Umgangatho wesizwe we-GB/T 18801-2022
Umgangatho wesizwe we-GB/T 18801-2022 yakhutshwa ngo-Oc. 12, 2022, kwaye iya kuphunyezwa ngoMeyi 1, 2023, ithatha indawo ye-GB/T 18801-2015 . Ukukhutshwa komgangatho omtsha wesizwe kubeka phambili iimfuno eziphezulu zomgangatho wezicoci zomoya, kwaye kwakhona kudlala indima ebalulekileyo kuphuhliso loshishino lokucoca umoya kunye nokubekwa emgangathweni kwemveliso yamashishini anxulumeneyo. Oku kulandelayo kuya kuhlalutya utshintsho phakathi kwemigangatho yesizwe emidala kunye nentsha ukukunceda ukuba uqonde ngokukhawuleza ukuhlaziywa okuphambili kwemigangatho emitsha yesizwe.
Ukwandiswa kwendawo ekujoliswe kuyo kungcoliseko
Ungcoliseko ekujoliswe kulo luye lwatshintshwa lusuka kwinguqulelo ka-2015 “yezingcolisi zomoya ezikhethekileyo ezinokwakheka okucacileyo, ikakhulu zahlulwe zibe ziindidi ezintathu: i-particulate matter, i-gaseous pollunts kunye ne-microorganisms” ukuya kwinguqulelo ka-2022 “yezingcolisi zomoya ezithile ezinokwakheka okucacileyo, ikakhulu zahlulwe zibe ziinxalenye ezithile. izinto, izinto ezingcolisa igesi, iimicroorganisms, izinto eziguquguqukayo kunye namavumba".
Izalathi zokunxibelelanisa i-particulate matter kunye nezingcolisi zegesi
Nangona izinga lokuhanjiswa komoya ococekileyo (CADR) kunye nomthamo wokucoca okuqokelelweyo (CCM) zizalathisi ezibalulekileyo zokugweba ukusebenza kwemveliso, akukho lunxulumano phakathi kweemfuno zazo. Ngenxa yoko, iimveliso zezinye iinkampani zilandela ngokugqithisileyo amaxabiso okuqala aphezulu e-CADR, kodwa ubomi bazo bufutshane, bulahlekisa abathengi. Umgangatho omtsha wesizwe wonyusa unxulumano phakathi kwexabiso le-CADR ye-particle matter kunye nongcoliseko lwegesi kunye neenqobo ze-CCM. Ukusetyenziswa kwezalathisi zokulungelelanisa endaweni yendlela yokuvavanya ikhefu le-CCM kunye nokumiselwa komda omncinci we-CCM ngokobungakanani be-CADR iya kudlala indima engcono ekulawuleni imarike yokucoca umoya.
Indlela yokuvavanya izinga lokususwa kwentsholongwane
Ngenxa yobungcali bentsholongwane, izinga lokuphela kwentsholongwane yendalo kunye nenkqubo yokuhlanjululwa ayinakuchazwa yi-equation equilibrium equation yoxinaniso olungcolileyo, ngoko ke i-CADR ayinakusetyenziswa njengesalathiso sokuvavanya ukukwazi ukuhlanjululwa kwentsholongwane yokucoca umoya. Ngoko ke, kwisakhono sokucocwa kwentsholongwane, umgangatho ukwaphakamisa indlela yokuvavanya 'kwizinga lokususwa'. Ngexesha elifanayo, ngokweemfuno eziqhelekileyo, ukuba umcoci womoya ubonisa ngokucacileyo ukuba unomsebenzi wokususa intsholongwane, izinga lokususa intsholongwane phantsi kweemeko ezichaziweyo akufanele libe ngaphantsi kwe-99.9%.
Oku ngasentla kuluhlu nje olulula lwezihlaziyo ezintathu eziphambili zomgangatho omtsha wesizwe, ezihambelana ngokusisiseko nemo yemarike yangoku kwaye ikhokela ishishini ukuba liphuhlise ngokuthe ngcembe kwicala elinempilo.
