Naphthalene Superplasticizer

naphthalene superplasticizer ndi pulasitiki wapamwamba kwambiri komanso chochepetsera madzi chomwe chimakhazikitsidwa pa molekyulu yolemera kwambiri ya sulphonated naphthalene formaldehyde condensate.. Imawonjezera mwachangu kugwira ntchito kwa konkriti yogwiritsidwa ntchito mu matailosi a simenti & kuponya mayunitsi a precast.

Oyenera mitundu yonse ya konkire, itha kugwiritsidwa ntchito mumitundu yosiyanasiyana ndi mitundu. Ikhoza kupangidwa ndi mitundu yosiyanasiyana ya ma admixtures.

Itha kugwiritsidwa ntchito popanga konkriti yoyenda, konkire yamphamvu ndi konkriti yokweza nthunzi. Kutentha kwake kochepa kogwira ntchito ndi 0 digiri C, ndipo mphamvu zake zitha kuonjezedwa 20-60%.

Mankhwalawa amapangidwa ndi sulphonation, hydrolysis, condensation ndi neutralization reaction ya naphthalene ndi formaldehyde. Lilibe kloridi, zomwe zimakwaniritsa zofunikira za mankhwala osakanikirana a konkire: Chithunzi cha ASTM C 494, Mtundu F; Chithunzi cha ASTM C 1017 ndi GB8076-1997.

naphthalene superplasticizer makamaka imakhala ndi 25-45% anaikira sulfuric asidi, 10-35% mafakitale naphthalene, 5-10% ndi mafakitale byproduct sodium sulfonate, 6-10% formaldehyde ndi 7-10% cha madzi. Ikhoza kukonzedwa popanda mankhwala pa dinaphthol mafakitale byproduct zinyalala, zomwe zimapulumutsa mphamvu komanso kuteteza chilengedwe.

PNS superplasticizer ili ndi mitundu yambiri yochepetsera madzi komanso kulimbikitsa mphamvu, kusinthika kwabwino kwa konkriti, otsika alkali ndi chiyero kwambiri. Itha kuphatikizidwanso ndi zosakaniza zina za konkriti ndipo ndizosavuta kugwiritsa ntchito.

Amagwiritsidwa ntchito kwambiri pokonzekera konkire yamphamvu kwambiri, kuyenda konkriti, konkire yosasunthika komanso konkriti yokwezera nthunzi. Ikhoza kupangidwa ndi mitundu yambiri yosakaniza, monga kutupa wothandizira, mpweya etraining wothandizira, yogwira admixture ndi zina zotero. Ikhoza kuchepetsa kuchuluka kwa madzi, kupititsa patsogolo kukula kwa mphamvu ndi rheology ya konkire, pangitsa konkriti kukhala yamadzimadzi, onjezerani kuthamanga kwa magazi, ndi zina.
