Indima Yama-Gel Catalysts ku-Polyurethane: Ukuqonda i-MXC-T12 (DBTDL) ku-Gelling Reaction

Iyini i-Gel Catalyst?

Ii-gel catalystkumakhemikhali e-polyurethane kuyinto esheshisa ukusabela phakathi kwe-i-isocyanatekanyei-polyol, kanye nezibopho ze-polyurethane ezakhiwe zinikeza isakhiwo sokugcina sezinto. Lokhu kusabela kubalulekile ekukhiqizweni kwe-polyurethane ngoba kunqumaizakhiwo zemishinifuthiukuzinzayegwebu noma i-coating ephumayo. I-catalyst yejeli ikhuthaza isigaba "sokuxhumanisa" noma "sokuqinisa", esivame ukubizwa ngokuthi ukusabela kwe-gelling, kunokuba i-catalyst evunguzayo ikhuthaze ukusabela phakathi kwe-isocyanate namanzi, ikhiphe i-carbon dioxide, kanye nokwanda kwegwebu.

Indlela Yokusabela Ku-Gel Catalyst

  1. Ukusebenza kwe-Polyol ne-Isocyanate:Ama-catalyst e-gel, njengei-dibutyltin dilaurate (I-DBTDL)ku-MXC-T12, sebenzisa amaqembu e-hydroxyl kumaqembu e-polyol kanye ne-isocyanate. Lokhu kunciphisa isithiyo samandla sokuhlasela kwe-nucleophilic kweqembu le-hydroxyl le-polyol ku-carbon ye-isocyanate.
  2. Ukwakheka kokuxhumana kwe-Urethane:I-catalyst yenza kube lula ukwakheka kwezibopho ze-urethane ngokusheshisa i-reaction kinetics. Lokhu kuholela ekuxhumeni kwe-cross-link yamaketanga e-polymer, okwandisa i-viscosity futhi kwenze izinto zibe lukhuni.
  3. I-Catalysis Ekhethiwe: I-DBTDL (MXC-T12)ukhetha ngokukhethekileukusabela kwejelifuthi kuqinisekisa ukufana kokwelapha. Akukhuthazi kakhulu ukusabela okubi njengokuhluza ama-isocyanates, okuqinisekisa izakhiwo zomkhiqizo ofiselekayo.

Ukusetshenziswa kwe-MXC-T12 (DBTDL) njenge-Gel Catalyst

I-MXC-T12 isetshenziswa kabanzi ezinhlelweni ze-polyurethane lapho ukunemba nokulawula ukusabela kwejeli kubalulekile. Nazi izindima zayo ezimweni ezahlukene zokusetshenziswa:

1.Igwebu Lokufutha:

I-MXC-T12 iqinisekisa ukuphola okusheshayo kanye nokuxhumanisa okufanayo kuma-spray foam avaliwe noma avulekile.

Ilinganisela ukusabela phakathi kokwanda (ukuvuthela) kanye nokuqina (ukugaya), iqinisekisa ukuthi i-foam ifinyelela izakhiwo ezifiselekayo.

I-Metal Catalyst

2.Izimbozo kanye Nezinamathiselo:

Ezimbozweni, i-MXC-T12 ikhuthaza ukuqiniswa okulinganayo, okuholela endaweni ebushelelezi nehlala isikhathi eside.

Kuma-glue, kuqinisekisa izibopho eziqinile ngokusheshisa ukusabela kwe-gelling ukuze kube nokuhlangana okuphezulu.

3.Amagwebu Aqinile Naguquguqukayo:

Kuma-foam aqinile, i-MXC-T12 isiza ekufinyeleleni ukuzinza okuphezulu kanye namandla okucindezela.

Kuma-foam aguquguqukayo, kuqinisekisa ukuqina nokuqina okuqhubekayo ngokulawula ukwakheka kwe-urethane.

Ama-Reaction Dynamics ane-MXC-T12

  1. Isilinganiso Esiphansi, Umsebenzi Ophezulu:I-MXC-T12 iyasebenza kahle uma amazinga aphansi egazi, inikeza ukulawula okuhle kakhulu iphrofayili yokusabela.
  2. Ukwelapha Kwangemuva:I-MXC-T12 iqinisekisa ukuqina okuphelele ngisho nangemva kwesigaba sokuqala sokusabela, okufaka isandla ekuzinzeni okungcono kokushisa kanye namandla omshini.
  3. Ukuzinza kwe-Hydrolytic:Igcina ukusebenza kahle ezindaweni ezinomswakama, okwenza ifaneleke ekwakhiweni okuvezwe emanzini noma emswakama.

Ngokufigqiwe,I-MXC-T12 (DBTDL)Idlala indima ebalulekile njengesikhuthazi sejeli ezinhlelweni ze-polyurethane ngokwenza kube lula ukuxhumanisa okunembile. Ukusebenza kahle kwayo nokukhetha kwayo kuyenza ibe ukukhetha okubanzi kwezicelo ezidinga ukuqina, ukuzinza, kanye nokusebenza okuqhubekayo, njenge-spray foam, i-coating, kanye ne-glue.
