Upende wephansi we-polyurethane uwupende wephansi osebenza kahle kakhulu osetshenziswa kakhulu ezakhiweni zezimboni, zezentengiselwano kanye nezomphakathi. Wakhiwe nge-polyurethane resin, i-curing agent, ama-pigment kanye nama-filler, njll., futhi unokumelana okuhle kakhulu nokuguguleka, ukumelana namakhemikhali kanye nokumelana nesimo sezulu. Izici eziyinhloko zopende wephansi we-polyurethane zifaka:
1. Ukumelana nokuguguleka okunamandla: Upende wephansi we-polyurethane unamandla okuguguleka futhi ufanelekela izindawo ezinabantu abaningi, njengezindawo zokusebenzela, izindawo zokugcina impahla kanye nezitolo ezinkulu.
2. Ukumelana namakhemikhali: Inokumelana okuhle nezinto ezahlukahlukene zamakhemikhali (njengamafutha, i-asidi, i-alkali, njll.), futhi ifaneleka ezindaweni ezifana nezitshalo zamakhemikhali kanye namalebhu.
3. Ukuqina okuhle: Upende wephansi we-polyurethane unezinga elithile lokuqina, elingamelana ngempumelelo nokuguquguquka okuncane komhlabathi futhi linciphise ukuqhekeka.
4. Ubuhle: Imibala ehlukene ingalungiswa ngokwezidingo. Ubuso bubushelelezi futhi kulula ukubuhlanza, okuthuthukisa ubuhle bendawo ezungezile.
Izinyathelo zokwakha
Inqubo yokwakha upende wephansi we-polyurethane iyinkimbinkimbi kakhulu futhi idinga ukulandela izinyathelo ezilandelayo:
1. Ukwelashwa kobuso obuyisisekelo
UKUHLANZA: Qiniseka ukuthi phansi akunawo uthuli, uwoyela nokunye ukungcola. Sebenzisa isibhamu samanzi esinomfutho ophezulu noma i-vacuum cleaner yezimboni ukuze uhlanze.
Ukulungisa: Lungisa imifantu kanye nemigodi emhlabathini ukuqinisekisa ukuthi isisekelo sibushelelezi.
Ukugaya: Sebenzisa umshini wokugaya ukuze upholishe phansi ukuze uqinise ukunamathela kwengubo.
2. Isicelo se-primer
Khetha i-primer: Khetha i-primer efanelekile ngokwesimo sangempela, ngokuvamile kusetshenziswa i-primer ye-polyurethane.
Ukuxubha: Sebenzisa i-roller noma i-spray gun ukuze ufake i-primer ngokulinganayo ukuqinisekisa ukumbozwa. Ngemva kokuba i-primer yomile, hlola ukuthi azikho yini izindawo ezingafanele noma ezingalingani.
3. Ukwakhiwa kwe-mid-coat
Ukulungiselela isembozo esiphakathi: Lungisa isembozo esiphakathi ngokwemiyalelo yomkhiqizo, ngokuvamile ufaka into yokwelapha.
Ukuxubha: Sebenzisa i-scraper noma i-roller ukuze ufake ngokulinganayo i-mid-coat ukuze wandise ukujiya kanye nokumelana nokuguguleka kwephansi. Ngemva kokuba i-mid-coat yomile, yihlanze.
4. Ukusetshenziswa kwe-Topcoat
Lungisa i-topcoat: Khetha umbala njengoba kudingeka bese ulungisa i-topcoat.
Indlela Yokusebenzisa: Sebenzisa i-roller noma i-spray gun ukuze ufake i-topcoat ngokulinganayo ukuqinisekisa ukuthi indawo ibushelelezi. Ngemva kokuba i-topcoat yomile, hlola ukuthi i-coating iyafana yini.
5. Ukulungiswa
Isikhathi sokulungisa: Ngemva kokupeyinta, kudingeka ukulungiswa okufanele. Ngokuvamile kuthatha izinsuku ezingaphezu kweziyi-7 ukuqinisekisa ukuthi upende waphansi upholile ngokuphelele.
Gwema ukucindezela okukhulu: Ngesikhathi sokupholisa, gwema ukubeka izinto ezisindayo phansi ukuze ugweme ukuthinta ikhwalithi yokugqoka.
Izinga Lokushisa Nomswakama: Naka izinga lokushisa elizungezile kanye nomswakama ngesikhathi sokwakha. Umphumela wokwakha uvame ukuba ngcono ngaphansi kwezimo ezingu-15-30℃.
Ukuvikelwa Kokuphepha: Amagilavu okuzivikela, imaski kanye nezibuko kufanele zigqokwe ngesikhathi sokwakha ukuqinisekisa ukuphepha.
