Foam yeHigh Resilience (HR) ifoam yepamusoro-soro yepolyurethane inosanganisa kusimba kwakanaka uye kusimba pamwe nekunyaradzwa kwakanyanya uye rutsigiro. Kusiyana nemafuro echinyakare, furo yeHR inopora nekukurumidza mushure mekudzvanywa, zvichiita kuti irambe yakagadzikana uye igare kwenguva refu. Hunhu uhwu hunoita kuti furo yeHR ive sarudzo yakakurumbira kune akasiyana mashandisirwo anoda kucheneswa, akadai sematiresi, fenicha, zvigaro zvemotokari, nezvimwe zvigadzirwa zvinotarisa kunyaradzwa.
Hunhu hweHigh-Resilience Foam
Foam yeHR ine hunyoro hwakasiyana uye inotsungirira. Inokwanisa kupa rutsigiro rwakanaka ukuwo ichipa kunzwa kwakasununguka. Foam idzi dzine hunhu hwepamusoro hunovandudza kugara kwenguva refu uye kunyaradzwa, zvichiita kuti dzikurumidze kudzokera kuchimiro chadzo chepakutanga mushure mekudzvanywa. Kugona kwefoam yeHR kupora nekukurumidza kwakakosha kune zvigadzirwa uko kunyaradzwa kwenguva refu uye mashandiro azvo zvakakosha.
Pamusoro pezvo, furo reHR rinowanzogadzirwa nechimiro chemasero akanaka, izvo zvinoita kuti rive rakareruka uye rakanaka kwazvo rekuchengetedza. Chimwe chezvakanakira zvikuru zvefuro reHR ndechekuti rinogara kwenguva refu. Rinogona kutsungirira kudzvanywa kakawanda pasina kurasikirwa nehunhu hwaro hwekutsigira, zvichiita kuti rive sarudzo yakakurumbira yefenicha nemagumbeze ayo anoshandiswa kakawanda.
Kufambira mberi muhunyanzvi hweHR foam kunosimbisawo kuchengetedzeka. Vagadziri vava kushandisa nzira dzisingakuvadzi nharaunda mukugadzira, kubva pakushandisa zviwanikwa zvinogona kushandiswazve kusvika pakugadzira foam dzinoshandiswazve zviri nyore.
Basa reMXC-A1mukugadzirwa kweFoam yeHR
Polyurethane catalyst MXC-A1 (BDMAEE) inoita basa rakakosha mukugadzirwa kweHR foams nekusimudzira reaction yeurea (water-isocyanate), iyo inokosha pakuita kwefuro remafuro epolyurethane anochinjika uye akaomarara. Catalyst iyi ine catalytic activity yakakura uye sarudzo, zvichiita kuti ive chinhu chakakosha mukugadzirwa kweHR foams dzemhando yepamusoro nezvimwe zvigadzirwa zvefuro zvinochinjika.
MXC-A1 inonyanya kubatsira mukugadzirwa kwefoam yeHR nekuti inowedzera kuumbwa kwefoam. Inokurudzira kuumbwa kwefoam pakati peisocyanate nemvura, iyo inoumba gasi reCO2, iro rinowedzera furo. Maitiro aya akakosha kuti pave nehuwandu hwefoam uye chimiro chayo. Basa guru reMXC-A1 rinoita kuti furo rishande zvakanaka, zvichikonzera kuti furo rigare rakanaka uye hunhu hwakanaka hwekushanda huve nani.
Pamusoro pekushanda kwayo zvakanaka kwekuita furo, MXC-A1 inobatsira kugadzira furo rine simba rakasimba, rinogara kwenguva refu uye rinochinjika. Nekunyatso dzora maitiro ekuita, MXC-A1 inobatsira kuwana chiyero chakakwana pakati pekupfava nerutsigiro mumafuro eHR. Izvi zvinoita kuti ive sarudzo yakakura yemashandisirwo ayo kusimba kwakanyanya uye kunyaradzwa kwenguva refu kwakakosha.
MXC-A1mune Mamwe Mashandisirwo Efoam Anochinjika
Kunyange hazvo MXC-A1 ichinyanya kushanda muHR foam, kushandiswa kwayo kwakasiyana-siyana kunosvika kune akasiyana-siyana emafoam anochinjika. Iyi catalyst inoshandiswawo mukugadzira zvigadzirwa zveRIM (reaction injection molding), ichipa basa rakawanda uye sarudzo inogona kuwedzera hunhu hwema mechanical hwezvikamu zvefoam zvakaumbwa. Kugona kwayo kukurudzira isocyanate reaction isina hwema hushoma uye emissions inoita kuti ive sarudzo inokwezva vagadziri vari kutsvaga kuvandudza mhando uye nharaunda yezvigadzirwa zvavo zvefoam.
Kuvandudza Kugara Kwefuro Nekuputira Polyethylene Fiber
Kuti iwedzere kuvandudza mashandiro efoam yeHR, kuputira nefiber yepolyethylene kunowanzo shandiswa. Rutivi urwu rwekuwedzera runowedzera kupfava, kugara kwenguva refu, uye kutsetseka kwefoam, zvichigadzira kunzwa kwakanaka ukuwo zvichidzivirira kusimba kwefoam. Kuputira uku kunoshanda sechidziviriro chinodzivirira chinobatsira kuchengetedza chimiro chefoam nekufamba kwenguva, zvichiita kuti foam irambe iine chimiro chayo uye kunyaradzwa kwenguva yakareba.
Mhedziso
Furo rinogara kwenguva refu rinomiririra kunyaradzwa uye kushanda zvakanaka muindasitiri yefuro repolyurethane. Nerubatsiro rwezvishandiso zvepamusoro zvakaita seMXC-A1, vagadziri vanogona kugadzira furo rinopa kusimba kwakanyanya, kusimba, uye kugara kwenguva refu. Basa reMXC-A1 rekugadzirisa zvinhu zvakanyanya uye kusarudza kunoita kuti ive chinhu chakakosha mukugadzira furo reHR risingangogadziki uye rinotsigira asiwo rinogara kwenguva refu uye rinoshanda zvakanaka. Ingave ichishandiswa mufenicha, magumbeze, kana mashandisirwo emotokari, furo reHR rinoramba richisangana nezvinodiwa nevatengi vemazuva ano, richipa kunyaradzwa kwenguva refu uye kushanda zvakanaka..
