ndi anionic Surfactant . Ndi anachita mankhwala nkhuni zamkati ndi sulfure dichloride amadzimadzi njira ndi sulfite. Ndi chochokera kwa ulimi wa zamkati. Ambirife 4-hydroxy-3-methoxy benzene. Polima. Chifukwa mitundu yosiyanasiyana ya mitengo ndi kusiyana zochita sulfonation, kulemera maselo a lignosulfonate ranges 200 10,000, ndipo dongosolo mankhwala silinakwaniritsidwe zotsimikizika. Ambiri, otsika maselo kulemera nkhuni sulfonates, makamaka liniya, tili limodzi mu njira; macromolecular sulfonates lignin ali makamaka nthambi, naonetsere khalidwe polyelectrolytic pa TV amadzimadzi. The yosakongola lignin sulfonate ntchito wambirimbiri mu pelletization chakudya nyama, ndi woyengedwa lignin sulfonate ntchito monga dispersant mafuta pobowola matope; ndi miyala flotation wothandizira, ndi dispersant kwa amatope, dyestuff, ndi mankhwala; chifukwa zitsulo Makamaka, chitsulo, mkuwa, ndi ayoni stannous ndi luso labwino chelating ndi ogwira chelating wothandizira.
Pali awiri mitundu onse:
1) The lignosulfonate kashiamu pansi pa kuwombola ion;
2) Panthawi imeneyi pulping, sodium carbonate kapena hydroxide ndi sodium ntchito m'malo okusayidi kashiamu kapena hydroxide calcium. Njira n'chosoŵa chifukwa mtengo wa carbonate ndi sodium kapena hydroxide ndi sodium ndi zambiri kuposa za okusayidi kashiamu kapena hydroxide calcium.
Ndi zamkati mphero zinyalala ku mphero pepala, pali zambiri njira yokonza atatu.
1. sulfite kapena bisulfite ali madzi zamkati zinyalala kashiamu hydrosulfite pulping mwachindunji Chili ndi magulu hydroxyl mu lignin molekyulu kupanga lignin sulfonate. Kuwonjezera 10% mkaka wa laimu kuti mowa ndi zinyalala ndi kutentha pa (95 ± 2) ° C kwa mphindi 30. The calcification njira analola kukhazikika, precipitate anali osasankhidwa, ndipo asidi sulfuric Chinawonjezeka pambuyo kusamba. Zosefera kuchotsa kashiamu sulphate. Na2CO3 anali ndiyeno anati kwa filtrate kuti atembenuke kashiamu lignosulfonate kuti sulfonate ndi sodium. Kutentha anachita ndi makamaka 90 ° C. Pambuyo yatikhudza 2 H, izo amaloledwa kuima ndi zosafunika monga sulphate kashiamu achotsedwa ndi kusefera. Filtrate anali anaikira ndi mankhwala wotsimikiza anali utakhazikika.
2. effluent ku papermaking effluent ntchito monga zipangizo. Choyamba kuwonjezera pafupifupi 50% kuikapo maganizo asidi sulfuric kwa madzi zinyalala ndi kusonkhezera kwa 4-6 h. Ndiye ntchito mkaka wa laimu, sedimentation, kusefera, kumenyedwa, asidi kuvunda, sodium carbonate kutembenuka, ndende ndi kuyanika.
