Wobalalitsandi surfactant ndi zinthu ziwiri zosiyana, lipophilic ndi hydrophilic mu molekyulu. Angagwiritsidwe ntchito uniformly kumwazikana inorganic ndi organic olimba particles kuti n'zovuta kupasuka mu madzi. Angagwiritsidwenso ntchito kupewa sedimentation ndi agglomeration olimba particles kupanga khola kuyimitsidwa.
Ma anionic surfactants makamaka ndi sulfonic acid-formaldehyde condensates yokhala ndi ma nuclei onunkhira. Pali mitundu iwiri ya naphthalene ndi phenol. Naphthalene-based dispersing and leveling agents mongaobalalitsa othandizira NNO, MF, ndi zina,
Zizindikiro zazikulu zaDisperant NNO:
| Ntchito ndi zizindikiro | NNO |
| Mphamvu yomwazikana | ≥95% |
| PH mtengo (1% yankho lamadzi) | 7—9 |
| Zinthu za sulphate | ≤18% |
| Zonyansa zosasungunuka m'madzi | ≤0.05% |
Kodi pali kusiyana kotani pakati pa dispersant NNO ndi MF?
Dispersant NNO sodium methylene naphthalene sulfonate amagwiritsidwa ntchito makamaka ngati dispersant mu obalalika utoto, vat utoto, zotakasika utoto, utoto wa asidi ndi utoto wachikopa, ndi zotsatira zabwino kwambiri akupera, solubilization ndi dispersibility; itha kugwiritsidwanso ntchito mu kusindikiza nsalu ndi utoto, mankhwala Wettable ntchito ngati dispersants, dispersants kwa papermaking, electroplating zowonjezera, utoto sungunuka madzi, dispersants pigment, othandizira madzi mankhwala, mpweya wakuda dispersants, etc. Dispersant NNO makamaka ntchito makampani zopaka utoto wa vat dye kuyimitsidwa, utoto wa leuco acid, ndi utoto wa dispersive ndi utoto wosungunuka wa vat. Itha kugwiritsidwanso ntchito podaya nsalu za silika/ubweya zolukana, kuti pasakhale mtundu pa silika. Wobalalitsa NNO amagwiritsidwa ntchito makamaka pamakampani opanga utoto ngati chithandizo chobalalitsa pakubalalitsa ndi kupanga nyanja, kukhazikika kwa emulsion ya rabara, ndi chithandizo chowotcha zikopa. Dispersant MF sodium methylene bis-methyl naphthalene sulfonate, formaldehyde condensate ya sodium methyl naphthalene sulfonate, ndi anionic surfactant, sungunuka mosavuta m'madzi, mosavuta kuyamwa chinyezi, chosayaka moto, ali ndi diffusivity kwambiri ndi matenthedwe bata Kukaniza, foaming permeability, kukana asidi ndi alkali, madzi olimba ndi mchere wachilengedwe, ayi kuyanjana kwa thonje, nsalu ndi ulusi wina; kuyanjana kwa mapuloteni ndi ulusi wa polyamide; angagwiritsidwe ntchito ndi anionic ndi nonionic surfactants pa nthawi yomweyo , Koma sangathe kusakaniza utoto cationic kapena surfactants; Kuthekera koletsa kumwaza tinthu ta utoto wa vat kuchokera ku kutentha kwabwino kuposa NNO. Pakali pano, dispersant NNO opangidwa kunyumba ndi kunja ali osauka mkulu kutentha kubalalitsidwa ntchito, kuwala mtundu koma osati mkulu kutentha kukana, ndi kutentha kukana bata pafupifupi 80 ℃; ndipo ngakhale kutentha kukana bata wa dispersant MF kufika 130 ℃ 4 mpaka 5, koma Ndi ufa bulauni ndipo sangagwiritsidwe ntchito kumwazikana kuwala akuda utoto.
Zizindikiro zazikulu zaDispersant MF:
| Ntchito ndi zizindikiro | MF |
| Mphamvu yomwazikana | ≥95% |
| PH mtengo (1% yankho lamadzi) | 7—9 |
| Zinthu za sulphate | ≤5% |
| Kukhazikika kwa kutentha kwa 130 ° C | 4-5 |
| Zonyansa zosasungunuka m'madzi | ≤0.05% |
| Calcium ndi magnesium ion zili ppm | ≤4000 |
Timakhulupirira kwambiri kuti mbiri yabwino imachokera kuzinthu zodziwika ndi ogwiritsa ntchito, zodalirika komanso zokhazikika zomwe zimagwiritsidwa ntchito, komanso ntchito zachidwi. Ndife okonzeka kukulitsa limodzi ndi makasitomala athu ndi anzathu!
Disperant NNO, Dispersant MFHigh-concentration dispersant，Mungathe kupeza zitsanzo kwaulere ndi chithandizo makonda ntchito.
