Ipeyinti ye-alkyd enamel
Xa senza uyilo lokuhombisa ikhaya, kufuneka kuqwalaselwe izinto ezininzi. Enye yezinto ezibalulekileyo kukukhetha ipeyinti. Kukho iimfuno eziphezulu kakhulu zohlobo, umbala, umgangatho, njl.njl. wepeyinti. Kwaye ipeyinti ye-alkyd enamel, njengohlobo olutsha lwepeyinti, ngokuqinisekileyo iya kutsala ingqalelo yomntu wonke.
I-enamel ye-alkydyimpahla yepeyinti ekhazimlayo, ecacileyo kakhulu kwaye iqinile kakhulu, yenziwe nge-alkyd resin, i-pigment, i-hardener kunye ne-solvents. Le ngubo ineenzuzo zokucoca umoya, ukuthintela ukungunda, ukuthintela ukugqwala, ukuthintela amanzi, ukuthintela ukungcola, ukuthintela ukukrwitshwa, kunye nokwahlula i-formaldehyde, phakathi kwezinye.
Umsebenzi wokulungiselela
Apha, siza kugxila ekuxoxeni ngendlela ipeyinti ye-alkyd enamel ethintela ngayo umhlwa.
Izinto ezisetyenziswa kwi-alkyd enamel ziquka i-alkyd resin kunye ne-hardener.
- Impembelelo yeekhemikhali phakathi kwezi zinto zimbini iya kubangela ukwakheka komphezulu onomsebenzi wokuthintela umhlwa kwifilimu yepeyinti.
- I-enamel ye-alkyd inokuqina okuhle kakhulu kunye nokumelana nokugqwala. Ukuqina kunye nokunamathela kwefilimu yepeyinti kunokuhlangabezana neemfuno zokuthintela ukugqwala ezikumgangatho ophezulu.
- Ubunzima obukhulu be-alkyd enamel bunokumelana ngempumelelo nokuguguleka kwamandla angaphandle kunye nemikrwelo, bukhusela umphezulu wezinto ezisisiseko ekungcoleni kwaye buyolule ixesha lokuphila kwengubo.
Nangona ipeyinti ye-alkyd enamel ineempawu ezilungileyo zokuthintela umhlwa, ayilohlobo oluthile lwepeyinti yokuthintela umhlwa. Ke ngoko, xa uyila umhombiso wekhaya, umntu kufuneka enze ukhetho olufanelekileyo malunga nohlobo kunye nophawu lwepeyinti ngokusekelwe kwiimeko ezithile. Ukuba indlu yakho ikwindawo enomswakama okanye ikwindawo engaselunxwemeni, kuyacetyiswa ukuba ukhethe iipeyinti ezineempawu zokuthintela umhlwa ukukhusela indlu kwiingozi ezinokubakho. Xa ukhetha iipeyinti, umntu kufuneka akhethe neepeyinti ezifanelekileyo ngokusekelwe kuhlobo kunye neemfuno ze-substrate.
Ukusebenza kokuthintela umhlwa kwepeyinti ye-alkyd enamel
I-alkyd enamel luhlobo oluqhelekileyo lwepeyinti oluneempawu ezintle zokuthintela umhlwa, nto leyo eyenza ukuba isetyenziswe kakhulu njengepeyinti ekhusela umhlwa. Umgaqo ophambili wokuthintela umhlwa wale peyinti kukwenza ifilimu ekhuselayo kumphezulu. Le filimu inokuthintela ngokufanelekileyo ukufuma, ioksijini, kunye nezinto ezirhabaxa ukuba zingangeni kumphezulu wesinyithi, ngaloo ndlela ifezekisa injongo yokuthintela umhlwa. Ukongeza, i-alkyd enamel ikwanayo ne-adhesive elungileyo kunye nokumelana nemozulu, kwaye inokugcina ukusebenza okuzinzileyo kwiindawo ezahlukeneyo.
Ubudlelwane phakathi kwezinto zepeyinti ye-alkyd enamel kunye nomsebenzi wayo wokuthintela ukugqwala
Ayizizo zonke iipeyinti ze-alkyd enamel eziqulethe iipigments ezichasene nomhlwa, ngoko ke azinakubonelela ngokhuseleko lokulwa nomhlwa. Xa usebenzisa iipeyinti ze-alkyd enamel, kuyimfuneko ukujonga ngononophelo ukwakheka kunye nenjongo yokusetyenziswa kwemveliso ukuqinisekisa ukuba ineempawu zokulwa nomhlwa. Iipeyinti ze-alkyd enamel ezahlukeneyo zineempawu ezahlukeneyo zokulwa nomhlwa kunye nobomi benkonzo, obuxhomekeke kwiipigments ezichasene nomhlwa ezinazo kunye nobukhulu bomgqumo.
Umahluko phakathi kwepeyinti ye-alkyd enamel kunye nezinye iipeyinti ezichasene nomhlwa
Ipeyinti yemagnethi yenziwe ngevarnish njengesixhobo esisisiseko kwaye ilungiswa ngokugaywa ngeepigment. Emva kokuba ipeyinti yomile, iveza imibala yokukhanya kwemagnethi kwaye inomphezulu oqinileyo. Iintlobo eziqhelekileyo ziquka ipeyinti ye-phenolic magnetic kunye nepeyinti ye-alkyd magnetic. Zifanelekile kwi-mesh yefestile yesinyithi kunye nezinye izinto. Ipeyinti ye-anti-rust inokukhusela umphezulu wesinyithi kwi-chemical okanye electrochemical corrosion ebangelwa ngumoya kunye namanzi olwandle. Yahlulwe ngokubanzi kwiindidi ezimbini: ipeyinti ye-physical kunye neye-chemical anti-rust. Ipeyinti yemagnethi ibandakanya i-zinc etyheli, i-iron red epoxy primer. Ifilimu yepende iqinile kwaye ihlala ixesha elide, ine-adhesion elungileyo. Ukuba isetyenziswa kunye ne-ethylene phosphating primer, inokuphucula ukumelana nobushushu kunye nokumelana netyuwa. Ifanelekile ukusetyenziswa njengesiseko sezinto zesinyithi kwiindawo eziselunxwemeni nakwiindawo ezishushu.
Ipeyinti ye-alkyd enamel ingathathwa njengepeyinti ebalaseleyo yokulwa nomhlwa, kodwa ayizizo zonke iipeyinti ze-alkyd enamel ezineempawu zokulwa nomhlwa. Ngaphambi kokusetyenziswa, kuyimfuneko ukukhetha imveliso ngononophelo kwaye ulandele imiyalelo yokusetyenziswa kunye nokugcinwa kwayo ukuqinisekisa impembelelo yayo yokulwa nomhlwa kunye nobomi benkonzo.
