Resin muto wakakora kubva kune zvakasikwa. Miti yakasiyana-siyana inoda kuishandisa kurapa kukuvara kwepamusoro. Zvisinei, munhu akadzidzawo kugadzira resin dzakasiyana-siyana. Anorishandisa kugadzira pendi nezvinonamira. Mumwe anobva ataura nezve "artificial resin".
Resin inozivikanwawo seamber. Amber haisi chimwe chinhu kunze kweresin yakaomeswa kwemamiriyoni emakore. Dzimwe nguva mhuka diki inovharirwa mukati, kazhinji bete kana chimwe chipembenene.
Chii chaunoda kuziva nezve natural resin?
Natural resin inonyanya kuwanikwa mumaconifers. Muhupenyu hwezuva nezuva, mvura yose inonzi "resin". Ndizvo zvimwe chete muzvirevo izvi.
Muti unoda kushandisa resin kuvhara maronda mumakwati. Zvakafanana nezvatinoita kana tichikwesha ganda redu. Ropa rinobva ragwamba pamusoro uye roita mutsetse mutete, kureva chikwee. Kukuvadzwa kwemuti kunokonzerwa, semuenzaniso, nenzwara dzemapere kana nemhembwe, mhembwe dzvuku, uye dzimwe mhuka dzinobaya pamakwati. Muti uyu unoshandisawo resin kugadzirisa zvinenge zvakonzerwa nezvipembenene.
Vanhu vakacherechedza kare kuti huni hunopisa hunopisa zvakanyanya uye kwenguva yakareba. Mipine ndiyo yainyanya kufarirwa. Dzimwe nguva vanhu vaitosvuura makwati emuti kakawanda. Izvi hazvina kungounganidza resin yakawanda pamusoro pehuni asiwo mukati. Huni iyi yakachekwa ikatsemurwa kuita zvidimbu zvinyoro. Iyi ndiyo nzira yakagadzirwa Kienspan, iyo yakapisa kwenguva yakareba. Yakaiswa pamubati kuti ivheneke. Huni dzepaini shavings dzaigonawo kuwanikwa kubva pazvigutsa zvemuti.
Kusvikira anenge makore zana apfuura, kwakanga kune rimwe basa rinokosha, Harzer. Akacheka makwati emiti yomupaini zvokuti tuno twakabva twapinda mumugomo muduku waiva nechepasi. Akatanga ari pamusoro pemuti achibva adzika zvishoma nezvishoma. Iyi ndiyo nzira iyo caoutchouc ichiri kubudiswa nayo nhasi kugadzira rabha kubva mairi. Zvisinei, resin inogonawo kuwanikwa ne "kubika" zvidimbu zvehuni mumavheni anokosha.
Resin yakashandiswa nenzira dzakasiyana-siyana munguva yakapfuura. Kare seStone Age, vanhu vainamira matombo ematombo pamibato yematemo. Yakasanganiswa nemafuta emhuka, yakazoshandiswa kuzora maekisero engoro kuitira kuti mavhiri afambe nyore. Pitch yaigonawo kutorwa kubva muresin. Rombo rakaipa rinonamira zvakanyanya. Mhanza yakaipa yakapararira pamapazi, semuenzaniso. Shiri payaigara pairi, yakanamira uye yakazodyiwa nevanhu. Akabva angoti "unlucky".
Gare gare, resin yakashandiswawo mukurapa. Pakagadzirwa zvikepe, mikaha pakati pemapuranga yakavharwa neresin uye hemp. Vanyori vakashandisa resin, pakati pezvimwe zvinhu, kusunga hupfu hwepende.
Ko nyanzvi dzinofungei nezve resin?
Kune nyanzvi, zvisinei, chikamu chimwe chete chemuti resin ndiro resin chaiyo. Mumakemikari, resin kubva pamiti ine zvinhu zvakasiyana-siyana. Kana zvikamu zve resin zvakasanganiswa nemafuta, inonzi balm. Yakasanganiswa nemvura inonzi "gum resin" mushure mekuoma.
Kune akawanda akasiyana marudzi esynthetic resin. Izvo zvinogadzirwa mumafekitari emakemikari. Zvigadzirwa zveizvi zvinobva mupetroleum.
