Sharaxaada Alaabta:
Sodium naphthalene sulfonate formaldehyde (SNF/PNS/FND/NSF) waxa kale oo loo yaqaan naphthalene ku salaysan superplasticizer, poly naphthalene sulfonate, sulphonated naphthalene formaldehyde. Muuqaalkeedu waa budada khafiifka ah. SNF waxay ka samaysan tahay naphthalene, sulfuric acid, formaldehyde iyo saldhig dareere ah, waxayna martaa falcelin taxane ah sida sulfonation, hydrolysis, uumi iyo dhexdhexaadin, ka dibna la qalajiyey budo. Naphthalene sulfonate formaldehyde waxaa caadi ahaan loo tixraacaa sida superplasticizer ee shubka, sidaas darteed waxay si gaar ah ugu habboon tahay diyaarinta shubka xoogga badan, shubka uumiga-la daweeyay, shubka dareeraha, shubka aan la taaban karin, shubka biyaha aan biyaha lahayn, shubka caaga ah, biraha birta ah iyo shubka la xoojiyay ee la sii xoojiyay .
Codsiga:
Heerarka yaraynta biyaha ee sarreeya. Marka saamiga biyaha-sibidhka uu yahay mid joogto ah, hoos u dhaca bilowga ah ee shubka waxaa lagu kordhin karaa in ka badan 10cm, iyo heerka dhimista biyaha ee poly naphthalene sulfonate waxay gaari kartaa ilaa 15-25%. Tan ka sii muhiimsan, marka xoogga iyo dhumucdu ay asal ahaan isku mid yihiin, polynaphthalene sulfonate waxay sidoo kale hoos u dhigi kartaa qadarka sibidhka loo isticmaalo 10-25%.
Kobcinta wanaagsan. PNS superplasticizer waxay leedahay xoog hore oo cad iyo saamaynta kobcinta shubka, tirada korodhka xoogga waa 20-60%.
La qabsiga Sodium polynaphthalene sulfonate (PNS) waxay ku habboon tahay tilmaamo kala duwan iyo moodooyinka sibidhka. Waxayna si fiican ula jaanqaadi kartaa isku-dhafka kale ee la taaban karo, tusaale ahaan, waxaa lagu dari karaa isku-darka sida wakiilka bararka, wakiilka hawo-mareenka, iyo isku-darka firfircoon sida dambaska duqsiga.
adkeysi wanaagsan Waxay si wax ku ool ah u wanaajin kartaa qaab dhismeedka daloolka shubka, si aad u wanaajiso tusmooyinka adkeysiga ee shubka sida impermeability, caabbinta karbonation iyo caabbinta baraf-dhalan.
Waxqabadka badbaadada. Poly naphthalene sulfonate waa kiimiko aan khatar ahayn oo leh astaamo badan sida kuwa aan sun ahayn, aan xanaaqin iyo kuwa aan shucaac ahayn. Wax saameyn ah oo daxalka ah kuma laha xoojinta birta.
Xidhmada: 25 kgs/bac ama sida aad codsato.
Kaydinta: Ku kaydi meel hawo leh oo qallalan.
Heerarka la fuliyay: Heerka caalamiga ah.
