Iyiphi Impahla Efanele Isitoreji Se-Acid Ne-Alkali
Kwadalwa ngo Ngokwamukisa
Iyiphi Into Efanele Ukugcinwa Kwe-Acid Ne-Alkali?
Umsebenzi wokugqwala uveza ubuthakathaka besisho esithi 'ukuvikela amakhemikhali'. Ukuvikela ngaso sonke isikhathi kuwukuvikela entweni ethile, ekugxiliseni nasezingeni lokushisa elithile. I-lining ehleka i-sulphuric acid engamaphesenti angu-98 ezingeni lokushisa elijwayelekile ingabhidlizwa yileso acid efanayo ehlanjululwe futhi ishisiswe, noma yisisombululo se-caustic okungekho muntu owayecabanga ukusikhuluma ngoba sasisetshenziselwa ukuhlanza kuphela.
Ukukhetha kuqala ngokusho igama lekhemikhali, ububanzi bokugxilisa, ububanzi bezinga lokushisa kanye nokungcola - futhi kwi-glass-fused-to-steel lokho kusho ukuphendula umbuzo owodwa kuqala: ingabe kukhona i-hydrofluoric acid noma i-caustic egxilile eshisayo emsebenzini? Lezo yizinto ezimbili zamakhemikhali ezihlasela inethiwekhi ye-silica yengilazi uqobo.
1. Kungani Kunezitha Ezimbili Zengilazi?
Ingilazi ehlanganisiwe iyinethiwekhi ye-silicate, futhi amakhemikhali amabili ajwayelekile ezimbonini ahlasela ngqo ama-silicate: i-hydrofluoric acid, ne-caustic eshisiwe egxilile. Konke okunye kumbuzo wesigaba, ukugxila kanye nezinga lokushisa.
· I-Hydrofluoric Acid: I-HF incibilikisa i-silica. Noma yimuphi umfudlana we-acid ophethe i-fluoride udinga ukufakwa okuhlukile - ngokuvamile i-polymer efanele - kungakhathaliseki ukuthi ingilazi isebenza kahle kangakanani kwenye indawo.
· I-Caustic Eshisiwe Egxilile: I-sodium hydroxide enamandla ezingeni lokushisa eliphezulu ihlasela inethiwekhi yengilazi. Ezingeni lokushisa elijwayelekile kanye nokugxila okulingene, i-GFS isebenza kahle; ngaphezu kwama-degree Celsius angaba ngu-60 nokugxila okuphezulu, hlola umsebenzi ngokucophelela.
· Lokho i-GFS Eyiphatha Kahle: Amasigaba ajwayelekile ahlanganisa cishe i-pH 3 kuya ku-11; izinhlelo ezikhethekile zezingubo ezintathu zandisa ububanzi buye phansi kuya ku-pH 1 ukuze kusetshenziswe i-acid enamandla.
· Ukushisa Kuxhumana Namakhemikhali: Wonke umkhawulo wokumelana namakhemikhali uncike ekushiseni, ngakho-ke inhlanganisela embi kakhulu - ukugxila okuphezulu ekushiseni okuphezulu - yiyo elawulayo.
2. Iziphi Izinto Ezivamile Eziqhathaniswa Kanjani?
Into ngayinye inendawo lapho iyimpendulo engcono kakhulu kanye nendlela yokwehluleka eyenza ingafaneleki kwenye indawo. Ukuqonda kokubili yikho konke ukukhethwa kwezinto.
· I-Glass-Fused-to-Steel: Ihle kakhulu kulo lonke ibhendi ye-acid ne-alkali, iqinile ngomshini, imelana nokuhuzuka, futhi iyasebenza kumabanga amakhulu. Ayifakwa yi-HF kanye ne-caustic egxilile eshisayo.
· Insimbi Engagqwali 316L: Iqinile ngama-asidi okushisa afana ne-nitric ne-phosphoric, futhi ihlanzekile. Isengozini yokugqwalwa kwe-chloride kanye nokuqhekeka kokugqwala kwengcindezi, futhi ayifanele i-hydrochloric acid.
· I-Fusion Bonded Epoxy: Ishibhile ekusebenzeni okulula, ngokuvamile cishe ku-pH 4 kuya ku-10, nophahla lokushisa oluphansi kakhulu kunolwengilazi.
· I-Polyethylene ne-Polypropylene: Ukumelana okumangalisayo ne-hydrochloric ne-hydrofluoric acids kanye ne-caustic, nophahla lokushisa ngokuvamile cishe ku-60 degrees Celsius kanye nokusebenza komlilo okulinganiselwe.
· Insimbi ye-Carbon: Ngokumangalisayo ifanele i-sulphuric acid egxilile engaphezu kwamaphesenti angama-93, lapho i-acid yenza insimbi ibe yi-passive, kanye neminye imisebenzi ye-caustic - kodwa kuphela ngaphakathi kwewindi elincane, elichazwe kahle.
3. Uyikhetha Kanjani Ngokwenzayo?
Bhala umsebenzi njengencazelo, hhayi njengegama. Izinto ezine eziguqukayo kanye nemibuzo emibili kuxazulula cishe wonke amacala.
