Mafuro epolyurethane akasimba anoshandiswa zvakanyanya mumaindasitiri akadai sekuvaka, kuputira, mota, uye kufiriji. Mafuro epolyurethane akasimba ane simba repamusoro remuchina, hunhu hwakanaka hwekudzivirira kupisa, uye anodzivirira zvakatipoteredza, uye anoshanda zvakanaka mumabasa akasiyana-siyana anonetsa. Chimwe chezvinhu zvakakosha mukuvandudza mashandiro emafuro epolyurethane akasimba ndiko kushandiswa kwemakasitoma epolyurethane.
Zvinhu zvinokonzeresa polyurethane, senge MXC-C15, inoita basa rakakosha mukudzora maitiro emakemikari panguva yekugadzira furo, nokudaro ichikanganisa hunhu hwemuviri uye hwemakemikari hwechigadzirwa chefuro chekupedzisira. MXC-C15 (CAS Nhamba 6711-48-4) i-catalyst isingaburitse, ine hwema hushoma, inogadzirisa amine inowedzera kuumbwa uye chimiro chefuro rakasimba repolyurethane nekusimudzira maitiro anodiwa pakati pezvikamu zveisocyanate nepolyol. Ngatinyatsoongororai kuti macatalysts epolyurethane akadai seMXC-C15 anokanganisa sei hunhu hwefuro rakasimba repolyurethane.
Hunhu Hwakagadziridzwa
Foam yakasimba yepolyurethane ine hunhu hwakanaka, uye zvinokonzeresa polyurethane zvinoita basa rakakosha mukuvandudza hunhu uhwu. Zvimwe zvehunhu hukuru hwefoam yakasimba yepolyurethane zvinosanganisira:
Kuwanda uye Kuvimbika kweMagadzirirwo
Kuwanda kwefuro rakasimba repolyurethane kunowanzova pakati pe30-40 kg/m2³, iyo inopa kuenzana kwakanakisa kwesimba nehuremu. Polyurethane catalysts dzakadai seMXC-C15 dzinobatsira kudzora maitiro ekufuridza furo, zvichikonzera chimiro chemasero chakafanana, chakanaka. Chimiro ichi chakakosha pakuona kusimba kwekudzvanya, kugara kwenguva refu uye kusimba kwechimiro chefuro. Nekuda kweizvozvo, furo repolyurethane rakasimba rinogona kushandiswa muzvishandiso zvakaita sekudzivirira zvivakwa uye mapaneru anotakura mutoro pasina kukanganisa mashandiro.
Kudzivirira Kupisa uye Kufambisa Kunopisa Kwakaderera
Chimwe chezvinhu zvinonyanya kukosha zve polyurethane foam yakasimba ndechekuti ine simba shoma rekupisa, iro rinowanzova pakati pe0.018 ne0.024 W/mK. Iyi thermal insulation properties inobatsira kuderedza kushandiswa kwesimba uye inovandudza kushanda zvakanaka kwesimba rezvivakwa nemasystem. Basa re polyurethane catalysts mukudzora reaction rate uye foam structure rakakosha pakuwana thermal conductivity yakaderera inodiwa. Nekukanganisa kuwedzera uye kupora kwezvikamu, catalysts dzakadai seMXC-C15 dzinoita kuti reaction curve iite zvakanaka, zvichibatsira kuti foam iite sero, izvo zvakakosha pakushanda kwayo zvakanaka kwekupisa.
Kudzivirira Hunyoro uye Mvura
Maumbirwo emasero akavharwa efoam yakasimba yepolyurethane inowedzera kuramba kwayo kunyorova uye kupinda kwemvura. Polyurethane catalysts inobatsira kugadzirisa maumbirwo emasero efoam, zvichiita kuti chiyero chepamusoro chemasero akavharwa chiwanikwe. Izvi, zvinopawo kuramba kwakanyanya kwemvura, zvichiita kuti furo racho rikwanise kushandiswa panze apo kusangana nehunyoro kuri dambudziko, senge padenga, kuputira madziro, uye panels dzakachengetwa mufiriji.
Hunhu Hwakawedzerwa hweMakemikoro
Zvinhu zvinokonzeresa polyurethane hazvingokanganisi chete hunhu hwefoam yakasimba yepolyurethane asiwo zvinokanganisa hunhu hwayo hwemakemikari, zvichibatsira kuti igare kwenguva refu uye isakwanise kurwisa zvinhu zvakasiyana-siyana zvakatipoteredza.
