CovDispersing agent NNOmechanism ntawm dispersant yog ntau tus neeg muaj kev nkag siab me ntsis ntawm nws. Hauv kev tsim khoom thiab kev ua haujlwm ntawm lub sijhawm ntev, muaj ntau tus neeg uas tau sab laj txog qhov teeb meem no. Niaj hnub no, tshav ntuj thiab tshav ntuj, thiab tsis muaj dab tsi tsis ncaj ncees lawm.
● Adsorption rau ntawm qhov chaw ntawm cov khoom siv, kom lub ntsej muag ntawm cov khoom condensed yog yooj yim rau ntub.
● PolymerDispersing agent NNOtsim cov txheej txheem adsorption rau ntawm qhov chaw ntawm cov khoom siv, ua kom cov nqi ntawm cov khoom ntawm cov khoom thiab ua rau cov tshuaj tiv thaiv quab yuam ntawm cov khoom ua rau peb-dimensional obstacles.
● Ua kom cov khoom particle nto los tsim cov txheej txheem ob chav molecular, lub ncov qaumteb qabteb ntawm sab nraud dispersant thiab dej muaj ib tug muaj zog affinity, nce qib ntawm cov khoom uas ntub dej los ntawm dej. Cov khoom uas nyob deb ntawm electrostatic repulsion.
● Ua kom lub cev tsis sib xws, nce kev ncua kev kawm, tsis muaj nag lossis daus, kom tag nrho cov kab ke muaj tib lub cev thiab tshuaj lom neeg.
Dej-soluble polymer raws li ib tug dispersant yuav muaj ntau yam kev siv, dab tsi yog nws mechanism ntawm kev txiav txim, qhov no yog ib tug ntau ntawm cov neeg txaus siab rau, hnub no peb yuav ua raws li covDispersing agent NNOmanufacturers ua ke los kawm cov ncauj lus no!
Lub mechanism ntawm kev txiav txim ntawm dej-soluble polymer li dispersant yog:
(1) Lawv ntxiv rau qhov viscosity ntawm slurry, sib npaug rau nyias txheej ntawm lubrication zaj duab xis txuas rau saum npoo ntawm fiber ntau, ua lub luag haujlwm ntawm cov dej-soluble lubricant, kom cov fiber ntau zawv zawg tsis muaj entanglement;
(2) Qhov nce ntawm slurry viscosity zoo heev cuam tshuam rau kev ywj pheej ntawm fiber ntau txav hauv dej, kom cov fibers tsis sib cuag, txo cov flocculation ntawm fibers, thiab txhim kho kev tsim thiab interweaving muaj peev xwm ntawm fibers;
(3) Lub viscous quab yuam ntawm cov viscous nruab nrab ntawm cov fibers ua rau ntau fibers so thiab ua blunt ua ntej sib cuag nrog ib leeg thaum lawv tsis nplawm, yog li tsim fiber ntau tes hauj lwm nyob rau hauv lub ncua kev kawm ntawv uas txo cov kev ntxhov siab nyob rau hauv;
(4) Qhov nce ntawm viscosity ntawm ncua kev kawm ntawv kuj ua rau kom lub ncua kev kawm ntawv ntawm fiber nyob rau hauv nruab nrab thiab prolonging lub sij hawm nyob rau hauv fiber.
