QAUV:
Cawv Furfuryl yog cov kua organic ntshiab tsis muaj xim uas muaj furan hloov nrog pawg hydroxymethyl. Nws yog siv rau kev tsim cov furans resins uas siv rau hauv thermoset polymer matrix composites, cements, nplaum thiab coatings. Nws ua lub luag haujlwm tseem ceeb hauv kev tsim cov xuab zeb foundry thiab tau siv ntev los tsim cov cores thiab pwm rau kev casting hlau. Lwm cov ntawv thov suav nrog ua roj thiab kev kho ntoo. Hauv kev lag luam, nws yog tsim los ntawm kev txo qis ncaj qha ntawm furfural, lossis los ntawm kev tsis sib npaug ntawm Cannizaro reaction hauv NaOH kua. Cov khoom siv raw rau nws cov khoom tsim yog cov khoom pov tseg zaub xws li cov plhaub mov, qab zib bagasse, oat hulls lossis corncobs.

Kev Siv
Cov kua tsis muaj xim uas hloov xim tsaus ntuj hauv huab cua
Furfuryl Cawv tau txais los ntawm kev txo cov poov xab ntawm furfural. Furfuryl Cawv yog siv ua cov kuab tshuaj thiab hauv kev tsim cov neeg sawv cev ntub dej, cov resins.
Cov kuab tshuaj; kev tsim cov neeg sawv cev ntub dej, cov resins.
Ntim Khoom
250KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
