Irangi rirwanya ingese

Irangi rirwanya ingese ni ubwoko bw'ibintu bigira uruhare mu kurwanya ingese, bikarinda ingese mu byuma kandi bikongera ingaruka zo kurinda irangi ku buso bw'icyuma. Uruhare rw'irangi rirwanya ingese rushobora kugabanywamo ibice bibiri: irangi rirwanya ingese mu buryo bw'umubiri n'iryangiza ingese mu buryo bw'imiti, aho irangi rirwanya ingese mu buryo bw'imiti rishobora kugabanywamo ibice bibiri: irangi rirwanya ingese mu buryo bw'imiti rishobora kugabanywamo uburyo bwo gukumira ingese n'uburyo bwa kabiri bwo kurwanya ingese mu buryo bw'amashanyarazi. Ibintu bigira uruhare mu gukumira ingese birimo ifu y'umutuku w'ibara ry'umutuku w'icyuma, ifu ya titaniyumu y'icyuma ivanze, ifu ya zinki ya aluminium tripolyphosphate n'ibindi. Kuri ubu, irangi rirwanya ingese rikoreshwa cyane cyane mu gusiga irangi rirwanya ingese, kandi ikiguzi cy'irangi rirwanya ingese gingana na 6%-8.5%.

Itandukaniro riri hagati y'irangi rirwanya ingese n'irangi ni irihe?

Irangi rirwanya ingese ni ubwoko bw'irangi rishobora kurinda ubuso bw'icyuma kwangirika kw'ibinyabutabire cyangwa amashanyarazi mu kirere, amazi yo mu nyanja, n'ibindi. Irangi rikoreshwa mu buryo bufatika n'ubutabire rirwanya ingese, nk'umutuku w'icyuma, ifu ya aluminiyumu, irangi rya grafiti rirwanya ingese, icyuma gitukura, irangi ry'umuhondo wa zinc rirwanya ingese n'ibindi.

Irangi ni irangi rivanze n'imiti ritwikira neza ubuso bw'ibintu, rikarinda, rikaryoshya, rikagaragaza n'ibindi bikorwa byihariye, kandi rigakora agace gakomeye gafata neza ubuso bw'ibintu kandi gafite imbaraga runaka kandi gahoraho.

1. Imirimo itandukanye:

Irangi rirwanya ingese rifite imiterere yo kurwanya ingese no kurwanya ingese, firime irakomeye, ifite imikorere myiza cyane, kandi ubukana bwayo buri hejuru y’irangi risanzwe. Irangi risanzwe nta mikorere yaryo yo kurwanya ingese, kuko ibikoresho bisanzwe by’irangi ari alkyd resin, binyuze mu gushonga no kuma, ubukana buke, n’icyuho cy’urwego rwo gufatana.

2. Ubuzima butandukanye bwa serivisi:

Irangi rirwanya ingese rishobora gukoreshwa mu gihe cy'imyaka 5-8 mu gihe rihuye. Irangi risanzwe rikunze gukoreshwa hanze mu gihe cy'imyaka 3. Nyuma y'imyaka ibiri cyangwa itatu, biroroshye kugwa, gushonga no gushonga.

3. Ubwoko butandukanye:

Irangi rirwanya ingese: irangi rya phenolic rirwanya ingese, irangi rirwanya ingese rya alkyd (umutuku w'icyuma, imvi, icyuma gitukura), irangi rirwanya ingese rya chlorine, irangi rya epoxy rirwanya ingese (irangi rirwanya ingese rya zinc phosphate, irangi ritukura rirwanya ingese, irangi rirwanya ingese rikungahaye kuri zinc, irangi ritukura rirwanya ingese rya icyuma), nibindi

Irangi: Ubwoko bwinshi bw'irangi, irangi rirwanya ingese naryo ni ubwoko bw'irangi, usibye irangi rikubiyemo irangi ry'ibiti, irangi ryo hasi, irangi ryo hanze ku nkuta, irangi ry'amabuye, irangi ry'amabara menshi, irangi rya aluminiyumu, irangi ririnda umuriro, irangi rya latex n'ibindi.

Ibyerekezo umunani by'iterambere ry'irangi rirwanya ingese mu gihe kizaza

Ubwa mbere, guteza imbere irangi rikoreshwa mu mazi rirwanya ingese n'irangi ryo hejuru ku nyubako z'icyuma.

Igikoresho cyo kurwanya ingese gishingiye ku mazi kigomba gukemura ikibazo cy’ingufu za "flash rust" hamwe no kudakomera kw’amazi, kandi kwiyongera kwa emulsifier nshya zidafite emulsifier byatumye izina ryayo ridakomera ry’amazi, kandi ahazaza hagomba kwibanda ku gukemura ibibazo by’imikorere y’ubwubatsi n’imikorere y’ikoreshwa. Nk’igitambaro cyo hejuru, ahanini ni ukunoza imitako no kuramba kwayo mu gihe cyo kwemeza ko ikora neza.

