Iphansi elizipholishayo lesembozo sokuvikela ukungcola kolwandle
Incazelo Yomkhiqizo
Upende wokuzigcoba ozimele uwumkhiqizo okhethekile wokumboza. Ngokuyinhloko ubhekana nokusabela kwamakhemikhali ebusweni bokumboza. Njengoba umkhumbi uhamba emanzini, ukumboza kuzopholisha kancane kancane futhi ngokulinganayo futhi kuncibilike ngokwako. Lesi sici senza ubuso bomkhumbi buhlale buhlanzekile futhi buvimbele ngempumelelo izinto eziphilayo zasolwandle ezifana ne-shellfish kanye ne-algae ukuthi zinganamatheli esikhumbeni.
Umgomo wokulwa nokungcola kopende wokuzipholisha usekelwe ekwakhiweni kwawo kwamakhemikhali okuhlukile. Uqukethe ama-polymer angafakwa emanzini kanye nezithasiselo ezinobuthi bezinto eziphilayo. Endaweni yasemanzini olwandle, ama-polymer azofakwa emanzini kancane kancane, avuselele njalo ubuso bopende wokulwa nokungcola, kuyilapho izithasiselo ezinobuthi bezinto eziphilayo zingavimbela ukunamathela kwezinto eziphilayo zasolwandle endaweni entsha eveziwe.
- Uma kuqhathaniswa nopende wendabuko wokulwa nokungcola, upende wokulwa nokungcola ozipholishayo unezinzuzo ezibalulekile. Ngemva kokusetshenziswa kopende wendabuko wokulwa nokungcola isikhathi esithile, umphumela wokulwa nokungcola uzoncipha kancane kancane, futhi kudingeka ukuphinda kusetshenziswe njalo. Lokhu akugcini nje ngokudla isikhathi esiningi nezindleko kodwa futhi kungaba nomthelela othile emvelweni. Ngokuphambene nalokho, upende wokulwa nokungcola ozipholishayo ungaqhubeka nokusebenzisa umphumela wawo wokulwa nokungcola isikhathi eside, kunciphisa imvamisa yokugcinwa kwemikhumbi eyomile kanye nokuphinda kusetshenziswe.
- Ezisetshenzisweni ezisebenzayo, upende wokuzigcoba ovikela ukungcola usetshenziswa kabanzi ezinhlotsheni ezahlukene zemikhumbi, okuhlanganisa imikhumbi yokuhweba, imikhumbi yempi, kanye nemikhumbi yempi. Emikhumbi yokuhweba, ukugcina isikebhe sihlanzekile kunganciphisa ukumelana kokuhamba ngomkhumbi futhi kuthuthukise ukusebenza kahle kukaphethiloli, ngaleyo ndlela konge izindleko zokusebenza. Emikhumbi yempi, ukusebenza kahle kokuvimbela ukungcola kusiza ukuqinisekisa isivinini sokuhamba ngomkhumbi kanye nokuhamba kwawo futhi kuthuthukisa ukusebenza kahle kokulwa. Emikhumbi yempi, ingagcina isikebhe sibukeka sisesimweni esihle ngaso sonke isikhathi futhi ithuthukise ubuhle.
- Njengoba izidingo zokuvikela imvelo ziqhubeka ziqina, upende wokuzigcoba ozivikelayo nawo uhlala uthuthuka futhi usungula izinto ezintsha. Abasebenzi be-R & D bazibophezele ekunciphiseni ukusetshenziswa kwezithasiselo ezinobuthi bezinto eziphilayo kuwo ngenkathi bethuthukisa ukusebenza kopende wokuzigcoba ukuze kufezwe umphumela wokuzigcoba onobungani nemvelo futhi ophumelelayo. Amanye amapende amasha okuzigcoba azivikelayo asebenzisa ubuchwepheshe be-nanotechnology ukuthuthukisa ikhono lawo lokuzigcoba kanye nokusebenza kokuzigcoba ngokushintsha isakhiwo esincane sengubo. Esikhathini esizayo, upende wokuzigcoba ozivikelayo kulindeleke ukuthi udlale indima enkulu emkhakheni wobunjiniyela bolwandle futhi unikeze ukwesekwa okuqinile ekuthuthukisweni kwemboni yasolwandle.
