Mafuro epolyurethane anogona kushandiswa zvakasiyana-siyana uye ave chinhu chakakosha mumaindasitiri akawanda. Mhando dzemafuro epolyurethane dzinonyanya kushandiswa dzinosanganisira mafuro emasero akavharwa uye mafuro emasero akavhurika, ese ari maviri ane hunhu hwakasiyana hwakakodzera kushandiswa kwakasiyana. Kugadzirwa kwemafuro aya kunoenderana zvakanyanya nemacatalysts epolyurethane, ayo anoita basa rakakosha mukudzora maitiro emakemikari anopa mafuro aya hunhu hwawo hwakasiyana.
Muchinyorwa chino, tichaongorora musiyano uripo pakati pemafuro emasero akavharwa nemasero akavhurika, mashandisirwo awo, uye kuti macatalyst epolyurethane anobatsira sei kugadzirwa kwawo.
Foam yeMasero Akavharwa vs. Foam yeMasero Akavhurika: Kuenzanisa Kwakadzama
Foam Yemasero Akavharwa
Furo remasero akavharwa ifuro rakasimba, rakakora rine hunhu hwakanyanya hwekudzivirira uye hunhu hwaro hwakanyanya kupfuura furo rakavhurika. Maburi aro akavharwa, zvichiita kuti mhepo kana hunyoro zvisapfuure nepakati, zvichikonzera kuti rirambe richidzivirirwa nemvura zvakanyanya, zvichiita kuti rive rakakodzera kushandiswa kunoda kuchengetedzwa kwehunyoro.
Kuwanda: Furo rine masero akavharwa rine huwandu hwemakirogiramu maviri kusvika matatu pa cubic foot, izvo zvinoita kuti rive rakaomarara uye rive nesimba rechimiro.
Kudzivirira Kupisa: Nekuda kwechimiro chayo chemasero akaomarara, ine hunhu hwakanaka hwekudzivirira kupisa, ine R-value (kupisa kupisa) inowanzoita 6 kusvika 7 pa inch. Izvi zvinoita kuti ive yakakodzera kudzivirira madziro, matenga, uye nzvimbo dzinochengeterwa zvinhu zvinotonhora.
Kuramba Hunyoro: Furo rine masero akavharwa haripindi mvura, zvichiita kuti rive rakakodzera kusviba nemvura, zvakaita sekushandiswa mugungwa kana pasi pevhu.
Mashandisirwo: Inoshandiswa zvakanyanya mukudzivirira furo rinopfapfaidzwa, mafiriji, kudzivirira mapaipi, uye masisitimu edenga.
Foam Yakavhurika
Furo remasero akavhurika, kune rumwe rutivi, ine chimiro chinochinjika uye chakareruka uko masero akavhurika, zvichibvumira mhepo kuzadza nzvimbo dziri pakati pemasero. Furo iri rakapfava uye harina kukora kupfuura furo remasero akavharwa.
Kuwanda: Foam ine maseru akavhurika inowanzova nehuremu hwe 0.5 lbs/ft3, zvichiita kuti ive yakareruka uye inochinjika.
Kudzivirira Kupisa: Ine R-value yakaderera, inowanzoita 3.5 kusvika 4 pa inch, asi ichiri kupa insulation inoshanda yekupisa. Inowanzoshandiswa mukushandiswa kwemukati umo kusadzivirira hunyoro hakusi chinhu chakakosha.
Kudzivirira ruzha: Nekuda kwechimiro chayo chakavhurika, furo rine maseru akavhurika rine hunhu hwakanaka hwekupinza ruzha, zvichiita kuti rikwanise kudzivirira ruzha mukati memadziro nepadenga.
Kunyudzwa kwehunyoro: Kusiyana nefuro rine masero akavharwa, furo rine masero akazaruka rinogona kunwisa hunyoro, izvo zvinoita kuti risakodzere nzvimbo dzine hunyoro hwakawanda.
