Ikimenyetso cyo Kumenyekanisha Umuhanda Cyakozwe Niki? Ibigize n'imikorere byasobanuwe

Irangi ryerekana umuhanda rifite uruhare runini mumutekano wumuhanda uyobora abashoferi, abanyamagare, nabanyamaguru. Nubwo bisa nkaho byoroshye, imiterere yabyo yateguwe neza kugirango iringanize ibiboneka, biramba, nibikorwa bidukikije.
Muri rusange, ibara ryerekana umuhanda rigizwe nibice bine byingenzi: binders, pigment, kuzuza, ninyongera.
Binders ikora nka "kole" ifata irangi hamwe ikayifasha gukomera hejuru yumuhanda. Ibisanzwe bisanzwe birimo acrylic resin, alkyd resin, na epoxy cyangwa polyurethane sisitemu yo gukora cyane. Guhitamo binder ahanini bigena irangi riramba, guhinduka, no kurwanya kwambara.
Ibara ritanga ibara no kugaragara. Dioxyde ya Titanium ikoreshwa cyane mubimenyetso byera kubera ubwiza buhebuje no kwerekana, mugihe ibimenyetso byumuhondo akenshi bishingira ibara ryumuhondo kama cyangwa kama. Kugirango ijoro rigaragare, amasaro y'ibirahuri yongewemo haba mwirangi cyangwa kuminjagira hejuru kugirango habeho retroreflectivite mugihe amatara amurikira kuri bo.
Uzuza, nka calcium karubone cyangwa silika, bifasha kugenzura ubunini, ubwiza, nigiciro. Bitezimbere kandi birwanya skid, nibyingenzi mumutekano wibinyabiziga nabanyamaguru, cyane cyane mubihe bitose.
Inyongeramusaruro neza. Ibi birashobora kuba birimo anti-gutuza, UV stabilisateur, kwihuta byumye, nibikoresho birwanya skid. Mu marangi ashingiye kumazi, inyongera nazo zifasha kunoza igihe no gukama.
Imikorere biterwa nuburyo ibyo bice bikorana. Ibarabara ryiza cyane ryerekana irangi rigomba gukama vuba, kurwanya kwangirika nikirere, kugumana ibara mugihe, kandi bikaguma bigaragara kumanywa nijoro. Ibikorwa bigezweho bigenda byibanda kuri sisitemu nkeya-VOC hamwe n’amazi ashingiye kumazi kugirango yubahirize amabwiriza y’ibidukikije mugihe agitanga imikorere yizewe.
Muri make, irangi ryerekana umuhanda nibikoresho byateguwe neza kugirango umuhanda urinde umutekano, usobanutse, kandi uramba mugihe uhangayitse.
