Dombo rekushandisa rinowanzoshandiswa mukugadzirwa kwemazuva ano. Vanoshongedza zvose masvingo ekunze edzimba , uye kubwinya kwemukati kwemakamuri. Dombo rekunyengedza nderomutambo wakaisvonaka uye rinoshandiswa mumhando dzakasiyana-siyana painoshongedza mukati nekunze. Uye iwe wakaziva here kuti ibwe rakadaro rinogona kuitwa pariri kushandisa maitiro akasiyana? Iyo ipurasitiki, yakaumbwa, polyurethane uye silicone. Chimwe nechimwe chezvinhu izvi zvine zvinhu zvaunoda kufunga paunenge uchitenga. Saka, ngatitsvakei kuti silicone molds ndeyeiyo mabwe anoitwa.
Kubatsira uye kusagadzikana kwe-silicone molds yebwe rekushongedza
Sezvazvinozivikanwa, mukugadzirwa kwebwe rekugadzira kazhinji rinoshandisa kora yakagadzirwa. Kusiyana ne polyurethane, silicone molds haisi iyo yakakonzerwa nechisimba chema alkaline yekrete sarudzo, uye ichi ndicho chisingaiti chikuru. Maitiro akadaro anokurumidzirwa kuparadzwa nekushandiswa kwakasimba. Gypsum haisi sechisimba sekrete, asi apo inosangana neSilicone, inopa kuipa kusingagumi kwemabvu anowanikwa nechemberi kwechigadzirwa. Uye chikamu chechitatu chekakisi ye-composic silicone haisi mari yakaderera: silicone molds pakugadzira mabwe anokosha zvinodhura kupfuura mapurasitiki.
Nezvakanakira, iyo silicone ichiri yakasimba kudarika plastiki kana plastiki. Mukuwedzera, iyo inoendesa kununurwa zvakanyatsonyatsojeka, iyo inokosha apo ichiedza kuita pasi pasi pebwe nemubatsiro weSilicone molds. Kwavari, shrinkage deformations haisiwo yakasiyana, sezvo silicone zvinhu zvakanyanyisa uye zvisingatauriki. Zviri nyore kuti reusable silicone molds pamatombo ematombo anobvumira nyore kubviswa kwechigadzirwa chakapedzwa.
Nzira yekuita sei silicone molds yebwe?
Maitiro akadaro anogona kuitwa nemaoko avo. Saka, teknolojia yekugadzirwa kwavo ndeiyi:
- Sarudza bhokisi rakagadzirirwa rakagadzirirwa kugadzira mafuta (matrix) kana kuzviita iwe pachako. Inofanira kuitwa nemashoko akaoma, akadai se chipboard, fiberglass, mapuranga emapuranga, nezvimwewo. Ndapota cherechedza kuti hapanofanira kuva nemapapakati pakati pemakona ebhokisi rakadaro, iyo inoshandiswa kuvuza kwesilicone.
- Pasi pematrix tinoisa zvigadzirwa zvepurasitiki (kwete kuzvitambudza, asi kazhinji). Rongedza kuvhara kwayo kusvika nehafu yebhokisi. Plasticine inofanira kunge yakanyatsokonzerwa, kuitira kuti igare yakadzika uye kunyange.
- Kubva kumusoro paPlastikiine tinoisa mufananidzo wekuti fomu yacho inogadzirwa. Inogona kuva dombo rehupi chero ipi zvayo kana tile yakagadzirira pasi pebwe.
- Kuti udzivise kuchinja kwechimiro, zvinodiwa kuti uite mabheti mazhinji muvhu mune ramangwana - kuvhara.
- Iye zvino tinoverenga kuti zvinhu zvakakura zvakadini zvekuvaka fomu zvinodiwa. Kuti uite izvi, tora chero zvigadzirwa zvakawanda, uidururire muchiganda, wozoidururira zvakare mumukombe wokuyeresa uye uenzanise ivhu.
- Ipapo matrix inofanira kurapwa neparadziri. Inogona kuva soapy
mhinduro, mafuta, wax kana kuparadzaniswa kwakasiyana-siyana. Usashandise chero mabheti anoenderana ne-silicone. - Sakanidza zvishandiso zvekuumbisa sezvakaratidzwa mumirayiridzo, uye udira yesilicone mukati mematrikisi. Izvi zvinofanira kuitika zvakanaka, muchitsipa chakaonda, kutanga nehutambo hwekugadzirisa kuchengetedza kuumbwa kwemabvu.
- Apo chikamu chepamusoro chinova chakasimba, plastiki inofanira kunyatsocheneswa, pamusoro uye mufananidzo inofanira kuiswa neparadziri uye yobva yadururirwa ne-maviri-chikamu mold silicone.
- Rimwe zuva gare gare chimiro chakaparadzaniswa, uye mufananidzo wacho unotorwa kubva mumatrice. Yakagadzirira kushandisa!
