Shellac CAS 9000-59-3
Shellac muaj cov khoom zoo heev xws li tiv taus dej noo, tiv thaiv kev xeb, tiv thaiv xeb, tiv thaiv roj, rwb thaiv hluav taws xob thiab thermoplastic. Cov kuab tshuaj zoo tshaj plaws rau cov ntsiav tshuaj shellac yog cov cawv qis uas muaj hydroxyl, xws li methanol thiab ethanol. Insoluble hauv glycol thiab glycerol, soluble hauv lye, ammonia, tab sis kuj soluble hauv cov carboxylic acids qis dua, xws li formic acid thiab acetic acid, insoluble hauv cov rog, aromatic hydrocarbons thiab lawv cov halogen derivatives, carbon tetrachloride, dej, sulfur dioxide aqueous kua. Shellac resin yog degradable nyob rau hauv ib puag ncig ntuj. Kev tso tawm mus rau hauv dej yuav ua rau muaj kev nce ntxiv ntawm cov pa oxygen ntawm cov kab mob hauv dej, ua rau cov dej eutrophication, thiab sensorially ua rau cov dej liab.

1. Hauv kev lag luam khoom noj, shellac kuj tseem siv rau hauv cov txiv hmab txiv ntoo tshiab-khaws cov txheej txheem los tsim cov yeeb yaj kiab ci, ntev lub txee lub neej ntawm cov txiv hmab txiv ntoo, thiab nce lawv cov nqi lag luam. Shellac yog siv rau hauv cov khoom qab zib thiab cov khoom qab zib txheej kom ua rau ci ntsa iab, tiv thaiv kom tsis txhob rov qab noo noo, thiab pleev xim rau phab ntsa sab hauv ntawm cov kaus poom hlau kom tiv thaiv cov khoom noj kom tsis txhob kov cov hlau.
2. Shellac siv tau dav hauv cov khoom noj, tshuaj, hluav taws xob, kua mem, tawv, metallurgy, tshuab, ntoo, roj hmab, thiab lwm yam lag luam.
3. Xim Shellac muaj zog nplaum thiab siv rau hauv ntau yam khoom siv ntoo thiab kho kom zoo nkauj.
4. Shellac siv rau hauv kev lag luam tawv ua ib qho ci ntsa iab thiab tiv thaiv, uas yog qhov qhuav sai, muaj zog sau, thiab muaj zog lo rau tawv, ua rau nws mos dua thiab ywj dua.
5. Hauv kev lag luam hluav taws xob, shellac kuj tseem siv rau hauv kev tsim cov ntawv rwb thaiv tsev, cov laug cam mica, cov khoom siv hluav taws xob hauv av, cov xim rwb thaiv tsev, cov teeb, cov teeb fluorescent, thiab cov nplaum rau cov raj hluav taws xob.
6. Feem ntau siv Shellac ua ib txheej los yog ib yam khoom siv rau cov khoom siv roj hmab hauv kev lag luam roj hmab. Txhim kho kev hnav, roj, kua qaub, dej, thiab kev rwb thaiv tsev. Ua kom qeeb qeeb ntawm kev laus thiab ua kom lub neej ntev dua.
20 kg/thawv, 50 kg/hnab los yog raws li cov neeg siv khoom xav tau.
