Desmodur RE:Dzidza nezve mashandisirwo uye mabhenefiti eisocyanates
Desmodur REchigadzirwa chechikamu cheisocyanate, chakanyatso kutsanangurwa CAS 2422-91-5. Isocyanates zvinhu zvakakosha mukugadzirwa kwezvinhu zvakasiyana-siyana zve polyurethane, uye Desmodur RE haina mutsauko. Ichi chinyorwa chine chinangwa chekupa kunzwisisa kwakadzama kweDesmodur RE, mashandisiro ayo uye zvakanakira zvainopa mumashandisirwo akasiyana.
Desmodur REis an aliphatic polyisocyanate yakavakirwa pahexamethylene diisocyanate (HDI). Iyo inonyanya kushandiswa sechinhu chakaomesesa muchiedza-yakagadzika polyurethane coatings uye adhesive maumbirwo. Iyo yakasarudzika chemistry yeDesmodur RE inoita kuti ive yakanaka kune maapplication anoda epamusoro-kuita machira ane yakanakisa mamiriro ekunze uye makemikari kuramba. Pamusoro pezvo, kugarisana kwayo nemhando dzakasiyana dzema polyols uye zvinonyungudutsa zvinowedzera kuwedzera mashandiro ayo mumhando dzakasiyana.
Imwe yemabhenefiti makuru eDesmodur REiko kugona kwayo kupa kusimba kwakanyanya uye UV kuramba kune machira. Izvi zvinoita kuti zvive zvakanyanya kukodzera kune zvekunze zvikumbiro, uko kuratidzwa kune yakaoma mamiriro ezvakatipoteredza kunogona kukanganisa mashandiro echinyakare machira. Ingave ichishandiswa mumachira emotokari, machira ekugadzirisa maindasitiri kana kupedzisa kwekuvaka, Desmodur RE inoita basa rakakosha mukuvandudza hupenyu hurefu uye kutaridzika kwenzvimbo dzakavharwa.
Pamusoro pebasa rayo mukupfeka, Desmodur RE inoshandiswawo mukugadzirwa kwemhando yepamusoro yekunamira. Kukurumidzira kurapa kwayo zvimiro uye kunamatira kwakanakisa kune akasiyana ma substrates anoita kuti ive chinhu chakakosha muzvigadzirwa zvekunamira, laminating adhesives uye sealant maumbirwo. Desmodur RE adhesives inokwanisa kumirisana nemechini kusagadzikana uye zvakatipoteredza zvinhu, zvichivaita sarudzo yekutanga yekuda bonding application mumaindasitiri akasiyana.
Pamusoro pe,Desmodur REinopa maformulators kugona kuchinjika kugadzirisa zvimiro zve polyurethane coatings uye zvinonamira kune zvakanangana nezvinodiwa. Nekugadzirisa zviyero zvekugadzirisa uye kubatanidza Desmodur RE, huwandu hwakawanda hwemaitiro ekuita hunogona kuwanikwa, kusanganisira kuoma, kushanduka uye makemikari kuramba. Iyi nhanho yekugadziriswa inoita kuti vagadziri vakwanise kusangana nezvinodiwa zvakasiyana zvevashandisi vekupedzisira muzvikamu kubva kumotokari uye aerospace kusvika kuvaka uye zvivakwa.
Zvakakosha kuziva kuti nguvaDesmodur REinopa akawanda mabhenefiti maererano nekuita uye kuita kwakasiyana-siyana, nekuda kweiyo reactive hunhu hweisocyanates, kubata kwakaringana uye kuchengetedza kunofanirwa kucherechedzwa. Kuratidzwa kune isocyanates kunogona kuunza njodzi dzehutano, saka zvakakosha kutevedzera yakakurudzirwa nhungamiro yekuchengetedza uye kushandisa yakakodzera midziyo yekudzivirira pakubata Desmodur RE uye zvimwe isocyanate-based zvigadzirwa.
Muchidimbu,Desmodur REchinhu chakakosha mukugadzirwa kwepamusoro-kushanda polyurethane coatings uye adhesives. Kusimba kwayo kwakasarudzika, UV kuramba uye kuita zvakasiyana-siyana kunoita kuti ive chinhu chakakosha mukugadzirwa kwemajasi uye anonamira kune akasiyana maapplication. Nekunzwisisa mashandisirwo uye mabhenefiti eDesmodur RE, vagadziri uye vashandi vekupedzisira vanogona kushandisa simba rayo rekugadzira zvinhu zvakasimba, zvinogara kwenguva refu uye zvepamusoro-soro zve polyurethane. Nekudaro, kana uchishanda nezvigadzirwa zveisocyanate, zvakakosha kukoshesa matanho ekuchengetedza kuve nechokwadi chekugara zvakanaka kwevashandi uye nharaunda.
