Kettle varnish - ea kajeno ke qete tse bonahalang

Ntshetsopeleng ya theknoloji e morao-rao bakeng sa tlhahiso ea thepa e qete dumella ho hlahisa bohle ba o khathollang le tse ncha dihlahiswa le a 'maloa a thepa e ikhethang. novelties joalo e sebetsa kettle lacquer.

boitsebiso boo e emela ka ditharollo fapaneng bophara isocyanates hydroxyl polyfunctional. Kettle lacquer ha sebelisoa liforomo holim'a polymer tiileng le sebopeho a mararo-tlhakore. Tshebetso ena e hlaha ka lebaka la ho ba itšoara joang ea isocyanates le dikarolo hydroxyl (fella polyesters fumanoa ka ho ikutloa ka tsela e feteletseng ea joala polyhydric le asiti e dibasic kapa le metsoako ea monobasic le dibasic mafura acid).

Atisa ho sebelisa le mokhoa o sa fellang hydrolyzed polyvinyl acetates, polyacetals fella, selulose esters, le phenol-formaldehyde lehoakhoa ksilolformaldegidnye. Har'a isocyanates sebediswa ho fetisisa e atisa ho sebelisoa diisocyanate le metsoako e sa tšoaneng lona. Hape, sebelisa hexamethylene diisocyanate le lihlahisoa itsoara joang ka ea diisocyanate feteletseng le ka ho noa joala polyhydric le hydroxyl nang polyesters. Ho sebetsa ka thepa tsena hloka mehato e khethehileng. Ke ka lebaka leo ho le molemo ho sebelisa "thibetsoeng" kapa "a patiloeng" isocyanates, metsoako tse habonolo bole ha halefile. sehlopha sena se akarelletsa lihlahisoa itsoara joang ka ea isocyanates le malonic, acetoacetic Ester, ethyleneimine le feniluretanom. Kettle lacquers qhibiliha sebelisa esters, ketones, ditlelorine hydrocarbons, nitroparaffins. Tsena lisebelisoa diluent ke xylene, toluene, aliphatic hydrocarbon.

Kettle lacquers tse fumanehang e le e mong-karolo kapa tse peli-motsoako o hlophisitsoeng. Tabeng ea bobeli ka thoko lokisetsa tharollo ya metsoako hydroxyl-e nang le, kapa metsoako ea metsoako tsena le tharollo isocyanate pele ho sebelisa moemeli ena ba tsoakileng. Joalo e lokisitsoeng peli karolo lacquer bolokiloe ho tloha lihora tse 4 ho ea ho 48. coatings joalo li sebelisoa bakeng sa ho barbotage ea chesang le a batang a phekola. Se nang moeli ho nkoa tsitsitseng mong motsoako chesang-phekola coatings entsoeng ka lebaka la seo ho thoeng ke "thibetsoeng" isocyanates.

Kettle varnish bopa e benyang, coatings rekere le thatafala phahameng, mamarello molemo, phahameng thepa dielectric le ho hanyetsa lik'hemik'hale. Di ka ho eketsehileng a ntse a sebelisitsoe bakeng sa ho sireletsa le konkreite, tšepe, bokaholimo lehong le e sebediswa bakeng sa ho penta le thepa ea lik'hemik'hale, qhibilihisa le hloekisoa dimela, ka likhoebo lijo.

Fumaneha kettle varnish bakeng parquet, thepa ea ka tlung, rabara, pampiri, letlalo, meaho sesole sa metsing, masela a maiketsetso a le dipolasetiki. barbotage Sena ke tsoarellang haholo le e sebetsang, e haholo eketsa raka, athe bophelo ea thepa e sa tšoaneng. A le mong-karolo coatings ba atisa ho sebediswa bakeng sa ho sireletsa koporo, aluminium le tšepe lihlahisoa.

Varnish kettle metsi ho sireletsa mabota lehong le siling ea hlobo le hlobo. Ke haholo khanya le mocheso manganga. This barbotage bonaletsang lumella ka ho phethahetseng totobatsa botle ba tlhaho tsa lehong.
