Ungazinceda njani iiprojekthi zeSignal Tower ze-Ericsson xa zisombulula ukugquma kwindawo ebandayo eneGalvani?

Kwicandelo lokwakha neziseko zophuhliso, ingakumbi kushishino lonxibelelwano, kubaluleke kakhulu ukukhetha inkqubo yokugquma efanelekileyo kwiziseko zophuhliso. Kwiiprojekthi ezinje ngokufakelwa kweenqaba ze-Ericsson, omnye umceli mngeni omkhulu kukukhetha inkqubo yokugquma efanelekileyo yentsimbi egqumayo. Ukugquma okubandayo yinkqubo egquma imiphezulu yentsimbi ngengubo etyebileyo ye-zinc ukuthintela ukugqwala. Nangona kunjalo, le substrate ithile inika imingeni eyahlukileyo ngokubhekiselele ekunamatheleni kokugquma kunye nokuqina. I-Forest Paint njengomthengisi wokugquma wenkqubo yokugquma iinqaba zesignali ze-Ericsson, siza kuhlola indlela yokukhetha inkqubo yokugquma efanelekileyo yokuthintela ukugqwala ukuqinisekisa ukuqina nokusebenza kweenqaba zesignali ze-Ericsson.

Ukuqonda iindawo ezibandayo ezigqunywe ngesinyithi:

I-cold galvanizing ngokuyintloko kukugquma umphezulu wentsimbi ngepeyinti enezinc eninzi ukwenza umaleko okhuselayo wokulwa nokugqwala, emva koko umgubo wezinc ubonelela ngokhuseleko lwe-cathodic ukuthintela ukugqwala. Yiyo loo nto izakhiwo zentsimbi ezine-cold-galvanized zinokuvezwa kwiindawo ezifumileyo, ezinetyuwa, nezinye izinto ezigqwalisayo ngamanye amaxesha. Nangona kunjalo, umaleko wezinc usetyenziswa ixesha elide, kwaye ukhuseleko lokugqwala lwe-cold galvanizing ngokwayo "lunqunyelwe." Ukwandisa ubomi, ukuphucula ukumelana nemozulu, ukuphucula ubuhle, kunye nokuhlangabezana neemfuno ezithile zokusingqongileyo, ukupenda kudla ngokusetyenziswa ukulungisa ezi ntsilelo. Iimpawu zendalo zenkqubo ye-cold-galvanizing zenza kube nzima ukusetyenziswa kwezambatho ezilandelayo (ezifana nepeyinti). Amasuntswana e-zinc kwi-coating anokuchaphazela ukunamathela kwepeyinti, okukhokelela kwiingxaki ezinje ngokuxobuka, ukuqhekeka, kunye nokungaphumeleli kwenkqubo yepeyinti ngaphambi kwexesha.

Nokuba ukupeyinta kuyimfuneko okanye akunjalo kwiindawo zentsimbi ezibandayo ezifakwe i-galvanized kwiinqaba zonxibelelwano ezifana neenqaba zesignali ze-Ericsson kuxhomekeke kwiimfuno zeprojekthi, indawo, kunye neenjongo zokugcinwa. Ngokubanzi, ukupeyinta okubandayo ngokwako kunika ukumelana nokugqwala, kwaye ukupeyinta akusoloko kuyimfuneko. Nangona kunjalo, kwiiprojekthi ezininzi zenqaba zonxibelelwano, ukwandisa ubomi benqaba okanye ukuhombisa okanye iimeko ezithile zendalo, abantu baya kusebenzisa ipeyinti ukuphucula ukusebenza kokulwa nokugqwala. Ngokweminyaka yethu yamava okubonelela ngeepeyinti kwiiprojekthi zabo zenqaba yesignali, singabonisa indlela esibanceda ngayo ukuba banikeze izisombululo zokugquma:

Kwiimeko ezilandelayo, i-primer ingasuswa, kwaye i-topcoat ingafakwa ngqo.

Ityala1. Umbala kuphela, akukho mfuneko yokhuseleko olongezelelweyo lokugqwala.

Umzekelo: Inqaba entsha yesignali; Umaleko obandayo okwimeko entle; Ukubola okuphantsi kwiindawo eziqhelekileyo (iindawo ezingezizo ezonxweme, ezingezizo ezemizi-mveliso); Ukutshintsha kombala (umz., obomvu nomhlophe kwiimpawu zeenqwelo-moya).

Nangona kunjalo, le miqathango ilandelayo iyasebenza:

✅ Umaleko we-galvanized owomileyo nozinzileyo

✅ Ayinaoyile nothuli

✅ Ayinawo umhlwa omhlophe

✅ Umphezulu uphathwe kancinci ukuphucula ukunamathela

Ityala2. Inqaba yesignali ikwindawo engenamhlwa kangako.

Umzekelo: Iindawo ezingaphakathi elizweni; ungcoliseko lomoya oluphantsi; akukho kufutshane nonxweme; ukufuma okuqhelekileyo; izinga elicothayo lokuguguleka kwe-galvanization ebandayo.

Kwimeko enjalo: I-cold galvanizing ngokwayo ingahlangabezana nobomi obufunekayo bokumelana nokugqwala; i-topcoat isetyenziselwa ikakhulu umbala kunye nokukhusela i-UV.

Ityala3. Intsimbi entsha ebandayo ene-galvanized enomgangatho olungileyo wokugquma nge-zinc.

Ukuba:

Umxholo weZinc uphezulu;

Ubukhulu bengubo ye-zinc buhlangabezana neemfuno;

Unyango lomphezulu luhlangabezana neemfuno;

Akufuneki ukuba ufake i-primer.

