Dispersantyog ib qho surfactant nrog ob yam khoom sib txawv, lipophilic thiab hydrophilic hauv cov molecule. Nws tuaj yeem siv los ua kom tsis sib haum xeeb ntawm cov khoom tsis muaj zog thiab cov khoom organic uas nyuaj rau yaj hauv cov kua. Nws kuj tseem siv tau los tiv thaiv cov sedimentation thiab agglomeration ntawm cov khoom siv los tsim kom muaj kev ncua ruaj khov.
Anionic surfactants feem ntau yog sulfonic acid-formaldehyde condensates nrog aromatic nuclei. Muaj ob hom naphthalene thiab phenol. Naphthalene-based dispersing thiab leveling agents xws lidispersing agents NNO, MF, lwm yam,
Main indicators, AsDispersant NNO:
| Projects thiab indicators | NNO |
| Dispersion zog | ≥95% |
| PH tus nqi (1% aqueous tov) | 7—9 |
| Cov ntsiab lus sulfate | ≤ 18% |
| Dej-insoluble impurity cov ntsiab lus | ≤0.05% |
Qhov txawv thiab kev sib txuas ntawm dispersant NNO thiab MF?
Dispersant NNO sodium methylene naphthalene sulfonate yog siv los ua dispersant hauv disperse dyes, vat dyes, reactive dyes, acid dyes thiab tawv dyes, nrog zoo heev sib tsoo nyhuv, solubilization thiab dispersibility; Nws kuj tseem siv tau rau hauv textile printing thiab dyeing, Wettable tshuaj tua kab yog siv los ua dispersants, dispersants rau papermaking, electroplating additives, dej-soluble xim, pigment dispersants, dej kho cov neeg ua hauj, carbon dub dispersants, thiab lwm yam Dispersant NNO yog tsuas yog siv nyob rau hauv kev lag luam. rau pad dyeing ntawm vat dye suspension, leuco acid dyeing, thiab dyeing ntawm dispersive thiab soluble vat dyes. Nws kuj tseem siv tau rau dyeing silk / wool interwoven fabrics, thiaj li tsis muaj xim ntawm cov txhob lo lo ntxhuav. Tus neeg sawv cev dispersing NNO yog tsuas yog siv nyob rau hauv kev lag luam dyeing raws li ib tug dispersion pab nyob rau hauv dispersion thiab pas dej manufacturing, roj hmab emulsion stability, thiab tawv tanning pab. Dispersant MF sodium methylene bis-methyl naphthalene sulfonate, formaldehyde condensate ntawm sodium methyl naphthalene sulfonate, yog ib qho anionic surfactant, yooj yim soluble hauv dej, yooj yim nqus noo noo, tsis-flammable, muaj zoo heev diffusivity thiab thermal stability Resistance, tsis muaj permeability thiab foaming, tsis kam mus rau acid thiab alkali, dej tawv thiab inorganic ntsev, tsis muaj affinity rau paj rwb, linen thiab lwm yam fibers; affinity rau cov protein thiab polyamide fibers; tuaj yeem siv nrog anionic thiab nonionic surfactants tib lub sijhawm, Tab sis tsis tuaj yeem tov nrog cationic dyes lossis surfactants; lub peev xwm los tiv thaiv disperse vat dye hais los ntawm tshav kub agglomeration yog zoo dua NNO. Tam sim no, cov dispersant NNO ua nyob rau hauv tsev thiab txawv teb chaws muaj tsis zoo kub dispersion kev ua tau zoo, lub teeb xim tab sis tsis kub kub tsis kam, thiab kub stability ntawm txog 80 ℃; thiab txawm hais tias qhov kub thiab txias stability ntawm dispersant MF mus txog 130 ℃ 4 rau 5, tab sis nws yog xim av hmoov thiab siv tsis tau rau disperse lub teeb xim dyes.
Lub ntsiab ntsuas ntawmDispersant MF:
| Projects thiab indicators | MF |
| Dispersion zog | ≥95% |
| PH tus nqi (1% aqueous tov) | 7—9 |
| Cov ntsiab lus sulfate | ≤ 5% |
| Thaum tshav kub kub stability 130 ° C | 4-5 |
| Dej-insoluble impurity cov ntsiab lus | ≤ 0.05% |
| Calcium thiab magnesium ion ntsiab lus ppm | ≤4000 |
