Amavuta ya tung yatetse nibyiza kandi akama vuba, ariko amavuta ya tung mbisi agomba gutekwa.Amavuta ya tung yatetse nibyiza kuvangwa na turpentine.Ibiti byo hanze ntabwo byoroshye kubora iyo wogejwe namavuta ya tung.Turpentine ihwanye na 30% yikigereranyo cyose.Turpentine ikurwa mu biti bya pinusi, kandi urugero rwo kurengera ibidukikije ni rwiza.Amavuta ya Tung ntabwo aribwa cyane nkamavuta y irangi, nyuma yo gutwikwa namavuta ya tung yatetse, hazakorwa firime ikingira hejuru yinkwi, zidafite umuyaga, bityo bikagira ingaruka zidafite amazi.Byongeye kandi, niba muri rusange amavuta ya tung ahanaguwe nigitambaro cyiza cya pamba, ntabwo yogejwe hamwe na brush, kandi umwanda uzasohoka Ingaruka ntabwo ikora.
Bikaba byiza kumavuta yo mumashanyarazi yo hanze cyangwa langi
byose ni byiza.
1. Ukurikije ibiyigize, ibikoresho fatizo byamavuta yishashara yibiti usanga ahanini ari pigment naturel, amavuta yimboga, nibindi, kandi ntabwo birimo ibintu byuburozi, mugihe amarangi arimo ibintu bimwe na bimwe bya resin, birimo ibintu byuburozi.Ku bijyanye n’imikorere, amavuta y’ibishashara yinkwi afite ibintu byiza bitarinda amazi kandi birwanya kwanduza, kwambara birwanya no kurwanya scrub, kandi birakwiriye kubakwa mu nzu no hanze, mugihe varish ifite amazi meza, ariko ntishobora gukoreshwa mubidukikije.
2. Nyuma yo gusiga irangi rya anti-cracking, hakozwe firime yuzuye irangi hejuru yibicuruzwa.Filime irangi irashobora gutandukanya ubuhehere buri mu kirere, ikagira ingaruka nziza zo kurwanya ruswa no kurwanya ruswa, kandi ifite urwego runaka rwo kurwanya kwambara.Mubyongeyeho, kubera ko irangi ryirangi rigizwe nibice bibiri kandi ririmo umubare munini wumuti ukiza, ryuma vuba.
Hanze yo kurwanya ruswa yohanagura ibiti byo gusiga ibiti cyangwa ibishashara nibyiza
Irangi rya anticorrosive yo hanze ryitwa amavuta y'ibiti.Amavuta y'ibishashara by'ibiti ni izina risanzwe mu Bushinwa ku irangi ry'amavuta y'ibimera.Ni irangi risanzwe ryibiti risa n irangi ariko ritandukanye n irangi.
Ifite ibi bikurikira:
1. Imbaraga zikomeye zinjira no gufatira hamwe, zirashobora gutanga umusaruro wa capillary hamwe nibiti kandi bigakora hamwe.
2. Igiti kirashobora guhumeka neza, kugenga ubuhehere, ubworoherane, no gutinda guhinduka.
3. Antistatike, itagira ingaruka ku mubiri w'umuntu, kandi irashobora gukumira umukungugu mwiza.
4. Shyira ahagaragara imiterere karemano yinkwi.
5. Gusubiramo neza no kubungabunga byoroshye.
6. Impumuro nziza nyuma yo gukama.
Amavuta yinkwi ni meza cyangwa langi nziza?
Amavuta yimbaho ni ubwoko bwibiti bisanzwe bisa nkibara ariko bitandukanye n irangi.Ibikoresho bigizwe ahanini namavuta atunganijwe neza, ibishashara nandi mavuta yimboga karemano, ibishashara byibimera nibindi bintu bisanzwe.Varnish, izwi kandi nka varnish, ni igipfundikizo kigizwe na resin nkibintu nyamukuru bikora firime hamwe nigishishwa.
Ni ubuhe bwoko bw'irangi bwiza kubiti byo hanze?
Nibyiza gukoresha lacquer yimbaho kubushinwa, bitewe nintego ya firimu yubushinwa.
