Izici zokuphepha kwemvelo nezici zikayinki osuselwe emanzini

Uyinki osuselwe emanzini, njengento emisha embonini yokunyathelisa, uthole ukunakwa okukhulu ngenxa yezici zokuphepha kwemvelo kanye nezinzuzo ezihlukile. Ngokuphambuka koyinki abavamile abasekelwe kuncibiliki, ukuguqulwa kukayinki osuselwe emanzini kusekusetshenzisweni kwawo amanzi njengesixazululi esiyinhloko, esihambisana nephesenti elincane lotshwala (cishe u-3% kuya ku-5%), okuthuthukisa kakhulu ukuphepha kanye nobungane bemvelo. wezinto zokunyathelisa kuyilapho kuthuthukisa ngendlela emangalisayo indawo ezungezile nokusebenza kahle kwemisebenzi yokunyathelisa.

Okokuqala, izifakazelo zemvelo zikayinki osuselwe emanzini zibonakala ngokungabi bikho kwayo kwezinhlanganisela zemvelo ezishintshashintshayo (VOCs), njenge-toluene ne-ethyl acetate, evame ukutholakala kumayinki asekelwe ku-solvent. Ngokunciphisa ukukhishwa kwe-VOC, uyinki osuselwe emanzini unciphisa umthelela wawo kukhwalithi yomoya, okunomthelela ekwehliseni ukungcoliswa komoya. Ngaphezu kwalokho, ukungabi bikho kwephunga elibi ezindaweni zokunyathelisa kudala indawo yokusebenza emnandi, ngaleyo ndlela kuthuthukisa ukunethezeka nokukhiqiza kwabasebenzi.

Okwesibili, ukwamukelwa kukayinki osekelwe emanzini kuhumusheka ekunciphiseni ukusetshenziswa kwezinsiza kanye nezindleko eziphansi zokuvikela imvelo. Imvelo evumelana nemvelo yezingxenye zayo yenza lula izindlela zokulahla imfucuza futhi inciphise izindleko ezihambisanayo, inciphise imithwalo yezomnotho emabhizinisini futhi ihambisane nemithethonqubo yezemvelo eqina kakhulu emhlabeni wonke. Ukwengeza, isici esingashi sikayinki osekelwe emanzini kunciphisa kakhulu izingozi zomlilo phakathi nenqubo yokuphrinta, okuqhubekisele phambili ukuqinisa ukuphepha komkhiqizo.

Ngokwezici zobuchwepheshe, uyinki osuselwe emanzini ubonisa ukuguquguquka okukhethekile kokuphrinta nokuzinza. I-viscosity yayo ephansi ikhuthaza ukugeleza okuphezulu nokudlulisa izakhiwo emishinini yokunyathelisa, yenza lula ukunyathelisa ngesivinini esikhulu, futhi yome ngokushesha, yakha ifilimu ye-inki enokumelana okuhle kakhulu kwamanzi, ukumelana ne-alkali, nokumelana nokugqokwa okuvelele, iqinisekisa izinga lokulondolozwa kwesikhathi eside kanye nokubukwayo. ukukhanga kwemikhiqizo ephrintiwe. Kungakhathaliseki ukuthi umbhalo olula noma imidwebo yombala eyinkimbinkimbi, uyinki osuselwe emanzini uletha imibala ecebile, izendlalelo ezihlukile, nokucwebezela okuphezulu, okuhlangabezana nesidingo semboni yokunyathelisa yesimanje sokukhishwa kwesithombe sekhwalithi ephezulu.

Kafushane, u-inki osekelwe emanzini, nezici zawo ezilungele imvelo, eziphephile, nezisebenza kahle, usuzuze ukusetshenziswa okusabalele nokuqashelwa kuwo wonke umkhakha wokunyathelisa emhlabeni jikelele. Njengoba ukuqwashisa ngemvelo kuqhubeka nokudlondlobala emhlabeni wonke, u-inki osekelwe emanzini uya ngokuya eba yinketho ekhethwayo yezinto zokunyathelisa, eqondisa uguquko oluluhlaza embonini yokunyathelisa.
