Mhando dze pendhi

Kune marudzi akasiyana-siyana ependhi zvichienderana nekushandiswa. Semuyenzaniso, sezvinofananidzirwa nependhi uye vhanishi (varnish), kazhinji imvura uye inoomesa uye inonamatira nekuputika uye kuomeswa kweanonyungudutsa kugadzira firimu rekuputira pamusoro kuti rigadzirise uye kudzivirira kutaridzika kwechinhu. Neimwe nzira, ine yakaderera vhiskoti (viscosity), yakadai se steini yemafuta, inopinda mukati mezvinyorwa (munyaya iyi, rukuni), inodzivirira kuparara kwezvinhu pachayo, uye ine ruvara. Kune zvigadzirwa zvehunyanzvi zvezvinangwa zvakasiyana sezvivakwa, mastirakcha (structures), hambautare, mota dzakaita senjanji, ngarava, muchina wemagetsi, mapurodhakti esimbi, zvirimiso zvekurima nazvo, fenicha, matehwe, uye modhi.

KuJapani, mitemo yavo yakasiyana-siyana yezvigadzirwa zvezvigadzirwa zvezvigadzirwa zvemhando yemhando yemhando yemhando inotara kuti kunyora kunoitwa zvinoenderana nerudzi rwechikamu chikuru chekugadzira firimu rekukochekera, uye kunyanya, izvo zvine mafuta ekuomesa sechikamu chikuru anonyanya kupendhi ane mafuta uye nitrocellulose. Izvo zvinoshandiswa zvinofanira kunyorwa se lakieri (lacquer), avo vane rhezini (resin) yekugadzira sechinhu chikuru zvakanyorwa sependhi yakagadzirwa nependhi, uye avo vane shelaki (shellac) sechikamu chikuru zvakanyorwa sependhi inodhaka.

Munguva yakapfuura, yakawanda yepende yakasvibiswa ne masoruvhandi ari oganiki (organic solvents), asi munguva pfupi yapfuura, chikamu chependhi chinogona kuderedzwa nemvura mvura-based paints iri kuwedzera mukufungisisa kwezvakatipoteredza, hutano, nyore, nezvimwewo .. In kuwedzera, mapepa ehupfu , ayo ari mavara akaumbwa nechikamu chekugadzira ruvara uye chikamu chekugadzira firimu pasina kushandisa soruvhandi, akaonekwawo.
