Biological kuchengetedza makabati ndiyo imwe yenzira dzekutanga dzekuchengetedza mune chero marabhoritari marongero anobata nehutachiona uye hutachiona. Aya akavharirwa, ane mhepo anopinza mhepo anovimbisa kuti pakubata zvinosvibisa zvingangove nengozi, vashandi vemurabhoritari vanochengetwa vakachengeteka uye vakaparadzaniswa neutsi uye kupararira kwezvikamu zvine ngozi.
Kuchengetedza mazinga anodiwa edziviriro, biological kuchengetedza makabati anofanirwa kugara achiyedzwa uye kupihwa certification, uye ari pasi peNSF/ANSI 49 Standard. Kangani makabati ekuchengetedza zvipenyu anofanirwa kupihwa zvitupa? Mumamiriro ezvinhu akajairika, ingangoita mwedzi gumi nemiviri yega yega. Izvi zvinofanirwa kuverengera huwandu hwekutanga hwe "kupfeka uye kubvarura" uye kubata kunoitika pamusoro pegore rekushandiswa kwekabati. Kune mamwe mamiriro, semiannual (kaviri-pagore) bvunzo inodiwa.
Kune mamwe akati wandei mamiriro, zvisinei, pasi peiyo makabati anofanirwawo kuyedzwa. Makabati ekuchengetedza zvipenyu anofanirwa kupihwa zvitupa rinhi panguva iyi? Kazhinji, ivo vanofanirwa kuongororwa mushure mechiitiko chipi nechipi chinogona kukanganisa mamiriro kana kushanda kwemidziyo: kugadzirisa kukuru, tsaona, kutsiva HEPA mafirita, zvishandiso kana kutamiswa kwenzvimbo, uye mushure menguva yekuvharika kwakawedzerwa, semuenzaniso.
Mhute yakanaka ye potassium iodide droplets, inogadzirwa ne spinning disk, inoshandiswa sechinhu chinonetsa aerosol kuyera kuvharwa kwebiosafety cabinet. Pakupera kwenguva yesampling mamembres esefa anoiswa mumushonga wepalladium chloride apo iyo potassium iodide "inokura" kuti iite zvinonyatsooneka uye zvinoonekwa zviri nyore grey/brown dots.
Zvinoenderana ne EN 12469: 2000 Apf (cabinet protection factor) inofanirwa kunge isingasviki zviuru zana pamuunganidzi wega wega kana kuti hapafanirwe kuve neanopfuura makumi matanhatu nemaviri madotsi ebrown paKI discus sefa membrane mushure mekuvandudzwa mupalladium chloride.
Biological kuchengetedza kabati kuyedzwa uye chitupa kunosanganisira akati wandei bvunzo, imwe inodiwa uye imwe sarudzo, zvichienderana nezvinangwa zvekuyedzwa uye zviyero zvinofanirwa kuzadzikiswa.
Inodiwa certification bvunzo dzinowanzo sanganisira:
1, Inflow velocity kuyerwa: Inoyera mafambiro emhepo pachiso cheyuniti kuti ive nechokwadi chekuti zvinhu zvine biohazardous hazvipukunyuke mukhabhineti kwazvinozoisa njodzi kune anoshanda kana marabhoritari nenzvimbo yenzvimbo.
2, Downflow velocity zviyero: Inovimbisa kuti kuyerera kwemhepo mukati menzvimbo yebasa yekabati iri kushanda sezvakarongwa uye haisi kuyambuka kusvibisa nzvimbo yebasa mukati mekhabhineti.
3, HEPA sefa yekuyera kutendeseka kuyedzwa: Inotarisisa iyo HEPA sefa kutendeseka nekuona chero kuvuza, hurema, kana kuti bypass kuvuza.
4, Kuyedzwa kwechiutsi: Inoshandisa svikiro inooneka kuona uye kuona kwakakodzera mafambiro emhepo uye midziyo.
5,Kuyedzwa kwekumisikidzwa kwesaiti: Inovimbisa kuti mayunitsi akaiswa zvakanaka mukati meiyo nzvimbo zvinoenderana neNSF uye OSHA zviyero.
6,Alarm calibration: Inosimbisa kuti maaramu ekuyerera kwemhepo akaiswa zvakanaka kuratidza chero mamiriro asina kuchengetedzeka.
1, Kuverengera kusingagoneke kwechikamu - nechinangwa cheiyo ISO kupatsanura nzvimbo, kazhinji kana kuchengetedzwa kwemurwere kuri kunetseka.
2, UV mwenje yekuyedza - kupa µW/cm² kubuda kwemwenje kuti uverenge yakakodzera kuratidzwa nguva zvichienderana nezvinosvibisa zviripo. Chinodiwa cheOSHA kana UV mwenje uchishandiswa kubvisa tsvina.
3,Kuyedzwa kwekuchengetedzwa kwemagetsi - kugadzirisa zvingangoita nyaya dzekuchengetedza magetsi pamayuniti asina kunyorwa UL
4,Fluorescent mwenje kuyedzwa, Vibration kuyedzwa, kana Inzwi kuyedza - kunyaradza kwevashandi uye bvunzo dzekuchengetedza dzinogona kuratidza kana mamwe maprotocol ekuchengetedza kana gadziriso achizodiwa.
Cleanroom yekuyedza zvinhu zvinosanganisira kusefa mhepo yekumhanyisa kufanana,sefa yekubuda kwekuona, kusiyana kwepressure,kufambisa kwemhepo kufanana,utsanana, ruzha, kuvhenekera, humidity/temperature, zvichingodaro.
