Emisa Lefohla: 7 Linnete Tse Hloekileng Mabapi le Moemeli ea Foaming bakeng sa Phekolo ea Metsi a Litšila ho Ready Mix Plants

Bothata ba hau ba Foam bo mpe ho feta kamoo u nahanang

Mona ke lipalo-palo tse bolokang batsamaisi ba limela ba sa robala bosiu: 70% ea all ready mix plant metsi a litšila likotlo tsa ho se latele li amahanngoa ka kotloloho le lekoeba le sa laoleheng. Ha se pH. Eseng tse tiileng. Foam. Sesepa seo, bohlasoa bo benyang ka tankeng ea hau ea polokelo ha se ntho e senyang mahlo feela; ke senokoane se mafolofolo. E sitisa li-flocculants, maraba a tiileng, mme e baka kotsi ya thibelo. Basebelisi ba bangata ba tšoara foam joalo ka bothata ba litlolo. Bona iphapanyetsa ho fihlela mohlahlobi a hlaha kapa pompo e kokobela. Eo ke phoso e kgolo. Ena ke tokiso ea hau. Ha ho fluff. Ke mekhoa feela ea ho bolaea foam bakeng sa molemo.

1. Se ke oa Sebelisa Dish Soap Logic: Hobaneng ha Silicone e Betsa Maqheka a Kichineng

Ke e utlwa ka dinako tsohle: “Re mpa re fafatsa diesel e nyane ho eona.” Ema. Dizeli ke kotsi ea mollo le molato oa tikoloho. U hloka a defoaming agent bakeng sa ho hloekisa metsi a litšila limela tse itokiselitseng ho kopanya e etselitsoe sopho ena e khethehileng ea lik'hemik'hale. Metsi a litšila a na le li-hydrate tsa samente, li-surfactants tse tsoang ho hlatsoa literaka, le li-aggregates tse ntle. Sena ha se sinki ea kichineng.

Mefuta e Mebeli ea Boima ba Boima:

• E Thehiloe ka Silicone: Tsena ke li-snipers. Lerotholi le le leng le ka bolaea foam ka tankeng ea lilithara tse 1 000 hang-hang. Li na le mocheso o tsitsitseng 'me li sebetsa ho pholletsa le mefuta e phahameng ea pH (11-13). The downside? Ba siea filimi. Haeba metsi a hau a sebelisitsoeng hape ke a batching ka nepo, filimi eo e ka baka likheo holim'a konkreite. Li sebelise ha u tšoara litanka pele li tsoa, eseng ka metsing a hlamang.
• E seng Silicone (Li-polyglycols & Lioli): Tsena ke litiiso tsa tikoloho. Li senyeha ka potlako 'me li ke ke tsa baka mathata a holim'a metsi. Ha ba na mabifi haholo ho pH e phahameng. Haeba u ntse u loana le beisine e phophomang ea anoxic kapa tanka ea aeration, sena ke khetho ea hau. Ba hloka litekanyetso tse phahameng empa liphetho tse hloekileng.

Basebelisi ba bangata ba tlaleha Reddit: “Fetohile ho tloha silicone ho polyglycol feela ho fetisa oli ea lehae & tekanyo ea ho ntša mafura. E ile ea sebetsa, empa re ile ra tlameha ho eketsa lethal dose hararo.”

2. Sefi sa Dosing: Hobaneng ha ho se betere ho feta

Ho noa ho feta tekano a defoaming agent bakeng sa ho hloekisa metsi a litšila limela tse itokiselitseng ho kopanya e baka bothata bo bocha: Ho phophoma hape. U tšela silicone ka galone. Lefulo le nyamela. Joale 30 metsotso hamorao, e kgutla e tenya, greasier, le thata ho senya. Sena se bitsoa the “Phello ea Filimi ea Oli.” Defoamer e feteletseng e lutse holim'a bokahodimo, ho thibela phetiso ea oksijene le ho ts'oara lintho tse tiileng tse ngata. Ebe o eketsa defoamer e eketsehileng, ho bopa e mpe, potoloho e turang.

