Keeb kwm ntawm naphthalene series superplasticizer
Lub admixture uas tuaj yeem txo cov dej sib tov zoo nyob rau hauv cov xwm txheej uas cov pob zeb poob qis yog qhov zoo ib yam yog hu ua naphthalene-based high-efficiency water reducer. Tus editor hauv qab no yuav qhia rau koj paub txog cov laj thawj rau kev txhim kho ntawm naphthalene-based high-efficiency water reducers:
Ib tiam ntawm naphthalene-based high-efficiency water reducers-naphthyl-naphthalene-based high-efficiency water-reducers thiab melamine resin-based naphthalene-based high-efficiency water-reducers tau tsim tawm thaum xyoo 1960s. Lub lignosulfonate tau tsim los yog tus neeg sawv cev - nws tau raug kho kom zoo, yog li nws tseem hu ua superplasticizer.
Lub thib ob tiam naphthalene-raws li high-efficiency dej reducer yog sulfamate, txawm hais tias nws yog tom qab thib peb tiam naphthalene-raws li high-efficiency dej-reducer-polycarboxylate nyob rau hauv chronological order.
Cov graft copolymer nrog ob pawg sulfonic acid thiab carboxylic acid pawg yog ib qho tseem ceeb heev ntawm cov thib peb tiam naphthalene-raws li high-efficiency water reducers, thiab nws kuj yog ib tug high-kev ua tau zoo dej reducer nrog kev ua tau zoo heev.
