Mafoam a polyurethane opangidwa ndi porous spray-coated spray (SPF) amagwiritsidwa ntchito kwambiri poteteza kutentha, kuteteza phokoso komanso zipangizo zomangira zopepuka. Kupanga ndi kugwira ntchito kwa SPF kumatha kukonzedwa bwino powonjezera zinthu zoyambitsa kutentha monga MXC-37 (2-[2- (dimethylamino) ethoxy] ethanol, DMAEE)Ma catalyst otere ndi othandiza kwambiri pothana ndi mavuto monga fungo la amine komanso poyesa kuyanjana kwa mankhwala omwe ali ndi madzi ambiri.

1. Udindo wa MXC-37 mu SPFs

MXC-37 ingagwiritsidwe ntchito ngati chinthu chachikulu kapena chothandizira kuwonjezera njira yopangira thovu ndi kuchiritsa:

Kuchepa kwa kukoma kwa amine:Chimodzi mwa zabwino kwambiri zaMXC-37ndi kuthekera kwake kuchepetsa kukoma kwa amine komwe kumachitika mu chinthu chomalizidwa. Hydrogen yogwira ntchito m'mapangidwe ake imaphatikizidwa mu polymer matrix, zomwe zimachepetsa ma residual volatile amines.

Kugwirizana kwambiri ndi madzi:MXC-37 imagwira ntchito kwambiri poyambitsa zinthu zochokera m'madzi, zomwe zimapangitsa kuti ikhale njira yabwino kwambiri yopangira thovu lokhala ndi mabowo lomwe limagwiritsa ntchito madzi ngati chothandizira kupeta.

Kugwiritsa ntchito mosavuta:Itha kugwiritsidwa ntchito ngati chothandizira chachikulu chokha, kapena ndi BDMAEE (bis [2- (dimethylamino) ethyl] ether) ndi ma tertiary amine ena ngati ma cocatalysts kuti achepetse kufunikira kwa BDMAEE ndikuwonjezera kugwiritsa ntchito bwino ndalama.

2. Ubwino wa Kupanga kwa SPF

MXC-37 ingagwiritsidwe ntchito ngati chinthu chachikulu kapena chothandizira kuwonjezera njira yopangira thovu ndi kuchiritsa:

Kuchepa kwa kukoma kwa amine:Chimodzi mwa ubwino waukulu wa MXC-37 ndi kuthekera kwake kuchepetsa kukoma kwa amine komwe kumachitika mu chinthu chomalizidwa. Hydrogen yogwira ntchito mu kapangidwe kake imaphatikizidwa mu polymer matrix, zomwe zimachepetsa ma residual volatile amines.

Kugwirizana kwambiri ndi madzi:MXC-37 imagwira ntchito kwambiri poyambitsa zinthu zochokera m'madzi, zomwe zimapangitsa kuti ikhale njira yabwino kwambiri yopangira thovu lokhala ndi mabowo lomwe limagwiritsa ntchito madzi ngati chothandizira kupeta.

Kugwiritsa ntchito mosavuta:Itha kugwiritsidwa ntchito ngati chothandizira chachikulu chokha, kapena ndi BDMAEE (bis [2- (dimethylamino) ethyl] ether) ndi ma tertiary amine ena ngati ma cocatalysts kuti achepetse kufunikira kwa BDMAEE ndikuwonjezera kugwiritsa ntchito bwino ndalama.

3. Kugwiritsa Ntchito Kofunika Kwambiri kwa Ma SPF Okhala ndi Mitsempha

Ma SPF okhala ndi mabowo omwe amathandizidwa ndi MXC-37 kupeza ntchito m'magawo osiyanasiyana:

Kuteteza kutentha:Amagwiritsidwa ntchito pomanga makoma, madenga, ndi mapaipi a mafakitale kuti awonjezere kugwiritsa ntchito mphamvu moyenera.

Kuletsa phokoso:Kapangidwe ka ma SPF okhala ndi mapokoso otseguka kamayamwa mafunde a phokoso, zomwe zimapangitsa kuti akhale oyenera kutetezedwa ndi mawu m'nyumba ndi m'malo amalonda.

Zodzaza Zopepuka:Ma SPF okhala ndi mabowo amagwiritsidwa ntchito popanga zinthu zopepuka, zomwe zimachepetsa kulemera konse popanda kuwononga mphamvu.

Zipangizo Zogulira:Kapangidwe kawo koteteza ku kugwedezeka kamapangitsa kuti zikhale zabwino kwambiri popangira zinthu zoteteza.

4. MXC-37 ngati Cocatalyst

Ikagwiritsidwa ntchito pamodzi ndi BDMAEE kapena ma amine catalysts ena, MXC-37 imapereka:

Kuwongolera Kwambiri kwa Reactivity:Zimayendetsa bwino momwe thovu limagwirira ntchito komanso momwe gel imagwirira ntchito, zomwe zimapangitsa kuti thovu likhale labwino mofanana.

Mlingo Wochepetsedwa wa Catalyst:Kumachepetsa kufunika kwa kuchuluka kwa BDMAEE, zomwe zimapangitsa kuti ndalama zisamawonongeke komanso kuchepetsa mpweya woipa.

Magwiridwe Osinthika:Imalola kukonza bwino makina othandizira kuti agwirizane ndi momwe zinthu zimagwirira ntchito komanso zofunikira pakugwira ntchito.

N’chifukwa Chiyani Muyenera Kusankha MXC-37 ya SPF?

1. Kuchepetsa Fungo: Kumachepetsa fungo la amine mu chinthu chomaliza, zomwe zimapangitsa kuti ogwiritsa ntchito azisangalala.

2. Kusinthasintha: Koyenera makina a thovu a maselo otseguka komanso otsekedwa.

3. Yogwirizana ndi chilengedwe: Imagwirizana ndi miyezo ya VOC yochepa komanso yotulutsa mpweya wochepa.

4. Kugwiritsa Ntchito Ndalama Moyenera: Kumachepetsa kudalira zinthu zodula kapena zonunkha monga BDMAEE.

5. Ubwino wa Thovu: Zimathandiza kuti maselo azikhala bwino, azikhala ndi ma pores ambiri, komanso kuti azigwirana bwino.

Mwa kuphatikiza MXC-37 mu makina opangira thovu la polyurethane opopera, opanga amatha kupanga thovu labwino kwambiri, lopanda kuwononga chilengedwe lomwe lili ndi fungo lochepa komanso magwiridwe antchito abwino, kukwaniritsa zofunikira za makampani amakono oteteza kutentha ndi zomangamanga.
