Qeb roj teeb theem: Siv cov roj teeb lithium thiab lwm yam kev lag luam.
Muaj qeb Industrial: Siv tshuaj acetylene, butadiene extraction, cov tshuaj tua hluav taws xob, inks, cov pigments, kev lag luam tu thiab lwm yam kev lag luam.
Polymer Kev Lag Luam: NMP feem ntau siv raws li cov kuab tshuaj nyob hauv kev tsim cov noob polymers, resins, thiab cov fibers.
Kws tsim khoom: NMP yog siv hauv cov tshuaj ua lag luam, xws li cov tshuaj yeeb thiab hluavtaws.
Agochemicals: nws pom cov ntawv thov hauv kev tsim cov tshuaj tua kab thiab cov tshuaj tua kab.
Xim thiab pleev xim: NMP tuaj yeem siv los ua cov kuab tshuaj nyob rau hauv cov qauv ntawm cov xim tha xim, pleev xim, thiab inks.
Roj thiab roj: nws tau ua haujlwm nyob rau hauv extraction ntawm cov roj thiab roj, tshwj xeeb tshaj yog nyob rau hauv kev tshem tawm ntawm cov txiv lws suav.
Cov yam ntxwv tshwj xeeb:
Ncov npab polaric saftapent: nmp's polaric thiab apotic xwm ua rau nws zoo heev kuab tshuaj rau ntau yam ntawm cov ncej ncov qaum thiab tsis yog cov neeg tsis sib xws.
High boiling taw tes: nws cov kev tso cai npau npau tso cai rau nws siv hauv cov txheej txheem kub-uas tsis muaj kev tawm tsam sai.
Kev Nyab Xeeb thiab Kev Tswj Xyuas:
Yuav tsum ceev faj kev nyab xeeb yog tsim nyog thaum tuav NMP, suav nrog cov khoom siv thiab cov khoom tiv thaiv zoo, raws li nws tuaj yeem nqus tau ntawm daim tawv nqaij.
Kev tswj hwm kev ua li haujlwm, suav nrog kev ua haujlwm ntawm kev noj qab haus huv thiab kev nyab xeeb, yuav tsum tau ua raws.
