I-Epoxy Anti Corrosive Primer esekwe emanzini (izinto ezimbini)

*Ingcaciso yeMveliso:

Yingubo enamacandelo amabini, eyenziwe nge-epoxy resin ephuma emanzini, ii-pigment kunye nezizalisi, izixhobo ezincedisayo, amanzi acocekileyo njalo njalo.

*Iimpawu zeMveliso:

● Ichasene nokugqwala kunye nokulwa nomhlwa: Yongeza imibala echasene nomhlwa ukuze uthintele ngokufanelekileyo ukufuma kunye neoksijini, ulibazise ukugqwala kweziseko zesinyithi, kwaye zifanelekile kwiindawo ezinomswakama;

● Ifilimu inokumelana kakuhle namanzi kunye nokusebenza kakuhle kokulwa nomhlwa;

● Ukunamathela okuqinileyo: Izinto ze-resin ze-epoxy zinokunamathela ngokuqinileyo kwiintlobo ngeentlobo ze-substrates (kuquka isinyithi kunye nekhonkrithi), zisombulula iingxaki zokusila kunye nokugqobhoza umaleko osisiseko;

*Ukusetyenziswa kweMveliso:

Ifanelekile kwi-primer yokulwa nokugqwala kunye nokulwa nomhlwa kwiindawo ezisisiseko ezifana nekhonkrithi, intsimbi, i-galvanized sheet, i-aluminium alloy, njl.njl., kwaye isetyenziswa kakhulu ekwakheni, kwiibhulorho, kwiipayipi ezingaphantsi komhlaba, kwizixhobo zoshishino, kwizixhobo ze-hydraulic, kwizixhobo zeekhemikhali, kwizixhobo zoomatshini, kwizakhiwo zentsimbi, kwizityalo zamandla obushushu, kwizibonelelo zamandla enyukliya, kwiinqaba zomoya kunye neeoyile ezahlukeneyo, kwiigesi ezicocekileyo kakhulu kunye neetanki zokugcina iikhemikhali eziphilayo.

*Iinkcukacha zoBugcisa:

Imigangatho yokwenziwa: HG/T4759-2014

*Unyango Lomphezulu:

Ukuqinisekisa ukuba ifilimu inamathela kwaye ikhuseleka ixesha elide ekugqwaleni, umphezulu we-substrate kufuneka ucocwe kakuhle kwioyile, umhlwa, isikali, ipeyinti endala, kunye nokungcola okukhululekileyo ngaphambi kokuba isetyenziswe. Imigangatho yokulungiselela kufuneka ihlangabezane noku kulandelayo:

Zonke iindawo eziza kugqunywa mazicoceke, zome kwaye zingangcolisi. Ngaphambi kokupeyinta, zonke iindawo kufuneka zihambelane ne-ISO_{8504: 2000}uvavanyo oluqhelekileyo kunye nokucutshungulwa.

Intsimbi enesikali iqhunyiswa kuSa_2.5ibakala, uburhabaxa bomphezulu yi-30-75μm, okanye i-pickled, i-neutralized kwaye i-passivated;

Intsimbi engena-okside itshiswe eSa_2.5ibakala, okanye ipolished ukuya eSt₃iklasi enevili lokugaya elinomoya okanye elinombane;

Iintsimbi ezigqunywe ngeprimer yeworkshop umonakalo wefilimu yepeyinti, umhlwa kunye nomhlwa omhlophe kwiprimer yepowder ye-zinc kufuneka zisuswe umhlwa kabini, umhlwa omhlophe ususwe uze upholishwe ukuya eSt.₃.

Ezinye iindawo Le mveliso isetyenziselwa ezinye izinto ezisetyenziswa phantsi komhlaba, nceda uqhagamshelane nesebe lethu lobugcisa.

*Imeko yoKwakha:

Ubushushu be-substrate abukho ngaphantsi kwe-5 ℃, kwaye ubuncinane bube ngaphezulu kwe-3 ℃ kunobushushu be-air dew point kwaye umswakama ohambelanayo ungaphantsi kwe-85% (ubushushu kunye nomswakama ohambelanayo kufuneka kulinganiswe kufutshane ne-substrate). Ukwakhiwa akuvumelekanga ngokungqongqo kwinkungu, ikhephu kunye nemozulu enomoya.

*Amanyathelo okwakha:

Inyathelo 1: Ukulungiswa komphezulu we-Substrate (IIsitshixoInyathelo)

Umgangatho wokulungiswa komphezulu umisela ngokuthe ngqo ukunamathela kunye nobomi befilimu yepeyinti.

Imiphezulu yesinyithi kufuneka isuswe amafutha kwaye ingabi nagqwala (ngokwemigangatho ye-Sa2.5 okanye ye-St3) ukuqinisekisa ukuba imiphezulu yesinyithi eza kupeyintwa kufuneka icoceke ngokupheleleyo, yome ngokupheleleyo, kwaye ingabi nazinto zingcolisayo ezifana neoyile, igrisi, uthuli, ityuwa, isikali, kunye nepeyinti endala ekhululekileyo. Akuvumelekanga ukufuma okubonakalayo okanye ukufuma.

