Nthawi zambiri amagwiritsa ntchito kafukufuku wopangidwa kapena asayansi, chipinda choyera ndi malo ovomerezeka omwe ali ndi dothi lotsika monga fumbi, ma virusne, mabowo a aerosol. Kuti mukhale ndendende, chipinda choyera chimakhala ndi vuto lolamulidwa lomwe limafotokozedwa ndi kuchuluka kwa tinthu ta cubic meter pamtunda wa tinthu tating'onoting'ono. Mpweya wozungulira kunja kwa mzinda wamba wapamtunda umakhala ndi tinthu 35,000,000 mita imodzi ya cubic, 0,5 micron ndi yayikulu mchipinda choyera kwambiri cha malo otsika.
Yeretsani chipinda chizikitiro
Zipinda zoyera zimagwiritsidwa ntchito pafupifupi malonda aliwonse omwe tinthu tating'onoting'ono timatha kusokoneza zochita zopanga. Amasiyana kukula ndi zovuta, ndipo amagwiritsidwa ntchito kwambiri m'mafakitale a semicopakec, kachilombo ka mankhwala, komanso zida zamankhwala, zankhondo ndi zida zankhondo.
Chipinda choyera ndi malo omwe anali nawo omwe amaperekedwa kuti achepetse mawonekedwe a tinthu ndikuwongolera magawo ena ndi chilengedwe monga kutentha, chinyezi komanso kupsinjika. Gawo lalikulu ndi gawo lothandiza kwambiri la mpweya (hepa) fyuluta yomwe imagwiritsidwa ntchito kutchera tinthu tating'onoting'ono tomwe ndi 0.3 micron ndi yayikulu kukula. Ndende zonse zoperekedwa kuchipinda choyera zimadutsa zosefera za hepa, ndipo nthawi zina zokhala ndi zingwe zolimbitsa thupi ndizofunikira, Ulpa) zosefera (ulpa) zosewerera.
Ogwira ntchito omwe adasankhidwa kuti agwire ntchito zoyera amaphunzitsidwa bwino kwambiri pakuwongoleredwa. Amalowa ndikutuluka m'chipinda choyera kudzera muirlocks, mvula yamtundu wa ndege ndi / kapena zipinda zobiriwira, ndipo ayenera kuvala zovala zapadera zomwe zimapangidwa ndi khungu ndi thupi.
Kutengera ndi chipinda cha chipinda kapena ntchito, zokutira za ogwira ntchito zitha kukhala zochepa ngati zovala za labu ndi makeke, kapena monga kuchuluka kokhazikika mu suti imodzi yolumikizidwa ndi avaturatus.
Zovala zoyera zimagwiritsidwa ntchito poletsa zinthu kuti zitulutsidwe thupi la wovala ndi kuipitsa chilengedwe. Kuvala Chipinda Chodekha Chosayenera Kutulutsa tinthu tating'onoting'ono kapena ulusi kuti tisadetse chilengedwe ndi anthu ogwira ntchito. Mtundu wamtunduwu umatha kunyoza ntchito mu semiconductor ndi mafakitale opangira mankhwala ndipo amatha kuyambitsa matenda pakati pa ogwira ntchito zamankhwala ndi odwala omwe ali pakompyuta.
Omwe amabzala zipinda amaphatikizapo nsapato, nsapato, zovala, zophimba, zopindika, zovala zam'maso, mabowo, manja ndi zophimba nsapato. Mtundu wa zovala zoyera zomwe amagwiritsidwa ntchito kuyenera kuwonetsa chipinda choyera ndi mawonekedwe a mankhwala. Zipinda zoyera zochepa zitha kungofuna nsapato zapadera zokhala ndi mawonekedwe owoneka bwino omwe samatsata fumbi kapena litsiro. Komabe, mabotolo a nsapato sayenera kupanga ngozi zongodutsa chifukwa chitetezedwe chimakhala patsogolo. Chipinda choyera cha chipinda chimafunikira kuti chilowe mchipinda choyera. Ophunzira zipinda 10,000 oyeretsa amatha kugwiritsa ntchito zikondwerero zosavuta, chimakwirira, ndi boonies. Kwa kalasi 10 Zipinda zoyeretsa, njira zotayirira zotayika zokhala ndi chivundikiro cholumikizidwa chonse, nsapato, magolovesi ndi ma cell omaliza amafunikira.
