Teflon VS Nylon, He aha ka ʻokoʻa?

ʻO ka hoʻokele ʻana ma ka honua o nā plastics hana kiʻekiʻe e like me Teflon PTFE e hoʻolei iā ʻoe i waena o nā hoʻopaʻapaʻa e like me 'nylon vs teflon' a i ʻole 'delrin vs teflon.' Eia ke alakaʻi wikiwiki e kōkua iā ʻoe e hoʻokele.

ʻO Teflon, ka inoa inoa a mākou e aie ai iā Chemours, kū i ka lehulehu. ʻIke ʻia hoʻi ʻo Polytetrafluoroethylene (PTFE), hōʻike ʻia kēia mea i ka wā e pili ana i ke kūpaʻa kemika a me ka pale ʻana i nā wela kiʻekiʻe. E noʻonoʻo i kahi plastik hiki ʻole ke heheʻe maʻalahi – Haʻaheo ʻo Teflon PTFE i kahi helu heheʻe o 327°C (620°F)! ʻO kēia ka mea i koho nui no nā hana e koi ana i ke kūpaʻa i nā kūlana ahi.

Akā e kali, he mea hou aku. ʻAʻole hui pū ʻo Teflon me nā kemika. Ke kūpaʻa nei ʻo ia, e lilo ia i mea pāʻani ikaika i ka ʻoihana hana, ʻoi loa i ka hana ʻana i nā mea e like me nā gaskets a me nā bearings. E hoʻomanaʻo i kona ikaika dielectric o 60 kV/mm? ʻO ia ke kumu e koho pinepine ai ka insulation uila iā Teflon.

Lohe paha ʻoe i ka poʻe e kamaʻilio e pili ana i ka 'ʻāʻī ʻoʻoleʻa' ʻo Teflon. He paheʻe ia i loko o nā noi kahi e pono ai ka ʻili non-stick, e noʻonoʻo e pili ana i kāu mau pani lāʻau ʻole i ka lumi kuke.

Eia naʻe, ke paʻa i ka hoʻopaʻapaʻa 'teflon vs nylon' a i ʻole 'ptfe vs nylon', e noʻonoʻo i kēia: Pono kēlā me kēia papahana i kona meʻe ponoʻī. ʻAʻole paʻa ʻole ʻo Teflon a paʻa i ka wela, akā kūpono paha ia i nā noi e pono ai ka hoʻopili paʻa? ʻAʻole paha.

ʻO ke koho ʻana i ka plastik kūpono, inā ʻo ia ka hoʻokele ʻana ma o 'nylon vs teflon' a i ʻole e ʻimi ana i ka 'delrin heat resistance,' 'o ia hoʻi ka hoʻolikelike ʻana i nā waiwai kūʻokoʻa o ka mea, e like me ka ikaika tensile a me nā waiwai mechanical, me nā pono o kāu papahana.

ʻO ka ʻoiaʻiʻo, ʻoiai ʻo Teflon PTFE e hoʻonani me kona kūpaʻa wela a me ka inertia kemika, pono nā koi kikoʻī o kāu papahana e alakaʻi i kāu koho waiwai. E pili ana i ka hoʻohālikelike ʻana i nā pono me nā waiwai. E koho maalea, a e hoʻomaikaʻi kāu papahana iā ʻoe!

ʻO Nylon: ʻO ka Paragon o ka ikaika a me ka lōʻihi

ʻO ka hoʻomaka ʻana i kahi huakaʻi ma ka honua o nā plastics e lawe mai iā mākou he alo a he alo me Nylon. He mea paʻa i ka ʻoihana plastics, kona lōʻihi a me ka ikaika tensile kiʻekiʻe, e haʻalulu ana ma waena o 75-120 MPa, e hoʻokiʻekiʻe iā ia i kahi ʻike nui.

Hānau ʻia mai ka manaʻo o Wallace Carothers, ʻaʻole kū wale kēia polymer nylon; e hooho ana. Loaʻa pinepine ʻia i nā ʻāpana mechanical e like me nā gears, bushings, a me nā bearings, hōʻike ʻo ia i kona mau pono mechanical a hoʻopaʻa i ke kūpaʻa me ka haʻaheo. ʻOi aku ka nui o nā kūkākūkā ma waena o 'nylon vs teflon' a i ʻole 'nylon vs delrin,' hana ʻo Nylon i kāna hōʻailona ma nā papahana mīkini a me ka paʻi 3D, mahalo i kona hiki ke pale i ka ʻaʻahu a me ka waimaka.

Eia nō naʻe, loaʻa i kēlā me kēia meʻe kahi quirk. No ka Nylon, ʻo ia kona aloha i ka makū. ʻO ka ʻai ʻana a hiki i ka 1.2% o kona paona i ka wai ke hoʻoluhi ʻia no 24 mau hola, hiki i kēia waiwai kūʻokoʻa ke wili i kona nui a me kona ʻano, e hoʻopilikia ana i kona kūpaʻa nui i nā wahi pulu. No laila, ʻoiai mākou e noʻonoʻo ana i ka 'ʻoi aku ka paʻakikī, nylon a i ʻole teflon,' he mea nui e hoʻomaopopo i nā kaiapuni ʻeleʻele, hiki i ka Nylon ke hōʻike i kahi loli paʻakikī.

