Codsiga Polyurethane

Polyurethane waxaa loo isticmaali karaa samaynta caagadaha, caag, fiyuusyada, xumbo adag oo dabacsan, xabagta iyo dahaarka, iwm. Waxa loo isticmaali karaa qaybo kala duwan oo nolosha dadka ah waxayna leedahay codsiyo kala duwan.

1. Xumbo polyurethane:

U qaybsan xumbo poliurethane adag, xumbo poliurethane-adag ah iyo xumbo poliurethane dabacsan.Xumbo poliurethane adag ayaa inta badan loo isticmaalaa in lagu dhiso qalabka kuleylka kuleylka, qalabka kuleylka (xarumaha tuubooyinka, iwm., kuleylka kulaylka iyo isticmaalka maalinlaha ah) (sariiraha, fadhiga, iwm, joodariyaasha, qaboojiyaha, qaboojiyaha, iwm, lakabyada daboolka, iyo sabuuradaha, iwm. agabka xudunta u ah, iyo Gaadiidka (baabuur, diyaarado, baabuurta tareenada, barkimada, saqafka iyo alaabta kale).

2. elastomer polyurethane:

Elastomer Polyurethane wuxuu leeyahay faa'iidooyinka xoogga jilicsan ee wanaagsan, xoogga jeexjeexa, caabbinta saameynta, caabbinta abrasion, caabbinta cimilada, caabbinta hydrolysis, caabbinta saliidda iyo wixii la mid ah.Inta badan loo isticmaalo daahan alaabta (sida ilaalinta tuubooyinka, dhaqida, taayirada, rollers, gears, tuubooyinka, iwm), insulators, kabaha kabaha, iyo taayirada adag.

3. Walaxda polyurethane ee aan biyuhu lahayn:

Maaddada biyuhu ee polyurethane ayaa aad ugu habboon in la isticmaalo.Waxaa lagu qasi karaa goobta waxaana lagu daaweeyaa heerkulka caadiga ah iyo qoyaanka ka dib marka la daboolo, ka dibna lakabka biyuhu ee aan lahayn wax tol ah, caag caag ah iyo waxqabad wanaagsan ayaa la heli karaa.Oo ay fududahay in la hagaajiyo ka dib dhaawaca.Guud ahaan loo isticmaalo sida alaabta laamiga, qalabka orodka iyo garoonka, orodka, alaabta dhulka park, daaqadaha dahaarka kulaylka, iwm.

4. Daahan polyurethane:

Daboolka poliurethane wuxuu leeyahay adhesion xoog leh, iyo filimka dahaarka ayaa leh iska caabin aad u fiican, caabbinta biyaha iyo caabbinta kiimikada.Inta badan loo isticmaalo dahaarka alaabta guriga, dahaarka alaabta dhismaha iyo khadadka daabacaadda warshadaha.

5. Xabagta polyurethane:

Waxqabadka badeecada la daaweeyay waxaa lagu hagaajin karaa iyadoo la hagaajinayo saamiga isocyanate iyo polyol, si ay u gaarto adhesion sare ee substrate-ka, caabbinta biyaha aad u fiican, caabbinta saliidda iyo caabbinta kiimikada.Xabagta polyurethane waxaa inta badan loo isticmaalaa baakadaha, dhismaha, alwaaxyada, baabuurta, kabo samaynta iyo warshadaha kale.

6. Qalabka biomedical:

Polyurethane waxay leedahay biocompatibility aad u fiican, sidaas darteed si tartiib tartiib ah ayaa loo isticmaalaa sida walxaha biomedical.Waxa loo isticmaali karaa samaynta qalabka wadnaha ee macmalka ah, xididdada dhiigga ee macmalka ah, lafaha macmalka ah, hunguriga macmalka ah, kelyaha macmalka ah, xuubabka sifaynta macmalka ah, iwm.
