Hoʻohui Kimia a me ka hana hana
Hana ʻia ka lole i uhi ʻia ʻo PTFE ma ka hoʻopili ʻana i kahi papa o polytetrafluoroethylene i kahi mea kumu, ʻo ka fiberglass maʻamau. ʻO kēia kaʻina hana e pili ana i nā wela kiʻekiʻe a me nā ʻenehana kūikawā e hōʻoia i ka uhi ʻokoʻa. ʻO ka hopena he lole me nā waiwai non-stick kūikawā a me ka inertness kemika.
ʻO ka lole i uhi ʻia ʻo Silicone, ʻo ia hoʻi, ua hana ʻia ma ka hoʻopili ʻana i ka lāʻau silicone wai i kahi substrate. Hoʻomaʻamaʻa kēia uhi ʻana e hana i kahi ʻili maʻalahi, like me ka ʻili. ʻO ke kaʻina hana no nā lole i uhi ʻia silicone he mea liʻiliʻi ka paʻakikī a hiki ke hana ʻia ma nā haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me ka uhi PTFE.
Kūleʻa wela a me nā waiwai wela
ʻO kekahi o nā hiʻohiʻona kūʻokoʻa o ka lole i uhi ʻia ʻo PTFE ʻo ia kona kūpaʻa wela kupaianaha. Hiki iā ia ke pale i nā mahana a hiki i ka 260 ° C (500 ° F) me ka ʻole o ka hoʻohaʻahaʻa ʻana, i mea kūpono no nā noi wela kiʻekiʻe ma nā ʻoihana ʻoihana. ʻO kēia kūpaʻa wela ke kumu nui i koho pinepine ʻia ai ka lole i uhi ʻia ʻo PTFE no ka hoʻohana ʻana i nā lako hana meaʻai a me nā mea kanu kemika.
ʻO nā lole i uhi ʻia ʻo Silicone, ʻoiai ʻaʻohe wela, ʻoi aku ka haʻahaʻa o ka paepae wela. Hana maikaʻi lākou a hiki i ka 200°C (392°F). Eia nō naʻe, mālama ka pale silicone i ko lākou maʻalahi a hiki i nā haʻahaʻa haʻahaʻa, hiki ke kūpono i kekahi mau noi kahi mea koʻikoʻi ka pliability.
Palekana Kemika a me ka Inertness
Ke hoʻokiʻekiʻe nei ka lole i uhi ʻia ʻo PTFE i ke kūʻokoʻa kemika, ke koena inert i nā mea kemika a me nā mea hoʻoheheʻe. He waiwai nui kēia waiwai i loko o nā kaiapuni corrosive a no nā noi e pili ana i nā kemika koʻikoʻi. ʻO ke ʻano non-reactive o PTFE e hōʻoiaʻiʻo ʻaʻole ia e hoʻohaumia a hoʻopilikia ʻia e ka hapa nui o nā mea i hoʻopili ʻia.
Hāʻawi nā lole i uhi ʻia ʻo Silicone i ke kūpaʻa kemika maikaʻi, ʻoi aku ka nui o ka wai a me nā mea hoʻoheheʻe kūlohelohe. Eia nō naʻe, hiki paha iā lākou ke hoʻohaʻahaʻa i ka wā e ʻike ʻia ai i kekahi mau waikawa a i ʻole nā alkali ikaika. I nā noi kahi inertness kemika ka mea nui, PTFE uhi lole pinepine i ka lihi.
Nā hiʻohiʻona hana: PTFE i uhi ʻia i ka lole vs. Silicone i uhi ʻia
ʻO ke kūpaʻa a me ka pale ʻana i ka lole
Hōʻike ka lole i uhi ʻia ʻo PTFE i ke kūpaʻa maikaʻi a me ke kūpaʻa. ʻO ka maʻemaʻe a me ka ʻole o ka ʻili o ka PTFE e hōʻemi i ka friction, ka mea e hōʻemi i ka ʻaʻahu a me ka waimaka. ʻO kēia hiʻohiʻona e hana i ka lole i uhi ʻia ʻo PTFE i kahi koho maikaʻi loa no nā noi e pili ana i ka hoʻohana pinepine ʻana a i ʻole ke kahe mau mea, e like me nā kāʻei conveyor i nā ʻoihana ʻoihana.
