Txhua txoj kev mus rau 'formaldehyde-dawb' ntiaj teb |Kev pom zoo ntawm kev txiav txim siab cov amino resin series khoom
Qhov cuam tshuam los ntawm cov dawb formaldehyde tsim thaum lub sij hawm tanning txheej txheem tau hais los ntawm tanneries thiab cov neeg siv ntau tshaj kaum xyoo dhau los.Txawm li cas los xij tsuas yog nyob rau xyoo tas los no qhov teeb meem tau raug coj los ntawm cov neeg ua luam dej.
Rau ob qho tib si loj thiab me tanneries, tsom tau hloov mus rau qhov kev sim ntawm cov ntsiab lus dawb formaldehyde.Qee cov tanneries yuav sim txhua pawg ntawm lawv cov tawv tshiab tsim los xyuas kom meej tias lawv cov khoom ua tau raws li cov qauv.
Rau cov neeg feem coob hauv kev lag luam tawv, kev paub txog yuav ua li cas txo cov ntsiab lus ntawm cov dawb formaldehyde hauv tawv tau ua kom pom tseeb -

Qhia kom txhob ntseeg yuam kev |Kev txiav txim siab qhov kev pom zoo ntawm cov kws tshaj lij kev pabcuam ua haujlwm
Surfactants yog cov txheej txheem nyuaj, txawm hais tias lawv tuaj yeem raug hu ua surfactants, lawv cov kev siv tshwj xeeb thiab daim ntawv thov yuav txawv kiag li.Piv txwv li, thaum lub sij hawm tanning txheej txheem, surfactants yuav siv tau raws li tus neeg sawv cev nkag mus, theem tus neeg sawv cev, wetting rov qab, degreasing, fatliquoring, retanning, emulsifying los yog bleaching khoom.
Txawm li cas los xij, thaum ob tus surfactants muaj qhov cuam tshuam zoo ib yam lossis zoo sib xws, yuav muaj qee qhov tsis meej pem.
Soaking tus neeg saib xyuas thiab degreasing tus neeg saib xyuas yog ob yam khoom siv surfactant uas feem ntau siv thaum lub sij hawm ntub dej.Vim tias qee qhov kev ntxuav thiab ntub dej muaj peev xwm ntawm surfactants, qee lub chaw tsim khoom yuav siv nws ua cov khoom ntxuav thiab ntub dej.Txawm li cas los xij, kev siv tshwj xeeb ionic soaking tus neeg sawv cev yog qhov tseem ceeb thiab tsis tuaj yeem hloov pauv.

Polymer tanning tus neeg saib xyuas nrog Ultra kev ua tau zoo thiab 'Unique' molecular hnyav |Kev txiav txim siab cov khoom pom zoo pom zoo
polymer khoom molecular hnyav
Hauv cov tshuaj tawv nqaij, ib qho ntawm cov lus nug uas txhawj xeeb tshaj plaws hauv kev sib tham ntawm cov khoom siv polymer yog tias, huab cua cov khoom yog micro lossis macro-molecule khoom.
Vim hais tias ntawm cov khoom polymer, qhov hnyav molecular (yuav tsum tau meej, qhov nruab nrab molecular hnyav. ib yam khoom polymer muaj micro thiab macro-molecule Cheebtsam, yog li thaum hais txog qhov hnyav molecular, nws feem ntau yog hais txog qhov nruab nrab molecular hnyav.) Lub hauv paus ntsiab lus ntawm cov khoom lag luam, nws tuaj yeem cuam tshuam rau cov khoom ntim, nkag mus rau cov cuab yeej zoo li qhov muag muag thiab muag muag ntawm cov tawv tawv nws tuaj yeem muaj txiaj ntsig.Tau kawg, cov cuab yeej kawg ntawm cov khoom lag luam polymer muaj feem xyuam nrog ntau yam xws li polymerization, saw ntev, cov qauv tshuaj, kev ua haujlwm, pawg hydrophilic, thiab lwm yam. Qhov hnyav molecular tsis tuaj yeem suav tias yog ib qho kev siv ntawm cov khoom vaj khoom tsev.
Qhov hnyav molecular ntawm feem ntau ntawm cov polymer retanning cov neeg ua hauj lwm nyob rau hauv lub lag luam yog nyob ib ncig ntawm 20000 mus rau 100000 g / mol, cov khoom ntawm cov khoom nrog molecular hnyav nyob rau hauv lub caij no qhia tau hais tias muaj ntau yam khoom.Txawm li cas los xij, qhov hnyav molecular ntawm ob qho kev txiav txim siab cov khoom yog sab nraud ntawm lub sijhawm no nyob rau hauv qhov kev coj ua.

Zoo heev lub teeb 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.
