ʻO ka hoʻomohala ʻana o Polytetrafluoroethylene (PTFE) - mai kahi huahana niche i hoʻohana wale ʻia i nā noi waiwai kiʻekiʻe a hiki i kahi koi nui.
Eia nō naʻe, i loko o nā makahiki he ʻelua i hala iho nei, ua ʻike ʻia ka hoʻohana ʻana o PTFE i kahi nui koʻikoʻi, e ʻae iā ia e lilo i mea kūʻai aku ma mua o 200 ʻoihana, mea kūʻai a me nā noi olakino.A ʻoiai ʻo nā lau, nā koʻokoʻo, nā uhi a me nā ʻāpana ke kihi i ka hapa nui o ka mākeke no nā huahana PTFE, ʻo ka PTFE tube a me ka hose PTFE ke kū mai nei i wahi ulu nui.
Nā noi paipu PTFE
Ka hoohana ana oPTFE paipuua laha ma nā ʻano noi like ʻole me ka automotive, kemika, uila a me ka lāʻau lapaʻau.Hōʻike ka Papa 1 i nā waiwai koʻikoʻi e hōʻike ana i ka versatility o ka paipu PTFE, ʻoiai ke hōʻike nei ka Fig 1 i kona hoʻohana ʻana ma nā ʻano āpau.
Ma nā noi kaʻa, hiki i ka PTFE ke kū i nā mahana ma mua o 250 ° C e lilo ia i moho kūpono no ka hoʻololi ʻana i ka wai wela.
Ma nā noi lapaʻau,PTFE paipukoi nui ʻia ma muli o kona lubricity a me ka inertness kemika.Hiki ke hoʻokomo ʻia nā catheters e hoʻohana ana i ka paipu PTFE i loko o ke kino kanaka me ka makaʻu ʻole i ka hopena a i ʻole abrasion me nā ʻāpana kino.
Ma nā noi kemika - me nā laboratories - ʻo PTFE kahi pani kūpono no ke aniani ma muli o kona inertness a me ka lōʻihi.
Ma nā noi uila, nā waiwai dielectric maikaʻi loa o ka PTFE puʻupaʻa i kūpono no ka hoʻopili ʻana i nā kaula uila kiʻekiʻe.
Nā ʻano o ka paipu PTFE
Ma muli o ka noi, ua māhele ʻia ka paipu PTFE i ʻekolu mau ʻāpana ākea - kēlā me kēia i wehewehe ʻia e ke anawaena o ka paipu a me ka mānoanoa o ka pā (e nānā i ka Papa 2).
ʻOiai i loko o nā ʻāpana, hāʻawi ka pahu PTFE iā ia iho i nā ʻano like ʻole, e ʻae ana kēlā me kēia i kahi noi ʻokoʻa (e nānā i ka Papa 3):
ʻO ka paipu PTFE i ka mākeke mea lapaʻau
Ma keʻano laulā, hoʻohana ʻia ka paipu spaghetti anawaena liʻiliʻi i nā lāʻau lapaʻau.ʻO ka hoʻohana ʻana i ka PTFE ma kēia wahi e pili ana i ʻelua mau waiwai nui: lubricity a me biocompatibility.Hōʻike nā Fluoropolymers i ka lubricity maikaʻi loa e hoʻohālikelike ʻia me nā plastics ʻē aʻe.ʻO PTFE ka polymer lubricious loa i loaʻa, me ka coefficient o friction o 0.1, a ukali ʻia e ka fluorinated ethylene propylene (FEP), me 0.2.Hōʻike kēia mau polymers ʻelua i ka hapa nui o nā paipu fluoropolymer a pau i hoʻohana ʻia i nā lāʻau lapaʻau.
ʻO ka biocompatibility o kekahi polymer i hoʻohana ʻia i kahi lāʻau lapaʻau kahi hopohopo maopopo.ʻOi aku ka PTFE ma kēia wahi a he moʻolelo lōʻihi kona o ka hoʻohana ʻana i vivo.Pono nā fluoropolymers lāʻau lapaʻau e hoʻokō i nā koi hoʻāʻo USP Class VI a me ISO 10993.ʻOiaʻiʻo, ʻo ka hana maʻemaʻe kekahi mea nui.
I nā makahiki he 18 i hala iho nei, hoʻomau mau ʻo Besteflon i ka hana ʻana o PTFE Tubes a me PTFE hose.Ma keʻano he mau paionia ma kahi o ka fluoroplastics manufacturing, ke alualu nei mākou i ka maikaʻi maikaʻi loa a me ka lawelawe ma hope o ke kūʻai aku.
