Varnish Alcohol ay qoryihii

Baaxadda varnishes diyaariyey ku salaysan ee khamriga, quruxsan ballaadhan. Gaar ahaan, warshadaha ayaa isaga addoonsada soo saarka ee wax dahaadhka ranjiga ee alaabooyin kala duwan:

• gudaha iyo guriyo dhismayaasha;
• alaabta guriga,
• meelaha galaas;
• waxyaabaha meged dabiiciga ah;
• meelaha kale.

Sababo la xaqiiqada ah in varnish waa cusbi a kala diri ee khamriga, waqti qalajiyo buuxda ma aha ka badan kala bar ah ka badan hal saac. Sidaa awgeed, khamriga yeedhay varnishes, laga heli by Gaaxnuug dabiiciga ah Beeyada ee khamriga. Khubarada tilmaamay in ay heli blaastiigga yihiin waxqabadka sare iyo guryaha farshaxanka:

• nolosha batari dheer;
• xoog farsamoyaqaanka,
• aadka u adkaysi u iftiinka qoraxda;
• iftiin fiican.

On ku salaysan ee khamriga waa: shellac, rosin iyo carbinol varnishes.

varnish Shellac on salka khamriga

Sababo la xiriira hantida gaarka ah si fiican oo awood u shellac kala diri ee khamriga. The cusbi sida ugu dhakhsaha badan ee suurtogalka ah iyo in ka badan milma, waxa weeye si fiican dhulka Si aad u hesho a ganaax ah budada mass. Next, budo ka helay waa isku qasan oo leh ethanol boqolkiiba 92-95 boqolkiiba. Si aad si buuxda u milmaan dar cusbi waa ku filan kor u diiriyo 20 digrii, xilliyo aad salaantid ey isku keentay. The khamri sidaas heli la varnish cusbi in ay noqon filter wanaagsan in la baabi'iyo inclusions beelaya iyo nijaasta ahaa. Sida filtarrada loo isticmaalo in masaf galaas kiiska strainer this qalabaysan maro caadiga ah. content The boqolkiiba shellac ee xal sida u dhaxeysa 30 ilaa 45 boqolkiiba.

varnish shellac Qamriga siiyaa daahan filan adag, adkaysi u iftiin, laakiin ma adkeysan karaan isbedel heerkulka iyo gaadhista biyaha.

rosin varnish

The salaysan varnishes kuwanu waa Beeyada carbinol helay polymerization ee wax isku dardaro - dimetilviniletinilkarbinola. Of Beeyada waa kuwan ma aha oo kaliya rinji, laakiin xabagta loo adeegsado dhismaha iyo warshadaha. At heerkul ah 20 digrii iyaduu varnish this on dusha sare ee workpieces saacad badhkeed. Iyada oo ku xidhan kooban, varnish khamriga carbinol waa midab ama midab.

Varnishes isticmaalo in lagu daaweeyo meelaha qori

blaastiigga Kuwaasi waa hufan oo awood u howl gabka gloss dusha iyo xoojiso texture ku qori dabiiciga ah. varnishes Ruuxa qoryo hubkaas ayaa loo isticmaalaa in industry alaabta. Tan iyo markii ay aasaaska waa khamriga ethyl, waxay si dhakhso ah u qalalaan soo baxay, ka dibna u adeega sida ilaalinta lagu kalsoonaan karo oo ka mid ah meelaha lagu daaweeyaa ka qoraxda iyo arrimaha cimilada loo kasin.

alaabta ceeriin soo saarka ee varnishes ruux (sandarak, shellac, oo sidaas P. Acaroidea.) Ma aha oo kaliya in Russia, laakiin sidoo kale laga keeno dibadda. Miyaanay blaastiigga tayada ugu fiican ee ka soo jeeda shellac iyo shellac, kuwaas oo si ballaaran loo isticmaalo daahan qoryo iyo dhalooyinka meelaha. Currently technology bartay idiolom bedelo kuwaas Beeyada, cusbi phenolic dardaro. Si kastaba ha ahaatee, cusbi noocan oo kale ah waa ineysan ku varnish shellac khamri tayo leh, mana aha sidii raagaya iyo adkaysi meersan dibadda. Waxaa intaa dheer, Beeyada phenolic gudcur iftiinka.

varnish Alcohol-ku-saleysan qoryo been daaha khafiif iyo abuuraa filim hufan. Si uu hoosta ka xariiqo qaab dhismeedka on alwaax iftiinka waa in la isticmaalaa oo kaliya rinjiga dhalaalaya.
