Shellac CAS 9000-59-3
I-Shellac ineempawu ezibalaseleyo ezifana nobungqina bokufuma, ukuthintela ukubola, ukuthintela umhlwa, ukuxhathisa kweoli, ukugquma kombane kunye ne-thermoplastic.I-solvent engcono kakhulu yeepilisi ze-shellac yi-alcohol ephantsi equkethe i-hydroxyl, njenge-methanol kunye ne-ethanol.Ayinyibiliki kwi-glycol kunye ne-glycerol, i-soluble kwi-lye, i-ammonia, kodwa kwakhona i-soluble kwi-carboxylic acids ephantsi, njenge-asidi ye-formic kunye ne-acetic acid, enganyibilikiyo kumafutha, i-hydrocarbons enevumba elimnandi kunye ne-halogen derivatives, i-carbon tetrachloride, amanzi, isisombululo se-sulfur dioxide.I-resin ye-Shellac iyancipha kwindawo yendalo.Ukukhutshwa emanzini kuya kubangela ukwanda kwe-oksijini yezinto eziphilayo zamanzi, ukwenza i-eutrophication yamanzi, kwaye i-sensorially yenza amanzi abomvu.

I-1.Kwishishini lokutya, i-shellac iphinda isetyenziswe kwiziqhamo zokugcina iziqhamo ukwenza iifilimu eziqaqambileyo, ukwandisa ixesha leshelufu leziqhamo, kunye nokwandisa ixabiso labo lokuthengisa.I-Shellac isetyenziswa kwi-confectionery kunye ne-pastry coatings ukwandisa ukukhanya, ukuthintela ukufuma kwakhona, kunye nokuthambisa iindonga zangaphakathi zeetoti zetsimbi ukukhusela ukutya ekudibaneni nentsimbi.
I-2.Shellac ingasetyenziselwa ngokubanzi ukutya, amayeza, umkhosi, umbane, inki, isikhumba, isinyithi, umatshini, umthi, irabha, kunye namanye amashishini.
Ipeyinti ye-3.Shellac ine-adhesion eyomeleleyo kwaye isetyenziswe kwizinto ezininzi zokhuni eziphezulu kunye nemihlobiso.
I-4.Shellac isetyenziswe kwishishini lesikhumba njengento eqaqambileyo kunye nokukhusela, ebonakaliswe ngokumisa ngokukhawuleza, ukuzaliswa okunamandla, kunye nokubambelela ngokuqinileyo kwesikhumba, okwenza kube lula kunye nokunwebeka.
5. Kwishishini lombane, i-shellac iphinda isetyenziswe ekwenzeni i-insulating paperboard, iibhodi ze-mica laminated, i-insulators zombane eziphantsi komhlaba, i-insulating varnishes, ii-bulbs, izibane ze-fluorescent, kunye ne-solder pastes kwiibhubhu ze-elektroniki.
6.Kwishishini lomkhosi, i-shellac isetyenziswa kakhulu njenge-retarder ye-coating agents, izinto zokukhusela, kunye neziyobisi ze-gunpowder.I-Shellac ikwasetyenziselwa ukwenza izixhobo zasemkhosini ezinobungqina be-UV kunye ne-radiation-proof.
I-7.I-Shellac isetyenziswa kakhulu njengengubo yomhlaba okanye i-filler yeemveliso zerabha kwishishini lerabha.Ukuphucula ukunxiba, i-oyile, iasidi, amanzi, kunye nokugquma.Ukunciphisa inkqubo yokuguga kunye nokwandisa ixesha lokuphila.
20 kg/ibhokisi, 50 kg/bag okanye ngokweemfuno zomthengi.
