Iimveliso

Izongezo ezenziwe ngokwezifiso zizikhompawundi zeekhemikhali ezikhethekileyo ezilungiselelwe ukuhlangabezana neemfuno ezithile kunye neemfuno zamashishini ahlukeneyo, kubandakanya iiplastiki, ukutya, amayeza kunye nezithambiso. Ezi zongezo ziphakamisa ukusebenza, ukuzinza, kunye nokubonakala kweemveliso zokugqibela ngokuphucula iipropati ezinjengokuqina, ukuguquguquka, ukuzinza kwe-thermal, kunye nobomi beshelufu.
Thembela iDotachem ukuhambisa izisombululo ezilungiselelweyo ezahlula imveliso yakho.

I-Methyl acetate, ekwabizwa ngokuba yi-MeOAc, i-acetic acid i-methyl ester okanye i-methyl ethanoate, ulwelo olungenambala, inevumba elimnandi. I-acetate eyenziwe yi-condensation ye-acetic acid kunye ne-methanol. Olona setyenziso luphambili lwe-methyl acetate luyinto eguquguqukayo, i-solvent enetyhefu ephantsi kwiiglues, iipeyinti, kunye nezicoci ze-nail polish. Fumana iinkcukacha zemveliso ukuqinisekisa ukuba iimveliso zethu zingasetyenziswa ngokugqibeleleyo kwinkqubo yakho yoshishino!

I-Ethyl acetate lulwelo olungenambala kunye nencasa eguqukayo, eneziqhamo. I-solvent esetyenziswa ngokubanzi, ngakumbi iipende, i-varnishes, i-lacquers, ukucoca imixube kunye neziqholo. I-acetate ye-Ethyl iyaxubana kunye ne-solvents ezininzi zezinto eziphilayo kwaye ingasetyenziselwa ukucoca imixube ukususa ioli, igrisi kunye nomhlaba.

Ibutyl acetate lulwelo olungenambala nevumba elimnandi. I-butyl acetate inyibilika kancinane emanzini kwaye inokuxutywa notywala, i-ether kunye nezinye izinyibilikisi eziqhelekileyo eziphilayo. Xa kuthelekiswa ne-homologue yayo esezantsi, i-butyl acetate ayinyibiliki kancinci emanzini kwaye kunzima ngakumbi ukwenza i-hydrolyze. Nangona kunjalo, phantsi kwesenzo se-acids okanye iziseko, i-acetic acid kunye ne-butanol i-hydrolyzed. I-butyl acetate sesona sinyibilikiyo sibaluleke kakhulu esiphakathi kwishishini lokugquma.

I-Tetrachloroethene lulwelo olungenambala olunevumba elifana ne-ether kwaye lunokunyibilikisa izinto ezahlukeneyo. Isetyenziswa ngokubanzi ekucoceni okomileyo kwamalaphu kunye nokuchithwa kwesinyithi, kunye nokuveliswa kwamanye amachiza.

Iasidi yePropionic lulwelo olungenambala olunevumba elikhuthazayo. I-Propionic acid yi-short-chain saturated fatty acid, ene-acidic ebuthakathaka kwisisombululo esinamanzi, kodwa i-corrosive kakhulu, kwaye umphunga uyacaphukisa ulusu kunye nomgudu wokuphefumula. Yimathiriyeli ekrwada yokwenziwa kwezinto eziphilayo, ikakhulu esetyenziselwa ukuhlanganiswa kweemveliso zepropionate kunye ne-ester.
