Irangi ryo hanze rifite uruhare runini mukurinda inyubako ibintu bidukikije nkimvura, imirasire ya UV, nihindagurika ryubushyuhe. Kwemeza kuramba no gukora neza kwaya marangi ningirakamaro mugukomeza ubusugire bwuburanga nuburyo bwububiko. Kimwe mu bikoresho byateye imbere bikoreshwa mu kuzamura imikorere y’amabara yo hanze ni Redispersible Polymer Powder (RDP). RDPs ikoreshwa mugutezimbere kuramba, guhinduka, hamwe n’amazi arwanya amarangi, bigatuma arushaho kuba mwiza kubibazo byo hanze.
Gusobanukirwa Ifu ya Polymer isubirwamo (RDP)
RDPs ni polymer zishonga mumazi zishobora gusubizwa mumazi nyuma yo gukama. Iyi poro isanzwe ishingiye kuri vinyl acetate-Ethylene (VAE), vinyl acetate-vinyl ester ya acide itandukanye (VeoVa), cyangwa kopi ya acrylic. RDPs ikorwa binyuze mubikorwa byitwa spray yumye, aho polymer ya emulsion yumishijwe mubifu nziza. Iyo ivanze namazi, izo poro zongera kwigana mumashanyarazi ya latex, zishobora gukoreshwa nka binder mubikorwa bitandukanye byubwubatsi, harimo amarangi.
Uburyo bwa RDP mukuzamura irangi rirambye
Kunoza neza:
RDP izamura imiterere ya adhesion yamabara yo hanze. Gufata neza byemeza ko irangi ryiziritse kuri substrate, bikagabanya amahirwe yo gukuramo cyangwa guhindagurika mugihe cyikirere kibi. Polimeri muri RDP ikora firime yoroheje kandi ikomeye hejuru yisize irangi, iteza imbere ubumwe bwiza.
Kongera imbaraga zo guhinduka no guhangana na Crack:
Ihinduka rya firime ya polymer yakozwe na RDP ningirakamaro kumarangi yo hanze. Inyubako zishobora kwaguka no gushyuha, bishobora gutera firime irangi. RDP itanga ubuhanga bukenewe ku irangi, ikayemerera kwaguka no gusezerana na substrate idacitse, bityo ikongerera ubuzima irangi.
Kurwanya Alkali na Efflorescence:
Ubuso bwa alkaline, nka beto na plaster, burashobora gutuma amarangi gakondo yangirika. RDP itezimbere alkali irwanya amarangi, irinda saponification no kwangirika kwa firime. Byongeye kandi, bafasha mukugabanya efflorescence, aho umunyu uva muri substrate wimukira hejuru, bigatera ububiko bwera butagaragara.
Kongera Amazi Kurwanya Amazi binyuze muri RDP
Indangabintu ya Hydrophobi:
RDP irashobora gutanga hydrophobique kumiterere yinyuma. Ibi bivuze ko irangi ryanga amazi, bikagabanya kwinjiza amazi na substrate. Irangi rya hydrophobique ririnda amazi kwinjira, rikaba ari ingenzi cyane mu kurinda ibintu byangiritse kwangirika kw’ubushuhe nko gukura kw'ibumba, gucika intege, no kuzunguruka.
Imiterere ya firime no guhuriza hamwe:
Ubushobozi bwo gukora firime ya RDP bugira uruhare runini mukurwanya amazi. Filime ikomeza, ihujwe na polymer ikora inzitizi amazi abona bigoye kwinjira. Iyi firime ifunga uduce duto duto kandi dusatuye mu irangi, byongera imbaraga zo kurinda imvura nubushuhe.
Kunoza Kurwanya Imyuka Yumuyaga:
Mugihe RDP yongerera imbaraga amazi, nayo ikomeza kuringaniza yemerera imyuka y'amazi guhunga. Uyu mutungo urinda kwiyongera k'ubushuhe inyuma ya firime yo gusiga irangi, bishobora ubundi gutuma habaho kubyimba cyangwa gukuramo. Rero, RDP ifasha mukurema umwuka uhumeka nyamara utarwanya amazi.
Porogaramu Ifatika ninyungu
Inzira ndende yo gufata neza:
Irangi ryahinduwe hamwe na RDP ryerekana igihe kirekire cyo kubaho ugereranije namabara gakondo. Ibi bisobanura bike byo gusiga irangi hamwe nigiciro cyo kubungabunga igihe. Kubafite inyubako n'abayobozi, iyi ni inyungu ikomeye mubukungu.
Kubungabunga Ubwiza:
Gukoresha RDP bifasha mukubungabunga ubwiza bwinyubako. Kongera imbaraga no kurwanya ibintu bidukikije bivuze ko irangi rigumana ibara ryaryo kandi rikarangira igihe kirekire. Ibi ni ingenzi cyane ku nyubako z'ubucuruzi n'inzu z'umurage aho kugaragara ari ngombwa.
Kuramba hamwe n'ingaruka ku bidukikije:
RDPs igira uruhare mu kuramba kw'amabara yo hanze. Mu kongera igihe cyo gusiga irangi, bigabanya inshuro zo gusiga irangi, ari nako bigabanya ingaruka z’ibidukikije zijyanye no gukora amarangi, kuyashyira mu bikorwa, no kujugunya. Byongeye kandi, ibyinshi muri RDP byashizweho kugirango bitangiza ibidukikije, hamwe n’ibice bike by’ibinyabuzima bihindagurika (VOC).
Ibibazo n'ibitekerezo
Ikiguzi:
Mugihe RDP itanga inyungu nyinshi, zirashobora kandi kongera ikiguzi cyo gusiga amarangi. Ibyiza byubukungu byo kugabanya kubungabunga no kuramba kuramba akenshi byuzuza ibiciro byambere byambere, ariko ni ukureba kubakora n'abaguzi.
Guhuza nibindi Byongeweho:
Imikorere ya RDP irashobora guterwa no kuba hari izindi nyongeramusaruro mugutegura irangi. Kwemeza guhuza no gukora neza bisaba gukora neza no kugerageza.
Uburyo bwo gusaba:
Kwinjiza RDP birashobora gusaba guhinduka muburyo bwo gusaba. Kuvanga neza no kubishyira mu bikorwa ni ngombwa kugirango ugere kubikorwa byifuzwa.
Ifu ya Redispersible Polymer Ifite uruhare runini mukuzamura igihe kirekire hamwe n’amazi arwanya amarangi yo hanze. Mugutezimbere, guhuza, no kurwanya ibintu bidukikije, RDP ifasha mukurema imyenda ndende kandi ikingira inyubako. Inyungu zo gukoresha amarangi yahinduwe na RDP, nkigihe kirekire cyo kubungabunga, kubungabunga ubwiza, no kubungabunga ibidukikije, bituma bahitamo neza kubwubatsi bugezweho. Nubwo imbogamizi zijyanye nigiciro no kugena, inyungu rusange zitangwa na RDP zituma zigira uruhare runini mugutezimbere amarangi yo hanze akora neza. Uko ikoranabuhanga rigenda ritera imbere, imikorere nogukoresha kwa RDP birashoboka ko byaguka, bikarushaho gushimangira akamaro kabo mubikorwa byubwubatsi.
