Ibisobanuro by'igicuruzwa
Polyurea ni ikintu gikoreshwa cyane cyakoreshejwe neza mu kurwanya ingese ku butaka bw'ibigega byo kubikamo ibintu, mu kurinda inyubako za sima amazi nko mu bigega byo guparika imodoka, mu bigega by'amazi, no mu miyoboro y'amazi, ndetse no mu byuzuza cyangwa mu gufunga ingingo.
- Urutonde rurerure rw'ibikoresho rushobora kugaragara nk'ibyakoreshejwe nk'imyenda idapfa amazi. Mu binyejana byinshi, uburyo bwonyine bwari buhari bwari ibikoresho bishingiye kuri asphalt. Mu kinyejana cya 20, hari ibindi bikoresho byinshi byakozwe, harimo epoxy na vinyl ester.
- Polyurea ni ikoranabuhanga rigezweho ryo gusiga. Iki gikoresho cyakorewe inganda z'imodoka mu mpera za 1980, ubu gikoreshwa cyane mu nzego zitandukanye. Bitewe n'uko gikira vuba, kidatwarwa n'ingese, kandi kidapfa kwangirika, cyateye intambwe igaragara mu buhanga bwo kwirinda amazi mu myaka 10 ishize.
- Ubwo polyurea yavumburwaga, byari byifujwe ko ibikoresho bya polyurethane bitagoranye ku mazi. Mu gusimbuza amatsinda ya carboxyl muri polyurethane n'amatsinda ya amino, umusaruro ubu twita polyurea wabonetse. Uyu musaruro ntugoranye ku mazi cyane kurusha izindi palasitike zishingiye kuri polyurethane.
- Polyurea ifite ubwoko bubiri busanzwe. Polyurea ihumura neza ikoreshwa kenshi. Imikorere y'iki gicuruzwa ishobora gutandukana cyane, bityo ikaba ifite uburyo bwinshi butandukanye bwo kuyikoresha. Mu by'ukuri, ikibazo cyonyine cy'iki gipfuka ni ukudahagarara neza kw'imirasire ya UV. Ubundi bwoko ni polyurea ya aliphatic. Hakoreshejwe uburyo butandukanye bwa shimi kugira ngo igire kudahagarara neza kwa UV, hatangwa igihano. Igiciro cya polyurea akenshi kiba inshuro ebyiri icya polyurea ihumura neza.
Ibiranga ibicuruzwa
Irangi rya polyurea, nk'ubwoko bushya bw'irangi rikora neza, rifite imiterere myinshi itangaje.
- Ifite imiterere myiza cyane, nko kudashira neza, bituma irangi rigumana ubuziranenge bwaryo n'ingaruka zaryo zo kurinda igihe kirekire ndetse no mu bidukikije bishobora kwangirika no gusaza kenshi;
- Muri icyo gihe, ifite ubudahangarwa bukomeye ku ngaruka, irwanya neza imbaraga z'ingaruka zo hanze kandi ikarinda ubuso bw'ikintu gitwikiriwe kwangirika.
- Ku bijyanye n'imiterere y'ibinyabutabire, irangi rya polyurea rigaragaza ubudahangarwa budasanzwe bwo kwangirika kw'ibinyabutabire. Byaba bihuye n'ikwirakwizwa rya aside, alkali, cyangwa ahantu habi hakoreshwa ibinyabutabire nko mu bushyuhe bwinshi no mu gusiga umunyu mwinshi, bishobora kugumaho igihe kirekire kandi ntibikunze kugira ingaruka mbi ku binyabutabire bigatera kwangirika kw'irangi.
- Byongeye kandi, ifite ubushobozi bwo guhangana n’ikirere neza, ikomeza gukora neza mu bihe bitandukanye, nko mu bushyuhe bwinshi, ubushyuhe buke, n’imirasire ya ultraviolet, idahura n’ibibazo nko gushwanyagurika, guhinduka ibara, cyangwa gushishwa bitewe n’imihindagurikire y’ikirere. Umuvuduko wo gushwanyaguza kwa polyurea coatings ni mwinshi cyane, ibyo bikaba byongera imikorere myiza mu bwubatsi kandi bigatuma coatings zirangira kandi zigashyirwa mu bikorwa mu gihe gito.
- Byongeye kandi, ifite uburyo bwo gufata neza ibintu bitandukanye, ikaba ishobora gufata neza ku buso bw'ibyuma, sima, imbaho, nibindi, bigatuma ikora urwego rwo kurinda rukomeye kandi ruhamye.
IBYIZA BY'IBICURUZWA
- Imwe mu mpamvu zatumye irangi rya polyurea rikundwa cyane ni imiterere yaryo myiza cyane. Urubuga rwa Polyurea.com ruvuga ku mugaragaro ko ukurikije imiterere ifatika ihari, nta yindi irangi ku isi ishobora kuba ihwanye na polyurea. Mu guhindura formula, ibicuruzwa bya polyurea bishobora kugira imiterere myinshi cyane, kuva ku burebure bunini kugeza ku mbaraga nziza zo gukurura, ariko ibi bifitanye isano n'uburyo ibikoresho bikoresha n'ikoreshwa neza. Polyurea ifite uburyo bwiza bwo gufata ibintu bitandukanye birimo sima, icyuma, n'ibiti, nubwo nta primer, kandi ishobora gukoreshwa ahantu hari ubushyuhe bwinshi n'ubushuhe bwinshi. Ahari inyungu itangaje ya polyurea ni uko ikira vuba cyane. Iyo imaze gukoreshwa, polyurea ishobora kugera ku bunini busabwa mu gipfundikizo kimwe, cyihuta inshuro nyinshi kurusha iyo hakoreshejwe irangi risanzwe, bigatuma nyirayo ashobora kongera gukoresha icyo gikoresho kandi bikagabanya igihombo giterwa n'igihe cyo kudakora.