Mohato-ka-Mohato oa Dosing Protocol:

1. Mohato 1: Jar Lekola Metsi a Hao a Litšila. Nka 500ml sampole ka nkho e hlakileng. E tsokotse. Nako e telele hakae foam e phehella. Ena ke motheo oa hau.
2. Mohato 2: Theko ea Micro Dose. Ho sebelisa seringe, eketsa 50 li-microliters tsa defoamer eo u e khethileng. Hlohlora hape. Haeba foam e putlama ka hare 10 metsotsoana, tekanyo ea hau e nepahetse bakeng sa sehlopha seo.
3. Mohato 3: Eketsa Holimo. Sebelisa karo-karolelano ena ho bophahamo ba tanka ea hau. Li-defoam li matla. A tloaelehileng karo-karolelano ke 10-50 ppm (likarolo ka milione). Ke hoo e batlang e le 1 ho 5 li-ounces ka 1,000 lilithara. Qala tlase.
4. Mohato 4: Tlhahlobo ea Pono. 15 metsotso ka mor'a ente. Haeba u bona khanya ea mookoli (mafura a oli), u sebelisa overdose. Khaola lethal dose ka 30%.

3. Ntlha ea Ente: U se ke Ua E Lahlela Feela

Moo u eketsang defoaming agent bakeng sa ho hloekisa metsi a litšila limela tse itokiselitseng ho kopanya ke 80% tsa ntoa. Ho e lahlela ka holim'a tanka ea lilithara tse 50 000 ke tšenyo ea chelete. U phekola bokaholimo, empa foam e ntse e hlahisoa ka tlase.

Lintlha tsa Ente tse reriloeng (Khetha e Molemohali bakeng sa Setupo sa Hao):

• Ho Pump Suction: Ena ke eona e sebetsang ka ho fetisisa. Enta defoamer moleng o monyang oa pompo ea phetisetso. Mochine oa ho kuta oa pompo o o kopanya hang-hang, ho hlasela foam boemong ba molek'hule pele e etsa kobo ea bubble.
• Sephepelong sa Clarifier: Haeba foam ea hau e le ho clarifier (tanka ea ho lokisa), enta hona moo metsi a kenang teng. Sena se thibela foam ho etsa kepisi holim'a kobo ea seretse.
• Sebakeng sa Aeration Basin: Haeba u na le phekolo ea likokoana-hloko (aeration), enta defoamer butle ka ho sebelisa pompo ea peristaltic hodimo. Li-bubble tsa moea ke mohloli oa foam. Ba bolaye ha ba tswalwa.

Ke bone limela li fetoha ho tloha ho li-batch dumping ho ea ho ente ea inline le ho fokotsa tšebeliso ea tsona ea lik'hemik'hale ka 60%.

4. Tlhahlobo ea Tšebelisano: Na Lik'hemik'hale Tsa Hao Li Tla Loana?

Ua eketsa defoaming agent bakeng sa ho hloekisa metsi a litšila limela tse itokiselitseng ho kopanya ka lebenkeleng la lik'hemik'hale tse ling: li-coagulants (joalo ka alum kapa ferric chloride) le li-flocculants (li-polymer tsa anionic). Malapa ana a mabeli a na le phehisano khahlanong le e mong.

Li-polymer tsa anionic li hloile oli ea silicone. Haeba o kopanya silicone defoamer le tharollo ea hau ea polymer, defoamer e ka senya flocculant. Sekhahla sa hau sa ho lokisa lintho tse tiileng se tla phahama. Metsi a hao a tla lula a le litšila. Sekoere.

Molao oa Monoana:

• Haeba u sebelisa li-anionic flocculants (phofo e tshweu), sebelisa a defoamer e seng silicone.
• Haeba u sebelisa li-coagulants tsa cationic, silicone hangata e bolokehile, empa e leke ka nkhong pele.
• Kamehla eketsa defoamer MORA coagulant le flocculant li tsoakane. Ho e eketsa pele ho thibela ho thehoa ha floc ka ho feletseng.