· Shono Ikhemikhali kanye Nebanga Lokugxila: Faka izinto zokuhlanza kanye nezimo zokuphazamiseka, hhayi umgudu ojwayelekile wenqubo kuphela.
· Shono Isikhathi Sokushisa: Ukusebenza okujwayelekile, okuphezulu, kanye nezinga lokushisa ngesikhathi sokuhlanza noma ukufaka umusi.
· Khomba Izinto Ezingcolisayo: Ama-chloride, ama-fluoride, ama-solvent nama-oxidiser ashintsha impendulo ngisho noma ngamaqoqo amancane.
· Chaza Umphumela Wokwehluleka: Ukuvuza kwe-asidi egxilile endaweni yokuvikela amanzi angaphansi komhlaba kuthethelela into ehlukile kanye nezinga lokuvikela elihlukile kunalelo elisendaweni yezimboni ekude.
· Qinisekisa Ngemininingwane Yokuhlola: Cela umhlinzeki imininingwane yokumelana namakhemikhali futhi, lapho umsebenzi ungajwayelekile, imiphumela yokuhlola ukucwiliswa esigabeni sangempela sokumboza.

I-polyethylene / i-polypropylene | Kuhle kakhulu ku-HCl ne-HF | Kuhle kakhulu ku-caustic | Cishe ama-degree C angu-60 | Ukusebenza komlilo, ingcindezi, nokuchayeka ku-UV |
Insimbi ye-carbon | I-sulphuric acid egxilile engaphezu kwama-93% | Eminye imisebenzi ye-caustic ngaphakathi kwemikhawulo | I-ambient kuya kokulinganiselayo | Ama-acid ahlanjululwe anoma yiluphi uhlobo |
Isiqinisekiso Sobunjiniyela Nosekelo Lwephrojekthi
Lelo thanki ngalinye elilethwa yiShijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) lakhiwe ngokuhambisana ne-AWWA D103-09 kanye ne-EN 1090 ngokuqinisekiswa kwe-finite element yomthwalo wegobongo, uphahla kanye nama-nozzle, lincibilikiswa ku-820-930°C ngaphansi kokulawulwa kwe-ISO 9001 ne-ISO 45001, lihlolwa nge-holiday test ku-1500 V kuyo yonke indawo engaphezulu, futhi lihlanganiswa ngamabhawodi e-Grade 8.8 kanye ne-sealant eqinisekiswe umkhiqizi. Idatha yokumelana namakhemikhali yekilasi ngalinye lokumboza ihlinzekwa nesiphakamiso sentengo, futhi ukuhlolwa kokucwiliswa emanzini kusetshenziswa umswakama wangempela wenqubo kungenziwa lapho umsebenzi ungajwayelekile noma umphumela wokwehluleka mkhulu.
"Ayikho ithangi elimelana namakhemikhali, kukhona kuphela ithangi elimelana namakhemikhali akho. Shono ukugxila kanye nezinga lokushisa noma ukukhethwa kungaba ukuqagela."
Imibuzo Evame Ukubuzwa (FAQ)
Ingabe ingilazi encanyaniswe nensimbi ingagcina i-asidi enamandla?
Yebo kulo lonke ibhendi ebanzi. Amazinga ajwayelekile ahlanganisa cishe i-pH 3 kuya ku-11, futhi amasistimu akhethekile e-three-coat three-fire asetshenziselwa ukusebenza kwe-asidi eyedlulele eduze ne-pH 1. Okuhlukile i-hydrofluoric acid, ehlasela inethiwekhi ye-silica yengilazi uqobo.
Ingabe amathangi ane-glass lined angagcina i-caustic soda?
Yebo ekushiseni okujwayelekile nasekugxileni okulingene. I-caustic enamandla ekushiseni okuphezulu ihlasela inethiwekhi yengilazi, ngakho-ke imisebenzi engaphezu kwama-degree Celsius angama-60 ngokugxila okuphezulu idinga ukubuyekezwa okukhethekile futhi ingase idinge enye into.
Kungani i-hydrofluoric acid iyinkinga yengilazi?
I-hydrofluoric acid incibilikisa i-silica, okuyisisekelo sanoma yikuphi ukumbozwa kwengilazi noma kwe-enamel. Iyona asidi eyodwa evamile yezimboni engakwazi ukuphathwa i-glass-fused-to-steel, futhi imifudlana equkethe i-fluoride ivamise ukufakwa nge-polymer efanele esikhundleni salokho.
Ingini i-stainless steel ingcono kune-GFS kumakhemikhali?
Lapho umsebenzi uhlanganisa i-caustic eshisayo egxilile, i-hydrofluoric acid, noma lapho kudingeka khona ukuphela okucwebezelisiwe okuhlanzekile kanye nezinga lokushisa eliphezulu futhi amazinga e-chloride ephansi. Insimbi engagqwali nayo iyawina lapho amavolumu amancane kakhulu ethethelela umkhumbi owenziwe e-site.
