Mhedzisiro yeformaldehyde haisi yebhodhi. Inobuda kubva muchikamu chinodzorwa — sample, seal, load, condition, sample air, analysis — uye nhanho yega yega inogona kufambisa nhamba yekupedzisira.
Chinyorwa chino chinotevera rimwe boka kuburikidza neKamuri remamiriro ekunze re 1 m³mhanya, uchitevedzana nemaitiro anoitwa nerabhoritari, uye wonyora kuti kutevedzana kwacho kunowanzo kanganiswa papi.
Zvinhu zvinokosha zvekudzidza
- Kamuri rinoyera kubuda kwemhepo pasi pemamiriro ezvinhu akatsanangurwa, robva raita kuti iite seyakajairika nenzvimbo - bhodhi harimboedzwa "sezvariri".
- Chinhu chinopa mutoro pamwe chete nemhepo zvinosarudza huwandu hwemhepo; shanduko imwe neimwe uye mhedzisiro yacho haienzaniswi.
- Kuvhara madziro emupendero ndiyo nzira inonyanya kukonzera mhedzisiro yakakwidibira.
- Mhedzisiro yacho inoshanda chete kana yakamira zvakanaka, kwete pakutanga kwekutora sampuli.
SeiKamuri re 1 m³, kwete imba chaiyo
Kamuri chaiyo haidzokororwi: huwandu hunosiyana, mhepo inofefetera inosiyana, uye hapana makamuri maviri ane huwandu hwakafanana hwefenicha. Kamuri inochinjana reality nekutonga, uye kurasikirwa kunodzokororwa nechiyero chakatsanangurwa.
Chiyero ichocho ndicho chinhu chinorema — mativi mana emamita ebhodhi rakavhurika pa cubic mita imwe neimwe yemhepo yemukamuri. Munzira ye 1 m³ pasi pe GB 18580, inowanzova 1 m²/m³, izvo zvinoita kuti mhedzisiro yebhenji iwedzererwe mukamuri rehukuru chero hupi zvahwo.
Fizikisi iri nyore kunyora. Pakuenzana, huwandu hwezvinhu hwakaenzana nehuwandu hwemhepo inobuda munzvimbo yawanikwe huchiwedzerwa nechinhu chinoiswa uye huchikamurwa nehuwandu hwemhepo inochinjana. Paramita yega yega iri muchikamu chekamuri iripo kuti ichengetedze rimwe remashoko iwayo risingachinji.
Danho 1 — Ronga sampuli usati wapinda
Mapaneru anoenzaniswa patembiricha yakarongwa uye hunyoro usati waedza, saka hunyoro hwepamusoro hunenge hwava padanho rinozivikanwa. Bhodhi rinotorwa kubva mudura rine hunyoro hunochinja hunyoro hwemhepo inobuda nekukurumidza.
Pamapuranga epasi nemapaneru akagadzirwa neunyanzvi, danho iri rekugadzirisa zvinhu ndipo panochekwawo muenzaniso panzvimbo yakatarwa — uye mipendero yekucheka ndiyo dambudziko rinoda kugadziriswa nedanho rinotevera.
Danho rechipiri — Vhara mipendero
Kuvhara mucheto kunodzivirira kubuda kwechinhu chinoshongedza, saka mhedzisiro yacho inotsanangura chigadzirwa sechakaiswa kwete chigadzirwa sechakachekwa. Tepi yealuminium foil ndiyo nzira yakajairika, uye inofanira kunge yakakwana.
Mupendero usina kuvharwa kana kuti wakavharwa zvishoma unoburitsa zvinhu zvitsva zvemukati, izvo zvinoburitsa zvinopfuura nzvimbo yakatarisana. Mugumisiro wacho unoratidza nhamba inogoneka inokundikana pakuedzwazve - uye bvunzo yekudzokorora inowanzo pomerwa mhosva yekamuri.
Danho rechitatu — Rodha wovhara
Mienzaniso yakavharwa inoiswa pachigadziko mukati mekamuri, yakakamurwa kuitira kuti mhepo ifambe-fambe kumeso ese ari maviri. Kutakura kunoverengerwa kubva panzvimbo yakavhurika, kwete kubva pahuremu, ndosaka ukobvu hwepepa husingapindi mukuverenga asi huwandu hwebhodhi hunopindirwa.
Kana yavharwa, imba inochengeta nzvimbo dzayo dzakatarwa: tembiricha nehunyoro pamitengo yakanyorwa muchiyero, uye mwero wekuchinjana kwemhepo unochengetwa nemagetsi anodzorwa nehukuru hwemvura uye utsi.
Danho rechina — Ratidza kuti imba yakachena
Usati watanga kutsvaira, kuongorora kusina chinhu kunoratidza huwandu hwemvura iri kumashure. Makamuri anosveta uye anozoburitsa formaldehyde; kamuri rinotaridzika rakachena rakapedzisira kushandiswa pakutsvaga mvura yakawanda rinogona kutakura tsvina mumhedzisiro inotevera.
Apa ndipo panoonekwawo kuti kudzoserwa kwemvura kwacho kunoonekwa — kugona kwechikamu chekuongorora sampuli kubata nekuverenga huwandu hunozivikanwa. Pasina izvozvo, kuverenga kwakaderera kunogona kureva bhodhi rine hutsi hushoma kana mutsetse wekuongorora sampuli unodonhedza mvura, uye zviviri izvi hazvisiyaniswi.
