Ukufikelela ngokulula kwiikona kunye nezikhewu.Ngenxa yokusetyenziswa koxinzelelo oluphezulu kunye nokutshiza okungenamoya, ipeyinti yepeyinti ayinayo umoya, kwaye iipeyinti zinokufikelela ngokulula kwiikona, izikhewu kunye neengxenye ezingalinganiyo, ngakumbi kwizakhiwo zeofisi ezinemibhobho yomoya kunye nemibhobho yokulwa nomlilo.
Iingubo eziphezulu ze-viscosity zinokutshizwa, ngelixa ibrashi yezandla kunye nokutshiza umoya zisebenza kuphela kwiingubo eziphantsi ze-viscosity.Ngophuhliso loqoqosho kunye nokutshintsha kwembono yabantu, kuye kwaba yimfashini ukuhombisa udonga ngemigangatho ephakathi kunye nephezulu yangaphakathi kunye neengubo zodonga zangaphandle endaweni ye-mosaic kunye neethayile ze-ceramic emhlabeni.
Ipeyinti ye-emulsion yamanzi iye yaba yeyona nto ithandwayo ngaphakathi nangaphandle yokuhlobisa udonga ngenxa yokungabi natyhefu, ukucocwa okufanelekileyo, umbala ocebileyo kwaye akukho ngcoliseko yendalo.Kodwa ipeyinti ye-emulsion luhlobo lwepeyinti esekelwe emanzini kunye ne-viscosity ephezulu.Ngexesha lokwakha, abavelisi ngokubanzi banemiqathango engqongqo kakhulu yokuhlanjululwa kwepeyinti yokuqala ngamanzi, ngokubanzi i-10% - 30% (ngaphandle kwe-formula ekhethekileyo yokugqoka enokuthi idibanise amanzi amancinci ngaphandle kokuchaphazela ukusebenza kwengubo, eya kubhalwa. kwincwadi yemveliso).
I-dilution egqithisileyo iya kukhokelela ekubunjweni kwefilimu engalunganga, kwaye ukuthungwa kwayo, ukuchasana nokukhuhla kunye nokuqina kuya konakaliswa ngamaqondo ahlukeneyo.Idigri yomonakalo ihambelana ngokuthe ngqo kwi-dilution, oko kukuthi, i-dilution enkulu, imbi kakhulu umgangatho wefilimu.Ukuba iimfuno ze-dilution zomenzi zilandelwa ngokungqongqo, i-viscosity yepeyinti ye-emulsion iphezulu kakhulu kwaye ukwakhiwa kunzima.Ukuba i-roller coating, i-brush yokutshiza okanye i-air spraying isetyenziselwa ukwakhiwa, umphumo wepeyinti unzima ukuba unelisekile.Kumazwe angaphandle, eyona ndlela idumileyo kukusebenzisa umatshini wokutshiza ongenamoya woxinzelelo olukhulu xa kusakhiwa.
Ipeyinti yeLatex ayiqulathanga izinyibilikisi eziphilayo.Ayinayo kuphela i-solvent volatilization ngexesha lemveliso kunye nokwakhiwa, kodwa ayinakho ukungcola kwindawo engqongileyo, kwaye ukukhutshwa kwezinto eziphilayo ngexesha lokusetyenziswa kuphantsi kakhulu.Isixa sisonke se-VOC (i-organic volatile matter) ngokubanzi ingaphakathi kuluhlu oluvumelekileyo lomgangatho.Yinto ekhuselekileyo, ucoceko kunye nokusingqongileyo friendly umhombiso green isakhiwo umhombiso.
Ipeyinti ye-emulsion esekelwe emanzini inomoya omhle wokungena umoya kunye nokuchasana okunamandla kwe-alkali.Ngoko ke, akulula ukubetha i-blister xa kukho umehluko omkhulu phakathi komswakama wangaphakathi nangaphandle wengubo, kwaye ukugubungela akulula "ukuthuthumela" ngaphakathi.Kufanelekile ngokukhethekileyo ukupeyinta kwi-sement surface kunye ne-plaster surface yeendonga zangaphakathi nangaphandle zezakhiwo.Ipeyinti yeLatex isetyenziswa ngokubanzi ukuhombisa udonga lwangaphakathi nangaphandle kwezakhiwo ngenxa yoluhlu lwayo, umbala oqaqambileyo, ubunzima obulula kunye nokuhombisa ngokukhawuleza kwesakhiwo.
