Chifukwa nthawi kukhazikitsa ndi kukonzanso mfundo golide ndi siliva ndalama, ndi kupatuka osiyanasiyana ndi chiwerengero cha mano ulusi otchulidwa mu mfundo si ntchito ndalama zonse zamtengo wapatali chikumbutso zitsulo, makamaka oyambirira anapereka ndalama chikumbutso.
Kuzindikiritsa ndondomeko ya ndalama zachitsulo zachikumbutso
Njira yopangira ndalama zachitsulo zamtengo wapatali zachikumbutso makamaka imaphatikizapo kupopera mchenga / kupopera mikanda, galasi pamwamba, zithunzi zosaoneka ndi zolemba, zojambula zazing'ono ndi zolemba, kusindikiza mitundu yosindikizira / kujambula utoto, ndi zina zotero. Mirror kumaliza ndondomeko. Kupopera kwa mchenga / mkanda ndiko kugwiritsa ntchito mitundu yosiyanasiyana ya mchenga (kapena mikanda, komanso kugwiritsa ntchito lasers) kupopera zithunzi zosankhidwa kapena malo a nkhungu pamtunda wachisanu, kupanga mchenga ndi matte pamwamba pa chikumbutso chojambulidwa. ndalama. Njira yagalasi imatheka ndi kupukuta pamwamba pa chithunzi cha nkhungu ndi keke kuti apange chithunzithunzi chonyezimira pamwamba pa ndalama zachikumbutso zosindikizidwa.

Ndi bwino kufananiza ndalama zenizeni ndi mankhwala omwe amayenera kudziwika, ndikupanga kufananitsa mwatsatanetsatane kuchokera kuzinthu zosiyanasiyana. Njira zothandizira kumbuyo kwa ndalama zachikumbutso zachitsulo zamtengo wapatali zimasiyana malinga ndi mutu wa polojekitiyo, zomwe zimapangitsa kuti zikhale zovuta kusiyanitsa zowona kupyolera mu mpumulo kumbuyo popanda kufanana ndi ndalama zenizeni kapena zithunzi zodziwika bwino. Pamene mikhalidwe yofananitsayo sinakwaniritsidwe, chidwi chapadera chiyenera kuperekedwa ku chithandizo, sandblasting, ndi galasi processing zotsatira za mankhwala kuti adziwike. M'zaka zaposachedwapa, ndalama zambiri za golidi ndi siliva zomwe zatulutsidwa zakhala ndi njira zothandizira pa kachisi wa Kumwamba kapena chizindikiro cha dziko. Osonkhanitsa amatha kupewa ngozi yogula ndalama zachinyengo pofufuza ndi kuloweza pamtima mawonekedwe amtunduwu wamba.

M'zaka zaposachedwapa, ndalama zina zachinyengo zapezeka kuti zili ndi njira zothandizira kutsogolo zomwe zili pafupi ndi ndalama zenizeni, koma ngati zizindikiridwa bwino, luso lawo limakhala losiyana kwambiri ndi ndalama zenizeni. Kuphulika kwa mchenga pamtunda weniweniwo kumapereka mawonekedwe ofanana, osakhwima, komanso osanjikiza. Kuphulika kwina kwa laser sandblasting kumatha kuwonedwa mu gridi mawonekedwe pambuyo pakukulitsidwa, pomwe kuphulika kwa mchenga pa ndalama zachinyengo kumakhala koyipa. Kuphatikiza apo, galasi pamwamba pa ndalama zenizeni ndi lathyathyathya komanso lonyezimira ngati galasi, pomwe galasi pamwamba pa ndalama zachinyengo nthawi zambiri imakhala ndi maenje ndi tokhala.
