Inowanzo shandiswa mukugadzira kana tsvagiridzo yesainzi, kamuri yakachena inzvimbo inodzorwa ine mwero wakaderera wezvinosvibisa zvakaita seguruva, hutachiona hwemhepo, aerosol particles, uye kemikari mhute.Kuti ive chaiyo, kamuri rakachena rine mwero wakadzorwa wekusvibiswa unotsanangurwa nenhamba yezvimedu pacubic metre pachiyero chakatarwa.Mhepo yekunze iri kunze munharaunda yeguta ine zvidimbu 35,000,000 pa cubic metre, 0.5 micron uye yakakura mudhayamita, inoenderana neISO 9 kamuri rakachena iro riri padanho rakaderera remakamuri akachena.
Yakachena Room Overview
Makamuri akachena anoshandiswa mune ingangoita indasitiri yese umo zvidiki zvidiki zvinogona kukanganisa maitiro ekugadzira.Izvo zvakasiyana muhukuru uye kuoma, uye anoshandiswa zvakanyanya mumaindasitiri akadai semiconductor kugadzira, mishonga, biotech, mushonga wezvokurapa uye hupenyu sainzi, pamwe neyakaomarara nzira yekugadzira inojairika muaerospace, optics, mauto uye Dhipatimendi reMasimba.
Imba yakachena inzvimbo ipi neipi yakapihwa inopihwa kudzikisa kusvibiswa uye kutonga mamwe maparamendi ezvakatipoteredza senge tembiricha, humidity uye kudzvanywa.Chinhu chakakosha ndeye High Efficiency Particulate Air (HEPA) sefa iyo inoshandiswa kuteya zvidimbu zvine 0.3 micron uye yakakura muhukuru.Yese mhepo inounzwa mukamuri yakachena inopfuura neHEPA mafirita, uye mune dzimwe nguva uko kuomarara kuita kwehutsanana kuchidikanwa, Ultra Low Particulate Air (ULPA) mafirita anoshandiswa.
Vashandi vanosarudzwa kuti vashande mumakamuri akachena vanodzidziswa zvakanyanya mudzidziso yekudzora kusvibiswa.Ivo vanopinda nekubuda mukamuri rakachena kuburikidza neairlocks, mhepo yekugezera uye / kana makamuri ekupfeka, uye vanofanirwa kupfeka zvipfeko zvakakosha zvakagadzirirwa kuteya zvinosvibisa zvinongogadzirwa neganda nemuviri.
Zvichienderana nechikamu chekamuri kana basa, zvipfeko zvevashandi zvinogona kunge zvakaganhurirwa semajasi erabhoritari uye mambure ebvudzi, kana akawedzera sekufukidzwa zvizere mune akawanda akaturikidzana masutu ane midziyo yekufema.
Mbatya dzemukamuri dzakachena dzinoshandiswa kudzivirira kuti zvinhu zvisabudiswe pamuviri wemunhu akapfeka uye zvinosvibisa nharaunda.Chipfeko chemukamuri chakachena pachacho hachifanire kuburitsa zvidimbu kana mafiber kudzivirira kusvibiswa kwenharaunda nevashandi.Rudzi urwu rwekusvibiswa kwevashandi runogona kukanganisa mashandiro echigadzirwa mu semiconductor uye maindasitiri emishonga uye zvinogona kukonzera kutapukira pakati pevashandi vekurapa nevarwere muindasitiri yehutano semuenzaniso.
Zvipfeko zvemukamuri zvakachena zvinosanganisira bhutsu, shangu, maapuroni, zvivharo zvendebvu, zvivharo, zvivharo, masks echiso, majasi / lab majasi, gown, magurovhosi uye machira emunwe, mambure ebvudzi, hood, maoko uye mavhavha eshangu.Rudzi rwembatya dzemukamuri dzakachena dzinoshandiswa dzinofanirwa kuratidza kamuri yakachena uye zvakatemwa zvechigadzirwa.Dzimba dzakachena dzepasi-pamwero dzingangoda bhutsu dzakakosha dzine masoles akatsetseka asingateveri muguruva kana tsvina.Nekudaro, mabhoti eshangu haafanire kugadzira njodzi dzinotsvedza nekuti kuchengetedza nguva dzose kunotungamira.Sutu yekamuri yakachena inowanzodiwa pakupinda mukamuri yakachena.Kirasi 10,000 dzimba dzakachena dzinogona kushandisa masikisi, mabutiro emusoro, uye bhutu.Kumakamuri akachena eKirasi 10, chenjedzo yekupfeka gauni rine chivharo chine zip zvese, bhutsu, magurovhosi uye yakazara yekufemerera yakavharirwa inodiwa.
