Cov ntawv thov hauv teb ntawm kev siv cov kuab tshuaj thiab txheej
Siab -} boiling - point solvents: ntsib qhov yuav tsum tau ua rau high- kub ua
AcetoYLACETON (2,5-hexanedione) yog qhov kev xaiv tseem ceeb hauv kev muaj cov kuab siv kuab lom vim nws lub siab bub (191-194 degree) thiab qis vapor siab. Lub xub ntiag ntawm ob pawg carbonyl (c {{4 4}}}}} O) nyob rau hauv nws cov qauv molececular tau txhim kho kom ruaj khov thiab tiv thaiv kev poob siab. Cov xeeb ceem no ua rau nws zoo nkauj hauv cov xwm txheej hauv qab no:
Tsheb Cov Duab Xim Thiab Muaj Tshuaj Txau
Hauv cov tsheb tsim, cov txheej yuav tsum tau ci ntawm qhov kub (feem ntau 150-200 degree) los kho. Cov sawv daws ib txwm muaj xws li toluene thiab xylene feem ntau tau txais kev cuam tshuam ntawm kev kub ntxhov, xws li pinholes nthab (xws li pinholes, txiv kab ntxwv tev) ntawm txheej. Txawm li cas los xij, acetonesylacetone lub siab npau npau ua kom ntseeg tau tias nws txuas ntxiv mus rau lub resin thaum lub sij hawm ci, ua rau muaj kev sib txawv thiab du txheej. Piv txwv li, ib qho kev siv cov khoom siv xim hauv ntiaj teb siv nws ua cov kuab tshuaj tsuag dej noo noo, cov huab cua tsis zoo ntawm cov txheej.
Ntim tshuab luam ntawv thiab cov number luam
Luam Ntawv Innks yuav tsum tau sai sai ntawm qhov kub (120-150 degree) kom haum siab siab- ceev luam ntawv presses. AcetYYLALACETON tuaj yeem ploj cov resins xws li polyamide thiab nitrocellulose, thaum nws cov txheej txheem qis dua thaum lub sijhawm ua kom yooj yim, tiv thaiv blrurring lossis tev ntawm cov qauv luam tawm. Lub ntim tshuab luam ntawv nce luam ntawv ceev los ntawm 20% thiab txo cov ntawv qhia tsawg los ntawm 15% los ntawm kev hloov cov kev sib dhos nrog acetonylacetone.
Xav tau tsav los ntawm ib puag ncig cov cai
Raws li kev txwv thoob ntiaj teb ntawm Voc emissions ua cov kev cai (xws li EU ncav cuag cov cai thiab cov qauv hauv Suav 33372}- boiling-point solvents tseem loj tuaj. AcetoYLACETONE muaj cov ntsiab lus qis dua li cov kev tswj hwm ib txwm muaj thiab muaj cov biodegradity, sib dhos nrog cov khoom ntsuab ntsuab. Piv txwv li, lub tuam txhab pleev xim kho nws cov qauv txhawm rau txhawm rau txhawm rau txhawm rau txhaj tshuaj 40%, txo cov khoom lag luam thiab ua tiav kev lag luam European.
Solubility ntawm cov xim Resins: Txhim Kho Kev Ua Tau Zoo thiab Kev Ruaj Ntseg
Acetonylacetone's solubility nyob rau ntau lub resins ua rau nws qhov tseem ceeb ntawm cov xim tsim. Nws cov tshuab ntawm kev nqis tes ua xws li:
Polarity matching thiab hydrogen tsev
CarboronyL pab pawg (c=} o) hauv nws cov molecule tuaj yeem tsim cov pab pawg polar nyob rau hauv cov pawg rasin (xws li cov pawg hydroxyl thiab cov solubility. Piv txwv li, hauv Alkyd Resin Txheej, Acetonesylacetone tuaj yeem tsoo cov tshuab roj hmab hauv cov mis thiab txhim kho lub harterness thiab tshuaj lom neeg tiv thaiv cov txheej.
