Uhlu loCoceko lweMizi-mveliso

Iimfuneko zoBuchule

JikeleleUkucoca iiShishini, Ukucoca iMizi-mveliso ngokuGqibeleleyo kunye nokucoca iMizi-mveliso ngokuGqibeleleyo kakhulu

Ukucoca ngokubanzi kwemizi-mveliso kubandakanya ukucoca umphezulu wezithuthi, iinqanawa kunye neenqwelo-moya, nto leyo enokususa kuphela ukungcola okurhabaxa.

Ukucoca ngokuchanekileyo kwemizi-mveliso kubandakanya ukucoca ngexesha lokucubungula iimveliso ezahlukeneyo kunye nokucoca umphezulu wezinto ezahlukeneyo kunye nezixhobo, ezibonakaliswa kukukwazi kwayo ukususa amasuntswana amancinci othuli.

Ukucocwa kwemizi-mveliso ngokuchanekileyo kakhulu kubhekisa ekucocweni ngokuchanekileyo kakhulu kweendawo zoomatshini, izinto ze-elektroniki, iindawo ezibonakalayo kunye nezinye izinto kwiinkqubo zokwenza ngokuchanekileyo, ngenjongo yokususa amasuntswana okungcola amancinci kakhulu.

Iindlela Zokucoca

Ukucoca umzimba kunyeUkucoca iikhemikhali

Ukucoca ngokwasemzimbeni kusebenzisa imigaqo ye-mechanics, i-acoustics, i-optics, umbane kunye ne-thermodynamics. Ixhomekeke kumandla angaphandle afana nokungqubana koomatshini, amaza e-ultrasonic, uxinzelelo olubi, uxinzelelo oluphezulu, impembelelo, imisebe ye-ultraviolet kunye nomphunga, isusa ukungcola kwiindawo zento ngaphandle kokutshintsha ukwakheka kweekhemikhali zezinto ezingcolisayo, oko kuthetha ukuba isakhiwo sokuqala se-chemical molecular asitshintshi.

①Iindlela zokucoca ngoomatshini: ukucoca i-sweeper kunye ne-scraper, ukucoca i-tube drilling, ukucoca nge-shot blasting.

②Ukucocwa nge-hydraulic: ukucocwa nge-hydraulic ngoxinzelelo oluphantsi olunoxinzelelo oluqala kwi-196 ukuya kwi-686 kilopascals, malunga ne-2 ukuya kwi-7 yeekhilogram-force ngesentimitha yesikwere, elingana ne-0.2 ukuya kwi-0.7 MPa.

③Ukucoca nge-hydraulic ngoxinzelelo oluphezulu: uxinzelelo lokucoca ngoxinzelelo oluphezulu lufikelela kwi-4900 kilopascals, malunga ne-50 kg-force nge-square centimeter, elingana ne-5 MPa. Le ndlela ikwaziwa njengokucoca nge-water jet ngoxinzelelo oluphezulu kwaye isetyenziswa ngoomatshini bokucoca ngoxinzelelo oluphezulu.

Ukucoca ngamakhemikhali kususa ukungcola okungaphezulu kwezinto ngokusebenzisa iikhemikhali kusetyenziswa iikhemikhali okanye ezinye izinyibilikisi. Imizekelo ibandakanya ukususa umhlwa kunye ne-limescale ngee-asidi ezahlukeneyo ze-inorganic okanye ze-organic, kunye nokususa amabala omphezulu ngee-oxidants. Iikhemikhali zisabela kwiingcoliseko zomphezulu okanye iileya ezigubungelayo (ezifana neediphozithi zesikali) ukuze zisuswe, kubandakanya ukuhlamba nge-asidi kunye nokuhlamba nge-alkaline ukuze kususwe isikali. Ukuthintela ukubola kwe-substrate ngexesha lokucoca ngamakhemikhali okanye ukulawula izinga lokubola ngaphakathi kwemida evumelekileyo, isixa esifanelekileyo se-corrosion inhibitors kunye nezongezo ezineempawu ezisebenzayo, ezingenayo nezimanzisayo zihlala zongezwa kwizisombululo zokucoca ngamakhemikhali.

