Utshwala ukuvenisha zibe yizinkuni

Ububanzi upende owenziwe ngesisekelo utshwala, kuhle ezibanzi. Ikakhulu, i-umkhakha Iyakwazi ukukhiqizwa upende enamathela impahla imikhiqizo ehlukahlukene:

• Interiors kanye mbumbulu sobukhulu bezakhiwo;
• ifenisha;
• ingilazi evele;
• izihloko eyenziwe lesikhumba;
• amakhabethe nokunye ngomuthi.

Ngenxa yokuthi esikhathini ukuvenisha kuyinto resin ziyoncibilika utshwala, isikhathi esigcwele omiswe akuyona ngaphezu kwesigamu sehora. Ngakho, utshwala ngokuthi varnishes, etholwe Ukuqedwa inhlaka zemvelo otshwaleni. Ochwepheshe iphuzu uma beveza ukuthi yibo abathole ezinengilazi ziphezulu ukusebenza futhi ngenxa yobuhle izakhiwo:

• eside service yokuphila;
• amandla ngemishini;
• kakhulu ukumelana kwelanga;
• akhanye enhle.

Ngesisekelo utshwala yilezi: Shellac, rosin futhi carbinol varnishes.

Shellac ukuvenisha ku isizinda utshwala

Shellac - uhlobo izinto okhipha inhlaka izitshalo, linqoba ezindaweni ezishisayo nakwezifudumele. Njengamanje, liye kabanzi womshini varnishes futhi Plastics. Ngenxa izakhiwo zayo eziyingqayizivele kahle uyakwazi Shellac ziyoncibilika utshwala. Resin ngokushesha ngangokunokwenzeka futhi encibilikayo ngaphezulu, it is kahle kutsho ukuthola powder mass esihle. Ngokulandelayo, powder etholakala ixutshwe 92-95 angu-ethanol. Ukuncibilikisa ngokuphelele resin ingxube ngokwanele sekuqala ukufudumala kuze kube degrees 20, ngezikhathi shaking ingxube okuholela. Utshwala ngaleyo ndlela etholakalayo ngokusebenzisa resin ukuvenisha ukuba isihlungi ezinhle ukuqeda inclusions zingaxazululeki futhi akhiphe amanyela. Njengoba izihlungi olusetshenziswe Kulokhu ingilazi uphondo ayihlomele strainer ezivamile indwangu. Okuqukethwe iphesenti Shellac izixazululo ezinjalo zokhahlamba kusuka 30 kuya kumaphesenti angu-45.

Alcoholic Shellac ukuvenisha unika enamathela ngokwanele ezinzima, amelana ukukhanya, kodwa awukwazi ukumelana nokushintshashintsha kwezinga lokushisa nokuchayeka amanzi.

rosin ukuvenisha

Njengesisekelo upende babesebenzisa rosin. It - yemifino gum, ethathwe ekwelapheni zikaphayini izinkuni. Ukungaguquguquki rosin ukuvenisha simiswe ngalendlela lelandzelako:

• 110 g rosin;
• 20 g we turpentine;
• 20 g we turpentine;
• 80 g 95% utshwala.

Kuyaphawuleka ukuthi rosin okungukuthi hhayi kuphela isisekelo ukuvenisha. It okungukuthi ngempumelelo ukusetshenziswa njengendlela base impahla enkulu ekwakhekeni mastics.

Rosin utshwala ukuvenisha has a ongaphakeme izindleko, kodwa okungukuthi ezahlukene enamathela amandla.

carbinol ukuvenisha

Ngesisekelo lezi varnishes kukhona inhlaka carbinol etholwe polymerization zokwenziwa impahla - dimetilviniletinilkarbinola. Kulezi inhlaka akuzona kuphela ukupenda, kodwa glue esetshenziswa uma kwakhiwa noma umkhakha. At lokushisa 20 degrees uDries lokhu ukuvenisha phezu workpieces ngoba nengxenye ihora. Kuye Ukwakheka, carbinol utshwala ukuvenisha kuyinto anemibala noma kungekho nto enemibala emihle.

