Ndeupi Musiyano Pakati PePolyurethane Uye Epoxy Resin?

1. Kufanana uye Kusiyana pakati pePolyurethane uye Epoxy Resin:

The Commonality:

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

2) Vese vane yakanaka tensile kuramba, hapana kuputika, hapana kudonha uye zvimwe zvivakwa;

3) Zvose zvine maitiro ekudzivirira kusvibiswa kune yakasimba acid, alkali, munyu uye zvakasiyana-siyana zvemafuta zvinhu;

4) Ose ane zvimiro zveguruva, kusapinda kwemvura, pamusoro kupfeka kuramba, inorema kumanikidza kuramba, kukanganisa kupikisa uye zvichingodaro;

Musiyano:

1) Polyurethane (PU) inonzi polyphenylene diisocyanate uye polyether polyol.Iyo yakabatana-yakabatana uye inorapwa pamberi pecatalyst 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 zviri mukati diisocyanate uye polyether polyol, uye inogona kushandiswa mukuputira emhando dzakasiyana dzemagetsi nemagetsi.

2) Epoxy resin inowanzo umbwa nebisphenol A epoxy resin, kuporesa mumiririri (amine kana acid anhydride), mubatsiri ajenti, filler, etc. Iine nguva yakareba yekuporesa pakupisa kwekamuri 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 kwepolyurethane 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 parts,makumbo eshangu, dehwe rekugadzira, waya netambo uye nhengo dzekurapa dzekugadzira, nezvimwewo;

Nekugadzira zvigadzirwa zvepurasitiki, kupfeka-resistant synthetic rubber products, synthetic fibers, dzakaomarara uye dzinochinjika furo 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 zvinogona kugadzirwa zvinoenderana nezvinodiwa nevatengi, senge mutete-layer coating, 1-5mm gobvu inodzika-yepamusoro pasi, anti-skid uye kupfeka-inodzivirira pasi, dhaka pasi, 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 mwaranzi, uye inoshanduka yero pasi pemwaranzi yakasimba ye ultraviolet, ndiko kuti, kupera, asi haizoparari uye haizokanganisa 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.
