Maitiro ekunyatso kuyedza uye kuchengetedza yako yekuchenesa kamuri yemhando

Kuongororwa kwemukamuri yekuchenesa kwakakosha kuti uve nechokwadi chekutevedzwa, kuchengetedza mhando yechigadzirwa, kuchengetedza maitiro akajeka, kuchengetedza hutano nekuchengetedzeka, kugadzirisa mashandiro, kuchengetedza mari, uye kuvaka chivimbo chevatengi. Kugara uye kuyedzwa kwakaringana kunobatsira kuve nechokwadi chekuti imba yako yekuchenesa inoramba iine hutsanana hwakasimba uye mitemo yekudzora kwezvakatipoteredza, pakupedzisira ichitsigira kubudirira uye kutendeseka kwemabasa ako.

Kuyedza imba yako yekuchenesa zvinoenderana neISO 14644 kunosanganisira akati wandei matanho ekuona kuti inosangana neinodiwa particle count allowances pakurongwa kwayo. Heino gwara rakazara.

1. Nzwisisa ISO 14644 Mitemo

TS EN ISO 14644-1: Inotsanangura kurongeka kwehutsanana hwemhepo nechikamu chemukati.

ISO 14644-2: Inotsanangura yekutarisa kuratidza kuenderera mberi kutevedzera ISO 14644-1.

2. Kugadzirira Kuongororwa

Sarudza Kucheneswa Kwekamuri: Ziva iyo chaiyo ISO kupatsanura (semuenzaniso, ISO Kirasi 5) inoshanda mukamuri yako yekuchenesa.

Gadzira Nzvimbo dzeSampling: Zvinoenderana nehukuru hwekamuri yekuchenesa uye kurongeka, tarisa huwandu uye zvinzvimbo zvemasampling point.

3. Sarudza uye Calibrate Equipment

Particle Counter: Shandisa yakagadziriswa uye yakasimbiswa particle counter inokwanisa kuyera inodiwa particle size (semuenzaniso, ≥0.1 µm kana ≥0.3 µm).

Calibration Cheki: Ita shuwa kuti iyo particle counter yakagadziriswa sekurudziro yemugadziri kuti avimbise zviyero zvakaringana.

4. Gadzira Nzvimbo dzeSampling

Nhamba Yenzvimbo dzeSampling: Tarisa kune ISO 14644-1, iyo inopa nhungamiro pahuwandu hwemasampling poindi zvichienderana nenzvimbo yekuchenesa. Tarisa tafura A.1 muyero.

Kune dzimba dzakakura dzakachena uye dzakachena nzvimbo (＞1000㎡), shandisa inotevera fomula kuverenga nzvimbo shoma dzesampling.

N_Lndiyo ishoma nhamba yenzvimbo dzesampling dzinoongororwa, dzichitenderedzwa kusvika panhamba yese inotevera.

A inzvimbo yekuchenesa mum².

Maka Sampling Points: Maka pachena nzvimbo dziri mukati meimba yekuchenesa umo masampuli achatorwa.

5. Gadzira imwe sampuli vhoriyamu pane imwe nzvimbo

Shandisa fomula inotevera kuverenga vhoriyamu yemuenzaniso.

Vsndiyo shoma shoma vhoriyamu imwe chete yemuenzaniso panzvimbo imwe neimwe, inoratidzwa mumarita;

C_n,mndiwo muganho wekirasi (nhamba yezvimedu pa cubic metre) yehukuru hwakafungidzirwa saizi yechikamu chakatsanangurwa kukirasi yakakodzera.

20inhamba yezvimedu zvaigona kuverengwa kana particle concentration yaiva pamuganhu wekirasi.

6. Ita Muedzo

   Mema Particle Counts: Pane imwe neimwe nzvimbo yekuyedza, shandisa iyo particle counter kuyera kusangana kwezvimedu zvinofambiswa nemhepo.

   Nzira yekuyera:

Sample yenguva yakatarwa panzvimbo imwe neimwe.

Rekodha nhamba yezvimedu zvehukuru hwakasiyana.

Sample Replication: Ita zviyero zvakawanda panzvimbo yega yega kuti uzvidavirire pakusiyana uye simbisa kuenderana.

7. Data Analysis uye Kuenzanisa

Ongorora Dhata: Enzanisa iyo yakarekodhwa particle counts inopesana nemiganho yakatsanangurwa muISO 14644-1 yekirasi yekuchenesa kirasi.

Maitiro ekugamuchira: Ita shuwa kuti chikamu chinoverengera kune yega yega nzvimbo uye saizi renji haipfuure iyo inobvumidzwa miganhu.

8. Zvinyorwa

     Gadzirira Chirevo: Nyora maitiro ese ekuyedza, kusanganisira:

a. zita nekero yesangano rekuedza, uye zuva rakaitwa bvunzo.

b. nhamba negore rekuburitswa kwechikamu ichi che ISO 14644, kureva ISO 14644-1:2015

c. chiziviso chakajeka chenzvimbo chaiyo yeimba yekuchenesa kana nzvimbo yakachena yakaedzwa (kusanganisira kunongedzera kunzvimbo dziri padyo kana zvichidikanwa),

uye mazita chaiwo ezvirongwa zvesampling yese)

d. iyo yakatsanangurwa yekudoma nzira yeimba yakachena kana nzvimbo yakachena, kusanganisira iyo ISO Kirasi nhamba, yakakodzera nzvimbo yekugara, uye

zvakafungwaparticle size(s).

e. ruzivo rwenzira yekuyedza yakashandiswa, iine chero akakosha mamiriro ane chekuita nebvunzo, kana mabviro kubva muyedzo nzira, uye kuzivikanwa kweiyo bvunzo.

testchiridzwa uye chitupa chazvino che calibration, uye mhinduro dzebvunzo, zvinosanganisira particle concentration data yenzvimbo dzese dzesampling.

9. Kero Deviations

Ongorora Kwakabva: Kana chero chidimbu chiverengera chakapfuura miganhu inotenderwa, tsvaga zvingangove zvipi zvinosvibisa.

Kururamisa Zviito: Shandisa matanho ekugadzirisa, akadai sekuvandudza kusefa kana kuona uye kudzikisira masosi enyaya.

10. Kuramba Kuongorora

Kuongororwa Kwenguva Dzose: Gadzira chirongwa chenguva dzose chekuyedza (mwedzi mitanhatu yega yega kusvika gumi nemiviri) kuti uve nechokwadi chekuenderera mberi kwekutevedzera ISO zviyero.

Environmental Monitoring: Ramba uchitarisa mamwe maparamendi ezvakatipoteredza senge tembiricha, humidity, uye musiyano wekumanikidza kuchengetedza.
