I-Zn Hotplating

Amabhuloho Nezakhiwo Zensimbi:

Isetshenziselwa ukuxhuma izingxenye ezifana nemishayo eyinhloko yebhuloho, ama-trusses, ama- guardrails, njll., ukumelana nokugqwala kwamanzi emvula nama-ejenti ancibilikisa iqhwa (ama-chloride salts).

Ngokwesibonelo, amabhawodi ebhuloho eliwela ulwandle adinga ukumelana nomswakama ophezulu kanye nokuguguleka kwesifutho sikasawoti, futhi ungqimba olunamanzi olwandle olushisayo lunganikeza isivikelo iminyaka engaphezu kwengu-20.

Imigwaqo emikhulu nezitimela:

Ama-guardrails agxilile, amaphaneli okufaka umsindo, kanye nezixhumi zokulandelela ukubhekana nemvula ene-asidi, i-motor exhaust (i-sulphur dioxide), kanye nokungcoliswa kwezimboni.

Imibhoshongo yokudlulisa kanye nemibhoshongo yokuxhumana:

Isetshenziselwa ukuxhuma izisekelo zemibhoshongo yensimbi kanye nezikhali eziphambanayo, ingakwazi ukumelana nemisebe ye-ultraviolet, ukuduma kwezulu, kanye nezindawo zenkungu ene-asidi ezindaweni eziphakeme kakhulu.

2. I-Marine and Port Engineering
Izinsiza zedokhu:

Iziphepheli ezigxilile, amakholomu okubopha, izinqwaba zensimbi, nokucwiliswa isikhathi eside emanzini olwandle ukuze kumelane nokugqwala kwe-chloride ion.

Ukunakekelwa okuvamile (okufana nokupenda kabusha ngopende ovimbela ukugqwala) kuyadingeka ukuze kunwetshwe isikhathi sokuphila.

Imikhumbi nezinkundla zasolwandle:

Ukuqiniswa kwemishini yedekhi kanye nezisekelo zamapayipi kufanele kuphumelele ukuhlolwa kwesifutho sikasawoti se-ISO 9227 (akukho ukugqwala okubomvu amahora angaphezu kuka-1000).

Qaphela: Izindawo ezijulile zolwandle zingase zidinge ukuthuthukela ekuvikelekeni okumbaxambili kwe-hot-dip galvanizing kanye ne-epoxy coating.

3. Izimboni kanye nezamandla
Imishini yamakhemikhali:

Ubakaki wethangi lokusabela okungaguquki, i-flange yepayipi, imelana namagesi ane-asidi ne-alkaline (njenge-hydrogen sulfide), izinga lokushisa eliphezulu nendawo enomswakama ophezulu.

Izimo ezisebenzayo: Imishini yangaphandle ezitshalweni zamakhemikhali nasezimbonini zokuhluza.

Amandla omoya nama-photovoltaics:

Amabhawodi e-wind turbine tower adinga ukumelana nokudlidliza komthwalo womoya, isifutho sikasawoti osogwini, nomehluko wokushisa (-30 ° C kuya ku-50 ° C).

Amabhawudi abakaki be-photovoltaic adinga ukumelana nokuguga kwe-UV futhi agweme ukugcotshwa kwempushana (i-hot-dip galvanizing ingcono kune-electroplating galvanizing).

Izinsiza zezolimo:

I-Greenhouse steel frame nezixhumi zemishini yokunisela ukuze kuvinjelwe ukugqwala okubangelwa izindawo ezinomswakama wesikhathi eside.

4. Izinsiza zikamasipala nezomphakathi
Izibani zomgwaqo namalambu esignali:

Isisekelo sesibani kanye ne-cantilever kugxilile ukumelana nokuguguleka kwemvula ye-asidi yasemadolobheni kanye nezinto ezincibilikisa iqhwa.

Indawo yokuhlanza indle:

Isakhiwo sensimbi esixhuma ithange lokungenisa umoya kanye nethangi le-sedimentation alikwazi ukumelana negesi ye-hydrogen sulfide kanye nokuchaphazeka kwendle.

5. Izimo Ezikhethekile Nezinyathelo Zokuqapha
Izindawo ezinosawoti omningi we-alkali:

Isibonelo, enyakatho-ntshonalanga yezwe eline-alkali enosawoti kanye nasezindaweni ezisogwini olusogwadule lwaseMpumalanga Ephakathi, amabhawodi afaka uthango ashisayo adinga ukugcotshwa ngongqimba olujiyile (≥ 80 μ m).

Indawo yokudlidliza:

Amabhawodi amathrekhi kaloliwe nemishini yezimayini adinga ukufaniswa namantongomane avimbela ukuxega (njengamantongomane akhiya inayiloni) ukuze kugwenywe ukuxega ngenxa yokudlidliza.

Indawo yokushisa ephezulu:

Izimo zesikhathi eside ezingaphezu kuka-200 ° C, njengamabhoyili azungezile, zingase zisheshise ukufakwa kwe-oxidation kwezingqimba ze-zinc futhi zidinge ukusetshenziswa kwensimbi engagqwali noma amabhawodi afakwe ezinki.

Iziphakamiso zokukhetha
Indawo enokhahlo: Beka kuqala amabhawodi anabakantshisi adiphu ashisayo futhi usebenzise izinto zokuvala (ezifana nokwelashwa kwe-phosphating) noma izimbotshana eziyinhlanganisela.

Izimo ezizwelayo ezindlekweni: Amaphrojekthi esikhathi esifushane noma indawo enokugqwala okuphansi (njengezindawo ezomile zasendlini) zingakhetha ukwenza uthayela, kodwa ukuhlolwa okuvamile kuyadingeka.

Isidingo samandla aphezulu: Amabhawodi ebanga le-10.9 nangaphezulu kufanele enziwe ukwelashwa kwe-dehydrogenation ukuze kugwenywe ingozi yokugqama kwe-hydrogen nokuphuka.

finyeza
Amabhawodi afakwe uthayela we-dip eshisayo ayinketho "yezinga lokuzivikela" ezindaweni ezigqwala kakhulu, afaneleka ikakhulukazi ngaphandle, olwandle, amakhemikhali nezinye izimo. Inani layo eliyinhloko lisekushintshisaneni ngezindleko eziphakeme zokuqala ngezindleko eziphansi kakhulu zokulungiswa kwangemuva, okuyenza ifanelekele amaphrojekthi anezidingo eziphezulu zokuphepha nokuqina.