Clean Room Air Flow Principles
Makamuri akachena anochengetedza mhepo-isina mhepo kuburikidza nekushandiswa kweHEPA kana ULPA mafirita anoshandisa laminar kana mhirizhonga yekuyerera kwemhepo.Laminar, kana unidirectional, mhepo inoyerera masisitimu anonangisa mhepo yakasefa ichidzika pasi murukova runogara.Laminar mhepo inoyerera masisitimu anowanzo shandiswa kuyambuka 100% yesirin'i kuti arambe achiyerera, unidirectional kuyerera.Laminar kuyerera maitiro anowanzo kutaurwa munzvimbo dzinotakurika dzebasa (LF hoods), uye inopihwa muISO-1 kuburikidza neISO-4 yakakamurwa makamuri akachena.
Yakakodzera yakachena dhizaini yekamuri inotenderedza iyo yese mhepo yekugovera hurongwa, kusanganisira zvigadziro zvekukwana, kuzasi kwemhepo inodzoka.Mumakamuri ekuyerera akatwasuka, izvi zvinoreva kushandiswa kwemhepo yakaderera yemadziro inodzoka yakatenderedza perimeter yenzvimbo.Mumashandisirwo ekuyerera akatwasuka, zvinoda kushandiswa kwemhepo inodzoka pamuganhu wakadzika wenzira.Kushandiswa kwesirin'i yakaiswa mhepo inodzoka inopesana neiyo yakachena kamuri system dhizaini.
Yakachena Room Classifications
Dzimba dzakachena dzinoiswa mumapoka maererano nekuchena kwakaita mhepo.MuFederal Standard 209 (A kusvika D) yekuUSA, huwandu hwezvikamu zvakaenzana nehukuru kupfuura 0.5µm hunoyerwa mucubic tsoka imwe yemhepo, uye kuverenga uku kunoshandiswa kurongedza imba yakachena.Iyi metric nomenclature inogamuchirwawo mune yazvino 209E vhezheni yeStandard.Federal Standard 209E inoshandiswa munyika.Iyo nyowani chiyero ndeyeTC 209 kubva kuInternational Standards Organisation.Mipimo yese iri miviri inoronga imba yakachena nenhamba yezvikamu zvinowanikwa mumhepo yerabhoritari.Iyo yakachena kamuri yemhando zviyero FS 209E uye ISO 14644-1 inoda yakatarwa particle count kuyerwa uye kuverenga kurongedza hutsanana hutsanana hwekamuri yakachena kana nzvimbo yakachena.MuUK, British Standard 5295 inoshandiswa kurongedza makamuri akachena.Iyi chiyero chave kuda kukwidziridzwa neBS EN ISO 14644-1.
Makamuri akachena anorongwa maererano nenhamba uye saizi yezvimedu zvinotenderwa pavhoriyamu yemhepo.Nhamba huru dzakaita se "kirasi 100" kana "kirasi 1000" dzinoreva FED_STD-209E, uye dzinoratidza huwandu hwezvikamu zvehukuru 0.5 µm kana yakakura inobvumidzwa pa cubic tsoka yemhepo.Iyo chiyero inobvumirawo kududzira, saka zvinokwanisika kutsanangura semuenzaniso "kirasi 2000."
Nhamba diki dzinoreva ISO 14644-1 mwero, iyo inotsanangura iyo decimal logarithm yehuwandu hwezvikamu 0.1 µm kana yakakura inotenderwa pa cubic mita yemhepo.Saka, semuenzaniso, ISO kirasi 5 kamuri yakachena ine akawandisa 105 = 100,000 zvimedu pa m³.
Ose ari maviri FS 209E uye ISO 14644-1 anofungidzira log-log hukama pakati pehukuru hwechikamu uye particle concentration.Nechikonzero ichocho, hapana chinhu chakadai se zero particle concentration.Wakajairika mukamuri mhepo inenge kirasi 1,000,000 kana ISO 9.
