Ni irihe tandukaniro riri hagati ya PTFE na ePTFE?
PTFE, mu magambo ahinnye ya polytetrafluoroethylene, ni fluoropolymer y’ubukorano ya tetrafluoroethylene. Uretse kuba idakunda amazi, bivuze ko ibuza amazi,PTFEirwanya ubushyuhe bwinshi; ntabwo igirwaho ingaruka n'imiti myinshi n'ibintu biyigize, kandi itanga ubuso budashobora gufata ikintu na kimwe.
Ubwoko bw'ikusanyirizo ry'umukungugu
Ku bakoresha uburyo bubiri busanzwe bwo gukusanya ivumbi ryumye, bakoresha filters zo mu nzu, hari amahitamo abiri asanzwe – sisitemu zo gukusanya ivumbi (izi ni sisitemu zishaje zigenda zigabanuka buri munsi), aho ivumbi rihungizwa kugira ngo rikureho uduce twangiritse, na pulse jet (izwi kandi nko gusukura umwuka ufunze), aho umwuka ushyushye cyane ukoreshwa mu gukura ivumbi mu ivumbi.
Inzu nyinshi zikoresha imifuka miremire ifite ishusho y'umurambararo ikozwe mu mwenda uboshye cyangwa ukozwe mu ipamba nk'uburyo bwo kuyungurura. Ku bijyanye n'ivumbi rito rikabije n'ubushyuhe bwa gaze bwa 250 °F (121 °C) cyangwa munsi yayo, hari igihe amakarito afite impande n'amapine, adafunze, rimwe na rimwe akoreshwa nk'ibikoresho byo kuyungurura aho gukoresha imifuka.
Ubwoko bw'ibikoresho byo gushungura imifuka
Ku bijyanye n'ibikoresho byakoreshejwe mu gukora icyuma gitunganya ubushyuhe, hari amahitamo menshi aboneka. Ibi bikoresho byihanganira ubushyuhe butandukanye, bitanga urwego rutandukanye rw'ubushobozi bwo gukusanya, bishyigikira ubushobozi butandukanye bwo kwihanganira ibikoresho byo kwangirika, kandi bitanga ubushobozi butandukanye bwo guhuza ibinyabutabire n'imiti.
Amahitamo y'ibikoresho (ashobora gutangwa mu buryo bwo kuboha cyangwa/cyangwa bwakozwe) arimo ipamba, polyester, micro denier felts zikora neza cyane, polypropylene, nylon, acrylic, aramid, fiberglass, P84 (polyimide), PPS (polyphenylene sulfide)
Ubwoko bw'ibirahuri byo kuyungurura
Umaze guhitamo igikoresho cyo gushyiramo amasashe yawe yo kuyungurura, amahitamo akurikira azaba ari ukureba niba ugomba kuyashyiramo cyangwa utayashyiramo. Gukoresha uburyo bukwiye bwo kurangiza (cyangwa uburyo bwo kurangiza rimwe na rimwe) bishobora gutuma isashe yawe ikora neza cyane, bigatuma irekurwa rya keke rigabanuka, kandi bikarinda imimerere mibi yo kuyishyiramo.
Ubwoko bw'ibikoresho birimo ibirangisho birimo ibirangisho byatwitswe, ibirangisho byashyizwemo irangi, bigabanya umuriro, birwanya aside, birwanya imirasire y'umuriro, birwanya static, na oleophobic, ni ukuvuga bike gusa.
PTFE ishobora gukoreshwa nk'umusozo mu buryo bubiri butandukanye—nk'urukiramende ruto cyangwa nk'igitambaro/ubwogero.
Ubwoko bw'ibirahuri bya PTFE
Reka dutangire dusuzuma akayunguruzo k’isanduku gakozwe mu buryo bw’agafuka ka polyester. Iyo agafuka kari gukoreshwa, bimwe mu bice by’umukungugu bizajya mu byuma. Ibi byitwa kuyungurura umuvuduko w’amazi. Iyo agafuka kazungurutse, cyangwa umwuka urimo guhumeka ugashyirwa mu cyuma kugira ngo gakureho ibice byacitse, bimwe mu bice bizagwa mu cyuma gipfundikiye bigakurwa muri sisitemu, ariko ibindi bizakomeza kwinjira mu mwenda. Uko igihe kigenda gihita, ibice byinshi bizagenda byinjira mu mwenge w’icyuma maze bigatangira guhuma amaso icyuma gipfukirana, ibyo bikazagabanya imikorere y’icyuma mu bihe bizaza.