Umphezulu ocociweyo kufuneka uhlangabezane nemigangatho yoyilo yokucoceka kunye noburhabaxa, kwaye ipeyinti kufuneka isetyenziswe ngokukhawuleza ukuthintela ukuphinda kuvele umhlwa okanye ungcoliseko lwesibini.

Inyathelo lesi-2: Faka i-Epoxy Primer esekwe emanzini

Emva kokuvula ibhakethi, xuba ngokulinganayo ngomxube wombane ude umbala kunye ne-viscosity zihambelane, galela kancinci i-component B (i-agent yokunyanga) kwi-component A (ipeyinti), ngokucokisekileyo ngokwemilinganiselo echaziweyo (ngobunzima). Emva kokuxuba ngokupheleleyo, yiyeke ixube ime imizuzu emi-5-10 ukuze ivuthwe. Kwaye i-mixed coating coating isetyenziswe ngaphakathi kweeyure ezi-4 (ubomi bembiza). Emva koko brasha/rola okanye utshize, i-Airless spray inika ukusebenza okuphezulu kwaye ivelisa umgangatho ophezulu wefilimu yepeyinti. Ukuba unezixhobo zobungcali kunye neendlela, iya kuba ngcono. Ukusetyenziswa kwepeyinti yethiyori yi-0.2kg/m²/coat. (Ukusetyenziswa kokwenyani kunokwahluka ngokuxhomekeke kubume bomphezulu, i-porosity, indlela yokufaka kunye nendlela yokusebenza.)

Phawula:

*Ukuba kuyimfuneko ukunciphisa ukuze kusetyenziswe ngokufanelekileyo, yongeza amanzi kancinci kancinci ngelixa uxuba. Umlinganiselo wokuxuba we-10-15%% ngobunzima. Ukunciphisa kakhulu kuya kuchaphazela kakubi ukwakheka kwefilimu, amandla okufihla, kunye nokuqina kwexesha elide. Lungisa i-viscosity ukuze ivumelane nendlela ethile yokufaka (ukubrasha, ukuqengqa, okanye ukutshiza).

* Ngaphambi kokuba ufake ijazi elilandelayo, qiniseka ukuba ijazi langaphambili licocekile, licocekile, lomile, kwaye alinazo zonke izinto ezingcolisayo.

* Kuphephe ukuxukuxa ngamandla ukuze uthintele ukungena kwamaqamza amaninzi.

*Indlela yokwakha:

Ukutshiza: Ukutshiza ngaphandle komoya okanye ukutshiza ngomoya. Kucetyiswa ukusebenzisa isitshiza esingenamoya esinamandla aphezulu.

Ukuxubha/Ukuqengqeleka: Ubukhulu befilimu eyomileyo echaziweyo kufuneka bufikelelwe.

*Ipeyinti Ehambelanayo:

Kucetyiswa ukusebenzisa ipeyinti ye-epoxy ephakathi esekwe emanzini efanelekileyo kunye ne-acrylic/polyurethane topcoat yamanzi ukwenza inkqubo yokugquma edibeneyo ethi “primer-intermediate-topcoat” ukufezekisa ukhuseleko lokugqwala lwexesha elide kunye neenjongo zokuhombisa kunye nokwandisa ubomi bengubo iyonke.

*Ukulumkela:

▶ Ubushushu bokwakha buyi-5℃-35℃ (Uhlengahlengiso oluthile lwenziwa ngokweempawu zemveliso, ukufuma ku-≤85%.

▶ Gcina umoya ungena kakuhle ukuze kube lula ukufuma kunye nokucocwa kwepeyinti.

▶ Zikhusele ekuqandeni ngexesha lokugcina.

▶ Izixhobo zokuzikhusela mazinxitywe ngexesha lokuqhumisa isanti

▶ Inkungu, imvula, ikhephu, umoya kunye nemvula akuvumelekanga ngokupheleleyo ukwakha.

*Ukugcina kunye nobomi bakho:

▅ Gcina kwindawo yokugcina izinto epholileyo, eyomileyo, nengenisa umoya ngaphakathi kubushushu obuyi-5-35 ℃, kuphephe ukubanda kunye nokukhanya kwelanga ngqo;

▅ Ubomi bomntu buziinyanga ezili-12. Ukuba iimveliso ezidlula ixesha lokugcina zingasetyenziswa emva kokuphumelela uhlolo.

*Iphakheji:

Ipeyinti: 20 Kg/Ibhakethi; Iarhente yokunyanga: 4Kg/Ibhakethi

Umlinganiselo oxutyiweyo wobunzima=5:1
