Ukufakwa kwe-spray foam kuyisisombululo sokufakwa kwe-insulation esisebenza kahle kakhulu esakhiwe ngezinto ezimbili eziyisisekelo: i-polyurethane ne-isocyanate. Izingxenye ezimbili zigcinwa ngokwehlukana futhi azixutshwa ndawonye kuze kube yisikhathi sokusetshenziswa. Uma sezixutshwe, zithola ukusabela kwamakhemikhali okubangela ukuthi ingxube ikhule kakhulu, igcwalise izikhala nezindawo okunzima ukuzifinyelela. Lokhu kwanda akugcini nje ngokuthuthukisa ukufakwa kwe-insulation, kodwa futhi kunikeza umphumela womoya, othuthukisa ukusebenza kahle kwamandla.
I-Polyurethane iyi-polymer eguquguqukayo eyisisekelo se-spray foam. Inezakhiwo ezinhle kakhulu zokuvimbela ukushisa kanye nekhono lokwenza ama-foam aqinile futhi aguquguqukayo. I-Isocyanate iyikhemikhali esabelayo esebenza ngokubambisana ne-polyurethane ukwakha isakhiwo se-foam. Lezi zinto ezimbili zanda ngokushesha uma zisetshenziswa ukwakha i-foam ebanzi enamathela ebusweni futhi inikeza ukuvimbela ukushisa okuhle kakhulu, ukumelana nomswakama kanye nokuqina.
Izinhlobo Zokushiswa Kwe-Spray Foam
Kunezinhlobo ezimbili eziyinhloko zokuvikela i-spray foam ezisetshenziswa ekwakheni nasekukhiqizeni:
Igwebu Lokufutha Elivulekile: Le foam inobukhulu obuphansi futhi iyisinqumo esithandwayo sokusetshenziswa kwangaphakathi. Inezakhiwo zokuvala umsindo kanye nesivinini sokunwebeka esiphezulu, okwenza iphumelele ekugcwaliseni izikhala ezincane. Ifoam yokufutha yamaseli avulekile ishibhile futhi iguquguquka kunefoam yokufutha yamaseli avaliwe.
Igwebu Lokufutha Elivaliwe: Ifomu yokufutha yamaseli avaliwe inamandla amakhulu okuqina kanye nezakhiwo zokuvikela umswakama futhi ivame ukusetshenziswa ekusetshenzisweni kwangaphandle noma lapho kudingeka khona ukumelana nomswakama ophezulu. Yakha isithiyo esingangeni manzi futhi ifanele ukusetshenziswa ophahleni, ezindlini ezingaphansi komhlaba, nasezindaweni ezivame ukuba nomswakama.
Indima Ka-Ama-Catalyst e-Polyurethane
Ekukhiqizweni kokufakwa kwe-spray foam insulation, ama-polyurethane catalysts adlala indima ebalulekile ekuqhubeni ukusabela kwamakhemikhali phakathi kwe-polyurethane ne-isocyanate. Lawa ma-catalysts alawula isivinini kanye nekhwalithi yenqubo yokugqwala, ukuqinisekisa ukuthi i-foam ikhula kahle, iphola kahle, futhi ifinyelela izakhiwo ezifiselekayo, njengokuqina, ukumelana nokushisa, kanye nokunamathela.
Isikhuthazi sethu se-polyurethaneI-MXC-5iyisikhuthazi se-foam esisekelwe ku-amine esesikhundleni sesithathu esikhuthaza ukusabela kwe-urea (water-isocyanate) ezinhlotsheni ezahlukahlukene zezicelo ze-polyurethane foam eqinile futhi eguquguqukayo. Yisikhuthazi esijwayelekile embonini esisetshenziswa ezinhlelweni ze-polyurethane ezisekelwe ku-MDI, esiza ukuqinisekisa ukusebenza kahle kwe-foam kanye nokungaguquguquki.
Ukusebenzisa i-catalyst ye-polyurethane efanele, njenge-MXC-5, kuqinisekisa ukuthi i-spray foam yakho ifinyelela amandla ayo okuvikela aphelele ngenkathi ithuthukisa ukunwetshwa kwe-foam, izakhiwo zokupholisa, kanye nokuqina kwesakhiwo. Kungakhathaliseki ukuthi ukhiqiza i-spray foam enamaseli avulekile noma enamaseli avaliwe, ukukhetha i-catalyst efanele kubalulekile ekuhlangabezaneni nokusebenza kanye nezindinganiso zemvelo.
Kungani Kufanele Ukhethe I-Catalyst Efanele?
Abakhiqizi be-spray foam kumele bakhethe i-catalyst efanele ukuze bathole ukuvikelwa kwe-foam okuqhubekayo nokusezingeni eliphezulu. I-catalyst eyenziwe kahle ingenza okulandelayo:
- Thuthukisa ukunwebeka kwegwebu kanye nezikhathi zokuphulukisa.
- Thuthukisa ukunamathela ezindaweni ezahlukene.
- Qinisekisa ukuthi ukukhishwa kwegesi kuphansi futhi uhlangabezana nezindinganiso zomthetho.
- Nikeza umswakama ongcono kanye nokumelana nokushisa.
KwaMingxu Chemicals, sinikeza uhla lwezikhuthazi ze-polyurethane ezisebenza kahle kakhulu, njengeI-MXC-5, eyenzelwe izinhlelo zokusebenza ze-foam eziqinile neziguquguqukayo, ikusiza ukuthi uthuthukise izinqubo zakho zokukhiqiza kanye nokusebenza komkhiqizo.
Uma unentshisekelo kukho, sicela usithinte ukuthola ulwazi olwengeziwe ku-info@mingxuchem.com.
