular-weight, nā mea hoʻokaʻawale nui, a i ʻole alkali oxides - hiki ke kumu i ka hāʻule mua ʻole: melemele, māhā, nalowale o ka lāʻau ʻole, delamination, a i ʻole ka insulation breakdown.
Hoʻohana ʻo Aokai PTFE i nā mea maka maʻemaʻe kiʻekiʻe a me ke kaʻina hana koʻikoʻi. Hōʻike kēia alakaʻi i ka hopena o ka maʻemaʻe i kēlā me kēia ʻano hana a me ke kumu e pono ai no nā noi koi.
PTFE Raw Material Purity – He aha nā haumia i loaʻa?
ʻO nā haumia maʻamau i loko o ka PTFE he:
ʻO nā monomers i hana ʻole ʻia a me nā polymers haʻahaʻa-molecular-kaumaha
Nā mea hoʻomaka a me nā mea hoʻopuehu (e laʻa, PFOA)
Nā iona metala (hao, keleawe, sodium)
Hoʻoponopono i nā mea kōkua a me nā huahana
ʻO ka maʻemaʻe kiʻekiʻe e hiki ai i ka mea hana ke hāʻawi i ka hana kokoke i nā kikoʻī kūpono.
1. ʻO ke kūpaʻa wela a me ke kūpaʻa wela
ʻO nā ion metala (hao, keleawe, sodium) hana ma ke ʻano he catalysts ikaika no ka PTFE thermal degradation . Ma lalo o ka lawelawe lōʻihi ma luna o 260 ° C, ʻo ka ʻike ʻana i nā mea haumia metala e hoʻolalelale i ka haki ʻana o ke kaulahao molekala, e hoʻoulu ai i ka embrittlement a me ka haki ʻana. ʻO ka PTFE maʻemaʻe kiʻekiʻe e hōʻike ana i kahi mahana decomposition thermal kiʻekiʻe, mau keʻokeʻo maʻemaʻe, a pale maikaʻi i ka melemele.
2. Ka hana non-stick a me ka maikaʻi o ka ili
ʻO nā polymers haʻahaʻa-molecular-kaumaha a me nā huahana ʻaila e neʻe i ka ʻili o ka uhi ʻana i ka wā o ka sintering wela kiʻekiʻe, e hana ana i nā precipitates.
Nā waiwai lāʻau ʻole i hōʻino ʻia: Lilo ka ʻili a pili i nā mea i hana ʻia (nā meaʻai, nā lipine adhesive).
Hiki ke hoʻohaumia ʻia: Ma nā papa meaʻai a me nā noi lapaʻau, hiki i ka neʻe ʻana ke hoʻohaumia i nā huahana a hāʻule i nā kūlana maʻemaʻe. ʻO ka maʻemaʻe kahi hōʻailona kumu no nā lole PTFE pili i ka meaʻai.
3. Ka hana hoʻoheheʻe uila
ʻO nā iona haumia (metal ions, halogen ions) e lawelawe ma ke ʻano he lawe ukana, e hōʻemi nui ana i ka resistivity a me ka haʻihaʻi uila. No nā noi hoʻonaʻauao kiʻekiʻe (e laʻa, nā gaskets insulating uila), he mea koʻikoʻi ka maʻemaʻe maka. ʻO nā pores i hana ʻia e nā haumia hiki ke alakaʻi i ka hoʻokuʻu hapa.
4. Ke kū'ē a me ka compactness
Holo nā mea ʻeleʻele hiki ke hoʻoheheʻe ʻia i ka media kemika, e waiho ana i nā micro-pores i loko o ka uhi. Hāʻawi kēia mau hemahema i ke kinoea kino a me ka wai e komo a hoʻopau i ka substrate fiberglass, e hōʻemi ana i ka hana pale o ka lole.
ʻO ka maʻemaʻe o ka substrate fiberglass - nā mea pili i ka maʻiʻo alkali
ʻAʻole ʻo ka fiberglass ka silika dioxide maʻemaʻe. ʻO kāna mea hana kemika e wehewehe i ka pale wela, ka ikaika mechanical, a me ka hoʻopaʻa ʻana me PTFE.
