Umahluko phakathi kwe-EN877:2021 kunye ne-EN877:2006

Umgangatho we-EN877 uchaza iimfuno zokusebenza kweimibhobho yesinyithi esenziwe ngentsimbi, izixhobo zokufakelwakwayeizihlanganisi zaboisetyenziswa kwiinkqubo zokukhupha amanzi amdaka kwizakhiwo.EN877:2021yinguqulelo yamva nje yomgangatho, ithatha indawo yenguqulelo yangaphambili ye-EN877:2006. Umahluko ophambili phakathi kwezi nguqulelo zimbini ngokwemivavanyo zezi zilandelayo:

1. Ububanzi bovavanyo:

EN877:2006: Ngokuyintloko ivavanya iimpawu zoomatshini kunye neempawu zokutywina zemibhobho kunye nezixhobo.

EN877:2021: Ngokusekelwe kuvavanyo lokuqala, kongezwe iimfuno zovavanyo zokusebenza kokuthintela isandi, ukumelana nokugqwala kweekhemikhali, ukumelana nomlilo kunye nezinye izinto zenkqubo yemibhobho.

2. Iindlela zovavanyo:

I-EN877:2021 ihlaziya ezinye iindlela zovavanyo ukuze zizenze zibe zenzululwazi kwaye zibe nengqiqo ngakumbi, ezinje:Uvavanyo lokuxhathisa ukugqwala ngamakhemikhali: Kusetyenziswa izisombululo ezintsha zovavanyo kunye neendlela zovavanyo, njengokusebenzisa isisombululo se-pH2 sulfuric acid endaweni yesisombululo sokuqala se-hydrochloric acid, kunye nokongeza iimvavanyo zokuxhathisa ukugqwala kwiikhemikhali ezingaphezulu.

Uvavanyo lokusebenza kwe-acoustic: Iimfuneko zovavanyo ezongezelelweyo zokusebenza kwe-insulation yesandi kwinkqubo yepayipi, njengokusebenzisa indlela yenqanaba loxinzelelo lwesandi ukulinganisa i-insulation yesandi kwinkqubo yepayipi.

Uvavanyo lokusebenza komlilo: Iimfuneko zovavanyo ezongezelelweyo zokusebenza kokumelana nomlilo kwenkqubo yemibhobho, njengokusebenzisa indlela yokunciphisa ukumelana nomlilo ukuvavanya ukuthembeka kwenkqubo yemibhobho phantsi kweemeko zomlilo.I-EN877:2021 isebenzisa ipeyinti enomgangatho A1 okumelana nomlilo

3. Iimfuno zovavanyo:

I-EN877:2021 yonyusile iimfuno zovavanyo kwezinye izalathisi zokusebenza, ezinje:Amandla okutsalwa: anyuswe ukusuka kwi-150 MPa ukuya kwi-200 MPa.
Ukwandiswa: kunyuke ukusuka kwi-1% ukuya kwi-2%.

Ukumelana nokugqwala kweekhemikhali: Iimfuneko zokumelana nokugqwala ezongezelelweyo kwizinto ezininzi zeekhemikhali, ezifana neemfuno zokumelana nokugqwala kwizinto ze-alkaline ezifana ne-sodium hydroxide kunye ne-potassium hydroxide.

4. Ingxelo yovavanyo:

I-EN877:2021 ineemfuno ezingqongqo malunga nomxholo kunye nefomathi yengxelo yovavanyo, ezinje:Ifuna ingxelo yovavanyo ibandakanye ulwazi oluneenkcukacha ezifana neendlela zovavanyo, iimeko zovavanyo, iziphumo zovavanyo, kunye nezigqibo.

Ingxelo yovavanyo kufuneka ikhutshwe yiarhente yovavanyo efanelekileyo. Umzekelo,I-DINSEN iqinisekiswe yi-CASTCO.
Umgangatho we-EN877:2021 ubanzi kwaye ungqongqo xa uvavanywa kunomgangatho we-EN877:2006, obonisa uphuhliso lwamva nje lwetekhnoloji kunye neemfuno zemarike kushishino lwemibhobho yesinyithi. Ukuphunyezwa komgangatho omtsha kuya kunceda ukuphucula umgangatho weemveliso zemibhobho yesinyithi kwaye kukhuthaze ukhuseleko kunye nokuthembeka kweenkqubo zokuhambisa amanzi ezakhiweyo.
