Kev soj ntsuam ntawm furfuryl cawv kev lag luam kev lag luam kev loj hlob zeem muag

Furfuryl cawv yog ib qho tseem ceeb organic chemical raw khoom.Feem ntau yog siv nyob rau hauv ntau yam khoom ntawm furan resin,furfuryl cawvurea formaldehyde resin thiab phenolic resin. Hydrogenation tuaj yeem tsim tetrahydrofurfuryl cawv, uas yog cov kuab tshuaj zoo rau cov kua roj vanish, pigment thiab foob pob hluav taws roj. Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv cov khoom siv hluavtaws, roj hmab, tshuaj tua kab thiab kev lag luam casting.

Furfuryl cawv tsis yog tsuas yog siv los ua cov khoom siv raw ntawm furan resin, tab sis kuj yog cov tshuaj zas, kua roj vanish, phenolic resin, hnyav lossis dispersant ntawm furan resin, wetting agent, thiab lwm yam.Qhov txias tsis kam ntawm plasticizer ua los ntawm nws zoo dua li ntawm butyl cawv thiab octanol esters.

Siv furfural raws li cov khoom siv raw tuaj yeem tsim cov khoom siv rov ua dua tshiab, xws li furfural resin ntau lawm thiab furfural hydrogenated khoom ntau lawm. Cov khoom hu ua furfural hydrogenated xa mus rau furfural nyob rau hauv tej yam kub, catalyst thiab pH nqi tej yam kev mob, tuaj yeem hnov ​​​​mob nrog hydrogen los tsim tetrahydrofuran, furfuran cawv thiab lwm yam tshuaj, kuj tseem tuaj yeem ua ntxiv condensation los tsim furan resin, dav siv hauv tshuab thiab kev lag luam tshuaj.

Furfuryl cawv, tseem hu ua furfuryl cawv, yog ib qho tseem ceeb organic chemical raw khoom. Nws cov khoom lag luam tau pom thawj zaug los ntawm Quaker Oats Company hauv xyoo 1948. Furfuryl cawv yog ib qho tseem ceeb derivative ntawm furfural, uas yog npaj los ntawm catalytic hydrogenation ntawm furfural nyob rau hauv roj los yog kua theem. Furfural tuaj yeem ua los ntawm kev tawg thiab dehydrating pentose los ntawm cov qoob loo pov tseg xws li pob kws cobs, sucrose residue, paj rwb husks, sunflower stalks, nplej husks thiab mov husks.

Furfuryl cawv yog cov khoom siv tseem ceeb ntawm furan resin. Nws cov khoom muaj xws li: urea-formaldehyde furan resin, phenolic furan resin, keto-aldehyde furan resin, urea-formaldehyde phenolic furan resin. Cov resin yog dav siv nyob rau hauv casting thiab core ua. Furfuryl cawv kuj tuaj yeem siv los ua cov tshuaj tua kab mob, cov khoom siv tshuaj.

Furfural cawv feem ntau yog siv rau hauv kev tsim cov furfural resin, furfuran resin, furfural cawv - cov zis aldehyde resin, phenolic resin, thiab lwm yam. Nws kuj yog siv los npaj cov txiv hmab txiv ntoo acid, plasticizer, hnyav thiab foob pob ua ntxaij roj. Tsis tas li ntawd, nyob rau hauv dyes, hluavtaws fibers, roj hmab, tshuaj tua kab, casting thiab lwm yam kev lag luam sectors kuj tau lug siv.
