Ubuchwepheshe bokufudumeza i-polyurethane spray foam kanye nokusetshenziswa okusha kwe-MXC-TMA catalyst

Isimo samanje sobuchwepheshe bokufudumeza i-spray foam

Izinto zokuvikela i-polyurethane spray foam sezibe ubuchwepheshe obuyinhloko bemiklamo yesimanje yokonga amandla yokwakha. Ngokusebenza kwayo okuhle kakhulu kokuvikela ukushisa kanye nezici zokwakha ezingenamthungo, ithatha indawo ebalulekile emakethe yomhlaba wonke yokuvikela izakhiwo. Lobu buchwepheshe bokwakha endaweni bufutha ingxube ye-isocyanate ne-polyol ngqo ebusweni be-substrate, futhi busabela ngokushesha ngaphansi kwesenzo se-catalyst ukwakha isakhiwo se-foam esivaliwe noma esivulekile ukuze kufezwe umphumela omuhle kakhulu wokuvikela.
Ifomu yokufutha evaliwe isibe yisisombululo esithandwayo sokuvikela izindonga zangaphandle zesakhiwo, ophahleni kanye nendawo yokugcina ebandayo ngenxa yokusebenza kwayo okuhle kakhulu kokuvikela ukushisa (ukuqhuba ukushisa okungu-0.020-0.028W/(m·K)) kanye nezici zokuqinisa isakhiwo. Isihluthulelo sokufeza lokhu kusebenza okuhle kakhulu sisekulawulweni okunembile kwesistimu ye-catalyst yokusabela kwe-trimerization kwe-polyisocyanurate.

Ukuthuthukiswa kobuchwephesheI-MXC-TMAi-catalyst

I-MXC-TMA catalyst iyisizukulwane esisha se-trimerization catalyst esakhelwe ngqo i-spray foam. Ifomula yayo entsha ixazulula izinkinga eziningi zobuchwepheshe zama-catalyst asekelwe ku-potassium ngesikhathi sokwakhiwa. Lo mkhiqizo woketshezi olungenambala kuya kophuzi okhanyayo ufinyelela ukulawula okunembile kwe-polyurethane reaction kinetics ngokwakhiwa kwawo kwamakhemikhali okuhlukile.
Ngokuphathelene nokulawula ukusabela, i-MXC-TMA inikeza ijika elikhuphukayo elifanayo nelilawulekayo, linciphisa ngempumelelo into yokuwa ngesikhathi sokwakhiwa kokufutha. Izingxenye zayo ezisebenzayo ezihlukile zilinganisela ukusabela kwe-foam kanye ne-gelling, zigwema ukwenzeka kweziphambeko zobuso, ngenkathi zithuthukisa ijubane lokupholisa futhi zifinyeza kakhulu isikhathi sokwakhiwa.
Ukugeleza okuthuthukisiwe kungenye inzuzo enkulu yobuchwepheshe ye-MXC-TMA. Lo mkhiqizo ungathuthukisa kakhulu izici zokugeleza kwamafomula okuqukethwe okuqinile futhi ufeze ukusatshalaliswa kwe-foam okufanayo, okufanelekela kakhulu ukwakhiwa kokufutha ezindaweni eziyinkimbinkimbi zejometri. Uma kuqhathaniswa nama-catalyst asekelwe ku-potassium yendabuko, i-MXC-TMA isengakwazi ukugcina umsebenzi omuhle wokusabela ezindaweni eziphansi zokushisa, yandisa kakhulu ububanzi bokusetshenziswa kwezinga lokushisa lokwakha.

Izimiso zobuchwepheshe kanye nezinzuzo zokusebenza

I-MXC-TMAikhuthaza ukusabela kwe-trimerization kwama-isocyanates ukwakha isakhiwo sendandatho ye-isocyanurate esizinzile. Lesi sakhiwo samakhemikhali esikhethekile sinikeza izinto ze-foam izinzuzo ezintathu eziyinhloko: ukuzinza kokushisa okuthuthukisiwe kakhulu, izinga lokushisa lokubola lingakhushulwa ngo-30-50℃; ukumelana okuhle kakhulu nomlilo, inkomba ye-oxygen ingafinyelela ku-26-28; ukuzinza okuhle kakhulu kobukhulu, izinga lokushintsha kwevolumu elilawulwa ngaphakathi kwe-1%.
Ezisetshenzisweni ezisebenzayo, sincoma ukusetshenziswa kwe-MXC-TMA kuhlanganiswe nama-catalyst e-amine, kanti isilinganiso silawulwa ku-30-50% we-catalyst iyonke. Umkhiqizo unezinga lokushisa elibanzi lokusebenza (15-35℃), uyahambisana nezinhlobo ezahlukene zama-ejenti e-foam njenge-HFC-245fa kanye ne-HFO-1234ze, futhi ungasetshenziswa kanye nama-polyol amaningi e-polyether/polyester kanye nama-flame retardants amaningi.

Ukusekelwa kobuchwepheshe bochwepheshe kanye nesiqinisekiso sesevisi

Sinikeza ukwesekwa okuphelele kobuchwepheshe kwabakhiqizi be-spray foam yomhlaba wonke kanye nezinkampani zokwakha, okuhlanganisa nezinsizakalo zokuhlola zelebhu, isiqondiso sokwenza ngcono imigqa yokukhiqiza kanye nezixazululo zokuthuthukiswa ezenziwe ngokwezifiso. Ithimba lobuchwepheshe lochwepheshe linganikeza izixazululo zesistimu yokuthuthukisa ngokwezifiso ngokusekelwe ezimweni zemishini ethile yekhasimende kanye nezinqubo.
Ngokuphathelene nohlelo lokuqinisekisa ikhwalithi, sisebenzisa ngokuqinile amazinga okukhiqiza aqinisekisiwe yi-ISO 9001 ukuqinisekisa ukuthi ukuzinza kweqembu lomkhiqizo kudlula u-99%. Inethiwekhi yokuhlinzeka ephelele yomhlaba wonke ingahlangabezana nezidingo zamakhasimende eziphuthumayo zoku-oda futhi iqinisekise inqubekela phambili yokwakhiwa kwephrojekthi.
