Furfuyl cawv thiab Foundry tshuaj

Peb lub tuam txhab koom tes nrog East China University of Science thiab Technology, thiab thawj zaug txais cov tshuaj tiv thaiv tsis tu ncua nyob rau hauv lub hwj thiab Nruam distillation txheej txheem rau kev tsim khoom.Furfuryl cawv. Tag nrho pom cov tshuaj tiv thaiv ntawm qhov kub thiab txias tsis siv neeg cov chaw taws teeb tswj, ua kom zoo dua ruaj khov thiab cov nqi tsim khoom qis dua. Peb muaj cov khoom lag luam zoo rau cov khoom siv casting, thiab ua tau zoo hauv cov txheej txheem thiab ntau yam khoom. Cov khoom tshwj xeeb ua rau kev txiav txim kuj muaj raws li qhov kev thov los ntawm cov neeg siv khoom. Peb muaj cov kws tshaj lij pab pawg txaus siab rau lub koob npe nrov hauv kev lag luam rau kev tsim khoom, kev tshawb fawb thiab kev pabcuam, uas tuaj yeem daws koj cov teeb meem casting raws sijhawm.

Furfuryl cawv

CAS : 98-00-0 Molecular formula: C₅H₆O2₂Molecular Luj: 98.1

Lub cev muaj zog:Lub teeb daj flammable kua nrog iab almond tsw, nws yuav tig xim av los yog sib sib zog nqus liab thaum raug tshav ntuj los yog huab cua. Nws yog miscible nrog dej, insoluble hauv petroleum hydrocarbons. Nws yog ib qho yooj yim rau polymerize thiab hnov ​​​​mob hnyav nyob rau hauv cov ntaub ntawv ntawm acid, tsim resin uas tsis yaj.

Daim ntawv thov:Raws li ib qho ntawm cov khoom siv raw rau cov organic synthesis, nws tuaj yeem siv los tsim levulinic acid, furan resin nrog ntau yam khoom, furfuryl cawv-urea resin thiab phenolic resin. Qhov txias tsis kam ntawm cov yas ua los ntawm nws yog zoo dua li ntawm Butanol thiab Octanol esters. Nws kuj yog cov kuab tshuaj zoo rau furan resins, varnishes, thiab pigments, thiab foob pob hluav taws roj. Tsis tas li ntawd, nws kuj tseem siv rau hauv cov khoom siv hluavtaws, roj hmab, tshuaj tua kab thiab kev lag luam foundry.

Ntim thiab khaws cia:

Ntim hauv lub nruas hlau nrog qhov hnyav ntawm 240kg. 19.2 tons (80 nruas) hauv 20FCL .Los yog 21-25 tons hauv ISO TANK lossis ntau. Khaws rau hauv qhov chaw txias, qhuav, ventilated. Tinder yog txwv tsis pub. Tsis txhob khaws cov kua qaub uas muaj zog, oxidizing tshuaj thiab zaub mov.