Iindlela zokucoca；indlela yokuntywilisela, indlela yokujikeleza, indlela yokucoca kwi-intanethi (ekwabizwa ngokuba yindlela yokucoca ngamakhemikhali engayekiyo).

Umgaqo we-elektroniki wokulwa nokukhula kunye nokunciphisa iikali: amasimi ombane asebenza rhoqo ahlengahlengisa iimolekyuli zamanzi ukuze kufezekiswe iziphumo zokulwa nokukhula kunye nokunciphisa iikali. Xa amanzi edlula kwintsimi yombane esebenza rhoqo, ulwakhiwo lwawo lweemolekyuli luyatshintsha. Iimacromolecules zetshanelo zokuqala ezihambelanayo ziyahlukana zibe ziimolekyuli zamanzi enye. Ii-ions ezilungileyo nezingalunganga zeetyuwa ezinyibilikiswe emanzini zijikelezwe ziimolekyuli zamanzi nganye nganye, nto leyo enciphisa isantya sokuhamba kwazo, inciphisa ukungqubana okusebenzayo kwaye ibuthathaka ukutsalana kwe-electrostatic. Ii-ions azisenakukwazi ukuhlangana kwiindonga ezishushu okanye kwiindawo zepayipi, ngaloo ndlela zithintela ukwakheka kwesikali. Okwangoku, umzuzu owandisiweyo we-dipole weemolekyuli zamanzi uqinisa amandla azo okubopha ngee-ions zetyuwa ezilungileyo nezingalunganga (iimolekyuli ze-limescale), ithambise i-limescale kwiindawo ezishushu kunye neendonga zepayipi ukuze kube lula ukwahlukana kunye nokunciphisa iikali.

Ukungalingani kunye nokuhla kwe-static anti-scaling kufezekisa iinjongo ezifanayo nokuhla kwe-elektroniki ngokuguqula imeko yeemolekyuli zamanzi, nangona kuxhomekeke kwiintsimi ze-electrostatic endaweni yeziphumo ze-elektroniki. Indlela yokusebenza ikwi-polarity (ipropathi ye-dipole) yeemolekyuli zamanzi. Xa ii-dipole zamanzi zidlula kwintsimi ye-electrostatic, zihambelana ngokuqhubekayo nangokucwangcisiweyo ngeetshaja ezilungileyo nezingalunganga. Ii-ion zetyuwa ezinyibilikisiweyo emanzini zigqunywe zii-dipole zamanzi kwaye zihlelwe ngokulandelelana ngaphakathi kwamaqela e-dipole, zithintela ukuhamba kwazo ngokukhululekileyo kwaye zithintele ekusondeleni okanye ekubekeni kwiindonga zepayipi/izixhobo ukuze zenze i-limescale. Ukongeza, ioksijini ekhutshwa emanzini yenza ifilimu ye-oxide encinci kakhulu kwiindonga zepayipi ukunciphisa ukugqwala kodonga.

Ukucoca iMedia

Ukucoca ngamanzi kunye nokucoca okomileyo

Ukucoca okwenziwa kwimidiya engamanzi kudla ngokuchazwa njengokucoca ngamanzi, kwaye uninzi lweendlela zokucoca zemveli ziwela kolu didi.

Ukucoca okwenziwa kwi-gaseous media kuhlelwa njengokucoca okomileyo, kuquka ukucoca nge-laser, ukucoca nge-ultraviolet, ukucoca nge-plasma kunye nokucoca ngokuqhumisa umkhenkce owomileyo.

Izithinteli zokuGqobhoka

I-corrosion inhibitor yinto eyongezwa ngobuninzi obuncinci kwi-corrosive media ecothisa kakhulu i-corrosion yesinyithi. Le ndlela yokukhusela isinyithi yaziwa njengokhuseleko lwe-corrosion inhibitor.