Irangi ry'ibiti bivuga ubwoko bw'irangi rya resin rikoreshwa ku bicuruzwa, harimo polyester, irangi rya polyurethane, n'ibindi, bishobora kugabanywa mu mazi ashingiye ku mavuta.Ukurikije gloss, irashobora kugabanywamo gloss nyinshi, igice cya matte na matte.Ukurikije porogaramu, irashobora kugabanywamo irangi ryibikoresho, irangi hasi nibindi.
Irangi rishingiye kumazi ni irangi rikoresha amazi nkururimi.Irangi rishingiye ku mazi ririmo amarangi ashonga amazi, amarangi avanze n'amazi, hamwe n'amabara atandukanya amazi (amarangi ya latex).Igikorwa cyo gukora irangi ryamazi ashingiye kumazi nuburyo bworoshye bwo kuvanga umubiri.Irangi rishingiye ku mazi rikoresha amazi nk'igishishwa nta guhindagurika kwangiza.Kuri ubu ni irangi ryizewe kandi ryangiza ibidukikije.
Nitro varnish ni ubwoko bwirangi ryeruye ryateguwe na nitrocellulose, resin ya alkyd, plastike hamwe na solge organic.Ni irangi rihindagurika kandi rifite ibiranga gukama vuba kandi byoroshye.Vitish ya Nitro igabanijwemo ubwoko butatu: gloss ndende, igice cya matte na matte, bishobora gutoranywa ukurikije ibikenewe.Nacro lacquer nayo ifite ibibi byayo: ikunda kwera mugihe cyubushyuhe bwinshi, ubwuzure buke, nubukomere buke.
Fungura
Irangi rya polyester ni ubwoko bw'irangi ryimbitse rikozwe muri polyester resin nka firime nkuru yambere.Irangi ryerekana irangi rya polyester ni pompe, umubyimba kandi urakomeye.Irangi rya polyester kandi rifite ubwoko butandukanye, bita polyester varnish.
Irangi rya polyurethane ni irangi rya polyurethane.Ifite firime ikomeye, irangi ryinshi, gufatana gukomeye, kurwanya amazi, kurwanya kwambara no kurwanya ruswa.Ikoreshwa cyane mubikoresho byo murwego rwohejuru rwibiti kandi birashobora no gukoreshwa hejuru yicyuma.Ibibura byayo bikubiyemo ahanini ibibazo nko guhura nifuro itose, gusiga amarangi ya firime, kimwe n irangi rya polyester, irahari kandi ikibazo cyo guhinduka umuhondo.Ubwoko bwa varish butandukanye bwa polyurethane bwitwa polyurethane varnish.Umuvuduko wo gukiza wibicuruzwa urihuta, mubisanzwe birashobora gukira no gukama mumasegonda 3-5.Igicuruzwa ntabwo kirimo fordehide, benzene na TDI, kandi rwose ni icyatsi kandi cyangiza ibidukikije.Uburyo bwubwubatsi burimo: gutera, guswera, gutwikisha uruziga, guswera, nibindi.Mubyongeyeho, kubera ibintu bikomeye bihamye, ubwuzuzanye ntaho buhuriye nandi marangi rusange.Ikibi nuko bisaba ibikoresho byumwuga kugirango bikire.
Niki gusiga irangi hanze
Ibiti birwanya ruswa bikenera irangi, kandi irangi ryo kurwanya ruswa rishobora gukoreshwa.Muri rusange, nyuma yo guterwa no kubungabunga CCA, ibiti bizaba umuhondo-icyatsi, na nyuma yo kuvura ACQ, bizaba icyatsi.Igiti cyo kurwanya ruswa ubwacyo gifite imikorere yo kurwanya ruswa.Urebye ibiti birwanya ruswa, nta mpamvu yo gukoresha amarangi yose, ariko ibiti bikomeye birakoreshwa hanze igihe kinini, kandi ibara ryacyo rihinduka buhoro buhoro umukara-umukara mu myaka 2-3 kubera imirasire ya ultraviolet .Kuri iri bara rihindura ibiti, irangi ryibiti byo hanze rishobora gukoreshwa kugirango wongere firime ikingira hejuru yinkwi kugirango igere ku mazi adashobora gukoreshwa n’amazi, kurwanya ifuro, kurwanya ibishishwa ndetse no kurwanya UV.
