Maikaʻi loa nā capillaries Ptfe, e hana ana i kahi pūʻulu o nā kikoʻī maʻamau kūʻokoʻa e like me kona hoʻohana ʻana.E like me ka pono like ʻole, e hana i ka paipu capillary ʻeleʻele, ka puʻupuʻu keʻokeʻo keʻokeʻo, ka puʻupuʻu capillary melemele, ka puʻu capillary ʻulaʻula a me ka puʻupuʻu capillary aniani a pēlā aku, ma ke ʻano he uliuli a i ʻole ka pahu ʻeleʻele.
- 1.Ptfe capillary kaʻina hana
ʻO ka Ptfe capillary tube he paipu kūikawā i hana ʻia e ka maloʻo ʻana, ka sintering kiʻekiʻe a me ka hoʻopau ʻana ma hope o ka hui ʻana i ka resin dispersion ptfe a me ka propellant, a laila hoʻokau ʻia i kekahi ikaika shearing i loko o ka waha me ka cone Angle.
Maikaʻi loa nā capillaries Ptfe, e hana ana i kahi pūʻulu o nā kikoʻī maʻamau kūʻokoʻa e like me kona hoʻohana ʻana.E like me ka pono like ʻole, e hana i ka paipu capillary ʻeleʻele, ka puʻupuʻu keʻokeʻo keʻokeʻo, ka puʻupuʻu capillary melemele, ka puʻu capillary ʻulaʻula a me ka puʻupuʻu capillary aniani a pēlā aku, ma ke ʻano he uliuli a i ʻole ka pahu ʻeleʻele.
- 2.Main hiʻona o ka ptfe capillary paipu
(1) He haʻahaʻa haʻahaʻa haʻahaʻa loa: kona friction coefficient maʻamau wale nō 0.04, he mea maikaʻi loa ia iho-lubricating mea, a me ka friction coefficient ʻaʻole e loli me ka mahana.
(2).Paʻa kemika kiʻekiʻe: hiki iā ia ke pale i nā waikawa ikaika a pau, me ka aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, alkali ikaika, oxidant ikaika, reducing agent a me nā mea hoʻoheheʻe organik.He kūpono loa no ka hanai kemika maʻemaʻe kiʻekiʻe.
(3).ʻAʻole maʻalahi ka hoʻopili ʻana i ka colloid a me nā kemika maikaʻi.
(4).ʻOi aku ka maikaʻi o ka hana insulation uila: ʻO PTFE kahi mea nonpolar nui me nā waiwai dielectric maikaʻi a me ke kūpaʻa nui.ʻO kāna mau dielectric ma kahi o 2.0, ʻo ia ka mea liʻiliʻi loa ma waena o nā huahana insulation uila.
(5) .Maʻalahi a maʻalahi.
(6) ʻAʻole maʻalahi ka hoʻopili ʻana i ka colloid a me nā kemika.
(7) .Part o ka'ōmole'ōmole, maʻalahi ke nānā i ke kūlana wai o loko.
3. Hoʻohana i ka ptfe capillary tube
Hoʻohana nui ʻia ia i ka ʻoihana kemika, ka ʻoihana chlor-alkali, ka mīkini, kaʻa, ka paipu hoʻomehana uila, ka pulp, ka mahu, ke kinoea i hoʻopaʻa ʻia, ka mea hoʻololi wela, ka uhi ʻana, ka textile, pharmaceutical, lāʻau lapaʻau, ʻoihana kaʻa, mīkini kope a me nā ʻoihana ʻē aʻe. e like me ka catheter.
Eia kekahi, hiki ke hoʻohana i ka fep (PVF a me ʻeono f propylene copolymer) i hana ʻia i ka ipu aniani, ʻo kāna kumu e hoʻomau i ka hana o ka ptfe, e like me: ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, kūpaʻa kemika, insulation uila, kaulana ʻaʻole pili a me ka ikaika mechanical kiʻekiʻe. , ma ka palena wela kiʻekiʻe 50 ℃ haʻahaʻa ma mua o ka ptfe.Akā ʻoi aku ka maʻalahi a me ka ʻike ma mua o ka ptfe, e maʻalahi ke ʻike i nā mea e hana nei i loko o ka lawe ʻana i nā wai a me nā kinoea.
