Ni irihe tandukaniro riri hagati ya Polyurethane na Epoxy Resin?

1. Ubusanzwe no Gutandukanya Polyurethane na Epoxy Resin:

Ibisanzwe:

1) Polyurethane na epoxy resin ni ibice bibiri, kandi ibikoresho nuburyo bwo gukora burasa;

2) Byombi bifite imbaraga zo guhangana neza, nta guturika, nta kugwa nibindi bintu;

3) Byombi bifite imiterere yo kurwanya ruswa irwanya aside ikomeye, alkali, umunyu nibintu bitandukanye byamavuta;

4) Byombi bifite imiterere yumukungugu, utarinda amazi, kurwanya kwambara hejuru, kurwanya umuvuduko ukabije, kurwanya ingaruka nibindi;

Itandukaniro:

1) Polyurethane (PU) ni polifenilene diisocyanate na polyether polyol.Irahujwe kandi ikira imbere ya catalizator triethylene diamine kugirango ikore polymer ndende.Ugereranije na epoxy resin, ni uburozi.

Polyurethane ifite ibiranga kwifata neza, kubika no guhangana nikirere.Ubukomezi burashobora guhinduka muguhindura ibiri muri diisocyanate na polyether polyol, kandi irashobora gukoreshwa mugupakira ibikoresho bitandukanye bya elegitoroniki namashanyarazi.

2) Epoxy resin muri rusange igizwe na bispenol A epoxy resin, imiti ikiza (amine cyangwa aside anhydride), umukozi wungirije, uwuzuza, nibindi. Ifite igihe kirekire cyo gukira mubushyuhe bwicyumba kandi irashobora gukira nubushyuhe.Nyuma yo gukira, ifite imbaraga zo guhuza hamwe no gukomera.Mubisanzwe, ni binini kandi birashobora gukorwa mu mucyo kugirango ushiremo amashanyarazi na diode.

Polyurethane ifite uburyo bwiza bwo guhangana nikirere, ntigucika ku bushyuhe bwo hejuru kandi buke, kandi bihenze gato.

2.koresha polyurethane na epoxy resin:

1) Igikoresho cya polyurethane:

Polyurethane resin ni ibikoresho bya polymer bifite imbaraga nyinshi, birwanya amarira, kwambara birwanya nibindi biranga;

Byakoreshejwe nkaumuzingo,imikandara, amabati, ibice by'imodoka,inkwetouruhu rwubukorikori, insinga ninsinga hamwe ningingo zubuvuzi, nibindi.;

Kugirango habeho ibicuruzwa bya pulasitiki, ibikoresho byo mu bwoko bwa reberi idashobora kwihanganira kwambara, fibre synthique, fibre ikomeye kandi yoroheje, ibicuruzwa bifata neza, ibifatika hamwe nibindi,.;

Ikoreshwa mukurangiza hejuru yibiti bitandukanye, ibikoresho bya shimi, ibikoresho byitumanaho nibikoresho hamwe nuburyo butandukanye bwo gutwara.

2)Epoxy resin: irashobora kandi gukoreshwa mubitambaro, ibifatika, ibikoresho byinshi, nibindi

Epoxy resin coating ni ubwoko bwimbaraga nyinshi, zidashobora kwambara kandi hasi nziza, ifite ibyiza byo kutagira ikidodo, imiterere ikomeye, kurwanya imiti myiza, kurwanya ruswa, kutagira umukungugu, kubungabunga neza hamwe nigiciro gito cyo kubungabunga.

Gahunda zitandukanye zirashobora gutegurwa ukurikije ibyo umukiriya asabwa, nk'igipfundikizo cyoroshye, igorofa ya 1-5mm yikigero cyo hasi, irwanya skid kandi irwanya kwambara, hasi ya minisiteri, anti-static, anti-ruswa, nibindi.

Ibicuruzwa birakwiriye ahantu hatandukanye, nk'amahugurwa, ibyumba bya mudasobwa, ububiko, laboratoire, icyumba, ibyumba byo gukoreramo, amahugurwa, n'ibindi.

3. Ikoti yambere yambere ikwiriye gukoreshwa hanze, mugihe iyanyuma ikwiriye gukoreshwa murugo;

Intege nke cyangwa ibibi byanyuma ni uko itinya imirasire ikomeye ya ultraviolet, kandi izahinduka umuhondo munsi yimirasire ikomeye ya ultraviolet, ni ukuvuga izimangana, ariko ntizangirika kandi ntizagira ingaruka kumikoreshereze;

Nyamara, ibyambere byateye imbere cyane mukurwanya ikirere kurusha icya nyuma, cyane cyane igihe cyumuhondo cyambere cyabaye kirekire cyane kuruta icya nyuma, kubwibyo rero akenshi bikoreshwa mubisabwa kubaka hanze.
