Nā ʻano like ʻole o ka PTFE Tubes a me kāna mau hoʻohana

ʻO ka PTFE ka plastic lōʻihi loa i ʻike ʻia i kēia manawa.Hoʻohana nui ʻia ia i nā ʻoihana like ʻole me nā kaiapuni paʻakikī.Ma muli o kāna hana maikaʻi loa, ua lilo ia i mea waiwai nui i nā huahana plastik (Ua kapa ʻia ʻo Polytetrafluoroethylene).No laila, ʻoi aku ka nui o nā mea hana e hana ana i ia mau huahana.Hiki ke hana ʻia ka PTFE i nā ʻano huahana he nui, e like me nā paipu, nā koʻokoʻo, nā papa, nā gaskets, nā kiʻiʻoniʻoni, a me nā mea ʻē aʻe, i hoʻohana ʻia ma nā ʻano ʻano.

Nā ʻano like ʻole o ka PTFE Tubes a me kāna mau hoʻohana

He aha ka PTFE paipu?

ʻO Polytetrafluoroethylene (pōkole ʻia ʻo PTFE), i kapa ʻia ʻo "Plastic King", he polymer molecular kiʻekiʻe i loaʻa ma ka polymerizing tetrafluoroethylene ma ke ʻano he monomer, he keʻokeʻo a i ʻole translucent.ʻAʻole i loko o kēia mea nā puaʻa a i ʻole nā ​​​​mea hoʻohui, a loaʻa iā ia nā ʻano o ka waikawa a me ke kūpaʻa alkali, ke kūʻē ʻana i nā mea hoʻoheheʻe kūlohelohe, a aneane hiki ʻole ke hoʻoheheʻe ʻia i nā solvents a pau.Eia kekahi, he ākea ākea ka PTFE a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma -65 ° C ~ 260 ° C ma lalo o ke kaomi maʻamau.Hana ʻia ia e ke ʻano o ka hoʻopili ʻana.ʻO nā paipu PTFE i hana ʻia me ka hoʻohana ʻana i ka extrusion paste he maʻalahi a hiki iā ia ke hana i nā paipu PTFE me nā anawaena o loko e like me ka liʻiliʻi e like me ka 0.3 mm a hiki i ka palena kiʻekiʻe o 100 mm a me ka mānoanoa o ka pā e like me ka liʻiliʻi e like me 0.1 mm a 2 mm.No laila, ʻo ka paipu polytetrafluoroethylene (PTFE) he huahana maʻalahi loa e hāʻawi i kahi ākea o nā noi i nā ʻoihana like ʻole.

No ke aha i hoʻohana nui ʻia ai nā paipu PTFE:

1. ʻO ke kūpaʻa wela kiʻekiʻe, hiki ʻole ke hoʻoheheʻe ʻia i kekahi solvent.Hiki iā ia ke kū i ka wela kiʻekiʻe a hiki i 300 °C i ka manawa pōkole, a maʻamau hiki ke hoʻohana mau ʻia ma waena o 200 °C a me 260 °C, me ke kūpaʻa wela nui.

2. ʻO ke kūpaʻa haʻahaʻa haʻahaʻa, ka ikaika mechanical maikaʻi i ka haʻahaʻa haʻahaʻa, ʻoiai inā e hāʻule ka mahana i -65 ℃, ʻaʻole e lilo i embrittled, a hiki iā ia ke mālama i ka 5% elongation.

3. ʻAʻole hiki ke pale aku i ka corrosion, inert i ka hapa nui o nā kemika a me nā mea hoʻoheheʻe, kū i nā waikawa ikaika a me nā alkalis, ka wai a me nā mea hoʻoheheʻe organik like ʻole, hiki ke pale i nā ʻāpana mai kēlā me kēia ʻano o ke kino kino.

4. Anti-kahiko, ma lalo o ka haawe kiʻekiʻe, loaʻa nā pono ʻelua o ka pale ʻana a me ka paʻa ʻole.ʻO ke ola ʻelemakule maikaʻi loa i ka plastic.

5. ʻO ka lubrication kiʻekiʻe, ka helu haʻahaʻa o ka friction ma waena o nā mea paʻa.Hoʻololi ka coefficient o friction i ka wā e paheʻe ai ka ukana, akā aia ka waiwai ma waena o 0.05-0.15 wale nō.No laila, loaʻa iā ia nā pōmaikaʻi o ka haʻahaʻa haʻahaʻa hoʻomaka a me ka hana maʻalahi no ka hana ʻana i nā bearings.

