I-Lignin yeyesibini kuphela kwi-cellulose kwiindawo zolondolozo lwendalo, kwaye ihlaziywa kwakhona ngesantya seetoni ezibhiliyoni ezingama-50 minyaka le. Ishishini le-pulp kunye nephepha lahlula malunga ne-140 yezigidi zeetoni zeselulosi kwizityalo minyaka le, kwaye lifumana malunga ne-50 yezigidi zeetoni zemveliso ye-lignin, kodwa ukuza kuthi ga ngoku, ngaphezulu kwe-95% ye-lignin isakhutshelwa ngokuthe ngqo emilanjeni okanye emilanjeni njenge " utywala obumnyama”. Emva kokuba igxininiswe, iyatshiswa kwaye ayifane isetyenziswe ngokufanelekileyo. Ukuncipha okwandayo kwamandla efosili, ubutyebi obuninzi be-lignin, kunye nophuhliso olukhawulezayo lwenzululwazi ye-lignin lumisela uphuhliso oluzinzileyo lweenzuzo zoqoqosho ze-lignin.

Iindleko ze-lignin ziphantsi, kwaye i-lignin kunye ne-derivatives yayo inemisebenzi eyahlukeneyo, enokusetyenziswa njenge-dispersants, i-adsorbents / desorbers, i-petroleum recovery aids, kunye ne-asphalt emulsifiers. Igalelo elibaluleke kakhulu le-lignin kuphuhliso oluzinzileyo lomntu lukukubonelela ngomthombo ozinzileyo noqhubekayo wezinto eziphilayo, kunye nethemba lokusetyenziswa kwayo kubanzi kakhulu. Funda ngobudlelwane phakathi kweepropathi ze-lignin kunye nolwakhiwo, kwaye usebenzise i-lignin ukwenza iipholima ezinokonakala nezinokuhlaziywa. Iimpawu ze-physicochemical, iipropathi zokucubungula kunye neteknoloji ye-lignin ziye zaba yimiqobo kuphando lwangoku kwi-lignin.

I-Lignin sulfonate yenziwe kwi-sulfite wood pulp lignin ekrwada ngokuxinzelela, ukutshintshwa, i-oxidation, ukuhluzwa kunye nokomisa. I-Chromium lignosulfonate ayinayo kuphela umphumo wokunciphisa ukulahleka kwamanzi, kodwa ibuye ibe nefuthe lokuhlambulula. Ngelo xesha, nayo ineempawu zokumelana netyuwa, ukumelana nokushisa okuphezulu kunye nokuhambelana kakuhle. I-diluent enokumelana netyuwa eqinile, ukuxhathisa kwe-calcium kunye nokumelana nobushushu. Iimveliso zisetyenziswa kakhulu kumanzi acocekileyo, amanzi olwandle, kunye nodaka lwesamente enetyuwa egcweleyo, udaka olwahlukeneyo oluphathwe nge-calcium kunye nodaka olunzulu kakhulu, olunokuthi luzinzise ngokufanelekileyo udonga lomthombo kunye nokunciphisa i-viscosity kunye nokuchetywa kodaka.

Iimpawu zomzimba kunye neekhemikhali ze-lignosulfonate:

1. Umsebenzi uhlala ungatshintshanga ku-150 ~ 160℃ iiyure eziyi-16;

2. Ukusebenza kwe-2% yetyuwa ye-samente slurry ingcono kune-iron-chromium lignosulfonate;

3. Inamandla okulwa ne-electrolyte kwaye ifanelekile kuzo zonke iintlobo zodaka.

Le mveliso ifakwe kwisikhwama esilukiweyo esifakwe kwisikhwama seplastiki, esinesisindo sokupakisha se-25 kg, kwaye isikhwama sokupakisha siphawulwe ngegama lemveliso, uphawu lokuthengisa, ubunzima bemveliso, umenzi kunye namanye amagama. Iimveliso kufuneka zigcinwe kwindawo yokugcina impahla ukukhusela ukufuma.
