Indlela Yokucacisa Ithangi Lokugcina Amakhemikhali
Kwadalwa ngo Ngokwamukisa
Ungayicacisa Kanjani Ithangi Lokugcina Amakhemikhali
Amathangi amakhemikhali ayahluleka uma ecaciswa ngesampula eyodwa esikhundleni somkhawulo wangempela womsebenzi. Indlela efanele ukuklama isimo esibi kakhulu kuyo yonke imixube yamakhemikhali, izinga lokushisa kanye nokugxila.
Cacisa ithangi lokugcina amakhemikhali ngokuchaza umkhawulo wokuhambisana (okwenziwa ikhemikhali entweni), ukugcinwa kwesibili, ukukhipha umoya, into eyakhiwe ngayo kanye nekhodi esebenzayo, usebenzisa amanani adlulele, hhayi isilinganiso.
Ukucacisa ithangi lokugcina amakhemikhali kusho ukukhetha into yalo, ukuma kwayo, ukugcinwa kwayo kanye nezici zokuphepha kusukela kuluhlu oluphelele lwamakhemikhali, izinga lokushisa, ukugxila kanye nezimo zokusebenza ezizobona ngempela.
Izici Eziyinhloko, Izingxenye Nezinhlobo
I-envelope yokuhambisana: Indwangu kufanele imelane namakhemikhali kuyo yonke imikhawulo yokugxila kanye nezinga lokushisa, hhayi endaweni eyodwa yesampula.
Ukugcinwa kwesibili: Ibhande, udonga olukabili noma indawo enolayini ibamba ukuvuza; ngokuvamile kuyalwa ngumthetho wamakhemikhali ayingozi.
Ukukhipha umoya: Kulinganiswe ukugcwalisa, ukuphefumula okushisayo kanye nanoma yimuphi umhwamuko, nokulawulwa kokukhishwa lapho kudingeka.
Ukukhethwa kwendwangu: Insimbi ehlanganiswe nge-enamel, i-FBE, i-stainless noma i-polyethylene ehambisana nekhemistri.
Ikhodi: Imithetho yendawo yokugcina nezemvelo, kanye nokuzamazama komhlaba nomoya lapho kufanele khona.
Izinhlelo zokusebenza nezimo zokusetshenziswa
Amakhemikhali ezinqubo zezimboni, amakhemikhali okuhlanza amanzi, ama-asidi, ama-alkali kanye nama-solvent agcinwa ezimbonini, ezinsizeni nasemafekthri.
Ukucatshangelwa kwezobuchwepheshe
Qala ku-envelope: ikhemikhali elinobungozi ku-20 C lingahlasela i-coating ku-60 C, futhi isisombululo esincishisiwe singaba sibi kakhulu kune-concentrated kwezinye izinto. Chaza izinga eliphakeme le-pH, izinga lokushisa, ukugxila kanye nanoma yikuphi ukungcola (ama-chloride, ama-solvent) futhi ucacise igobolondo kulelo envelope. Engeza isiqubulo sesibili esilingana nomthamo ogcwele wethangi emsebenzini oyingozi, kanye nokukhipha umoya okubhekana nokuphefumula okushisayo nanoma yimuphi umhwamuko.
Okwe-vitreous-enamel noma i-FBE steel, khumbula ukuthi izincibilikisi zivame ukuhlasela izigxivizo namagaskithi kuqala, hhayi indawo yokumboza, ngakho-ke cacisa ama-elastomer ahambisanayo. Hlanganisa ukukhethwa kwezinto ezisetshenziswayo nezinga lokwakheka kanye, uma kuwukudla, namazinga e-NSF/ANSI 61.
Izinzuzo Nezinkinga
Izinzuzo:
Ukucaciswa okusekelwe ku-envelope kuvimbela ukwehluleka okuvamile kokuklama ngesampuli esihle ngenkathi umsebenzi wangempela uhlasela ithangi ngokuthula. Ukugcinwa nokukhipha umoya kwengeza ukuphepha nokuhambisana.
Izingqinamba:
Ukuchaza umkhawulo wangempela kudinga idatha enhle yenqubo; okungaziwa kuphoqa ukuthi kukhethwe izinto ezigcina ngokuphepha (ezibiza kakhulu). Ukugcinwa kwesibili kwengeza indawo kanye nezindleko kodwa ngokuvamile akunakuxoxiswana ngakho kumakhemikhali ayingozi.
Ukuqhathanisa Nokukhetha Umhlahlandlela
Okokufaka kwe-Spec | Ukushayela |
Izinga lokushisa eledlulele | Izinga lezinto / ukumboza |
Izinga lokushisa nokugxila | Umkhawulo wokumelana |
Ikilasi lengozi | Ukugcinwa kwesibili |
Umhwamuko / ukuphefumula | Usayizi wokukhipha umoya |
Ikhodi yendawo | Idizayini nokuhlukaniswa |
Izinqubo ezingcono kakhulu nendlela yokukhetha
Yakha i-envelope yokuhambisana kusukela ku-pH embi kakhulu, izinga lokushisa, ukugxila kanye nokungcola, hhayi isampula elilodwa. Engeza isiqubulo sesibili esihambisana nekhodi kanye nokukhipha umoya okulungile, khetha into yegobolondo ku-envelope, futhi ucacise izimpawu ezihambisanayo. Hlanganisa nezakhiwo kanye, uma kuphuzwa, amazinga e-NSF/ANSI 61.
Cacisa ithangi lokugcina amakhemikhali kusukela ku-envelope yalo embi kakhulu, ngesiqubulo sesibili, ukukhipha umoya okulungile, into efanele kanye nokuhambisana nekhodi. Ukuklama ngesampula elijwayelekile yindlela amathangi amakhemikhali ehluleka ngayo.
Imibuzo Evame Ukubuzwa (FAQ)
Kungani kucaciswa esimweni esibi kakhulu, hhayi esilinganiselwe?
Amakhemikhali avame ukuhlasela izinto kakhulu ezingeni lokushisa noma ukugxila okwedlulele kunasesampuleni esilinganiselwe. Ukuklama ngokwesilinganiso esihle kuvumela umsebenzi wangempela ukuthi ugqwale noma ungene ethangini ngokuthula.
Kuyini ukugcinwa kwesibili?
Ibhande, udonga olukabili noma indawo enolayini ebamba ukuvuza noma ukuchitheka, ngokuvamile egunyazwa amakhemikhali ayingozi futhi ilinganiswe ngomthamo ogcwele wethangi.
Ingabe izincibilikisi zihlasela amathangi e-enamel?
Izincibilikisi ngokuvamile zihlasela izivalo nama-gasket ngaphambi kokumboza kwe-vitreous; cacisa ama-elastomer ahambisanayo futhi khumbula ukuthi ukumboza ngokwako akusebenzi kakhulu kumakhemikhali amaningi.
Kunqunywa kanjani ukuphuma komoya?
Ngezinga lokugcwalisa, ukuphefumula okushisayo (ukushintsha kwezinga lokushisa emini nasebusuku) kanye nanoma yimuphi umhwamuko okhipha ikhemikhali, kanye nokulawulwa kokukhishwa lapho umthetho udinga.
Yimuphi umgangatho osebenza kumathangi amakhemikhali?
Kuncike emsebenzini nendawo: imigomo yesakhiwo nokumboza ilawula igobolondo, imigomo yemvelo nokugcinwa ilawula ukugcinwa nokuhlukaniswa, kanti i-NSF/ANSI 61 isebenza kuphela uma kukhona ukuthintana namanzi okuphuzwayo.
