Lignin ndeyechipiri kune cellulose munzvimbo dzinochengeterwa, uye inogadzirwa patsva pamwero we50 bhiriyoni matani gore rega rega. Indasitiri yepulp uye mapepa inoparadzanisa matani emamiriyoni e140 e cellulose kubva muzvirimwa gore rega rega, uye inowana anenge 50 miriyoni matani e-lignin-zvigadzirwa, asi kusvika zvino, inopfuura 95% ye lignin ichiri kubudiswa zvakananga munzizi kana nzizi se " doro dema”. Mushure mekuiswa mukati, inopiswa uye haiwanzoshandiswa zvinobudirira. Kuwedzera kuderera kwefossil simba, matura akawanda e lignin, uye kukurumidza kukura kwe lignin sainzi kunotaridza kusimukira kwakasimba kwemabhenefiti ehupfumi e lignin.

Mutengo we lignin wakadzikira, uye lignin nezvinobvamo zvine mabasa akasiyana siyana, anogona kushandiswa seanoparadzira, adsorbents/desorbers, petroleum recovery aids, uye asphalt emulsifiers. Mupiro wakakoshesesa we lignin mukusimudzirwa kwevanhu unogara muIpa yakagadzikana uye inoenderera sosi yeorganic matter, uye tarisiro yekushandiswa kwayo yakakura kwazvo. Dzidza hukama huri pakati pe lignin zvivakwa uye chimiro, uye shandisa lignin kugadzira anoshatisa uye anogona kuvandudzwa mapolima. Iyo physicochemical properties, kugadzirisa zvivakwa uye tekinoroji ye lignin zvave zvipingamupinyi kutsvagiridzo yazvino ye lignin.

Lignin sulfonate inogadzirwa kubva kune sulfite huni pulp lignin mbishi zvinhu kuburikidza nekufungisisa, kutsiva, oxidation, kusefa uye kuomesa. Chromium lignosulfonate haina kungoita mhedzisiro yekudzikisa kurasikirwa kwemvura, asiwo ine diluting mhedzisiro. Panguva imwecheteyo, iyo inewo maitiro ekudzivirira munyu, kupisa kwakanyanya uye kuenderana kwakanaka. Iri diluent ine simba rakasimba remunyu, calcium resistance uye tembiricha yekudzivirira. Zvigadzirwa izvi zvinoshandiswa zvakanyanya mumvura yakachena, mvura yegungwa, uye yakazara saturated samende simende slurries, akasiyana-siyana calcium-yakagadziriswa madhaka uye ekupedzisira-yakadzika tsime madhaka, ayo anogona kunyatso kudzikamisa madziro etsime uye kuderedza viscosity uye kugera kwedhaka.

Zviratidzo zvemuviri uye zvemakemikari zve lignosulfonate:

1. Kuita kunoramba kusingachinji pa150 ~ 160 ℃ kwemaawa gumi nematanhatu;

2. Kuita kwe2% munyu simenti slurry iri nani pane iyo iron-chromium lignosulfonate;

3. Iine simba rinopesana ne electrolyte uye inokodzera marudzi ose ematope.

Ichi chigadzirwa chakaiswa mubhegi rakarukwa rakamisikidzwa nebhegi repurasitiki, rine huremu hwekutakura hunosvika 25 kg, uye bhegi rekurongedza rakanyorwa nezita rechigadzirwa, trademark, uremu hwechigadzirwa, mugadziri uye mamwe mazwi. Zvigadzirwa zvinofanirwa kuchengetwa mudura kudzivirira hunyoro.
