Nrog rau kev txhim kho thev naus laus zis thiab kev lag luam, nrog rau kev txhim kho engineering zoo, lub luag haujlwm ntawm tus neeg saib xyuas dej-txo hauv kev ua vaj tse tau dhau los ua qhov tseem ceeb.Hnub no kuv yuav coj koj los nkag siab txog lub luag haujlwm tseem ceeb ntawm tus neeg saib xyuas dej txo qis hauv kev tsim kho kev lag luam.
High range dej txo cov kua nplaum yog muab faib ua: (1)lignosulfonates;(2) polycyclic aromatic ntsev;(3) dej-soluble resin sulfonates.Naphthalene superplasticizer, aliphatic superplasticizer, amino superplasticizer, polycarboxylicacid superplasticizer, lwm.
Daim ntawv zoo li muab faib ua kua thiab hmoov.Cov tsos mob yog muab faib ua kua thiab hmoov.Cov ntsiab lus ntawm cov dej feem ntau yog 20%, 40% (tseem hu ua niam cawv), 60%, thiab cov ntsiab lus ntawm cov hmoov feem ntau yog 98%.Raws li cov dej txo thiab txhim kho muaj peev xwm ntawmdej txo tus neeg sawv cev, nws tau muab faib ua tus neeg saib xyuas dej zoo tib yam (tseem hu ua plasticizer, dej txo tus nqi tsis tsawg dua 8%, sawv cev los ntawm lignosulfonate), superplasticizer (tseem hu ua superplasticizer) Plasticizer, cov dej txo qis tsis tsawg dua 14%, suav nrog naphthalene, melamine, sulfamate, aliphatic, thiab lwm yam) thiab cov dej-txo cov neeg ua haujlwm siab (dej txo tus nqi tsis tsawg dua 25%, nrog polycarboxylic acid Nws yog sawv cev los ntawm cov dej txo tus neeg sawv cev), thiab muab faib ua thaum ntxov-lub zog. hom, hom qauv thiab retarder.
Tom qab ntxiv cov pob zeb sib xyaw, nws tuaj yeem cuam tshuam cov cement hais, uas tuaj yeem txhim kho nws txoj haujlwm ua haujlwm, txo cov dej hauv chav tsev, thiab txhim kho cov kua dej ntawm cov pob zeb sib xyaw;los yog txo cov cement noj thiab txuag cov cement.
Peb lub tuam txhab yog cov chaw tsim khoom ntawm cov dej-txo cov neeg ua haujlwm, nrog ob lub chaw tsim khoom tsim khoom, rau ntau qhov kev tsim khoom loj, pab pawg R & D, kev tsim kho thiab kev pabcuam dawb, tshwj xeeb hauv cov khoom sib xyaw ua ke uas ua rau cov neeg siv khoom yooj yim.
