Ama-polyurethane foams (SPF) anezimbobo ezifuthwayo asetshenziswa kabanzi ekufakweni kokushisa, ekufakweni komsindo kanye nezinto zokwakha ezilula. Ukukhiqizwa nokusebenza kwe-SPF kungathuthukiswa ngokungeza izinto ezibangela ukucindezeleka ezifana I-MXC-37 (2-[2- (dimethylamino) ethoxy] ethanol, i-DMAEE)Ama-catalyst anjalo asebenza kahle kakhulu ekubhekaneni nezinselele ezifana nephunga lama-amine kanye nokulinganisela ukusabela kwe-reactivity ekwakhiweni okunokuqukethwe kwamanzi amaningi.

1. Indima ye-MXC-37 kuma-SPF

I-MXC-37 ingasetshenziswa njenge-main noma i-co-catalyst ukuthuthukisa inqubo yokukhipha amagwebu nokulungisa:

Ukuncipha kokunambitha kwe-amine:Enye yezinzuzo ezibaluleke kakhulu ze-I-MXC-37yikhono layo lokunciphisa ukunambitheka okuvamile kwe-amine kumkhiqizo oqediwe. I-hydrogen esebenzayo esakhiweni sayo ifakwa ku-polymer matrix, okunciphisa ama-amine ahlala eguquguqukayo.

Ukuhambisana kwamanzi aphezulu:I-MXC-37 ikhombisa umsebenzi omkhulu wokuvuselela amandla ekwakhiweni okusekelwe emanzini, okwenza kube ukukhetha okubanzi kwezinhlelo ze-foam ezinezimbobo ezisebenzisa amanzi njenge-ejenti yokufofa.

Ukusetshenziswa okuguquguqukayo:ingasetshenziswa njenge-catalyst eyinhloko yodwa, noma nge-BDMAEE (bis [2- (dimethylamino) ethyl] ether) kanye namanye ama-tertiary amines njenge-cocatalysts ukunciphisa isidingo se-BDMAEE nokuthuthukisa ukusebenza kahle kwezindleko.

2. Izinzuzo Ekukhiqizweni kwe-SPF

I-MXC-37 ingasetshenziswa njenge-main noma i-co-catalyst ukuthuthukisa inqubo yokukhipha amagwebu nokulungisa:

Ukuncipha kokunambitha kwe-amine:Enye yezinzuzo ezibaluleke kakhulu ze-MXC-37 yikhono layo lokunciphisa ukunambitheka okuvamile kwe-amine kumkhiqizo oqediwe. I-hydrogen esebenzayo esakhiweni sayo ifakwa ku-polymer matrix, okunciphisa ama-amine asele aguquguqukayo.

Ukuhambisana kwamanzi aphezulu:I-MXC-37 ikhombisa umsebenzi omkhulu wokuvuselela amandla ekwakhiweni okusekelwe emanzini, okwenza kube ukukhetha okubanzi kwezinhlelo ze-foam ezinezimbobo ezisebenzisa amanzi njenge-ejenti yokufofa.

Ukusetshenziswa okuguquguqukayo:ingasetshenziswa njenge-catalyst eyinhloko yodwa, noma nge-BDMAEE (bis [2- (dimethylamino) ethyl] ether) kanye namanye ama-tertiary amines njenge-cocatalysts ukunciphisa isidingo se-BDMAEE nokuthuthukisa ukusebenza kahle kwezindleko.

3. Ukusetshenziswa Okubalulekile Kwe-SPF Ezinezimbobo

Ama-SPF anezimbobo aqaliswe yizinhlelo zokusebenza zokuthola ze-MXC-37 emikhakheni eyahlukahlukene:

Ukushisa Okushisayo:Isetshenziswa ekwakheni izindonga, uphahla, kanye namapayipi ezimboni ukuthuthukisa ukusebenza kahle kwamandla.

Ukuvimbela umsindo:Isakhiwo samaseli avulekile sama-SPF anezimbobo simunca amaza omsindo, okwenza afanelekele ukufudumala kwe-acoustic ezindaweni zokuhlala nezentengiselwano.

Izigcwalisi Ezilula:Ama-SPF anezimbobo asetshenziswa ezintweni zokwakha ezilula, okunciphisa isisindo sonke ngaphandle kokwehlisa amandla.

Izinto Zokupakisha:Izakhiwo zazo ezibamba ukushaqeka zizenza zibe zilungele ukupakishwa okuvikelayo.

4. I-MXC-37 njenge-Cocatalyst

Uma isetshenziswa kanye ne-BDMAEE noma ezinye izikhuthazi ze-amine, i-MXC-37 inikeza:

Ukulawulwa Kokusebenza Okuthuthukisiwe:Ilinganisela ukusabela kwe-foam kanye ne-gel, iqinisekisa ikhwalithi ye-foam efanayo.

Isilinganiso Esincishisiwe Se-Catalyst:Kunciphisa isidingo sokugxila okuphezulu kwe-BDMAEE, okuholela ekongeni izindleko kanye nokunciphisa ukukhishwa kwegesi.

Ukusebenza Okungenziwa Ngokwezifiso:Ivumela ukulungiswa kahle kwesistimu ye-catalyst ukuze kuhlangatshezwane nezimo ezithile zokucubungula kanye nezidingo zokusebenza.

Kungani Kufanele Ukhethe i-MXC-37 yama-SPF?

1. Ukunciphisa Iphunga: Kunciphisa iphunga le-amine kumkhiqizo wokugcina, kuthuthukisa ulwazi lomsebenzisi.

2. Ukuguquguquka: Kufanelekela kokubili izinhlelo zefoam zamaseli avulekile kanye namaseli avaliwe.

3. Okunobungani Nemvelo: Kuhambisana nezindinganiso ze-VOC ephansi kanye nezinga lokukhishwa komoya okuphansi.

4. Ukonga Izindleko: Kunciphisa ukuthembela kuma-catalyst abizayo noma anephunga elibi njenge-BDMAEE.

5. Ikhwalithi Yegwebu Ethuthukisiwe: Iqinisekisa ukwakheka kweseli okuhlala njalo, ukuvuleka okuphezulu, kanye nokunamathela okuqinile.

Ngokufaka i-MXC-37 ezinhlelweni ze-polyurethane foam ezifuthwayo ezinezimbobo, abakhiqizi bangakhiqiza ama-foam asezingeni eliphezulu, anobungani nemvelo anephunga eliphansi kanye nokusebenza okuthuthukisiwe, okuhlangabezana nezidingo zezimboni zesimanje zokushisa nokwakha.
