ʻO Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) no ka hoʻohuihui ʻana o ka sima

ʻO Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) no ka Concrete Admixture Kiʻi i hōʻike ʻia

wehewehe pōkole:

1. ʻO ka sodium naphthalene sulfonate formaldehyde FDN ua kapa ʻia hoʻi ʻo naphthalene based superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde. ʻO kona helehelena ka pauka ʻeleʻele māmā. Hana ʻia ka SNF superplasticizer me ka naphthalene, sulfuric acid, formaldehyde a me ke kumu wai, a ke hele nei i kahi moʻo o nā hopena e like me ka sulfonation, hydrolysis, condensation a me ka neutralization, a laila maloʻo i loko o ka pauka.

2. Ua kapa pinepine ʻia ʻo Naphthalene sulfonate formaldehyde he superplasticizer no ka sima, no laila he kūpono loa ia no ka hoʻomākaukau ʻana o ka sima ikaika kiʻekiʻe, ka sima i hoʻōla ʻia i ka mahu, ka sima wai, ka sima impermeable, ka sima wai ʻole, ka sima plasticized, nā kila kila a me ka sima i hoʻoikaika ʻia. Eia kekahi, hiki ke hoʻohana ʻia ka sodium naphthalene sulfonate formaldehyde ma ke ʻano he mea hoʻolaha i nā ʻoihana ʻili, lole a me ka dye, a pēlā aku. Ma ke ʻano he mea hana ʻoihana o ka naphthalene superplasticizer ma Kina, hāʻawi mau ʻo Longou i ka pauka SNF kiʻekiʻe a me nā kumukūʻai hale hana no nā mea kūʻai aku āpau.
