● Ukumelana kakuhle nobushushu kunye nokufuma kunye netyuwa etshizwayo.

*Ukusetyenziswa kweMveliso:

Iipeyinti ze-polyurethane ezisetyenziswa emanzini zisetyenziswa kakhulu kwiingubo zokuhombisa zangaphandle ezineemfuno eziphezulu, ezifana noomatshini, iitanki zokuxuba, iibhulorho, iitanki zokugcina izinto, izikhongozeli, iinqanawa, ingakumbi izithuthi. Zingasetyenziselwa neengubo zeplastiki, zibonelela ngeengubo ezinemibala nezikhuselayo kwiimveliso zeplastiki ezifana neekhabhathi zemveliso ze-elektroniki, iithoyi, kunye nezixhobo zasekhaya.

*Iinkcukacha zoBugcisa:

*Unyango Lomphezulu:

Ukuqinisekisa ukuba ifilimu inamathela kwaye ikhuseleka ixesha elide ekugqwaleni, umphezulu we-substrate kufuneka ucocwe kakuhle kwi-oyile, 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.

Umphezulu ocociweyo kufuneka ucoceke, wome, ungabi naoyile, ungabi nathuli, kwaye upeyinte zingadlulanga iiyure ezi-6 emva kokugqunywa ngesanti ukuthintela ukugqwala komphezulu.

*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.

*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: Sebenzisa iPrimer

Ukuqinisekisa ukuba i-anticorrosion ingcono, cebisa i-primer enye ye-anti-rust, inokuphucula ukunamathela kwi-substrate kwaye ineempawu ezintle zokukhusela i-rust.

Inyathelo lesi-3: Faka ipeyinti yePolyurethane 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.)

*Ukuba kuyimfuneko ukunciphisa, xuba ngamanzi acocekileyo ngokwendlela yokufaka kunye nendlela (ukuxubha, ukuqengqa, okanye ukutshiza). Lungisa i-viscosity ukuze ihambelane nendlela ethile yokufaka.

* Umlinganiselo wokuxuba we-5-20% ngokobunzima. Ukuncitshiswa kakhulu kuya kuchaphazela kakubi ukwakheka kwefilimu, amandla okufihla, kunye nokuqina kwexesha elide.

* 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.

* Ixesha lokugquma kwakhona: Kwiindawo ezingcolisi kancinci: ipeyinti enye yeprimer + ipeyinti ye-midcoat emi-2 + ipeyinti ezimbini ze-topcoat; kwiindawo ezingcolisi kakhulu, yongeza ubukhulu bepeyinti.

*Indlela yokwakha:

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

Ukuxubha/Ukuqengqeleka: Ubukhulu befilimu eyomileyo echaziweyo kufuneka bufikelelwe.

*Ukulumkela:

▶ Ubushushu bokwakha yi-5℃-35℃ (Uhlengahlengiso oluthile lwenziwa ngokweempawu zemveliso, ukufuma yi-≤80%.

▶ 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: 20kg/ibhakethi, I-Hardener/iarhente yokunyanga: 4Kg/ibhakethi okanye wenze ngokwezifiso
