Konutai Acetate Anhydrous
Āhuatanga ahupūngao:
1. Karekau he tae me te maramara monoclinic kiriata prismatic ranei paura tioata ma, kakara kakara winika paku ranei, paku kawa, ngāwari ki te huarere i roto i te hau maroke me te takawai.
2. Te wai whakarewa (46.5g/100mL, 20 ℃, PH o 0.1mol/L wairewa wai he 8.87), acetone, me etahi atu, ka whakarewahia i roto i te waiwaro, engari karekau i te ether.
3.Ira whakarewa (℃): 324
Storge
1. Rokiroki ki tetahi wahi hiri me te maroke.
2. Kiia ki te peeke kirihou kua raina, peeke raranga, putea pu ranei hei koti o waho. Ko te konutai acetate he whakaheke, no reira me tiaki mai i te makuku i te wa e rokiroki ana me te kawe. Ka tino aukatihia te pa atu ki te hau hau kino, te aukati i te pa ki te ra me te ua, me te kawe ki te uhi ua.
Whakamahi
1. Te whakatau i te mata, te zinc, te konumohe, te rino, te cobalt, te antimony, te nickel me te tine. Pūmautanga matatini. He awhina, he paopao, he whakamaroke, he whakakikorua mo te acetylation.
2. Ka whakamahia hei whakatau i te mata, te zinc, te konumohe, te rino, te cobalt, te antimony, te nickel, me te tine. Ka whakamahia hei kaikawe esterification i roto i te whakahiato waro me te maha o nga waahanga penei i nga raau taero whakaahua, rongoa, taarua me te tae tae ki te mordants, buffers, reagents matū, tiaki kai, pigments, tanning, etc.
3. Ka whakamahia hei parepare, hei kai reka, hei kai reka me te kaiwhakahaere pH. Hei parepare mo te kai whakaahuru, ka taea te whakamahi 0.1%-0.3% ki te whakakore i te haunga kino me te aukati i te paheketanga hei whakapai ake i te reka. Kei a ia etahi paanga aukati, penei i te whakamahi i te 0.1% -0.3% i roto i nga hua surimi me te taro. Ka taea hoki te whakamahi hei kaihoko kawa mo te ranu whakakakahu, te sauerkraut, te mayonnaise, te keke ika, te keke, te taro, te keke piri, me etahi atu. I konatunatua ki te methyl cellulose, phosphate, me etahi atu, hei whakapai ake i te tiaki i nga hotiti, taro, piri. keke, etc.
4. Ka whakamahia hei aukati wera mo te whakakao rapa chloroprene i te whanariki. Ko te tikanga he 0.5 nga waahanga ma te papatipu. Ka taea hoki te whakamahi hei kaihoko whakawhiti mo te kāpia kararehe.
5. Ka taea te whakamahi i tenei hua ki te taapiri i te tine hiko o te kawakore, engari kaore he paanga e kitea ana i runga i te whakakikorua me te mahi hiko, a ehara i te mea he mea tika. Ko te konutai acetate te nuinga o te wa ka whakamahia hei parepare, penei i te whakakikorua konutea waikawa, te whakakikorua tine kawakore me te whakakikorua nickel electroless.