- Ubunini bw'imyambaro ya polyurea ikoreshejwe rimwe bushobora kuva kuri 0.5mm kugeza kuri 12.7mm, kandi igihe cyo kuyifata kiri hagati y'ako kanya n'iminota 2, ibi bikaba bituma ikoreshwa vuba.
- Nk'igitambaro kinini gikira vuba, iyo hakenewe uburyo bwo kwirinda amazi burambye kandi butagoramye, polyurea ni amahitamo meza. Izindi miterere, nko gusaba ko amazi adatemba no kumera neza, zishobora kugerwaho binyuze mu buryo bumwe na bumwe. Igitambaro gishobora gusigwa irangi ndetse gishobora no gukoreshwa ahantu hujuje ibisabwa mu mazi yo kunywa.
- Bitewe n'imiterere yayo myinshi y'imikorere, polyurea ifite uburyo bwinshi bwo kuyikoresha. Uduce tw'imbere tw'ibigega byo kubikamo ibintu, urwego rwo hejuru rw'uburinzi, hamwe n'uburinzi bw'ibiraro ni byo bikoreshwa cyane muri ubwo bwoko bw'ibikoresho. Mu by'ukuri, amahirwe yo gukoresha polyurea ntagereranywa.
- Ibigega by’inganda zitunganya amazi yanduye bikunze kugira ikibazo cy’imyuka, gukurura, n’ingufu nyinshi za hydrogen sulfide mu gihe cyo kuyungurura, kuvanga no gukura amazi mu mazi. Gukoresha polyurea bishobora gutanga uburyo bukenewe bwo kurwanya kwangirika, kurwanya imiti, no kurwanya ingaruka, kandi bishobora gusubiza uruganda mu buryo bwihuse, ibyo bikaba byihuta cyane kurusha ubundi buryo bwinshi.
- Iyo ikoreshejwe ku biraro n'ahandi hantu hashobora kunyeganyega no kwimuka, ubwiyongere bwa polyurea ni ikindi cyiza ugereranyije n'udupira tworoshye kandi tudakomeye nka epoxy.
Ibura ry'ibicuruzwa
- Birumvikana ko polyurea ifite n'ingaruka mbi zimwe na zimwe. Ibikoresho bikenewe mu gushyiramo irangi rya polyurea birahenze cyane, kuva ku madolari 15.000 kugeza ku madolari 50.000 cyangwa birenga. Urubuga rw'ubwubatsi rugendanwa rufite ibikoresho byose rushobora kugura kugeza ku madolari 100.000.
- Igiciro cy'ibikoresho bya polyurea nacyo kiri hejuru y'icy'ibindi bipfuka. Igiciro cya mbere kiri hejuru y'icya epoxy. Ariko, kubera ko igihe cyo gukora cy'ibipfuka bya polyurea kiri inshuro 3 kugeza kuri 5 z'ibindi bicuruzwa, igiciro cyo gukora mu gihe cyo gukora kiracyafite ibyiza.
- Kimwe n'ibindi bikoresho byose bikingira amazi, imyubakire idakwiye ishobora no gutuma ikoreshwa rinanirwa. Ariko, ibisabwa mu bwubatsi hakoreshejwe irangi rya polyurea ni byinshi cyane. Gutunganya ubuso nko gutwika umucanga cyangwa gushushanya ni ingenzi cyane kuri polyurea. Imishinga myinshi ya polyurea yananiwe ntabwo ifitanye isano na polyurea ubwayo, ariko iterwa no gutunganya ubuso nabi cyangwa nabi.
Ubwubatsi
- Polyurea nyinshi zikoreshwa mu gusukura amazi zubakwa hakoreshejwe ibikoresho byinshi byo gusukura. Ubusanzwe, hakoreshwa uburyo bw'ibice bibiri, aho uruvange rwa amino resin n'ibikoresho bya isocyanate biba biri ukwabyo mu bikoresho bya litiro 50. Mu gihe cyo kubaka aho akazi kakorerwa, ibirimo mu bikoresho bya litiro 50 byimurirwa mu kigega cy'ibikoresho byo gusukura hanyuma bigashyuha kugeza ku bushyuhe bukwiye (60-71°C). Hanyuma, isocyanate na polyol resin byoherezwa binyuze mu muyoboro ushyushye bijya mu mbunda yo gusukura.
- Igipimo cy'ibintu bibiri kigenzurwa neza, akenshi ku gipimo cya 1: 1.
- Igihe cyo gukira kwa polyurea gipimwa mu masegonda, bityo iyi miti ishobora kuvangwa gusa ako kanya ivuye mu mashini itera imiti; bitabaye ibyo, izakira kandi igakomera mu mashini itera imiti.
- Bamwe mu bakora bagurisha ibikoresho byose byo gutera imiti bigendanwa, harimo n'ibikoresho byose, bishyirwa ku magare cyangwa ku buriri bw'amakamyo.
