Latex ngopende kanye izici zalo ukusetshenziswa

Painting ingenye yezindlela jikelele ukuvikela izakhiwo kanye nezinhlaka emathonyeni asemkhathini ezifana ilanga, umoya, ukushisa kanye kwezulu. Coloured ungqimba ahlangabezane umthwalo okarisako zici ezingenhla. Ukuze ukucabanga umthelela izimo zezulu, cabanga nje izizathu ukubhujiswa ezintabeni kanye kumiswa emihumeni. Lokhu kufakazelwa iqiniso lokuthi ilanga siyimbangela ukuzamazamisa i-Eiffel Tower ...

Kukhethwa imibala kuyisinyathelo ebaluleke kakhulu imisebenzi imidwebo. Ngenxa izici eziningi incike izinga layo. Kubalulekile futhi ukuba ukhumbule ukuthi, kungakhathaliseki ukuthi yini upende ukhethe, ukuvikeleka ngokuphelele uthola. Futhi uma umninindlu wayethi okuphambene, uzowathola ukuthola kangcono kwenye inkosi. Kodwa namanje, ngcono enamathela, isikhathi eside into ngesineke. Upende kuhle kakhulu ukuba uwuthenge kusuka umthengisi. Naphezu amanani aphezulu, wena ukuthathelwa umshuwalense ukuze umelane mbumbulu.

Ngakho, uya ukupenda indlu. Yini upende ukukhetha? Uma ikhaya lakho ongelona ukhuni, ukhetho best - latex upende. It ihlukile amafomu yendabuko wukuthi ukwakheka kwalesi Indwangu siqukethe izingxenye ezimbili immiscible: globules (ngomzuzu ezinemibala izinhlayiya) kanye emulsifier (uketshezi lapho okuhlala ziyoncibilika globules). Okungukuthi, ewumgogodla latex upende - kuba i emulsion, nezinhlayiya okwathi ukuxuba, lihamba emoyeni. Ngakho-ke, upende ngaphambi kokusebenzisa kubalulekile nokuzamazama kuvuse ngezikhathi ezithile ngesikhatsi kokuhlinzwa. Umgomo we operation wukuthi uma isetshenziswa ebusweni ejenti emulsifying ihlangana emoyeni; ngenxa ye-ezikhishwe amanzi izenzo phezu futhi ehwamukile; Kumiswa phezu ifilimu esobala i emulsifier, lapho izinhlayiya anemibala kuthiwa nombala basakaza. Kuye izinhlayiya umbala etholwe ebusweni ngesineke elihambisana umbala.

Latex upende kungaba ezimbili zama:

1) polyvinyl acetate - kakhulu ziphoqa. Ngaphezu amanzi, upende latex okunjalo adhesion ngokwanele ezinhle ukhonkolo kanye usimende evele. Ungakwazi alisibekele nomuthi, kodwa hhayi efiselekayo (kungani - bona ngezansi).

2) acrylate amanzi ukuhlakazwa - lokhu upende has okusezingeni eliphezulu sezulu ukumelana. Njengomthetho, isetshenziselwa umbala we mbumbulu zezakhiwo, kanye izindawo nomswakama eliphezulu. Ukusetshenziswa Its kwenza kube nokwenzeka ukuba afeze eliphezulu kakhulu izinga yokuqedela of izakhiwo. Asihambisani ukhuni evele.

Latex, latex upende kunenhloso efanayo. Kungenzeka beyomboza eziphathekako usimende. Kodwa metal nezinkuni kungcono okumelwe lishumayele kuyo. Lapho yokudweba izindawo aphuzi zingavela izakhiwo ngokhuni - ngokunembile ngenxa adhesion ezinhle kakhulu izinkuni. On metal njengoba latex upende, intengo iphansi ngokwanele, kugcina kabi kakhulu, esikhathini esifushane ehlutshiwe yithela.
