Lezi izinto ezisetshenziswa kulezo zimboni. Inhloso esemqoka - kuyinto lokuvikeleka kwezifiso ezisemqoka ezingumphumela evele futhi izingxenye kusukela umswakama noma nezinye izinto ezonakalisayo. Asetshenziswa ngenxa yokudweba igesi amathangi. Bakelite varnishes njengabakhulu kunani nezinye izinhlobo imikhiqizo ukusebenza yayo, ngoba asetshenziselwa bakhulelisa futhi gluing izingxenye ahlukene imininingwane.

The njalo kunazo ziphathwe izingoma ezifana wadalula ipulangwe. Bakelite ukuvenisha izici lobuchwepheshe njengoba kuchazwe esihlokweni, isetshenziswa hhayi kuphela ukwakhiwa kodwa nakwezinye izimboni. Phakathi kwabo kukhona lokhu okulandelayo:

• Shipbuilding - ukukhiqizwa sigxumele phezulu emikhunjini kanye yezikebhe;
• embonini yezimoto - ukukhiqizwa ikhava aphansi, kanye izingxenye ngabanye;
• ukwakhiwa - flooring, umhlobiso Ingaphandle zezakhiwo, uphahla, amakamelo umhlobiso futhi ifenisha yokukhiqiza;
• womshini izibhamu izindawo zemidlalo;
• womshini imikhiqizo zezingane, nokuningi.

Inqubo yokuthola ukuvenisha

Ukuze sikhiqize Ukwakheka ezinjalo, izinto ezilandelayo kumele kusetshenziswe: phenol, ETHYL utshwala, formalin kanye ammonia. Yiziphi izici bakelite lacquer siyazi? Bona ancike izici izingxenye ephambili.

Izimpawu izinto ephambili

Ngakho, yinto yokuqala - a phenol. Kuyinto kwakwakhe organic okuyinto ancibilikisa nabo amanzi. lokushisa yayo okokuqandisa kuyinto 40 ° C. Formalin - lena izinto eziyingozi anobuthi, okuyinto kubhekwa ushevu. Kuyinto ketshezi kokuba ezingeni eliphansi reactivity. Ammonia alisetshenziswa ifomu okumsulwa kodwa wenziwe isixazululo ezibuthakathaka aqueous.

ETHYL utshwala isetshenziselwa uzotshala carbon equkethe izinto. Umphumela wokugcina uketshezi esicacile. Singasho zipendwe ngemibala ehlukile. Futhi e lacquer kuhlanganisa amafutha yemifino kanye cellulose. Ngaphambi kokunezela sidlule ukwelashwa olunzulu.

Izinhlobo ezinkulu

Namuhla kukhona 9 izinhlobo ezinkulu lacquers bakelite. Ngamunye wabo isetshenziswa umkhakha othize. Ngaphezu kwalokho, banayo amaphesenti ezahlukene izinto ephambili, isb phenol, formaldehyde, Ethanol kanye ammonia. Nge ushintsho inani omunye izinkomba ukuthi ushintshe izakhiwo ukuvenisha kanye nokwenza imisebenzi yayo. Ngokwesibonelo, singaqhathanisa brand varnishes ezifana:

• SBS-1 - ukubhekisiswa plastic kanye ipulangwe, ezisetshenziswa umhlobiso yangaphandle futhi ingaphakathi endlini.
• LBS-4 - sepulasitiki ahlukahlukene equkethe fillers amaminerali.
• LBS-1 kanye LBS-2 - kubhekwa varnishes bakelite eliphezulu kakhulu futhi asetshenziselwa i-enamathela of epulasitikini futhi izihloko steklotekstilnyh.

I ukuvenisha isetshenziswa ebusweni yokwakha izinto noma izingxenye nge ibhulashi noma roller. Kumiswa yi lokugcina phezu ifilimu okhethekile kwala maphuzu organic noma wezinto ezingaphili. Kuvikela ebusweni kusukela umswakama kanye nezinye izinto ezonakalisayo.

