Chii chinonzi Polyurea Coating uye Polyurethane Coatings
Polyurea Coating uye Polyurethane Coatings Polyurea coating Polyurea coating inonyanya maviri-zvikamu sisitimu yakavakirwa paAmine yakamiswa prepolymer yakabatanidzwa neIsocyanate inoumba urea linkages. Iko kuyambuka pakati pe reactive mapolymers kunoitika nekukasira kumhanya pane ambient tembiricha. Kazhinji kuita uku hakudi chero catalyst. Sezvo Pot-hupenyu hwekupfeka kwakadaro huri mukati memasekondi; yakakosha mhando yePlural Component spray pfuti inodiwa kuita application.

Chii chinonzi Moisture-cured polyurethane
Chii chinonzi Moisture-cured polyurethane Moisture-cured polyurethane is one-part polyurethane kuti kurapa kwayo kunotangwa hunyoro hwezvakatipoteredza. Iyo munyoro-inorapika polyurethane inonyanya kuve neisocyanate-yakamiswa pre-polymer. Mhando dzakasiyana dzepre-polymer dzinogona kushandiswa kupa inodiwa pfuma. Semuyenzaniso, isocyanate-yakapera polyether polyols inoshandiswa kupa yakanaka kuchinjika nekuda kwekudzika kwayo kwegirazi tembiricha. Kubatanidza chikamu chakapfava, senge polyether, uye chikamu chakaomarara, senge polyurea, inopa kuomarara kwakanaka uye kuchinjika kwejasi. Uyezve, zvivakwa zvinodzorwawo neVerenga Zvimwe…
Maitiro maviri ekugadzira machira ane akasarudzika mar resistance
Pane nzira mbiri dziripo dzekugadzira machira ane akasarudzika mar resistance. Dzinogona kuomeswa zvakakwana zvokuti chinhu chinoparadza hachipindi kure kumusoro; kana kuti Vanogona kuitwa elastic zvakakwana kuti vadzoke mushure mekunetseka kwekukanganisa kwabviswa. Kana iyo yekuomarara zano yakasarudzwa, iyo yekupfekedza inofanira kunge ine hushoma kuomarara. Zvisinei, zvipfeko zvakadaro zvinogona kukundikana nekuputsika. Firimu kuchinjika chinhu chakakosha chinokanganisa kuramba kwekutyoka. Kushandisa 4-hydroxybutyl acrylate paneVerenga Zvimwe…
