Intshayelelo emfutshane yovavanyo loxinzelelo lweasidi

Umvavanyi woxinzelelo lwe-asidi ye-acid usetyenziswa ikakhulu ukuvavanya ukuxhathisa kuxinzelelo lwe-static (uxinzelelo lwe-asidi ye-static) ye-asidi yelaphu kunye nesiseko sempahla ekhuselayo yemichiza.Sisixhobo sokuvavanya i-asidi kunye nesiseko sempahla yeekhemikhali zokukhusela i-asidi kunye nesiseko samashishini okuvelisa imichiza kwilayisenisi yokuvelisa kunye ne-LA (Lao-an) isatifikethi, iiyunithi zokulawula kunye nokuvavanya kunye namaziko ophando lwesayensi.Hlangana nomgangatho: GB24540-2009;

Iimpawu zovavanyo loxinzelelo lwe-asidi engatshintshiyo:

I-1, ukusetyenziswa kwebhokisi yokulawula umbane kunye nemodi yokwahlula ibhokisi yovavanyo, ugweme uhlobo lwebhokisi lovavanyo lwe-asidi yokuvuza imingcipheko yokhuseleko lwesekethe.

I-2, igumbi lokuvavanya lenziwe ngezinto zensimbi ezingenasici, ezinciphisa amathuba okuba ne-asidi yebhokisi, ukuze ibhokisi ikwazi ukugcina isibuko sigudile ixesha elide.

I-3, umbhobho wokuvavanya izixhobo, umlomo wenaliti yolwelo kunye nekliphu yesampulu esebenzisa ukugqwala kwe-polytetrafluoroethylene enganyangekiyo, xa kuthelekiswa nemathiriyeli yentsimbi, iphucula kakhulu ukuxhathisa ukubola kunye nobomi benkonzo.

4, umbhobho wokuvavanya usebenzisa umbhobho otyaliweyo weptfe, ukuqinisekisa ukuba akukho amaqamza xa udibanisa ulwelo, ukuqukuqela kolwelo okugudileyo ngakumbi, ukuphucula ukuchaneka kunye nexesha elifanelekileyo lovavanyo.

I-5, i-DRK711 i-static acid tester pressure tester ithatha isakhiwo soyilo esisodwa, siphucule ukuchaneka kwezixhobo, ukusuka ekuchanekeni kokuqala kwe-3mm ukuya kwi-1mm.

I-6, umphambili wezixhobo zokwandisa isikali, nokuba abasebenzi bokulinga nangaliphi na ixesha ukuqinisekisa ukuchaneka kweziphumo zovavanyo, kunye nokulinganisa izixhobo ezifanelekileyo.

I-7, umlomo wenaliti yolwelo kunye nesampuli yekliphu yekliphu ebonakalayo ebonakalayo, ukuphucula ukhuseleko lwe-asidi kunye novavanyo lwealkali.

8. Umnini wesampuli wamkela isakhiwo esikhethekileyo ukuqinisekisa ukuba isampuli ikwimeko eqinile;I-specimen clamping plate ithatha isakhiwo esijikelezayo esisecaleni, esikhuselekileyo nesilungele ukusebenza, kwaye siphucula ukusebenza kovavanyo kunye nokuchaneka kweziphumo zovavanyo.
