Shellac CAS 9000-59-3
Shellac waxay leedahay sifooyin aad u fiican sida u adkeysiga qoyaanka, ka hortagga daxalka, ka hortagga miridhku, iska caabbinta saliidda, dahaarka korontada iyo thermoplastic. Xaliyaha ugu fiican ee kiniiniyada shellac waa alkohol heer hoose ah oo ka kooban hydroxyl, sida methanol iyo ethanol. Lama milmi karo glycol iyo glycerol, waxaa lagu milmi karaa lye, ammonia, laakiin sidoo kale waxaa lagu milmi karaa asiidhyada carboxylic ee hooseeya, sida formic acid iyo acetic acid, aan lagu milmi karin dufanka, hydrocarbons-ka udgoonka leh iyo waxyaabaha ka soo baxa halogen-ka, carbon tetrachloride, biyaha, xalka biyaha ee sulfur dioxide. Shellac resin waa la burburin karaa deegaanka dabiiciga ah. Daadinta biyaha waxay sababi doontaa koror ku yimaada oksijiinta noolaha biyaha, waxay ka dhigi doontaa biyaha inay u adkaystaan, waxayna si dareen leh uga dhigi doontaa biyaha casaan.

1. Warshadaha cuntada, shellac waxaa sidoo kale loo isticmaalaa dahaarka cusub ee miraha si loo sameeyo filimaan dhalaalaya, loo dheereeyo cimriga miraha, loona kordhiyo qiimahooda ganacsi. Shellac waxaa loo isticmaalaa dahaarka macmacaanka iyo keega si loo kordhiyo dhalaalka, looga hortago qoyaanka inuu soo noqdo, loona mariyo derbiyada gudaha ee qasacadaha birta si looga hortago in cuntadu ay taabato birta.
2. Shellac waxaa si weyn loogu isticmaali karaa cuntada, daawada, korontada, khad, maqaar, biraha, mashiinnada, qoryaha, cinjirka, iyo warshadaha kale.
3. Rinjiga Shellac wuxuu leeyahay dhejis xooggan waxaana loo isticmaalaa alwaaxyo iyo qurxin heer sare ah.
4. Shellac waxaa loo isticmaalaa warshadaha maqaarka si ay u noqoto dhammaystir dhalaalaya oo ilaalin leh, oo lagu garto qalajin degdeg ah, buuxin xoog leh, iyo dhegdheg adag oo maqaarka ah, taasoo ka dhigaysa mid jilicsan oo dabacsan.
5. Warshadaha korontada, shellac waxaa sidoo kale loo isticmaalaa soo saarista warqadaha dahaarka leh, looxyada mica ee la dahaadhay, dahaarka korontada ee dhulka lagu shito, varnishes dahaarka leh, nalalka, nalalka fluorescent-ka ah, iyo koolada alxanka ee tuubooyinka elektarooniga ah.
6. Shellac waxaa inta badan loo isticmaalaa dahaarka dusha sare ama buuxinta alaabada caagga ah ee warshadaha caagga. Hagaajinta xirashada, saliidda, aashitada, biyaha, iyo dahaarka. Hagaaji habka gabowga oo kordhi cimriga.
20 kg/kartoon, 50 kg/bac ama iyadoo loo eegayo shuruudaha macaamiisha.
