Ivanishi Alcohol zokuba ziinkuni

Scope ivanishi ziqulunqwe ngokwendlela yecash utywala, pretty ebanzi. Ngokukodwa, ushishino Iyakwazi ukuveliswa kwezinto ipeyinti enamathela iimveliso ezahlukeneyo:

• ngaphakathi kunye olungaphambili lwezakhiwo;
• yasendlini;
• imiphezulu zeglasi;
• iimveliso ngesikhumba yendalo;
• nakwezinye izinto.

Ngenxa yokuba kule ivanishi kukho intlaka zichithakala nje ngotywala, ixesha yokomisa epheleleyo ayikho ngaphezu kwesiqingatha seyure. Ngoko ke, ebizwa ivanishi utywala, elifunyenwe ezinyibilikayo nentlaka endalo utywala. Iingcali zibonisa ukuba ufumene Ipeyinti kukho namaziko asebenza kwizinga eliphezulu kunye neepropati yobuhle:

• ubomi bebhetri elide;
• amandla mechanical;
• linamandla kakhulu ilanga;
• bukhanye nice.

Ngenxa yokuba utywala zezi: shellac, rosin kunye carbinol ivanishi.

Shellac ivanishi kwi kwisiseko utywala

Shellac - uhlobo kwezinto emnandi zezityalo, yaye ephumelela kwiindawo emvula sabutropikhi. Okwangoku, liye lasetyenziswa ngokubanzi ekwenziweni ivanishi kwakunye zeplastiki. Ngenxa yokuba iimpawu zayo ezizodwa kakuhle ziyakwazi shellac unyityilikiswa utywala. Le resin ngokukhawuleza kangangoko kunokwenzeka kwaye enyibilikayo ngakumbi, ukuba ngokupheleleyo walisila ifikelele kubunzima entle ngumgubo. Emva koko, lo umgubo endibufumeneyo axutywe cent 92-95 ngalinye ethanol. Ukunyibilika ngokupheleleyo umxube intlaka ngokwanele ukufudumala ukuya degrees 20, hlale ishukumisa umxube ngenxa. Le utywala ukuzithengela kunye ivanishi intlaka ukuba icebo lokucoca elungileyo ukuphelisa inclusions ezingenakunyibilika kunye ukungcola. Njengoko amacebo asetyenziswa kulo iglasi mzekelo ifanele kwesisefo exhotyiswe somchako oluqhelekileyo. Ipesenti Umxholo shellac kwi izisombululo ezinjalo isusela ukususela-30 ukuya kwezingama-45 ekhulwini.

Ezinxilisayo shellac ivanishi unika ukutyabeka ngokwaneleyo ezinzima, ukumelana ukukhanya, kodwa ayikwazi ukumelana utshintsho lobushushu nokuqhelana namanzi.

rosin ivanishi

Njengesiseko iipeyinti ezinjalo ezisetyenzisiweyo rosin. It - nentlaka yemifuno, livela unyango iinkuni pine. Ukuzinza rosin ivanishi lumi ngolu hlobo lulandelayo:

• 110 g rosin;
• 20 g turpentine;
• 20 g turpentine;
• 80 g 95% utywala.

Kuyaphawuleka ukuba rosin ayikho kuphela sisiseko ivanishi. Oku kusetyenziswa izinto isiseko ekwenziweni mastics ngempumelelo.

Rosin utywala ivanishi abe ngendleko ephantsi, kodwa yahlukile amandla ngeso lenyama.

carbinol ivanishi

Isiseko kwezi ivanishi ezi nentlaka carbinol ezifunyenwe polymerization ngezixhobo eyenziweyo - dimetilviniletinilkarbinola. Kwezi emahlamvini ayisekelwanga kuphela ukupeyinta, kodwa iglu esetyenziswa zokwakha kunye noshishino. Kubushushu degrees 20 lome eli ivanishi phezu workpieces kangangesiqingatha seyure. Kuxhomekeka ekwakhiweni, ivanishi carbinol kotywala bebala okanye enemibala.

