1,Ethylene oxide kev lag luam: tus nqi ruaj khov, khoom siv-thov qauv zoo tuned
Tsis muaj zog stability nyob rau hauv raw khoom nqi: Tus nqi ntawm ethylene oxide tseem ruaj khov. Los ntawm qhov kev xav ntawm tus nqi, cov khoom lag luam ethylene raw khoom tau pom tias muaj kev ua haujlwm tsis muaj zog, thiab muaj kev txhawb nqa tsis txaus rau tus nqi ntawm ethylene oxide. Qhov tsis muaj zog ruaj khov ntawm cov nqi ethylene ncaj qha cuam tshuam rau tus nqi qauv ntawm ethylene oxide.
Tightening ntawm cov khoom noj khoom haus: Nyob rau sab muab khoom, Yangzi Petrochemical qhov kev kaw tseg rau kev saib xyuas tau ua rau muaj kev nruj ntawm cov khoom hauv cheeb tsam East Tuam Tshoj, ua rau muaj kev thauj khoom ceev ceev. Nyob rau tib lub sijhawm, Jilin Petrochemical tau nce nws cov khoom thauj, tab sis cov dej ntws qis tau txais kev sib dhos yog maj mam nce, thiab tag nrho cov khoom tseem tab tom qhia txog kev poob qis.
Kev thov qis qis me ntsis: Ntawm qhov kev thov sab, lub ntsiab downstream polycarboxylate superplasticizer monomer kev khiav hauj lwm load tau txo, thiab qhov kev thov kev txhawb nqa rau ethylene oxide tau loosened vim lub sij hawm luv luv kev hloov kho ntawm East China raw khoom thiab monomer units.
2,Palm roj thiab nruab nrab carbon cawv lag luam: tus nqi nce, tus nqi tsav tsheb tseem ceeb
Palm roj chaw tus nqi nce: Lub lim tiam dhau los, qhov chaw tus nqi ntawm cov roj xibtes tau nce siab, ua rau tus nqi siab rau cov khoom lag luam cuam tshuam.
Tus nqi ntawm cov pa roj carbon monoxide nruab nrab yog tsav los ntawm cov khoom siv raw: tus nqi ntawm cov pa roj carbon monoxide nruab nrab tau nce ntxiv, feem ntau yog vim qhov nce ntawm tus nqi ntawm cov khoom siv raw cov txiv ntoo roj. Yog li ntawd, tus nqi ntawm cov rog rog tau raug tsav, thiab cov neeg tsim khoom tau tsa lawv cov kev muab rau ib qho tom qab.
Kev ua lag luam siab carbon cawv tsis muaj zog: tus nqi ntawm cov pa roj carbon ntau hauv kev ua lag luam tau ruaj khov. Txawm hais tias muaj kev nce ntxiv hauv cov nqi ntawm cov khoom siv raw xws li cov roj xibtes thiab cov roj txiv ntoo, cov khoom lag luam muaj kev txwv, thiab cov neeg tsim khoom hauv qab tau nce lawv cov kev txaus siab rau kev nug. Txawm li cas los xij, qhov kev hloov pauv tiag tiag tseem tsis txaus, thiab kev lag luam khoom muag thiab kev xav tau nyob rau hauv qhov tsis txaus ntseeg.
3,Kev lag luam uas tsis yog ionic surfactant: tus nqi nce, tso tawm ntawm kev thov rau cov khoom siv tshuaj niaj hnub
Tus nqi nce: Kev ua lag luam uas tsis yog-ionic surfactant tau nce lub lim tiam dhau los, feem ntau yog vim qhov nce ntxiv ntawm cov nqi ntawm cov roj ntsha roj. Txawm hais tias tus nqi ntawm ethylene oxide tseem nyob ruaj khov, qhov nce ntawm cov rog rog tau ua rau tag nrho cov lag luam nce siab.
Cov khoom ruaj khov: Raws li cov khoom siv, lub Hoobkas feem ntau xa cov xaj thaum ntxov, thiab cov khoom siv tag nrho yog qhov ruaj khov.
Downstream thov ceev faj: Ntawm qhov kev thov sab, nrog rau kev nce qib ntawm "ob chav kaum", qee qhov kev txiav txim hauv cov khoom siv tshuaj lom neeg niaj hnub tau raug tso tawm ib tom qab, tab sis cov khoom siv qis qis tseem ceev faj thiab feem ntau ua haujlwm vim qhov cuam tshuam ntawm cov nqi siab.
4,Anionic surfactant kev ua lag luam: nce nqi, nruj khoom nyob rau hauv South Tuam Tshoj
Kev them nyiaj yug: Lub ntsiab tsav tsheb tom qab tus nqi nce ntawm anionic surfactants los ntawm kev nce hauv cov khoom siv roj fatty cawv. Kev nce ntxiv ntawm tus nqi ntawm cov cawv muaj roj txuas ntxiv txhawb nqa AES lub khw muag khoom.
Kev nce nqi siab ntawm cov chaw tsim khoom: Ntawm cov khoom siv sab nraud, lub Hoobkas muab cov khoom lag luam ruaj khov, tab sis vim yog cov nqi siab ntawm cov roj cawv, lub Hoobkas nqi siab tau nce. Kev xa khoom ntawm AES hauv South China cheeb tsam yog nruj me ntsis.
Kev thov qis qis maj mam tso tawm: Ntawm qhov kev thov sab, raws li "Ob chav kaum ib" kev ua yeeb yam khoom noj khoom haus tau ze, qhov kev thov qis qis tau maj mam tso tawm, tab sis cov ntawv xaj tshiab tau kos npe rau lub lim tiam no raug txwv thiab feem ntau yog me me.
5,Polycarboxylate dej txo tus neeg sawv cev monomer kev ua lag luam: Kev lag luam muaj zog, txo cov khoom siv raw khoom
Kev txhawb nqa tus nqi: Kev ua lag luam rau polycarboxylate superplasticizer monomers kuj muaj zog lub lim tiam dhau los. Ntawm tus nqi, vim lub sijhawm luv luv ntawm Satellite Petrochemical thiab Yangtze Petrochemical, cov khoom ntawm ethylene oxide hauv cheeb tsam tau txo qis, txhawb nqa tus nqi ntawm ib tus neeg.
Kev tsis txaus ntawm cov chaw muab kev pab: Hais txog kev muab khoom, qee qhov chaw nyob rau sab hnub tuaj Tuam Tshoj tau txais kev saib xyuas, thiab cov chaw muab kev pabcuam tau nruj heev. Vim muaj qhov tsis txaus ntawm cov khoom siv raw, qee lub tuam txhab tau txo lawv cov kev ua haujlwm ntawm tus kheej.
Downstream xav tos-thiab-saib: Ntawm qhov kev thov sab, vim muaj kev cuam tshuam ntawm huab cua txias, qhov nrawm ntawm kev tsim kho lub davhlau ya nyob twg tau qeeb los ntawm sab qaum teb mus rau sab qab teb. Downstream nruj kev thov tau dhau los ua qhov tseem ceeb, thiab kev ua lag luam tab tom tos rau kev thov tso tawm ntxiv.
Kev ua tau zoo ntawm ntau yam sub sectors hauv kev lag luam tshuaj sib txawv, tab sis feem ntau cuam tshuam los ntawm kev hloov pauv ntawm cov khoom siv raw, kev hloov pauv hauv cov khoom siv thiab kev xav tau, thiab cov khoom raws caij nyoog.