6. ʻO ka non-adhesion ka liʻiliʻi liʻiliʻi o ka ʻili o nā mea paʻa, a ʻaʻole pili i kekahi mea.ʻAʻole e pili nā mea ʻai a pau.ʻO nā kiʻiʻoniʻoni lahilahi loa e hōʻike ana i nā waiwai non-stick maikaʻi.

7. He mea ʻala ʻole, ʻono ʻole, ʻaʻohe mea ʻawaʻawa, physiologically inert, a ʻaʻohe hopena ʻino ke hoʻokomo ʻia i loko o ke kino e like me nā kīʻaha koko a me nā ʻāpana no ka manawa lōʻihi.

8. Māmā a maʻalahi.Hoʻemi nui i ka ikaika o ka hana a ka mea hoʻohana.

ʻO kekahi mau hoʻohana maʻamau o nā paipu PTFE:

1. ʻOihana Kemika

Ma muli o ko lākou kūpaʻa kiʻekiʻe kiʻekiʻe i nā mea kemika āpau, kūpono nā paipu PTFE no ka hoʻohana ʻana i ka ʻoihana kemika.Aia kēia me ka ʻoihana semiconductor.Pono nā kaʻina hana o kēia wā i ka hana semiconductor i ke ana palekana a me ka lawe ʻana i nā wai corrosive (ʻakika a me nā kumu).Hiki i kēia mau mea ke hōʻino nui i ka paipu hāʻawi i ka manawa pōkole.

2. ʻOihana kaʻa

I loko o ka mīkini kaʻa, hoʻohana ʻia nā paipu kiʻekiʻe i hana ʻia me ka PTFE no ka hoʻoheheʻe wahie a me nā kaʻa wahie.E like me nā paipu wahie, nā puʻu turbocharger, nā paipu hoʻoheheʻe, nā paipu hoʻoheheʻe ʻakomi, nā paipu pahu kaʻa kaʻa, nā ʻenekini diesel, nā paipu heihei a me nā puʻu mana hoʻokele.ʻO nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, ke kūpaʻa kiʻekiʻe, ke kūpaʻa a me ke kūpaʻa corrosion o ka paipu PTFE e loaʻa iā ia kahi ola lawelawe lōʻihi me ka hoʻololi pinepine ʻole.

3. ʻoihana paʻi 3D

I ka paʻi 3D, pono e hoʻoneʻe ʻia ke filament i ka nozzle paʻi, pono e hana ʻia ma kahi pae wela kiʻekiʻe.ʻO ka paipu PTFE ka polymer i makemake nui ʻia i ka ʻoihana paʻi 3D ma muli o kona koena wela kiʻekiʻe a me nā waiwai non-stick, e kōkua maʻalahi i ka hoʻoheheʻe ʻana i ka mea mai ka nozzle.

4.ʻoihana lapaʻau

ʻO nā waiwai kūikawā o nā paipu PTFE pū kekahi me kahi hoʻolālā maʻalahi e hoʻomaʻemaʻe.I nā makahiki i hala iho nei, ua hoʻohana nui ʻia nā paipu PTFE i nā mea lapaʻau.Ma muli o ka haʻahaʻa haʻahaʻa o ka friction o ka paipu PTFE, ʻo ia ka mea he ʻili maʻemaʻe loa ʻaʻole ia e pale a kōkua ʻole i ka ulu ʻana o ka bacteria.I waena o lākou, hoʻohana ʻia nā hoses no nā cannulas, catheters, pipettes a me endoscopes.

5. ʻOihana meaʻai

Ma muli o kāna mau hoʻomaʻemaʻe maʻalahi a me nā waiwai non-stick, hiki ke hoʻohana ʻia nā paipu PTFE i ka ʻoihana meaʻai.ʻO ka mea nui, kūpono nā paipu i hana ʻia me ka PTFE i hoʻopiha ʻole ʻia ma muli o ko lākou kūʻokoʻa physiological a hoʻokō i nā alakaʻi alakaʻi o ka US Food and Drug Administration.No laila, ua hōʻoia ʻia ʻaʻole ia e pōʻino i ka pili ʻana me ka plastic a me nā ʻano meaʻai.

ʻO ke kūʻai ʻana i ka paipu PTFE kūpono ʻaʻole wale e pili ana i ke koho ʻana i nā kikoʻī like ʻole no nā noi like ʻole.ʻOi aku e koho i kahi mea hana hilinaʻi.ʻO Besteflon Fluorine plastic Industry Co., Ltd. kūikawā i ka hana ʻana i nā paipu PTFE kiʻekiʻe a me nā paipu no 15 mau makahiki.Inā he nīnau a he pono, e ʻoluʻolu e nīnau mai iā mākou no ka ʻōlelo aʻo ʻoihana.
