Zviri nyore kwazvo kuti uzvivhiringidze mune zvakasiyana-siyana zvezvinhu pamusika pakupedzisa imba, vese vatengesi vanomiririra kuti iyo inzvimbo yavo inopisa ndiyo yakanakisisa. Asi zvino inosvika pakuti iyo haina kukwana zvachose nemararamiro akanyorwa, kupamba kubva mumvura kana kuva nekunhuhwa kusinganzwisisiki. Nokudaro, pano tinonyora zvakanyanya kushandiswa kwemhando yeii yekushongedza mukati, kuitira kuti mutengi haasi kurasikirwa muchitoro apo achitenga zvinhu zvakanaka pamusi wekuwanda kwekugadzirisa musha.
Nei pende yakakamurwa kuva marudzi akasiyana?
Apo patinoshandisa kuumbwa kwemavara kumusoro, tinowana finnin yefinnest ine zvikamu zvitatu. Iyo inonyanya kuchinja inonyanya kukoshesa maitiro emukati pepende. Chinhu chekutanga chinotakura chinotakura nguva pfupi mushure mekushandisa zvinyorwa kusvika padenga, fesheni kana masvingo. Chinhu chechipiri ndicho chinyorwa chinokonzera kupara. Chikamu chechitatu, icho chinogara chiripo pamapuranga, ndicho chibvumirano chinobvumira zvikamu zvakanakisa zveiyo pigment kuti zvibatanidze kumusoro. Muchidzidzo ichi, tichaparadzanisa pende muzvipenyu zvichienderana ne substrate.
Mhando dzepakati pepende:
- Mafuta pepende.
- Para-based based peji inobva paPVA.
- Acrylic water-based paints.
- Alkyd Enamel.
- Latex inoronga.
Zvigadzirwa zvakadai zvinokonzerwa pamusana pekuoma mafuta, kamwe chete pakange pasina makwikwi uye yakakurumbira zvikuru. Iyo pende yakaoma kwenguva yakareba, kupfeka "hakufemera" uye kwenguva yakareba inopa kunhuhwirira kwakashata. Mushonga wokutanga wakachena wepamusoro unotarisirwa, zvisinei, iyo firimu yakaisvonaka inowanikwa ichanyunguduka. Iko mari yekunyora kwemafuta inonakidza chaizvo. Mukuwedzera, iyo mikoko yakaoma yakave yakachengeteka yehutano, inoshandiswa zvakaderera, inopinda zvakanaka muhuni uye inonyatsopikisana nekemikari.
Nheyo yemiti yose inoparadzirwa nemvura inowanzova mvura, inoita kuti ive yakakosha yekupedzisa chivakwa chekugara. Polyvinyl acetate formulations ndiyo yakasiyana-siyana yakasiyana-siyana. Iko, zvose matte uye girazi mukati-kati peji-yakagadzirwa pepa. Shandisa izvi zvisingabatsiri uye zvakakosha zvakagadzirwa nemishonga yekurapa masvingo akagadzirwa nemapurasitiki nemapuranga, mapurasitiki, zvipfeko.
Hazvibvumirwi kupora zvinhu izvi nemishonga yematare uye mashizha akajeka. Nzira yechipiri yekudengenyeka kwepakati iyi yepende ndiyo kusagadzikana kwemvura, nekuda kweizvi zvinokurudzirwa kushandiswa mukurapa masvingo uye denga chete mumakamuri akaoma.
Mvura inowedzerawo, asi polyacrylates (mapuroymeri e methyl, ethyl uye asiyl acrylates) inoumba chinhu chinogadzirwa nefirimu. Zvitsva zvitsva zviri nyore kubvisa, asi mushure mokupwa, kupfekedzwa kwekunze hakutyi kunatswa kwemvura. Kunyange zvakadaro, tinocherechedza kuti kune dzimba uye mudziki zvakakodzera kutarisa mamwe mavara akatendeseka.
Mukugadzirwa kwemakemikisi akadaro, alkyd varnishes yemhando mbiri anoshandiswa: glyptal uye pentaphthalic, uyewo inogadzirisa zvinogadzirwa. Ichi chisanganiswa chinokubvumira kuti uwane mushure mokuveza muchero unogara kwenguva refu uye unofadza, unokurudzirwa kushanda, zvose zviri mukati memabasa uye mumugwagwa. Yakashama mukati mehuni mukati mepende haitambudziki mhepo, haifaniri kuvhara, ndeyezvakanaka
Zvakanakisisa zvemazuva ano kunyorwa kwemashoko zvakasiyana. Kune mvura-kuparadzaniswa latex paints uye acrylic-latex mvura-kupararira paints. Acrylate zvinhu zvinodhura zvakanyanya, asi zvinowedzera, iyo yepurasitiki yepende inenge yakakodzera yekicheni, yekugadzirisa masvingo uye chidimbu mumugodhi kana mudzimba dzokugeza.
