Sodium lignosulfonateari natural polima. Iyo ndeye-chigadzirwa chekugadzira pulp, inova polymer ye4-hydroxy-3-methoxybenzene. Ine simba dispersibility. Nekuda kwehuremu hwemamorekuru hwakasiyana uye mapoka anoshanda, ine madhigirii akasiyana edispersibility. Icho chinhu chepamusoro chinoshanda chinogona kushambadzwa pamusoro pezvikamu zvakasiyana-siyana zvakasimba uye chinogona kuitisa simbi ion exchange. Iyo inewo mapoka akasiyana-siyana anoshanda muchimiro chayo, saka inogona kuburitsa condensation kana hydrogen bonding nemamwe makomisheni.
Nekuda kwechimiro chayo chakakosha,sodium lignosulfonateine pamusoro physicochemical zvinhu zvakadai kupararira, emulsification, solubilization uye adsorption. Zvigadzirwa zvayo zvakagadziridzwa zvinoshandiswa semineral nutrient surfactant, uye maitiro ekugadzira anga akura.
Application musimboti wesodium lignosulfonate:
Nhamba yekabhoni maketani inosiyana zvakanyanya zvichienderana neyakasiyana zvinhu zvakatorwa kubva ku lignin. Mamwe akakodzera kugadzirwa kwefetereza uye mamwe akakodzera kuisa mishonga yezvipembenene. Iine mabasa akasiyana-siyana anoshanda, dispersibility uye chelation, izvo zviri nyore kusanganisa nesimbi zvinhu kuti zvigadzire chelate state, kuvandudza muviri uye kemikari zvinhu zvesimbi zvinovaka muviri zvinhu, kuchengetedza mari uye kuvandudza kushanda zvakanaka. Iyo adsorption uye inononoka-kuburitsa zvimiro zve lignin zvinogona kuchengetedza zvirinani kushanda kwemakemikari fetiraiza uye kuita kuti isunungurwe zvishoma nezvishoma. Chinhu chakanaka chinononoka-kuburitswa cheorganic compound fertilizer. Lignin imhando yepolycyclic macromolecular organic compound ine akawanda mapoka asina kunaka, ane hukama hwakasimba hwepamusoro-valent metal ions muvhu.
Sodium lignosulfonateinogona zvakare kushandiswa kugadzira mishonga yezvipembenene. Lignin ine nzvimbo yakakura chaiyo uye ine mapoka akasiyana-siyana anoshanda, ayo anogona kushandiswa semushonga unononoka kuburitsa mumiririri.
Pane misiyano muchimiro pakati pe lignin muzvirimwa uye lignin mushure mekuparadzana. Iyo ichangobva kugadzirwa sero madziro echirimwa cell division yakatetepa uye yakapfuma mune acidic polysaccharides senge pectin, iyo zvishoma nezvishoma inoburitsa cellulose uye hemicellulose. Iwo maseru anopatsanura kuita akasiyana akasarudzika xylem maseru (huni fibers, tracheids nemidziyo, nezvimwewo). Kana iyo S1 layer yemadziro echipiri yakaumbwa, lignin inotanga kuumba kubva kumakona emadziro ekutanga. Chiitiko ichi chinowanzonzi lignification. Nekukura kwemuti wezvirimwa, lignification inokura yakananga kune intercellular layer, madziro ekutanga uye yechipiri madziro. Lignin inoiswa zvishoma nezvishoma mukati uye pakati pemadziro emadziro, ichisunga masero nemaseru pamwechete. Munguva yekugadziriswa kwemiti yemasero emadziro, lignin inopinda mukati memadziro emadziro, ichiwedzera kuoma kwemadziro emadziro, ichikurudzira kuumbwa kwema mechanical tissues, uye kuwedzera simba remagetsi uye simba rekutakura masero emiti uye matishu; Lignin inoita sero madziro hydrophobic uye inoita kuti chirimwa masero asapindike, ichipa vimbiso yakavimbika yekufambisa kure-kure kwemvura, zvicherwa uye organic zvinhu mumuviri wechirimwa; Kupinda kwe lignin mumadziro emadziro kunoumbawo chipingamupinyi chemuviri, zvinonyatso kudzivirira kupinda kwezvirwere zvakasiyana-siyana zvezvirimwa; Iyo inodzivirira mamorekuru ekuitisa mu xylem kubva pakubuda kwemvura, uye panguva imwechete inoita kuti zvirimwa zvepanyika zvirarame munzvimbo isina kuoma, izvo zvinowedzera kurwisa chirwere chechirimwa. Lignin inobata basa mukusunga cellulose, hemicellulose uye inorganic munyu (kunyanya silicate) muzvirimwa.
Zvinhu zvinokanganisa kuora kwe lignin zvinosanganisira ivhu pH, mwando uye mamiriro ekunze. Zvimwe zvinhu, sekuwanikwa kwenitrogen uye ivhu mineralogy, zvinewo kukanganisa. Iyo adsorption yeFe neAl oxides pa lignin inogona kuderedza kuparara kwe lignin.
