Abubuwan da ke da inganci na maganin daskarewa bai bambanta da analogues na waje ba. Bambance-bambancen suna cikin adadin abubuwan da aka gyara kawai. Tushen sanyaya ya ƙunshi distilled ko ruwa mai narkewa, etanediol ko propanediol alcohols, abubuwan da ke hana lalata da rini. Bugu da ƙari, an ƙara reagent mai buffer (sodium hydroxide, benzotriazole) da defoamer, polymethylsiloxane.
Kamar sauran masu sanyaya, maganin daskarewa yana rage yanayin zafin ruwa kuma yana rage girman fadada kankara yayin daskarewa. Wannan yana hana lalacewa ga jaket na tsarin sanyaya injin a cikin hunturu. Yana da lubricating da anti-lalata Properties.
Menene ya haɗa a cikin maganin daskarewa?
Yawancin dozin "kayan girke-girke" na maganin daskarewa an san su - duka akan masu hana inorganic kuma akan carboxylate ko lobrid analogues. A classic abun da ke ciki na maganin daskare an bayyana a kasa, kazalika da kashi da kuma rawar da sinadaran aka gyara.
