Zoo heev lub teeb ceev ceev
Kev txiav txim siab pom zoo pom zoo ntawm cov khoom siv syntan
Muaj ib txwm muaj qee qhov classic uas peb pom hauv peb lub neej uas ua rau peb luag txhua zaus peb xav txog lawv. Zoo li cov khau tawv tawv tawv zoo nkauj zoo nkauj hauv koj lub txee khau.
Txawm li cas los xij, qee zaum nws ua rau koj nco qab tias dhau sijhawm, koj cov khau nyiam khau yuav tsis zoo li dawb thiab ci, thiab maj mam dhau los ua xim daj.
Tam sim no cia peb pom dab tsi tom qab ntawm yellowing ntawm tawv dawb —
Xyoo 1911 AD Dr. Stiasny tau tsim ib qho tshiab hluavtaws tannin uas tuaj yeem hloov cov zaub tannin. Nyob rau hauv kev sib piv nrog zaub tannin, hluavtaws tannin yog ib qho yooj yim los tsim, muaj zoo tanning khoom, lub teeb xim thiab zoo penetrability. Yog li nws tau los tuav txoj haujlwm tseem ceeb hauv kev lag luam tanning ntau pua xyoo ntawm txoj kev loj hlob. Nyob rau hauv niaj hnub tanning technology, hom hluavtaws tannin no yog siv nyob rau hauv yuav luag tag nrho cov khoom.
Vim nws cov qauv sib txawv thiab daim ntawv thov, lawv feem ntau hu ua hluavtaws tannin, phenolic tannin, sulfonic tannin, disperse tannin, thiab lwm yam. Qhov sib txawv ntawm cov tannins 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 UV rays, nws tsim cov xim rendering qauv uas tig cov tawv daj: Cov qauv phenol tau yooj yim oxidized rau hauv quinone lossis p-quinone xim-rendering qauv, uas yog vim li cas. nws lub teeb fastness kuj tsis zoo.
Muab piv rau hluavtaws tannin, polymer tannin tus neeg saib xyuas thiab cov amino resin tanning tus neeg saib xyuas muaj cov khoom zoo dua los tiv thaiv daj, yog li kev kho tawv nqaij, hluavtaws tannins tau dhau los ua qhov tsis muaj zog rau kev tiv thaiv daj.
Txhawm rau daws qhov teeb meem no, Kev Txiav Txim Siab Pab Pawg R & D tau ua qee qhov kev ua kom zoo ntawm cov qauv phenolic los ntawm kev xav thiab tsim, thiab thaum kawg tsim cov khoom siv hluavtaws tshiab nrog lub teeb nrawm nrawm:
DESOATEN SPS
Syntan nrog lub teeb nrawm nrawm
Muab piv rau cov pa syntans, cov khoom tiv thaiv daj ntawm DESOATEN SPS tau ua ib qho tseem ceeb leap -
Txawm tias sib piv nrog cov pa roj carbon monoxide tanning tus neeg saib xyuas thiab cov amino resin tanning tus neeg saib xyuas, DESOATEN SPS muaj peev xwm ua rau lawv tawm ntawm qee yam.
Los ntawm kev siv DESOATEN SPS ua lub ntsiab hluavtaws tannin, ua ke nrog lwm cov tanning tus neeg sawv cev thiab fatliquors, zus tau tej cov tawv tawv thiab kuj dawb tawv nrog zoo heev lub teeb ceev yuav ua tau tiav.
Yog li mus tom ntej thiab hnav koj cov khau tawv dawb nyiam ntau npaum li koj nyiam, mus ntawm lub puam thiab da dej hauv tshav ntuj, tsis muaj dab tsi tuaj yeem txwv koj tam sim no!
Kev loj hlob ruaj khov tau dhau los ua ib feem tseem ceeb hauv kev lag luam tawv, txoj hauv kev rau kev txhim kho kom ruaj khov tseem ntev thiab muaj kev sib tw.
Raws li lub luag haujlwm ua lag luam peb yuav nqa qhov no raws li peb lub luag haujlwm thiab ua haujlwm tsis tu ncua thiab indomitably mus rau lub hom phiaj kawg.
