Vim li cas peb yuav tsum tiv thaiv kab lis kev cai relics?
Kev khaws cia ntawm kab lis kev cai relics yog ib qho tseem ceeb heev niaj hnub no. Tuam Tshoj yog ib lub teb chaws qub nrog keeb kwm yav dhau los thiab kev vam meej, thiab nws cov cuab yeej cuab tam kab lis kev cai muaj ntau haiv neeg, muaj ntau thiab nthuav dav. Cov cuab yeej cuab tam tseem ceeb no yog cov khoom siv ntawm cov ntaub ntawv ntawm kev vam meej thaum ub, cov ntaub ntawv tseem ceeb hauv keeb kwm, kab lis kev cai, kos duab thiab kev tshawb fawb, kev siv thiab qhov chaw ntawm kev tshawb fawb thiab kev tsim kho thev naus laus zis, thiab cov peev txheej tseem ceeb rau kev txhim kho cov khoom siv thiab sab ntsuj plig. kev ua neej nyob ntawm noob neej.
Dab tsi yog qhov cuam tshuam thiab qhov zoo ntawm organosilicon ntawm kev txuag cuab yeej cuab tam?
Vim tias cov khoom siv silicone muaj kev ruaj ntseg rau lub zog; Nws cov khoom siv tshuaj yog nyob nruab nrab ntawm cov organic thiab inorganic, muaj huab cua zoo, tiv thaiv tshav kub, stain tsis kam, tshuaj tiv thaiv, dej thiab nplaim hluav taws, muaj kev ruaj ntseg zoo rau ultraviolet rays, ozone, piv nrog rau lwm cov ntaub ntawv zoo heev "ua pa", nws tsis kev puas tsuaj los yog qhov tseem ceeb tsis ua rau lub permeability ntawm kab lis kev cai relics rau huab cua thiab dej vapor.
Kev siv cov khoom siv kho tshuab silicon hauv kev tiv thaiv kab lis kev cai
Lub unearthed kab lis kev cai relics yuav roughly muab faib ua peb pawg raws li lawv cov kev ntxhib los mos: inorganic kab lis kev cai relics (xws li pob zeb kab lis kev cai relics, ntiaj teb kab lis kev cai relics, pottery, cib thiab pobzeb khoom thiab hlau khoom) Organic kab lis kev cai relics (silk, ntawv, ntoo, tawv. cov khoom, thiab lwm yam) Composite kab lis kev cai relics (paintings, av nplaum sculptures, thiab lwm yam)
Cia peb tham hnub no.
Daim ntawv thov ntawm organosilicon hauv kev tiv thaiv pob zeb kab lis kev cai relics
Nta: Cov txheej txheem huab cua ntawm pob zeb kab lis kev cai relics yog complex, nrog rau lub cev, tshuaj, lom thiab tib neeg cov teebmeem. Txoj kev: Raws li cov yam ntxwv ntawm cov pob zeb kab lis kev cai relics thiab ua rau huab cua thiab hloov pauv, txoj kev ntawm txheej txheej tiv thaiv zaj duab xis ntawm nws nto tau txais yuav hauv tsev thiab txawv teb chaws los tiv thaiv cov ntaub ntawv pob zeb. Feem ntau tsim epoxy resins, acrylic resins, silicone cov ntaub ntawv thiab ntau yam khoom siv inorganic. Ntawm lawv, cov khoom siv silicone muaj qhov tseem ceeb tshaj plaws, thiab nws cov qauv zoo ib yam li cov qauv ntawm cov pob zeb kab lis kev cai relics ntxiv rau cov yam ntxwv ntawm cov khoom siv polymer.
Kev cuam tshuam ntawm hydrophobicity ntawm organosilicon ntawm kev txuag ntawm kab lis kev cai relics
Cov tshuaj tiv thaiv hydrophobic nyob rau saum npoo ntawm cov pob zeb loj loj tuaj yeem ua rau muaj kev puas tsuaj loj thaum qhov tob tob ntawm tus neeg tiv thaiv tsuas yog ob peb millimeters. Qhov me me ntawm lub zog ntawm lub pob zeb, qhov siab dua qhov nqus dej, qhov yooj yim dua puas tsuaj; Qhov muaj zog ntawm hydrophobicity ntawm tus neeg saib xyuas kev tiv thaiv, qhov ntau concentrated lub interfacial kev ntxhov siab, qhov ceev ntawm kev puas tsuaj yuav yog. Lub ntsiab yog vim li cas rau qhov kev puas tsuaj yog qhov sib txawv ntawm lub cev muaj zog ntawm lub hydrophobicity ntawm qhov chaw tiv thaiv thiab hydrophilicity ntawm lub pob zeb substrate thaum lub sij hawm ntub thiab qhuav txheej txheem thiab kev sib tshuam kev ntxhov siab. Salt crystallization, cua sov, khov-thaw yuav ua rau muaj kev puas tsuaj ntawm cov txheej txheem tiv thaiv saum npoo los ntawm cov txheej txheem ntawm cov dej tsiv teb tsaws thiab theem hloov hauv cov pob zeb, uas cov ntsev crystallization muaj txiaj ntsig zoo tshaj plaws, ua raws li cua sov thiab khov-thaw.
Yog li ntawd, peb yuav tsum ua tib zoo siv hydrophobic nto tshuaj tiv thaiv nyob rau hauv kev tiv thaiv ntawm pob zeb kab lis kev cai relics. Thaum nws yuav tsum tau siv, nws yuav tsum tau muab sau tseg tias kev tsiv teb tsaws thiab kev sib tshuam ntawm cov dej (tidal chav) sab hauv thiab sab nraum lub pob zeb loj yuav tsum to taub kom tsis txhob muaj lub voj voog qhuav thiab ntub nws tus kheej thiab ua rau muaj kev ntxhov siab; Nws yog ib qho tsim nyog yuav tsum nkag siab txog kev tsiv teb tsaws ntawm cov ntsev soluble hauv pob zeb thiab ua tib zoo saib xyuas qhov chaw ntawm cov ntsev tshem tawm thiab kev cais tawm hauv pob zeb loj. Zam kom tsis txhob muaj qhov hloov pauv hauv qhov kub thiab txias kom qeeb tus nqi ntawm kev puas tsuaj; Cov tshuaj tiv thaiv tus neeg sawv cev tuaj yeem nkag mus rau hauv pob zeb loj mus rau qhov tob tob los tiv thaiv kev ntxhov siab ntawm lub ntsej muag, los yog tsim kom muaj kev cuam tshuam ntawm hydrophobic gradient kom cuam tshuam qhov kev ntxhov siab ntawm lub ntsej muag. Cov saum toj no yog daim ntawv thov ntawm silicone nyob rau hauv kev tiv thaiv ntawm pob zeb kab lis kev cai relics. Koj puas to taub tag nrho lawv?