ʻO nā lole i uhi ʻia ʻo Silicone, ʻoiai ʻo ka lōʻihi ka lōʻihi, ʻaʻole i kūlike me ke kūpaʻa ʻaʻahu o PTFE i nā kaiapuni kiʻekiʻe. Eia nō naʻe, ʻoi aku lākou i nā noi kahi e koi ʻia ai ka maʻalahi a me ka hoʻololi hou ʻana, no ka mea, ʻoi aku ka liʻiliʻi o ka uhi silicone i ka haki ʻana a i ʻole ka ʻili ʻana ma lalo o kēia mau kūlana.
Hoʻololi a me ka Elasticity
Ma ke ʻano o ka maʻalahi, ʻoi aku ka maikaʻi o nā lole i uhi ʻia silicone. ʻO ke ʻano elastomeric o ka silicone e hiki ai ke hoʻolōʻihi maikaʻi a me nā waiwai hoʻihoʻi. ʻO kēia maʻalahi e hana i nā lole i uhi ʻia silicone i kūpono no nā noi e koi ana i ka conformability i nā ʻano like ʻole a i ʻole kahi e pono ai ka mea e hoʻololi pinepine me ka ʻole o ka hoʻohālikelike ʻana i kona kūpaʻa.
ʻO ka lole i uhi ʻia ʻo PTFE , ʻoiai ʻaʻole maʻalahi e like me ke silicone, hāʻawi mau i ka pliability maikaʻi. Hiki ke ʻokoʻa ke kiʻekiʻe o ka maʻalahi ma muli o ka mānoanoa o ka uhi PTFE a me ka lole kumu i hoʻohana ʻia. No nā noi kahi e pono ai ke kaulike ma waena o ke kūpaʻa kemika a me ka maʻalahi, hāʻawi pinepine ka lole uhi PTFE i kahi hopena maikaʻi loa.
Kūleʻa Ka Lewa a me ka Paʻa UV
Hāʻawi ka PTFE a me nā lole i uhi ʻia ʻo silicone i ke kūpaʻa maikaʻi loa, akā me kekahi mau ʻokoʻa. ʻO ka lole i uhi ʻia ʻo PTFE ke kūpaʻa loa i ka radiation UV, e mālama ana i kāna mau waiwai ma hope o ka lōʻihi o ka ʻike ʻana i ka lā. ʻO kēia ke koho maikaʻi loa no nā noi waho kahi mea koʻikoʻi ka hana lōʻihi.
Hōʻike pū ʻia nā lole i uhi ʻia ʻo Silicone i ke kūpaʻa UV maikaʻi a me ke kū ʻana i ka wā. He kūpono loa lākou i ka mālama ʻana i ka maʻalahi a me ka pale ʻana i ka brittleness i nā kaiapuni waho. I nā noi kahi e pono ai kahi mea palupalu, pliable no ka hoʻohana lōʻihi ʻana i waho, ʻoi aku ka maikaʻi o nā lole uhi silicone.
Pono ka noi: Ke koho ʻana ma waena o ka PTFE a me nā lole i uhi ʻia ʻo Silicone
Noi Hana Hana
Ma nā ʻoihana ʻenehana, lawe pinepine ʻia ka lole i uhi ʻia ʻo PTFE ma muli o kona kūpaʻa kemika kiʻekiʻe a me ka hoʻomanawanui kiʻekiʻe. Hoʻohana maʻamau ia i nā mea kanu hoʻoponopono kemika, kahi e pilikia ai nā mea ʻino a me nā mahana kiʻekiʻe. ʻO nā kāʻei conveyor i uhi ʻia ʻo PTFE, no ka laʻana, he kūpono ia no nā ʻoihana hoʻomaʻemaʻe meaʻai, e hāʻawi ana i kahi ʻili non-stick e pale ai i ka hoʻopili ʻana o ka huahana a maʻalahi i nā kaʻina hoʻomaʻemaʻe.
Loaʻa nā lole i uhi ʻia ʻo Silicone i kā lākou niche i nā noi ʻoihana kahi mea nui o ka maʻalahi. Hoʻohana pinepine ʻia lākou i nā hui hoʻonui, nā mea hoʻopili maʻalahi, a me nā pākeke insulation. ʻO ka hiki o ke silicone ke mālama i kona mau waiwai ma kahi ākea ākea e kūpono ia no nā noi e pili ana i ka holo kaʻa wela.