Cov txiaj ntsig zoo hauv kev ua kom muaj txiaj ntsig zoo
Piv rau cov kuab tshuaj hydrocarbon, acetonylacetone muaj kev sib zog zoo dua rau cov resins zoo li rosin thiab shellac. Ib txheej ntoo txheej txheem ua lag luam nce cov solubility ua haujlwm ntawm Rosin cob los ntawm kev ntxiv lub sijhawm kom qhuav ntawm 30% thiab txhim kho cov kab no los ntawm 20%.
Yooj yooj yim hauv cov txiaj ntsig tshwj xeeb
Rau qhov nyuaj - rau -}} waxed} Cov pos hniav Dramal, ua tiav cov kev sib cais ib nrab, tsim cov kev sib cais ib nrab. Cov xeeb ceem no ua rau nws cov ntawv thov hauv cov tshuaj pleev xim ua piv thiab tshwj xeeb txheej txheem. Piv txwv li, ib qho kev ua kom qub thaum ub tau hloov kho cov kev ua kom haum ntawm cov pos hniav ntawm cov teeb meem ib txwm muaj thaum ua kom tiav durabiling.
Tawv ntawm tawv: Txhim Kho Cov Khoom Siv Lub Cev
Hauv kev ua tawv tawv, acetonesylacetone yog siv los ua tus neeg sawv cev tann, txhim kho tawv tawv zoo los ntawm cov ntoo khaublig nrog nrog collagen:
Hla - ntawv txuas ib mechanism thiab kev ua tau zoo txhim kho
Cov pab pawg carboryL hauv nws cov lwg tuaj yeem tsim kev sib tsoo nrog cov amino pab pawg hauv cov tawv nqaij tawv, txhim kho txoj kev sib raug zoo ntawm cov fibers. Cov ntaub ntawv sim qhia tau tias tawv kho nrog acetylacetone muaj lub tensile lub zog nce los ntawm 15}}}}}}}}}}} Lub siab-kawg tawv hom txhim kho tus txheej txheem tanning los ntawm kev ua kom zoo dua ntawm acetony
Kev tiv thaiv ib puag ncig thiab kev them nqi zoo
Piv rau cov tsoos chromium tanning cov neeg sawv cev, acetonylacetone tsis muaj cov pa phem hnyav thiab ua luv luv ntawm 20%. Siv cov tawv nqaij cov kws ua lag luam, dhau ntawm {2} Ntau lawm ntau lawm, txo qis tus nqi sib tw nyob rau hauv nruab nrab {4 5}}} Thok tev ua lag luam
Cov qauv kev lag luam thiab cov nyom
Thov kev loj hlob thiab thaj chaw sib txawv
Nrog rau kev txhim kho sai sai ntawm kev lag luam tsheb thiab ntim ntim hauv Asia - pacific cheeb tsam, qhov kev thov rau acetylacetone tseem loj hlob. Nws cia siab tias kev lag luam thoob ntiaj teb yuav ntau dua 200 lab daus las los ntawm 2027, nrog rau cov lej sib xyaw ntawm cov neeg hauv 5,2%. Ntawm lawv, kev lag luam tawm xws li Tuam Tshoj thiab Is Nrias teb yuav muaj kev loj hlob tus nqi ntau dua li qhov nruab nrab ntiaj teb vim kev tiv thaiv ib puag ncig.
Kev thaiv kev lag luam thiab kev hloov pauv
Although Acetonylacetone has excellent performance, its synthesis process is complex (such as the 2,5-dimethylfuran hydrolysis method has a higher cost), resulting in significant price fluctuations. Tsis tas li ntawd, sawv ntawm bio - raws cov kuab tshuaj (xws li lactate estre) yuav ua rau muaj kev hem thawj) yuav ua rau nws muaj kev hem thawj. Kev nkag mus yuav tsum tau txo tus nqi los ntawm kev siv innixatical thiab tsim kom muaj nuj nqis ntxiv) los ua cov khoom siv hluav taws xob) los sib sau ua ke.
