Mavara emavara esimbi coils akapfuma uye ane mavara. Nzira yekusarudza sei ruvara runokodzera iwe pachako pakati pemavara akawanda esimbi coils? Kuti tidzivise kusiyana kukuru kwemavara, ngatitarisei pamwe chete.
Kusarudzwa kwemuvara wemuvara simbi yeplate coating: Kunyanya kutarisisa kwemavara kusarudzwa ndeyekufananidza nharaunda yakapoteredza uye zvido zvemuridzi. Nekudaro, kubva pakuona kwehunyanzvi, kune huwandu hwakawanda hwesarudzo dzepigment muchiedza chemavara machira. Inorganic pigments ine kusimba kwepamusoro (senge titanium dioxide) inogona kusarudzwa, uye iyo yekupisa inoratidzira kugona kwekupfeka kwakasimba (iyo yekuratidzira coefficient inopetwa kaviri iyo yakasviba ruvara runyoro). Muzhizha, kutonhora kwejira pachayo kunenge kwakaderera, izvo zvinobatsira pakuwedzera hupenyu hwekuputira.
Mukuwedzera, mupepeti anoyeuchidza kuti kunyange kana chifukidzo chichichinja ruvara kana upfu, mutsauko pakati pechifukidzo chemavara akajeka uye ruvara rwepakutanga idiki, uye kukanganisa pakuonekwa hakuna kukosha. Mavara erima (kunyanya mavara akajeka) anowanzo organic muruvara, uye anowanzo kupera kana akafumurwa nemwaranzi yeultraviolet, achichinja ruvara mumwedzi mitatu chete. Kune mavara akaputirwa simbi mahwendefa, iwo anopisa ekuwedzera mazinga ejasi uye ndiro yesimbi inowanzosiyana, kunyanya mutsara wekuwedzera coefficients wesimbi substrate uye organic coating zvakasiyana zvakanyanya. Kana iyo ambient tembiricha yachinja, iyo interface pakati pe substrate uye coating inosangana nekuwedzera kana contraction kushushikana. Kana isina kuburitswa zvakanaka, kuputika kwekuvhara kuchaitika.
Uyezve, zvinofanirwa kucherechedzwa kuti kune maviri asina kunaka pamusika wezvino: imwe ndeye kuvapo kwehuwandu hwemachena primer. Chinangwa chekushandisa chena primer kudzikisa ukobvu hwetopcoat, seyakajairwa corrosion-resistant primer yekuvaka yero yegirini (saka strontium chromate pigment) uye inofanirwa kuve neyakakwana topcoat ukobvu. Chechipiri ndiko kushandiswa kwemavara akavharwa ndiro dzesimbi muzvirongwa zvekuvaka. Iro purojekiti imwe chete inoshandisa vagadziri vakasiyana uye mabheti emavara akavharwa simbi mahwendefa, ayo anogona kuita seane ruvara rwakafanana panguva yekuvaka. Nekudaro, mushure memakore akati wandei ekuvhenekerwa kwezuva, maitiro ekuchinja kwemavara emajasi akasiyana kubva kune vakasiyana vanogadzira akasiyana, izvo zvinotungamira kune yakakomba misiyano yemavara. Kune mienzaniso yakawandisa yeizvi. Kunyangwe kune zvigadzirwa kubva kumutengesi mumwechete, zvinokurudzirwa zvakanyanya kuisa odha yepurojekiti imwechete kamwechete, sezvo nhamba dzakasiyana dzebatch dzinogona kushandisa zvigadzirwa kubva kune vakasiyana vatengesi vependi, zvichiwedzera mukana wekusiyana kwemavara.
