Hiki ke hana hou ʻia ka PTFE?

ʻO ka PTFE (Polytetrafluoroethylene) plastics he opaque maʻamau, a he pale maikaʻi loa ia i ke kinoea, ka makū, a me ke kū'ē i ka wela.PTFEhōʻike i kahi kūʻē kemika kupaianaha a ʻaʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe ʻike ʻia.Hoʻouka ʻia ia e nā metala alkali hoʻoheheʻe a me ka fluorine i nā wela kiʻekiʻe.He kūpaʻa maikaʻi loa ka PTFE i nā waikawa, alkalis a me nā mea hoʻoheheʻe.He lubricous loa ia, me ka coefficient haʻahaʻa loa o kekahi polymer.He maʻalahi ka hoʻomaʻemaʻe ʻana i ka plasticly inert plastic a loaʻa iā ia ke kūpaʻa mechanical ma lalo o nā kūlana koʻikoʻi.Eia kekahi, ʻo ka PTFE he autoclavable a hiki ʻole ke ahi.

ʻAʻole loaʻa iā PTFE kāna hōʻailona code recycling.Eia naʻe, hiki ke hana hou ʻia ka PTFE i nā huahana ʻē aʻe.Hiki ke hoʻohana hou ʻia ka PTFE no nā koʻokoʻo, ka paipu, ka lipine a me nā mea hou aku.

ʻO ka Polytetrafluoroethylene (PTFE) kahi mea synthetic i hana ʻole ʻia i ka hopena o 1930s.ʻO ia ka wā e hoʻāʻo ai kekahi mea kemika e hoʻomohala i kahi ʻano hou o ka mea hoʻoheheʻe perfluorethylene.Ma mua o ka loaʻa ʻana o kahi chlorofluorocarbon, ua ʻike ka ʻepekema ʻo ka perfluorethylene i hoʻohana ʻia i ke kaʻina hana i hoʻohālikelike ʻia me ka ʻike hao o kāna ipu a polymerized ma lalo o ke kaomi.

Ua puʻunaue ʻia kēia mea hou ma ke ʻano pāʻoihana a ua kapa ʻia ʻo PTFE.Ma hope o kekahi mau makahiki ma hope mai, ua ʻike ʻia ʻo ia ka mea kīhini non-stick mua.

Ma hea kahi e hoʻohana ʻia ai ka PTFE?

Hoʻohana ʻia ia no nā noi kahi e pono ai nā ʻāpana sliding e like me nā bearings plain, gears, a me slide plates.Powdered PTFE i hoʻohana ʻia i nā haku mele pyrotechnic e like me nā oxidizers me nā metala pauka. Hoʻohana ʻia ʻo PTFE i ka radiometry optical.Hoʻohana ʻia nā pepa i hana ʻia mai ka PTFE e like me ke ana ʻana i nā poʻo i nā spectroradiometers a me nā radiometer broadband ma muli o kona hiki ke hoʻopuehu i kahi kukui uila kokoke loa. ʻO ka projectile ʻoi aku ka paʻakikī. Hoʻohana ʻia ʻo ia i nā mea hana hale hana e like me nā ipu, nā mea hoʻouluulu, a me nā paipu.

No ke aha i hoʻohana ʻia ai ka PTFE i nā ʻāpana uila?

Loaʻa i ka PTFE nā waiwai insulating kūʻokoʻa i kūpono no nā mea uila.He non-conductive, ano;kūʻē ia i nā māla uila kiʻekiʻe.He kūpaʻa nō hoʻi ia i ka wela, ka wai, a me ka ʻino kemika.Hoʻohana ʻia ia i ka hana ʻana i nā mea hana hale hana a me nā mea pono e pili ana me ka waika hydrofluoric.

Loaʻa iā PTFE kahi waiwai frictional haʻahaʻa loa.Hana kēia i ka PTFE kūpono no ka hana ʻana i nā ʻāpana e pono ai ke pale aku i ka friction e like me nā bearings a me nā mea hana.

ʻO nā hiʻohiʻona ʻē aʻe o PTFE

• * kahi pale maikaʻi loa i ke kinoea, ka makū a me ka wela
• *He kūpaʻa kemika kupaianaha a hiki ʻole ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe ʻike ʻia
• *hoʻouka ʻia e nā metala alkali hoʻoheheʻe ʻia a me ka fluorine i nā wela kiʻekiʻe
• *He kūpaʻa maikaʻi loa ia i nā waikawa, alkali a me nā solvents
• *lubricous loa
• *hiki ke sterilized e autoclave, kinoea, wela maloʻo a me ka disinfectant kemika
• *Nā hemahema o ka hoʻohana ʻana i ka PTFE

ʻO kekahi o ka hoʻohana maʻamau o PTFE no ka mea kuke.ʻAʻole hiki ke hoʻohana ʻia nā pā PTFE inā ʻike ʻoe i nā ʻōpala a i ʻole nā ​​māwae ma luna.ʻAʻole hiki ke hoʻohana ʻia ma hope o ka pōʻino.Hoʻomaka ia e pōʻino ma hope o ka piʻi ʻana o ka mahana o ka mea kuke i 260˚C a decompose ma luna o 350˚C.Hiki ke make i nā manu a hiki ke hoʻoulu i nā hōʻailona like-flu i ke kanaka.

Nā pilikia i ka hana hou ʻana i ka PTFE

E like me nā mea ʻē aʻe, hoʻemi ka hana hou ʻana i nā waiwai o ka mea kumu.Ma PTFE, maikaʻi ka nui o kāna mau waiwai i hiki ke hiki ma hope o ka hana hou ʻana.Ma kekahi mau haʻawina, hiki i ka 5-10% ka ʻai ʻana ke ʻae i ka mea e hala ma ke ʻano he PTFE maʻemaʻe.ʻO kekahi o nā pilikia nui me ka PTFE i hana hou ʻia ʻaʻole ia e pili no ka hoʻohana lōʻihi.

Akā, e hōʻuluʻulu i nā mea a pau, e loaʻa mau ka PTFE recycled i nā waiwai haʻahaʻa i ka PTFE a ʻaʻole hiki ke kūlike i ka manawa.ʻOi aku ka maikaʻi o ka manaʻo e hiki ke hoʻololi ʻia a ʻoi aku ka haʻahaʻa o ke kumu kūʻai.
