Ukuqaliswa kwe-mask synthetic yokuvavanya ukungena kwegazi ISO 22609-2004

Iimpawu eziphambili zovavanyo lwemaski yezonyango zokwenziwa kwegazi:

1. Isixhobo sokulungisa isampula esikhuphayo sinokufanisa imeko yokusetyenziswa kwangempela yemaski, ukushiya indawo ekujoliswe kuyo, kwaye ungonakalisi isampuli, kwaye wenze igazi lokwenziwa lihanjiswe kwindawo ekujoliswe kuyo isampuli.

2. Isixhobo esikhethekileyo sokutofa ngokucokisekileyo sinokutshiza umthamo othile wegazi lokwenziwa ngexesha elilawulwayo.

I-3, inokulinganisa ngokupheleleyo i-avareji yoxinzelelo lwegazi lomzimba womntu we-10.6kPa, 16kPa, 21.3kPa ehambelana nesantya sejethi sokuqhuba uvavanyo.

I-4, ipleyiti egxininisiweyo ejoliswe kuyo, inokuthintela uxinzelelo oluphezulu kunye nenxalenye ye-jet liquid flow flow, kuphela vumela indawo ezinzileyo yokuhamba kwejethi ukuya kwisampuli, ukwandisa ukuchaneka kunye nokuphindaphinda kwesantya se-jet liquid kwisampuli.

Umvavanyi wokungena kwegazi wemaski uyahlangabezana nemigangatho:

I-GB 19083-2010 Iimfuno zobuchwepheshe zeemaski zokhuselo lwezonyango, i-5.5 yokwenziwa komqobo wokungena kwegazi

Indlela yokuvavanya ukungena kwegazi lokwenziwa ngeemaski zonyango ukuze kukhuseleke kwiintsholongwane ezosulelayo (ivolumu emiselweyo, iJet eHorizontal)

YY 0469-2011 Iimaski zotyando zifuna izixhobo zovavanyo lokungena kwegazi

I-ISO 22609-2004 Iimaski zonyango zokhuseleko kwiintsholongwane ezosulelayo-Indlela yokuvavanya ukuchasana nokungena kwegazi elenziweyo (Umthamo oqingqiweyo, iJet eHorizontal)

I-ASTM F1862-07 Indlela yoVavanyo oluMiselweyo lokuNchasa iiMaski zoBuso bezoNyango ukuNgena ngeGazi eliFanelekileyo (Uqikelelo oluthe tyaba lweVolume eFixed kwi-Know Velocity)
