Zvinhu zvinokonzeresa polyurethane, dzakadai seMXS-6 (DC-193), dzinokosha mukugadzirwa kwemasora epolyurethane (PU), chinhu chakakosha muindasitiri yeshangu. Izvi zvinokonzeresa, zvinosanganisira silicone surfactants, zvinoshandiswa muindasitiri, zvakakosha pakugadzira foam yakasimba yepolyurethane, kunyanya mukugadzira shangu. Dzinoita basa rakakosha mukusimudzira hunhu hwemasora ePU, zvichiita kuti akwanise mhando dzakasiyana dzeshangu dzinosanganisira shangu dzemazuva ese, shangu dzekuchengetedza, uye shangu dzemitambo.
Basa guru re polyurethane catalysts nderekukurumidzira makemikari ari pakati pe isocyanates ne polyols, izvo zvinoumba polyurethane. Kuita uku kwakakosha pakugadzira chimiro chefuro re PU soles, zvichivapa hunhu hwakasiyana hwakadai sekusimba, kutwasuka, uye kunyudzwa kweshock. MXS-6 (DC-193), sezvo iri silicone surfactant, inobatsira kudzikamisa chimiro chefuro, ichivimbisa kunaka uye kushanda zvakanaka kwe PU soles.
Mushangu dzisingawanzoonekwi, shangu dzepolyurethane dzinopa nyaradzo isina muganho uye kuchinjika. Basa remuchina wekusimbisa muviri mukuona kuti furo rakatsetseka uye rakafanana rinoshandura kushangu dzinopa kuchinjika kwakaita seganda uye pamusoro paro pakanaka. Izvi zvinoguma neshangu dzisingangogadziki kwenguva refu chete asiwo dzinofadza runako, dzichienderana nemaitiro uye zvinodiwa zvekunyaradzwa kwevanopfeka shangu dzisingawanzoonekwi.
Kune bhutsu dzekuchengetedza, kusimba uye hunhu hwe polyurethane solids dzinobata kuvhunduka kwakakosha. Zvishandiso izvi zvinoita kuti bhutsu dzePU dzive nechimiro chefuro chakasimba chinokwanisa kutsungirira mamiriro akaomarara uye kudzivirira tsoka dzemunhu akapfeka. Kugona kwezvishandiso izvi kubata kuvhunduka kunobatsira kuderedza kukanganiswa kwetsoka nemajoini, izvo zvinonyanya kukosha kune vanhu vanoshanda munzvimbo dzinonetsa. Dziviriro iyi, pamwe chete nekusimba kwe PU solids, inoita kuti bhutsu dzekuchengetedza dzive dzakavimbika uye dzinogara kwenguva refu.
Shangu dzemitambo dzinoda hunhu hwepamusoro-soro hwekushanda, izvo zvinowedzerwa zvakanyanya ne polyurethane catalysts. Kuchinjika uye kusimbaradzwa kunopihwa nePU soles zvakakosha kune shangu dzemitambo, zvichipa rutsigiro rwuri nani uye zvinoderedza kukanganiswa kwetsoka panguva yemabasa epamusoro-soro. MaCatalysts akaita seMXS-6 (DC-193)Ita shuwa kuti pasi petsoka dzinochengetedza chimiro chadzo uye mashandiro adzo, kunyangwe mumamiriro ezvinhu akaoma ekushandisa mitambo.
Uyezve, jira repolyurethane rinogadzirwa neaya macatalyst rakareruka, zvichiita kuti shangu dzinyarare uye dzishande zvakanaka. Hunhu uhwu hwakareruka hunobatsira pamhando dzese dzeshangu, kubva kushangu dzisingawanzoitiki kusvika kushangu dzemitambo uye dzekuchengetedza, zvichideredza kuneta uye zvinowedzera kupfekwa kwese.
Muchidimbu, macatalyst epolyurethane akadai seMXS-6 (DC-193) akakosha pakugadzirwa kwemasora ePU emhando yepamusoro anoshandiswa mumhando dzakasiyana dzeshangu. Anovimbisa kugara kwenguva refu, kunyaradzwa, kubatwa neshock, uye hunhu hwakareruka hwemasora, zvichizadzisa zvinodiwa zvakasiyana-siyana zvevagadziri veshangu nevatengi. Kushandiswa kwecatalyst idzi mukugadzirwa kunoita kuti pave nezvigadzirwa zveshangu zvepamusoro zvinopa vanopfeka shangu dzisina kurongeka, vatambi, uye vanhu vanoda shangu dzakachengeteka, zvichiita kuti polyurethane ive chinhu chinosarudzwa muindasitiri yeshangu.
