    Waa maxay Naphthalene CAS 91-20-3?

    Naphthalene waa muraayad monoclinic ah oo dhalaalaya oo aan midab lahayn. Waxay leedahay ur daamur oo xooggan. Way fududahay in lagu sarreeyo heerkulka qolka. Waa mid aan lagu milmi karin biyaha, laakiin waxay ku milmaan ether, ethanol, chloroform, carbon disulfide, benzene, iwm. Naphthalene waa hydrocarbon giraanta ugu muhiimsan ee warshadaha. Inta badan waxaa loo isticmaalaa in lagu soo saaro phthalic anhydride, naphthols kala duwan, naphthylamines, iwm. Waa dhex dhexaad u ah soo saarista xabagta synthetic, balaastikada, midabaynta, surfactants, fiilooyinka synthetic, dahaarka, sunta cayayaanka, daawooyinka, udgoon, caag lagu daro iyo cayayaanka.

    Codsiga

    1.Dye dhexdhexaadiye
    Naphthalene waxay door muhiim ah ka ciyaartaa wax soo saarka dheeha, gaar ahaan dheeha dhexdhexaadka ah. Naphthalene warshadeed waa shey muhiim ah oo loogu talagalay soo saarista midabyo iyo midabyo kala duwan, sida midabada indigo iyo midab jaalaha ah. Intaa waxaa dheer, naphthalene waxaa loo rogi karaa dhexdhexaadiyeyaasha dheeha sida β-naphthol, kuwaas oo loo sii isticmaalo soo saarista midabada iyo midabada. Wadamo kala duwani waxay leeyihiin qaybo kala duwan oo isticmaalka naphthalene, laakiin dhexdhexaadiyeyaasha dheeha ayaa had iyo jeer meel ku leh.
    2.Rubber additives
    Naphthalene waxaa inta badan loo isticmaalaa wax lagu daro habaynta cinjirka. Isticmaalkan ayaa ka dhigan qiyaastii 15% wadarta isticmaalka naphthalene. Waxyaabaha lagu daro caaggu waxay door muhiim ah ka ciyaaraan wax soo saarka caagga. Waxay hagaajin karaan sifooyinka caagga, sida kor u qaadida xooggiisa, ductility ama caabbinta cimilada. Sida wax lagu daro caag ah, naphthalene waxay siisaa hawlo gaar ah iyo sifooyin alaabada caagga ah, taasoo ka dhigaysa inay ku habboon yihiin xaaladaha kala duwan ee codsiga.
    3. Cayayaanka
    Naphthalene waxay leedahay codsiyo gaar ah oo ku saabsan goobta cayayaanka. In kasta oo isticmaalka naphthalene uu ku kala duwan yahay waddan ka waddan, cayayaan-dillaacyada ayaa ah qiyaastii 6% isticmaalkeeda. Gaar ahaan, wadamada qaarkood, sida Maraykanka, saamiga loo isticmaalo soo saarista sunta cayayaanka waa mid aad u badan. Intaa waxaa dheer, anthracene sidoo kale waxaa loo isticmaalaa sidii cayayaanka, oo la nool isticmaalka kale sida alaabta iftiinka iyo midabada. Codsiyadani waxay muujinayaan muhiimada naphthalene iyo anthracene u leeyihiin xakamaynta cayayaanka ee beeraha iyo dhirta.
