zofunikira

Kagwiritsidwe Ntchito

1,4-Butanediol (BDO)ndi chinthu chofunikira kwambiri chachilengedwe chomwe chimagwiritsidwa ntchito m'njira zosiyanasiyana. Njira zazikulu zogwiritsira ntchito ndi izi:

Kupanga zinthu za polyester

• Pakupanga polybutylene terephthalate (PBT): PBT ndi pulasitiki yabwino kwambiri yopangidwa ndi polyester yopangidwa ndi thermoplastic. Ili ndi mphamvu zabwino zamakaniko, imakana dzimbiri chifukwa cha mankhwala, imateteza bwino magetsi, komanso imakhala yolimba kwambiri. Imagwiritsidwa ntchito kwambiri m'magawo amagetsi ndi zida zamagetsi popanga zida zosiyanasiyana zamagetsi ndi zolumikizira. Zigawo zina zamagalimoto, monga zogwirira zitseko zamagalimoto ndi ma bumpers, zimapangidwanso nthawi zambiri pogwiritsa ntchito zipangizo za PBT.
• Pakupanga polyurethane ya thermoplastic (TPU): TPU imaphatikiza kusinthasintha kwakukulu kwa rabara ndi kusinthasintha kosavuta kwa pulasitiki. Ndi yosatha, yosagwira mafuta, komanso yosazizira. Nthawi zambiri imagwiritsidwa ntchito popanga nsapato, mapaipi, zingwe za waya ndi zingwe, malamba oyendera mafakitale, ndi zina zotero. 1,4-Butanediol ndi chinthu chofunikira kwambiri popanga TPU, chomwe chimapatsa chinthucho kusinthasintha kwabwino komanso mphamvu zomangirira.

Kupanga kwa γ-butyrolactone ndi N-methylpyrrolidone (NMP)

• γ-butyrolactone: Ndi chosungunulira chabwino kwambiri chomwe chimasungunuka kwambiri, chimakhala ndi mphamvu yabwino yosungunulira zinthu zambiri zachilengedwe ndi ma polima. Chimagwiritsidwa ntchito kwambiri m'mafakitale opaka, inki, ndi kusindikiza ndi kupaka utoto. Ndi chinthu choyambira kupanga zonunkhira zosiyanasiyana ndi zinthu zina zopangira mankhwala, zomwe mankhwala osiyanasiyana abwino okhala ndi kapangidwe ndi ntchito zapadera amatha kupezeka pambuyo pake.
• N-methylpyrrolidone: Ndi chosungunulira cha polar aprotic, chomwe chimasonyeza mphamvu yabwino kwambiri yosungunulira zinthu zambiri za organic, inorganic, ndi polymer zomwe sizisungunuka. Ndikofunikira kwambiri popanga mabatire a lithiamu, omwe amagwiritsidwa ntchito kusungunula zomangira, zinthu zogwira ntchito zama electrode, ndi zina zotero. Chimagwiritsidwanso ntchito kwambiri popanga mankhwala ophera tizilombo, kuyeretsa zamagetsi, komanso kuchotsa ndi kulekanitsa.

Pakupanga tetrahydrofuran (THF): Tetrahydrofuran ndi chosungunulira chabwino kwambiri chomwe chimagwiritsidwa ntchito kwambiri, chokhala ndi kusungunuka kwabwino kwa zinthu zambiri zachilengedwe komanso zopangidwa ndi organic. Mu ma laboratories opanga zinthu zachilengedwe komanso machitidwe opangira mankhwala, nthawi zambiri amagwiritsidwa ntchito ngati chosungunulira kuti alimbikitse zochita. Kuphatikiza apo, ndi chinthu chopangira kupanga polytetrahydrofuran (PTMEG). PTMEG imagwiritsidwa ntchito popanga ulusi wa spandex ndi polyurethane elastomers, zomwe zimapangitsa kuti zinthu zikhale zotanuka kwambiri pa nsalu, zovala zapamwamba zamasewera, ndi mafakitale ena.
Kugwiritsa ntchito mu zamankhwala: 1,4-Butanediol ingagwiritsidwe ntchito ngati mankhwala othandizira kupanga mamolekyulu ena a mankhwala. Mwachitsanzo, mu njira zopangira mankhwala ena a steroid ndi maantibayotiki, ntchito yake ya mankhwala imagwiritsidwa ntchito popanga ndikusintha kapangidwe ka mamolekyulu a mankhwala, zomwe zimathandiza kufufuza, kupanga, ndi kupanga mankhwala atsopano.

Kulongedza ndi Kutumiza

25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga

Sungani ndi kusunga

Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
