Zvinhu zvinokonzeresa makemikari ePolyurethane, zvakaita seMXC-T, inoita basa rakakosha mukugadzirwa kwemhando dzakasiyana dzemafuro epolyurethane, kusanganisira mafuro akapfava epolyether, mafuro akaumbwa, mafuro akapfava, uye mafuro akaomarara. Pakati peizvi, furo rakapfava repolyurethane rinonyanya kushandiswa mumaindasitiri akasiyana-siyana, kunyanya muchikamu chemotokari. Hunhu hwaro hwakasiyana hunoita kuti rive chinhu chakanakira zvigadzirwa zvakasiyana-siyana zvevatengi nevemabhizinesi.
Foam yepolyurethane yakapfava inokosheswa nekuda kwehunyanzvi hwayo hwepamusoro hwekushongedza, izvo zvinoita kuti ive chinhu chinodiwa pamibhedha, fenicha, mukati memotokari, makapeti, uye kurongedza. Chinhu ichi chinogona kugadzirwa muchimiro chero chipi zvacho uye kuomarara, zvichienderana nezvinodiwa uye zvaunofarira. Kugona kugadzirisa foam yepolyurethane yakapfava kunoita kuti ikwane chaizvo nezvinodiwa zvemashandisirwo akasiyana-siyana, zvichiwedzera kushanda kwayo uye kukwezva kwayo.
Chimwe chezvakanakira zvikuru zvefuro rakapfava repolyurethane ihuremu hwaro. Hunhu uhwu hahungoiti kuti zvive nyore kubata nekuisa chete asiwo hunobatsira mukuderedza huremu hwezvigadzirwa pazvinoshandiswa. Semuenzaniso, mukushandiswa kwemotokari, huremu hwefuro hunogona kutungamira mukuvandudzwa kwekushandisa mafuta uye kushanda zvakanaka, zvichienderana nezvinangwa zveindasitiri zvekuchengetedza simba uye kushanda zvakanaka kwesimba.
Kugara kwenguva refu ndeimwe mukana mukuru wefuro rakapfava repolyurethane. Rinoramba rakaita chimiro charo uye mashandiro aro nekufamba kwenguva, kunyangwe richishandiswa kakawanda. Kugara kwenguva refu uku kunoita kuti rive sarudzo inodhura zvishoma kune vagadziri nevatengi, sezvo richiwedzera hupenyu hwezvigadzirwa uye rinoderedza kudiwa kwekutsiviwa kakawanda. Kana tichitarisa mukati memotokari, zvinhu zvinogara kwenguva refu zvinosimbisa hurefu hwezvigaro, nzvimbo dzekutsamira maoko, uye nzvimbo dzekutsamira musoro, zvichiita kuti kutyaira kuve nyore.
Rutsigiro nenyaradzo zvinonyanya kukosha kana zvasvika pakushandiswa mumagumbeze nemidziyo. Foam yakapfava yepolyurethane inopa chiyero chakanaka chehunhu uhwu, zvichiita kuti matiresi, mapillow, nemidziyo yakagadzirwa neupholstery zvive nyore uye zvinotsigira. Kugona kwayo kuenderana nechimiro chemuviri uku ichipa rutsigiro rwakakwana kunobatsira mukuderedza kumanikidzwa uye kukurudzira kurara zvakanaka uye kugara zvakanaka.
Pamusoro pehunhu hwayo hwepanyama, furo repolyurethane rakapfava rinobatsirawo nharaunda kana richishandiswa sechinhu chinodzivirira kupisa. Kunyange zvazvo furo repolyurethane rakapfava uye furo repolyisocyanurate (polyiso) richinyanya kuzivikanwa nekudzivirira kupisa, kugona kwefuro repolyurethane kuchengetedza simba kwakawanda kunokosha. Furo iri rinogona kuderedza zvakanyanya mitengo yesimba nekuwedzera kushanda zvakanaka kwesystem yekudziyisa nekutonhodza, nokudaro richibatsira mukugara kwakanaka uye kushanda munzvimbo dzinogara kwenguva refu.
Mukupedzisa, kushandiswa kwe polyurethane catalysts sengeMXC-TMukugadzirwa kwefuro rakapfava repolyurethane rinovhura mikana yakawanda mumaindasitiri akasiyana-siyana. Hunhu hwechigadzirwa ichi hwakareruka, hunogara kwenguva refu, hunotsigira, uye hune kugadzikana hunoita kuti chive chakakosha mumachira, fenicha, mukati memotokari, nezvimwewo. Kugona kwaro kuita zvinhu zvakasiyana-siyana uye kushanda kwaro kunoita kuti rirambe riri chinhu chakakosha mukutsvaga zvigadzirwa zviri nani uye zvinogara kwenguva refu uye mhinduro.
