Tsananguro yeChigadzirwa

Hunhu hwemakemikari

Diethanolamine ibase reorganic iro rave richishandiswa semushonga unobvisa makemikari mumuviri. Rinogona zvakare kushandiswa semushonga wekudzivirira masero, rine pH yakakwana inosvika pH 9, kana riine HCl kana imwe acid. Mamwe mashandisirwo anosanganisira: "kukwesha" magasi, semushonga wemakemikari, semushonga unonyorovesa muviri kana mushonga unonyorovesa muviri.

Mashandisirwo

Diethanolamine yakafanana netriethanolamine inoshandiswa sesurfactant. Ine mukana wekuti inhibitor yengura kuburikidza ne chemisorption.

Kukwesha magasi sezvinoratidzwa pasi peethanolamine. Diethanolamine inogona kushandiswa nemagasi anotsemuka uye magasi emarasha kana mafuta ane carbonyl sulfide iyo inogona kuita ne monoethanolamine. Semakemikari erabha ari pakati nepakati. Mukugadzira zvinhu zvinoshanda pamusoro pemachira zvinoshandiswa mumishonga yemishonga, mishonga yekuuraya zvipembenene, petroleum demulsifiers. Se emulsifier uye dividing agent mumakemikari akasiyana-siyana ekurima, zvizoro, uye mishonga. Mukugadzira mafuta ekugadzira machira. Se humectant uye softening agent. Mukugadzira organic syntheses.

Diethanolamine inoshandiswa mukugadzira zvinhu zvinoshanda pamusoro pevhu uye mafuta ekugadzira machira; semushonga wemakemikari erabha; semushonga we emulsifier; semushonga we humectant uye wekunyorovesa; semushonga wekuchenesa mumapendi, shampoos, nezvimwe zvinochenesa; uye semushonga wepakati muma resin nema plasticizers.
