Mirathane® PUD|Ilaalinta deegaanka ee kaarboon-hoose waxay taageertaa hadhka cagaaran ee PUD

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 polyurethane 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, caabbinta kulaylka fiican iyo sifooyinka kale, waxaa loo isticmaali karaa noocyo kala duwan oo isku dhafan oo substrate ah, oo si ballaaran loo isticmaalo xabagta kabaha, xabagta gudaha baabuurta, caagagga vacuum, xabagta qoryaha iyo beeraha kale, U1115H. U1115, U1115L waa caadiga ah saddex anionic waterborne polyurethane kala firdhiyey, kuwaas oo U1115H si gaar ah ugu habboon xaaladaha codsiga iska caabinta kulaylka bilowga ah, U1115L gaar ahaan ku habboon 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, sababtoo ah faa'iidooyinka badan ee xabagta polyurethane ee biyaha, isticmaalkoodu wuxuu noqday mid aad u ballaaran, waxaana jira noocyo badan oo kala duwan.Sida laga soo xigtay saadaasha khubarada ku habboon, baahida loo qabo xabagta synthetic ee Shiinaha ayaa leh suuq ballaadhan, iyo xabagta polyurethane ee biyaha laga dhaliyo 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.Shiinaha ayaa diiradda saari doona 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 kulul ee PU ee firfircoon, koollada qaab dhismeedka PU-ga waxqabadka sare leh iyo koollada polymer polyisocyanate ee kharash yar, si heerka guud ee koollada PU ee Shiinaha ay u gaarto heerka sare ee hadda adduunka.
