Mowa varnish nkhuni

Mbali vanishi anakonza pa maziko a mowa, wokongola waukulu. Makamaka, makampani wakhala katswiri kupanga utoto ❖ kuyanika nkhani ya mankhwala osiyanasiyana:

• Interiors ndi pamakoma a nyumba;
• mipando;
• galasi pamalo;
• mankhwala chikopa achilengedwe
• pamalo ena.

Chifukwa chakuti mu varnish ndi utomoni kusungunuka mowa, zonse kuyanika nthawi osapitirira theka la ola. Choncho, mowa otchedwa vanishi, akamagwira Kutha resins zachilengedwe mowa. Akatswiri amanena kuti iwo apeza zokutira ndi ntchito yapamwamba ndi katundu zokongoletsa:

• yaitali moyo batire;
• mphamvu mawotchi;
• kugonjetsedwa kwambiri kwa dzuwa;
• zabwino kuwala.

Pamaziko a mowa: shellac wopambana, ayendetse ndi carbinol vanishi.

Shellac varnish pa m'munsi mowa

Shellac - mtundu wa zinthu utomoni wonunkhira zomera ndi kugonjetsa m'madera otentha. Pakali pano, dzinali lakhala likugwiritsidwa ntchito kwambiri kupanga vanishi ndi mapulasitiki. Chifukwa katundu wake wapadera bwino angathe shellac kusungunuka mowa. The utomoni mwamsanga ndi zambiri sungunuka, izo bwinobwino kuuluka kupeza ufa misa chabwino. Kenako, ufa analandira ndi wothira 92-95 peresenti Mowa. Kupasuka kwathunthu osakaniza utomoni ndi mokwanira kutenthetsa digiri 20, nthawi kugwedeza osakaniza chifukwa. The mowa Choncho analandira ndi utomoni varnish kukhala fyuluta bwino kuthetsa inclusions insoluble ndi zosafunika. Monga Zosefera ntchito mu nkhani galasi nyuzi okonzeka strainer ichi cha nsalu ochiritsira. Chiwerengero zili shellac mu njira ngati ranges ku 30 peresenti 45.

Mowa shellac varnish amapereka mokwanira amphamvu ❖ kuyanika, kugonjetsedwa ndi kuwala, koma sangaime kusintha kutentha komanso kukhudzana ndi madzi.

rosin varnish

• 20 ga turpentine;
• 80 ga 95% mowa.

N'zochititsa chidwi kuti rosin si maziko a varnish. Iwo bwino ntchito monga chuma m'munsi mwa kupanga mastics.

Rosin mowa varnish ali ndi mtengo wotsika, koma ndi osiyana ❖ kuyanika mphamvu.

carbinol varnish

Maziko a vanishi awa carbinol resins akamagwira polymerization zakuthupi kupanga - dimetilviniletinilkarbinola. Wa resins izi osati kujambula, koma zomatira ntchito pomanga ndi mafakitale. Pa kutentha madigiri 20 uphwetsa varnish ichi padziko workpieces kwa theka la ora. Malinga zikuchokera, carbinol mowa varnish ndi achikuda kapena colorless.

Vanishi ntchito pochiza nkhuni pamalo

zokutira oterowo ndi chimaonekera ndipo amatha yopatsa pamwamba gloss ndi kulankhula zachilengedwe nkhuni kapangidwe. vanishi Mzimu nkhuni ankagwiritsa ntchito makampani mipando. Popeza maziko awo ndi mowa ethyl, iwo mwamsanga youma ndi kutumikira monga chitetezo chodalirika wa pamalo azisonyeza dzuwa ndi chokhwima zinthu nyengo.

zipangizo za ulimi wa vanishi mzimu (sandarak, shellac, ndi zina Acaroidea. P.) Kodi osati Russia, komanso kunja kwa kunja. Zabwino zokutira khalidwe anachokera ku shellac ndi shellac, zomwe ankagwiritsa ntchito wokutira nkhuni ndi galasi pamalo. Panopa luso anaphunzira idiolom m'malo resins awa, kupanga phenolic utomoni. Komabe, ngati utomoni ndi otsika quality mowa shellac varnish, si monga cholimba ndi kugonjetsedwa zikuchitika kunja. Komanso, phenolic resins mdima kuunika.

Mowa ofotokoza varnish nkhuni pagona wosanjikiza woonda ndi kutitengera mandala filimu. Kuti bwino dongosolo pa mtengo kuwala ayenera kugwiritsidwa ntchito utoto wowala.

Kugwirizana mzimu vanishi

Malinga ndi kuchuluka kwa utomoni m'gulu zikuchokera, mzimu vanishi anawagawira m'magulu awa:

1. Kwenikweni vanishi (30% utomoni).
2. Polishes (zosakwana 30% a utomoni wa).

Zochizira pamalo matabwa ntchito advantageously turbid mowa shellac varnish, amene sanadziyeretse lochokera ku sera. Ndi ngakhale phindu chifukwa sera amatha kuononga mabowo zabwino kapangidwe ka pamalo nkhuni.

Khalidwe lacquer zinali opanda cholakwa, pamene oyambitsa kugwirizana mowa ndi zosavomerezeka kugwiritsa ntchito zigawo zikuluzikulu mu zikuchokera amene ali chitsulo. Mu ntchito mogwirizana ndi kuti njira mchitidwe shellac amakhala akuda. Komanso, zinabala madipoziti osafunika si ataphimbidwa ndi luso lacquer kupanga.

nthawi chofunika kupanga polishes, kwa maola 3 mpaka 5. Mu kupanga lacquer zimatenga nthawi zambiri maola 7 mpaka 9. masiku More (maola 24 kuti 40) wofunikila kupanga vanishi wandiweyani copal. Kuti kusinja zimachitika mofulumira, ndi osakaniza ndi mkangano, pamene kuonetsetsa yogwira zonse njira.

Anapangira njira zoyambirira za resins

1. Mowa sungunuka kukumba (yokumba ndi makilogalamu 60 75-90 makilogalamu mowa).
2. Shellac (40 ndi 65 makilogalamu, motero).
3. Rosin (makilogalamu 60 60 kg).
4. Berestovaya utomoni (35-40 makilogalamu 60-65 makilogalamu, motero).
5. Sandarac (makilogalamu 60 pa 100 kg).
6. Shellac (45 makilogalamu 90 kg).
7. Iditol (30-40 kg 60-65 makilogalamu, motero).

Kuti kufunika kugwirizana kutchulidwa njira bwinobwino wosakaniza ndi pang'ono mkangano. njira sandarac ndi copal ntchito mu vanishi lithographic mankhwala pamalo zoimbira. vanishi Lithographic ayenera kupereka gloss zipangizo kukonzedwa ndi zilibe zilowerere mu pepala. Shellac varnish, anafuna kuti mankhwala a matabwa, sali pansi zosefera. Iwo anadutsa mauna za mkuwa. Chifukwa cha zimenezi amaperekedwa ndi makina kuchotsa zosafunika lapansi.
