Thaum kub siab, polypropylene tuaj yeem ua yaj hauv cov kuab tshuaj nonpolar xws li xylene ua tetralin thiab decalin.

Yog li ntawd, dab tsi yuav yaj polypropylene?

Polypropylene Nyob rau hauv chav tsev kub yog resistant rau cov rog thiab yuav luag tag nrho cov organic solvents, sib nrug los ntawm muaj zog oxidants. Thaum kub siab, PP tau yuav yaj hauv cov kuab tshuaj tsis xws li xylene, tetralin thiab decalin. Vim yog tertiary carbon atom PP yog tshuaj tiv thaiv tsawg dua PE (saib Markovnikov txoj cai).

Tsis tas li ntawd, puas acetone yaj polypropylene? Teb Chaws Keeb Kwm: Yuav ua li cas thiab yog vim li cas acetone tsis yog yaj polypropylene ? Vim li ntawd, acetone yuav tshwm sim tsis yog yaj nyob rau hauv tsis hnov mob nrog polypropylene (lossis feem ntau lwm cov kuab tshuaj organic rau qhov teeb meem, ib sab ntawm xylene/dimethylbenzene, tetralin lossis decalin ntawm qhov kub nce).

Xav txog qhov no, puas xylene yaj polyethylene?

Polyethylene (lwm yam tsis yog kev sib txuas polyethylene ) feem ntau tau ua yaj ntawm qhov kub thiab txias hauv cov ntxhiab hydrocarbons xws li toluene lossis xylene , los yog hauv cov kuab tshuaj chlorinated xws li trichloroethane lossis trichlorobenzene. Polyethylene absorbs yuav luag tsis muaj dej.

Puas yog polypropylene tawg?

Cov khoom ua los ntawm PP degrade maj mam nyob rau hauv landfills thiab siv sij hawm ib ncig ntawm 20-30 xyoo kom tag decompose. Rov ua dua Polypropylene yog qhov kev xaiv muaj txiaj ntsig zoo tshaj plaws los daws qhov xwm txheej no hauv txoj hauv kev zoo thiab muaj txiaj ntsig.
