Uvavanyo lwe-acid-base ye-DINSEN Cast Iron Pipe

Uvavanyo lwe-acid-base ye-DINSENumbhobho wentsimbi(ekwabizwa ngokuba ngumbhobho we-SML) isoloko isetyenziselwa ukuvavanya ukuxhathisa kwayo kokubola, ngakumbi kwiindawo ezineasidi kunye ne-alkaline. Imibhobho yokuhambisa intsimbi yentsimbi isetyenziswa ngokubanzi kunikezelo lwamanzi, ukuhanjiswa kwamanzi kunye neenkqubo zemibhobho yemizi-mveliso ngenxa yeempawu zayo ezigqwesileyo zoomatshini kunye nokumelana nokugqwala. Oku kulandelayo ngamanyathelo ngokubanzi kunye nezilumkiso zokuqhuba uvavanyo lwe-acid-base kwimibhobho ye-SML:

Injongo yovavanyo
Vavanya ukuxhathisa kokubola kwemibhobho yentsimbi ye-ductile kwiindawo ezineasidi kunye ne-alkaline.
Qinisekisa ukuzinza kwayo kweekhemikhali phantsi kweemeko ezahlukeneyo ze-pH.
Ukubonelela ngereferensi yokukhethwa kwezinto eziphathekayo kwizicelo ezibonakalayo.

Imathiriyeli yovavanyo
Iisampulu zemibhobho yentsimbi (zisikwe kwiisayizi ezifanelekileyo).
Izisombululo ze-Acidic (ezifana ne-dilute sulfuric acid, i-dilute hydrochloric acid, ixabiso le-pH linokulungiswa njengoko kufuneka).
Izisombululo ze-alkaline (ezifana nesisombululo se-sodium hydroxide, ixabiso le-pH linokulungiswa njengoko kufuneka).
Izikhongozeli (iglasi enganyangekiyo kwi-asidi okanye izikhongozeli zeplastiki).
Izixhobo zokulinganisa (imitha ye-pH, ibhalansi ye-elektroniki, i-vernier caliper, njl.).
Izixhobo zokulinganisa izinga lokubola (ezifana ne-oven yokomisa kunye nebhalansi efunekayo kwindlela yokulahlekelwa kwesisindo).
Izixhobo zokukhusela (iiglavu, iiglasi, iidyasi zaselebhu, njl. njl.).

Amanyathelo ovavanyo
Ukulungiselela isampuli:
Sika isampuli yombhobho we-SML kwaye uqinisekise ukuba umphezulu ucocekile kwaye awunayo ioli.
Ukulinganisa kunye nokurekhoda ubungakanani bokuqala kunye nobunzima besampuli.

Lungiselela isisombululo:
Lungisa isisombululo se-acidic kunye ne-alkaline yexabiso elifunekayo le-pH.
Sebenzisa imitha ye-pH ukulinganisa i-pH yesisombululo.

Umfuniselo wokuntywiliselwa:
Gxininisa isampuli ye-DINSEN yentsimbi yombhobho kwisisombululo se-acidic kunye nesisombululo sealkali ngokulandelelanayo.
Qinisekisa ukuba isampulu intywiliselwe ngokupheleleyo kwaye urekhode ixesha lokuntywiliselwa (njengeeyure ezingama-24, iintsuku ezisi-7, iintsuku ezingama-30, njl. njl.).

Ukuqwalaselwa kunye nokurekhoda:
Qwalasela iinguqu kumphezulu wesampulu rhoqo (ezifana ne-corrosion, discoloration, precipitation, njl.).
Rekhoda utshintsho lombala wesisombululo kunye nokwakheka kwemvula.

Susa isampuli:
Emva kokuba ixesha elimisiweyo lifikelelwe, susa isampuli kwaye uyihlambulule ngamanzi adibeneyo.
Yomisa isampuli kwaye ulinganise ubunzima bayo kunye noshintsho lobungakanani.

Ubalo lwezinga lokurhweba:
Umlinganiselo wokubola ubalwa kusetyenziswa indlela yokulahlekelwa ubunzima, kwaye ifomula yile:Izinga lokutya = indawo ephezulu × ixesha

Ukuhla ukusinda:
Thelekisa amazinga okuhlwa kwiindawo ezineasidi kunye ne-alkaline.

Uhlalutyo lweziphumo:
Hlalutya ukuxhatshazwa kwe-corrosion ye-ductile iron pipes phantsi kweemeko ezahlukeneyo ze-pH.
Vavanya ukufaneleka kwayo kwizicelo ezibonakalayo.

Ukulumkela
Ukhuseleko lokhuseleko:
Izisombululo zeAcid kunye nealkali ziyonakalisa, kwaye abenzi bovavanyo kufuneka banxibe izixhobo zokukhusela.
Uvavanyo kufuneka lwenziwe kwindawo enomoya owaneleyo.

Ugxininiso lwesisombululo:
Khetha i-asidi efanelekileyo kunye nogxininiso lwe-alkali ngokwemeko yokusetyenziswa kwangempela.

Isampulu yokuqhubela phambili:
Qinisekisa ukuba umphezulu wesampulu ucocekile ukunqanda ukungcola okuchaphazela iziphumo zovavanyo.

Ixesha lovavanyo:
Misela ixesha lokuntywiliselwa elifanelekileyo ngokwenjongo yovavanyo lokuvavanya ngokupheleleyo ukusebenza komhlwa.

Iziphumo zovavanyo kunye nezicelo

Ukuba umbhobho we-iron ductile ubonisa izinga eliphantsi le-corrosion kwindawo ye-acid-base-base, kuthetha ukuba inokumelana nokugqwala okulungileyo kwaye ifanelekile kwiindawo eziyinkimbinkimbi zeekhemikhali.

Ukuba izinga lokubola liphezulu, imilinganiselo eyongezelelweyo yokunqanda ukubola (efana nokugquma okanye ukukhuselwa kwe-cathodic) kunokufuneka.

Ngokusebenzisa iimvavanyo ze-acid-base, ukuzinza kweekhemikhali zemibhobho yensimbi ye-ductile kunokuqondwa ngokupheleleyo, ukubonelela ngesiseko sesayensi sokusetyenziswa kwazo kwiindawo ezithile.