Ulwahlulo lwee-Corrosion Inhibitors

Ngokwendlela yokusebenza: ii-anodic inhibitors, ii-cathodic inhibitors, ii-mixed-type inhibitors

Ngokweempawu zefilimu ekhuselayo: izithinteli zokwenza ifilimu ezixidayo, izithinteli zohlobo lwe-adsorption, izithinteli zokwenza ifilimu emvula

Ezinye iikhrayitheriya zokuhlelwa:

①Izithinteli zokugqwala ze-organic kunye ne-inorganic

②Izithinteli zokugqwala zesigaba solwelo, isigaba segesi kunye nesigaba esiqinileyo

③Izithinteli zokugqwala zentsimbi, ubhedu kunye ne-aluminium

④Izithinteli zokugqwala ezi-asidi, i-alkaline kunye ne-neutral

Izinto zokucoca

Ukucoca kwangaphambili, ukucoca okungayekiyo kunye nokucoca ukugcinwa kokucima

Ukucoca kwangaphambili

Izixhobo ezintsha zeekhemikhali kufuneka zicocwe kwaye zitshintshwe iikhemikhali ngaphambi kokuba ziqaliswe ukusebenza. Indlela yokusebenza iye yabonisa ukuba ukucocwa kweekhemikhali kunye nokutshintshwa kwazo ngaphambi kokuba ziqale ukusebenza kuzisa iingenelo ezibalulekileyo kukhuseleko lwemveliso kunye nokusebenza kakuhle koqoqosho, nto leyo evelisa imbuyekezo enkulu kwezoqoqosho.

Iinjongo zokucoca kunye nokudlulisa ubushushu ngaphambi kokuqeshwa

Isikali seemililo senziwe kwizinto zesinyithi ezikrwada ezifana neepayipi zentsimbi, iipleyiti zentsimbi kunye nentsimbi engatyiwayo ngexesha lokuqengqeleka. Umhlwa, i-welding slag, izinto zokuthintela umhlwa ezinamafutha ezisetyenziswa kwintsimbi ukukhusela umhlwa, uthuli, isanti, isamente, izinto zokuthintela ubushushu kunye nokunye ukungcola ziqokelelana kwizixhobo ngexesha lokwenziwa, ukuthuthwa, ukugcinwa kunye nokufakelwa. Njengoko umthamo wezixhobo usanda, ixesha elivela ekuvelisweni kweepayipi zentsimbi kunye neepleyiti, ngokwenziwa kwezixhobo, uthutho kunye nokufakelwa ukuya ekuqalisweni kokugqibela liyanda. Iindawo ezininzi zokudibanisa iintsimbi kunye neendawo ezinkulu ezishushu zikhokelela ekunyukeni komthamo opheleleyo wezinto ezingcolisayo kubandakanya isikali seentsimbi, umhlwa, i-welding slag, izinto zokuthintela umhlwa kunye nesanti.

Emva kokucoca, ifilimu exineneyo yokudlulisa iikhemikhali iyenzeka kwiindawo zesinyithi ezicocekileyo. Le filimu ithintela ngokufanelekileyo ukuphinda kuvele ukungcola kwaye inika ukhuseleko oluthembekileyo kwizixhobo ngokuchasene nokugqwala kunye neminye imiphumo yekhemikhali.

Ukucoca Okungapheliyo

Ezinye izixhobo zeekhemikhali azikwazi kumisa ukusebenza kokugcinwa nokucoca ngexesha lokuveliswa, nto leyo ekhuthaze uphuhliso lwetekhnoloji yokucoca engayekiyo. Izisombululo zokucoca zasekhaya ezivuthiweyo ezingayekiyo zenza ukuba kucocwe kwaye kungasetyenziswa iikhemikhali ngelixa izixhobo zisebenza, zikhusela ukusebenza kwezixhobo okuzinzileyo kunye nokusebenza kakuhle kwenkonzo.

Ukucoca Ukugcinwa Kokuvala

Ukucoca ukugcinwa kokuvalwa kubhekisa kwimisebenzi yokucoca eyenziwa kuzo zonke izixhobo ngexesha lokuhlaziywa okucwangcisiweyo lonyaka kwamashishini eekhemikhali. Ngokwesiqhelo, iiyunithi enye ziyacocwa ngeekhemikhali ezijikelezayo okanye zicocwe ngejethi yamanzi enoxinzelelo oluphezulu ngexesha lokulungiswa kokuvalwa.
