ethula:
Eminyakeni yamuva nje, ama-coatings asekelwe emanzini athole ukuthandwa ngenxa yobungane bemvelo kanye nokuqukethwe okuphansi kwe-volatile organic compound (VOC). Isithako esisodwa esibalulekile esidlala indima ebalulekile ekwakhiweni kokunamathela emanzini okusebenza kahle kakhulu izithasiselo ze-coalescent ezisebenza kahle kakhulu (HECs).
1. Qonda ama-coatings asekelwe emanzini:
A. Uhlolojikelele lwe-coating olusekelwe emanzini
b. Izinzuzo zemvelo zezingubo ezisekelwe emanzini
C. Izinselele ekwakhiweni kwezindwangu ezisebenza kahle emanzini
2. Isingeniso sezithasiselo ezisebenza kahle kakhulu zokwakha ifilimu (HEC):
A. Incazelo nezici ze-HEC
b. Ukuthuthukiswa ngokomlando nokuziphendukela kwemvelo kwe-HEC
C. Ukubaluleka kokuhlangana kwezingubo ezisekelwe emanzini
3. Iqhaza le-HEC enqubweni yokuhlanganisa:
A. Izindlela zokuhlanganisa kanye nokwenziwa kwefilimu
b. Umthelela we-HEC ekuhlanganeni kwezinhlayiyana nobuqotho befilimu
C. Thuthukisa ukunamathela nokuqina nge-HEC
4. Ukuthuthukiswa kokusebenza kwe-HEC:
A. Ukwakhiwa kwefilimu kanye nesikhathi sokumisa
b. Umthelela ekulevelini nasekubukekeni
C. Umphumela wokuqina nokumelana nokugqoka
5. Izici zokusimama kwe-HEC kuma-coatings asekelwe emanzini:
A. Ukuncishiswa kwe-VOC nomthelela kwezemvelo
b. Ukuhambisana nokulawula kanye namazinga omhlaba
C. Ukuhlaziywa komjikelezo wokuphila kwe-HEC esekelwe emanzini
6. Izicelo ze-HEC ezimbonini ezahlukahlukene:
A. Izingubo Zokwakha
b. Izingubo zezimoto
C. Industrial coatings
d. Izingubo zokhuni
7. Izinselelo nentuthuko yesikhathi esizayo:
A. Izinselele Zamanje Ekwakhiweni Kwe-HEC
b. Amathrendi asafufusa kanye nezinto ezintsha
C. Amathemba esikhathi esizayo we-HEC ekugqokeni okusekelwe emanzini
8. Izibonelo nezibonelo:
A. Ukusetshenziswa ngempumelelo kwe-HEC ezimeni zangempela
b. Ukuhlaziya okuqhathanisa nezinye izithasiselo ezakha ifilimu
C. Izifundo Ezifundiwe kanye Nezincomo Zokuthuthukiswa
Ekuphetheni:
Ukufingqa amaphuzu abalulekile okuxoxwe ngawo kulesi sihloko, sigqamisa indima ebalulekile ye-HEC ekuthuthukiseni ukusebenza nokusimama kwezingubo zokugqoka emanzini. Amathuba ocwaningo nokuthuthukiswa okuqhubekayo kule ndawo agqanyisiwe.
