Mhedzisiro yeMXC-T inokonzeresa kusimbaradza kwemvura inobva mukukwanisa kwayo kukurudzira mashandiro eurea pakati pemvura nemaisocyanates, chinhu chakakosha mukugadzirwa kwemafuro epolyurethane. Boka rehydroxyl rinoshanda muMXC-T rinokurudzira kudyidzana kwaro nepolymer matrix, zvichikonzera curve yemhinduro yakagadzikana uye inodzorwa. Curve iyi yakatsetseka yakakosha pakugadzirwa kwemafuro emhando yepamusoro ane kugara kwenguva refu uye hunhu hwekushanda.
MXC-TKushanda kwe catalytic kwakavakirwa pakukwanisa kwayo kukurudzira reaction ye urea pakati pemvura ne isocyanate, iyo inonyanya kukosha mukugadzirwa kwe polyurethane foam. Boka re hydroxyl riri mukati me MXC-T rinoita kuti rishande zvakanaka ne polymer matrix, zvichikonzera kuti reaction curve irambe yakarongeka uye inodzorwa. Iyi curve yakatsetseka yakakosha pakugadzira maumbirwo e foam emhando yepamusoro ane kugara kwenguva refu uye hunhu hwekushanda zvakanaka.
Chimwe chezvinhu zvinoshamisa zveMXC-T ibasa rayo semushonga wepolyurethane foaming catalyst. Inoshandiswa zvakanyanya mumhando dzakasiyana-siyana, kusanganisira kugadzira bhora rakaoma uye zvinhu zvekurongedza zvakapfava uye zvakaoma zvepolyether. Nekuda kwekuchinjika kweMXC-T, iyi catalyst chikamu chakakosha chekugadzirwa kwezvinhu zvekudzivirira furo zvakapfapfaidzwa, zvine simba rakanaka rekuchengetedza uye hunhu hwakanaka hwekupisa. Kana zvichishandiswa pakudzivirira, MXC-T inoita kuti irambe ichipora zvakakwana uye zvakaenzana, zvichibatsira mukugadzikana kwenguva refu kwefuro uye kuramba zvinhu zvakatikomberedza.
Muindasitiri yemotokari, uko zvinhu zvemukati zvakaita semadhibhodhi nemacushion ezvigaro zvinoda nzvimbo dzine hwema hushoma, MXC-T inoshandiswa zvakanyanya nekuda kwehunhu hwayo hushoma uye hunhu hwayo husingafambe. Nekubatsira maitiro ekuita furo akarurama uye akavimbika, MXC-T inobatsira vagadziri kuwana mhedzisiro inovandudza mhando uye nyaradzo yemukati memotokari. Pamusoro pezvo, hunhu hwayo hwe zero hunosangana nekudiwa kuri kukura kwemaitiro ekugadzira asingakuvadzi nharaunda uye ndeimwe yezvinhu zvikuru zvinobatsira nharaunda zvinoshandiswa munyika dzakadai seJapan, Europe neUnited States.
MXC-T inomiririra kuzvipira kuchengetedza nharaunda pasina kukanganisa mashandiro ayo. Yave chinhu chikuru chinobatsira pakuchengetedza nharaunda nekuda kwekukwanisa kwayo kuderedza kusvibiswa kwemhepo uye kutsigira kugadzirwa kwemafuta emhando yepamusoro epolyurethane. Kugamuchirwa kwayo kwakakura mumisika yepasi rose kunoratidza kushanda kwayo uye kushanduka-shanduka mumashandisirwo akasiyana-siyana.
Nezvedu
Isu tiri vapi vakazvipira vezvinokonzeresa polyurethane, yakatarisana nekupa mhinduro itsva uye dzinogara kwenguva refu kuindasitiri yefoam. Zvigadzirwa zvedu zvakagadzirirwa kusangana nezvinodiwa nevagadziri pasi rese, nekuzvipira kwakasimba kune mhando uye mutoro wekuchengetedza nharaunda. 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.
