Ungasiza Kanjani Amaphrojekthi e-Ericsson Signal Tower Ukuxazulula Ukubopha Endaweni Ebandayo Ekhanyisiwe?

Emkhakheni wokwakha nengqalasizinda, ikakhulukazi embonini yezokuxhumana, kubaluleke kakhulu ukukhetha uhlelo lokumboza olufanele lwezingqalasizinda. Kumaphrojekthi afana nokufakwa kwemibhoshongo ye-Ericsson, inselele enkulu ukukhetha uhlelo lokumboza olufanele lwensimbi ebanda ene-galvanized. Ukufaka i-galvanization ebandayo kuyinqubo emboza ubuso bensimbi nge-zinc ecebile ukuvimbela ukugqwala. Kodwa-ke, le substrate ethile inikeza izinselelo ezihlukile maqondana nokunamathela kokufaka kanye nokuqina. I-Forest Paint njengomhlinzeki wokumboza wesistimu yokumboza imibhoshongo yesignali ye-Ericsson, sizohlola ukuthi singakhetha kanjani uhlelo lokumboza olufanele lokuvimbela ukugqwala ukuqinisekisa ukuqina nokusebenza kwemibhoshongo yesignali ye-Ericsson.

Ukuqonda Izindawo Ezibandayo Ezihlanganisiwe:

I-cold galvanizing empeleni iwukumboza ubuso bensimbi ngopende oqukethe i-zinc ephezulu ukuze kwakhiwe ungqimba oluvikelayo lokulwa nokugqwala, bese kuthi i-zinc powder ihlinzeke ngokuvikelwa kwe-cathodic ukuvimbela ukugqwala. Yingakho izakhiwo zensimbi ezifakwe i-cold galvanized zingavezwa ezindaweni ezinomswakama, ezinosawoti, nezinye ezigqwalisayo ngezinye izikhathi. Kodwa-ke, ungqimba lwe-zinc ludliwa isikhathi eside, futhi ukuvikelwa kokugqwala kwe-cold galvanizing ngokwayo "kunqunyelwe." Ukuze kwandiswe isikhathi sokuphila, kuthuthukiswe ukumelana nesimo sezulu, kuthuthukiswe ubuhle, futhi kuhlangatshezwane nezidingo ezithile zemvelo, ukupenda kuvame ukusetshenziswa ukubhekana nalezi ziphutha. Izici ezingokwemvelo zenqubo ye-cold-galvanizing zenza kube nzima ukusetshenziswa kwezembozo ezilandelayo (njengopende). Izinhlayiya ze-zinc embekweni zingathinta ukunamathela kopende, okuholela ezinkingeni ezifana nokuqhekeka, ukuqhekeka, kanye nokwehluleka kohlelo lopende ngaphambi kwesikhathi.

Ukuthi ukupenda kuyadingeka yini noma cha ezindaweni zensimbi ezibandayo zemibhoshongo yokuxhumana njengemibhoshongo yesignali ye-Ericsson kuncike ezidingweni zephrojekthi, indawo, kanye nezinhloso zokulungisa. Ngokuvamile, ukupenda okubandayo ngokwako kunikeza ukumelana nokugqwala, futhi ukupenda ngokuvamile akudingeki. Kodwa-ke, kumaphrojekthi amaningi emibhoshongo yokuxhumana, ukuze kwandiswe isikhathi sokuphila kwemibhoshongo noma ukuhlobisa noma izimo ezithile zemvelo, abantu bazosebenzisa upende ukuthuthukisa ukusebenza kokulwa nokugqwala. Ngokweminyaka yethu yesipiliyoni sokuhlinzeka ngopende kumaphrojekthi abo emibhoshongo yesignali, singabonisa ukuthi sibasiza kanjani ukuhlinzeka ngezixazululo zokumboza:

Ezimweni ezilandelayo, i-primer ingasuswa, futhi i-topcoat ingasetshenziswa ngqo.

Ikesi 1. Ukugqoka ngombala kuphela, akudingeki ukuvikelwa okwengeziwe kokugqwala.

Isibonelo: Umbhoshongo omusha wesignali; Isendlalelo esifakwe i-galvanized esisesimweni esihle; Ukugqwala okuphansi ezindaweni ezivamile (izindawo ezingcolisayo ezingezona ezogwini, ezingezona ezezimboni); Ukushintsha kombala nje (isb., obomvu nomhlophe wezimpawu zezindiza).

Noma kunjalo, kuyasebenza le mibandela elandelayo:

✅ Ingqimba eyomile neqinile ye-galvanized

✅ Ayinawoyela nothuli

✅ Ayinawo umhlwa omhlophe

✅ Umphezulu uphathwe kancane ukuze kuthuthukiswe ukunamathela

Icala2. Umbhoshongo wesignali utholakala endaweni engagqwali kakhulu.

Isibonelo: Izindawo zangaphakathi; ukungcola komoya okuphansi; hhayi eduze nogu; umswakama ojwayelekile; izinga eliphansi lokuguguleka kwe-galvanization ebandayo.

Kulesi simo: I-cold galvanizing ngokwayo ingahlangabezana nesikhathi esidingekayo sokumelana nokugqwala; i-topcoat isetshenziswa kakhulu ekuvikeleni umbala kanye ne-UV.

Ikesi 3. Insimbi entsha ebandayo ene-galvanized enekhwalithi enhle yokumboza i-zinc.

Uma:

Okuqukethwe kwe-zinc kuphezulu;

Ubukhulu be-zinc coating buhlangabezana nezidingo;

Ukwelashwa kwendawo kuhlangabezana nezimfuneko;

Akudingeki ukufaka i-primer.

