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.

Puas yog cov quav yaj zoo rau cov nyom?
Yog tias koj xav tau cov chiv uas yooj yim thov, cov yaj thiab quav tshis yog tus yeej. Vim tias lawv qhuav, lawv yooj yim zom thiab nchuav rau ntawm koj cov nyom lossis sib xyaw nrog lwm cov khoom xyaw. Zoo li quav qaib, lawv muaj nitrogen ntau, tab sis lawv tsis hnov ntxhiab thiab tsis hlawv cov nyom ntau npaum li lwm hom chiv tuaj yeem ua tau
Puas yog yaj quav quav zoo rau tsob ntoo txiv ntoo?
Tsiaj quav quav yog ua tiav, natural fertilizer. Nqaij qaib thiab yaj quav muaj li ob npaug ntau npaum li nitrogen cov ntsiab lus li nees lossis nyuj quav. Tus nqi ntawm cov chiv tsim nyog rau koj tsob ntoo yuav nyob ntawm lub hnub nyoog thiab qhov loj ntawm tsob ntoo. Fertilize ntoo thaum ntxov caij nplooj ntoos hlav kom lawv siv tau cov as-ham thaum lub sij hawm loj hlob
Puas yog roj yaj Styrofoam?
Tag nrho cov roj (ntses roj, roj txiv roj, roj canola, thiab lwm yam) yuav yaj Styrofoam nrog lub sijhawm txaus. Qee hom ntses roj yuav yaj Styrofoam sai heev. Lwm tus ua nws qeeb qeeb. Qhov kev cuam tshuam no, thiab qhov ceev ntawm qhov nws tshwm sim, yog vim muaj cov khoom siv tshuaj hu ua polarity
Puas yog acetone yaj HDPE?
Polyethylene tshwm sim nyob rau hauv ob hom: siab ceev thiab tsawg ntom polyethylene paub raws li HDPE thiab LDPE. Ob daim ntawv ntawm polyethylene yog heev resistant rau acids, caustic alkaline kua thiab inorganic kuab tshuaj. Txawm li cas los xij, qee cov kuab tshuaj organic xws li benzene thiab acetone tuaj yeem yaj polyethylene
Puas yog polypropylene ntaub pua plag puas lom?
Polypropylene cov ntaub pua tsev muaj cov khoom siv tshuaj lom neeg uas thaum nqus tau tuaj yeem ua rau qee yam teeb meem xws li mob taub hau, ua xua, kiv taub hau, lossis xeev siab. Qee lub sij hawm lawv nyiam emit volatile organic compounds (VOCs) uas yuav outgas. Cov pa roj no yog "cov ntaub pua plag tshiab" uas koj tau txais thaum cov ntaub pua plag tshiab
