I-PU resin & coating Isithombe esifakiwe

I-PU resin & enamathela

incazelo emfushane:

Ama-resin e-polyurethane cast akhona kuzo zonke izimfanelo nobukhulu.Izinzuzo zama-PU resins ziningi njengezinhlobo ezikhona.Ama-polyurethane resins angasetshenziswa kuzo zonke izinhlobo zokubunjwa namamodeli.Ngaphezu kwalokho zingasetshenziswa ngaphansi kwamasu e-vacuum nasembonini eyinhlanganisela.Ama-polyurethane resins aziwa ngokunwebeka kwawo okuphezulu nokumelana nokugqokwa okuhle kanye nokumelana namakhemikhali.

Iyini i-polyurethane?

I-polyurethane ipulasitiki efushanisiwe njenge-PUR.Le pulasitiki ingeyama-polymers futhi iqukethe izingxenye ezimbili ezihlukene: ingxenye eqinile kanye nengxenye ethambile.Ngoba i-PU iqukethe womabili amasegimenti aqinile futhi athambile impahla iyirubha.Ngaphandle kwezingxenye ezimbili, i-PUR ingabuye ihlukaniswe ibe yi-resin (enamathela) kanye negwebu.

Ipulasitiki ikhona kuzo zombili izinguqulo zengxenye engu-1 no-2.Izingxenye ezimbili zihlanganisa ingxenye A, i-base resin, kanye nengxenye B, i-hardener.Nge-polyurethane resins usebenzisa i-hardener ethile endaweni ethile yohlelo lokusebenza.Ngemva kokwengeza lesi siqinisi esiwuketshezi engxenyeni engu-A, kwenzeka inqubo yamakhemikhali.Le nqubo iqinisekisa ukuqina kwe-resin.Kuye ngohlobo lwe-hardener, lokhu kuzothonya isivinini kanye nezakhiwo ezibonakalayo.Ngama-PU kubalulekile ukugcina izilinganiso ezifanele.Ngokuya ngohlobo lwengxenye, impahla yakho izohlala iqinile noma i-raber elastic ngemuva kokuphulukiswa.Ngenguqulo ye-foam, impahla ikhula ngevolumu ngokuya ngokuminyana kwayo.

Izicelo ze-polyurethane

Ama-polyurethane resins angasetshenziswa njengezingubo zokugqoka, iziqalo, izinamathiselo, ama-lacquers, amapende noma ama-casting resins.Njengopende we-polyurethane obala futhi ongamelana ne-UV wensimbi noma ukhuni.Ilungele ukuqedela i-parquet noma i-cast floor.Ngaphezu kwalokho, impahla ibuye isetshenziswe njengesikhumba sokwenziwa futhi isetshenziswa ematheni ezicathulo.

Amathuba okufaka ama-polyurethane resins awanamkhawulo futhi asakazwa emikhakheni ehlukene.

Iphansi le-PU Cast

I-Polyurethane cast floors iye yathola ukuthandwa emakethe yasekhaya eminyakeni yamuva njengendawo yokuqeda izindawo zokuhlala, amakhishi kanye namakamelo okulala.Ngenxa yezakhiwo zayo zokuzilinganisa, le resin yenza isiphetho saphansi esicwebezelayo nesimanjemanje.Itholakala ngemibala ehlukene ukuze ifane nethoni yengaphakathi lakho.Ngenxa yezakhiwo zayo ezinwebekayo, ungayisebenzisa futhi ngokufudumeza kwangaphansi futhi uthole isiphetho esihlala isikhathi eside futhi esingagugi.

I-PUR ngopende Sealine

Enye yezinhlelo ezivame kakhulu ze-PU ifana ne-varnish noma i-coating.Ngenxa yokumelana okuhle kakhulu kwe-UV, upende we-2K polyurethane usetshenziselwe izinhlelo zezimboni iminyaka.Ikakhulukazi emikhakheni yezokuthutha, eyasolwandle neyokwakha.Ukuqina nokucwebezela okuphezulu kwenza i-Sealine PUR ibe isiphetho esihle sokupenda isikebhe sakho.
