Chinhu chakakosha chesodium lignosulfonateinonzi benzyl propane derivative. Iro sulfonic acid boka rinotarisa kuti rine mvura yakanaka yekunyungudika, asi haina kunyungudika mu ethanol, acetone uye mamwe organic solvents. Typical softwood lignosulfonate inogona kuratidzwa nekemikari inotevera C9H8.5O2.5 (OCH3) 0.55 (SO3H) 0.4.
Mamiriro ezvimiro uye kugoverwa kwema molecular weight ye lignosulfonate inoona kuti yakasiyana kubva kune mamwe ma-synthetic surfactants mune zvakawanda. Iine zvinotevera zvemuviri uye zvemakemikari zvimiro:
1. Iyo yepamusoro inoshanda lignosulfonate molecule ine akawanda hydrophilic mapoka uye haina linear alkyl cheni, saka kunyungudika kweoiri kwayo hakuna kusimba, hydrophilicity yayo yakasimba kwazvo, uye its hydrophobic skeleton is spherical, uye haigone kuve neatse phase interface kurongeka seyakajairwa. low molecular surfactants. Nokudaro, kunyange zvazvo ichigona kuderedza kudzvinyirirwa kwepamusoro kwemhinduro, ine zvishoma zvinodzora pamusoro pekunetseka kwepamusoro uye haizogadziri micelles.
2.The viscosity ye slurry inogona kuderedzwa nekuwedzera chiduku che lignosulfonate mu-viscous slurry kuburikidza nekushambadza uye kupararira; Kana yakawedzerwa kune yakaonda kumiswa, kukurumidza kugadzirisa kwezvikamu zvakamiswa zvinogona kuderedzwa. Izvi zvinodaro nekuti lignosulfonate ine yakasimba hydrophilicity uye electronegativity. Inoumba mapoka eanionic mune aqueous solution. Kana ichishambadzirwa pane dzakasiyana siyana organic kana inorganic particles, zvimedu zvinochengeta yakagadzikana yekupararira mamiriro nekuda kwekurambana pakati pemapoka eanionic. Zvimwe zvidzidzo zvakare zvinoratidza kuti kushambadza uye kupararira kwe lignosulfonate kunokonzerwa neiyo electrostatic repulsion force uye kudzorwa kwetububu tudiki, Kuzora kwemabhururu madiki ndicho chikonzero chikuru chekupararira kwayo: dispersion effect ye lignosulfonate inosiyana nehuremu hwayo hwemamorekuru uye kumiswa. system. Kazhinji, zvikamu zvine huremu hwemamorekuru kubva pa5000 kusvika ku40,000 zvine mhedzisiro irinani yekuparadzira.
3.chelation lignosulfonate ine mamwe phenol hydroxyl, alcohol hydroxyl, carboxyl uye carbonyl mapoka, umo iyo un shared electron pairs paatomu yeokisijeni inogona kuumba zvisungo zvekubatanidza nesimbi ions, zvichiita kuti chelation, iite metal chelates ye lignin, nokudaro iine unhu hutsva. . Semuenzaniso, chelation ye lignosulfonate ine iron ion, chromium ion, nezvimwewo inogona kushandiswa kugadzira mafuta ekuchera madhaka akaonda, uye chelation inoitawo kuti ive neimwe corrosion uye scale inhibition effects, inogona kushandiswa semumiririri wemvura.
4.Basa rekubatanidza riri mumiti yakasikwa. Sekunamira, lignin inogoverwa kumativi efiber uye pakati pemafiber maduku mukati mefiber, akaiswa nefibers uye maduku maduku, zvichiita kuti ive yakasimba skeleton structure. Chikonzero nei miti isingagone kuwira pasi kwemakumi emamita kana kunyange mazana emamita imhaka yekunamatira kwe lignin. Lignosulfonate yakaparadzaniswa nedoro dema inogona kugadziridzwa kudzoreredza simba rekunamira rekutanga, uye shuga nezvinobuda mudoro remarara zvinogona kubatsira kusimudzira simba ravo rekunamatira kuburikidza nemutual synergistic athari.
5.Foaming performance The foaming performance ye lignosulfonate yakafanana neye general polymer surfactants, iyo ine hunhu hwekushomeka kwefuro, asi kugadzikana kwakanaka kwefuro, uye kupupuma kwe lignosulfonate kuchava nekukanganisa kwayo kushanda kwayo. Semuenzaniso, kana ichishandiswa sekrete yemvura inoderedza, kune rumwe rutivi, nekuda kwekuzora kwemafuta anogadzirwa ne lignosulfonate, iyo fluidity yekrete ichawedzera uye kushanda kuchava nani; Kune rimwe divi, iyo inopupuma pfuma ichawedzera kupinza kwemhepo uye kuderedza simba rekongiri. Kana ichishandiswa semhepo inopinza mvura inoderedza mumiririri, zvinobatsira kuvandudza kusimba kwechando uye kusimba kwekongiri.