Varnishes esetshenziselwa ukwelapha evele lokhuni

Okunjalo ezinengilazi asobala kanye bakwazi Sinike ebusweni akhanye futhi ugcizelele zemvelo ukuthungwa izinkuni. UMoya varnishes zibe yizinkuni kabanzi embonini ifenisha. Njengoba isisekelo yabo utshwala ETHYL, basheshe zome bese isivikelo onokwethenjelwa evele iphathwa elangeni futhi izici ezimbi zezulu.

Izinto zokusetshenziswa ukwenziwa varnishes umoya (sandarak, Shellac, nokunye Acaroidea. P.) Ingabe hhayi kuphela e-Russia, kodwa futhi amazwe ezazivela ngaphandle. Yibani the best quality ezinengilazi etholakala Shellac futhi Shellac, okuyinto kabanzi ngoba enamathela ukhuni ingilazi evele. Okwamanje ubuchwepheshe wafunda idiolom esikhundleni salezi inhlaka, zokwenziwa phenolic resin. Noma kunjalo, resin enjalo zingaphansi ngekhwalithi Shellac oludakayo ukuvenisha, akusiyo njengoba isikhathi eside futhi ukumelana ezintweni ezenzeka ngaphandle. Ngaphezu kwalokho, phenolic inhlaka mnyama ukukhanya.

ukuvenisha Utshwala-based ukhuni amanga ungqimba mncane futhi kudala ifilimu okusobala. Ukuze igcizelele isakhiwo phezu kwezinkuni ukukhanya kumele kusetshenziswe upende elikhanyayo kuphela.

umoya Ukungaguquguquki varnishes

Kuye inani resin zazihlanganisa lichaza ekwakheni, umoya varnishes zihlukaniswa okulandelayo amaqembu:

1. Empeleni varnishes (30% resin).
2. Polishes (ngaphansi kuka-30% we resin).

Ukuze ekwelapheni evele lokhuni isetshenziswa advantageously turbid utshwala Shellac ukuvenisha, okungasekelwe nahlanza kusukela wax. Kuyinto ngisho inzuzo ethile ngoba wax uyakwazi clog izimbobo ezinhle isakhiwo evele lokhuni.

Ukuze izinga lacquer kwaba nasici, kuyilapho ibangele ukuvumelana utshwala akakwamukeli ukusebenzisa izingxenye lichaza ekwakheni okuyinto yensimbi. Esikhathini nokuxhumana ukuthi isixazululo isici Shellac iba abamnyama. Ngaphezu kwalokho, yathela ezifakwa engadingeki engamboziwe ubuchwepheshe ukukhiqizwa lacquers.

edingekayo Isikhathi ukwenziwa lacquers, ezisukela 3 kuya amahora 5. Ngo womshini lacquer kuthatha isikhathi esengeziwe amahora 7 kuya ku-9. Okuningi izinsuku (24 kuya ku-40 amahora) edingekayo womshini obukhulu copal varnishes. Ukuze nomkhombe nqubo ngokushesha, futhi ingxube evuthayo, ngenkathi iqinisekisa eshukumisayo njalo yesixazululo.

Wacondza isitokwe izixazululo of inhlaka

1. Utshwala-encibilikayo yokumba (yokumba futhi 60 kg 75-90 kg utshwala).
2. Shellac (40 futhi 65 kg, ngokulandelana).
3. Rosin (kg 60 60 kg).
4. Berestovaya resin (35-40 kg 60-65 kg, ngokulandelana).
5. Sandarac (60 kg 100 kg).
6. Shellac (45 kg 90 kg).
7. Iditol (30-40 kg 60-65 kg, ngokulandelana).

Ukuze uthole i-ofiselekayo ukungaguquguquki esohlwini izixazululo ngokuphelele exubile bese kancane eshubile. sandarac izixazululo futhi copal olusetshenziswe ungeno ekubhaleni varnishes ukwelashwa evele of zomculo. varnishes ungeno ekubhaleni Kumele unikeze isicwebezelisi materials kusetshenzwe futhi engenzi cwilisa singene ephepheni. Shellac ukuvenisha, senzelwe ekwelapheni ukhuni, awekho ngaphansi zokuhlunga. Badabula anezikhala wazenza ngethusi. Ngenxa yalokho zale ndlela yokwelapha inikezwa yi ukususwa mechanical ukungcola.