Izici eziyinhloko
Vimbela izinto eziphilayo zasolwandle ekubangeleni umonakalo phansi komkhumbi, ugcine phansi kuhlanzekile; Yenza ukupholisha ngokuzenzakalelayo nangokushesha ukuze unciphise ukujiya phansi komkhumbi, ngomphumela omuhle wokunciphisa ukuhudula; Ayiqukethe izibulala-zinambuzane ezisekelwe ku-organotin, futhi ayinangozi endaweni yasolwandle.
isigcawu sohlelo lokusebenza
Isetshenziselwa izingxenye ezingaphansi kwamanzi zesakhiwo somkhumbi kanye nezakhiwo zasolwandle, ivimbela izinto eziphilayo zasolwandle ukuthi zinganamatheli. Ingasetshenziswa njengopende wokulungisa ovimbela ukungcola kwesisekelo semikhumbi ehileleke ekuzulazuleni komhlaba wonke kanye nokufika endaweni yesikhashana.
ukusetshenziswa
Izidingo Zobuchwepheshe
- Ukwelashwa kwendawo: Zonke izindawo kumele zihlanzeke, zome futhi zingangcoliswa. Kufanele zihlolwe futhi ziphathwe ngokuhambisana ne-ISO8504.
- Izindawo ezimbozwe ngopende: I-primer coating ehlanzekile, eyomile futhi engashintshi. Sicela uxhumane nomnyango wezobuchwepheshe wesikhungo sethu.
- Ukulungiswa: Izindawo ezigqwalile, eziphathwe ngejethi yamanzi enomfutho ophezulu kakhulu ezingeni le-WJ2 (NACENo.5/SSPC Sp12) noma ngokuhlanza amathuluzi kagesi, okungenani izinga le-St2.
- Ezinye izindawo: Lo mkhiqizo usetshenziselwa ezinye izinto ezisetshenziswayo. Sicela uxhumane nomnyango wezobuchwepheshe wesikhungo sethu.
- Upende ohambisanayo ngemva kokusetshenziswa: Ama-primer asekelwe emanzini, ancibilika ku-alcohol-soluble zinc series, ama-primer acebile nge-epoxy zinc, ama-primer alwa nokugqwala asezingeni eliphansi, upende okhethekile wokususa ukugqwala kanye nopende wokulwa nokugqwala, ama-primer e-phosphate zinc, upende we-epoxy iron oxide zinc anti-rust, njll.
- Ukupenda okufana ngemva kokusetshenziswa: Akukho.
- Izimo zokwakha: Izinga lokushisa le-substrate akufanele libe ngaphansi kuka-0℃, futhi okungenani libe ngu-3℃ ngaphezulu kwezinga lokushisa le-air dew point (izinga lokushisa kanye nomswakama ohlobene kufanele kulinganiswe eduze kwe-substrate). Ngokuvamile, kudingeka umoya omuhle ukuqinisekisa ukuthi upende woma ngendlela evamile.
- Izindlela zokwakha: Ukupenda ngokufutha: Ukufutha ngaphandle komoya noma ukufutha ngosizo lomoya. Kunconywa ukusebenzisa ukufutha ngaphandle komoya ngomfutho ophezulu. Uma usebenzisa ukufutha ngosizo lomoya, kufanele kunakwe ukulungisa ukujiya kopende kanye nomfutho womoya. Inani lokuncipha akufanele lidlule u-10%, ngaphandle kwalokho kuzothinta ukusebenza kokumboza.
- Ukupenda ngebhulashi: Kunconywa ukuthi kusetshenziswe ekupendeni kwangaphambilini kanye nasekupendeni endaweni encane, kodwa kumele kufinyelele ubukhulu befilimu eyomile obubekiwe.
Amanothi Okunakekelwa
Lesi simbozo siqukethe izinhlayiya ze-pigment, ngakho-ke kufanele sixutshwe kahle futhi sivuselelwe ngaphambi kokusetshenziswa. Ubukhulu befilimu yopende yokulwa nokungcola bunomthelela omkhulu emphumeleni wokulwa nokungcola. Ngakho-ke, inani lezingqimba zokugqoka alikwazi ukuncishiswa futhi i-solvent akufanele ifakwe ngokungahleliwe ukuqinisekisa ukuqina kwefilimu yopende. Impilo Nokuphepha: Sicela unake izimpawu zesixwayiso esitsheni sokupakisha. Sebenzisa endaweni enomoya omuhle. Ungahogeli inkungu yopende futhi ugweme ukuthintana nesikhumba. Uma upende usakazeka esikhumbeni, hlanza ngokushesha nge-ejenti yokuhlanza efanele, insipho namanzi. Uma usakazeka emehlweni, hlanza ngamanzi amaningi bese ucela ukwelashwa ngokushesha.
