Ukufafaza nge-polyurethane ngokuvamile akunawo umthelela omncane ekwakhiweni kwasebusika.Nokho, lapho izinga lokushisa liphansi, ukunamathela kwesifutho se-polyurethane esisezingeni eliphansi kanye nodonga kubi, kubukeka njengokotini wekhekheba lezinyosi, futhi kuzowa kamuva.Namuhla ukukunikeza ukunaka ebusika ukwakhiwa kwe-polyurethane spraying insulation materials.

1. Ukwakhiwa kwe-PU spray kungcono kakhulu ukuqala ngezinga lokushisa: thola indlela yokushisa udonga, isimo esibi kakhulu isidingo sezinto eziningi zokushisa, noma zama ukwakha emini enkulu lapho izinga lokushisa liphakeme kancane.

2. Gwema ukuchithwa kokushisa futhi wenze umsebenzi omuhle wokuvimbela umoya ukuze ugweme ukwehla kokusebenza ngesikhathi senqubo yokukhipha amagwebu nokuphulukisa.

3. Ukubonakala kwezinto: qaphela ukuthuthukisa umsebenzi wokusabela, ukuxuba lapho ucabangela inani le-ejenti egwebu kanye nokuxhumana kokushisa okuphansi.

4. Izinga lokushisa lokwakha kufanele libe ngaphezu kuka-5, ukwakhiwa kufanele kugcine indawo yokwakha ingena umoya, zama ukungasebenzi ezimweni eziphansi zokushisa.

5. Izingxenye ezingasetshenzisiwe (ikakhulukazi ingxenye A), isivalo somphongolo kufanele simbozwe ngokuqinile ukuze kuvinjelwe ukumuncwa nokwelashwa komswakama, izinto ezixubile kufanele zidliwe phakathi nesikhathi esithile.

6. Njengoba izinga lokushisa liyancipha, izinga lokuchithwa kwe-mastic powder ku-polymer mortar linganciphisa, futhi isikhathi sokuxuba kufanele sinwetshwe lapho kulungiselelwa udaka lwe-polymer.Isilinganiso sikasimende kufanele sisetshenziswe phakathi kwebanga elishiwo, futhi impahla akufanele ixutshwe ngokweqile, ngaphandle kwalokho isikhathi sokuqinisa sizonwetshwa.

Okungenhla ukuthi ukwethule ukufuthwa kwe-polyurethane ezinyathelweni zokwakha zasebusika, lapho sibhekene nesimo sezulu esibandayo, sihlangene ukuze sihambisane nokwakhiwa kwemithethonqubo ukuze sizuze imiphumela oyifunayo.
