Shellac CAS 9000-59-3
Shellac muaj cov khoom zoo xws li cov pov thawj noo noo, tiv thaiv corrosion, tiv thaiv xeb, roj tsis kam, hluav taws xob rwb thaiv tsev 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 nyob rau hauv glycol thiab glycerol, soluble nyob rau hauv lye, ammonia, tab sis kuj soluble nyob rau hauv qis carboxylic acids, xws li formic acid thiab acetic acid, insoluble nyob rau hauv cov rog, aromatic hydrocarbons thiab lawv halogen derivatives, carbon tetrachloride, dej, sulfur dioxide aqueous tov. Shellac resin yog degradable nyob rau hauv ib puag ncig ntuj. Kev tawm mus rau hauv dej yuav ua rau muaj cov pa oxygen ntxiv ntawm cov kab mob hauv dej, ua rau cov dej eutrophication, thiab sensorially ua rau cov dej liab.

1.Nyob rau hauv kev lag luam khoom noj khoom haus, shellac kuj yog siv nyob rau hauv cov txiv hmab txiv ntoo tshiab-txheej txheej los tsim cov yeeb yaj kiab ci, ua kom lub neej ntev ntawm cov txiv hmab txiv ntoo, thiab nce lawv cov nqi lag luam. Shellac yog siv rau hauv cov khoom qab zib thiab pastry coatings kom ci ntsa iab, tiv thaiv kom tsis txhob ya raws, thiab smear lub puab phab ntsa ntawm cov kaus poom hlau los tiv thaiv cov zaub mov los ntawm kev sib cuag nrog hlau.
2.Shellac tuaj yeem siv dav hauv zaub mov, tshuaj, tub rog, hluav taws xob, number case, tawv, metallurgy, machinery, ntoo, roj hmab, thiab lwm yam lag luam.
3.Shellac xim muaj zog adhesion thiab yog siv nyob rau hauv ntau qib high-qib woodware thiab decorations.
4.Shellac yog siv nyob rau hauv kev lag luam tawv ua lub ci ntsa iab thiab kev tiv thaiv tiav, uas yog ceev kom qhuav, muaj zog txhaws, thiab muaj zog adhesion rau tawv, ua rau nws softer thiab elastic dua.
5. Hauv kev lag luam hluav taws xob, shellac kuj tseem siv rau hauv kev tsim cov ntaub ntawv insulating, laminated mica boards, hauv av hluav taws xob insulators, insulating varnishes, qhov muag teev, fluorescent teeb, thiab solder pastes rau cov raj hluav taws xob.
6.Nyob rau hauv kev lag luam tub rog, shellac feem ntau yog siv los ua ib qho retarder rau txheej txheej, cov ntaub ntawv insulating, thiab tshuaj phom phom. Shellac kuj tseem siv los tsim cov khoom siv tub rog uas yog UV- thiab hluav taws xob pov thawj.
7.Shellac feem ntau yog siv los ua cov txheej txheej los yog muab tub lim rau cov khoom siv roj hmab hauv kev lag luam roj hmab. Txhim kho kev hnav, roj, kua qaub, dej, thiab rwb thaiv tsev. Txo cov txheej txheem kev laus thiab ncua lub neej.
20 kg / carton, 50 kg / hnab los yog raws li tus neeg yuav tsum tau muaj.