3. The waste liquid from the grass pulping process is used as raw material. Method 2

ndi sodium lignosulphonatewakagwiritsidwe:
Lignosulphonic asidi ndi sodium (nkhuni ndi sodium) ndi Tingafinye ku nsugwi ndondomeko pulping kuti wakhala anaikira, kusinthidwa ndi utsi zouma. Mankhwala ndi kuwala chikasu (bulauni) ufulu madzi ufa, sungunuka m'madzi, m'khola katundu mankhwala, ndipo si kuwola ndinso mu yaitali losindikizidwa yosungirako. Lignin angapo mankhwala ndi mtundu wa pamwamba yogwira wothandizira. Ungatithandize mankhwala ambiri mwa kusinthidwa, processing, Kuwonjezera pa vuto ndi njira zina. Ndi zimagwiritsa ntchito utomoni, labala, utoto, mankhwala, ziwiya zadothi, simenti, phula, chakudya, madzi mankhwala, madzi Malasha slurry, konkire, refractories, oilfield kuboola fetereza pawiri, yadothi, alimkuponya, zomatira. Kudzera zatsopano, izo imatsimikizirika kuti lignosulfonates zimathandiza kwambiri ku kapewedwe ka nthaka mchenga, ndipo iwo akhoza kugwiritsidwa ntchito ngati wothandizira chipululu mchenga. Zinthu zofunika ndi:
1. Konkire madzi kuchepetsa wothandizila: Ndi powdery otsika mpweya kumukopa retarding madzi kuchepetsa wothandizila ndipo ali anionic pamwamba yogwira. Iwo ali kumamatira ndi kupezeka zotsatira pa simenti ndi kusintha katundu osiyanasiyana thupi konkire. Kuchepetsa ntchito madzi ndi oposa 13%, patsogolo workability konkire, ndi kuchepetsa kutentha kwa hydration mu gawo oyambirira hydration a simenti. Iwo akhoza kukonza mu oyambirira mphamvu wothandizila, retarders, wothandizila zoletsa kuwuma, ikukoka wothandizira, etc. The kusakanizikana madzi opangidwa ndi superplasticizer ndi kwenikweni palibe precipitate.
2. Malasha Water slurry zina: Kuwonjezera mankhwala pa yokonza slurry madzi khala angathe kuonjezera linanena bungwe la mphero yapamwamba, kukhala chikhalidwe yachibadwa a dongosolo pulping, kuchepetsa mowa mphamvu ya pulping, nadzawonjezapo pa ndende ya slurry madzi malasha ndi gasification ndondomeko. , Mowa oxygen, mowa khala kuchepa Mwachangu mpweya ozizira kuchuluka, ndipo akhoza kupanga madzi slurry kuchepetsa kukhuthala ndi kukwaniritsa pamlingo winawake bata ndi fluidity.
3. zipangizo Refractory ndi ceramic thupi zolimba: Mu ndondomeko ya zotsimikizira zikuluzikulu matailosi khoma ndi njerwa refractory, ndi zosaphika particles zinthu zikhoza mwamphamvu angongole, ndi mphamvu ya akusowekapo akhoza chinawonjezeka ndi 20% 60%.
4. pongotayira ndi dispersant kwa makampani utoto ndi processing mankhwala: Pamene ntchito ngati dispersants ndi fillers kwa nsalu moŵa ndi kumwazikana utoto, izo angadwale mtundu mphamvu ya utoto, kupanga yunifolomu ankaudaya zambiri, ndi kufupikitsa nthawi utoto umapezeka; Thiabendazole angagwiritsidwe ntchito ngati filler, dispersant ndi kusakhulupirira wothandizila kusintha kwambiri mlingo kuyimitsidwa ndi wettability wa ufa wettable.
5. Monga binder kwa powdery ndi granular zipangizo: Press mipira chifukwa ufa chitsulo miyala, ufa kutsogolera-nthaka, malasha pulverized ndi coke ufa; kukanikiza ya chitsulo chosungunula ndi kuponyedwa mtundu zitsulo mchenga; njerwa khoma ndipo pansi matailosi, etc. akamaumba; Mpira wa nkhani mchere akhoza kupeza mphamvu yapamwamba, bata wabwino, ndi zotsatira zabwino za lubricating nkhungu.
6. Diluting dispersant ndi kukhuthala kuchepetsa wothandizila mu pobowola; chikusintha fluidity mu yosakongola potumiza mafuta ndi kuchepetsa mowa mphamvu. Mankhwala mafuta, amagwiritsidwanso ntchito ngati wothandizira kuyeretsa, dispersant, mkulu soda zowonjezera, dzimbiri woletsa, antistatic wothandizira, emulsifying kukhuthala reducer, dewaxing sera woletsa, ndi zina zotero.
