Isikhuselo seZiseko zoPhuhliso lweHlabathi: Ipeyinti yeFluorocarbon eSemanzini echasene nokubola kweTopcoat

*Ukwakhiwa kweMveliso:

Ipeyinti ye-fluorocarbon ephuma emanzini yipeyinti esebenza kakuhle kakhulu, enobuhlobo nokusingqongileyo esebenzisa i-resin ye-fluorocarbon ephuma emanzini njengento ephambili eyenza ifilimu. Ifumana ukuqina okuhle, ukumelana nemozulu, kunye nokumelana nokugqwala kweepeyinti ze-fluorocarbon zemveli ezisekwe kwi-solvent, ngelixa ukusebenzisa amanzi njengesinyibilikisi kunciphisa kakhulu umxholo we-VOC (i-volatile organic compound), ukuhlangabezana neemfuno zokhuseleko lwendalo esiluhlaza zanamhlanje kunye neemfuno zemveliso ekhuselekileyo. Ukusetyenziswa ngempumelelo kwetekhnoloji ephuma emanzini kwiipeyinti ze-fluorocarbon, ezibizwa ngokuba "ngukumkani weepeyinti," kubonisa incopho yetekhnoloji kushishino lwepeyinti zodonga zokwakha nezangaphandle.

*Iimpawu zeMveliso:

● Ubunzima obuphezulu befilimu, ukumelana nokuguguleka okuhle, ukuqina okugqwesileyo, kunye nokumelana nokuchasana.
● Ukumelana nemozulu okugqwesileyo kunye nokugcinwa kombala/ukukhazimla: Imelana ngempumelelo nokubola kwe-UV, ukubola kwemvula ene-asidi, kunye nokubola komoya nesanti; imelana nokubola kwetshokhwe kunye nokutshintsha kombala.
● Ukumelana kakuhle nokugqwala kunye neekhemikhali: Ukumelana kakuhle neekhemikhali ezininzi, izinyibilikisi kunye neegrisi. Ukwaleka okuxineneyo kuthintela ngempumelelo ukungena komswakama, ii-ion ze-chloride, kunye nee-sulfides, okubonelela ngokhuseleko oluhle kakhulu lokugqwala kwi-substrates zekhonkrithi kunye nezesinyithi.
● Ukuzicoca okugqwesileyo kunye nokumelana namabala: Amandla aphantsi omphezulu, okwenza kube nzima ukuba ukungcola kunamathele.
● Inobuhlobo nokusingqongileyo kwaye ikhuselekile: Isinyibilikisi esisekelwe emanzini, umxholo we-VOC ophantsi kakhulu, ayinatyhefu, ayinavumba, ayitshi, kwaye ayiqhumi, iqinisekisa ukusetyenziswa okukhuselekileyo.
●Ukusebenza kakuhle kunye nokunamathela: Ibonisa ukunamathela okuhle kakhulu kwiintlobo ngeentlobo zezixhobo, kuquka ikhonkrithi ecociweyo ngokufanelekileyo, isinyithi, iiphaneli ze-aluminium ezidityanisiweyo, kunye neengubo ezindala.

*Iinkcukacha zoBugcisa:

*Ukusetyenziswa kweMveliso:

Isetyenziselwa ukuthintela ukugqwala kwezixhobo zeekhemikhali, imibhobho kunye neendawo zesakhiwo sentsimbi kwiindawo ezinzima zoshishino ezingcolisayo. Ingapeyintwa kwizakhiwo zentsimbi, iiprojekthi zeebhulorho, izibonelelo zaselwandle, amaqonga okugqwala, amazibuko kunye needokhi, izakhiwo zentsimbi, ubunjineli bukamasipala, ii-guardrails ezikhawulezayo, ukuthintela ukugqwala kwekhonkrithi, njl.

*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.

Sitephu2: Sebenzisa iPrimer

Ngokwesiseko kunye nendawo ethile, khetha i-primer ehambelanayo (i-Epoxy Zinc-Rich Primer, i-Epoxy Zinc Phosphate Primer).

Inyathelo lesi-3: Faka ipeyinti yeFluorocarbon esekwe emanzini

Galela kancinci kancinci icandelo B (iarhente yokunyanga) kwicandelo A (ipeyinti ye-fluorocarbon esekwe emanzini), ngokucokisekileyo ngokwemilinganiselo echaziweyo (ngobunzima). Emva kokuxuba ngokupheleleyo, yiyeke ixube ime imizuzu emi-5-10 ukuze ivuthwe. Kwaye ipeyinti exutyiweyo isetyenziswe kwiiyure ezi-4 (ubomi bembiza). Emva koko brasha/rola okanye utshize, ukutshiza okungenamoya kunika ukusebenza okuphezulu kwaye kuvelisa umgangatho ophezulu wefilimu yepeyinti. Ukuba unezixhobo zobungcali kunye neendlela, kuya kuba ngcono. Ukusetyenziswa kwepeyinti yethiyori yi-0.2kg/m²/ipeyinti. (Ukusetyenziswa kokwenyani kunokwahluka ngokuxhomekeke kubume bomphezulu, ukuvuleka, 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 ukutshiza ngaphandle komoya ngamandla.
Ukuxubha/Ukuqengqeleka: Ubukhulu befilimu eyomileyo echaziweyo kufuneka bufikelelwe.

*Inkqubo yokugquma:

Sicebisa ukusebenzisa inkqubo epheleleyo "yokuvala iprimer + i-intermediate coat + i-water-based fluorocarbon topcoat" ukuze kufumaneke iziphumo ezilungileyo kunye nokusebenza kakuhle kweendleko.

I-PrimerImizekelo ibandakanya iprimer etyebileyo kwi-epoxy zinc kunye neprimer epoxy esekwe kwi-waterbased. Umsebenzi wayo oyintloko kukubonelela ngokhuseleko oluhle kakhulu lokulwa nokugqwala kunye nokunamathela.

Ingubo Ephakathi:Idla ngokuba yi-epoxy micaecous iron oxide coat esekwe emanzini. Iyandisa ubukhulu be-coating iyonke, isebenza njengomqobo ekuthinteleni umswakama kunye nezinto ezibangela ukubola, kwaye iphucula ukusebenza kokukhusela ngokubanzi.

Idyasi ephezulu:I-topcoat ye-fluorocarbon ibonelela ngomgca wokugqibela wokuzikhusela kwimozulu embi kunye nokugqwala, kunye nembonakalo entle efunekayo.

*Ukulumkela:

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

*Ukugcinwa kunye nexesha lokugcinwa:

▅ 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(18Liter/Ibhakethi); I-Hardener: 4Kg/Ibhakethi(4Liter/Ibhakethi) okanye eyenziwe ngokwezifiso.
