Cov khoom ntawm BMC cov ntaub ntawv

1. Kev ua haujlwm dav dav: qhov tshwj xeeb lub ntiajteb txawj nqus ntawm BMC (DMC) loj dua, ntawm 1.3 ~ 2.1; Cov tsos ntawm cov khoom yog ci, qhov xav tau zoo, thiab muaj kev xav ntawm qhov nyuaj thiab hnyav; Cov cua kub nrog hluav taws ua rau cov pa roj ntau ntau thiab muaj cov ntxhiab tsw styrene; Qee hom BMC (DMC) tsis yog nplaim taws, tab sis qee hom yog cov nplaim taws heev, tawm hauv cov khoom tsis zoo tom qab combustion.

 

2. Dimensional stability: Lub linear expansion coefficient ntawm BMC (DMC) yog (1.3 ~ 3.5) × 10-5K-1, uas yog me dua li ntawm cov thermoplastics, yog li ntawd BMC (DMC) muaj siab. dimensional stability thiab dimensional precision. Qhov kub thiab txias tsis muaj qhov cuam tshuam me me rau qhov kev ruaj ntseg ntawm BMC (DMC), tab sis cov nyhuv ntawm cov av noo hnyav dua, thiab BMC nthuav dav tom qab nqus dej noo. Lub linear expansion coefficient ntawm BMC (DMC) yog ze heev rau cov hlau thiab txhuas, yog li nws tuaj yeem sib xyaw nrog lawv.

 

3. Mechanical zog: Lub tensile, dabtsi yog khoov, thiab cuam tshuam lub zog ntawm BMC (DMC) yog siab tshaj ntawm cov thermoplastics, thiab cov creep kuj tseem zoo dua li cov thermoplastics.

 

4. Dej thiab hnyav tsis kam: BMC (DMC) muaj kev tiv thaiv zoo rau dej, ethanol, aliphatic hydrocarbons, roj, roj, tab sis tsis tiv taus cov ketones, chlorine hydrocarbons, aromatic hydrocarbons, acids thiab alkalis, thiab lwm yam. BMC (DMC) muaj qhov nqus dej tsawg thiab kev ua haujlwm zoo rwb thaiv tsev tom qab ib hnub so.

 

5. Thaum tshav kub kub tsis kam: Lub tshav kub tsis kam ntawm BMC (DMC) zoo dua li ntawm cov khoom siv hluav taws xob dav dav, thiab cov cua sov deflection kub HDT yog 200 ~ 280 degree, uas tuaj yeem siv rau ntawm qhov kub ntawm 130 degree rau lub sijhawm ntev.

 

6. Kev laus tsis kam: BMC (DMC) muaj kev tiv thaiv kev laus zoo, nws tuaj yeem siv hauv tsev rau 15 ~ 20 xyoo, thiab nws lub zog tuav tus nqi yog ntau tshaj 60% tom qab 10 xyoo ntawm kev tawm sab nraum zoov.

 

7. Kev ua haujlwm hluav taws xob: BMC (DMC) muaj qhov zoo tshaj plaws arc tsis kam, uas tuaj yeem ncav cuag li 190 vib nas this.

 

8. Cov ntxhiab tsw qis: Cov styrene crosslinker siv hauv BMC (DMC) tseem yuav muaj 0.1% residue tom qab kho, thiab nws yuav tawm cov ntxhiab tsw phem thaum cua sov. Yog li ntawd, BMC (DMC) siv nyob rau hauv cov khoom noj khoom haus (xws li, microwave qhov cub tableware) yuav tsum tau ua los ntawm UP resin tsis muaj residue styrene monomer.
