Mumakore achangopfuura, nekutungamirirwa kwemitemo yekuchengetedza kwezvakatipoteredza uye kukurudzirwa kwevakawandacoatingvagadziri, mvurabornpendi yave ichiwedzera kuzivikanwa nemusika, uye kuita kwependi ine zvikamu zviviri zvemvura yakafananidzwa neyependi yakavakirwa pamafuta mune zvakawanda, izvo zvisingaparadzaniswe kubva mukusimudzirwa nekushandiswa kwependi.mvura PUkurapa mumiririri.
Bogao's waterbornePUkurapa mumiriririBG-2655-80,fkana machira anotakurwa nemvura, zvinonamirwa nemvura, ingi dzine mvura, nezvimwe.
Zviriinoshandiswa seanorapa ejenti zvikamu zvemvura inotakura maviri-chikamuPUsystem.
Iyo ine hunhu hwePaint firimu nekukurumidza kuomesa, yakanakisa yemuviri uye makemikari zvimiro.
Yemvura PU yekurapa mumiriri ine huwandu hukuru hwemapoka eisocyanate (- NCO), ayo anogona kudzoreredzwa nemapoka akawanda anoshanda senge hydroxyl, amino uye carboxyl mapoka.Maitiro ekunyatso kudzora maitiro epadivi uye kugadzirira iyo miviri-yechikamu pendi yemvura ine basa rakanakisa inoda kusarudza yakakodzera yemvura inorapa mumiriri, uye kugona mapoinzi akakosha ekugadzira dhizaini uye gadziriro yefirimu zvakadzama.
Iko kutsvagisa kwekushandisa kwemvura PU yekurapa mumiririri yakatanga mukupera kwema1980s.Bayer yanga iri pamberi pekutsvagisa nekusimudzira, uye yakabatsirawo mukusimudzirwa kwemvura inorapa mushonga uye pendi yemvura.Yakatanga kunonoka kuChina, asi yakakurumidza kukura, uye inoshandiswa zvakanyanya mukugadzira maindasitiri, machira epasi, machira emapuranga, indasitiri yemotokari, indasitiri yemachira nemimwe minda.
- Kushandiswa muzvigadzirwa zvemabhizimisi
Mvura inotakura PU yekurapa inofananidzwa nemvura inotakura hydroxyl dispersion resin.Nekuti iyo hydroxyl dispersion ine diki molecular huremu, yakakwira hydroxyl kukosha uye isina surfactant, ine yakakwira density, kuomarara kwakanyanya, kupenya kwakanaka uye kuramba kwakanaka mushure mekuyambuka nekurapa.Inogona kufananidzwa zvachose nemafuta-based coatings mukuita, uye inogona kushandiswa zvakanyanya muindasitiri inorwisa-corrosion uye yekushongedza machira.
- Kushandiswa mukuputira pasi
Zvikamu zviviri zvemvura PUkupfekedza kunoshandiswa kune mvura-based floor, iyo ine maitiro ekuchengetedza kwezvakatipoteredza uye hutano.MvuraPUcoating ine hunhu hwekuchinjika kwepamusoro, kusamira kwekusapfeka, kuramba kwemamiriro ekunze, kusamira kwemvura uye kuramba kwakanaka kwekukwenya.
- Kushandiswa mu Wood Coatings
Pendi yehuni yemhando yepamusoro-soro inzira yeindasitiri yefenicha.Iyo firimu yepende inopa kunaka kwemavara kunzwa mushure mekutsakatika, uye inofarirwa kwazvo nevanhu.Iyo varnish yekuputira yakawedzerwa ne matting agent ine yakaderera kujeka uye kushomeka kuramba kune yepakati.Iyo matting mhedzisiro inogona kuwanikwa kuburikidza neanorapa agent kubva kune molecular chimiro.Rudzi rwakafanana rwependi yemvura, ine chimiro chakasiyana che matte kurapa agent, inogona kuwana gloss yatinoda.
