Inkcazo kunye neempawu zePaint ye-Acrylic Enamel
Ipeyinti ye-enamel ye-acrylic luhlobo lokwambathisa apho i-acrylic resin iyeyona nto iphambili eyenza ifilimu. Ihlala inokumelana kakuhle nemozulu, ukumelana nokugqwala kweekhemikhali, kunye neempawu zokuhombisa. Ngokweziphumo zophando, ipeyinti ye-enamel ye-acrylic ineempawu ezibalaseleyo zokulwa nokugqwala, ukungangeni manzi, kunye neempawu ezichasene neoyile, kwaye inokukhusela ngokufanelekileyo umphezulu wezinto kwimpembelelo kunye nomonakalo wendalo yangaphandle. Ukongeza, njengepeyinti ye-acrylic enamacandelo amabini, ipeyinti ye-acrylic polyurethane enamel isebenzisa impendulo phakathi kwe--OH ye-acrylic kunye ne--NCO ye-polyurethane ukuze idibanise kwaye ilungise ifilimu, kwaye inokumelana okuhle kakhulu nokuguga, ukumelana nokuhlanjwa ngamanzi, iimpawu zomzimba, ukulungiswa kombala, kunye nokugcinwa kokukhanya.
Ukusebenza kokuthintela amanzi kwepeyinti ye-acrylic enamel
- Ipeyinti ye-acrylic ineempawu ezithile zokungangeni manzi kwaye ifanelekile kwiimeko ezifuna ukugqwala kunye nokumelana namanzi, njengezixhobo zesakhiwo sentsimbi, iibhulorho, iinqanawa, isinyithi, izikhongozeli, oomatshini bokwakha, iintlobo ezahlukeneyo zezithuthi zothutho, njl. Ukongeza, ipeyinti ye-acrylic polyurethane ikwanazo iimpawu zokuxhathisa amanzi kunye nokumelana ne-alkali, kwaye ifanelekile kumashishini anokukhukuliseka okukhulu.
- I-enamel ye-acrylic (efana nepeyinti ye-acrylic magnetic, ipeyinti ye-acrylic polyurethane magnetic) ingathathwa njengohlobo lwepeyinti eneempawu zokungena kwamanzi. Isici sayo sokungena kwamanzi siyenza ifaneleke kwiimeko apho kufuneka ukhuseleko ekungeneni kwamanzi, ngelixa ikwanazo neengenelo ezifana nokungagqwali kunye nokumelana nokwaluphala.
Isiseko esiphambili sokusebenza kokuthintela amanzi
I-enamel ye-acrylic (ekwaziwa ngokuba yipeyinti ye-acrylic) ineempawu ezintle zokungena kwamanzi, kwaye olu phawu luye lwasetyenziswa kakhulu kwaye lwaqinisekiswa kwicandelo lokulwa nokugqwala kwemizi-mveliso. Oku kulandelayo luhlalutyo oluneenkcukacha kunye neengcebiso zokusetyenziswa:
Isiseko esiphambili sokusebenza kokuthintela amanzi
- Iimpawu zezinto eziphathekayo
Ipeyinti ye-acrylic enamel isebenzisa i-acrylic resin njengesixhobo esiphambili sokwenza ifilimu. Ulwakhiwo lwayo lweemolekyuli luneempawu ze-hydrophobic, kwaye emva kokunyangwa, lunokwenza ifilimu exineneyo neqhubekayo, nto leyo ethintela ngempumelelo ukungena kwamanzi. Ezinye iimveliso zongeza izinto eziguqulweyo zerabha ye-polyethylene ene-chlorosulfonated okanye i-polyurethane (ezifana nepeyinti ye-acrylic polyurethane magnetic), nto leyo ephucula ngakumbi ukumelana namanzi kunye nokuthintela ukufuma.
Umzekelo, i-emulsion ye-acrylic esekwe emanzini ngokusebenzisa uyilo olukhethekileyo lweqela elingaphobiyo amanzi inokuthintela iimolekyuli zamanzi ukuba zingangeni kwi-substrate emva kokoma.
Iimveliso ezisekelwe kwisinyibilikisi (ezifana nepeyinti ye-acrylic metal magnetic) zinokumelana nokumanzi okugqwesileyo kwaye zifanelekile kwiindawo ezifumileyo ixesha elide.
- Ukuqinisekiswa kokusebenza
Uvavanyo lwelebhu lubonise ukuba emva kokuba imanziswe iiyure ezingama-24, ipeyinti ye-acrylic enamel ayinayo into yokuxobuka okanye yokuwa phezu komphezulu.
Kwiiprojekthi zangaphandle (ezifana neebhulorho, iinqanawa, kunye nezakhiwo zentsimbi), umsebenzi wayo wokungena kwamanzi unokumelana nokukhukuliseka kwamanzi emvula namanzi olwandle, ngaloo ndlela wandise ubomi be-substrate.
