Ipitingi ya polyurea imara igihe kingana iki?
Igihe cyo kubaho kwa polyurea kizaterwa nibintu bitandukanye, harimo ubunini bwikibiriti, ubwoko bwa polyurea bwakoreshejwe, nuburyo bugaragaramo.Muri rusange, impuzu za polyurea zizwiho kuramba kandi zirashobora kumara imyaka myinshi hamwe no kuyifata neza.Ibipapuro bimwe na bimwe bya polyurea byateguwe kubikorwa byigihe kirekire kandi birashobora kumara imyaka mirongo.
Ariko rero, ni ngombwa kumenya ko nta gipfundikizo kitangirika rwose kandi impuzu zose amaherezo zizasenyuka mugihe runaka.Uburebure bwigihe polyurea izamara bizaterwa nuburyo bwihariye bugaragaramo, nkubwinshi bwimodoka cyangwa kwambara no gutanyaguza uburambe, kuba hari imiti cyangwa ibidukikije bishobora gutesha agaciro igifuniko, na urwego rwo kubungabunga rwakira.Kugenzura no kubungabunga buri gihe birashobora gufasha kwagura ubuzima bwa polyurea kandi bikareba ko bikomeza gutanga imikorere myiza.
Ese polyurea itwikiriye amazi?
Nibyo, impuzu za polyurea zizwiho uburyo bwiza bwo kwirinda amazi.Iyo ushyizwe hejuru, polyurea ikora urwego rukomeza, rutagira ikizinga rwihanganira cyane kwinjira mumazi.Bikunze gukoreshwa nkigifuniko kitarinda amazi hejuru yinzu, urufatiro, nubundi buso bugaragaramo amazi.
Usibye ubushobozi bwayo bwo kwirinda amazi, impuzu za polyurea zizwiho kandi guhangana n’imiti n’ubushobozi bwo guhangana n’ibidukikije bikaze.Ibi biranga, hamwe nigihe cyacyo cyo gukira byihuse hamwe nubushobozi bwo guterwa ahantu hatandukanye, bituma ihitamo gukundwa cyane no kwirinda amazi nibindi bikoresho byo gukingira.
Ese polyurea itwikiriye?
Kurwanya kunyerera kwa polyurea bizaterwa nuburyo bwihariye hamwe nubuso bwakoreshejwe.Ibipapuro bimwe na bimwe bya polyurea bikozwe hamwe birangiye cyangwa byuzuye kugirango birusheho kunanirwa kunyerera, mugihe ibindi biroroshye kandi biranyerera.Muri rusange, impuzu za polyurea ntizishobora kunyerera nkubundi bwoko bwimyenda, nka epoxy cyangwa reberi ishingiye kuri rubber.
Niba kunyerera kunyerera biteye impungenge, birashobora kuba byiza guhitamo igipfundikizo cya polyureya cyateguwe byumwihariko kugirango irusheho kunanirwa kunyerera cyangwa kongeramo inyongeramusaruro itanyerera mbere yo gukoreshwa.Ni ngombwa kandi gutekereza ku buso igifuniko kizakoreshwa, kuko ubuso bumwe busanzwe butanyerera kurusha ubundi.Kurugero, hasi ya beto yoroshye irashobora kunyerera kuruta ubuso bubi cyangwa bubi.