Mfundo zoyenerera za chipinda
Zipinda zoyera zimasungabe mpweya wabwino kudzera mu kugwiritsa ntchito zosefera za Spa kapena ULPA kugwiritsa ntchito njira zoyendetsera ma laminar kapena mpweya. Ma laminar, kapena makina osagwirizana, mpweya wotsika mpweya wosefera pansi mopitilira muyeso. Makina oyenda a laminar Air oyenda nthawi zambiri amagwiritsidwa ntchito podutsa 100% ya denga kuti asunge mayendedwe osakhazikika. Malonda a Laminar nthawi zambiri amatchulidwa m'malo ogwirira ntchito (mabondo a LF), ndipo akumbukiridwa ku ISO-1 kudzera mchipinda choyera cha ISo-4.
Kupanga koyenera koyenera koyenera kumazungulira mpweya wogawa mpweya, kuphatikizapo zokolola zokwanira, zotsika kwambiri. M'malo ofuula ofuula, izi zikutanthauza kuti kugwiritsa ntchito mpweya wotsika kumabwezeretsa mozungulira. Pogwiritsa ntchito mapulogalamu oyenda mozungulira, pamafunika kugwiritsa ntchito mpweya kutsika pamalire a njirayi. Kugwiritsa ntchito madeya okwera ndege kumakhala kotsutsana ndi kapangidwe koyenerera koyenera kuchipinda koyenera.
Yeretsani chipinda cha chipinda
Zipinda zoyera zimawerengedwa ndi momwe mpweya umayeretsera. Mu feduro muyezo 209 (a mpaka d) wa USA, kuchuluka kwa tinthu kofanana ndi mamita 0,5μm. Misonkhano iyi imavomerezedwanso mu mtundu wa 259e wa muyezo. Federal muyezo 209e amagwiritsidwa ntchito motalika. Muyezo watsopano ndi tc 209 kuchokera ku bungwe lapadziko lonse lapansi. Miyezo yonseyi imafotokoza chipinda choyera ndi kuchuluka kwa tinthu tating'onoting'ono tomwe timapezeka mu mlengalenga wa labotale. Miyezo yoyeserera ya chipinda cha FS 209E ndi iso 14644-1 imafunikira gawo lakuti tinthu tating'onoting'ono ndi kuwerengetsa kuti zikhale bwino chipinda choyera kapena malo oyera. Ku UK, Standard Standard 5295 imagwiritsidwa ntchito polemba zipinda zoyera. Muyezo uwu watsala pang'ono kukwezedwa ndi BS EN ISO ASO 14644-1.
Zipinda zoyera zimawerengedwa malinga ndi kuchuluka ndi kukula kwa tinthu tating'onoting'ono tomwe timaloledwa. Ambiri ngati "gulu la 100 Muyeso umathandizanso kutanthauzira, kotero ndikotheka kufotokozera mwachitsanzo, kalasi 2000. "
Ziwerengero zazing'ono zimatchula za ISO 14644-1, yomwe imatchula mtundu wa decolithm ya chiwerengero cha tinthu 0,1 μm kapena chokulirapo kuloledwa pa mita ya mpweya. Chifukwa chake, mwachitsanzo, chipinda choyera cha ISO chimakhala nacho pa 105 = 100,000 pazinthu pa M³.
Onse awiri a FS 209e ndi Iso 14644-1 APTION Maubwenzi a Log Log-tinthu kukula ndi tinthu tating'onoting'ono. Pachifukwa chimenecho, palibe zinthu monga zero tinthu tating'onoting'ono. Mphepo yachipinda wamba ndi kalasi pafupifupi 1,000,000 kapena ISO 9.
