Cov Lus Qhia Txog Kev daws teeb meem
Kev ruaj khov zoo heev
Kev txiav txim siab qhov kev pom zoo zoo tshaj plaws ntawm cov khoom syntan
Yeej ib txwm muaj tej yam khoom qub uas peb pom hauv peb lub neej uas ua rau peb luag ntxhi txhua zaus peb xav txog lawv. Zoo li cov khau tawv dawb uas xis nyob hauv koj lub txee khau.
Txawm li cas los xij, nws qee zaum ua rau koj txhawj xeeb thaum koj nco ntsoov tias dhau sijhawm, koj cov khau nyiam yuav tsis dawb thiab ci ntsa iab lawm, thiab yuav maj mam laus thiab daj.
Tam sim no cia peb nrhiav seb dab tsi yog tom qab ntawm qhov daj ntawm tawv dawb——
Xyoo 1911 AD, Dr. Stiasny tau tsim ib hom tannin tshiab uas hloov tau cov tannin los ntawm zaub. Piv rau cov tannin los ntawm zaub, cov tannin yooj yim tsim, muaj cov khoom zoo heev rau kev tanning, xim kaj thiab nkag tau zoo. Yog li ntawd, nws tau los ua ib qho tseem ceeb hauv kev lag luam tanning dhau ib puas xyoo ntawm kev txhim kho. Hauv cov thev naus laus zis niaj hnub no, hom tannin no siv rau hauv yuav luag txhua yam khoom.
Vim nws cov qauv sib txawv thiab daim ntawv thov, lawv feem ntau hu ua synthetic tannin, phenolic tannin, sulfonic tannin, disperse tannin, thiab lwm yam. Qhov sib xws ntawm cov tannins no yog tias lawv cov monomer feem ntau yog cov qauv tshuaj phenolic.
Txawm li cas los xij, thaum cov qauv phenolic raug tshav ntuj, tshwj xeeb tshaj yog rau cov duab UV, nws tsim cov qauv xim uas hloov cov tawv nqaij daj: Cov qauv phenol yooj yim oxidized rau hauv quinone lossis p-quinone xim-rendering qauv, yog vim li cas nws lub teeb ceev tsis zoo.
Piv rau cov tannin hluavtaws, cov neeg sawv cev polymer tannin thiab cov neeg sawv cev amino resin tanning muaj cov khoom tiv thaiv daj zoo dua, yog li rau kev kho tawv nqaij, cov tannins hluavtaws tau dhau los ua qhov txuas tsis muaj zog rau kev ua haujlwm tiv thaiv daj.
Yuav kom daws tau qhov teeb meem no, pab pawg R&D ntawm Decision tau ua qee qhov kev txhim kho ntawm cov qauv phenolic los ntawm kev xav tshiab thiab kev tsim qauv, thiab thaum kawg tau tsim cov tannin tshiab nrog lub teeb ci zoo heev:
DESOATEN SPS
Syntan nrog lub teeb ci ntsa iab zoo heev
Piv rau cov syntans ib txwm muaj, cov khoom tiv thaiv kev daj ntawm DESOATEN SPS tau ua tiav qhov kev dhia tseem ceeb -
Txawm tias piv nrog cov neeg sawv cev polymer tanning thiab cov neeg sawv cev amino resin tanning, DESOATEN SPS muaj peev xwm ua tau zoo dua lawv hauv qee yam.
Los ntawm kev siv DESOATEN SPS ua cov tannin tseem ceeb, ua ke nrog lwm tus neeg sawv cev tanning thiab cov rog, kev tsim cov tawv nqaij dav dav thiab cov tawv dawb nrog lub teeb ci zoo heev tuaj yeem ua tiav.
Yog li ntawd, mus tom ntej thiab hnav koj cov khau tawv dawb nyiam npaum li koj nyiam, mus ntawm ntug hiav txwv thiab da dej hauv lub hnub ci, tsis muaj dab tsi tuaj yeem nres koj tam sim no!
Kev txhim kho kom ruaj khov tau dhau los ua ib feem tseem ceeb heev hauv kev lag luam tawv, txoj kev mus rau kev txhim kho kom ruaj khov tseem ntev thiab muaj ntau yam kev cov nyom.
Ua ib lub tuam txhab uas muaj lub luag haujlwm, peb yuav ua qhov no ua peb lub luag haujlwm thiab ua haujlwm tas li thiab tsis muaj zog mus rau lub hom phiaj kawg.
