Njengamanje, opende bokumaka bemigwaqo bangaphandle basekelwe emanzini futhi bathuthuka ngokushesha. Bangaphezu kuka-90% opende abamaka bemigwaqo emazweni athuthukile njenge-United States, Germany, Spain, Sweden, neFinland basebenzisa imikhiqizo esekwe emanzini. Ngenxa yokuqalwa kwangaphambi kwesikhathi kwezingubo zokumaka emigwaqweni yangaphandle kanye nokuthuthuka ngokushesha kobuchwepheshe, kuye kwavela ukugqama komgwaqo we-nanometer, izingxenye ezimbili zokugqoka zokumaka umgwaqo, izigqoko zokumaka zomgwaqo ezine-pigment, nokunye.
Ezinyangeni ezimbalwa noma ngisho nezinsuku ezimbalwa ngemva kokukhiqiza, kuzoba nezinguquko ezinkulu ku-viscosity, isikhumba se-surface, njll., okuholela ekusebenzeni okungalungile kokufafaza kwe-coating kanye nomphumela omubi wokuvula; isikhathi esingabambeki asikwazi ukuhlangabezana nezidingo zangempela zokwakhiwa komgwaqo futhi sithinte ukwakhiwa Ubushelelezi bethrafikhi ngaleso sikhathi.
Manje sekunezimboni ezingaphezu kuka-100 ezinkulu nezincane zikapende omaka emgwaqweni e-China. Amafekthri amaningi amakhulu anamandla obuchwepheshe aqinile nawo aseqalile ukukhiqiza opende abamaka bomgwaqo abasekelwe emanzini. Ukuze kuqinisekiswe ikhwalithi yamapende omaka emgwaqeni, uMnyango Wezokuthutha wenze izimboni ezifanele. Amazinga akhuthaza ngamandla ukugcotshwa komgwaqo okusekelwe emanzini. Ukuhlaziywa kochwepheshe bezingubo zaphansi: Ngokuthuthuka kwemboni yezokuthutha zasemgwaqweni yaseChina kanye nokwanda okusheshayo kobunikazi bezimoto, isidingo sokumakwa kwezingubo sizokhula. Ngokukhula kokuqwashisa kwabantu ngokuvikelwa kwemvelo kanye nokwesekwa kwezinqubomgomo nemithetho kazwelonke, isidingo sezingubo zokumaka emgwaqeni ezisekelwe emanzini Inani likhulu.
imikhiqizo yezwe yami yokudweba izimpawu zomgwaqo esekelwe emanzini iye yasetshenziswa ekwakhiweni kwezikhumulo zezindiza, imigwaqo emikhulu, kanye neminye imiklamo, ephinde yadalula ezinye izingqinamba zobuchwepheshe. Izinkinga zamanje zezingubo zokumaka ezisekelwe emanzini ezikhanyayo zihlanganisa: ukuhuzuka okungekuhle kanye nokumelana nesimo sezulu, futhi zidinga ukunameka kabusha ngesikhawu 1a; ukumelana namanzi okungalungile kanye nokumelana ne-alkali, engakwazi ukuhlangabezana nezidingo zangempela zokucwiliswa komgwaqo emanzini; ukumelana nebala elimpofu, futhi ubuso bokumaka kulula ukuqoqa uthuli. Kuthinte i-retroreflective coefficient futhi kunciphise umphumela wokubonisa; ukungaqini kahle kwesitoreji.
