Khoom Taw qhia
Peb componment MDI system PU Prepolymer
1. Cov yam ntxwv ntawm MDI raw khoom
Tib cov ntaub ntawv raw tuaj yeem tsim nrog qhov sib txawv hardness los ntawm kev kho qhov sib piv A / B / C, thiab cov khoom siv raw yuav tsum tsis txhob hloov pauv hauv cov txheej txheem hardness hloov.
1) Xav tau kev cuam tshuam catalyst
MDI peb-khoom noj khoom haus muaj nyob rau hauv semi-prepolymer, thiab cov tshuaj tiv thaiv ntawm-0H tsawg dua li ntawm-NH2. Txhawm rau kom tau txais cov khoom zoo ntawm lub cev thiab kev ua haujlwm ntau lawm, catalyst yog xav tau
2) Kev tiv thaiv ib puag ncig
Lub vapor siab ntawm MDI yog qis dua li ntawm TDI, thiab nws muaj ntxhiab tsw ntxhiab thiab me ntsis toxicity nyob rau hauv cov txheej txheem ntau lawm, yog li MDI yog cov khoom tshiab uas ua tau raws li qhov xav tau ntawm kev tiv thaiv ib puag ncig.
2. Qhov zoo ntawm MDI peb-tiv thaiv series
* Adjustable hardness: tib qib ntawm peb cov khoom siv raw tuaj yeem hloov pauv los ntawm kev hloov pauv thiab kev sib xyaw ua ke los tsim cov khoom sib txawv hardness.
* Kev tiv thaiv ib puag ncig: MDI vapor siab qis dua.
* Cov cuab yeej siv hluav taws xob tsawg: Daim ntawv thov kub ntawm MDI cov khoom qis dua, thiab cov cuab yeej siv hluav taws xob tau txo qis heev.
* Kev ua haujlwm siab ntau lawm: Kev cuam tshuam ntawm cov catalyst ua rau kev tsim khoom ntawm MDI cov khoom siab dua li cov khoom siv TDI, nrog kev siv hluav taws xob tsawg thiab kev ua haujlwm siab.