Mashandisirwo:Inowanzoshandiswa mukudzivirira ruzha, kudzivirira kupisa kwemukati meimba, uye mukuchengetedza machira emukati meimba.
Basa reZvigadziriso zvePolyurethanemukugadzirwa kweFoam
Zvishandiso zvepolyurethane chinhu chakakosha mukugadzira furo remasero akavharwa nemasero akavhurika. Zvishandiso izvi zvine basa rekudzora mashandiro emakemikari pakati pemapolyol nemaisocyanates panguva yekuumbwa kwefuro. Pasina chishandiso, maitiro aya anononoka uye haashande zvakanaka, zvichikonzera furo remhando isina kunaka. Kusarudzwa kwechishandiso kunokanganisa zvakananga hunhu hwefuro hwakadai sekuwanda, chimiro chemasero, nguva yekumuka, uye kumhanya kwekuporesa.
Heino mashandiro anoita macatalyst epolyurethane uye kuti anokanganisa sei kugadzirwa kwefuro:
1. Kuenzanisa Kupindura Pakati pePolyols neIsocyanates
Mukugadzirwa kwefuro repolyurethane, zvinhu zvinokatyamadza zvinobatsira kudzora maitiro maviri makuru:maitiro e gellinguyekuvhuvhuta kwemhepoKuitwa kwe gelling kunoreva kuumbwa kwechimiro che polymer, ukuwo kufefetera kuchigadzira gasi rinokura furo.
Zvinhu zvinokonzeresa polyurethane zvinogona kupatsanurwa muzvikamu zviviri:zvinokonzeresa amineuyezvinokonzeresa simbi, ese ari maviri ane mabasa akasiyana:
Zvinokonzera Amine: Izvi zvinokonzeresa, zvakaita seMXC-37 (DMAEE)uyeMXC-A1 (BDMAEE), kusimudzirakuvhuvhuta kwemhepo, zvichibatsira kudzora chimiro chemasero efuro. Izvi zvinonyanya kukosha mukugadzirwa kwefuro remasero akavhurika, uko catalyst inoda kugadzira chimiro chinofefetera uye chinochinjika.
Zvinokonzera Simbi: Dibutyltin dilaurate (MXC-T12)semuenzaniso, inonyanya kukurudziramaitiro e gelling, zvichikonzera kuumbwa kwechimiro chakasimba uye chakasimba. Mukugadzirwa kwefuro rine masero akavharwa, zvinhu izvi zvakakosha pakuwana hunhu hwefuro.
2. Kugadzirisa Kuwanda kweFoam uye Simba rayo
Sisitimu ye catalyst inoita basa guru mukutsanangurakuwandauyesimbayefuro. Kune furo rine maseru akavharwa, chinhu chinobatsira kuti furo rive nesimba rinodiwa uye rirambe rakakora kuti rikwanise kumira kumanikidzwa kwemuchina, nepo kune furo rine maseru akazaruka, chinhu chinobatsira kuchengetedza chimiro chakapfava uye chinochinjika. Zvinobatsira zvakaita seMXC-15 (potassium octanoate)zvinonyanya kushanda pakuvandudza huwandu hwefuro uye kuona kuti masero anopararira zvakaenzana, izvo zvakakosha pakudzivirira kupisa kwemhepo kunoshanda zvakanyanya.
3. Kudzora Nguva Yekukwira uye Kukurumidza Kupora
Mukushandiswa kwefuro repurasitiki (SPF), kudzora nguva yekukwira uye kumhanya kwekupora kwakakosha kuti uve nechokwadi chekuti rinoiswa zvakanaka uye chigadzirwa chekupedzisira chinogara kwenguva refu.MXC-T(chinhu chinobatsira kugadzira tin chakafanana neT) kanaMXC-R70(2-(2-dimethylaminoethoxy)ethanol)dzakagadzirirwa kupa nguva yekupora nekukurumidza uye kuita kwakaringana, zvichibvumira kuiswa kwefuro zvakanaka panzvimbo yacho. Kupora nekukurumidza zvinoreva nguva pfupi isina kubatwa uye kugona kuisa zvidimbu zvakawanda nekukurumidza, izvo zvakakosha mukushandiswa kukuru kweSPF.