Danho 5 — Muenzaniso kusvika wagadzikana
Kubuda kwemhepo kunoora sezvo chikamu chepamusoro chichiderera, saka huwandu hwemvura hunokwira, hunokwira uye hunozogara pasi. Kutora sampuli kunowanzo tanga mushure menguva yekutanga yakatsanangurwa munzira uye kunoenderera mberi zuva nezuva kusvika mamiriro akadzikama aratidzwa - sezvakajairika, mhedzisiro miviri inotevedzana inobvumirana mukati mechikamu chidiki.
Saka kuyera kamwe chete kwekutanga hakusi mhedzisiro. Ipfungwa yedata iri munzira yekuenda kune imwe, uye kutaura nezvazvo semhinduro ndeimwe yezvikanganiso zvakajairika mumagwaro evatengesi.
Danho 6 — Ongorora uye tonga
Sampuli dzemhepo dzinotorwa kuburikidza nescrubber kana DNPH cartridge uye dzinoyerwa nenzira yeacetylacetone kana neHPLC. Dzese dzinogamuchirwa; dzese dzinoda calibration uye dzisina chinhu panguva imwe chete nesamples.
Kukosha kwekupedzisira kunoenzaniswa nemuganho uri muchiyero chinoshanda — paGB 18580 muganho weE1 i0.124 mg/m³ — uye mushumo unofanirwa kutaura chinhu chinorema, mwero wekutsinhana kwemhepo, tembiricha, hunyoro, mazuva ekutora sampuli uye nzira yekuongorora pamwe chete nazvo.
Mapoinzi akatarwa, purogiramu yekutora sampling uye miganhu yezvinodiwa zvinotsanangurwa muchinyorwa chazvino chechiyero chimwe nechimwe uye zvinogadziriswa nguva nenguva. Zvisimbise zvichienderana nechinyorwa chataurwa mufaira rako rehunyanzvi usati waburitsa chikumbiro.
Kwakawanzo tyoka cheni
- Kuvhara mucheto kusina kukwana— chikonzero chinowanzoitika chemhedzisiro chisingakwanise kudzokororwa.
- Mwero wekutsinhana kwemhepo inodonha— sefa rinozadzwa kwemwedzi yakawanda rinochinja dhinominator chinyararire, uye chikanganiso chinoita sekuchinja kwechigadzirwa.
- Kusagadzikana kwekupisa— kuburitswa kwemhepo kunoenderana zvakanyanya nekupisa, uye chikamu chidiki chedhigirii chinochengetwa kwemazuva akawanda hachina kukosha kupfuura rwendo rukuru rwenguva pfupi.
- Kushuma pasina mamiriro ezvinhu— nhamba isina chinhu chinopa mutoro, hapana mwero wekuchinja kwemhepo uye hapana zuva rekutora sampuli haisi mhinduro yekuedzwa.
Zvekutaura mukamuri
Zvinhu zvina zvinoparadzanisa kamuri rinogona kutsigira kuzivisa kubva kune iro rinogona kuburitsa nhamba chete:
- Mapoinzi akabatwa— tembiricha, hunyoro uye mwero wekutsinhana kwemhepo zvinodzorwa uye zvakanyorwa, kwete kungoratidzwa chete.
- Kudzora kuchinjana kwemhepo kunoteverwa— Kuyerwa kwehuwandu hwemvura inoyerera pahuwandu hwemvura inobuda uye inobuda, nerekodhi pakumhanya kwese.
- Mukati munocheneswa uye musingapindi mvura yakawanda— nzvimbo dzisina ngura uye maitiro asina chinhu akanyorwa.
- Nzvimbo dzekutora sampuli dzakaiswa kuti dziratidzike, uye nzira yekutora sampuli yakabatanidzwa pane kungofungidzirwa.

Mibvunzo inowanzo bvunzwa
Kuongororwa kwekamuri re1 m³ kunotora nguva yakareba sei?
Mazuva, kwete maawa. Kugadzirisa, kurodha, kudzikamisa uye kutora sampuli zuva nezuva kuti dzive dzakagadzikana zvinowanzotora vhiki imwe kusvika mbiri, uye purogiramu inofanira kurongwa maererano neizvozvo pane kumanikidzwa.
Ko kamuri rimwe chete rinogona here kuyedza mhando dzakasiyana dzemabhodhi?
Ehe, chero bedzi pasina chinhu uye gwaro rekuchenesa rakanyorwa rakaitwa pakati pezvigadzirwa. Kusanganiswa kwemvura inobuda zvakanyanya neyakasviba zvishoma ndiyo njodzi huru.
Sei paine hunyoro hwe23°C uye hunyoro hwe45%?
Nekuti dzinofungidzira mamiriro ezvinhu akajairwa emumba asi dzakasimba zvakakwana kudzora. Hutsi hunokwira zvakanyanya nekupisa, uye hunyoro hunokanganisa hydrolysis ye resin, saka zvese zvinogadziriswa nenzira iyi pane kusarudzwa nerabhoritari.
Mhedzisiro yenzira yekubvisa dhayi yakafanana here?
Kwete. Nzira yekubvisa dhayi ibvunzo yakasiyana ine hukama hwakasiyana, uye mhedzisiro haichinjiki nemitengo yekamuri. Taura nzira yacho, kwete nhamba chete.
