Imikhiqizo

I-Thioglycolic acid CAS No. 34590-94-8

Incazelo emfushane:

I-Thioglycollic acid (TGA) isetshenziswa kakhulu njengempahla eluhlaza yokuqeda ingubo kanye nesisombululo soku-ayina esibandayo. I-TGA inezici zokusabela zazo zombili i-hydroxyl acid neqembu le-sulfhydryl, ukusabela okubaluleke kakhulu ukusabela nge-disulfide. Ikakhulukazi, isabela nge-cystine ezinweleni ngaphansi kwezimo ze-alkaline, inqamula isibopho (-SS-) se-cystine, futhi ikhiqize i-cysteine ​​Chemicalbook acid okulula ukuyigoqa. Isetshenziswa kakhulu njenge-ejenti yokugoqa, i-ejenti yokususa izinwele, ubuthi be-polyvinyl chloride obuphansi noma isinzinzisi esingenabuthi, isiqalisi se-polymerization, i-accelerator ne-ejenti yokudlulisa amaketango, i-ejenti yokwelashwa kwendawo yensimbi. Ngaphezu kwalokho, i-thioglycolic acid iyi-reagent ezwelayo ekunqumeni insimbi, i-molybdenum, i-aluminium, ithini, njll. Ingasetshenziswa futhi njenge-crystallization nucleating ejenti yokucubungula nokubumba kwe-polypropylene, kanye ne-modifier ye-coatings, imicu, kanye i-ejenti yokuqeda ngokushesha izingubo zokulala.

Isicelo

Isetshenziswa kakhulu njenge-ejenti yokugoqa, i-ejenti yokususa izinwele, ubuthi be-polyvinyl chloride obuphansi noma isinzinzisi esingenabuthi, isiqalisi se-polymerization, i-accelerator ne-ejenti yokudlulisa amaketango, i-ejenti yokwelashwa kwendawo yensimbi.

I-Dipropylene glycol methyl ether iyisincibilikisi esiphilayo esinezinhlobonhlobo zokusetshenziswa kwezimboni nezentengiso.Ithola ukusetshenziswa njengendlela ehlukile engaguquguquki kakhulu kune-propylene glycol methyl ether namanye ama-glycol ether. Umkhiqizo wezohwebo ngokuvamile uyingxube yama-isomer amane.

Isetshenziswa njenge-solvent ye-nitrocellulose, i-ethyl cellulose, i-polyvinyl acetate, njll.; njenge-solvent ye-nitrocellulose, i-ethyl cellulose, i-polyvinyl acetate, njll., njenge-solvent yamapende namadayi, nanjengengxenye ye-brake fluid. Isetshenziswa njenge-solvent yokuphrinta uyinki noqweqwe lwawo, iphinde isetshenziswe njenge-solvent yokugeza amafutha okusika namafutha okusebenza. Isetshenziswa njenge-ejenti yokuhlanganisa amapende ahlanjululwe asekelwe emanzini (okuvame ukuxutshwa);

Izinyibilikisi ezisebenzayo zamapende asekelwe emanzini;

I-solvent ne-ejenti ehlanganisayo yabahlanzi basendlini nabasezimbonini, izinto ezikhipha amafutha nopende, izinto zokuhlanza insimbi, izihlanzi eziqinile;

Izinyibilikisi eziyisisekelo kanye nama-ejenti ahlanganisayo woyinki wokuphrinta wesikrini asuselwa ku-solvent;

I-ejenti yokuhlanganisa kanye ne-solvent yezindwangu zedayi ye-vat;

I-ejenti yokuhlanganisa kanye ne-ejenti yokunakekelwa kwesikhumba ekwenziweni kwezimonyo; ukuzinza kwezibulala-zinambuzane zezolimo; i-coagulant yezibani zomhlabathi.

Izindawo Zokufaka Isicelo

Izindwangu:I-solvency enhle yama-resin afaka ama-acrylics, ama-epoxies, ama-alkyds, ama-nitrocellulose resins nama-polyurethane resins. Ingcindezi yomhwamuko ephansi uma kuqhathaniswa nezinga lokuhwamuka kancane, ukungezwani okuphelele kwamanzi kanye nezakhiwo ezinhle zokuhlanganisa.

I-ejenti yokuhlanza: ukungezwani okuphansi kwendawo, iphunga elimnandi eliphansi kanye nezinga lokuhwamuka eliphansi. I-solubility enhle yazo zombili izinto ze-polar nezingezona ze-polar, kuyisinqumo esihle sokukhipha i-dewaxing nokuhlanza phansi.

Inzuzo

Izinga lomkhiqizo, inani elanele, ukulethwa okuphumelelayo, izinga eliphezulu lesevisi Inenzuzo kune-amine efanayo, i-ethanolamine, ngokuthi ukugxilisa okuphezulu kungase kusetshenziselwe amandla afanayo okugqwala. Lokhu kuvumela abacwengi ukuthi bakhuhle i-hydrogen sulfide ngenani eliphansi le-amine elijikelezayo ngokusetshenziswa kwamandla sekukonke.
