Sodium Naphthalene Sulfonate Formaldehyde FDN (Na2SO4 ≤5%) oo loogu talagalay Isku-darka Shubka

sharraxaad gaaban:

1. Sodium naphthalene sulfonate formaldehyde FDN waxaa sidoo kale loo yaqaan superplasticizer ku salaysan naphthalene, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde. Muuqaalkeedu waa budada buniga ah ee khafiifka ah. SNF superplasticizer waxaa laga sameeyay naphthalene, sulfuric acid, formaldehyde iyo saldhig dareere ah, waxayna martaa taxane falcelin ah sida sulfonation, hydrolysis, condensation iyo neutralization, ka dibna waxaa la qalajiyaa budo.

2. Naphthalene sulfonate formaldehyde waxaa badanaa loogu yeeraa superplasticizer loogu talagalay shubka, sidaa darteed waxay si gaar ah ugu habboon tahay diyaarinta shubka xoogga badan, shubka uumiga lagu qalajiyey, shubka dareeraha ah, shubka aan biyuhu gelin karin, shubka biyaha aan biyuhu gelin karin, shubka balaastikada ah, baararka birta ah iyo shubka la xoojiyey ee hore loo cadaadiyey. Intaa waxaa dheer, sodium naphthalene sulfonate formaldehyde waxaa sidoo kale loo isticmaali karaa kala firdhiye ahaan warshadaha maqaarka, dharka iyo rinjiga, iwm. Iyada oo ah soo saaraha xirfadlaha ah ee superplasticizer naphthalene ee Shiinaha, Longou had iyo jeer waxay siisaa dhammaan macaamiisha budada SNF tayo sare leh iyo qiimaha warshadda.

Codsiyada

➢ La qabsi wanaagsan oo loo sameeyo dhammaan noocyada sibidhka, hagaajinta shaqada shubka, oo si weyn looga isticmaalo waddooyinka, tareennada, buundooyinka, godadka dhulka hoostiisa mara, saldhigyada korontada, biyo-xireennada, dhismayaasha dhaadheer iyo mashaariicda kale.

1. Isku darka qiyaasta 0.5%-1.0%, qiyaasta isku darka 0.75% ayaa lagula talinayaa.

2. Diyaari xalalka sida loogu baahdo.

3. Isticmaalka tooska ah ee wakiilka budada waa la ogol yahay, haddii kale ku darista wakiilka waxaa ku xiga qoyaanka biyaha (saamiga biyaha iyo sibidhka: 60%).

Bandhigyada ugu Muhiimsan

➢ SNF-A waxay keeni kartaa hoobiye xawaare degdeg ah oo balaastig ah, saameyn dareere sare leh, saameyn hawo-gelineed oo hooseeya.

➢ SNF-A waa mid si fiican ula jaanqaadi kara noocyada kala duwan ee sibidhka ama gypsum-ka, waxyaabaha kale ee lagu daro sida wakiilka ka-saarista xumbo, dhumuc-saare, dib-u-celin, wakiil ballaaran, dardar-geliye iwm.

➢ SNF-A wuxuu ku habboon yahay grout-ka foornada, isku-dhafka is-siman, shubka wejiga cad iyo sidoo kale qalabka adkaynta dabaqa midabka leh.

Waxqabadka Alaabta

➢ SNF waxaa loo isticmaali karaa sidii wakiilka qoynta ee hoobiyaha qalalan si loo helo shaqo wanaagsan.

☑ Kaydinta iyo keenista

Waa in la kaydiyaa oo la keenaa xaalad qalalan oo nadiif ah qaabkii hore ee baakadda oo ka fog kulaylka. Ka dib marka baakadda la furo si wax loo soo saaro, waa in si adag loo xidhaa si looga fogaado in qoyaanku soo galo.

☑ Muddada khaanadaha

Muddada kaydinta waxay socon kartaa 10 bilood. U isticmaal sida ugu dhakhsaha badan heerkulka sare iyo qoyaanka, si aanay u kordhin fursadda dubista.

☑ Badbaadada alaabta

SNF-A oo ku salaysan Naphthalene kama tirsana walxaha khatarta ah. Macluumaad dheeraad ah oo ku saabsan dhinacyada badbaadada waxaa lagu bixiyay Warqadda Xogta Badbaadada Agabka.
