Vagadziri vakanaka mutengo n-methyl pyrrolidone (NMP) CAS: 872-50-4 fan akafananidzirwa mufananidzo

Tsananguro pfupi:

N-methyl Pyrrodidone inotaurwa nezveNMP, molecular formula: acetone uye dzakasiyana-siyana organic sol sol soles, halogenated hydrocarbons, anamatic Hydrocarbons, dzinenge dzinosanganiswa zvachose nemamwe mashiripiti 204 ℃, Flash Pfungwa 91 NMP ine zvakanakira viscosity yakaderera, yakagadzikana yemakemikari yakaderera uye kugadzikana kwekunyora, polarity, yakaderera, uye isingaenzaniswi nemvura nemvura uye yakawanda organic sol sol. NMP idyo-zvinodhaka, uye zvinobvumidzwa muganho wekusangana mumhepo ndeye 100ppm.

Zvikumbiro zveNMP

N-methylpyrrolidone (NMP) iri polar aprotic solvent. Iyo ine yakaderera utsi, yakakwira boling point uye yakasarudzika solubility. Zvakanakira sarudzo dzakasimba uye kugadzikana kwakanaka. Inoshandiswa zvakanyanya muHyomatic hydrocarbon yekubvisa, kucheneswa kweAcety yePolyinjini mapurasitiki, ekurima emarobhoti, kusimbisa kwedunhu kugadzirwa, kuchenesa kwemaitiro ekupora kwesi, pvc inowedzera, etc. inoshandiswawo solvent ye polymers uye a Pakati pei polymerization, yakadai seinjiniya mapurasitiki uye marara emarwi. Inogona zvakare kushandiswa mumishonga yekuuraya zvipuka, mishonga uye yekuchenesa vamiririri. Iko kushandiswa kukuru kwemakiredhi akasiyana eN-methylpyrrolidone kwakanyorwa pazasi:

1. Maindasitiri echiindasitiri: Lubricat Ory Kunatsiridza, Lubricating Oinel Forredelides, magetsi ekurima, PVC. muenzaniso, inoshandiswa kuburitsa hydrocarbons mukati Lubricating mafuta kuzadzisa chinangwa chekunatsa mafuta anodzvinyirira; Nekuda kwekukakavara kweNMP kuResin, inogona kushandiswa solvent yeresin uye kurongedza, kuumbwa-kuumba, kuumbwa kwechikamu chakagadzirwa nenhamba yekuchengetera zvinhu zvekushandisa, fiber machira uye anomamatira uye zvimwe zvigadzirwa.

2.. uye kuchena kwekudzoreredza kwakaomeswa acetylene kunogona kusvika 99.7%; Semunhu anodzora ekuparadzanisa uye kudzoreredza yakakwira-yekuchenesa butadiene kubva kuC4 hydrocarbons, chiyero chekupora chinogona kusvika 97%. %. Kana ichishandiswa seinodzungaira yehunhu hydrocarbons, ine yakakwirira solubility yeanonhuhwirira hydrocarbons. Nemawere epasi kumanikidzwa, chiyero chekurasikirwa cheweturu chakaderera uye huwandu hwekudzora hwevanyepedzere zvakakwirira.

3 , PCB yakadhindwa mapuranga wedunhu, disks yakaoma; uye solventes yakagadzirwa muindasitiri yemishonga yakadai seyenyendi yekunyepa
