Hose PTFE vs. PVC Hose: Nā ʻokoʻa a me nā ʻano

I loko o nā ʻōnaehana hoʻoili wai, hoses e lawelawe i ke alahaka koʻikoʻi ma waena o nā mea hana a me ka media, a pili pono kā lākou hana i ka paʻa a me ka palekana o ka ʻōnaehana PTFE hoses a me PVC hoses, ma ke ʻano he ʻelua ʻano maʻamau o nā mea hose, loaʻa kēlā me kēia me nā pono kūikawā a me nā noi. ʻO ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o lākou hiki ke kōkua iā mākou e hana i nā koho kūpono e pili ana i nā pono maoli.

• ʻO ka haku melemele a me ke kūpaʻa

Hana ʻia ka hose PTFE me nā mea polytetrafluoroethylene, nona ka paʻa kemika kiʻekiʻe loa a aneane ʻaʻole i hoʻopilikia ʻia e kekahi mea. Hiki iā ia ke pale aku i ka hoʻouka ʻana o nā media corrosive e like me nā waikawa, alkalis, a me nā paʻakai. ʻAʻole loaʻa i loko o kāna ʻano molekala nā paʻa pālua carbon-carbon no laila he kiʻekiʻe ke kūpaʻa oxidation. ʻO ka hoʻohālikelike, ʻo ka hose PVC he resin synthetic polymerized mai nā monomers vinyl chloride. ʻOiai he maikaʻi ke kūpaʻa corrosion, ʻoi aku ka haʻahaʻa o kona kūpaʻa kemika a me ke kūpaʻa oxidation. ʻO kēia ʻokoʻa ka mea i ʻoi aku ka maikaʻi o ka hose PTFE i nā wahi ʻino loa.

• Nā hiʻohiʻona hana

Hana maikaʻi nā hoses PTFE ma ke ʻano o ka hana. ʻO ko lākou mau paia i loko, maʻemaʻe me ka haʻahaʻa friction coefficient, hiki ke hōʻemi pono i ke kūʻē ʻana i ka wā a hoʻemi i ka ʻaʻahu o nā mea hana. Hoʻohui ʻia, loaʻa i nā paipu PTFE ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, e ʻae iā lākou e hana paʻa i kahi ākea ākea -250 ℃ a 260 ℃ me ka ʻole o ka palupalu a ʻelemakule. Ma ka ʻaoʻao ʻē aʻe, ʻo nā hoses PVC, ʻoiai e loaʻa ana kekahi mau maʻalahi a me ka tensile, hiki ke hoʻololi ʻia i nā wela kiʻekiʻe, e kaupalena ana i kā lākou hoʻohana ʻana i nā wahi wela.

ʻO nā paipu PTFE, ma muli o ko lākou kūpaʻa kemika maikaʻi loa, ke kūpaʻa kiʻekiʻe o ka wela, a me ke kūpaʻa ʻana i ka lole, ua hoʻohana nui ʻia i nā ʻoihana e like me ke kemika, ke kinoea maoli, ka meaʻai, a me nā lāʻau lapaʻau kahi e koi ʻia ai nā mea paipu kiʻekiʻe. Ua kūpono loa lākou no ka lawelawe ʻana i nā media corrosive a me nā wahi kiʻekiʻe. Ma ka lima ʻē aʻe, hoʻohana nui ʻia nā hoses PVC, me kā lākou kumu kūʻai haʻahaʻa a me ka hana hoʻoponopono maikaʻi, i ke kūkulu ʻana i ka hoʻoheheʻe wai, ka hoʻoheheʻe ʻana, nā ʻōnaehana wai, a me nā kahua uila a me nā kahua uila kahi e pono ai ka hoʻonohonoho pono ʻana a me ka hoʻokele kumukūʻai. Aia nā ʻokoʻa nui o nā waiwai waiwai a me nā kahua noi ma waena o nā mea ʻelua.

I ka hopena, hōʻike hou mākou i ka ʻokoʻa a me ka hoʻohui ʻana o kēia mau mea hose ʻelua. ʻO nā paipu PTFE, me ko lākou kūpaʻa kemika maikaʻi loa, a me ke kūpaʻa ʻana i ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ua lilo i mea makemake no ka hana kiʻekiʻe a me nā kūlana hana koʻikoʻi. Ma kekahiʻaoʻao,ʻo PVC, me ko lākou kumukūʻai a me ka maʻalahi o ka hanaʻana, ua loaʻa i ko lākou wahi ma nāʻanoʻoihana. ʻO ke koho ʻana o ka hose e hoʻohana ʻaʻole pili wale i ka hopena akā i ka hana holoʻokoʻa a me ka palekana o ka ʻōnaehana.
