Methyl Nadic Anhydride (MNA) Chaw tsim tshuaj paus & tsum
Lub tshuab ua kua cycloaliphatic anhydride hardener ua rau ntawm lub pob txha pob txha pob txha tsis sib xws - xa cov khoom siv hluav taws xob zoo tshaj plaws, rwb thaiv tsev hluav taws xob zoo heev thiab kev coj tus cwj pwm laus hauv siab - kub epoxy casting, potting, lamination thiab aerospace composite systems.
Product Identification ntawm ib Glance
MNA yog dab tsi?
Methyl nadic anhydride (MNA) yog cycloaliphatic anhydride tsim los ntawm Diels-Alder cov tshuaj tiv thaiv ntawmcyclopentadiene nrog txiv neej anhydride, ua raws li methylation. Nws yog muab raws li ib tuglub teeb daj kuauas tseem ntws mus rau -15℃- sib txuas ua ke yooj yim ntawm cov kua methyl anhydrides nrog cov qauv uas ua rau lawv ua tau zoo ntawm qhov kub thiab txias.
Dab tsi ua rau MNA sib nrug yog nwsrigid bicyclic norbornene caj qaum. Qhov no compact, xauv-ntiv nplhaib architecture tsim high crosslink ceev nyob rau hauv kho epoxy tes hauj lwm, raising kub distortion kub thiab iav hloov (Tg) zoo tshaj qhov methyl-tetrahydrophthalic anhydrides ua tau. Qhov tshwm sim: kho tshuab nrogsiab kub tsis kam, zoo hluav taws xob rwb thaiv tsev thiab zoo heev aging cwj pwm- yog vim li cas MNA tau teev tseg rau hluav taws xob- qib laminates, siab-voltage rwb thaiv tsev thiab aerospace composite matrices.
Tshaj li epoxy, MNA ua haujlwm li areactive tsev thaivrau unsaturated polyester thiab alkyd resins, avulcanization regulator thiab adhesion txhawbnyob rau hauv cov roj hmab tebchaw, thiab ib tug tshuaj intermediate rau plasticizers, tshuaj tua kab thiab nplua - tshuaj synthesis.
