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, anquma 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?
Ifoam ye-polyurethane enamaseli avaliwe iyinto eqinile yokuvikela lapho iningi lamaseli livalelwe futhi ligcwele izinto ezivunguzayo. Uma kuqhathaniswa nefoam enamaseli avulekile, ifoam enamaseli avaliwe ilukhuni, 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 omshini. 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.
