Kufotokozera
N-Methyl-2-pyrrolidone ndi mankhwala osungunulira aprotic omwe amagwiritsidwa ntchito m'njira zosiyanasiyana: kukonza petrochemical, kuphimba pamwamba, utoto ndi zinthu zina, mankhwala oyeretsera m'mafakitale ndi m'nyumba, komanso mankhwala a zaulimi ndi mankhwala. Ndi mankhwala okwiyitsa, komanso amayambitsa matenda angapo a contact dermatitis m'kampani kakang'ono ka zamagetsi.

Kagwiritsidwe Ntchito
Ntchito
N-Methyl-2-pyrrolidone (NMP) ndi chosungunulira cha polar aprotic chomwe chili ndi ubwino wa poizoni wochepa, kutentha kwambiri, kulimba kwabwino, kusankha bwino komanso kukhazikika bwino.
Amagwiritsidwa ntchito kwambiri poyeretsa mafuta onunkhira a hydrocarbon, acetylene, olefins, ndi diolefins.
Amagwiritsidwa ntchito poyeretsa mafakitale, ndipo amagwiritsidwa ntchito ngati chosungunulira popanga mankhwala ophera tizilombo, mapulasitiki aukadaulo, zokutira, ulusi wopangidwa, ndi ma circuits ophatikizidwa.
Ingagwiritsidwenso ntchito ngati chotsukira cha mafakitale, chosungunula zinthu, utoto, mafuta odzola komanso choletsa kuzizira.
N-Methyl-2-pyrrolidone ndi chosungunulira chabwino kwambiri, chomwe chimagwiritsidwa ntchito kwambiri pochotsa mafuta onunkhira, kuyeretsa mafuta, kuwonjezera acetylene, kulekanitsa butadiene ndi kupanga mpweya wochotsa sulfur.
Amagwiritsidwa ntchito pochotsa mpweya woipa, kuyeretsa mafuta, kuyeretsa mafuta oletsa kuzizira, kuchotsa olefin, komanso ngati chosungunulira cha polymerization ya pulasitiki yaukadaulo yosasungunuka.
Itha kugwiritsidwa ntchito mu mankhwala ophera tizilombo, kuyeretsa zipangizo zotetezera kutentha, zida zolondola zamakampani opanga zinthu zosiyanasiyana ndi ma circuit board, kubwezeretsanso utsi wa PVC, ngati sopo, chowonjezera utoto ndi chofalitsira.
Amagwiritsidwa ntchito m'njira zopangira ma polymerization monga mapulasitiki aukadaulo ndi ulusi wa aramid.
N-Methyl-2-pyrrolidone imagwiritsidwa ntchito ngati polyvinylidene fluoride solvent komanso ngati chinthu chothandizira ma electrode pamabatire a lithiamu ion.
kalasi yapamwamba kwambiri yoyezera ICP-MS.
Kuti apange peptide.
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.
