Izinciphisi Zamanzi Eziphezulu Ze-Polycarboxylate Superplasticizer Zokwakha Ubumba Oluqinile
1. Ama-super plasticizer angama-surfactants e-hydrodynamic (ama-surface reactive agents) okufeza ukusebenza okuphezulu ngesilinganiso esincishisiwe se-w/c ngokunciphisa ukungqubuzana phakathi kwezinhlayiya.
2. Ama-Superplasticizer, aziwa nangokuthi ama-high range water reducers, ayizithasiselo ezisetshenziselwa ukwenza ukhonkolo onamandla noma ukubeka ukhonkolo ozihlanganisayo. Ama-plasticizer ayizinhlanganisela zamakhemikhali ezivumela ukukhiqizwa kokhonkolo olunokuqukethwe kwamanzi okungaphansi ngo-15%.
3. I-PC seris iyi-polymer ye-Poly carboxylate ethuthukisiwe enomphumela wokuhlakazeka onamandla kakhulu futhi ikhombisa ukuhlukaniswa kokunciphisa amanzi kanye nokopha, yengezwa ekukhiqizweni kwekhonkrithi esebenza kahle futhi ihlanganiswe nesamente, i-aggregate, kanye nokuxuba.

I-Sulphonated Melamine Formaldehyde (SMF) Superplasticizer ye-Concrete Admixtures
1. I-Sulphonated Melamine Formaldehyde (SMF) ibizwa nangokuthi i-Sulfonated Melamine Formaldehyde, i-Sulphonated Melamine Formaldehyde Condensate, i-Sodium Melamine Formaldehyde. Lulunye uhlobo lwe-superplasticizer ngaphandle kwe-Sulphonated Naphthalene Formaldehyde kanye ne-Polycarboxylate superplasticizer.
2. Ama-super plasticizer angama-surfactants e-hydrodynamic (ama-surface reactive agents) okufeza ukusebenza okuphezulu ngesilinganiso esincishisiwe se-w/c ngokunciphisa ukungqubuzana phakathi kwezinhlayiya.
3. Njengezingxube zokunciphisa amanzi, i-Sulfonated melamine formaldehyde (SMF) iyi-polymer esetshenziswa kuma-cement kanye namafomula asekelwe ku-plaster ukunciphisa okuqukethwe kwamanzi, ngenkathi kwandiswa ukugeleza nokusebenza kahle kwengxube. Kuma-concrete, ukungezwa kwe-SMF ekwakhiweni kwengxube efanele kuholela ekujuleni okuphansi, amandla aphezulu okusebenza, kanye nokumelana okuthuthukisiwe ezindaweni ezinolaka.

I-Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) Yokuhlanganiswa Kokhonkolo
1. I-sodium naphthalene sulfonate formaldehyde FDN ibizwa nangokuthi i-naphthalene based superplasticizer, i-poly naphthalene sulfonate, i-sulphonated naphthalene formaldehyde. Ukubukeka kwayo kuyimpuphu ensundu ekhanyayo. I-SNF superplasticizer yenziwe nge-naphthalene, i-sulfuric acid, i-formaldehyde kanye nesisekelo soketshezi, futhi idlula ochungechungeni lwezimo ezifana ne-sulfonation, i-hydrolysis, i-condensation kanye ne-neutralization, bese yomiswa ibe yimpuphu.
2. I-formaldehyde ye-naphthalene sulfonate ivame ukubizwa ngokuthi i-superplasticizer yekhonkrithi, ngakho-ke ifaneleka kakhulu ekulungiseleleni ikhonkrithi enamandla aphezulu, ikhonkrithi eqiniswe ngomusi, ikhonkrithi ewuketshezi, ikhonkrithi engangeni manzi, ikhonkrithi engangeni manzi, ikhonkrithi eyenziwe ngepulasitiki, imigoqo yensimbi kanye nekhonkrithi eqinisiwe ecindezelwe. Ngaphezu kwalokho, i-sodium naphthalene sulfonate formaldehyde ingasetshenziswa futhi njengesihlanzi embonini yesikhumba, yendwangu kanye neyedayi, njll. Njengomkhiqizi ochwepheshe we-naphthalene superplasticizer eShayina, uLongou uhlala ehlinzeka ngamanani aphezulu e-SNF powder kanye nefektri kuwo wonke amakhasimende.
