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

Umgangatho we-EN877 uxela iimfuno zokusebenza zeimibhobho yentsimbi, izixhobokwayeizihlanganisi zaboesetyenziswa kwiinkqubo zokukhupha amanzi omxhuzulane kwizakhiwo.EN877:2021yinguqulelo yamva nje yomgangatho, ithatha indawo ye-EN877:2006 version yangaphambili. Umahluko ophambili phakathi kweenguqulelo ezimbini malunga novavanyo ngolu hlobo lulandelayo:

1. Umda wovavanyo:

I-EN 877: 2006: Ikakhulu ivavanya iipropati zoomatshini kunye neempawu zokutywina zemibhobho kunye nokufakelwa.

I-EN 877: 2021: Ngokwesiseko sovavanyo lwangaphambili, iimfuno zovavanyo ezongeziweyo zentsebenzo yokugquma isandi, ukunganyangeki kwemichiza, ukumelana nomlilo kunye neminye imiba yenkqubo yemibhobho.

2. Iindlela zovavanyo:

I-EN 877: 2021 ihlaziya ezinye iindlela zovavanyo ukuze zizenze zenzululwazi kwaye zibe nengqiqo, ezinje:Uvavanyo lokuxhathisa kwimichiza: Izisombululo zovavanyo olutsha kunye neendlela zovavanyo ziyasetyenziswa, njengokusebenzisa isisombululo se-pH2 sulfuric acid endaweni yesisombululo sokuqala se-hydrochloric acid, kunye nokongeza iimvavanyo zokuxhathisa umhlwa kwiikhemikhali ezininzi.

Uvavanyo lwentsebenzo ye-Acoustic: Iimfuno zovavanyo ezongeziweyo zokwenziwa kwesandi sokugquma kwenkqubo yombhobho, njengokusebenzisa indlela yomgangatho woxinzelelo lwesandi ukulinganisa ukugquma kwesandi senkqubo yombhobho.

Uvavanyo lokusebenza komlilo: Iimfuno zovavanyo ezongeziweyo zokusebenza kokumelana nomlilo kwenkqubo yombhobho, njengokusebenzisa indlela yokumelana nomlilo ukuvavanya ukunyaniseka kwenkqubo yombhobho phantsi kweemeko zomlilo.EN 877:2021 isebenzisa ipeyinti enokumelana nomlilo ibakala A1

3. Iimfuno zovavanyo:

I-EN 877: 2021 yonyuse iimfuno zovavanyo kwezinye zezalathisi zokusebenza, ezinje:Amandla okuqina: anyuke ukusuka kwi-150 MPa ukuya kwi-200 MPa.
Ukwandiswa: kunyuswe ukusuka kwi-1% ukuya kwi-2%.

Ukuxhathisa kwi-Chemical corrosion resistance: Iimfuno ezongeziweyo zokuchasa umhlwa kwizinto ezininzi zeekhemikhali, ezifana neemfuno zokuxhathisa ukubola kwezinto zealkaline ezifana ne-sodium hydroxide kunye ne-potassium hydroxide.

4. Ingxelo yovavanyo:

I-EN 877: 2021 ineemfuno ezingqongqo kumxholo kunye nefomathi yengxelo yovavanyo, efana nale:Ifuna ingxelo yovavanyo ukuba ibandakanye ulwazi oluneenkcukacha ezifana neendlela zovavanyo, iimeko zovavanyo, iziphumo zovavanyo, kunye nezigqibo.

Ingxelo yovavanyo kufuneka ikhutshwe yi-arhente yovavanyo eqeqeshiweyo. Umzekelo,I-DINSEN iqinisekiswe yi-CASTCO.
Umgangatho we-EN877:2021 ubanzi kwaye ungqongqo ngakumbi kuvavanyo kunomgangatho we-EN877:2006, obonisa uphuhliso lwamva nje lwetekhnoloji kunye neemfuno zentengiso kushishino lwemibhobho yentsimbi. Ukuphunyezwa komgangatho omtsha kuya kunceda ekuphuculeni umgangatho weemveliso zemibhobho yentsimbi kunye nokukhuthaza ukhuseleko kunye nokuthembeka kwenkqubo yokwakhiwa kwe-drainage.
