Njirimara ngwaahịa
Shell na tube PTFE okpomọkụ mgbanwe nwere ọtụtụ uru ma e jiri ya tụnyere ígwè mmewere okpomọkụ Exchangers.
1. Ebe ọ bụ na polytetrafluoroethylene (PTFE) bụ ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe (nke a na-akpọ F4) ma nwee ezigbo nkwụsị nke corrosion, a maara nke ọma nguzogide corrosion nke fluoroplastics. A na-eji ihe ọkụ ọkụ emechara na ihe karịrị 100 mgbasa ozi iji wepụ okpomọkụ dị elu. Ọ nwere ike ịrụ ọrụ n'ihe fọrọ nke nta ka ọ bụrụ mgbasa ozi niile ma e wezụga fluorine elemental, ọla alkali a wụrụ awụ, chlorine trifluoride, uranium hexafluoride, na kerosene perfluorinated.
2. Njirimara mgbochi. Ọkpụkpọ rọba fluorine nwere ebe dị larịị, nnukwu mgbasawanye ọkụ na nnukwu mgbanwe, na-eme ka ọ ghara ịdị na-akpakọba ọnụ ọgụgụ ma na-etolite oyi akwa. Ha nwere ezigbo nkwụsi ike nke kemịkalụ na ọtụtụ mgbasa ozi ma na-ebelata ngwaahịa corrosion nke ukwuu. ma ọ bụ pụọ. Elu dị larịị nwere ihe na-abawanye mmiri siri ike, enweghị nhịahụ na ọnụọgụ esemokwu dị oke ala, nke mere na a ga-ebelata ma ọ bụ kpochapụ unyi ma ọ bụ ọnụ ọgụgụ a na-etinye n'elu mgbidi ọkpọkọ. Fluoroplastics nwere nnukwu ọnụọgụ mgbasawanye ọkụ yana ezigbo mgbanwe. Igwe ọkụ na-ekpo ọkụ nke fluoroplastics, karịsịa mgbe a na-agbanye tubes mgbanwe okpomọkụ ka ọ bụrụ ihe mgbagwoju anya, ga-eme ka mkpọtụ nke tubes mgbanwe okpomọkụ kpatara site na mkpali nke mmiri ahụ, na-eme ka oyi akwa dị na mgbidi tube na-amakwa jijiji. dapụ. N'ihi ya, mgbidi tube nke okpomọkụ a na-anọgide na-adị ọcha n'oge ọrụ ogologo oge.
3. Obere nha, ịdị arọ dị arọ na nhazi kọmpat. The thermal conductivity nke fluoroplastic dị ala, naanị 0.19W / m.℃, nke bụ 1/250 nke nkịtị carbon ígwè. Iji belata nguzogide okpomọkụ nke mgbidi tube ma mee ka ọnụọgụ ọkụ na-ebufe ọkụ zuru oke, a na-ejikarị tubes ndị nwere mgbidi dị mkpa. Iji hụ na ike nke tubes nwere mgbidi dị mkpa, a ga-eji tubes dị ntakịrị mee ihe. N'ihi iji ọnụ ọgụgụ buru ibu nke obere tubes dayameta, ebe a na-ebufe okpomọkụ kwa otu olu dị ukwuu. Ihe Nlereanya: E jiri ya tụnyere ịdị arọ na olu nke otu 10-square-mita PTFE okpomọkụ okpomọkụ na metal ma ọ bụ na-abụghị metal graphite okpomọkụ Exchanger, PTFE okpomọkụ Exchanger bụ nanị banyere 1/2 nke ọzọ abụọ. Enwere ike ịhụ na ụdị okpomọkụ a nwere ike ịdị ntakịrị na nha dị arọ, si otú ahụ chekwaa njem, ntinye na ụgwọ ọrụ.
4. Ike mgbanwe. N'ihi na fluoroplastic ọkpọkọ dị nro, nwere ndụ ike ọgwụgwụ na-ehulata karịa 100,000 ugboro, yana ike mmetụta nke 1.09J / cm³ na -57 degrees na 1.63J / cm³ na 23 degrees, tube tube nwere ike ime n'ime dị iche iche chọrọ. ụdị pụrụ iche. , ma na-arụ ọrụ ntụkwasị obi ruo ogologo oge n'okpuru ọnọdụ mmetụta mmiri na ịma jijiji. Nke a siri ike iji ihe ndị ọzọ na-eguzogide corrosion rụzuo dị ka graphite, iko, ceramik na ọla ndị na-adịghị ahụkebe.
5. Ogologo ndụ ọrụ na nlekọta dị mfe. Ụlọ ọrụ anyị nwere nnukwu ntọala na nkwalite na nyocha na mmepe nke fluoroplastic okpomọkụ mgbanwe. A na-eji nwayọọ nwayọọ mee ka ihe ndị na-eme ka ịka nká na corrosion dị na ndị na-ekpo ọkụ na-eme ka ọ dịkwuo mma site na nzọụkwụ, na-emeziwanye nke mbụ. Dabere na nke a, anyị ga-emelite ọzọ ka mma ime mgbanwe na ndị ahịa anyị. Ka ọ dị ugbu a, ọtụtụ ndị na-emepụta ihe ejirila ndị na-ekpo ọkụ PTFE mee ihe karịrị afọ 5. N'ụzọ dị otú a, a na-echekwa nnukwu akụkụ nke mmefu ahụ na onye na-ekpo ọkụ naanị. . Nke abuo, PTFE okpomọkụ Exchanger dị mfe ịnọgide na-enwe. Ọ bụrụ na ntapu na-eme mgbe a na-eji ya eme ihe, enwere ike ịrụzi ya ma nwalee nrụgide ozugbo na saịtị. Nke a na-azọpụta ndị ahịa oge njem njem nke ịlaghachi na ụlọ ọrụ mmepụta ihe maka mmezi na mmepụta ihe na-akpata site na-adọba ụgbọala, nke siri ike iji nweta ndị ọzọ okpomọkụ.
6. Ọnụ ego bụ ebumnobi. Ọ bụ ezie na fluoroplastics dị ka ihe ndị na-enyefe ọkụ ka dị ọnụ ugbu a, na-eji obere tubes nwere mgbidi dị obere, mkpokọta nnyefe okpomọkụ nwere ike ịdị elu dị ka 500W / ㎡.℃. Enwere ike imepụta nke a n'ọtụtụ ebe n'okpuru ọnọdụ usoro nrụpụta zuru oke. Ụdị ihe na-ekpo ọkụ na-ekpo ọkụ, na nke ka mkpa, nkwụsị nke corrosion kacha elu nwere ike dochie ọla ndị na-adịghị ahụkebe, si otú ahụ na-echekwa nnukwu ego nke oriri ígwè na-adịghị ahụkebe. Na mgbakwunye, n'ihi uru nke nguzogide corrosion na nguzogide na-adịghị mma nke fluorine plastic heat exchangers, enwere ike nweta uru akụ na ụba ndị ọzọ n'oge eji. Ya mere, na-eburu n'uche ihe ndị dị ka mmepụta ihe, ntinye, ọrụ na mmezi, ọnụ ahịa n'ezie dị ntakịrị.
Uru ndị a dị n'elu ekwenyela n'ụzọ zuru ezu site na fluoroplastic okpomọkụ nke a na-eji na-emepụta mmepụta ihe, a na-ejikwa ya na mgbasa ozi dị iche iche na mba ọzọ.
