Mumaindasitiri emazuva ano ekudzivirira kupisa nekuvaka, furo repolyurethane rakavharwa rave mhinduro inotungamira nekuda kwekudzivirira kupisa kwakanyanya, hunhu hwaro hwekudzivirira hunyoro, uye simba rechimiro. Pakati pemasisitimu efuro rema cell akavharwa anoshanda zvakanyanya pane ma polyurethane catalysts, ayo anodzora mafambiro ari pakati pema polyols nema isocyanates, zvichiratidza chimiro chefuro, kumhanya kwekuita, uye mashandiro ekupedzisira. Semugadziri wehunyanzvi we polyurethane catalysts, tinopa mhando dzakasiyana dzemhinduro dzakagadzirirwa kushandiswa kwefuro rema cell akavharwa.
Chii Chinonzi Foam yePolyurethane Yemasero Akavharwa?
Foam yepolyurethane ine masero akavharwa chinhu chinodzivirira kupisa uko masero mazhinji akavharirwa uye akazadzwa nezvinhu zvinofefetera. Kana tichienzanisa nefoam yemasero akazaruka, foam yemasero akavharwa yakakora, yakasimba, uye ine mwero wakaderera wekupinza mvura. Inoshandiswa zvakanyanya mu:
Kudzivirira zvivakwa nekuvaka
Kuisa mufiriji uye zvinhu zvinotonhorera
Kudzivirira midziyo yeindasitiri
Kudzivirira mapaipi netangi
Masisitimu espray polyurethane furo (SPF)
Basa reCatalysts mukugadzirwa kweFoam yeClosed-Cell
Polyurethane catalysts zvinhu zvakakosha muma closed-cell foam systems. Zvinokurumidzisa uye zvinoenzanisa gelling reaction (pakati pe isocyanate ne polyol) uye blowing reaction (pakati pe isocyanate nemvura kana blowing agents), zvichikanganisa zvakananga:
Maumbirwo uye kufanana kwesero refuro
Maitiro ekuita uye nguva yekugadzirisa
Kugadzikana uye kunamatira kwehukuru hwedivi
Kukosha kwekudzivirira furo rekupedzisira (R-kukosha)
Kusarudza musanganiswa wakakodzera we catalyst kwakakosha kuti uwane chimiro chekukwira chaunoda, nguva yekupisa, uye simba rekudzvanya - kunyanya kana uchishandisa masisitimu ane HFO-based, water-based, kana mixed blowing agent.
Zvinokurudzirwa zvePolyurethane Catalysts zveFoam yeMaseru Akavharwa
Tinopa mhando dzakasiyana dzema catalysts akagadzirwa neamine nesimbi akagadzirirwa kushandiswa kwefuro re polyurethane rakavharika uye rakaomarara:
MXC-T12 (Dibutyltin Dilaurate): Chinhu chinobatsira zvikuru che organotin chinokurudzira kuita kwe gelling, chinovandudza kuomarara kwefuro uye simba rekupedzisira remakanika. Chakanakira kuputira midziyo yemumba nemidziyo.
MXC-B20 (Chinokonzeresa kubatwa neBismuth): Chinhu chisina chepfu, chinobvisa hutsi hushoma panzvimbo pezvinhu zvinokonzeresa tin catalysts. Chinoshanda pamwe chete neamines kukurudzira kunonoka kwepamberi uye mushonga wakasimba wemashure. Chakanakira furo rinopfapfaidzwa uye masisitimu epaneru anoenderera mberi.
MXC-15 (Potassium Octanoate): Chinhu chinobatsira zvikuru pakugadzira isocyanurate trimerization yePIR systems. Chinovandudza kugadzikana kwezvikamu uye kudzivirira moto mufuro rakavharwa.
MXC-37 (DMAEE): Chinhu chinobatsira kuderedza hwema ...
MXC-TMA: Chinhu chinobatsira kugadzira simbi dzinoita kuti dzikwire uye dzifambe zvakaenzana, chinoshandiswa zvakanyanya mukugadzira simbi dzine simba rakanyanya kufanana nemapuranga efoam akaomarara uye mapaneru anoenderera mberi.
Mashandisirwo eCatalysts Edu muFoam Yemasero Akavharwa
Zvishandiso zvedu zve polyurethane catalysts zvinoshandiswa zvakanyanya muzvirongwa zvinotevera zvefuro remaseru akavharwa:
1. Spray Foam Insulation (SPF): Zvishandiso zvedu zvinobatsira kudzora kumhanya kwekukwira uye kupora kwenzvimbo kuti zviite kuti ishandiswe zvakanaka uye irambe yakasimba.
2. Mapaneru ePIR nePUR: Anoshandiswa mukugadzira mapuranga nguva dzose uye asingachinjiki ekudzivirira kupisa kwechivako.
3. Kuisa mufiriji uye Kuchengeta Zvinhu Zvakatonhora: Zvinhu zvedu zvinobatsira pakuvaka masero akanaka uye kugara zvakanaka kwenguva refu.
4. Kudzivirira Mapaipi neTangi: Kunopa kusimba nekukurumidza uye kugadzikana kwekupisa munzvimbo dzine hunyoro hwakawanda kana tembiricha inochinja-chinja.
5. Masisitimu eFoam eBlock: Akakodzera kuputira nekutakura zvinhu.
Sei Uchifanira Kusarudza Isu?
Semugadziri we polyurethane catalyst ane hunyanzvi, tinopa:
Mafomula ekugadzira catalyst akagadzirwa zvichienderana nefoam system yako uye zvinodiwa pakugadzirisa
Rutsigiro rwehunyanzvi uye gwara rekugadzira kubva kunyanzvi dzemakemikari dzine ruzivo
Kuwanikwa kwezvinhu zvakavimbika zvine mhando dzakafanana uye mitengo inokwikwidzana
Kutevedzera mitemo yepasi rose yezvakatipoteredza
Mhedziso
Zvinhu zvinokonzeresa polyurethanezvakakosha pakubudirira kwekugadzira furo remaseru akavharwa. Kunyangwe uri kugadzira furo respray, mapaneru, kana zvikamu zvefiriji, kusarudza sisitimu ye catalyst yakakodzera kwakakosha kuti uwane zvigadzirwa zvemhando yepamusoro uye zvinoshanda zvakanyanya. Taura nesu nhasi kuti udzidze zvakawanda nezvekuti ma catalyst edu angavandudza sei maforamu ako efuro remaseru akavharwa.
