Lignin bụ nke abụọ na cellulose na ihe nchekwa eke, a na-emegharị ya na ọnụego ijeri tọn 50 kwa afọ.Ụlọ ọrụ pulp na akwụkwọ na-ekewa ihe dị ka nde tọn 140 nke cellulose na osisi kwa afọ, ma na-enweta ihe dị ka nde tọn 50 nke ngwaahịa lignin, mana ka ọ dị ugbu a, ihe karịrị 95% nke lignin ka na-ahapụ ozugbo na osimiri ma ọ bụ osimiri dịka " mmanya oji”.Mgbe etinyechara ya, a na-agba ya ọkụ, ọ naghị adịkarịkwa eji ya eme ihe nke ọma.Mbelata nke ike fossil na-abawanye, ụbara nke lignin, na mmepe ngwa ngwa nke sayensị lignin na-ekpebi mmepe na-adigide nke uru akụ na ụba nke lignin.

Ọnụ ego nke lignin dị ala, na lignin na ihe ndị na-emepụta ya nwere ọrụ dị iche iche, nke a pụrụ iji mee ihe dị ka ndị na-ekesa, adsorbents / desorbers, enyemaka mgbake mmanụ, na asphalt emulsifiers.Ihe kacha mkpa lignin na-enye maka mmepe na-adigide mmadụ dabere na Inye isi iyi siri ike ma na-aga n'ihu nke ihe ndị dị ndụ, na atụmanya itinye ya dị nnọọ ukwuu.Mụta mmekọrịta dị n'etiti akụrụngwa lignin na nhazi, wee jiri lignin mee ka polymer mebie na mmeghari ohuru.Njirimara physicochemical, ihe nhazi na teknụzụ nke lignin aghọwo ihe mgbochi na nyocha nke ugbu a na lignin.

A na-eme Lignin sulfonate site na osisi sulfite pulp lignin akụrụngwa site na itinye uche, nnọchi, oxidation, filtration na ihicha.Chromium lignosulfonate abụghị naanị nwere mmetụta nke ibelata mfu mmiri, kamakwa ọ nwere mmetụta diluting.N'otu oge ahụ, ọ nwekwara njirimara nke nguzogide nnu, elu okpomọkụ na-eguzogide na ezigbo ndakọrịta.Ọ bụ ihe na-edozi ahụ nke nwere nguzogide nnu siri ike, nguzogide calcium na nguzogide okpomọkụ.A na-eji ngwaahịa ndị a eme ihe n'ọtụtụ ebe na mmiri ọhụrụ, mmiri mmiri, na nnu simenti slurries, dị iche iche nke calcium na-emeso apịtị na ultra-miri miri emi, nke nwere ike ịkwado mgbidi olulu mmiri nke ọma ma belata viscosity na ịkwa apịtị.

Ngosipụta anụ ahụ na kemịkalụ nke lignosulfonate:

1. The arụmọrụ na-anọgide na-agbanweghi agbanwe na 150 ~ 160 ℃ maka 16 awa;

2. Ọrụ nke 2% nnu ciment slurry dị mma karịa nke ígwè-chromium lignosulfonate;

3. O nwere ikike mgbochi electrolyte siri ike ma dabara maka ụdị apịtị niile.

A na-etinye ngwaahịa a n'ime akpa a kpara akpa nke ejiri akpa rọba mee ihe, na-ebu ibu nke 25 kg, na akpa nkwakọ ngwaahịa na-eji aha ngwaahịa, ụghalaahịa, arọ ngwaahịa, mmepụta ihe na okwu ndị ọzọ.Ekwesịrị ịchekwa ngwaahịa na ụlọ nkwakọba ihe iji gbochie mmiri mmiri.