4. Kuderedza Hutsi Hunobva Mumhepo Uye Kunhuhwirira
Mukugadzirwa kwefuro kwemazuva ano, kufunga nezvezvakatipoteredza kwakakosha, uye kuderedza kusvibiswa kwemhepo nekunhuhwirira kunobva muzvinhu zvinokonzera kusvibiswa kwemhepo kwave chinhu chinonyanya kukosheswa. Zvinhu zvinokonzera kusvibiswa kwemhepo zvishoma, uye zvinoderedza kusvibiswa kwemhepo zvishoma zvakaita seMXC-R40uyeMXC-TMAdzakagadzirirwa kusangana nemitemo yakaoma yezvakatipoteredza ukuwo dzichichengetedza kushanda zvakanaka kwe catalytic. Izvi zvinokonzeresa kupisa mukati meimba, uko kuvapo kwekunhuhwirira kwakasimba kana utsi hunogona kukonzera matambudziko.
Kusarudza Polyurethane Catalyst Yakakodzera Yekushandisa Foam Yako
Kusarudza chinhu chakakodzera chepolyurethane catalyst kwakakosha kuti furo rive nehunhu hwaunoda. Zvinhu zvekufunga nezvazvo zvinosanganisira:
Rudzi rwefuro: Furo rine masero akavharwa kana kuti akavhurika.
Kushandiswa: Kudzivirira kupisa, kudzivirira ruzha, denga, kana kuturikira.
Kufunga nezvezvakatipoteredza: Kubuda kweVOC kwakaderera, kunhuhwirira kwakaderera, uye kutevedzera mitemo yezvakatipoteredza.
Zvinodiwa pakurapa: Nguva dzinokurumidza kana kuti dzinononoka kupora zvichibva pakugadzirwa.
At Nhoroondo ye Mingxu Chemicals, isu tine hunyanzvi mukupa macatalyst epolyurethane anoshanda zvakanaka akagadzirirwa mashandisirwo enyu chaiwo efuro. Kunyangwe muri kugadzira spray foam insulation yezvivakwa kana zvinhu zvinodzivirira ruzha zvemukati, pane zvakawanda zvemacatalyst edu—akadai seMXC-T, MXC-37uyeMXC-R40—inovimbisa kuti unowana furo remhando yepamusoro nekushanda kwakanakisa.
Mhedziso
Kunzwisisa musiyano uripo pakati pemafuro emasero akavharwa nemasero akavhurika uye basa remafuro epolyurethane mukugadzirwa kwawo kwakakosha kune vagadziri vari kutsvaga kugadzirisa zvigadzirwa zvavo zvefuro. Mafuro epolyurethane haangogumiri pakuchinja kwemakemikari anoumba furo asi anoonawo hunhu hwakakosha hwakadai sesimba, huwandu, uye kumhanya kwekupisa. Nekusarudza mafuro akakodzera, vagadziri vanogona kugadzira mafuro anoshanda zvakanyanya anosangana nezvinodiwa zvemashandisirwo akasiyana-siyana, kubva pakudzivirira kupisa kusvika pakudzivirira ruzha.
Kana uchitsvaga mhinduro dzemhando yepamusoro mukugadzira furo repolyurethane,Nhoroondo ye Mingxu Chemicalsaripo kuti akubatsire. Taura nesu nhasi kuti udzidze zvakawanda nezvemhando dzakasiyana dzema "polyurethane catalysts" edu anoshanda zvakanyanya akagadzirirwa kuvandudza maitiro ako ekugadzira furo.
