PU hoseuyePA hosemhando mbiri dzakakurumbira dzemahosi anoshandiswa kune akasiyana maapplication.Nepo ese ari maviri achishandira chinangwa chemvura kana kufambisa kwemhepo, vane mimwe misiyano yakasiyana maererano nemidziyo yavo uye kuita kwavo.
Mumwe mutsauko unoonekwa pakati pePU hose nePA hose kuoma kwavo.PU hoses yakapfava kana ichienzaniswa neyavo PA.Uku kupfava kunoita kuti maPU hoses awedzere kuchinjika uye nyore kufambisa, achibvumira kuisirwa nyore uye kushandiswa munzvimbo dzakasimba.Kune rimwe divi, PA hoses ine kuomarara kwepamusoro, izvo zvinoita kuti iwedzere kuomarara uye isingachinjike.
Mumwe mutsauko wakakosha pakati pePU hose nePA hose une chekuita nekupisa kwavo uye nekumanikidza kuramba.PA hoses ane tembiricha yepamusoro uye kumanikidza kuramba zvichienzaniswa nePU machubhu.Izvi zvinoita kuti zvive zvakakodzera kune zvikumbiro apo kuendeswa kwemvura inopisa kana magasi kunobatanidzwa, pamwe chete nepamusoro-kudzvinyirira masisitimu.Kusiyana neizvi, maPU hoses haapikisane nekupisa kwakanyanya uye kumanikidza, kudzikamisa kushandiswa kwavo mumamiriro ezvinhu akadaro.
PU hoses inozivikanwa nekunaka kwayo abrasion kuramba.Ivo vanogona kutsungirira kusakara uye kubvaruka, zvichiita kuti ive yakanakira maapplication apo hose inosangana neyakaomarara kana kusangana nekufamba.Ichi chivakwa chePU hoses inochengetedza kusimba kwavo uye hupenyu hurefu, ichivapa mupendero pamusoro pePA hoses maererano nehupenyu hurefu.
Panyaya yekupikisa kwemakemikari, ese maPU nePA hoses anoratidza kuramba kwakanaka kune akasiyana siyana emakemikari.Ivo vanogona kumira kuratidzwa nemafuta, zvinonyungudutsa, asidhi, uye alkalis, zvichiita kuti ive yakakodzera kune akasiyana maindasitiri ekushandisa.Nekudaro, zvakakosha kuti uzive kuti kupikisa kwakananga kune mamwe makemikari kunogona kusiyana zvichienderana nekuumbwa kwepombi, saka zvakakosha kuti usarudze mhando chaiyo yepombi kune yaunoda kushandiswa.
Kana zvasvika pakudhura-kushanda, PU hoses inowanzove yakachipa kana ichienzaniswa nePA hoses.Izvi zvinovaita sarudzo yakakurumbira yezvishandiso uko bhajeti rinonetsa.Pamusoro pezvo, PU hoses ine huremu huremu, izvo zvinoita kuti kubata uye kutakura kuve nyore uye nyore.
Muchidimbu, mutsauko uripo pakati pePU hose nePA hose uri mukuoma kwavo, tembiricha uye kumanikidza kuramba, abrasion kuramba, makemikari kuramba, uye mutengo-kushanda.Mapaipi ePU akapfava, anochinjika, uye anopa zvakanakisa abrasion kuramba, nepo PA hoses aine tembiricha yepamusoro uye kuramba kumanikidza.Sarudzo pakati pezviviri izvi zvinoenderana nezvinodiwa chaizvo zvekushandisa, senge tembiricha, kudzvanywa, uye chimiro chemvura kana gasi riri kutamiswa.
