Polynaphthalene sulfonatendiye gawo lalikulu kwambiri lazakudya zamafuta a naphthalene ku China.Ndikupanga zida zochepetsera madzi za simenti zogwira mtima kwambiri.Sodium Naphthalene Formaldehydeamawerengera 85% yazomwe zimagwiritsidwa ntchito kwambiriothandizira kuchepetsa madzi. Kuchuluka kwa katundu wotumizidwa kunja kwawonjezeka mosalekeza m’zaka zaposachedwapa.Ndi chitukuko cha zomangamanga zomangamanga, naphthalene-based wothandizira kuchepetsa madzi ali ndi malo ambiri chitukuko.
Naphthalene mndandanda wa superplasticizerndi non-air-entraining superplasticizer opangidwa ndi makampani mankhwala.Dzina la mankhwala ndiSodium Naphthalene Sulphonate Formaldehyde condensate, yomwe imakhala ndi mphamvu yobalalika pa tinthu ta simenti.Ndilo lalikulu kwambiri komanso logwiritsidwa ntchito kwambiri lochepetsera madzi m'dziko langa, lomwe limaposa 70% ya kuchuluka kwa kuchepetsa madzi.
Makhalidwe a machitidwe aNaphthalene mndandanda superplasticizer:
1. Pamene mphamvu ya konkire ndi kugwa ndizofanana, kuchuluka kwa simenti kumatha kuchepetsedwa ndi 10-25%.
2. Pamene chiŵerengero cha simenti ya madzi sichinasinthe, kutsika koyambirira kwa konkire kumawonjezeka ndi oposa 10cm, ndipo kuchepetsa kuchepetsa madzi kumatha kufika 15-25%.
3.Naphthalenesulfonateali ndi mphamvu yoyambirira komanso yolimbikitsa pa konkire, ndipo kuchuluka kwake kwamphamvu ndi 20-60%.
4. Sodium naphthalene sulfonateSinthani magwiridwe antchito a konkriti ndikuwongolera bwino mawonekedwe akuthupi ndi makina a konkriti.
5. Kusinthasintha kwabwino kwa simenti zosiyanasiyana komanso kumagwirizana bwino ndi mitundu ina ya zosakaniza za konkire.
6.Naphthalene sulphonate Superplasticizermakamaka oyenera ntchito zotsatirazi konkire ntchito: madzi konkire, pulasitiki konkire, nthunzi-achiritsa konkire, impermeable konkire, madzi konkire, zachilengedwe-kuchiritsa precast konkire, zitsulo ndi prestressed kulimbikitsa konkire, mkulu-mphamvu kopitilira muyeso-mkulu-mphamvu konkire .
7. Kuwonongeka kwa konkire kumakhala kwakukulu pakapita nthawi, ndipo kutaya kwapakati pa theka la ola kuli pafupifupi 40%.
Njira zodzitetezera pakugwiritsa ntchitoPolynaphthalene sulfonate:
1. Mukamagwiritsa ntchito porous aggregate,Naphthalene Super Plasticizerm'pofunika kuwonjezera madzi ndi kusonkhezera poyamba, ndiyeno kuwonjezera madzi kuchepetsa wothandizira.
2. Pamene kugwa kuli kwakukulu, nthawi yogwedezeka siyenera kukhala yayitali kwambiri kuti tipewe kutuluka kwa magazi ndi kusanja.
