Mafuro epolyurethane zvinhu zvakakosha mumaindasitiri akasiyana-siyana nekuda kwehunhu hwawo hunoshandiswa zvakasiyana-siyana, kubva pakuputira kusvika pakurongedza. Chinhu chinoshandiswa mukugadzira furo chinoita basa guru mukutsanangura hunhu uhwu.MXC-37, inozivikanwawo se2-[2-(Dimethylamino)ethoxy]ethanol (DMAEE), chinhu chakakosha che tertiary amine catalyst chakakurumbira nekuda kwekushanda kwayo kwakanaka mukugadzira polyurethane rigid foam, kunyanya mumafomula anoda mvura yakawanda.
Zvinhu Zvikuru zveMXC-37
MXC-37 inozivikanwa nekushanda kwayo kukuru kwefuro, zvichiita kuti ive yakanaka kugadzira mafoam ekurongedza ane huwandu hwakaderera. Kugona kwayo kushanda zvinobudirira mumasystem ane mvura yakawanda kunobvumira kugadzirwa kwema open-cell structures, ayo anonyanya kutsvakwa mu spray polyurethane foam (SPF). Kusiyana netsika dzechinyakare.zvinokonzeresa zvinobva kumaamine, Maumbirwo akasiyana emakemikoro eMXC-37, anosanganisira hydrogen inoshanda, anoita kuti ikwanise kubatana nema polymer matrix nemakemikari. Kubatanidzwa uku kunoderedza zvakanyanya kunhuhwirira kwemaamine kunobatanidzwa nema polyurethane foams, zvichikonzera chigadzirwa chiri nyore kushandisa.
Kushandiswa Kwazvo uye Kuchinja-chinja
MXC-37 haingogumiri pakugadzira furo rakasimba chete; inowanikwawo mukugadzira furo rakasimba uye polyether polyurethane soft block foam. Chitarisiko chayo chisina ruvara kana yero yakajeka patembiricha yemumba, pamwe chete nekunyunguduka kwayo mumvura, chinoita kuti ive sarudzo iri nyore kune vanogadzira. Mukushandisa kweSPF, MXC-37 inogona kushandiswa sechinhu chikuru chinobatsira, asi inoshandawo sechinhu chakanaka chinobatsira kana ikasanganiswa nezvimwe zvinhu zvinoita kuti furo riwedzere kunaka, zvakaita sezviri paBDMAEE. Nekushandisa MXC-37, vagadziri vanogona kuderedza kuvimba nezvinhu zvinoita kuti furo riwedzere, zvichideredza mari yekugadzira uye kuvandudza mhando yefuro.
Mabhenefiti Ezvakatipoteredza uye Ekunzwisisa
Chimwe chezvinhu zvinonyanya kukosha zveMXC-37 kugona kwayo kuderedza hwema hwechigadzirwa chepolyurethane chapera. Izvi zvinoitwa kuburikidza nekushandiswa kwemakemikari eMXC-37 muchimiro chepolymer, izvo zvinoderedza huwandu hweamine hunokonzera hwema hunhu hwacho. Nekuda kweizvozvo, chigadzirwa chekupedzisira hachingori chekuchengetedza nharaunda chete asiwo chinonakidza kune vatengi nevanoshandisa.
Mukupedzisa, MXC-37 chinhu chinobatsira zvikuru uye chinoshanda zvakanaka chinopa mabhenefiti makuru mukugadzirwa kwefuro rinogara riripo repolyurethane. Kushanda kwayo pakuburitsa furo rakawanda, kuenderana nemafuta ane mvura yakawanda, uye kugona kwayo kuderedza hwema zvinoita kuti ive sarudzo yakanaka kwazvo yekushandiswa kwakasiyana-siyana muindasitiri yepolyurethane. Ingave yakashandiswa yoga kana semushonga unoshanda pamwe chete, MXC-37 yakagadzirira kuwedzera mashandiro uye kukwezva kwemafuro epolyurethane.
