Kuchengetedzwa kweArtwork inzira yakatetepa uye yakaoma kunzwisisa inoda kunyatsosarudzwa kwezvinhu kuti ive nechokwadi chekuchengetedza uye kutendeseka kwezvimedu zveunyanzvi.Cellulose ethers, boka remakomboni akatorwa kubva ku cellulose, vakawana maapplication mumaindasitiri akasiyana ezvimiro zvavo zvakasiyana, kusanganisira kukora, kudzikamisa, uye kuchengetedza mvura.Munzvimbo yekuchengetedzwa kwemifananidzo, kuchengetedzwa kwecellulose ethersipfungwa yakakosha.Iyi ongororo yakazara inoongorora kuchengetedzwa kweselulosi ethers, ichitarisa kumhando dzakajairwa dzakadai seHydroxypropyl Methylcellulose (HPMC), Ethyl Hydroxyethyl Cellulose (EHEC), uye Carboxymethyl Cellulose (CMC).
1. Hydroxypropyl Methylcellulose (HPMC)
a.Common Use
HPMC inowanzo shandiswa mukuchengetedza zvivakwa zvayo zvekuchengeta mvura.Hunhu hwayo hwakasiyana-siyana hunoita kuti ive yakakodzera kugadzira zvinonamira uye zvinobatanidza mukudzoreredza kwezvigadzirwa zvemapepa.
b.Mifungo Yekuchengetedza
HPMC inowanzoonekwa seyakachengeteka kuchengetedza mifananidzo kana yakashandiswa zvine hungwaru.Kuenderana kwayo neakasiyana-siyana ma substrates uye kushanda kwayo mukuchengetedza kurongeka kwemaitiro emapepa emifananidzo kunobatsira pakugamuchirwa kwayo mumunda wekuchengetedza.
2. Ethyl Hydroxyethyl Cellulose (EHEC)
a.Common Use
EHEC imwe cellulose ether inoshandiswa mukuchengetedza kukora uye kudzikamisa zvinhu.Inogona kushandiswa mumhando dzakasiyana-siyana kuti uwane maitiro aunoda.
b.Mifungo Yekuchengetedza
Zvakafanana neHPMC, EHEC inoonekwa seyakachengeteka kune mamwe maapplication ekuchengetedza.Kushandiswa kwayo kunofanirwa kuenderana nezvinodiwa zveiyo artwork uye kuve pasi pekuyedzwa kwakakwana kuti ive nechokwadi chekuenderana.
3. Carboxymethyl Cellulose (CMC)
a.Common Use
CMC, nekukora uye kudzikamisa zvivakwa, inowana kushandiswa mumaindasitiri akasiyana, kusanganisira kuchengetedza.Inosarudzwa zvichienderana nekukwanisa kwayo kugadzirisa viscosity yemhinduro.
b.Mifungo Yekuchengetedza
CMC inowanzoonekwa seyakachengetedzeka kune chaiyo kuchengetedza zvinangwa.Yayo kuchengetedza chimiro inoita kuti ive yakakodzera kushandiswa mumagadzirirwo anoitirwa kudzikamisa nekudzivirira mabasa emifananidzo, kunyanya munzvimbo dzakadzorwa.
4. Kuchengetedza Maitiro Akanakisisa
a.Testing
Vasati vashandisa chero cellulose ether kumifananidzo, vanochengetedza vanosimbisa kukosha kwekunyatsoongorora panzvimbo diki, isingatarisike.Iyi nhanho inovimbisa kuti zvinyorwa zvinopindirana nemifananidzo uye haina mhedzisiro yakaipa.
b.Consultation
Art Conservators uye nyanzvi dzinoita basa rakakosha mukuona zvakanyanyokodzera zvinhu uye nzira dzekuchengetedza.Unyanzvi hwavo hunotungamira kusarudzwa kwe cellulose ethers uye zvimwe zvinhu kuti uwane izvo zvinodiwa kuchengetedza mhedzisiro.
5. Regulatory Compliance
a.Kuomerera kuMitemo
Maitiro ekuchengetedza anopindirana nemwero chaiwo uye nhungamiro kuti ive nechokwadi chepamusoro chepamusoro chekutarisira mabasa emifananidzo.Kutevedza zviyero izvi kwakakosha pakuchengetedza kuchengetedzwa nekuvimbika kwemaitiro ekuchengetedza.
6. Mhedziso
cellulose ethers seHPMC, EHEC, uye CMC inogona kunzi yakachengeteka kuchengetedza mifananidzo kana ichishandiswa zvinoenderana neakanakisa maitiro.Kunyatsoedza, kubvunzana nenyanzvi dzekuchengetedza, uye kutevedzera zviyero zvakakosha pakuona kuchengetedzwa uye kushanda kwe cellulose ether mukuchengetedza mabasa emifananidzo.Sezvo basa rekuchengetedza richishanduka, tsvakiridzo inoenderera mberi nekushandira pamwe pakati penyanzvi zvinobatsira mukukwenenzverwa kwemaitiro, kupa maartist nevanochengetedza maturusi akavimbika ekuchengetedza nhaka yedu yetsika.
