Ipeyinti yoMgangatho we-Epoxy vs. Ipeyinti yoMgangatho wePolyurethane: Uhlalutyo oluNzulu loMmahluko wabo kunye nokukhetha oLungileyo
Sihamba kwiiflethi zanamhlanje zefektri, kwiindawo zokuthenga ezinkulu, nakwiigaraji ezingaphantsi komhlaba, sihlala sinyathela kungekuphela kwisamente eqhelekileyo kodwa kwipeyinti ekhethekileyo egudileyo, ekhazimlayo, nenemibala. Le yimpembelelo yepeyinti yomgangatho. Phakathi kweendlela ezininzi,ipeyinti yomgangatho ye-epoxy kunye ne-polyurethaneEli nqaku liza kujonga ngononophelo umahluko phakathi kwezi zimbini ngokwendalo yazo, ukusebenza kwazo, kunye neemeko ezifanelekileyo.
1. Umahluko oPhambili: Ukuqonda iNdalo yazo yeeKhemikhali
Ukuze sahlule ngokwenene phakathi kwezi zinto zimbini, kufuneka siqale sihlolisise ukwakheka kwazo kweekhemikhali.
Ipeyinti yomgangatho we-Epoxy:
Ipeyinti yomgangatho we-epoxy yenziwe ngokuyintloko nge-epoxy resin kunye ne-ejenti yokuphilisa. Xa ezi zinto zimbini zixutyiwe, kwenzeka inkqubo yeekhemikhali ebizwa ngokuba yi-cross-linking. Le nkqubo ifana nokuluka imixokelelwane emininzi ye-molecular ngokuqinileyo kwinethiwekhi eqinileyo enemilinganiselo emithathu. Ifilimu yepeyinti ephumayo ibonakaliswa bubunzima bayo obuphezulu, ukunamathelana okunamandla, kunye nokumelana okukhulu kweekhemikhali.
Cinga ngefilimu yokupenda phantsi ye-epoxy njengesikrweqe esinzima esasinxitywa ngamajoni amandulo. Esi sikrweqe sinamandla kakhulu, simelana ngempumelelo nokukrala kunye neekhemikhali ezitshayo, sikhusela umhlaba ngokuqinileyo. Nangona kunjalo, ingxaki yaso ifana neyesikrweqe esinzima: siqinile kakhulu kwaye asinakuguquguquka. Xa umhlaba ongaphantsi uqhekeka ngenxa yokutshintshatshintsha kobushushu okanye ukuhlala kancinci, esi “sikrweqe esinzima” asikwazi ukwanda okanye ukunqunyulwa naso, kwaye sinokuqhekeka naso.
Ipeyinti yomgangatho wePolyurethane:
Ukwakheka kwepeyinti yomgangatho we-polyurethane kwahlukile, ikakhulu kuqulethwe yi-isocyanate kunye nezinto ze-resin. Inkqubo yayo yokusabela inika iipropati ezikhethekileyo kwifilimu yepeyinti: igcina ubulukhuni obaneleyo ngelixa ikwanokuqina okugqwesileyo. Abenzi be-formula banokuguqula ukwakheka, njengokuxova intlama, ukulawula "ubuthambile" kunye "nobunzima" bayo.
Ngoko ke, ipeyinti yomgangatho we-polyurethane ifana kakhulu nevesti yobuchwepheshe obuphezulu, engahlatywayo. Ngokungafaniyo ne-epoxy "heavy armor," ayiqini nje kuphela; endaweni yoko, idibanisa ukuqina kunye nokuguquguquka.