Imikhiqizo Enconyiwe:

① Upende we-Acrylic

Izinzuzo: Ukunamathela okuhle, ukoma okusheshayo, imibala egqamile, izindleko eziphansi

② Upende we-Polyurethane

Izinzuzo: Ukumelana nesimo sezulu okungcono, ukumelana ne-UV, ukugcinwa kahle kombala, nokuphila isikhathi eside kwenkonzo.

Uhlelo lokumboza isicelo: Insimbi ebandayo eqinisiwe → I-Acrylic/PU topcoat

Kodwa-ke, ukusebenzisa i-primer kunconywa ezimweni ezilandelayo:

 Kungani kunconywa i-epoxy primer? Ngoba i-epoxy primer ayithathi indawo yesendlalelo se-zinc, kodwa kunalokho:

✅ Kuthuthukisa ukunamathela kwe-topcoat

✅ Ivala izimbobo engqimbeni ye-galvanized

✅ Kuvimbela usawoti we-zinc ukuthi ungaphazamisi i-topcoat

✅ Kuthuthukisa isikhathi sokuphila sokumelana nokugqwala. Manje njengoba sesiyazi ukuthi singawukhetha kanjani upende ofanele, ukusetshenziswa okufanele nakho kubalulekile.

Manje sesiyazi ukuthi singawukhetha kanjani upende ofanele, futhi ukusetshenziswa okufanele nakho kubalulekile.

Ukulungiselela Okungaphezulu:Ukulungiswa kwendawo efanele kubalulekile ukuze kuphumelele noma yimuphi umsebenzi wokumboza, ikakhulukazi lapho kubhekene nezindawo ezibandayo ezifakwe i-galvanized. Ngaphambi kokusebenzisa i-primer, indawo kumele ihlanzwe kahle ukuze kususwe ukungcola okufana nothuli, amafutha, noma uwoyela. Lokhu kungafezwa ngezindlela ezinjengokuhlanza ngomfutho ophezulu noma ukusebenzisa izihlanzi ezisekelwe ku-solvent.

Ngemva kokuhlanza, indawo engaphezulu kumele ihlolwe ukuthi ayinazo izimpawu zokugqwala noma umonakalo. Noma yiziphi izindawo ezigqwalile kufanele ziphathwe futhi zilungiswe ngaphambi kokupenda. Ngemva kokulungiswa, indawo engaphezulu kufanele ihlanzwe kancane ukuze kudalwe ukwakheka okuthuthukisa ukunamathela.

I-primer ebandayo ye-galvanized (i-topcoat isetshenziswa ngqo):

Qinisekisa ukuthi ungqimba olufakwe i-galvanized olubandayo alunawo amabala aqinile, alunawo ukugqwala okukhulu, ukuxebuka, kanye namabala kawoyela; susa uthuli, amafutha, usawoti, kanye nezinto ezingcolisayo; sanda kancane noma bhulashi ukuze uthuthukise ukunamathela kwe-topcoat.

1. I-Topcoat: Faka i-Acrylic/PU topcoat, ulawule ukujiya kwefilimu ngokulinganayo. Ngemva kokomisa, faka i-coat yesibili ukuze ufeze umbala ocacisiwe, ukujiya, kanye nezidingo zokuvikela. Kunconywa ukufaka amajazi amaningi amancane kunejazi elilodwa elijiyile ukuze ugweme izinkinga ezifana nokugoba noma ukungalingani kokumboza. Isikhathi esanele sokomisa kufanele sivunyelwe phakathi kwejazi ngalinye; bheka imininingwane yomenzi ngezikhathi ezithile.

2. Ukuhlola: Ngemva kokuba ungqimba lokugcina selomile, hlola indawo ependiwe ukuze ubone ukuthi kukhona amaphutha noma izindawo ezidinga ukulungiswa. Lungisa noma yiziphi izinkinga ngokushesha ukuqinisekisa ukuthi ungqimba lufana.

 Ukusebenzisa i-Primer (Uhlelo Lokumelana Nokugqwala Okuphezulu):

1. I-Primer: Okokuqala, faka i-primer ekhethiwe endaweni ebandayo ene-galvanized. Sebenzisa ibhulashi, i-roller, noma i-spray gun ukuqinisekisa ukuthi i-coating ilingana. Landela imiyalelo yomenzi mayelana nesikhathi sokomisa kanye nezikhawu zokufaka kabusha i-coating.

2. I-Topcoat: Ngemva kokuba i-primer isipholile ngokuphelele, faka upende we-acrylic PU wokulwa nokugqwala. Phakamisa ukufaka amajazi amaningi amancane kunejazi elilodwa elijiyile ukuze ugweme ukugoba noma ukungalingani kokugqoka. Isikhathi esanele sokomisa kufanele sivunyelwe phakathi kwejazi ngalinye; sicela ubheke imininingwane yomenzi ngezikhathi ezithile.

3. Ukuhlola: Ngemva kokuba ungqimba lokugcina selomile, hlola indawo ependiwe ukuze ubone ukuthi kukhona amaphutha noma izindawo ezidinga ukulungiswa. Lungisa noma yiziphi izinkinga ngokushesha ukuze uqinisekise ukuthi ungqimba lokugcina lufana.

Ngamafuphi, inkampani iForest Paint inolwazi oluningi kumaphrojekthi e-signal tower e-Ericsson, ithola imvume yezingubo zethu zokumboza ezinconywayo. Uma futhi unenkinga yokukhetha izingubo zokumboza ze-substrates ezibandayo, sicela uxhumane nethimba lokuthengisa leForest Paint ngokushesha ukuze uthole izixazululo zobuciko zokumboza.
