Trimethylolpropane (luv ua TMP)

Trimethylolpropane (TMP) yog ib yam khoom siv tshuaj lom neeg tseem ceeb uas muaj kev siv dav dav, xws li alkyd resins, polyurethanes, unsaturated resins, polyester resins, thiab coatings. Tsis tas li ntawd, TMP siv rau hauv kev tsim cov roj nplua nyeem rau kev tsav dav hlau, cov kua luam ntawv, thiab ua haujlwm ua cov khoom siv textile thiab thermal stabilizer rau polyvinyl chloride (PVC) resins.

Ua ib qho khoom siv dav dav hauv kev lag luam resin, TMP yog ib yam khoom tseem ceeb uas tsav tsheb kev txhim kho kev lag luam ntawm polyols sector. Nws cov qauv molecular tshwj xeeb ua rau nws muaj qhov melting point qis thiab glycerol zoo li polyol yam ntxwv. TMP tsis yog tsuas yog hloov glycerol hauv kev tsim cov alkyd resins tab sis kuj sib koom ua ke nrog lwm cov polyols xws li neopentyl glycol thiab pentaerythritol, ntxiv rau ntau hom alkyd resins. Qhov kev hloov pauv no ua rau muaj kev ua tau zoo thiab kev hloov pauv ntawm cov khoom siv resin, ua kom TMP lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom siv tshiab thiab kev siv tau zoo thoob plaws hauv kev lag luam.

Cov alkyd resins uas siv TMP ua tau zoo heev rau kev tiv thaiv hydrolysis, kev ruaj khov ntawm oxidation, kev tiv thaiv alkali, thiab kev ruaj khov ntawm thermal, ua rau lawv zoo heev rau kev tsim cov xim cim txoj kev. Lawv kuj siv dav hauv kev tsim cov xim pleev xim rau tsheb, tub yees, tshuab ntxhua khaub ncaws, thiab lwm yam khoom siv hauv tsev. Ntxiv mus, TMP ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tsim cov surfactants, cov neeg sawv cev ntub dej, cov khoom tawg, cov khoom siv yas, cov yas fiberglass-reinforced, rosin esters, cov roj nplua nyeem dav hlau zoo, cov neeg sawv cev ua fiber, cov kua luam ntawv, thiab cov ua npuas polyurethane, ua haujlwm ua cov khoom siv txuas ntxiv rau cov saw hlau, cov khoom siv textile, thiab cov khoom siv thermal stabilizer rau PVC resins.

Cov khoom siv ntawm TMP pom muaj ntau daim ntawv thov thoob plaws ntau qhov chaw, ua haujlwm ua cov neeg sawv cev sib txuas, cov neeg sawv cev kho, cov emulsifiers, cov neeg sawv cev tso tawm, thiab cov catalysts. Lawv kuj siv rau hauv kev tsim cov kua membrane electrodes nrog kev xaiv siab rau sodium ions.

TMP feem ntau yog siv ua cov khoom siv raw rau kev tsim cov neeg sawv cev PU curing, synthesizing UV coatings, thiab tsim cov alkyd resins zoo. Hauv Suav teb, nws cov kev siv suav txog ntau dua 70% ntawm tag nrho cov kev siv hauv tsev ntawm trimethylolpropane. Tsis tas li ntawd, TMP ua lub luag haujlwm tseem ceeb hauv kev tsim cov polyester resins thiab titanium dioxide.

TMP tuav lub luag haujlwm tseem ceeb hauv kev tsim cov alkyd resins zoo, uas feem ntau siv rau hauv cov xim tsheb zoo tshaj plaws thiab cov neeg sawv cev photo-curing rau cov xim thiab inks. Raws li qhov zoo ntawm cov khoom hauv Suav teb cov tsheb thiab cov khoom siv hauv tsev txuas ntxiv zoo dua, qhov kev thov rau cov txheej txheem zoo tau nce siab heev. Tib lub sijhawm, cov kev cai ib puag ncig nruj dua tau tsav kev loj hlob ntawm kev thov rau cov neeg sawv cev photo-curing. Yog li ntawd, qhov kev thov rau TMP yuav muaj kev loj hlob ntau hauv xyoo tom ntej.
