Isbeddelka horumarinta xabagta synthetic ee adduunka ayaa lagu muujiyay ilaalinta deegaanka iyo waxqabadka sare, iyada oo la raacayo xeerarka ilaalinta deegaanka ee sii kordheysa, wadamada horumaray waxay si xoog leh u horumariyaan koollada biyaha ku salaysan. Iyada oo ay ugu wacan tahay waxqabadka sare ee dhamaystiran ee xabagta poliurethane ee biyaha, waa mid u gaar ah dhammaan noocyada kala duwan ee xabagta biyaha, waxayna heleen fiiro gaar ah gudaha iyo dibadda sannadihii la soo dhaafay, gaar ahaan horumarinta iyo cilmi baarista waxqabadka sare ee xabagta polyurethane ee biyaha ayaa noqday mid kulul. mawduuca.
Biyo-baxa polyurethane (PUD) waa emulsion isku mid ah oo lagu sameeyay ku kala firdhinta poliurethane ee biyaha, kaas oo leh faa'iidooyinka VOC hooseeya, ur yar, aan guban, sifooyin farsamo oo aad u fiican, hawlgal ku habboon iyo farsamaynta. PUD waxaa si weyn loogu isticmaali karaa xabagta, maqaarka synthetic, dahaarka, khadadka iyo warshadaha kale.
Xabagta poliurethane ee biyaha sida isticmaalka koolo, oo leh firfircooni fudud, iska caabin kulayl aad u fiican iyo sifooyin kale, waxaa loo isticmaali karaa noocyo kala duwan oo isku xira substrate, oo si ballaaran loo isticmaalo xabagta kabaha, xabagta gudaha baabuurta, balaastiig vacuum ah, xabagta qoryaha iyo beeraha kale, U1115H. U1115, U1115L waa seddex anionic waterborne polyurethane kala firidhsan, kuwaas oo U1115H gaar ahaan ku haboon xaaladaha codsiga iska caabinta kuleylka bilowga ah, U1115L waxay si gaar ah ugu habboon tahay xaaladaha leh shuruudaha viscosity sare.
Polyurethane Waterborne waxay leedahay tiro balaadhan oo ah guryaha jirka ka dib markii filimka, oo leh iska caabin qabow wanaagsan, caabin dareere ah, samaynta filimada, iska caabin tortuous, caabbinta xoqin qalalan iyo qoyan, adhesion iyo faa'iidooyinka kale, waxaa loo isticmaali karaa sida daahan ee substrates kala duwan, si ballaaran loo isticmaalo. ee wakiilka dhamaystirka maqaarka, dahaarka dharka, maqaar synthetic iyo beeraha kale.
Marka la soo koobo, iyada oo ay ugu wacan tahay faa'iidooyinka badan ee xabagta polyurethane ee biyaha, isticmaalkoodu wuxuu noqday mid aad u ballaaran, waxaana jira noocyo badan oo badan. Sida laga soo xigtay saadaasha khubarada ku lug leh, baahida loo qabo xabagta synthetic ee Shiinaha ayaa leh suuq ballaadhan, iyo xabagta polyurethane ee biyaha ka soo baxa ayaa ku guuleystay suuqa iyaga oo leh waxqabadkooda sare iyo ilaalinta deegaanka iyo badbaadinta tamarta, wax soo saarkooda iyo codsigooda ayaa si degdeg ah u ballaarinaya oo kor u qaadaya. . Dabcan, cilladaheeda ayaa sidoo kale u baahan in si qoto dheer loo xalliyo. Shiinuhu wuxuu diiradda saari doonaa horumarinta xabagta polyurethane ee biyaha, waxayna soo bandhigi doontaa qalabka muhiimka ah ee ku salaysan tiknoolajiyada is-horumariyay si loo horumariyo "cagaaran" dareeraha ku salaysan, aan jaalaha lahayn, kulaylka u adkaysta iyo waxqabadka sare ee PU; Samee xabagta dhalaalaysa ee PU-ga firfircoon, koollada qaab dhismeedka PU-da ee waxqabadka sare leh iyo koolada polymer polyisocyanate ee kharash yar, si heerka guud ee koollada PU ee Shiinaha ay u gaadho heerka horumarsan ee hadda adduunka.
