Qhov txawv ntawm PP Yas thiab PE Yas
PP thiab PE yog ob yam khoom siv yas uas siv ntau, tab sis lawv txawv ntau hauv lawv daim ntawv thov. Cov ntu hauv qab no yuav piav qhia txog qhov sib txawv ntawm ob yam khoom no. Lub Npe Tshuaj Polypropylene Polyethylene Qauv Tsis Muaj Cov Qauv Saw Branching Qauv Saw Branched Qauv Ceev 0.89-0.91g / Cm³ 0.93-0.97g / Cm³ Melting Point 160-170 ℃ 120-135 ℃ Kev Tiv Thaiv Kub Zoo Kev Tiv Thaiv Kub Siab, Tuaj Yeem Tiv Thaiv Ntau Tshaj 100 ℃ Kub Siab Kev Tiv Thaiv Kub Siab Tsis Zoo, Feem ntau Tsuas Yog Tiv Thaiv 70-80 ℃ Kub Siab Kev Yooj Yim Siab Hardness, Tab sis Tsis Zoo Kev Yooj Yim Zoo, Nyeem Ntxiv ...
Qhov txawv ntawm LLDPE thiab LDPE
Qhov sib txawv ntawm linear low density polyethylene (LLDPE) thiab low density polyethylene (LDPE) 1. Kev txhais lus linear low density polyethylene (LLDPE) thiab low density polyethylene (LDPE) yog ob qho tib si cov khoom yas uas tau los ntawm ethylene ua cov khoom siv raw tseem ceeb. Txawm li cas los xij, lawv sib txawv ntawm cov qauv; LLDPE tau npaj siv cov thev naus laus zis catalyst ib leeg, ua rau muaj cov qauv linear thiab qhov ceev dua, thaum LDPE muaj cov qauv saw hlau tsis sib xws nrog qhov ceev qis dua. 2. Cov khoom siv lub cev LLDPE qhia txog qhov sib txawv ntawm qhov ceev Nyeem Ntxiv ...
Distinguishing High density polyethylene (HDPE) los ntawm LDPE
Polyethylene uas muaj qhov ceev siab (HDPE) thiab polyethylene uas muaj qhov ceev qis (LDPE) yog ob hom polyethylene polymers uas muaj cov yam ntxwv sib txawv. Nov yog qhov sib txawv tseem ceeb ntawm lawv: 1. Cov Qauv Molecular: HDPE muaj cov qauv linear nrog tsawg branching, ua rau muaj qhov ceev siab thiab crystallinity. LDPE, ntawm qhov tod tes, muaj cov qauv branched thiab tsis xwm yeem, ua rau muaj qhov ceev qis dua thiab crystallinity tsawg dua. 2. Qhov Ceev: Raws li lub npe qhia, Polyethylene uas muaj qhov ceev siab (HDPE) muaj qhov ceev siab dua piv rau qhov qis Nyeem Ntxiv ...
Dab tsi yog high density polyethylene yas?
Polyethylene siab ntom (HDPE) yog ib hom yas uas muaj nws lub zog siab rau qhov ceev. Nws feem ntau siv rau hauv ntau yam kev siv vim nws cov tshuaj tiv thaiv zoo heev, ruaj khov, thiab versatility. HDPE yog tsim los ntawm kev polymerization ntawm ethylene monomers, ua rau muaj cov saw hlau polymer nrog qib siab ntawm crystallinity. HDPE paub txog nws qhov ceev siab, uas muab nws lub zog zoo dua thiab rigidity piv rau lwm hom polyethylene. Nws muaj qhov ceev xws li ntawm 0.93 txog 0.97 Nyeem Ntxiv ...
Puas yog polyethylene yas?
Yog lawm, polyethylene yog ib hom yas. Nws yog ib qho polymer uas siv dav hauv ntau yam lag luam vim nws cov khoom tshwj xeeb thiab kev hloov pauv tau yooj yim. Polyethylene yog ib qho khoom siv sib dua, ruaj khov, thiab yoog tau uas tuaj yeem pwm tau yooj yim rau hauv ntau yam duab thiab cov duab. Polyethylene yog tsim los ntawm kev sib xyaw ua ke ntawm ethylene monomers. Ethylene yog cov roj hydrocarbon uas tau los ntawm cov roj ntuj lossis roj av.
