Itandukaniro riri hagati y'irangi rya Epoxy na Polyurethane hasi

Irangi ryo hasi rya Epoxy vs. Polyurethane: Isesengura ryimbitse ry'itandukaniro ryabyo no guhitamo irikwiye

Tunyura mu magorofa agezweho y’inganda, mu maduka manini, no mu magaraje yo munsi y’ubutaka, akenshi ntitunyura kuri sima isanzwe ahubwo dukandagira ku gitambaro cyihariye, gisesuye kandi gifite amabara menshi. Iyi ni ingaruka z’irangi ryo hasi. Mu mahitamo menshi,irangi rya epoxy na polyurethane hasikwigarurira isoko. Iyi nkuru izasuzuma witonze itandukaniro riri hagati y’ibyo byombi mu bijyanye n’imiterere yabyo, imikorere yabyo, n’ibintu bifatika.

1. Itandukaniro ry'ingenzi: Gusobanukirwa imiterere yabyo ya shimi
Kugira ngo dutandukanye neza ibi bikoresho byombi, tugomba kubanza gusuzuma imiterere yabyo ya shimi.

Irangi ryo hasi rya Epoxy:
Irangi ryo hasi rya epoxy rigizwe ahanini na epoxy resin hamwe n'ikintu gitanga uburibwe. Iyo ibi bikoresho byombi bivanze, habaho uburyo bwa shimi bwitwa cross-linking. Ubu buryo ni nko kuboha iminyururu mito myinshi ya molekile mu buryo bukomeye mu rusobe rukomeye rw'ibice bitatu. Irangi rivamo rirangwa no gukomera kwaryo cyane, gufatana gukomeye, no kudakora cyane kwa shimi.

Tekereza ku gisasu cyo hasi cya epoxy nk'intwaro iremereye yambarwaga n'abarwanyi ba kera. Iyi ntwaro irakomeye cyane, irwanya neza kwangirika no kwangirika kw'imiti, irinda ubutaka cyane. Ariko, ikibazo cyayo ni nk'icy'intwaro iremereye: irakomeye cyane kandi ntishobora kwangirika. Iyo ubutaka bwo munsi bucitse bitewe n'ihindagurika ry'ubushyuhe cyangwa gutuza gato, iyi "ntwaro iremereye" ntishobora kwaguka cyangwa gucikamo kabiri, kandi ishobora no kwangirika hamwe na yo.

Irangi ryo hasi rya polyurethane:
Imiterere y'irangi rya polyurethane hasi iratandukanye, ahanini rigizwe na isocyanate na resin. Uburyo rikoreshwa mu gukora irangi rituma rigira imiterere yihariye: rigumana ubukana buhagije ariko rikagira ubunararibonye n'ubukomere bwiza. Abakora irangi bashobora guhindura imiterere yaryo, kimwe no gukaranga ifu, kugira ngo bagenzure "ubunararibonye" bwaryo n' "ubukomere bwaryo."

Bityo, irangi ryo hasi rya polyurethane rimeze nk'ikoti rigezweho kandi ridashobora gusigwa. Bitandukanye n' “ingabo zikomeye” za epoxy, ntabwo rikomera gusa; ahubwo rihuza gukomera no koroha. Iyo rikozweho n'ikintu kiremereye, rifata ingufu binyuze mu guhindagurika kwa micro-deformation, rikarinda gucika. Rinashobora kandi kwitwara neza mu guhindagurika guto mu butaka bwo munsi.

Mu magambo make, itandukaniro ry'ibanze ni iri:hasi hakozwe epoxyni uburyo "bukomeye", bukomeye kandi butoroshye nk'ikirahure;hasi hakozwe na polyurethaneni sisitemu "ikomeye", ikomeye kandi ihamye nk'umugozi.

2. Kugereranya imikorere y'ingenzi: Buri kimwe gifite ibyiza byacyo

Hashingiwe ku miterere itandukanye ya shimi yavuzwe haruguru, byombi bigaragaza ibyiza byabyo mu mikorere nyayo.

