Upende phezu kwensimbi lashukumisa ngoba Ingaphandle ukusetshenziswa: izinhlobo kanye nezici

Ngo ukwakhiwa yesimanje, metal lashukumisa isetshenziswa kaningi. Yaba sibonga eyayithandwa nokwethenjelwa usizo. Kodwa enamathela zinc has bokwenza zayo, obonakaliswe ongaphakeme ukugqwala ukumelana. Material, nakuba ayengafiki kakhulu ngakho obala leli thonya, ezifana steel, kodwa uma ufuna ukufeza ukusebenza yesikhathi eside, kubalulekile ukuba beyomboza nge upende okhethekile.

The main izinhlobo upende galvanizing

Uma udinga upende phezu kwensimbi lashukumisa ukusetshenziswa ongaphandle, kubalulekile ukubhekana ezinye izinhlobo zawo ezinengilazi ezinjalo. Ziyakwazi:

• acrylic;
• vinyl;
• alkyd;
• iraba.

Acrylic Ngokuvamile kwenziwa ngesisekelo ezihogelwayo, zingatholakala ku ukudayiswa kodwa futhi izingoma amanzi bahlakazeka. Phakathi izithako ziqukethe izithasiselo anticorrosive. C ungakha ungqimba matte ebusweni usebenzisa upende acrylic. Izinzuzo main yalezi Izingxube yilezi: Ukumelana kakhulu emathonyeni zangaphandle, UV, adhesion kakhulu, kakhulu repellency amanzi, ukuqina kanye eziphansi.

Sibutsetelo izici alkyd upende galvanizing

Upende phezu kwensimbi lashukumisa ukusetshenziswa ongaphandle kungenziwa alkyd. Uma iqhathaniswa nezinhloko-zendaba engenhla, i nge wokuqala Ungakha ngiphele isicwebezelisi. Inqubo yokukhiqiza isebenzisa sombala asebenzayo anticorrosive. Phakathi kwezinye izinto, lezi upende ukusebenza oluvelele. Ngo anhlobonhlobo emakethe yesimanje ungathola izingoma alkyd angasetshenziswa endaweni yezimboni sezulu zasolwandle.

Sibutsetelo izici vinyl ezinengilazi for galvanizing

Upende phezu kwensimbi lashukumisa ukusetshenziswa ongaphandle futhi zingase zibe vinyl. Muva nje, waqala ukuthola ukuthandwa, ngenxa ezinye izakhiwo zalo. Upende has a ukumelana weathering futhi ubhekana ne okushisa aphakeme.

Isithombe phezu camera kungaba njalo nomthelela lokushisa 70 ° C, izinga lokushisa lingase okwesikhashana lakhuphuka lafika ku-90 ° C. Nokho, ikhava vinyl has ezithile, okuyinto obonakaliswe eziphezulu. Intengo ulungisiswa ezinye izimfanelo ezinhle ukuqina hlobo.

Uhlolojikelele izici iraba upende galvanizing

Upende phezu kwensimbi lashukumisa izinhlelo ongaphandle ngisho iraba enamathela elenziwe ngesisekelo acrylic. Phakathi timphawu letehlukene - kuyaqina okusezingeni eliphezulu. Ngemuva omiswe, ungqimba phezulu izinto ezinjalo lizofana iraba, ngaleyo ndlela cha umphumela okwesabisayo phezu amabutho mechanical, ezifana imithelela.

upende okunjalo ngoba metal evele okuhlala, amelana kuhlasela zamakhemikhali, kakhulu ibhekane kwezulu, ezahlukene nobungane kwemvelo futhi babe high izakhiwo zokuhlobisa.

Uphahla paintable metal lashukumisa

Uma udinga upende ukuze yensimbi lashukumisa, kuka ukupenda ophahleni, udinga ukuthi ucabange ngalokhu. I ezinengilazi ezivamile namuhla: udayi acrylic, uwoyela upende, kanye compounds nge anti-ukugqwala izakhiwo. Ukuze evele enjalo kufanele asebenzise udayi ekhethekile ngenxa yokuthi ebusweni galvanization ngaphezulu yokwenziwa eqhathaniswa metal ezivamile. Ngakho-ke, upende ingakhetfwa ikhumbula kuyaqina okusezingeni eliphezulu.

Lapho ekhetha upende ngoba evele lashukumisa, ochwepheshe ukweluleka ukuba banake matt udayi acrylic "Tsikrol" esesikhundleni esiphakeme adhesion umthamo futhi omuhle kakhulu anti-ukugqwala izakhiwo. Phakathi izinzuzo le nto imidwebo kufanele ezigqanyisiwe: Ukumelana weathering, ukubekezelelana omuhle kakhulu okushisa aphansi kanye nomswakama. Lokhu upende emva isicelo seyomile ngokushesha ngaphansi kwethonya emisebeni ultraviolet alupholi futhi amanzi oxosha. It lisetshenziswa ebusweni ezomile ngu spray, roller noma shayela. Uma kudingekile, ukwakheka kungenzeka buhlanjululwe nge butalatsetatom kuphela noma R646. enamathela ovikelayo okunjalo kakhulu yelula ukuphila wophahla lashukumisa.

Izibuyekezo kapende "Tsikrol"

Lokhu upende anti-ezonakalisayo ngoba metal lashukumisa kuyinto primer koqweqwe lwawo, okuyinto ekhiqizwa esekelwe acrylic inhlaka izithasiselo polymeric. I ezihogelwayo ukukhonza izinto njengoba ezengeziwe. Ngokusho amakhasimende, ingxube has a Ukusabalala eliphezulu ebusweni ngesineke.

Inhlanganisela uzokwazi ukuvikela ngisho nokusondelana emoyeni okunosawoti. Abathengi ukugcizelela ukuthi inhlabathi lula ukusebenza, anezakhi hydrophobic futhi kufanelekile hhayi nje ngobe kutawutfutfukisa steel zinc-camera, kodwa futhi izinhlelo endle, emiseleni, amapayipi lashukumisa, amaphrofayli, lukathayela, yensimbi nensimbi lashukumisa.

Isicelo ingxube lufanele lwenteke kulamazinga lalandzelako phezu bahlanza kusuka nokugqwala, futhi uma kufaneleka, njengoba kungenzeka uketshezi olusetshenziswa xylene noma ETHYL acetate.

Abathengi belulekwa ukuba afeze umsebenzi emazingeni okushisa ezisukela -10 kuya +50 ° C. Kufanele ulinde omiswe okuphelele 18 amahora, lokhu kuyiqiniso uma izinga lokushisa emoyeni ngaphandle + 20 ° C.

isiphetho

Ukusetshenziswa ngopende enamathela ekhethekile ezindaweni lashukumisa kuzosiza awuvikele ithonya elibi imvelo. Nokho, ukuqala zokukhwabanisa idatha, ochwepheshe batusa kuphela ngonyaka emva kokuphothulwa ukufakwa izakhiwo zophahla.

Phakathi nalesi sikhathi, umkhathi esizolungisa base for Umdwebo, bahlanza of nokugqwala futhi wenze ebusweni kancane olunzima. Uma ufuna ukwenza umsebenzi ngesikhathi esifushane, kungenzeka ukulungiselela ebusweni kwayona, kodwa kulokhu kubalulekile ukuzama ilimaze ungqimba ezondile galvanizing.
