As izifutho ze-polyurethaneziye zasetshenziswa kabanzi ekwakheni ukufakwa kwe-insulation kanye nokuvimbela amanzi futhi zifunwa kakhulu, abantu abaningi abazi ukuthi yini okufanele bayibheke nokuthi yini okufanele bayibheke lapho bethenga isifutho se-polyurethane.

Isifutho sekhwalithi ephezulu se-polyurethane kufanele sihlanganise: isistimu yokudlulisa impahla ezinzile, uhlelo olunembile lwemitha yempahla, uhlelo lokuhlanganisa impahla elinganayo, uhlelo oluhle lwe-atomisation lwempahla kanye nesistimu yokuhlanza impahla elula.Izinto zokufafaza kufanele zibe nokufudumeza, ukubamba, ukucindezelwa kanye nokuxuba nomthelela.

Lapho uthenga i-polyurethane sprayer, qiniseka ukuthi uhlola ngokucophelela izinga layo lokuzinza, ukusebenza kanye nobuchwepheshe besevisi yangemuva kokuthengisa, ngaphandle kwalokho kungaba yingozi kalula.Ake sibheke izinto okufanele uzinake lapho uthenga isifutho se-polyurethane.

1. Ukuzinza kwekhwalithi.Imishini yokucubungula izimboni isebenza ezindaweni eziyinkimbinkimbi futhi cishe ingasebenza isikhathi eside ngaphandle kokuma, ngakho ukuzinza kwekhwalithi yezinto zokusebenza kubaluleke kakhulu.

2. Ukusebenza.Kuya ngokuyinhloko ngesivinini kanye namandla emishini yokulayisha impushana, kanye nekhono lokucubungula ama-workpieces ayinkimbinkimbi.Kunzima ekuqaleni, ngakho qaphela futhi uzame ukufunda.

3. Isevisi yezobuchwepheshe iyingxenye yesevisi yangemuva kokuthengisa.Amakhasimende amaningi ngokuvamile adinga ochwepheshe abanolwazi nabasebenzi ukuze bakuqonde lokhu futhi umuntu ovamile wokuthengisa akakwazi ukuhlangabezana nale mfuneko, ngakho lokhu nakho kubalulekile.

Kungani imakethe ye-polyurethane sprayer ingakhula ngokushesha kuncike ezinhlelweni zayoizifutho ze-polyurethane.

1. Ukucindezela okuphezulu.Umfutho ophezulu we-athomu wenza i-polyurethane enamathelayo ibe yizinhlayiya ezincane kakhulu bese iwafafaza ezindongeni.Ngisho nezikhala ezincane zingafafazwa lapho ukugqoka kungasetshenziswa khona, okuvumela isibopho esiqinile phakathi kokugqoka kanye ne-substrate.

2. Ukwakhiwa akunqunyelwe ukuphakama.Ubude bezibhamu ezinde, amabanga amade wokufafaza futhi kulula ukufutha ngobude obumaphakathi

3. Indawo yokusebenza igcinwa ihlanzekile futhi icocekile.Upende awuhlakazeki yonke indawo lapho ufutha.

4. Ukusebenza kahle kokukhiqiza okuphezulu, okufanelekile ikakhulukazi ukwelashwa kokushisa kwe-adiabatic kwezinto ezinkulu nezibunjiwe, isivinini sokwenza ngokushesha kanye nokusebenza kahle kokukhiqiza okuphezulu.

5. Ifanele zonke izinhlobo zama-substrates.Noma ngabe indawo eyisicaba, eqondile noma engaphezulu, kungaba yindilinga, eyindilinga noma ezinye izinto eziyinkimbinkimbi ezinomumo ongajwayelekile, zingaphathwa ngokuqondile ngokufuthwa ngegwebu ngaphandle kokwenziwa kwesikhunta okumba eqolo.
