Foam yePolyurethane imhando yefoam inoshandiswa zvakasiyana-siyana uye inowanzoshandiswa, ine hunyanzvi mumabasa akasiyana-siyana. Inoshandiswa mumidziyo yakawanda yemukati muUnited States nekune dzimwe nyika, kunyanya muindasitiri yefenicha, uko huwandu hwakasiyana uye kuomarara kunogona kuwanikwa zvichiita kuti ive yakakodzera kushandiswa kwakasiyana-siyana, kazhinji inoshandiswa muupholstery, matiresi, macushion uye insulation. Foam yepolyurethane yakavhurika, kunyanya, yakapfava, inochinjika uye yakareruka, zvichiita kuti ive sarudzo yekutanga yezvigadzirwa zvinoda kunyaradzwa uye kugara kwenguva refu. Hunhu hwefoam iyi hunowedzera hunhu hwayo hwekupisa uye ruzha, zvichiita kuti ive yakakodzera kushandiswa kwakasiyana-siyana kubva pakushongedza mukati kusvika kuzvinhu zvinodzivirira.
Zvinokonzera zvakaita seMXC-A33uye MXC-T zvinoita basa rakakosha mukugadzirwa kwefuro repolyurethane rakavhurika. Izvi zvinokonzeresa kuburitsa furo nekukurumidza makemikari ari pakati peisocyanates, senge toluene diisocyanate kana TDI, uye polyols. Basa razvo nderekuona kuti furo rinoumba chimiro charo chemasero akavhurika, zvichikonzera chinhu chinofema uye chinonamira.
MXC-A33 inogona kushandiswa pamabhurumu akapfava, akaomarara uye asina kuomarara. Inogona zvakare kunyungudutsa zvimwe zvinonyungudutsa zvakaita seMEG, DEG, BDO, nezvimwewo, pakushandisa kwakasiyana.
MXC-TInoshandiswa kugadzira furo rinochinjika repolyether, furo rakaumbwa, furo rakati sandara uye furo rakati sandara. Inonyanya kushandiswa mumota.
Foam yepolyurethane yakavhurika inoshandiswa zvakanyanya mumacushion efenicha emukati nekunze, matiresi efoam yekuyeuka, macushion ezvigaro uye kunyangwe kurongedza kwekurapa nekuda kwekugona kwayo kukwana chimiro chemuviri uye kupa nyaradzo. Kupfava kwayo uye kuchinjika kwayo, pamwe chete nehunhu hwakanaka hwekupisa uye kudzikamisa ruzha, zvinoita kuti ive sarudzo yakakurumbira yekudzivirira kupisa muzvivakwa zvinoshandisa simba shoma.
Muchidimbu, kushandiswa kwe polyurethane catalysts dzakadai seMXC-A33 neMXC-T mukugadzira mafoams akavhurika kunovandudza mashandiro efoam, zvichiita kuti chigadzirwa chekupedzisira chikwane nehunhu hunodiwa pakushandiswa kwakasiyana-siyana senge fenicha nezvinhu zvinodzivirira kupisa. Mingxu Chemical Company yave ichigadzira polyurethane catalysts kwemakore anopfuura makumi maviri, tine nzira yakanakisisa yekushanda uye timu yehunyanzvi yekugadzirisa nekugadzirisa zvigadzirwa zve catalyst zvemusika, vatengi vakawanda, tinogamuchira vatengi kuti vauye kuzobvunza.
