Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) ee isku darka la taaban karo

sharaxaad gaaban:

1. Sodium naphthalene sulfonate formaldehyde FDN waxa kale oo loo yaqaan naphthalene ku salaysan superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde.Muuqaalkeedu waa budada khafiifka ah ee brown.SNF superplasticizer wuxuu ka samaysan yahay naphthalene, sulfuric acid, formaldehyde iyo saldhig dareere ah, waxaana lagu sameeyaa falcelin taxane ah sida sulfonation, hydrolysis, uumi iyo dhexdhexaadin, ka dibna la qalajiyey budo.

2. Naphthalene sulfonate formaldehyde waxaa caadi ahaan loo tixraacaa sida superplasticizer for shubka, sidaas darteed waxay si gaar ah ugu habboon tahay diyaarinta shubka xoogga badan, shubka uumiga lagu daaweeyay, shubka dareeraha ah, shubka aan la taaban karin, shubka biyaha aan biyaha lahayn, shubka caagga ah, biraha birta ah iyo prestressed. shubka la xoojiyay.Intaa waxaa dheer, sodium naphthalene sulfonate formaldehyde sidoo kale waxaa loo isticmaali karaa sida kala firdhiso maqaarka, dharka iyo warshadaha dheeha, iwm. Sida soo saaraha xirfadeed ee superplasticizer naphthalene ee Shiinaha, Longou had iyo jeer waxay bixisaa tayada sare ee budada SNF iyo qiimaha warshadda dhammaan macaamiisha.

Waxqabadyada Ugu Muhiimsan

➢ SNF-A waxay siin kartaa hoobiyeyaasha xawaare caag ah oo degdeg ah, saameyn dareere sare leh, saameyn hoose oo hawo qaada ah.

➢ SNF-A waxa ay si fiican u wafaqsan tahay noocyada kala duwan ee sibidhka ama xidhayaasha gypsum-ka, waxyaabaha kale ee lagu daro sida wakiilka xumbaynta, dhumuclaha, dib u dhigista, wakiilka balaadhinta, dardargeliyaha iwm.

➢ SNF-A waxay ku habboon tahay dhoobada dhoobada ah, iskudhisyada is-hooseeya, shubka weji cadaalad ah iyo sidoo kale qallajiye dabaqa midabka leh.

Waxqabadka Alaabta

➢ SNF waxa loo isticmaali karaa sidii wakiilka qoynta ee hoobiye qaska qalalan si loo helo karti shaqo oo wanaagsan.

☑ Kaydinta iyo keenista

Waa in lagu kaydiyaa oo lagu keenaa xaalado qallalan oo nadiif ah qaabkeedii asalka ahaa kana fogaatay kulaylka.Kadib marka xirmada la furo wax soo saarka, dib-u-xidhid adag waa in la qaadaa si looga fogaado soo galinta qoyaanka.

☑ Nolosha shelf

Nolosha shelf 10 bilood.U isticmaal sida ugu dhakhsaha badan ee suurtogalka ah heerkulka sare iyo qoyaanka sare, si aanay u kordhin suurtogalnimada keega.

☑ Badbaadada alaabta

Naphthalene ku salaysan superplasticizer SNF-A kama tirsana walxaha khatarta ah. Macluumaad dheeraad ah oo ku saabsan dhinacyada badbaadada waxaa lagu bixiyaa xaashida xogta badbaadada alaabta.
