Izindaba

Ukuze usebenzise umkhiqizo ngokugcwele, umuntu kufanele aqale awuqonde kahle, futhi imiqulu enamabala anemibala ayihlukile. Okulandelayo, ake sizethule kumaroli ahlanganiswe ngombala.
Okokuqala, sidinga ukwazi ukuthi liyini ibhodi eliboshwe ngombala?

Umucu wensimbi ohlanganiswe ngombala usebenzisa umucu wensimbi oshisayo odiphu njengoba i-substrate ingenawo ungqimba lwezinc ukuze ivikeleke, kodwa futhi inokwembozwa okuphilayo kungqimba lwezinc ukuze imboze futhi ivikeleke, ivimbela umucu wensimbi ukuthi ungagqwali. Impilo yayo yesevisi icishe ibe yinde ngokuphindwe izikhathi ezingu-1.5 kune-strip yensimbi ethathiwe. Okwesibili, kudingeka siqale siqonde izinjongo zemiqulu enemibala enemibala? Amaroli ahlanganiswe ngombala akasindi, ayathandeka ngobuhle, futhi anokumelana nokugqwala okuhle. Angase futhi acutshungulwe ngokuqondile futhi ngokuvamile atholakala ngezithunzi ezimpunga ezimhlophe, ulwandle oluluhlaza okwesibhakabhaka, nokubomvu kwezitini. Asetshenziswa kakhulu ezimbonini zokukhangisa, ezokwakha, ezisebenza ekhaya, ifenisha, nezokuthutha.
Isendlalelo esisetshenziselwa amaroli ahlanganiswe ngombala kufanele sikhethe ama-resin afanelekile ngokuya ngezindawo ezihlukene zokusetshenziswa, njenge-polyester silicon modified polyester, i-polyvinyl chloride plastic sol, i-polyvinylidene chloride, njll. Abasebenzisi bangakhetha ngokuya ngokusetshenziswa kwabo abahlosile. Okulandelayo, udinga ukwazi ukwakheka kokunamathela:
Uhlobo lwesakhiwo sokumboza i-V
2/1: Faka isicelo kabili endaweni engaphezulu, kanye endaweni engezansi, bese ubhaka kabili.
2/1M: Gcoba kabili endaweni engaphezulu nengaphansi, bese ubhaka kanye.
2/2: Faka isicelo kabili endaweni engaphezulu nephansi, bese ubhaka kabili.
Ukusetshenziswa kwezakhiwo ezihlukene zokugqoka:
I-2/1: Ukumelana nokugqwala nokumelana nokuklwebheka kopende ongemuva onongqimba olulodwa akulungile, kodwa unokunamathela okuhle futhi usetshenziswa kakhulu kumaphaneli amasemishi;
I-2/1M: Upende ongemuva unokumelana nokugqwala okuhle, ukumelana nokuklwebheka, kanye nokwakheka kokucubungula, okunamathelayo okuhle, okulungele amaphaneli anephrofayili yongqimba olulodwa namaphaneli esangweji.
2/2: Upende ongemuva onezendlalelo ezimbili unokumelana nokugqwala okuhle, ukumelana nokuklwejwa, nokwakheka kokucutshungulwa, futhi usetshenziswa kakhulu kumaphaneli anephrofayili yongqimba olulodwa. Kodwa-ke, ukunamathela kwayo kubi futhi akufanelekile kumaphaneli amasemishi.

Yiziphi izigaba zama-substrates ahlanganiswe ngombala?
I-dip eshisayo engaphansi kwe-galvanized substrate
Umkhiqizo otholwe ngokufaka i-organic enamathela eshidini lensimbi elicwengekileyo elishisayo uyishidi elinombala oshisayo odiphu. Ishidi elinombala oshisayo wediphu elinombala oshisayo aligcini nje ngokuba nomphumela wokuvikela we-zinc, kodwa ukunamathela kwemvelo okungaphezulu nakho kudlala indima ekuvikeleni ukuvikela nokugqwala, okunempilo ende yesevisi kuneshidi le-hot-dip galvanized. Okuqukethwe kwe-zinc kuma-hot-dip galvanized substrates ngokuvamile kungu-180g/m2 (izinhlangothi ezikabili), futhi okuqukethwe kwe-zinc okuphezulu kwama-galvanized substrates adiphu ashisayo ukuze asetshenziswe ngaphandle ezakhiweni ngu-275g/m2.
I-substrate ye-aluminium ye-dip eshisayo
Ipuleti lensimbi ye-dip aluminium zinc (55% Al Zn) lisetshenziswa njengengxenye esanda kugqitshwa, ngokuvamile enokuqukethwe kwe-aluminium zinc engu-150g/㎡ (izinhlangothi ezimbili). Ukumelana neshidi le-aluminiyamu ye-hot-dip zinc izikhathi ezingu-2-5 kuneshidi elishisayo le-dip galvanized. Ukusetshenziswa okuqhubekayo noma kwezikhawu emazingeni okushisa afika ku-490 ℃ ngeke kubangele i-oxidation eqinile noma ukwakheka kwezikali ze-oxide. Amandla okubonisa ukushisa nokukhanya aphindwe kabili kunepuleti lensimbi elidiphu elishisayo, futhi ukubonakala okukhulu kuno-0.75 kuyindlela yokwakha efanelekile yokonga amandla.
I-electroplated galvanized substrate
Umkhiqizo otholwe ngokusebenzisa i-electroplated galvanized sheet njenge-substrate futhi uyibhake nge-organic coating i-electroplated galvanized color coated sheet. Ngenxa yongqimba oluncane lwezinc lweshidi eliphehliwe kagesi kagesi, okuqukethwe kwe-zinc kuvame ukuba ngu-20/20g/m2, ngakho-ke lo mkhiqizo awufanele ukusetshenziswa ngaphandle ekwenzeni izindonga, uphahla, njll. Kodwa ngenxa yokubukeka kwawo okuhle nokusebenza kokucubungula, ingasetshenziselwa kakhulu izinto zasendlini, amasistimu alalelwayo, ifenisha yensimbi, imihlobiso yasendlini, njll. Lapho uzwa lokhu, ingabe unalo ulwazi mayelana namaroli ahlanganiswe ngombala? Uma unentshisekelo, woza uzosithinta!