Kuramba Kemikari
Mafuro epolyurethane akasimba anodzivirira zvakanyanya makemikari akasiyana-siyana, anosanganisira maasidhi, mabhesi, uye zvinonyungudutsa, zvichiita kuti ave sarudzo yakakurumbira munzvimbo dzakaoma dzemaindasitiri uko furo rinogona kusangana nezvinhu zvinoparadza. Zvinokonzera zvakaita seMXC-C15 zvinoshanda nekukurumidzisa reaction yeurea (isocyanate-water) panguva yekugadzira furo. Izvi zvinobatsira kuvandudza kugadzikana uye kugara kwenguva refu kwefuro, zvichiita kuti rirambe richidzivirira makemikari nekufamba kwenguva.
Kudzivirira Murazvo
Kudzivirira moto chinhu chakakosha pazvinhu zvinoshandiswa mukuvaka, kutakura, uye zvimwe zvinoshandiswa pakuchengetedza. Kunyange zvazvo furo repolyurethane rakasimba richibvira moto, rinogona kugadziriswa kuti rirege kupiswa nekushandisa zvimwe zvinodzivirira moto muchimiro chacho. Zvinhu zvinosimbisa moto zvakaita seMXC-C15 zvinobatsira pakukwira kwakanaka uye kwakadzorwa kwefuro panguva yekugadzira, zvichiita kuti furo rikwanise kushandisa zvinhu izvi zvinobudirira. Izvi zvinoita kuti furo rive rakasimba uye rinogona kusangana nezvinodiwa zvekuchengetedza moto pasina kukanganisa zvimwe zvinhu zvaro.
Kuramba Zvakatipoteredza Uye Kukwegura
Kugara kwenguva refu kwefuro repolyurethane rakasimba kunowedzerwa zvakanyanya nekukwanisa kwaro kutsungirira zvinhu zvakaita sekuchinja-chinja kwekushisa, hunyoro uye kusvibiswa neUV. Polyurethane catalysts inobatsira kugadzirisa maitiro ekupisa, ichiva nechokwadi chekuti furo rinochengetedza simba raro uye kusimba kunyangwe mumamiriro ezvinhu akaoma. Maumbirwo efuro anoramba aripo uye hunhu hwaro hwemakemikari hunogadzikana nekufamba kwenguva, zvichiita kuti rive sarudzo yakapararira yekushandisa kwenguva refu munzvimbo dzinoda simba.
Basa reMXC-C15muSisitimu yeFoam yePolyurethane Yakasimba
MXC-C15 chinhu chinoshanda che amine catalyst chinoita basa guru mukugadzirisa mashandiro emakemikari panguva yekugadzira furo re polyurethane rakagadzika. Inonyanya kubatsira mumasisitimu anoda nzira yakatsetseka uye inodzorwa yekuita. Nekuvandudza kupora kwepamusoro uye kukurudzira kupora kunobudirira mumasisitimu ekuumba anochinjika, MXC-C15 inoita kuti furo rirambe riine hunhu hwaro hwemuviri nemakemikari muhupenyu hwaro hwese. Iyi catalyst inewo mabhenefiti ekusava nemhepo inoburitsa uye kunhuhwirira kushoma, uye inoshandiswa zvakanyanya muindasitiri yekudzivirira zvakatipoteredza.
Mhedziso
Zvishandiso zvepolyurethane zvakakosha pakugadzira hunhu hwemuviri uye hwemakemikari hwefuro rakasimba repolyurethane. Zvishandiso zvakaita seMXC-C15 zvinovandudza huwandu hwefuro, kuputira kupisa, simba rechimiro, uye kuramba makemikari. Mugumisiro wacho inyaya inoshandiswa zvakasiyana-siyana, inogara kwenguva refu inoshanda zvakanaka mumabasa akasiyana-siyana emaindasitiri, ekutengeserana, uye ekugara. Ingave iri kuvandudza kushanda zvakanaka kwesimba, kuwedzera kunonoka kwemoto, kana kupa kuramba kunokonzerwa nezvakatipoteredza, kushandisa zvishandiso zvepolyurethane ndiko kunokosha pakuvhura kugona kwefuro rakasimba repolyurethane.