Ururenda rwa ePTFE rushobora gushyirwa ku masashi asanzwe kandi afite imigozi yakozwe mu buryo buboshye kandi bukozwe mu buryo bukozwe mu buryo buboshye kandi bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bukozwe mu buryo bwa mikorosikopi (nk'uko "impapuro zipfunyika mu gikoni" zigaragaza ishusho y'isashishwa) kandi zigashyirwa mu ruganda inyuma y'isashishwa. Muri iki gihe, ururenda ruzongera cyane ubushobozi bw'isashishwa (aho "ubushobozi" muri uru rwego buvuga umubare n'ingano y'uduce tw'umukungugu turimo kuyungururwa). Niba isashishwa ya polyester itarangije gukora neza ikagira ubushobozi bwa 99% ku duce twa mikorosikopi ebyiri cyangwa nini, urugero, kongeramo ururenda rwa ePTFE bishobora gutuma uduce twa mikorosikopi tugera kuri mikorosikopi imwe cyangwa tukagira ubushobozi bwa 99.99% ku duce twa mikorosikopi 1 no kuba duto, bitewe n'umukungugu n'imiterere y'imikorere. Byongeye kandi, imiterere idafatana y'ururenda rwa ePTFE bivuze ko kunyeganyega isashishwa cyangwa gushyiramo umuvuduko w'ingufu bizatuma ivumbi ryinshi rikurwaho kandi rikureho cyangwa rigabanye kuyungurura no guhuma ku buzima bw'ururenda (utwo duce tuzangirika uko igihe kigenda gihita; kandi, kugira ngo twongere igihe cyatwo, ntidukwiye gukoreshwa hamwe n'uduce tw'umukungugu dukoreshwa mu buryo bukabije).
Nubwo membrane ya ePTFE ari ubwoko bw'irangi, hari abantu bafata ijambo "irangi rya PTFE" nko koga cyangwa gutera PTFE ku gikoresho cyo kuyungurura. Muri iki gihe, imigozi y'igikoresho iba ifungishijwe muri PTFE ukwayo. Irangi rya PTFE ryo muri ubwo bwoko ntirizamura imikorere myiza yo kuyungurura, kandi igikoresho gishobora gukomeza kuba kinini, ariko iyo hakoreshejwe icyuma gitera impumuro, igikoresho kizasukurwa byoroshye bitewe n'irangi ritoshye PTFE itanga ku migozi.
Ni ikihe cyiza kurusha ibindi: Uduce twa ePTFE cyangwa PTFE?
Agafuka kongereweho agace ka ePTFE gashobora kongera imikorere kugeza kuri 10X cyangwa zirenga, koroshya gusukura, kandi ntikazagira ikibazo cyo gukurura ubujyakuzimu. Nanone, agakapu ka ePTFE ni keza ku ivumbi rifata kandi rifite amavuta. Ugereranije, agakapu katari utwenda twavuwe n'umusemburo wa PTFE ntikazagira imikorere myiza kandi kazakomeza kuba gafite ubujyakuzimu, ariko bizoroha gusukura kuruta iyo gasigaye gakozwe.
Mu bihe byashize, rimwe na rimwe, guhitamo hagati y’urukiramende rwa ePTFE n’urukiramende rwa PTFE byaterwaga n’ikiguzi kuko ururamire rwari ruhenze, ariko igiciro cy’udufuka twa membrane cyaragabanutse mu myaka ya vuba aha.
Ibi byose bishobora gutera ikibazo: “Niba udashobora gutsinda membrane ya ePTFE kugira ngo ugire umusaruro mwiza kandi wirinde ko ubujyakuzimu bugabanuka, kandi niba igiciro cy'agafuka k'urukiramende cyaragabanutse ku buryo gihenda gato ugereranyije n'agafuka gafite irangi rya PTFE, kuki utahitamo membrane ya ePTFE?” Igisubizo ni uko udashobora gukoresha membrane ahantu hari ivumbi kuko - nubikora - ntuzamara igihe kinini ufite membrane. Ku bijyanye n'ivumbi rikabije, PTFE ni yo nzira nziza.
Nubwo bimeze gutyo, guhitamo uburyo bukwiye bwo guhuza filter media n'uburyo bwo kurangiza filter (cyangwa uburyo bwo kurangiza) ni ikibazo gifite ingero nyinshi, kandi igisubizo cyiza gishingiye ku bintu byinshi.
