Macellulose ethers akachengeteka here kuchengetedza mifananidzo?

Cellulose ethersanowanzoonekwa seakachengeteka pakuchengetedza mifananidzo kana akashandiswa zvakakodzera uye maererano nemaitiro ekuchengetedza akasimbiswa.Aya mapolymers anotorwa kubva ku cellulose, senge hydroxyethyl cellulose (HEC), hydroxypropyl methylcellulose (HPMC), carboxymethylcellulose (CMC), uye mamwe, anopa akati wandei anobatsira ekuchengetedza zvinangwa.Nekudaro, zvakakosha kuti utarise zvinhu zvakananga kuti uve nechokwadi chekushandisa kwavo kwakachengeteka uye kunoshanda:

Zvekuchengetedza:

1. Kuenderana kwezvinhu:
   • Ongorora kuenderana kwe cellulose ethers nezvinhu zviripo mumifananidzo, zvinosanganisira substrates, pigment, dhayi, uye zvimwe zvikamu.Kuyedzwa kwekuenderana pane diki, nzvimbo isingaonekwe inokurudzirwa.
2. Conservation Ethics:
   • Teerera kutsika dzekuchengetedza dzakasimbiswa, dzinoisa pamberi pekurapa kudzoreredzwa uye kushoma kurapa.Ita shuwa kuti kushandiswa kwe cellulose ethers kunoenderana nemisimboti yekuchengetedza nhaka yetsika.
3. Kuedza uye Miedzo:
   • Ita bvunzo dzekutanga uye zviedzo kuti uone iko kwakaringana, nzira yekushandisa, uye inogona kukanganisa cellulose ethers pane chaiyo artwork.Izvi zvinobatsira pakuziva nzira yakakodzera yekurapa.
4. Reversibility:
   • Sarudza cellulose ethers inopa dhigirii reversibility.Reversibility musimboti wakakosha mukuchengetedza, uchibvumira kurapwa kana kugadzirisa kweramangwana pasina kukuvadza kune yekutanga zvinhu.
5. Zvinyorwa:
   • Nyora marapiro ekuchengetedza zvakakwana, kusanganisira ruzivo rwema cellulose ethers anoshandiswa, kutarisisa, uye nzira dzekushandisa.Zvinyorwa zvakakodzera zvinobatsira mukujeka uye kunzwisisa nhoroondo yekuchengetedza yemifananidzo.
6. Kudyidzana neConservators:
   • Bata pamwe nenyanzvi dzekuchengetedza vane hunyanzvi mune zvakanangana kuchengetedza zvinodiwa zvehunyanzvi.Conservators vanogona kupa ruzivo rwakakosha uye gwara mukushandiswa kwakachengeteka uye kunoshanda kwe cellulose ethers.

Zvakanakira Kuchengetedza:

1. Kubatanidza uye Kusimbisa:
   • Cellulose ethers, senge hydroxyethyl cellulose, inogona kushanda mukubatanidza nekusimbisa zvinhu zvisina kusimba kana kuparara mumabasa emifananidzo.Vanobatsira kusunga zvimedu zvakasununguka uye kudzikamisa chimiro.
2. Adhesive Properties:
   • Mamwe cellulose ethers anoshandiswa seanonamira pakugadzirisa mabasa emifananidzo.Vanopa zvisungo zvakasimba uye zvinogara kwenguva refu pasina kukonzera ruvara kana kukuvadza kana zvichishandiswa zvakakodzera.
3. Kunzwa Kwemvura uye Kuramba:
   • Cellulose ethers inogona kusarudzwa nekuda kwekusagadzikana kwemvura, kudzivirira kuparara kana kukuvadzwa pakubata nehunyoro.Ichi chivakwa chakakosha kune mabasa emifananidzo anogona kuoneswa nemamiriro ekunze kana kuita kuchenesa maitiro.
4. Kugadzira Mafirimu:
   • Mamwe ma cellulose ethers anobatsira pakuumbwa kwemafirimu ekudzivirira, kuwedzera kugadzikana uye kusimba kwenzvimbo dzakarapwa.

Indasitiri Standards uye Mazano:

1. ICOM Code of Ethics:
   • Tevedzera iyo International Council of Museums (ICOM) Code of Ethics for Museums, iyo inosimbisa basa rekuchengetedza nekuchengetedza nhaka yetsika uchiremekedza huchokwadi uye kuvimbika kwemabasa emifananidzo.
2. AIC Code of Ethics:
   • Teerera kuAmerican Institute for Conservation (AIC) Code of Ethics uye Mirayiridzo Yekuita, iyo inopa maitiro ehunhu nemisimboti kune nyanzvi dzekuchengetedza.
3. ISO Standards:
   • Funga zvinoenderana nemitemo yeISO yekuchengetedza, senge ISO 22716 yezvizoro uye ISO 19889 yekuchengetedza nhaka yetsika.

Nekunyatsotarisisa zvinhu izvi uye nekutevera nhungamiro dzakatarwa uye zviyero, vanochengetedza vanogona kushandisa cellulose ether zvakachengeteka uye zvinobudirira mukuchengetedza mabasa emifananidzo.Kudzidziswa kwakakodzera, zvinyorwa, uye kubatana nenyanzvi dzekuchengetedza zvinhu zvakakosha zvekuona mhedzisiro yakanakisa yekuchengetedzwa kwenhaka yetsika.
