1. The CommonalityAnd DifferenceBpakatiPolyurethaneAnd EpoxyResin:

TheKufanana

1)Polyurethane uye epoxy resin zvikamu zviviri, uye midziyo uye nzira dzekushanda dzakafanana;

2)Ose ari maviri ane yakanaka tensile kuramba, hapana kutsemuka, hapana kudonha uye zvimwe zvivakwa;

3)Ose ari maviri ane hunhu hwekushongedzwa kwecorrosion kune yakasimba acid, alkali, munyu uye zvakasiyana-siyana mafuta zvinhu;

4)Ose ane hunhu hweisina guruva, isina mvura, kupikisa kupfeka kwepamusoro, kunorema kudzvinyirira kuramba, kukanganisa kupikisa uye zvichingodaro;

The Dkufungidzira:

1)Polyurethane (PU)polyphenylene diisocyanate uye polyether polyol.Iyo yakabatana-yakabatana uye     inorapwa pamberi pe catalyst triethylene diamine kuumba yakakwira polymer.Kana ichienzaniswa ne epoxy resin, ine muchetura zvakanyanya.

Polyurethane ine hunhu hwekunamira kwakanaka, insulation uye kuramba kwemamiriro ekunze.Iko kuoma kunogona kuchinjwa nekugadzirisa zvirimo zve diisocyanate uye polyether polyol, uye inogona kushandiswa mukurongedza zvezvakasiyana siyana zvemagetsi nemagetsi.

2)Epoxy resin kazhinji inoumbwa nebisphenol A epoxy resin, kurapa ajenti (amine kana acid anhydride), mubatsiri agent, filler, etc. Iine nguva yakareba yekuporesa mutembiricha yekamuri uye inogona kurapwa nekupisa.Mushure mekurapa, ine yakakwirira yekubatanidza simba uye kuoma.Kazhinji, yakakura uye inogona kuitwa pachena kuti ivhare ma modules emagetsi uye diode.

Polyurethane ine zvirinani kupikisa mamiriro ekunze, haina kuputika pakudziya kwepamusoro uye kwakaderera, uye inodhura zvishoma.

2.Kushandiswa kwe polyurethane uye epoxy resin:

1) Polyurethane resin:

Polyurethane resin i polymer zvinhu zvine simba rakawanda, kuramba kubvarura, kupfeka kuramba uye humwe hunhu;

Inoshandiswa serollers, conveyor mabhandi, hoses, auto zvikamu, makumbo eshangu, dehwe rekugadzira, waya netambo uyenhengo dzokurapa dzakagadzirwa, nezvimwewo;

Nekugadzira zvigadzirwa zvepurasitiki, kupfeka-resistant synthetic rubber zvigadzirwa, synthetic fibers, furo rakaomarara uye rinochinjika zvigadzirwa,zvinonamira uye machira, nezvimwewo;

Inoshandiswa kupedzisa pamusoro pehuni dzakasiyana-siyana, makemikari midziyo, telecommunication midziyo uye zviridzwa uye nzira dzakasiyana dzekufambisa.

2)Epoxy resin: inogona zvakare kushandiswa mumachira, zvinonamira, zvinosanganiswa zvinhu, nezvimwe.

Epoxy resin coating imhando yepamusoro-yakasimba, isingapfeki uye yakanaka pasi, ine zvakanakira isina musono, yakasimba magadzirirwo, yakanaka makemikari kuramba, anti-corrosion, guruva-proof, kugadzirisa kuri nyore uye yakaderera mutengo wekugadzirisa.

Zvirongwa zvakasiyana-siyana zvinogona kugadzirwa zvinoenderana nezvinodiwa nevatengi, senge mutete-layer coating, 1-5mm gobvu yekudzikamisa pasi, anti-skid uye kupfeka-inodzivirira pasi, pasi pevhu, anti-static, anti-corrosion pasi, nezvimwe.

Zvigadzirwa zvakakodzera nzvimbo dzakasiyana siyana, senge maworkshops, makamuri emakombuta, matura, marabhoritari, mawadhi, makamuri ekushanda, mashopu, nezvimwe.

3. Iyo yekare topcoat yakakodzera kushandiswa kwekunze, nepo iyo yekupedzisira yakakodzera kushandiswa kwemukati;

Kunyanya kushaya simba kana kukanganisa kwekupedzisira ndeyekuti inotya simba re ultraviolet nemwaranzi, uye inoshanduka yero pasi pesimba rakasimba re ultraviolet, kureva, kupera, asi haizoparari uye haizokanganisi kushandiswa;

Zvisinei, iyo yekare yakagadziridzwa zvakanyanya mukurwisana kwemamiriro ekunze kupfuura ekupedzisira, kunyanya nguva yeyero yekare yakareba kudarika iyo yekupedzisira, saka iyo yekare inowanzoshandiswa kune zvinodiwa zvekuvaka kunze.
