Ubuchwepheshe besimanje bephaneli yesangweji kanye nezinto eziyinhloko ze-polyurethane
Njengokusungula izinto ezintsha embonini yokwakha, amaphaneli esandwich e-polyurethane abe yinto ethandwayo yezitshalo zezimboni, indawo yokugcina izinto ebandayo, ama-workshop ahlanzekile kanye nezinye izakhiwo. Lokhu okuhlanganisiwe okuqukethe izendlalelo ezimbili zamaphaneli ensimbi kanye ne-polyurethane foam core ephakathi kuncike kakhulu ohlelweni lobuchwepheshe lwe-polyurethane catalyst ngenxa yokusebenza kwalo okuhle kakhulu. Ama-catalyst ethu ochungechunge lwe-MXC alungiselelwe ngokukhethekile ukukhiqizwa kwamaphaneli esandwich, okungathuthukisa kakhulu ikhwalithi yomkhiqizo kanye nokusebenza kahle kokukhiqiza.
Uhlelo lwe-Catalyst lwamaphaneli e-sandwich
Izinzuzo eziyingqayizivele zeI-MXC-37 (i-DMAEE)i-catalyst
I-MXC-37 (2-(2-(dimethylamino)ethoxy)ethanol, i-CAS 1704-62-7) iyisikhuthazi se-amine esiguqulayo esiletha impumelelo eningi ekukhiqizweni kwamaphaneli esandwich:
- Izici ezingenayo iphunga elibi nezingakhiphi ukungcola: ukuxazulula inkinga yephunga lama-catalyst endabuko e-amine nokuthuthukisa indawo yokukhiqiza
- Umsebenzi wokwenza igwebu kakhulu: ifaneleka kakhulu ekwakhiweni kwamanzi amaningi ukuqinisekisa ukwanda okugcwele kwegwebu
- Imodi yokufaka kabili: ingasetshenziswa yodwa njengesikhuthazi esiyinhloko noma ihlanganiswe ne-BDMAEE
- Ukuhambisana okubanzi: kufaneleka ezinhlelweni ezahlukene ze-polyester ne-polyether polyol
Emgqeni wokukhiqiza oqhubekayo wamaphaneli esandwich, i-MXC-37 inganikeza ijika lokusabela elizinzile ukuqinisekisa ukufana kanye nokuvumelana kwezinto eziyinhloko ye-foam, okubalulekile ukuqinisekisa ukuthi amaphaneli esandwich ayisicaba futhi anobukhulu obufanayo.
Intuthuko kwezobuchwephesheI-MXC-15(isixazululo se-potassium octanoate)
I-MXC-15 (CAS 3164-85-0), njenge-catalyst ye-isocyanurate ephumelelayo, inikeza ukwesekwa okubalulekile ekukhiqizweni kwamaphaneli e-sandwich e-PIR:
- Izinga lokuguqulwa eliphezulu kakhulu: likhuthaza ukwenziwa kwe-isocyanate trimerization futhi lithuthukisa ukuzinza kokushisa kwe-foam
- Isebenza kufomula ye-viscosity ephezulu: yenza ngcono ukugeleza kanye nokufana kokusabela kwezinhlelo zokuqukethwe okuqinile okuphezulu
- Eyongayo futhi esebenza kahle: inani eliphansi lokwengeza lingafeza umphumela omuhle kakhulu wokuvuselela amandla
- Uhlelo lwe-PIR oluhambisanayo lochwepheshe: oluklanyelwe ngokukhethekile amaphaneli esandwich e-polyisocyanurate
I-MXC-15 ingathuthukisa kakhulu ukumelana nomlilo kanye nokuzinza kobukhulu bamaphaneli esandwich, ukuze akwazi ukugcina izakhiwo ezinhle kakhulu zemishini ezindaweni ezinokushisa okuphezulu.
Indima ebalulekileama-catalystekukhiqizweni kwamaphaneli esandwich
Enqubweni yokukhiqiza amaphaneli esandwich e-polyurethane, uhlelo lwe-catalyst luthinta ngqo izinkomba ezilandelayo eziyinhloko:
1. Ukugeleza kwegwebu: qinisekisa ukuthi izinto zokusetshenziswa zigcwalisa ngokuphelele umgodi ophakathi kwamaphaneli ukuze kugwenywe ukushoda kwezinto
2. Isivinini sokwelapha: fanisa izidingo zesivinini zomugqa wokukhiqiza oqhubekayo ukuze kwandiswe umthamo wokukhiqiza
3. Isakhiwo seseli: sithinta ukuqhutshwa kokushisa kanye namandla okusebenza kwephaneli yesangweji
4. Ukusebenza kokunamathela: kunquma amandla okubopha isikhombimsebenzisi phakathi kwezinto eziyinhloko nephaneli
5. Ukuqina kobukhulu: kuvimbela ukuguqulwa kwephaneli okubangelwa ukuncishiswa kwefoam
Ithimba lethu lobuchwepheshe linganikeza ikhambi elingcono kakhulu le-catalyst lemigqa ehlukene yokukhiqiza kanye nezidingo zomkhiqizo ngokulawula ngokunembile isilinganiso se-MXC-37 kanye ne-MXC-15, okusiza amakhasimende ukufeza:
- Khulisa isivinini somugqa wokukhiqiza ngo-20-30%
- Khulisa izinga lokufaneleka komkhiqizo libe ngaphezu kuka-98%
- Nciphisa ukusetshenziswa kwamandla ngo-15-20%
- Ukonga izindleko okubanzi konyaka wonke
Usekelo lobuchwepheshe kanye nezinsizakalo
Sinikeza ukwesekwa kobuchwepheshe okuphelele kwabakhiqizi bamaphaneli esandwich:
- Insizakalo yokwenza ngcono ifomula: lungisa uhlelo lwe-catalyst ngokuya ngefomula ekhona yekhasimende
- Isiqondiso sepharamitha yenqubo: hlinzeka ngokushisa okuphezulu kwezinto ezibonakalayo, izinga lokushisa lesikhunta kanye nezinye izincomo zepharamitha ezibalulekile
- Ukuqalwa komugqa wokukhiqiza: Abasebenzi bezobuchwepheshe bazoqondisa ukuqala kokukhiqiza endaweni
