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 yokuhlukanisa 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 we-ptfe ocacileyo, ukuqinisekisa ukuba akukho amaqamza xa udibanisa ulwelo, ukuhamba 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 nekliphu yesampulu ecacileyo 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.