Icya kabiri ni ugukora urukurikirane rw'irangi rikomeye kandi rirwanya ingese ridafite ibinyabutabire.

Gucukura, urubuga rwo mu mazi n'imishinga minini yo kurwanya ingese mu rwego rwo kuramba cyane mu bijyanye no kurwanya ingese, ni ibintu byihutirwa cyane, isoko ririho ubu ahanini ni ibigo by'abanyamahanga n'ibicuruzwa bitumizwa mu mahanga byigaruriwe. Ibicuruzwa by'Ubushinwa biri mu rwego rwa tekiniki, imbaraga z'ubukungu, sisitemu yo kwemeza ubuziranenge n'izina ry'ibicuruzwa ndetse n'ikindi kinyuranyo cy'imbaraga n'ibihugu by'amahanga, biragoye kwinjira ku isoko. Kugira ngo ibyo bigerweho, mbere ya byose, hagomba gushyirwa imbaraga mu iterambere rya tekiniki, cyane cyane iterambere rya primer irwanya ingese idafite lisansi kandi idafite chromium, ni ukuvuga ishingiye kuri primer irwanya ingese ya zinc phosphate na aluminium tripolyphosphate.

Icya gatatu ni ugukora primer ikungahaye kuri zinc ishingiye ku mazi.

Ibumba rikungahaye kuri zinc idafite umwimerere n'ibumba rikungahaye kuri zinc idafite umwimerere ridafite umwimerere ni bimwe mu bikoresho bimara igihe kirekire, ariko ni ibikoresho bidafite umwimerere. Ibumba rikungahaye kuri zinc idafite umwimerere ridafite umwimerere ridafite imiterere ihagije rifite modulus potassium silicate nk'ibikoresho by'ibanze ni ibumba ririnda ingese rikora neza ryapimwe n'ibikorwa kandi rifite ubushobozi bwo gukura.

Icya kane ni iterambere ry'icyuma gihindura ubushyuhe gikingira ubushyuhe kirwanya ingese.

Utwuma duhindura ubushyuhe dukeneye irangi rirwanya ingese rifite ubushyuhe bwinshi kandi rishobora gutwara ubushyuhe bwinshi, kandi irangi rya epoxy amino rikoreshwa ubu rigomba kuvurwa kuri dogere selisiyusi 120 kandi rigasaba irangi ryinshi, ridashobora gukoreshwa ku bikoresho binini.

Icya gatanu ni ugukora irangi rishobora kuvurwa ku bushyuhe bw'icyumba kandi ryoroshye kurishyira.

Ingingo y'ingenzi ni ukubona uburyo bwiza bwo kwirinda ingese, uburyo bwo kohereza ubushyuhe n'uburyo bwo kubaka irangi.

Icya gatandatu ni iterambere ry'ingufu zirinda ingese.

Okiside y'icyuma ya Mica (MIO) ifite ubushobozi bwo kurwanya amashanyarazi, kurwanya gusaza kw'ikirere no gukumira, kandi ikoreshwa cyane nk'irangi rya primer n'iry'inyuma mu Burayi bw'Iburengerazuba.

Icya karindwi, guteza imbere urukurikirane rw'ibikoresho birwanya ingese bikoreshwa mu gusiga irangi mu buryo bwa chlorine.

Kubera ko peteroli irimo chlorine ari igice kimwe, imiterere yayo yoroshye, irwanya amazi, irwanya peteroli, irwanya gusaza mu kirere ni nziza cyane, ikoreshwa cyane mu kubaka amato, gukumira ingese mu nganda no mu zindi nzego, hari isoko rinini mu Bushinwa. Ariko, kubera ko ikorwa rya peteroli irimo chlorine rikoresha CC1 nk'umusemburo, urwego rwa ozone rurangirika.

Icya munani ni uguteza imbere ibikoresho byo gukumira ingese byahinduwe mu buryo bw'umwimerere.

Mu myaka ya vuba aha, ikoreshwa rya sima yahinduwe na emulsion y’umwimerere kugira ngo yongere imbaraga zayo, ikanahangana n’ubudahangarwa, ikoreshwa cyane mu gusiga hasi mu nganda. Muri zo, emulsion y’amazi ya epoxy (cyangwa epoxy ishingiye ku binyabutabire) irimo gutera imbere vuba cyane, yitwa sima ya polymer.

Ibyerekeye twe

Isosiyete yacukuva kera yakomeje gukurikiza ""ubumenyi n'ikoranabuhanga, mbere ya byose, ubunyangamugayo n'ubwizerwe, gushyira mu bikorwa gahunda mpuzamahanga yo gucunga ubuziranenge ya ls0900l:.2000. Dufite ikoranabuhanga rihamye, dutanga serivisi nziza, twatsindiye kumenyekana ku bakoresha benshi.Nk'umwuga, uruganda rukomeye kandi rusanzwe rw'Abashinwa, dushobora gutanga ingero ku bakiriya bashaka kugura, niba ukeneye irangi rirwanya ingese, twandikire.