Motsamaisi e mong oa polante o ile a mpolella: “Bokhopo ba rona bo ile ba feta marulelong. Re ile ra beha molato oa defoamer. Hoa fumaneha hore re e kentse pele ho polymer. Lokisa tatelano, lokisa metsi.”

5. Tlhahlobo ea Metsi: Kamoo Defoamer e Bolokang Chelete (Eseng Hlooho Feela)

Mona ke 'nete ea moruo. Metsi a theko e boima semeleng se se se loketse ho kopanya. Ua e lefella ha e kena 'me u lefa ho tsoa ka teraka. Foam ke tšitiso e thibelang ho sebelisoa hape ka potlako. Tanka e koetsoeng ke foam e nka 3x nako e teletsana ho senyeha. U lahleheloa ke nako ea tlhahiso.

Litšenyehelo-Molemo oa ho Defoaming e nepahetseng:

• Nako ea ho phomola e fokotsehile: Ha ua tlameha ho ema 4 lihora tse ngata hore lefulo le kokobele ho tsamaisa tlhakisetso. U ka potoloha metsi a hau hora e 'ngoe le e' ngoe.
• Ho Hloekisa Tanka: Foam e tšoara lintho tse tiileng holim'a metsi. Lera leo la foam le tiea ho ba lekhapetla. Ho hloekisa bokaholimo boo ho bitsa litšenyehelo $500-$2,000 mosebetsing ka tanka. Ha ho foam = ha ho lekhalo.
• Litšenyehelo tsa ho lahla: Haeba foam ea hau e jara likotlo holim'a moqomo ho ea ho e khaphatsehang, boleng ba hau ba metsi bo hlephileng. U tlameha ho hula metsi ao setsing sa phekolo ka $0.10/gallon. A $50 drum ea defoamer e ka u pholosa $5,000 litefisong tsa ho hula. Etsa lipalo.

6. Tumellano ea Taolo: Teko ea Metsotso e 10

Bolaoli ba tikoloho ea heno (EPA, Setsi sa Tikoloho, kapa e lekanang le sebaka) e tsotella lintho tse tharo mabapi le defoaming agent bakeng sa ho hloekisa metsi a litšila limela tse itokiselitseng ho kopanya:

• Oli & Tlotsa: Li-silicone defoamers ka botekgeniki ke oli. Haeba tumello ea hau ea ho tsoa e fokotsa oli & tlotsa ho 15 mg/L, silicone defoamer e tla u sutumelletsa ho feta moeli. Sebelisa "non-silicone defoamer" haeba u tsoa ka holim'a metsi.
• pH: Li-defoams ha li fetole pH, empa foam eo ba e bolaeang e ka tšoasa CO2. Haeba o tlosa lefome ka potlako beisine ea anoxic, u ka bona pH spike. E behe leihlo.
• Tse tiileng (TSS): Ha e le hantle, defoamer e ntle e tla tlase TSS ea hau ka ho lumella lintho tse tiileng ho lula ka bolokolohi.

Litokomane ke Senotlolo: Boloka maqephe a hau a MSDS le lintlha tsa litekanyetso. Ha mohlahlobi a botsa, “U sebelisa lik'hemik'hale life?” o ba neha kota. E bontsha hore o taolong. E haha ​​tšepo. E thibela lichelete hole.

7. Your Next Move: Teko ea lihora tse 48

Khaotsa ho nahana. Teko.

Mosebetsi oa hau ke ona. U na le 48 lihora. Nka mohlala ho tanka ea hau e mpe ka ho fetesisa e phophomang. Letsetsa morekisi oa lehae oa lik'hemik'hale ea fanang ka defoaming agent bakeng sa ho hloekisa metsi a litšila limela tse itokiselitseng ho kopanya. Kopa quart ea silicone le quart ea non-silicone. Etsa tlhahlobo ea nkho eo ke e hlalositseng. Etsa tlhahlobo ea litekanyetso.

Ke batla hore u fumane bonyane tekanyo e bolaeang lekoeba ka tlase 10 metsotsoana e se nang sheen e setseng.

U na le protocol. Joale phetha.
