PU resin & ukutyabeka

inkcazelo emfutshane:

I-polyurethane casting resins zikhona kuzo zonke iimpawu kunye nobukhulu.Izibonelelo zee-PU resins zininzi njengeentlobo ezikhoyo.I-polyurethane resins ingasetyenziselwa zonke iintlobo zokubumba kunye neemodeli.Ngaphaya koko zisenokusetyenziswa phantsi kweendlela zokufunxa kunye nakwishishini elihlanganisiweyo.Iinreyi zePolyurethane zaziwa ngokuqina kwazo okuphezulu kunye nokunganyangeki kakuhle kokunxiba kunye nokuxhathisa imichiza.

Yintoni i-polyurethane?

I-Polyurethane yiplastiki efinyeziweyo njenge-PUR.Le plastiki yeyepolymers kwaye inamacandelo amabini ahlukeneyo: icandelo eliqinileyo kunye necandelo elithambileyo.Ngenxa yokuba i-PU iqulathe omabini amacandelo anzima kwaye athambileyo, izinto ziyirubha.Ngaphandle kwamacandelo amabini, i-PUR inokwahlulwa ibe yi-resin (i-coating) kunye ne-foam.

Iplastiki ikhona kuzo zombini iinguqulelo ze-1 kunye ne-2-component.Amacandelo amabini aquka icandelo A, isiseko se-resin, kunye necandelo B, i-hardener.Ngee-polyurethane resins usebenzisa i-hardener ethile kwindawo ethile yesicelo.Emva kokongeza le nto yokuqinisa ulwelo kwi-A component, inkqubo yekhemikhali iyenzeka.Le nkqubo iqinisekisa ukuqina kwe-resin.Ngokuxhomekeke kuhlobo lwe-hardener, oku kuya kuba nefuthe kwisantya kunye neempawu eziphathekayo.Nge-PU kubalulekile ukugcina umlinganiselo ochanekileyo.Ngokuxhomekeke kuhlobo lwecandelo, izinto zakho ziya kuhlala ziqinile okanye irabha elastiki emva kokunyanga.Ngenguqulo ye-foam, izinto eziphathekayo zandisa umthamo ngokobuninzi bawo.

Ukusetyenziswa kwe-polyurethane

I-polyurethane resins ingasetyenziswa njengeengubo, ii-primers, i-adhesives, i-lacquers, iipeyinti okanye i-resin yokuphosa.Njengepeyinti ecacileyo kunye ne-UV-resistant polyurethane yepeyinti yesinyithi okanye iplanga.Efanelekileyo ukugqiba i-parquet okanye imigangatho ephosiweyo.Ukongeza, izinto ezisetyenziswayo zikwasetyenziswa njengesikhumba sokwenziwa kwaye zisetyenziswa kwiisoli zezihlangu.

Amathuba okusetyenziswa kwe-polyurethane resins ayinamda kwaye asasazeka kumacandelo ahlukeneyo.

PU Cast umgangatho

Imigangatho ephothiweyo yePolyurethane sele ifumana ukuthandwa kwimarike yasekhaya kule minyaka idlulileyo njengokugqiba kweendawo zokuhlala, iikhitshi kunye namagumbi okulala.Ngombulelo kwiipropathi zayo zokuzilinganisa, le resin yenza umgangatho obhitye kakhulu kwaye wangoku.Ifumaneka ngemibala eyahlukeneyo ukuhambelana nethoni yangaphakathi yakho.Enkosi kwiipropathi zayo ezinwebekayo, unokuyisebenzisa ngokufudumeza okuphantsi kwaye ufumane indawo ehlala ixesha elide kwaye inganxibi.

Ipeyinti yePUR Sealine

Esinye sezona zicelo eziqhelekileyo ze-PU zifana ne-varnish okanye i-coating.Enkosi ngokuxhathisa okuhle kakhulu kwe-UV, ipeyinti ye-2K ye-polyurethane isetyenziswe kwimizi-mveliso iminyaka.Ingakumbi kwicandelo lezothutho, elaselwandle kunye nelokwakha.Ukuqina kunye neglosi ephezulu yenza i-Sealine PUR ibe yinto efanelekileyo yokupeyinta isikhephe sakho.