1. ʻO ka mea hoʻoheheʻe metala alkali - ke kumu hoʻoholo
ʻAno aniani
Na₂O + K₂O maʻiʻo
Nā hiʻohiʻona
aniani uila (ʻole alkali)
<0.8%
ʻO ka maʻemaʻe kiʻekiʻe, ka insulation uila maikaʻi loa, ka nalowale o ka ikaika i nā mahana kiʻekiʻe - maʻamau no ka lole PTFE
aniani-alkali aniani
~12%
ʻO ke kumu kūʻai haʻahaʻa, ke kū ʻole i ka wela, hāʻule ka ikaika i nā wela kiʻekiʻe
aniani-alkali kiʻekiʻe
>15%
Hoʻohaʻahaʻa wikiwiki ma lalo o ka wela; ʻO nā ion alkali e hoʻopau i ka decomposition PTFE
Ma ke kiʻekiʻe wela, alkali metala ions mai ka haʻahaʻa-maʻemaʻe aniani 'aʻole wale hoʻonāwaliwali i ka lole pono'ī akā no ka catalyze degradation o ka PTFE uhi , accelerating holoʻokoʻa hemahema. Hoʻohui hou, ʻo ke aniani medium/high-alkali e hoʻopaʻa i ka makū, e hāʻule loa ka pale ʻana i ka insulation.
2. Nā mea hoʻopaʻa paʻa - nā mea haumia ʻē aʻe
Hoʻohana ʻia nā mea hoʻohālikelike (starch, PVA, ʻaila) i ka wā ulana fiberglass e pale i nā fiber. Inā ʻaʻole hoʻopau loa ʻia ma mua o ka uhi ʻana o PTFE, e hoʻoneʻe ʻia nā koena organika i carbonize, decompose, a me ke kinoea i ka wā sintering ma kahi o 400°C.
Nā hemahema o ka ʻili: ʻeleʻele melemele, ʻeleʻele, ʻeleʻele – ʻaʻole hiki ke nānā ʻia nā huahana.
Nawaliwali ka pilina pili: Ho'opa'a nā koena kalapona i ke kino a me ka heleuma kino ma waena o ka PTFE a me ka fiberglass, e ho'oulu ai i ka delamination, blistering, a me ka peeling i ka wā lawelawe.
3. Ke kū'ē i ka luhi luhi
ʻO nā ʻōhū ea micro a me nā haumia crystalline i loko o nā filament fiberglass e hoʻemi i ka ikaika tensile o nā fibers pākahi. Ma lalo o ka piʻi pinepine ʻana, lilo kēia mau hemahema i mau wahi koʻikoʻi koʻikoʻi, e hoʻomaka ana i ka haki ʻana o ka fiber a hōʻemi nui i ka loli a me ke ola.
Hōʻuluʻulu manaʻo - Hoʻonohonoho ka Maʻemaʻe i ka Hale Hana
Hoʻomoe ka maʻemaʻe o ka waiwai i ka hana nui o nā lole wela kiʻekiʻe PTFE:
Hoʻoholo ka PTFE maʻemaʻe kiʻekiʻe : ka wela o ka lawelawe kiʻekiʻe (260 ° C +), ka paʻa ʻole o ka lāʻau lōʻihi, ka insulation uila hilinaʻi, a me ka mālama ʻana i ka meaʻai.
ʻO ka fiberglass alkali-ʻole maʻemaʻe kiʻekiʻe (E-aniani, Na₂O <0.8%) a me ka hoʻoneʻe ʻana i ke ʻano nui: ikaika substrate i nā wela kiʻekiʻe, paʻa ke ʻano, a me ka hoʻopili ʻana i ka uhi paʻa me ka ʻole o ka delamination.
ʻAʻole lawa ka maʻemaʻe i kekahi loulou e alakaʻi i ka hāʻule mua - melemele, delamination, insulation breakdown, a me ka nalowale o ka non-stick - ʻoi loa ma lalo o nā kūlana paʻakikī: lōʻihi ka wela kiʻekiʻe, ka uila kiʻekiʻe, a i ʻole nā koi hoʻomaʻemaʻe koʻikoʻi.
Aokai PTFE kumu wale kiʻekiʻe-maʻemaʻe PTFE emulsion (haʻahaʻa metala Ion, haʻahaʻa oligomer) a me E-aniani fiberglass lole (alkali-noa, piha wela-hoʻomaʻemaʻe). Hāʻawi mākou i nā palapala hōʻoia waiwai a hiki ke kākoʻo i nā noi meaʻai a me nā noi insulation kiʻekiʻe. E kelepona iā mākou no nā kikoʻī kikoʻī.
Inā makemake ʻoe e aʻo hou aʻe e pili ana i nā kikoʻī kikoʻī, nā hiʻohiʻona noi a me nā hoʻoponopono i hoʻoponopono ʻia no kā mākou huahana piha piha, me nā lole PTFE kiʻekiʻe-mehana, PTFE kiʻekiʻe-mehana lipine, PTFE mesh kāʻei, seamless hoʻopaʻa mīkini kāʻei, hoʻokahi ʻaoʻao PTFE lole, kiʻekiʻe-mehana pale conveyor kāʻei a me ka wela kiʻekiʻe, eʻoluʻolu e leka uila iā mākou: fiberglass fabrics.