Ivanishi yayisetyenziswa kwilaphu Imiphezulu ziinkuni

Ipeyinti Ezo ngaphaya nabanako udlulisele umphezulu isilungiseleli seglosi kwaye agxininisa iinkuni ukuguda noburhabaxa yendalo. ivanishi uMoya zokuba ziinkuni ezisetyenziswa kakhulu kwishishini ifanitshala le. Ekubeni isiseko sabo utywala ethyl, bakhawuleza yome uze ibe ukhuseleko oluthembekileyo imiphezulu baphathwa elangeni nezinto ezimbi zezulu.

okubonakalayo ekuveliseni ivanishi moya (sandarak, shellac, yaye ngoko Acaroidea. P.) Ngaba kuphela eRashiya, kodwa uvela kwamanye amazwe aphesheya. Ngaba Ipeyinti arcade games ezivela shellac kunye shellac, ezisetyenziswa ngokubanzi yokutyabeka iinkuni kunye negilasi imiphezulu. Okwangoku technology wafunda idiolom endaweni ezi nentlaka, zokwenziwa izakhi nentlaka. Sekunjalo, intlaka loo enasilela umgangatho shellac ezinxilisayo ivanishi, ayikho nje ixesha elide kwaye iyamelana ezenzeka ngaphandle. Ngaphezu koko, emahlamvini izakhi mnyama ukukhanya.

ivanishi Utywala-based ibe ziinkuni kukho umaleko obhityileyo kwaye kudala transparent umboniso. Ukuze zibeka isakhiwo phezu kweenkuni ukukhanya kufuneka isetyenziswe kuphela uchaza eziqaqambileyo.

umoya nokuvumelana ivanishi

Kuxhomekeka isixa intlaka zibandakanyiwe ekwakhiweni, ivanishi umoya zihlelwa ngokwamaqela zilandelayo:

1. Eneneni ivanishi (30% nentlaka).
2. Zokukhazimlisa (ngaphantsi kwe-30% ye-nentlaka).

Kuba unyango kumphezulu owenziwe ngamaplanga isetyenziswa advantageously turbid shellac utywala ivanishi, nto leyo nyulu ukusuka amafutha. Kuba abanye inzuzo kuba wax uyakwazi ucingo imingxunya entle kubume ngayo imiphezulu iinkuni.

Ukuze lacquer umgangatho oko olugqibeleleyo, ngelixa ukukhwezela ukuyondelelana utywala akwamkelekanga ukuba usebenzise udweliso lweenkqubo okwakhiwa kwalo yentsimbi. In yokusebenzisana isisombululo ielementi shellac uba omnyama. Ngaphezu koko, yavelisa iidipozithi ezingafunwayo engakhankanywanga kubuxhakaxhaka bokuvelisa lacquer.

kufuneka ixesha nokuveliswa zokukhazimlisa, iiyure ezi-3 ukuya ku-5. Xa eyimveliso lacquer kuthatha ixesha ngakumbi iiyure-7 ukuya kwele-9. iintsuku Okunye (iiyure ezingama-24 ukuya kwezingama-40) olufunekayo ukuze nokuveliswa ivanishi copal zamafu. Ukuze kokuxova nkqubo ngokukhawuleza, kwaye umxube itshiswa, lo gama kuqinisekiswa ibangele rhoqo isicombululo.

Olinganise izisombululo ezisisiseko nentlaka

1. Utywala-enyibilikayo ukumba (ukumba ne-60 kg 75-90 kg yotywala).
2. Shellac (40 no-65 kg, ngokulandelelanayo).
3. Rosin (60 kg 60 kg).
4. Berestovaya resin (35-40 kg 60-65 kg, ngokulandelelana).
5. Sandarac (60 kg 100 kg nganye).
6. Shellac (45 kg 90 kg).
7. Iditol (30-40 kg 60-65 kg, ngokulandelelana).

Ukuze ufumane izisombululo ezinqwenelekayo uzinzo kuluhlu ixutywe kwaye shushu kancinane. izisombululo sandarac kunye copal ezisetyenziswa ivanishi olulandelelanayo ukunyanga evele izixhobo zomculo. ivanishi Lithographic kufuneka isilungiseleli seglosi izinto kwaye ayithethi ukufunxwa ephepheni. Shellac ivanishi, yenzelwe yonyango iinkuni, anikho phantsi lokuhluza. Ukuba idlule enemingxuma ezenziwe ngobhedu. Ngenxa nyango ibonelelwa ukususwa ngomatshini le ukungcola.