Ukusebenzisa ukulungisa

Lolu hlobo lacquer isetshenziselwa kokubili imisebenzi ngaphakathi kanye nabangaphandle. Ngosizo udayi ekhethekile kungenzeka ukufeza umbala oyifunayo komkhiqizo. Izakhiwo ukuvenisha zihlala zinjalo. Nokho, ukusebenzisa kwayo ekhaya luyindida. Ngaphambi kokufaka isicelo ebusweni zigezwe zezinsimbi ngokweqile bese boma it. Ngemva enamathela, ebusweni ukuvenisha kumele ukushisa ngayo. Amazinga kufanele sifinyelele 160 ° C. Ukuze kuzuzwe lokhu kuyodingeka wenze.

omiswe Yemvelo wenziwa phezu kwamanzi 4 amahora. Ukuze uthole ukuvikeleka ngokuphelele sisetshenziswa phezu ungqimba yesibili equkethe yamathebhu ethize. Konke lokhu okulandelayo gcwalisiwe. Ekugcineni, ukushuba ifilimu ifinyelela 0.5 mm.

Ukuze uthuthukise amandla mechanical ebusweni isetshenziswa ukotini Indwangu ukuthi ukuba afuthwe ngesibulali bakelite ukuvenisha. It ibekwe 3 ungqimba. Lobu buchwepheshe simiswe ngalendlela lelandzelako: Indwangu lokuqala kufanele kahle wageza ukuqeda isitashi.

It is uthathe imigoqo encane bacwilisa esitsheni kapende. Kufanele cwilisa amaminithi awu 5. Ngaphezu kwalokho, izicubu asuswe esitsheni nokusetshenziswa iraba amagilavu wring. Izingcezu elifakwe sikhuthazele emoyeni ongaphandle kanye omisiwe, ukuze khona kuphela lincishisiwe. Indwangu primed sisetshenziswa yomiswa phezu futhi phezu nge ibhulashi isicelo lacquer. Uma kuba khona isidingo ukwandisa amandla mechanical igemfe, ndwangu uthathe isiqeshana of ububanzi ezincane. Inqubo ke wakhamba naye emigqeni efanayo.

Ekugcineni kwakhiwa ifilimu is phezu ukwakhiwa, okuzokwenza ukuvikela impahla nokusondelana umswakama kanye nezinye izinto. Kungase kungalimala ngaphansi kwezimo eziningana:

• uma engaphezu kwengu-20 ° C izinga lokushisa ziyokhinyabezeka isikhathi eside;
• uma ebusweni camera nge-lacquer, uthole elangeni.

Naphezu kweqiniso lokuthi ukukhanda of bakelite ukuvenisha kubangela ebunzimeni obuthile, ukwahlulela nge izibuyekezo abathengi, la mabhodi ehlala zithandwa kakhulu.

inqubomgomo zamanani

Isakhiwo izindleko ngezindlela ezihlukahlukene, kuye sha, kanye ukusetshenziswa isikhala. Inani ukwakhiwa enjalo uhla kusuka cents ilitha 300 1000.

isiphetho

Njengoba Bathi inkosi, ukuvenisha bakelite sisetshenziselwa izinto ezithandwayo esetshenziswa hhayi kuphela umkhakha, kodwa futhi ekuphileni kwansuku zonke. Isetshenziselwa ukukhiqizwa kwamakhemikhali ahlukahlukene kanye izinto. Abantu abasebenzisa kubo, bathi ubuchwepheshe isicelo salo kahle elula. Bathi nje ukugcizelela ukuthi imithetho ethile okufanele zilandelwe uma usebenza ngopende. Le ndawo lokuqala namabala kufanele kahle umoya. Akukwazi eside, njengoba ushintsha uba yileli evala of phenol phambili ubuthi.

Ngakho, sathola ukuthi lena ingxenye, futhi sathola ukuthi kungakanani esikwazi izimfanelo bakelite lacquer.
