Thioglycolic acid CAS No. 34590-94-8

Kufotokozera Kwachidule:

Thioglycollic acid (TGA) amagwiritsidwa ntchito makamaka ngati zopangira zopangira bulangeti komanso njira yoziziritsira kuzizira. TGA ili ndi machitidwe a gulu la hydroxyl acid ndi sulfhydryl, zomwe zimafunikira kwambiri ndi zomwe zimachitika ndi disulfide. Makamaka, imachita ndi cystine mutsitsi pansi pamikhalidwe yamchere, imachotsa (-SS-) chomangira cha cystine, ndikupanga cysteine ​​Chemicalbook acid yomwe ndiyosavuta kupindika. Amagwiritsidwa ntchito makamaka ngati curling wothandizira, wochotsa tsitsi, polyvinyl chloride otsika kawopsedwe kapena osakhala poizoni stabilizer, polymerization initiator, accelerator ndi unyolo kutengerapo wothandizira, zitsulo pamwamba mankhwala wothandizira. Komanso, thioglycolic asidi ndi reagent tcheru kudziwa chitsulo, molybdenum, zotayidwa, malata, etc. Angagwiritsidwenso ntchito ngati crystallization nucleating wothandizila kwa polypropylene processing ndi akamaumba, komanso modifier kwa zokutira, ulusi, ndi womaliza mwachangu zofunda.

Kusungirako Kusunga pamalo ozizira, mpweya wokwanira, wouma, wotalikirana ndi gwero lamoto, zonyamula ndi kutsitsa ziyenera kusungidwa molingana ndi zomwe zimaperekedwa ndi mankhwala oopsa omwe amayaka.

Kugwiritsa ntchito

Amagwiritsidwa ntchito makamaka ngati curling wothandizira, wochotsa tsitsi, polyvinyl chloride otsika kawopsedwe kapena osakhala poizoni stabilizer, polymerization initiator, accelerator ndi unyolo kutengerapo wothandizira, zitsulo pamwamba mankhwala wothandizira.

Dipropylene glycol methyl ether ndi organic solvent ndi ntchito zosiyanasiyana za mafakitale ndi zamalonda.Imapeza kugwiritsidwa ntchito ngati njira yochepetsetsa ya propylene glycol methyl ether ndi ma glycol ethers. Zogulitsa zamalonda nthawi zambiri zimakhala zosakanikirana ndi ma isomers anayi.

Amagwiritsidwa ntchito ngati zosungunulira za nitrocellulose, ethyl cellulose, polyvinyl acetate, etc.; monga zosungunulira za nitrocellulose, ethyl cellulose, polyvinyl acetate, etc., monga zosungunulira za utoto ndi utoto, komanso ngati chigawo cha brake fluid. Amagwiritsidwa ntchito ngati chosungunulira chosindikizira inki ndi enamel, komanso amagwiritsidwa ntchito ngati chosungunulira pakutsuka mafuta odulira ndi mafuta ogwirira ntchito. Amagwiritsidwa ntchito ngati cholumikizira cha utoto wothira madzi (nthawi zambiri wosakanikirana);

Zosungunulira zogwira ntchito za utoto wamadzi;

Zosungunulira ndi zolumikizira zotsuka m'nyumba ndi m'mafakitale, zochotsera mafuta ndi utoto, zotsukira zitsulo, zotsukira pamwamba;

zosungunulira Basic ndi lumikiza wothandizira zosungunulira zochokera chophimba inki kusindikiza;

Coupling agent ndi zosungunulira za nsalu za utoto wa vat;

Coupling wothandizila ndi khungu chisamaliro mankhwala formulations zodzikongoletsera; stabilizer wa mankhwala ophera tizilombo; coagulant kwa zowunikira pansi.

Malo Ofunsira

Zopaka: Kusungunuka kwabwino kwa ma resins kuphatikiza ma acrylics, epoxies, alkyds, nitrocellulose resins ndi polyurethane resins. Kuthamanga kwa nthunzi wochepa komanso kusungunuka kwapang'onopang'ono, kusakanikirana kwamadzi kwathunthu ndi katundu wabwino wophatikiza.

Zoyeretsera: kutsika kwapamtunda, kununkhira kochepa komanso kutsika kwamadzi. Kusungunuka kwabwino kwa zinthu zonse za polar komanso zomwe si za polar, ndi chisankho chabwino pakutsitsa ndi kuyeretsa pansi.

Ubwino

Ubwino wazinthu, kuchuluka kokwanira, kuperekera kogwira mtima, ntchito yabwino kwambiri Imakhala ndi mwayi wopitilira amine wofanana, ethanolamine, chifukwa kuchuluka kwakukulu kungagwiritsidwe ntchito pakuwonongeka komweko. Izi zimathandiza oyenga kutsuka hydrogen sulfide pamlingo wocheperako wozungulira wa amine osagwiritsa ntchito mphamvu zonse.