Akā naʻe, mai hoʻoluliluli ʻia e nā hoʻopaʻapaʻa 'ptfe vs nylon' me ka ʻole o ka ʻike ʻana i ke ʻano maikaʻi o Nylon. Mai ka textiles a hiki i ka hoʻoheheʻe ʻana, ʻo kona hiki ke hoʻololi i lalo o kona hilinaʻi ma waena o nā ʻoihana like ʻole. I ka hoʻohālikelike ʻana, hiki i nā mea like me 'delrin heat resistance' a i ʻole 'teflon ptfe' chemical stability ke nānā aku i ke kukui ma kekahi mau noi, e hōʻoia ana i kēlā me kēia mea, ʻo Nylon hoʻi, loaʻa kahi wahi e ʻālohilohi ai kona mau mea kūʻokoʻa.

E hoʻomanaʻo, ʻo ke koho ʻana i kahi mea, inā ma waena o ka hoʻopaʻapaʻa 'nylon vs teflon' a i ʻole, e huli ana i ka hoʻohālikelike ʻana i nā koi o ka papahana me nā ikaika waiwai. ʻO Nylon, me kona ikaika ikaika a me ke ʻano pale ʻaʻahu, ʻoiaʻiʻo nō ka lanakila i nā noi he nui, inā ʻike ʻia kona ʻano wai. Hoʻopili maikaʻi i kāu mau koho, a nānā i ka ulu ʻana o kāu mau papahana!

Delrin (POM): ʻO ke kiʻekiʻe o ka ʻoʻoleʻa kiʻekiʻe a me ke kūlana paʻa

E kāʻei kākou i kā mākou ʻimi ʻana me ka luʻu ʻana i ka honua o Delrin, kahi inoa inoa e ulana ana i kāna moʻolelo ma ke kahua o nā thermoplastics, ʻo polyoxymethylene (POM).

Hoʻolaha ʻo Delrin i kāna mau hōʻoia me ka ʻoʻoleʻa koʻikoʻi, ka paʻa ʻana o ka dimensional, a me ka haʻahaʻa haʻahaʻa haʻahaʻa. E noʻonoʻo ʻoe ʻo ia ka mea hilinaʻi, ʻoiai inā makemake ʻoe i kahi mea me ka iwi kuamoʻo no kāu mau ʻāpana mechanical ma muli o kona kūpaʻa kiʻekiʻe a me ka ikaika tensile e hula ana ma waena o 69-79 MPa. ʻO kēia hui ʻana o ka nani kino e lilo ia i mea aloha i nā hiʻohiʻona e koi ana i kahi hui o ka pololei a me ka rigidity.

ʻO ka hoʻohālikelike ʻo 'delrin vs nylon' ke kū pinepine nei, ʻoi aku ka pili o ko lākou pilina me ka wai. E hoʻomoʻa iā Delrin no 24 mau hola a hoʻopaʻa wale ʻo ia i ka 0.25% o ka makū, e lilo ia i mea paʻa i ka wā e pāʻani ai ka hula o ka mea me ka pulu, a me ka uhi ʻana i ka Nylon i nā papahana kahi mea pāʻani nui ka haʻahaʻa.

I nā hiʻohiʻona e koi ana i kahi mea me kahi ʻano paʻa, ʻoi aku hoʻi i nā papahana machining, piʻi ʻo Delrin. ʻO kona pili haʻahaʻa haʻahaʻa a me ka paʻa ʻana i nā ana e kū ai, e kau pinepine ana ma luna o kahi paepae ke kū ka hoʻopaʻapaʻa 'nylon vs delrin'.

Pono e hoʻomaopopo ʻia ʻoiai ʻo ETFE a me PTFE ʻelua no ka ʻohana fluoropolymer, ʻokoʻa kā lākou mau moʻolelo hana. ʻO ka ʻike o kā lākou moʻolelo hana e hoʻomālamalama i kā lākou mau hiʻohiʻona hana a me nā ala noi.

I ka pōkole, ʻoiai ʻo nā kūkākūkā 'delrin vs teflon' a i ʻole 'nylon vs teflon' hiki iā ʻoe ke hoʻololi iā ʻoe, e hoʻomanaʻo: ʻo ia ka mea e pili ana i ka hoʻohālikelike ʻana i nā waiwai kūʻokoʻa o ka mea, e like me ka ikaika mechanical a me ke kūpaʻa ʻana o Delrin e ʻaʻahu, me nā pono o kāu papahana. ʻO ia ke kī i ka wehe ʻana i ka puka i kahi honua kahi e kūleʻa wale ai kāu mau papahana; ʻoi aku lākou. No laila e koho naʻauao, a e ola mau kāu mau papahana!

ʻO Aokai he mea hana ʻoihana o ka PTFE coating material , hāʻawi mākou i nā huahana me Nā lole PTFE, Nā lipine PTFE, Nā kāʻei conveyor PTFE, etc., hele i kā mākou kikowaena huahana e aʻo hou aku, a i ʻole e launa pū me kā mākou hui , hauʻoli nui mākou e hāʻawi iā ʻoe i ke kōkua.
