Ipeyinti ye-Epoxy esekwe emanzini esebenza kakhulu: Ipeyinti yokulwa nokugqwala

*Ukwakhiwa kweMveliso:

Ipeyinti ye-epoxy esekwe emanzini yipeyinti enezinto ezimbini, esebenza kakhulu, enobuhlobo nokusingqongileyo echasene nokubola, yenziwe yi-epoxy resin esekwe emanzini eguquliweyo, ii-pigments ezichasene nokugqwala, izizalisi, izongezo kunye namanzi acocekileyo, njl. Kwaye idibanisa ukunamathela okuhle kakhulu, ukumelana neekhemikhali, kunye nokungagqwali kwepeyinti ye-epoxy yendabuko kunye neenzuzo ezibalulekileyo zepeyinti esekwe emanzini, njengokhuseleko lokusingqongileyo kunye ne-VOC ephantsi kakhulu. Lukhetho olubalulekileyo kwizicelo zokukhusela ukugqwala ezifana neenqanawa, iibhulorho, kunye nezakhiwo zentsimbi.

*Iimpawu zeMveliso:

● Ukwaleka kokukhusela okusingqongileyo, kusetyenziswa amanzi njenge-VOC encinci kakhulu, i-VOC ephantsi kakhulu, indawo yokugcina nokwakha ekhuselekileyo nezinzileyo, ayitshisi kwaye ayiqhumi.

● Ukusebenza kakuhle kakhulu kokulwa nokugqwala kunye nokulwa nokugqwala.

● Ukunamathela okuqinileyo, ukumelana okugqwesileyo kwe-asidi kunye ne-alkali, ukumelana nesinyibilikisi, kunye nokumelana okugqwesileyo kwemozulu.

● Ukumelana neekhemikhali: Ifilimu yepeyinti ixinene kwaye imelana ngempumelelo nokugqwala kwamanzi, ityuwa, igrisi, iziseko ezithambileyo kunye neeasidi.

● Ukumelana nokuguga okwenziweyo okunamandla, ukumelana namanzi okuhle, ukuguquguquka okuhle kwefilimu yepeyinti, ukumelana okunamandla kwempembelelo, kunye nokhuseleko olugqwesileyo lwesiseko.

*Ukusetyenziswa kweMveliso:

Ifanelekile ukhuseleko lokugqwala oluphakathi nolunzima lwexesha elide lwezakhiwo zentsimbi kunye nezixhobo zoomatshini kwiindawo eziphakathi ukuya kwezinzima zokugqwala, kwaye ingasetyenziselwa nezakhiwo zolondolozo. Isetyenziswa kakhulu kukhuseleko lokugqwala kwemizi-mveliso kwiibhulorho, izakhiwo zokugcina impahla zentsimbi, izakhiwo zentsimbi kumashishini e-petrochemical, umbane, kunye ne-metallurgical, imibhobho, iitanki zokugcina (iindonga zangaphandle), izixhobo ezixhasayo, kunye nezinye izicelo zoshishino. Ikwasetyenziselwa ukugquma ukhuselo lokugqwala kwizicelo zothutho ezifana noomatshini bezibuko, oomatshini bokwakha, izithuthi zoshishino, iilocomotive, iikhonteyina, kunye neemoto zokuthutha impahla. Ingasetyenziselwa nokhuseleko lokugqwala kwezakhiwo zangaphakathi ezifana namagumbi eenjini zeenqanawa, izakhiwo eziphezulu, kunye neetanki ze-ballast.

*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.

*Iinkcukacha zoBugcisa:

Imigangatho yokwenziwa: HG/T 4759-2014

*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 lokucoceka kunye noburhabaxa, kwaye ipeyinti kufuneka isetyenziswe ngokukhawuleza ukuthintela ukuphinda kuvele umhlwa okanye ungcoliseko lwesibini.

Inyathelo lesi-2: Sebenzisa iPrimer

Ukuqinisekisa ukuba i-rust iyasebenza ngcono, cebisa ukuba ufake i-primer enye ye-anti-rust, kwaye ikwaphucula ukunamathela kwi-substrate.

Inyathelo lesi-3: Faka ipeyinti ye-Epoxy 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, 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 buyi-5℃-35℃ (Uhlengahlengiso oluthile lwenziwa ngokweempawu zemveliso, ukufuma ku-≤85%.

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

▶ Ukuhambelana kufuneka kuqinisekiswe xa kudityaniswa nepeyinti esekwe kwisinyibilikisi (kucetyiswa uvavanyo lwendawo encinci).

(kucetyiswa uvavanyo lwendawo encinci).

▶ 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: 4 kg/Ibhakethi okanye Yenza ngokwezifiso

Umlinganiselo oxutyiweyo wobunzima=5:1
