Xaiv lub raj yas yas tshuaj reagent yog qhov tseem ceeb hauv chav kuaj. Cia peb tshawb xyuas ob cov ntaub ntawv sib txawv - HDPE thiab PP: lawv cov txiaj ntsig thiab cov kev cuam tshuam nrog cov xwm txheej.
Cov Khoom Siv Khoom:
HDPE (siab ntom polyethylene): Cov ntaub ntawv no muaj qhov ua kom sov siab, ua rau muaj kev daws teeb meem tsawg thaum khaws cov kev daws teeb meem thaum {} {2}} degree.
PP (polypropylene): Tus Ntaus Brittleness Kub ntawm PP yog 0 degree, uas yog qhov tsim nyog dua rau cov khoom lag luam uas xav tau kev ntsuas kub.
Pob tshab:
Cov pob tshab ntawm PP zoo dua li ntawm HDPE, uas ua rau PP meej dua thaum saib xyuas lub xeev ntawm reagent.
Kev sib piv kev sib piv:
PP muaj cov kev cuam tshuam zoo tshaj, thiab nws cov khoom yas feem ntau muaj lub neej kev pab ntau dua li HDPE.
Txawm hais tias HDPE muaj qhov zoo dua-kub tsis kam, nws cov tawv yuav tsis tau zoo li PP.
Xaiv cov khoom siv yas cov ntaub ntawv yas tshuaj kom ua kom muaj kev nyab xeeb thiab kev pabcuam lub neej ntawm cov tshuaj reagents.
