I-acetone, eyaziwa nangokuthi i-propanone, i-solvent evamile esetshenziswa kabanzi emkhakheni wemboni yamakhemikhali, imithi, ukuphrinta, nokunye.Kodwa-ke, ikhwalithi nentengo ye-acetone emakethe ingahluka.Ungasikhetha kanjani isiteshi sokuthenga esilungile?Lesi sihloko sizokwethula izakhiwo, izinhlelo zokusebenza, nemihlahlandlela yokuthengwa kwe-acetone ukukusiza ekuthengeni kalula i-acetone yekhwalithi ephezulu.
Ngokuthuthuka kwezimboni zamakhemikhali, ezemithi, zokunyathelisa, nezinye izimboni, i-acetone isiphenduke into encibilikayo evame kakhulu.I-acetone inezinto ezibonakalayo ezibonakalayo namakhemikhali ezifana nokuguquguquka nokuncibilika, okuyenza isetshenziswe kabanzi embonini yamakhemikhali, kwezokwelapha, ekunyatheliseni nakweminye imikhakha.Enqubweni yokuthengwa kwe-acetone, izinhlobo ezahlukene ze-acetone zingase zitholakale kuye ngezidingo ezithile zohlelo lokusebenza.Izinhlobo ezivame ukubonakala ze-acetone yizinga lezimboni kanye nebanga laselabhorethri.I-acetone yebanga laselabhorethri ifaneleka ezinkambini ezisezingeni eliphezulu, njengezemithi namalabhorethri.
Lapho uthengaI-ACETONE CAS 67-64-1 IKHALITHI NENANI ELIHLE KAHLE, ikhwalithi nokukhethwa kwabahlinzeki kubalulekile.Kunezinhlobo ezahlukahlukene ze-acetone ezitholakala emakethe, futhi ikhwalithi yazo ingahluka.Kulesi sihloko, sizonikeza iziphakamiso zokukhetha isiteshi sokuthenga ngokusekelwe kumthamo wakho wezidingo:
Ukuqonda imigudu yokuthenga
Enqubweni yokuthenga, kubalulekile ukuqonda kuqala izinzuzo nezinkinga zesiteshi ngasinye sokuthenga.Funda okuningi ngangokunokwenzeka mayelana nabahlinzeki, izinto zokusetshenziswa, izinqubo zokukhiqiza, ulwazi lwekhwalithi, neminye imingcele ebalulekile.Qhathanisa futhi ukhethe eziteshini ezihlukene zokuthenga.
Ukukhetha ukucaciswa okufanele kanye nezinga lekhwalithi elihlangabezana nezidingo zangempela
Ngokwezicaciso namazinga ekhwalithi ezimboni ezahlukene, khetha ngokunembile imikhiqizo ehlangabezana nezidingo zakho ezithile.Lokhu kuqinisekisa ukuthi imikhiqizo ingasetshenziswa ngempumelelo futhi kukhulisa inani lokuthenga kwakho.
Ukukhetha umphakeli ozinzile kubalulekile ohlelweni lokuthenga
Ukugcina ubudlelwano obuhle bokusebenza nabahlinzeki-mpahla kuyinzuzo kuzinzo lwesikhathi eside nokuthuthukiswa kwenkampani.Ukunquma izindleko zokugcina, izinkampani zidinga ukuqhathanisa amanani ngokucabangela izici ezihlukahlukene njengemikhiqizo ehlukene, abahlinzeki, kanye nokucaciswa.Ezokuthutha nazo ziyisici esibalulekile okufanele sicatshangelwe, kucatshangelwa izindleko nokusebenza kahle kokulethwa, kanye nomjikelezo othile wokukhiqiza ngokwenkontileka yomphakeli.
Ukuqonda isevisi yangemuva kokuthengisa kubalulekile ohlelweni lokuthenga njengoba kungathuthukisa ulwazi lomsebenzisi nokwaneliseka.Izinkampani kufanele zinake futhi zihlole ikhwalithi yesevisi yangemuva kokuthengisa yomphakeli.
Sengiphetha, lapho uthengai-acetone, izinkampani kufanele zicabangele amaphuzu angenhla.Imikhiqizo ye-acetone esezingeni eliphakeme inokubaluleka okubalulekile emikhakheni ehlukahlukene efana nezimboni zamakhemikhali, ezemithi, ukuphrinta, nokunye.Kuyalulekwa ukuthi uqonde ngokugcwele ulwazi oluphathelene nekhwalithi, intengo, neminye imingcele phakathi nenqubo yokuthenga, futhi ukhethe abahlinzeki abathembekile nabazinzile ngobuqotho kanye negama elihle.Lokhu kuzoqinisekisa ukuphathwa ngokushesha nangempumelelo kwanoma yiziphi izinkinga ezingase ziphakame phakathi nenqubo yokuthenga.
