Isingeniso
Ezimbonini zanamuhla zokushisa nokwakha, i-polyurethane foam yamaseli avaliwe isibe yisisombululo esihamba phambili ngenxa yokumelana kwayo nokushisa okuphezulu, izakhiwo zokuvimbela umswakama, kanye namandla esakhiwo. Enhliziyweni yezinhlelo ze-polyurethane foam zamaseli avaliwe ezisebenza kahle kakhulu kukhona ama-polyurethane catalysts, alawula ukusabela phakathi kwama-polyol nama-isocyanates, okunquma isakhiwo se-foam, isivinini sokusabela, kanye nokusebenza kokugcina. Njengomkhiqizi ochwepheshe wama-polyurethane catalysts, sinikeza uhla olubanzi lwezixazululo ezenzelwe ukusetshenziswa kwe-polyurethane foam yamaseli avaliwe.
Iyini i-Foam ye-Polyurethane enamaseli avaliwe?
I-polyurethane foam enamaseli avaliwe iyinto eqinile yokuvikela lapho iningi lamaseli livalelwe futhi ligcwele izinto ezivunguzayo. Uma kuqhathaniswa ne-foam enamaseli avulekile, i-foam enamaseli avaliwe iqinile, inamandla, futhi inesilinganiso esiphansi sokumuncwa kwamanzi. Isetshenziswa kabanzi ku:
Ukushisa kwesakhiwo nokwakhiwa
Ukuqandisa kanye nokufakwa kwemishini ebandayo
Ukushisa imishini yezimboni
Ukufakwa kwepayipi kanye nokufakwa kwethangi
Izinhlelo ze-spray polyurethane foam (SPF)
Indima Yama-Catalyst Ekukhiqizweni Kwe-Foam Yamaseli Avaliwe
Ama-catalyst e-polyurethane ayizinto ezibalulekile ezinhlelweni ze-foam ezivaliwe. Asheshisa futhi alinganisele ukusabela kwe-gelling (phakathi kwe-isocyanate ne-polyol) kanye nokusabela kokuvunguza (phakathi kwe-isocyanate namanzi noma ama-ejenti okuvunguza), okuthinta ngqo:
Isakhiwo seseli le-foam kanye nokufana
Iphrofayili yokusabela kanye nesikhathi sokucubungula
Ukuqina nokuqina kobukhulu
Inani lokugcina lokufakwa kwe-foam (inani le-R)
Ukukhetha inhlanganisela efanele ye-catalyst kubalulekile ukuze kufezwe iphrofayili yokukhuphuka oyifunayo, isikhathi sokupholisa, kanye namandla okucindezela—ikakhulukazi uma kusetshenziswa izinhlelo ze-HFO-based, water-based, noma mixed blowing agent.
Ama-Catalyst e-Polyurethane Anconyiwe e-Closed-Cell Foam
Sihlinzeka ngezinhlobonhlobo zama-catalyst asekelwe kuma-amine kanye nensimbi aklanyelwe ngqo ukusetshenziswa kwe-polyurethane foam eqinile, evaliwe ngamaseli:
I-MXC-T12 (i-Dibutyltin Dilaurate): I-organotin catalyst esebenza kahle kakhulu ekhuthaza ukusabela kwe-gelling, ithuthukisa ubulukhuni be-foam kanye namandla okugcina okusebenza. Ilungele ukufakwa kwe-board stock kanye ne-appliance insulation.
I-MXC-B20 (I-Catalyst esekelwe ku-Bismuth): Indlela engeyona enobuthi, ekhipha ukungcola okuncane esikhundleni se-tin catalysts. Isebenza njenge-co-catalyst enama-amine ukukhuthaza ukubambezeleka okulinganayo kwe-front-end kanye nokwelashwa okuqinile kwe-back-end. Ilungele kakhulu izinhlelo ze-spray foam kanye ne-continuous panel.
I-MXC-15 (i-Potassium Octanoate): Isikhuthazi sokunciphisa i-isocyanurate esisebenza kakhulu sezinhlelo ze-PIR. Sithuthukisa ukuzinza kobukhulu kanye nokumelana nomlilo ku-foam eqinile yamaseli avaliwe.
I-MXC-37 (i-DMAEE): Isikhuthazi se-amine esinephunga eliphansi esisetshenziselwa ukuthuthukisa ukusabela kanye nokunciphisa ukukhishwa kwegesi. Ifanelekela amagwebu e-cold-chain kanye nama-packaging lapho ukulawula iphunga kubalulekile khona.
I-MXC-TMA: I-catalyst yokulungisa i-trimer evumela ukuphakama nokugeleza okufanayo, esetshenziswa kabanzi ekwakhiweni kwe-high-viscosity njengamabhodi e-foam aqinile namaphaneli aqhubekayo.
Ukusetshenziswa kwama-Catalyst ethu ku-Closed-Cell Foam
Ama-catalyst ethu e-polyurethane asetshenziswa kabanzi ezinhlelweni ze-foam zamaseli avaliwe ezilandelayo:
1. Ukuvikela I-Spray Foam (SPF): Ama-catalyst ethu asiza ukulawula isivinini sokukhuphuka kanye nokwelashwa kwendawo ukuze kufezwe ukusetshenziswa okubushelelezi kanye nokunamathela okuqinile kwe-substrate.
2. Amaphaneli e-PIR ne-PUR: Asetshenziswa ekukhiqizweni kwamabhodi okuqhubekayo nokungapheli kokuvikela isakhiwo.
3. Ukuqandisa kanye Nokugcina Izinto Ezibandayo: Ama-catalyst ethu anegalelo ekwakheni amaseli amahle kanye nokuzinza kwesikhathi eside.
4. Ukufakwa Kwepayipi Nethangi: Kuhlinzeka ngokuqina okusheshayo kanye nokuqina kokushisa ezindaweni ezinomswakama ophezulu noma ezishintshashintshayo.
5. Izinhlelo Ze-Block Foam: Zifanelekela ukupakisha nokuvikela ukuthuthwa.
Kungani Kufanele Ukhethe Thina?
Njengomkhiqizi we-polyurethane catalyst ochwepheshe, sinikeza:
Ukwakheka kwe-catalyst ngokwezifiso okusekelwe ohlelweni lwakho lwe-foam nezidingo zokucubungula
Ukusekelwa kobuchwepheshe kanye nesiqondiso sokwakheka okuvela kosokhemisi abanolwazi
Ukunikezwa komkhiqizo okuthembekile okunekhwalithi ehambisanayo kanye namanani ancintisanayo
Ukuhambisana nezindinganiso zemvelo zomhlaba wonke
Isiphetho
Ama-catalyst e-polyurethanezibalulekile ekukhiqizweni okuphumelelayo kwe-foam yamaseli avaliwe. Kungakhathaliseki ukuthi ukhiqiza i-spray foam, amaphaneli, noma izingxenye zesiqandisi, ukukhetha uhlelo lwe-catalyst olufanele kuyisihluthulelo sokufeza imikhiqizo esezingeni eliphezulu nesebenza kahle. Xhumana nathi namuhla ukuze ufunde kabanzi mayelana nokuthi ama-catalyst ethu angathuthukisa kanjani ukwakheka kwe-foam yamaseli avaliwe.
