Ukuthuthukiswa kwezihlakazi (1)
Ama-dispersant ayizithasiselo ezingaphezulu ezisetshenziselwa ukuqinisa izinhlayiya eziqinile ezinkundleni ezifana nezinamathiselo, upende, ipulasitiki kanye nezingxube zepulasitiki. Esikhathini esidlule, izimbozo zazingadingi ama-dispersant. Izinhlelo ezifana nopende we-alkyd kanye ne-nitro zazingadingi ama-dispersant. Ama-dispersant awazange avele kwaze kwaba yilapho...Funda kabanzi -
Umsebenzi kanye nendlela yokukhuthazwa kokunamathela
Umsebenzi kanye nendlela yokusebenza komgqugquzeli wokunamathela Ngokuvamile abagqugquzeli bokunamathela banezindlela ezine zokusebenza. Ngayinye inomsebenzi kanye nendlela ehlukile. Indlela Yokusebenza Thuthukisa ukubopha ngomshini Ngokuthuthukisa ukungena kwamanzi kanye nokumanziswa kwengubo kuya ku-substrate, ingubo inga...Funda kabanzi -
Kuyini ukukhuthazwa kokunamathela?
Ngaphambi kokuqonda abagqugquzeli bokunamathela, kumele siqale siqonde ukuthi kuyini ukunamathela. Ukunamathela: Isimo sokunamathela phakathi kwendawo eqinile kanye nokuhlangana kwento ethile ngokusebenzisa amandla ama-molecule. Ifilimu yokumboza kanye ne-substrate kungahlanganiswa ndawonye ngokubopha ngomshini, ...Funda kabanzi -
Ukukhiqizwa kwemboni yephepha yomhlaba wonke kanye nokubuka konke kokusetshenziswa
Umthamo wokukhiqiza iphepha nebhodi lamaphepha Umkhiqizo wephepha nebhodi lamaphepha emhlabeni wonke ngo-2022 uzoba amathani ayizigidi ezingu-419.90, okungaphansi ngo-1.0% kunamathani ayizigidi ezingu-424.07 ngo-2021.
