Uphononongo ngoHlengahlengiso lweresin yeeNgqungquthela zeAlkyd Resin eziseManzini eziFakelweyo ngumfanekiso

Uphononongo malunga nokuguqulwa kweresin yeeNgqungquthela zaseManzini zeAlkyd Resin

Inkcazelo emfutshane:

I-Alkyd resin coating iye yaba yenye yezona zinto zifundiswa kwaye zaveliswa iingubo kwi-coating industry ngenxa yokufumaneka lula kwezinto eziluhlaza, ixabiso eliphantsi kunye neglosi egqwesileyo, ukuguquguquka kunye nokubambelela.Nangona kunjalo, i-alkyd resin yokugqoka i-alkyd ineziphene ezifana nobunzima bokugquma okuphantsi, ukuxhathisa kwamanzi kunye nokumelana nobushushu, kwaye isicelo sayo asikwazi ukuhlangabezana neemfuno zophuhliso lwemizi-mveliso yokusebenza okuphezulu.Kuyimfuneko ukuguqula kunye nokwandisa intsimi yesicelo se-alkyd resin coating.

Okwangoku, kukho iinkalo ezimbini kuphando malunga nokuguqulwa kweengubo ze-alkyd resin: ukuguqulwa kwe-resin kunye nokuguqulwa kwe-pigment.Ukuguqulwa kwe-resin kukwazisa amanye amaqela kwi-resin chain chain segment, okanye nge-polyurethane resin, i-acrylic resin, i-epoxy resin kunye ne-silicone resin.Ukuguqulwa kwe-pigment kunye ne-filler ikakhulu ukongeza ii-pigments ezahlukeneyo ezisebenzayo kunye nezihlunu zokuphucula ukusebenza kweengubo ze-alkyd resin.Eli phepha lazisa uphononongo malunga nokuguqulwa kweengubo ezimbini ze-alkyd resin zasemanzini.

Uphononongo malunga nokuguqulwa kweresin yeeNgqungquthela zaseManzini zeAlkyd Resin

1. Ukulungiswa kwe-oli-water alkyd resin evela kwimbewu ye-Zanthoxylum bungeanum ngokuthotywa kwenkunkuma yebhotile ye-polyethylene terephthalate (PET)
ULei Rui weYunivesithi yaseShaanxi yesayensi kunye nobuchwepheshe, njl.njl. ulungiselele i-alkyd resin ye-oyile ye-alkyd eguquliweyo yembewu ye-Zanthoxylum bungeanum ngokusebenzisa inkunkuma yeebhotile ze-PET, i-trimethylolpropane (TMP) kunye ne-oyile yembewu ye-Zanthoxylum bungeanum engatyiwayo njengezinto eziphambili, i-phthalic anhydride ( PA) njenge-monomer acidic, i-2,2-Dimethylolpropionic acid (i-DMPA) njenge-monomer enamanzi, kunye ne-n, i-N-Dimethylethanolamine njenge-agent engathathi hlangothi.Iziphumo zokuvavanya ukusebenza kwengubo zibonisa ukuba xa isiselo sotywala si-11.5%, umxholo weoli ngu-50%, w (PET) = 9.3%, w (DMPA) = 10%, i-coating inokugcinwa kakuhle kokugcinwa, kunye namanzi. ukumelana, ubulukhuni kunye nokuzinza kwe-thermal kuphuculwe kakhulu xa kuthelekiswa ne-alkyd eqhelekileyo yamanzi.
2. I-silicone acrylate i-polyurethane eguqulwe emanzini i-alkyd anticorrosive coating
I-alkyd resin yalungiswa ngokusabela kwe-esterification kunye ne-oyile ende enamafutha e-asidi (TOFA), i-pentaerythritol kunye ne-PA njengezixhobo eziphambili, kwaye emva koko i-emulsifier AE 300 yongezwa ukufumana i-lotion yamanzi i-alkyd dispersion.I-aqueous polyurethane prepolymer yalungiswa kwi-diol dehydrated, isophorone diisocyanate kunye ne-aqueous monomer 2,2-dihydroxymethylpropionic acid (DMPA).I-Silicon acrylic polyurethane lotion yalungiswa ngokusebenzisa i-TEA njenge-agent engathathi hlangothi, yongeza i-acrylic monoma, i-emulsifier, i-agent yokudibanisa i-silane, i-initiator kunye ne-chain extender.I-silicone ye-acrylic polyurethane eguquliweyo yokugquma i-alkyd yamanzi yalungiswa nge-alkyd dispersion enamanzi kunye ne-silicone acrylic polyurethane lotion njengezinto eziphambili zokwenza ifilimu.
