Laminar flow cabinet, yomwe imatchedwanso benchi yoyera, ndi zida zoyeretsera zapanyumba zomwe zimagwiritsidwa ntchito ndi antchito. Itha kupanga malo am'deralo okhala ndi ukhondo wapamwamba. Ndi yabwino kwa kafukufuku wa sayansi, mankhwala, mankhwala ndi thanzi, zida zamagetsi zamagetsi ndi mafakitale ena. zida. Laminar flow cabinet imathanso kulumikizidwa mumzere wopanga msonkhano ndi zabwino zaphokoso lotsika komanso kuyenda. Ndi zida zosunthika kwambiri zoyeretsa mpweya zomwe zimapereka malo ogwirira ntchito aukhondo kwambiri. Kugwiritsiridwa ntchito kwake kumakhala ndi zotsatira zabwino pakuwongolera zochitika, kupititsa patsogolo khalidwe la mankhwala ndi kuwonjezeka kwa zokolola.
Ubwino wa benchi yoyera ndikuti ndi yosavuta kugwiritsa ntchito, yomasuka, yothandiza, komanso imakhala ndi nthawi yochepa yokonzekera. Itha kugwiritsidwa ntchito pakadutsa mphindi 10 mutayamba, ndipo imatha kugwiritsidwa ntchito nthawi iliyonse. Popanga zopangira zaukhondo, pamene ntchito ya katemera ndi yayikulu kwambiri ndipo katemera amafunika kuchitidwa pafupipafupi komanso kwa nthawi yayitali, benchi yoyera ndi zida zoyenera.
Benchi yoyera imayendetsedwa ndi mota yamagawo atatu yokhala ndi mphamvu pafupifupi 145 mpaka 260W. Mpweya umawulutsidwa kudzera pa "super fyuluta" yopangidwa ndi zigawo za mapepala apadera a thovu a microporous kuti apange malo opanda fumbi mosalekeza. Wosabala laminar otaya mpweya woyera, otchedwa "wogwira wapadera mpweya", amachotsa fumbi, bowa ndi spores bakiteriya zazikulu kuposa 0,3μm, etc.
Kuthamanga kwa mpweya wa ultra-clean workbench ndi 24-30m / min, zomwe zimakhala zokwanira kuteteza kuipitsa komwe kumachitika chifukwa cha kusokonezeka kwa mpweya wapafupi. Kuthamanga kumeneku sikungalepheretse kugwiritsa ntchito nyale za mowa kapena zoyatsira za bunsen kuwotcha ndi kupha zida.
Ogwira ntchitowa amagwira ntchito pansi pazifukwa zotere kuti zinthu zosabala zisaipitsidwe panthawi yakusamutsa ndi kuponderezedwa. Koma pamene mphamvu yazimitsidwa pakati pa ntchito, zipangizo zomwe zimawululidwa ndi mpweya wosasefedwa sizidzatetezedwa ku kuipitsidwa.
Panthawiyi, ntchitoyo iyenera kumalizidwa mwamsanga ndipo chizindikiro chiyenera kupangidwa pa botolo. Ngati zinthu zamkati zili mu gawo la kufalikira, sizidzagwiritsidwanso ntchito kuchulukitsa ndipo zidzasamutsidwa ku chikhalidwe cha rooting. Ngati ndi zinthu zopangira wamba, zitha kutayidwa ngati zili zochuluka kwambiri. Ngati wazika mizu, ukhoza kusungidwa kuti udzabzalidwe mtsogolo.
Mphamvu ya mabenchi oyera nthawi zambiri imagwiritsa ntchito mawaya atatu a magawo anayi, pomwe pali waya wosalowerera, womwe umalumikizidwa ndi chipolopolo cha makina ndipo uyenera kulumikizidwa mwamphamvu ndi waya wapansi. Mawaya ena atatu onse ndi mawaya agawo, ndipo mphamvu yogwira ntchito ndi 380V. Pali kutsatizana kwina mu mawaya atatu. Ngati malekezero a waya alumikizidwa molakwika, faniyo idzasintha, ndipo phokoso lidzakhala lachilendo kapena lachilendo pang'ono. Palibe mphepo kutsogolo kwa benchi yoyera (mutha kugwiritsa ntchito nyali ya mowa kuti muwone kayendetsedwe kake, ndipo sikoyenera kuyesa kwa nthawi yaitali). Dulani magetsi mu nthawi, ndipo ingosinthani malo a mawaya amtundu uliwonse ndikugwirizanitsanso, ndipo vutoli likhoza kuthetsedwa.
