Ukuhlolwa kwe-acid-base ye-DINSEN Cast Iron Pipe

Ukuhlolwa kwe-acid-base ye-DINSENipayipi lensimbi(ebuye ibizwe ngepayipi le-SML) ivamise ukusetshenziselwa ukuhlola ukumelana nokugqwala kwayo, ikakhulukazi ezindaweni ezine-acidic kanye ne-alkaline. Amapayipi okudonsa amanzi e-cast iron asetshenziswa kakhulu ekunikezeni amanzi, amapayipi amanzi kanye nezinhlelo zamapayipi ezimbonini ngenxa yezakhiwo zawo ezinhle kakhulu zemishini kanye nokumelana nokugqwala. Okulandelayo yizinyathelo ezijwayelekile kanye nezinyathelo zokuphepha zokwenza ukuhlolwa kwe-acid-base kumapayipi e-SML:

Inhloso yokuhlolwa
Linganisa ukumelana nokugqwala kwamapayipi e-iron ductile ezindaweni ezine-asidi ne-alkaline.
Thola ukuzinza kwayo kwamakhemikhali ngaphansi kwezimo ze-pH ezihlukene.
Nikeza ireferensi yokukhetha izinto ezisetshenziswayo.

Izinto zokuhlola
Amasampula epayipi lensimbi (sika amasayizi afanele).
Izixazululo ezine-Acidic (njenge-dilute sulfuric acid, i-dilute hydrochloric acid, inani le-pH lingalungiswa njengoba kudingeka).
Izixazululo ze-alkaline (njengesisombululo se-sodium hydroxide, inani le-pH lingashintshwa njengoba kudingeka).
Iziqukathi (ingilazi engazweli acid noma iziqukathi zepulasitiki).
Amathuluzi okulinganisa (imitha ye-pH, ibhalansi kagesi, i-vernier caliper, njll.).
Imishini yokulinganisa izinga lokugqwala (okufana nehhavini yokomisa kanye nebhalansi edingekayo endleleni yokulahlekelwa isisindo).
Imishini yokuzivikela (amagilavu, izibuko, amajazi elebhu, njll.).

Izinyathelo zokuhlola
Ukulungiselela isampula:
Sika isampula yepayipi le-SML futhi uqinisekise ukuthi indawo engaphezulu ihlanzekile futhi ayinawo uwoyela.
Linganisa futhi urekhode usayizi wokuqala nesisindo sesampula.

Lungiselela ikhambi:
Lungiselela isixazululo esine-asidi nesisombululo se-alkaline yenani le-pH elidingekayo.
Sebenzisa imitha ye-pH ukulinganisa i-pH yesisombululo.

Ukuhlolwa kokucwiliswa:
Gxilisa isampula yepayipi lensimbi elicijile le-DINSEN esixazululweni esine-asidi nesisombululo se-alkaline ngokulandelana.
Qiniseka ukuthi isampula icwiliswe ngokuphelele futhi urekhode isikhathi sokucwiliswa (njengamahora angama-24, izinsuku eziyi-7, izinsuku ezingama-30, njll.).

Ukubuka nokurekhoda:
Bheka izinguquko ezingaphezulu kwesampula njalo (njengokugqwala, ukushintsha kombala, imvula, njll.).
Rekhoda ukushintsha kombala kwesixazululo kanye nokwakheka kwezulu.

Susa isampula:
Ngemuva kokuthi isikhathi esinqunyiwe sesifinyelelwe, susa isampula bese uyihlanza ngamanzi a-distilled.
Yomisa isampula bese ukala isisindo salo kanye nokushintsha kosayizi.

Ukubalwa kwezinga lokugqwala:
Izinga lokugqwala libalwa kusetshenziswa indlela yokulahlekelwa isisindo, futhi ifomula ithi:Izinga lokugqwala = indawo engaphezulu × isikhathi

Ukuncipha kwesisindo:
Qhathanisa amazinga okugqwala ezindaweni ezine-acidic ne-alkali.

Ukuhlaziywa kwemiphumela:
Hlaziya ukumelana nokugqwala kwamapayipi e-iron ductile ngaphansi kwezimo ze-pH ezihlukene.
Linganisa ukusebenza kwayo ezinhlelweni ezingokoqobo.

Izinyathelo zokuzivikela
Ukuvikela ukuphepha:
Izixazululo ze-Acid ne-alkali ziyagqwala, futhi abahlolayo badinga ukugqoka izinto zokuzivikela.
Ukuhlolwa kufanele kwenziwe endaweni enomoya omuhle.

Ukugxilisa isixazululo:
Khetha i-asidi efanele kanye nokugxiliswa kwe-alkali ngokuya ngesimo sangempela sohlelo lokusebenza.

Ukucubungula isampula:
Qinisekisa ukuthi indawo yesampula ihlanzekile ukuze ugweme ukungcola okuthinta imiphumela yokuhlolwa.

Isikhathi sokuhlola:
Setha isikhathi sokucwiliswa esiphusile ngokuya nenjongo yokuhlolwa ukuze uhlole ngokugcwele ukusebenza kokugqwala.

Imiphumela yokuhlola nezinhlelo zokusebenza

Uma ipayipi le-iron ductile libonisa izinga eliphansi lokugqwala endaweni ye-acid-base, kusho ukuthi inokumelana nokugqwala okuhle futhi ifanele indawo yamakhemikhali eyinkimbinkimbi.

Uma izinga lokugqwala liphezulu, kungase kudingeke izinyathelo ezengeziwe zokunqanda ukugqwala (njengokumboza noma ukuvikela i-cathodic).

Ngokuhlolwa kwe-acid-base, ukuzinza kwamakhemikhali kwamapayipi ensimbi e-ductile kungaqondwa ngokugcwele, kunikeze isisekelo sesayensi sokusetshenziswa kwawo ezindaweni ezithile.