1. Imiterere ya mekanike
Ubukomere n'Ubudahangarwa: Mu bizamini bisanzwe by'ubukomere, hasi hakozwe neza neza hakozwe epoxy muri rusange bikora neza kurusha ahandi. Ubukomere bwaho bwiza bwo kudahangarwa butuma iguma neza mu bubiko burimo amakamyo n'amakamyo akunze gukoreshwa. Ariko, kudahangarwa kwa polyurethane ntabwo bikwiye gusuzugurwa, cyane cyane iyo bigeze ku bintu bifite impande zityaye (nk'inkweto ndende n'amapine y'icyuma). Ubuso bwayo bukora nk'uburinzi, bigatuma idahangarwa neza.
Ubudahangarwa bw'Ingaruka: Iki ni cyo kintu kiranga cyane. Igikoresho kiremereye cyamanuwe kivuye hejuru kikajya hasi mu cyuma gishyushya irangi gishobora gutuma irangi ricika cyangwa rikameneka. Ku butaka bwa polyurethane, ingaruka zirakwirakwira neza kandi zigashira, kandi hasi hashobora kongera kugaruka, hagakomeza kuba hameze neza. Kubwibyo, polyurethane ni amahitamo meza cyane ahantu nka za bibuga by'indege n'ibigo by'ibikoresho.

2. Kurwanya ikirere
Ubudahangarwa bw'imirasire y'izuba: Iyi ni yo nzitizi izwi cyane ku butaka bwa epoxy. Iyo bukoreshejwe hanze cyangwa mu cyumba cyo kuzuba, ntibuzamara igihe kinini mbere yuko ubuso butangira gushwanyagurika, gushwanyagurika no gutakaza ubwiza bwabwo. Imiterere yabwo ya shimi ituma budahangarwa n'imirasire y'izuba. Ubutaka bwa polyurethane (cyane cyane polyurethane ya aliphatic) busanzwe burwanya izuba kandi butanga ibara rirambye, bigatuma buba ibikoresho byiza byo gukiniraho hanze, ku gisenge cyo hejuru, no ku materase y'inyubako.
Ubudahangarwa bw'ubushyuhe: Ubusanzwe, ubushyuhe bwa epoxy buragabanuka cyane cyane kuri dogere selisiyusi 80; hejuru y'ubu bushyuhe, bukunda koroha. Ubushyuhe bwa polyurethane bufite ubushobozi bwo kwihanganira ubushyuhe bwinshi, cyane cyane mu bidukikije bifite ubushyuhe buke, bukomeza kugorama no kudakomera, bigatuma buba bwiza cyane mu kubika hasi mu buryo bukonje.

3. Ubudahangarwa bw'ibinyabutabire
Amarangi yo hasi ya epoxy afite ubucucike bwinshi atanga inyungu zikomeye mu kurwanya ingese zituruka ku bintu nka aside, alkali, umunyu, n'ibindi bintu bishongesha, bigatuma ahabwa izina rya "inzobere mu kurwanya ingese." Akoreshwa cyane mu bidukikije bikomeye nko muri laboratwari z'ibinyabutabire, inganda zikora ibikoresho by'amashanyarazi, n'inganda zikora imiti. Amarangi ya polyurethane kandi atanga ubudahangarwa bwiza bw'ibinyabutabire, yoroshye kwihanganira amavuta ya buri munsi, isabune, n'ibindi bintu byoroheje. Ariko, ubudahangarwa bwayo ku bintu byinshi byangiza cyane muri rusange ni buke ugereranyije n'ubw'amabara yo hejuru ya epoxy.

4. Ubunararibonye bw'Umukoresha
Ubudahangarwa bw'Ibyumviro n'Inyerera: Uburemere bw'ubutaka bwa polyurethane butuma burushaho kumererwa neza, bigabanura neza umunaniro uterwa no kumara igihe kirekire uhagaze. Binyuze mu gutunganya, bushobora kuremwa ahantu hatanyerera burundu, bigatuma habaho umutekano ndetse no mu bidukikije bikonje (nk'aho uruganda rw'ibiribwa rukarabira n'aho ruhagarara). Ahantu ho gukaraba ibiribwa harushaho kugorana, ariko ubuso bwaho bworoshye bworoshye gusukura neza.
Urwego rw'Isuku: Parike zombi za epoxy zitanga uburyo bwo kwirinda ivumbi mu buryo buboneye, zigahura n'ibisabwa mu isuku. Ariko, parike ya polyurethane ifite ubuso bunini kandi bworoshye, bukora nk'igitambaro gikingira, bigatuma bigorana ko ibyatsi (nk'irangi n'umutobe) byinjira, bigatuma isuku ya buri munsi yoroha cyane. Iyi miterere ituma ikundwa cyane mu nganda zifite ibisabwa bikomeye mu isuku, nko mu nganda zikora ibiribwa n'ibinyobwa, ndetse no mu nganda zikora ibikoresho by'ikoranabuhanga.

