Mu Julayi 2020, chida cha nyenyezi, ZR-1006 Mask Particulate Filtration Efficiency ndi Air flow Resistance Tester.
Chiyambi cha Zamalonda
ZR-1006 mask particle kusefera bwino komanso kuyesa kukana kwa airflow idapangidwa payokha ndikupangidwa ndi Qingdao Junray. Amagwiritsidwa ntchito kuyesa kusefera moyenera malinga ndi miyezo yapakhomo ndi yakunja ya masks. Izi zimagwiritsa ntchito ma module ojambulidwa kunja ndikupangidwa mokhazikika ndikupangidwa ndi aerosol photometer, ndikukhala ndi mchere (NaCl) ndi mafuta (parafini mafuta) jenereta ya aerosol. Timapereka zoyezera zoyezera bwino kwambiri za particulate kusefa komanso mayankho amunthu payekha pamasukulu owunikira zabwino, masukulu owunikira ma fiber, malo owunikira zida zachipatala, anthu ena ndi opanga chigoba komanso opanga nsalu zosungunula.
Ubwino wa mankhwala
1. Kutsatira kwapamwamba
ZR-1006 imagwiritsa ntchito njira yoyesera mafotomita awiri a mitsinje, yomwe imatha kuzindikira ndendende kuchuluka kwa aerosol ya mitsinje iwiri, ndipo imatha kuyesa kuyesa kangapo, kuyesako kumagwirizana ndi zomwe zili m'nyumba ndi zakunja (tebulo 1).

Miyezo ya chigoba padziko lonse lapansi (tebulo 1)
Zindikirani:
1. Kukana kwa Airflow ndi kwa GB 19083 yokha
2. Zida zina zimatengera mfundo ya tinthu tating'onoting'ono sitingathe kuzindikira ndende ya anthu ambiri kapena kuyesa kuyesa, kotero zida zamtunduwu sizigwirizana ndi miyezo.
2. Kuchita kwa chidacho kumakhala kokhazikika.
2.1Kuzindikira kwa Photometer ndikolondola kwambiri:Photometer yodziyimira payokha yomwe idafufuzidwa ndikupangidwa imatengera gawo la electro-optic module, mayeso ndi 0.001mg/m³-100mg/m³, kusamvana ndi 0.001 mg/m³.
2.2.Kubwereza kwabwino: Kuyesedwa kolondola kwa ZR-1006 ndi 1%, kubwereza ndi 2%.
2.3.Kulephera kochepa: ZR-1006 imatengera kapangidwe kagawidwe ndi zinthu zapamwamba kwambiri komanso kapangidwe kabwino kamangidwe, komanso kukhathamiritsa kwakuya pamapulogalamu, zonse pamwambapa zimatsimikizira kulephera mkati mwa 10%.
3.Kuchita bwino
3.1Yabwino ntchito mawonekedwe: Imayendetsedwa ndi chinsalu chojambula chamitundu, magawo ofananira amatha kulowetsedwa ndi zotsatira zoyesa.
3.2Njira yoyesera ndiyosavuta : Kuyesa kosalekeza pambuyo pa nthawi imodzi ya kusintha kwa ndende ya aerosol. Zokhala ndi ma clamps osiyanasiyana, masks ndi nsalu zosungunula zitha kuyesedwa ndikuyika pachipinda choyesera mwachindunji. Kutumiza ndi kujambula zotsatira zodziwikiratu, ndikuzisindikiza ndi chosindikizira cha Bluetooth.
3.3 Njira zingapo zoyesera:Ogwiritsa ntchito amatha kusankha mitundu yoyesera-nthawi yoyezetsa kapena kutsitsa mayeso malinga ndi mayeso azinthu, chidacho chimayesa kuyesa pambuyo poyika zomwe zikufunika, zotsatira zoyeserera zotumiza kunja.
4. Pambuyo pa ntchito yogulitsa
Qingdao Junray adapereka 1 ~ 2 pambuyo pa ogwira ntchito ogulitsa kumizinda ikuluikulu ku China, azindikire zomwe zimachitika nthawi iliyonse ndikupereka khomo lokhazikitsa ndi kuphunzitsa komanso pambuyo pokonza zogulitsa; Kupatula apo, a Junray ali ndi kampani yakuya yokhala ndi akatswiri othandizira zida, kasitomala wakunja atha kupeza akatswiri pambuyo pogulitsa kuchokera kwa othandizira.
Lipoti la miyeso
Shanghai Institute of Measurement and Testing Technology ndiye malo otchuka kwambiri oyezera mafotomita aerosol ndi kuyeza kukula kwa aerosol, njira zake komanso kulondola kwake ndizomwe zili patsogolo ku China. Mu July 2020, ndi mgwirizano wa makasitomala athu, ZR-1000 kuyeza otaya, aerosol photometer, kukana ndi kukula mafuta ndi mchere aerosols, zotsatira zonse zikugwirizana ndi zofunika muyezo, zomwe zimapangitsa kukhala particulate kusefera Mwachangu tester amene magawo onse. amaperekedwa ndi kuyeneretsedwa.