Ngati magawo awiri okha a mzere wa magawo atatu alumikizidwa, kapena ngati gawo limodzi mwa magawo atatuwo sililumikizana bwino, makinawo amamveka ngati achilendo. Muyenera kudula magetsi nthawi yomweyo ndikuwunika mosamala, apo ayi injiniyo idzawotchedwa. Kuganiza bwino kumeneku kuyenera kufotokozedwa momveka bwino kwa ogwira ntchito pamene ayamba kugwiritsa ntchito benchi yoyera kuti apewe ngozi ndi zotayika.
Mpweya wolowera pa benchi yoyera uli kumbuyo kapena pansi kutsogolo. Muli pepala la pulasitiki la thovu wamba kapena nsalu yosalukidwa mkati mwa chivundikiro cha ma mesh chachitsulo kuti atseke tinthu tambiri ta fumbi. Iyenera kufufuzidwa pafupipafupi, kuswa ndikutsukidwa. Ngati pulasitiki wa thovu ndi wokalamba, m'malo mwa nthawi.
Kupatula polowera mpweya, ngati pali mabowo kutayikira mpweya, ayenera oletsedwa mwamphamvu, monga kugwiritsa ntchito tepi, stuffing thonje, kugwiritsa ntchito guluu pepala, etc. The wapamwamba fyuluta angathenso m'malo. Ngati yakhala ikugwiritsidwa ntchito kwa nthawi yayitali, tinthu tating'ono ta fumbi timatsekedwa, kuthamanga kwa mphepo kumachepetsedwa, ndipo ntchito yosabala sichingatsimikizidwe, ikhoza kusinthidwa ndi yatsopano.
Moyo wautumiki wa benchi yoyera umagwirizana ndi ukhondo wa mpweya. M'madera otentha, mabenchi oyeretsedwa kwambiri amatha kugwiritsidwa ntchito m'ma laboratories wamba. Komabe, m'madera otentha kapena otentha, kumene mpweya uli ndi mungu wambiri kapena fumbi, benchi yoyera iyenera kuikidwa m'nyumba yokhala ndi zitseko ziwiri. . Nthawi zonse hood yolowera mpweya ya benchi yoyera isayang'ane ndi khomo lotseguka kapena zenera kuti zipewe kusokoneza moyo wa ntchito ya fyuluta.
Chipinda chosabala chiyenera kupopera mowa wa 70% kapena 0.5% phenol kuti muchepetse fumbi ndi mankhwala ophera tizilombo, pukutani ma countertops ndi ziwiya ndi 2% neogerazine (70% mowa ndi wovomerezeka), ndikugwiritsanso ntchito formalin (40% formaldehyde) kuphatikiza pang'ono. kuchuluka kwa permanganic acid. Potaziyamu amasindikizidwa nthawi zonse ndikufukizidwa, kuphatikiza njira zophera tizilombo toyambitsa matenda ndi njira zotsekera monga nyali za ultraviolet zoletsa (kuyaka kwa mphindi zopitilira 15 nthawi iliyonse), kotero kuti chipinda chopanda kanthu chikhoza kukhalabe cholimba kwambiri.
Mkati mwa bokosi la inoculation muyeneranso kukhala ndi nyali ya ultraviolet. Yatsani nyali kwa mphindi zopitilira 15 musanagwiritse ntchito kuti muziziritsa ndi kuthirira. Komabe, malo aliwonse omwe sangathe kuyatsa amadzazabe ndi mabakiteriya.
Nyali ya ultraviolet ikayatsidwa kwa nthawi yayitali, imatha kulimbikitsa mamolekyu a okosijeni omwe ali mumlengalenga kuti agwirizane ndi mamolekyu a ozone. Mpweya umenewu umakhala ndi mphamvu yophera tizilombo toyambitsa matenda ndipo umatha kuchititsa nthiti pamakona omwe sawunikiridwa mwachindunji ndi cheza cha ultraviolet. Popeza ozoni ndi yovulaza thanzi, muyenera kuzimitsa nyali ya ultraviolet musanalowe mu opaleshoni, ndipo mukhoza kulowa pambuyo pa mphindi zoposa khumi.
