Hiki ke kū i ka wela kiʻekiʻe?

Hiki i ke kiʻekiʻe-press teflon hose ke kū i ka wela kiʻekiʻe, ehia mau degere, e hilinaʻi nui ʻia i kāna mau ʻano kikoʻī kikoʻī, ka mānoanoa, ka hoʻohana ʻana i ke kaiapuni a me ka mālama ʻana i ka ʻili a me nā mea ʻē aʻe.

Palena pale wela kiʻekiʻe

1. Laulā nui:

ʻO ka mea maʻamau, hiki i ka hose teflon kiʻekiʻe ke kūpaʻa i kahi mahana kiʻekiʻe mau ma kahi o 260 degere.

Ma lalo o ke kūlana o ka wela kiʻekiʻe koke, hiki i kona mahana hoʻomanawanui ke hiki i 400 degere.

2. Kūlana kūikawā

I kekahi mau kūlana kūikawā, e like me ka haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa holo kinoea, ʻoi aku ka kiʻekiʻe o ke kūpaʻa wela o ka hose teflon kiʻekiʻe, a hiki i 300 ° C.

Nā hiʻohiʻona waiwai

Hana ʻia nā hose teflon kiʻekiʻe me nā mea polytetrafluoroethylene (PTFE), nona ka pale wela maikaʻi loa. He paʻa kemika ka PTFE, hiki ke ʻae i nā ʻakika ikaika a pau (me ka aqua regia), nā oxidants ikaika, nā mea hoʻohaʻahaʻa a me nā mea hoʻoheheʻe ʻano like ʻole koe nā metala alkali hoʻoheheʻe, fluorinated media a me ka sodium hydroxide ma luna o 300 ° C. High-pressure teflon hose kekahi mau ʻano. ʻO ke kū'ē a me ka lubrication pono'ī, ka mea haʻahaʻa friction coefficient, i hana ia i loko o nā ʻano paʻakikī paʻakikī hiki ke mālama i kahi kūlana hana paʻa.

Nā hiʻohiʻona noi

Hoʻohana nui ʻia ka hose teflon kiʻekiʻe i ka ʻoihana kemika, ka lāʻau lapaʻau, ka hoʻoili ʻana i nā meaʻai a me nā ʻoihana ʻē aʻe ma muli o kona kūlana kiʻekiʻe kiʻekiʻe, haʻahaʻa haʻahaʻa a me ke kūpaʻa corrosion. I ka ʻoihana kemika, hiki iā ia ke lawe maikaʻi i nā ʻano kemika āpau; i ka ʻoihana lāʻau lapaʻau, hiki iā ia ke hōʻoia i kahi kaʻa kaʻa maʻemaʻe a sterile; ma ke kahua hana meaʻai, hiki iā ia ke hōʻoiaʻiʻo i ka palekana o ka meaʻai a me ka maʻemaʻe.

Nā kikoʻī e hoʻomaopopo

1. ʻO ka hoʻonui ʻana i ka wela a me ka hoʻohaʻahaʻa ʻana: ʻoiai hiki i ke kiʻekiʻe-press teflon hose ke kū i nā haʻahaʻa haʻahaʻa a hiki i -190 degere, akā ʻo ka hoʻohana ʻana i ka wela haʻahaʻa haʻahaʻa, pono e noʻonoʻo i ka hoʻonui wela a me ka hoʻohaʻahaʻa ʻana i ka hana hose. ʻO ka palena maʻamau palekana a maikaʻi hoʻi o ka hoʻohana ʻana ua ʻōlelo ʻia ma kahi o -70 degere.

2. Ka palena o ke kaomi: ma waho aʻe o ke kūpaʻa wela kiʻekiʻe, hiki i ke kiʻekiʻe-pressure teflon hose ke kū i ke kaomi kiʻekiʻe (e like me ka 100 bar), akā i nā noi hana pono e koho i nā kikoʻī hose kūpono a me nā hiʻohiʻona e like me nā kūlana kikoʻī.

ʻO ke kiʻekiʻe-press teflon hose ma lalo o nā kūlana maʻamau e kū i ke kiʻekiʻe kiʻekiʻe mau o ka 260 degere, hiki i ke kiʻekiʻe kiʻekiʻe koke ke hiki i 400 degere. Ma lalo o kekahi mau kūlana, ʻoi aku ka kiʻekiʻe o kona pale wela. Eia nō naʻe, i ka hoʻohana ʻana i ka pono e hoʻolohe i ka hoʻonui ʻana i ka wela a me ka hoʻohaʻahaʻa ʻana i ka hopena o ke kaomi kaomi a me nā mea ʻē aʻe.