Hoʻohana no ke kūkulu hale
Ma ke ʻano o ka hoʻolālā a me ke kūkulu ʻana, aia nā mea ʻelua i ko lākou wahi. Hoʻohana pinepine ʻia ka lole uhi PTFE i nā hale tensile a me nā noi hale. ʻO kona lōʻihi, ka pale ʻana i ka wā, a me nā waiwai hoʻomaʻemaʻe ponoʻī he koho maikaʻi loa ia no nā hale lōʻihi o waho. ʻO ka lole i uhi ʻia ʻo Teflon i hoʻohana ʻia i kēia mau noi hiki ke mālama i kona helehelena a me kāna hana no nā makahiki he ʻumi.
ʻO nā lole i uhi ʻia ʻo Silicone i makemake pinepine ʻia no nā hale inflatable a me nā hale no ka manawa pōkole. ʻO kā lākou maʻalahi a me ka maʻalahi o ka hoʻopili ʻana i mea kūpono no nā hale hiki ke hoʻoili ʻia. Eia kekahi, hiki ke hoʻohana maikaʻi ʻia nā waiwai pale ahi o ka silicone i kekahi mau noi hale kahi mea e hopohopo nui ai ka palekana ahi.
Nā noi kūikawā ma nā ʻoihana like ʻole
ʻO ke koho ma waena o ka PTFE a me nā lole i uhi ʻia silicone e lilo i nuanced i nā noi kūikawā. I ka ʻoihana aerospace, hoʻohana pinepine ʻia ka lole i uhi ʻia ʻo PTFE no nā liner pahu wahie a me ka insulation ma muli o kona inertness kemika a me ka pale wela. Hoʻohana ka lāʻau lapaʻau i ka lole i uhi ʻia i ka PTFE i nā mea implantable a me nā mea hana ʻoki, e hoʻohana ana i kona biocompatibility a me nā waiwai non-stick.
Loaʻa nā lole i uhi ʻia ʻo Silicone i nā noi i ka ʻoihana kaʻa no nā ʻeke air a me nā uhi pale. ʻO ko lākou hiki ke hoʻomau i ka maʻalahi i nā mahana wela e kūpono iā lākou no kēia mau mea koʻikoʻi palekana. I loko o ka ʻoihana haʻuki a me ka leʻaleʻa, hoʻohana ʻia nā lole i uhi ʻia silicone i nā waʻa inflatable a me nā lako waho, kahi i manaʻo nui ʻia ai kā lākou hui ʻana o ka lōʻihi a me ka maʻalahi.
Ka hopena
I ka hopena, ʻo ka koho ma waena o ka lole i uhi ʻia ʻo PTFE a me ka lole i uhi ʻia e silicone e pili ana i nā koi kikoʻī o kāu noi. ʻO ka lole i uhi ʻia ʻo PTFE, me kona kūpaʻa kemika kūʻokoʻa a me ka hoʻomanawanui kiʻekiʻe, he kūpono ia no nā kaiapuni ʻoihana a me nā noi e koi ana i nā waiwai non-stick. ʻO ka lole i uhi ʻia ʻo Silicone, ma ka ʻaoʻao ʻē aʻe, hāʻawi i ka maʻalahi a hana maikaʻi i nā noi e koi ana i ka elasticity a me ka pale ʻana i ka wā. Loaʻa i nā mea ʻelua ko lākou ikaika kūʻokoʻa, a ʻo ka hoʻomaopopo ʻana i kēia mau ʻokoʻa ke kī i ke koho ʻana i ka lole kūpono no nā pono o kāu papahana.
Kāhea iā mā˚ou
No ka mea kiʻekiʻe kiʻekiʻe PTFE uhi uhi ʻoluʻolu, e nana hou aku Aokai PTFE . Ma keʻano he mea hana nui o ka PTFE coated fiberglass fabric, hāʻawi mākou i kahi ākea o nā huahana e hoʻokō i kāu mau pono kiko'ī. ʻO kā mākou kūpaʻa i ka maikaʻi e hōʻoia e loaʻa iā ʻoe nā mea kiʻekiʻe a me ka lawelawe kūikawā.
