muchidimbu
N-methyl pyrrolidinone yepfupi, molecular formula: C5H9NO, Chirungu: 1-methyl-2-PyrrolidinOne, chitarisiko chisina ruvara kusvika kuchiedza chero chinopenya mvura, ine kunhuhwirira kweammonia, kukanganiswa nemvura mune chero chikamu, inonyungudika muether, acetone uye ester, halogenated hydrocarbon, aromatic hydrocarbon and other organic solvents, Anenge akanyatsosanganiswa nezvose zvinonyungudutsa Chemicalbook, boiling point 204℃, flash point 91℃, hygroscopic, stable chemical properties, hapana ngura kune carbon steel, aruminiyamu, inoodza zvishoma kusvika kumhangura.Iine mabhenefiti e-low viscosity, yakanaka kemikari uye kugadzikana kwekupisa, yakakwirira polarity, kuderera kuderera, kusingaperi miscibility nemvura uye akawanda organic solvents, etc. Ichi chigadzirwa chinonzi micro drug, iyo inobvumirwa muganhu wekugadzirisa mumhepo ndeye 100PP.
Main kushandiswa
(1.) Industrial giredhi:
Mafuta ekunatsa, mafuta ekuzora antifreeze agent, syngas desulfurization, zvemagetsi zvekudzivirira, mishonga yekurima sora, mishonga yekuuraya zvipembenene, PVC muswe kudzoreredza gasi, machira epamusoro-giredhi, inki, kugadzirwa kwepigment yezvinowedzera uye zvinoparadzira.Semuenzaniso, inoshandiswa kubvisa aromatics mumafuta ekuzora kuzadzisa chinangwa chekuchenesa mafuta ekuzora;Nekuda kwekunyungudika kukuru kweNMP resin, sechinhu chinonyungudutsa chekugadzirisa resin chinogona kunyatso shandiswa mukugadzira machira, pendi yepasi, varnish, composite coating film, integrated circuit enameled wire insulation materials, fiber machira nemanamira nezvimwe zvigadzirwa.
(2.)Nhoroondo:
Kudhirowa uye kudzoreredzwa kwezvinhu zvakakosha organic zvinhu, senge acetylene kudhirowa uye butadiene, isoprene, aromatics uye kumwe kubviswa.Inogona kushandiswa sechinhu chinonyungudutsa kudzoreredza acetylene kubva kugasi rechisikigo kana mwenje naphtha pyrolysis gasi.Sechigadziro chekuparadzanisa uye kupora kwepamusoro-kuchena butadiene kubva pakupwanya C4 hydrocarbon, chiyero chekudzorera chiri 97%, uye kuchena kwebutadiene yakadzorerwa i99.7%.Sechinodhirowa chekudzoreredza kwepamusoro-kuchena isoprene kubva pakutsemuka C5 hydrocarbon, kuchena kuchena kweisoprene i99%.Nekuda kwekunyungudika kwayo kwakanyanya uye kuderera kwemutsindo wekunhuhwirira, iyo yekubvisa mumiriri kurasikirwa mwero yakaderera uye mwero wekudzoreredza wearomatics wakakwira.
(3.) Reagent level:
Yakabatanidzwa dunhu, hard disk uye zvimwe zvinodiwa zvekutonga kwakasimba kwesimbi ions uye zvimedu zveindasitiri ye deoiling, degreasing, dewaxing, polishing, kudzivirira ngura, pendi, senge photoresist yekubvisa mvura, IC semiconductor industry precision instruments, LCD liquid crystal materials, PCB yakadhindwa redunhu bhodhi, hard disk kuchenesa;Pamwe chete neyakagadzirwa itsvo inoshanda membrane fluid, yegungwa desalination membrane fluid uye zvimwe zvinonyungudutsa zvinogadzirwa neindasitiri yemishonga.
