Nekuvandudzwa kwehunyanzvi, jecha regirazi rinoshandiswa zvakanyanya; semuenzaniso, muindasitiri yemakemikari, jecha regirazi rinowanzoshandiswa mukushongedza kwezvigadzirwa zvegirazi. Mumakore achangopfuura, nekuvandudzwa kwehupenyu hwevanhu, vanhu vazhinji vanobhadhara zvakanyanya kune zvinodiwa zvekushongedza; pasi pemaitiro aya, kushandiswa kwezvinhu zvakadaro kwave kuchivandudzwa.
Yedu Photoluminescent agate zvidhinha anoshandiswa zvakanyanya kune inlays pamativi ese emigwagwa munzvimbo dzinoyevedza, mapaki nenzvimbo dzekugara. Iwo akafanana neagati agate jade masikati, iyo inofadza ziso; usiku, vanopenya uye vakadhakwa munzvimbo yakanaka.
Rosin ine 80% yerosin anhydride uye rosin acid, inenge 5 kusvika 6% ye resin hydrocarbon, inenge 0.5% yemafuta anoputika uye kutsvaga zvinhu zvinovava.
Mutengo weRosin Ester uri kuramba uchikwira. Kana iwe uine kubvunza kutsva nguva pfupi yadarika, Pls inzwa wakasununguka kutibata nesu
Jecha reQuartz yakakosha maindasitiri mamineral raw material. Iyo isiri-kemikari ine ngozi yezvinhu uye ine huwandu hwakawanda hwekushandisa, senge: girazi, ceramics, refractory zvinhu, kutakura kwemvura, kutakura chitima, kuvaka, makemikari maindasitiri uye mamwe maindasitiri. Nokuti haina ngozi, hapana dambudziko kune chero nzira yekufambisa.
Iko kushandiswa kwejecha regirazi rakapamhama, uye zvakare inobatsira zvakanyanya mumichina yemidziyo uye kuchenesa simbi. Haikwanise kubvisa chete marudzi ese emakina ezvikamu uye kuwedzera hupenyu hwesevhisi yemuchina, asi zvakare inovandudza kusakara kwavo kwekuora.
