Los ntawm textiles mus rau petrochemicals, kev siv zoo kawg nkaus ntawm silicone defoamers hauv rau lub lag luam loj

Hauv kev lag luam textile printing thiab dyeing, daim ntawv thov ntawm silicone defoamers yog qhov tseem ceeb.

Sizing txheej txheem: Dej-emulsion silicone defoamers (xws li silicone polyether) tau ntxiv rau hauv lub tank sizing ntawm tus nqi ntawm 0.2-0.25 g / L kom tiv thaiv kev ua npuas ncauj zoo.

Chemical Fiber Oils: Ntxiv 0.02-0.04% dej-emulsion defoamers rau cov tshuaj fiber ntau cov roj formulation, thiab xyuas kom cov roj muaj silicone roj, txhim khu cov nyhuv defoaming.

Desizing thiab Refining: Polyether-muaj silicone defoamers raug xaiv rau defoaming xav tau thaum lub sij hawm desizing thiab refining txheej txheem.

Bleaching thiab Dyeing: Muaj zog acidic silicone defoamers yuav tsum tau ua thaum bleaching; rau dyeing, polyether silicone yog nyiam rau tshuaj tsuag dyeing vim nws siab -kub defoaming thiab qis- kub dej solubility zog, thiab nws tsis stains ntaub.

Hauv kev lag luam petrochemical, silicone defoamers tau dav siv.

Drilling thiab Roj Ntau Lawm: Ethyl silicone roj los yog methyl silicone roj emulsions yog siv los ua av nkos additives rau defoam thaum lub sij hawm drilling. Hauv kev tsim cov roj, defoaming rods nrog cov ntsiab lus melting siab tshaj qhov kub ntawm lub taub hau ua npuas ncauj yog siv, thiab defoamers ntawm concentrations ntawm 0.025-0.0065 mg / kg yog ntxiv rau cov roj crude los txhim kho lub peev xwm ntau lawm.

Natural Gas Processing: A 2% tov ntawm dimethyl silicone roj yog siv rau kev nqus roj; ntxiv qhov tsim nyog tus nqi ntawm defoamer thaum lub sij hawm roj - roj sib cais demulsification tuaj yeem ua tiav demulsification thiab defoaming teebmeem.

Kev kho kom zoo thiab siab -Lub Zog Hluav Taws Xob: Ntxiv cov defoamers thaum lub tshuab nqus tsev distillation tuaj yeem txhim kho cov xim feem ntau thiab nthuav dav cov feem ntau. Cyanoalkyl polysiloxanes tau ntxiv ua cov defoamers muaj txiaj ntsig zoo rau siab - roj hluav taws xob.

Asphalt thiab Residue Roj: Ntxiv cov roj silicone hauv thaj tsam ntawm 0.2 × 10⁻⁶ txog 2.0 × 10⁻⁶ pab nrog defoaming.

Drilling Fluids thiab Lubricating Roj: Ntxiv siloxane rau siab -viscosity sulfonium hlau ntsev drilling kua tuaj yeem txhim kho cov nyhuv defoaming. Ntxiv cov roj silicone rau cov roj lubricating muaj txiaj ntsig zoo hauv kev defoaming vim nws tsis zoo solubility thiab tsis tshua muaj qhov nro.

Hauv kev lag luam ntawv, daim ntawv thov ntawm silicone defoamers yog feem ntau xav txog hauv qab no:

Pulping: Siv silicone emulsion defoamers ntawm qhov sib ntxiv ntawm 90g / T ntawm daim ntawv zoo tiv thaiv cov teeb meem foaming thaum lub sij hawm pulping.

Coated Paper: Tsis yog -silicone defoamers feem ntau yog siv thaum lub sij hawm txheej txheej ntawm cov ntawv coated.

Kev kho dej khib nyiab: Dej-raws li silicone defoamers ua lub luag haujlwm tseem ceeb hauv kev kho dej khib nyiab hauv kev ua ntawv.

Cov txheej txheem ntau lawm ntawm coatings thiab inks tso siab xav tau ntawm defoamers.

Dej-raws li Txheej: Cov tshuaj uas tsis zoo hauv dej yog siv los ua defoamers, xws li cov roj ntxhia, dej cawv ntau dua, thiab silicone resins. Ntawm cov no, silicone yog qhov zoo tshaj plaws defoamer rau dej -raws li txheej.

Tsis yog - dej- Raws li Cov Txheej Txheem: Cov tshuaj uas tsis zoo soluble hauv cov kuab tshuaj organic feem ntau yog siv, xws li qis cawv thiab silicone resins (siv raws li qhov tsim nyog).

Pom zoo silicone defoamers: Ntau hom silicone defoamers raug pom zoo nyob ntawm hom txheej, xws li roj silicone, hydrophobic SiO2 sib tov, thiab sib tov ntawm polyether polysiloxane thiab hydrophobic SiO2.

Kev thov ntawm silicone defoamers yog qhov tseem ceeb hauv kev lag luam tshuaj ntxuav tes.

Powdered detergents: Polysiloxanes thiab hloov kho sodium tripolyphosphate yog siv los ua cov khoom siv ntxiv los txhim kho kev ua haujlwm ntawm cov detergents.

Cov tshuaj ntxuav hlau: Defoamers yuav tsum ua kom alkali- tiv taus, pob tshab, thiab muaj kev ua haujlwm defoaming.

Kev siv silicone defoamers hauv kev lag luam khoom noj yuav tsum tau tswj nruj heev.

Khoom noj khoom haus-qib defoamers: Khoom noj khoom haus- qib polysiloxane resins nrog dimethyl polysiloxane ua cov khoom tseem ceeb thiab muaj tsawg dua 15% SiO2 tuaj yeem siv rau defoaming aqueous solutions thiab roj-raws li cov khoom.