Iimveliso ezicetyiswayo:

① Ipeyinti ye-acrylic

Iingenelo: Ukunamathela kakuhle, ukomisa ngokukhawuleza, imibala eqaqambileyo, ixabiso eliphantsi

② Ipeyinti yePolyurethane

Iingenelo: Ukumelana nemozulu okungcono, ukumelana ne-UV, ukugcina umbala kakuhle, ubomi benkonzo obude.

Inkqubo yokufaka i-application coating: Intsimbi ebandayo egalelweyo → I-Acrylic/PU topcoat

Nangona kunjalo, ukusebenzisa i-primer kuyacetyiswa kwiimeko ezilandelayo:

 Kutheni kucetyiswa i-epoxy primer? Kuba i-epoxy primer ayithathi indawo yomaleko we-zinc, kodwa endaweni yoko:

✅ Yomeleza ukunamathela kwe-topcoat

✅ Ivala iimbobo kumaleko we-galvanized

✅ Ithintela ityuwa ye-zinc ekuchaphazeleni i-topcoat

✅ Iphucula ubomi bayo bonke bokumelana nokugqwala. Ngoku ekubeni siyazi indlela yokukhetha ipeyinti efanelekileyo, ukusetyenziswa kwayo ngokufanelekileyo kubalulekile.

Ngoku siyazi indlela yokukhetha ipeyinti efanelekileyo, kwaye ukusetyenziswa kwayo ngokufanelekileyo kubalulekile.

Ukulungiswa komphezulu:Ukulungiswa komphezulu ngendlela efanelekileyo kubalulekile kwimpumelelo yayo nayiphi na iprojekthi yokugquma, ingakumbi xa kusetyenzwa ngemiphezulu ebandayo ene-galvanized. Ngaphambi kokusebenzisa i-primer, umphezulu kufuneka ucocwe kakuhle ukuze kususwe izinto ezingcolisayo ezifana nothuli, igrisi, okanye ioyile. Oku kunokufezekiswa ngeendlela ezinje ngokucoca ngoxinzelelo oluphezulu okanye ukusebenzisa izicoci ezisekelwe kwisinyibilikisi.

Emva kokucoca, umphezulu kufuneka uhlolwe ukuba akukho zimpawu zokugqwala okanye umonakalo. Naziphi na iindawo ezigqwalileyo kufuneka zilungiswe ngaphambi kokuba zipeyintwe. Emva kokulungiswa, umphezulu kufuneka ucocwe kancinci ukuze kudalwe umzobo ophucula ukunamathela.

I-primer ebandayo ye-galvanized (isetyenziswa ngqo kwi-topcoat):

Qinisekisa ukuba umaleko ofakwe i-galvanized ebandayo awuguquki, awunayo i-rust enzima, ukuxobuka, kunye namabala eoyile; susa uthuli, i-grisi, ityuwa, kunye nezinto ezingcolisayo; sanda okanye ibrashi kancinci ukuze uphucule ukunamathela kwe-topcoat.

1. I-Topcoat: Faka i-Acrylic/PU topcoat, ulawule ubukhulu befilimu ngokulinganayo. Emva kokomisa, sebenzisa i-coat yesibini ukuze ufezekise umbala ochaziweyo, ubukhulu, kunye neemfuno zokhuseleko. Kucetyiswa ukuba ufake ii-coat ezininzi ezincinci endaweni ye-coat enye etyebileyo ukuze uphephe iingxaki ezinjengokugoba okanye ukungalingani kwe-coat. Ixesha elaneleyo lokomisa kufuneka livunyelwe phakathi kwe-coat nganye; jonga kwiinkcukacha zomenzi ngamaxesha athile.

2. Ukuhlolwa: Emva kokuba ulusu lokugqibela lomile, hlola umphezulu opeyintiweyo ukuze ubone naziphi na iziphene okanye iindawo ezifuna ukulungiswa. Sombulula naziphi na iingxaki ngokukhawuleza ukuqinisekisa ukuba isiphumo solusu siyafana.

 Ukusebenzisa iPrimer (Inkqubo yokuxhathisa ukugqwala okuphezulu):

1. I-Primer: Okokuqala, faka i-primer ekhethiweyo kumphezulu obandayo one-galvanized. Sebenzisa ibrashi, i-roller, okanye i-spray gun ukuqinisekisa ukuba i-coating ilingana. Landela imiyalelo yomenzi malunga nexesha lokomisa kunye nexesha lokuphinda u-coating.

2. I-Topcoat: Emva kokuba i-primer ipholile ngokupheleleyo, faka ipeyinti ye-acrylic PU anti-corrosion. Cebisa ukuba ufake ii-coat ezininzi ezincinci endaweni ye-coat enye etyebileyo ukuze uphephe ukugoba okanye ukugquma okungalinganiyo. Ixesha elaneleyo lokomisa kufuneka livunyelwe phakathi kwe-coat nganye; nceda ujonge iinkcukacha zomenzi ngamaxesha athile.

3. Ukuhlolwa: Emva kokuba ulusu lokugqibela lomile, hlola umphezulu opeyintiweyo ukuze ubone naziphi na iziphene okanye iindawo ezifuna ukulungiswa. Sombulula naziphi na iingxaki ngokukhawuleza ukuqinisekisa ukuba ulusu lokugqibela lufana.

Ngamafutshane, inkampani yeForest Paint inamava amaninzi kwiiprojekthi ze-signal tower ze-Ericsson, ifumana imvume yabo kwiingubo zethu ezicetyiswayo. Ukuba unengxaki nokukhetha iingubo ze-substrates ezibandayo ze-galvanized, nceda unxibelelane neqela lentengiso leForest Paint ngokukhawuleza ukuze ufumane izisombululo zobungcali zokugquma.