3. Imiterere n'uko ibintu bigaragara: Ibisobanuro birambuye ni ingenzi
Intambwe zo kubaka:
Byombi bisaba imbaraga, ubugari, no kuma kw'ubutaka bw'ibanze. Ubutaka bwa epoxy bukunda cyane cyane ubushyuhe n'ubushuhe mu gihe cyo kubaka. Ubushyuhe buke cyane cyangwa ubushuhe bwinshi bishobora kugira ingaruka ku gikorwa cyo gushya, bigatera ibibazo nko gupfunyika kw'umweru, gukomera, no kurangirira ku rubura. Ubutaka bwa polyurethane butanga ubushobozi bwo kwihanganira ubushyuhe n'ubushuhe.
Ingaruka zigaragara:
Ubutaka bwa epoxy bushobora gutuma habaho imiterere myiza kandi ikungahaye, imeze nk'indorerwamo kandi ikagira ishusho ikomeye y'inganda. Ubusanzwe, hasi ya polyurethane isaba irangi rito, bigatuma habaho imiterere yoroshye, ingana neza, kandi ikagira ibara ryoroshye kandi rirambye. Ubutaka bwa polyurethane terrazzo buherutse gukundwa bushobora gukora imitako myiza igereranywa n'amabuye karemano, kandi bukoreshwa mu maduka, mu byumba by'imurikagurisha, n'ahandi hantu, buvanga ubwiza n'imikorere.

4. Nigute wahitamo?
Uburyo busanzwe bwo gukoresha irangi rya epoxy hasi burimoahantu hatandukanye ho mu nganda, nko mu nganda zikora imashini ziremereye, mu maduka asanwa imodoka, mu bubiko, mu bibanza byo guparika imodoka munsi y’ubutaka, no mu nganda zikora ibikoresho by’ikoranabuhanga. Aha hantu harinzwe n’imirasire ya UV kandi hakenera umuvuduko mwinshi, kwangirika no kudakoresha imiti.

Ikoreshwa risanzwe mu gusiga irangi rya polyurethane hasi ririmoahantu ho hanze (ibibuga by'imikino, aho abantu bahagarara), ahantu ho mu nzu hashobora guhinduka ubushyuhe (ububiko bukonje), ahantu hafite isuku nyinshi kandi hadakenewe kunyerera (inganda z'ibiribwa, inganda zikora imiti, ibikoni by'ibitaro, inzira z'amashuri), n'ahantu hasaba kugabanya urusaku n'ingufu (ingoro ndangamurage, amasomero).

Ku bijyanye n'Ikiguzi
Hashingiwe ku giciro cy’ibikoresho, ubusanzwe hasi ya polyurethane iri hejuru ugereranyije n’iya epoxy. Ariko, mu gufata icyemezo, ni ngombwa kuzirikana "ikiguzi cy’ubuzima bwose". Ku bijyanye no gukoresha hanze, guhitamo hasi ya epoxy kugira ngo uzigame amafaranga bishobora gutuma ingwa icika mu mwaka umwe cyangwa ibiri gusa, bigasaba kuvugururwa, bigatuma ikiguzi cyose cyiyongera. Ku rundi ruhande, ku nganda zihamye zo mu nzu, hasi ya epoxy nta gushidikanya ko ari yo nzira ihendutse cyane.

5. Guhuza mu buryo bw'ubwenge: Sisitemu ihuriweho ikoresha imbaraga n'impinduka ku ntege nke
Uburyo bugenda bukundwa cyane mu mikoreshereze y'ibikorwa ni“Epoxy base + polyurethane topcoat”Sisitemu ivanze. Ubutaka bwa epoxy bukoreshwa nk'urwego rw'ibanze, bukoresha imbaraga zabwo, gufatana kwabwo, n'igiciro gito mu gushyiraho urufatiro; polyurethane ikoreshwa nk'igitambaro cyo hejuru, ikoresha imbaraga zayo zo kurwanya ikirere, kudasaza, n'ubwiza bwayo nk'urwego rwo hanze rwo kurinda. Ubu buryo buhuriweho akenshi butanga umusaruro mwiza udashobora kugerwaho n'igikoresho kimwe.

Incamake
Niba ukeneye kurinda hasi ihamye kandi idafite UV mu nzu, ifite umuvuduko ukabije n'ubudahangarwa bw'imiti, hasi hakozwe na epoxy ni amahitamo yizewe kandi ahendutse.
Niba hasi yawe hazaba hari ikirere gishyushye, ubushyuhe buhindagurika, cyangwa niba ukeneye urwego rwo hejuru rwo kwiyoroshya, kudacika intege, no kugira isuku ihagije, hasi ha polyurethane ni igisubizo cyiza cy’igihe kirekire.
