Musiyano Wakakosha-UHMW vs HDPE
UHMW uye HDPE ndiwo thermoplastic polymers ane chitarisiko chakafanana.Musiyano wakakosha pakati peUHMW neHDPE ndewekuti UHMW ine macheni akareba epolymer ane uremu hwemamorekuru akanyanya asi HDPE ine reshiyo yesimba-kune-density.
UHMW inomirira Ultra High Molecular Weight polyethylene.Inotsanangurwa zvakare neUHMWPE.Izwi rokuti HDPE rinomirira High Density Polyethylene.
Chii chinonzi UHMW?
UHMW ndeye Ultra-yakakwirira molecular uremu polyethylene.Iyo imhando ye thermoplastic polymer.Iyi polima yepolymer ine cheni dzakareba kwazvo dzepolymer dzine huremu hwemamorekuru (akatenderedza 5-9 miriyoni amu).Naizvozvo, UHMW ine yakakwira molecular density.Nekudaro, chimiro chekomboni iyi hachizivikanwe kubva kune icho cheHDPE.

Cheni dzese dzepolymer muUHMW dzakareba kwazvo, uye dzinoenderana munzira imwe chete.Imwe neimwe polymer cheni inosungirirwa nemamwe akatenderedza polymer cheni kuburikidza neVan der Waal mauto.Izvi zvinoita kuti chimiro chese chiome zvakanyanya.
UHMW inogadzirwa kubva ku polymerization yemonomer, iyo ethylene.Iyo polymerization ye ethylene inoumba hwaro hwe polyethylene chigadzirwa.Chimiro cheUHMW chakasiyana zvakanyanya neiyo HDPE nekuda kwenzira yekugadzira.UHMW inogadzirwa pamberi pemetallocene catalyst (HDPE inogadzirwa pamberi peZiegler-Natta catalyst).

Chii chinonzi HDPE?
HDPE yakakwira density polyethylene.Iyo thermoplastic polymer zvinhu.Ichi chinyorwa chine huwandu hwepamusoro kana uchienzaniswa nemamwe marudzi e polyethylene.Kuwanda kweHDPE kunopihwa se 0.95 g/cm3.Sezvo dhigirii repolymer chain branching mune ino chinyorwa rakaderera kwazvo, macheni epolymer akazara zvakasimba.Izvi zvinoita kuti HDPE ive yakaoma uye inopa yakanyanya kukanganisa kuramba.HDPE inogona kubatwa pasi petembiricha yakatenderedza 120°C pasina chero chinokuvadza.Izvi zvinoita kuti HDPE iite autoclavable.

Ndeapi Kufanana Pakati peUHMW neHDPE?
UHMW uye HDPE inogadzirwa ne ethylene monomers.
Ose ari maviri thermoplastic polymers.
Zvose zvine chitarisiko chisingaoneki.
| UHMW vs HDPE | |
| UHMW ndeye Ultra-yakakwirira molecular uremu polyethylene. | HDPE yakakwira density polyethylene. |
| Chimiro | |
| UHMW ine macheni akareba kwazvo epolymer. | HDPE ine mapfupi polymer cheni zvichienzaniswa neUHMW. |
| Molecular Weight yePolymer Chains | |
| Iyo polymer cheni yeUHMW ine yakakwira zvakanyanya mamorekuru. | Iyo polymer cheni yeHDPE ine yakaderera mamorekuru uremu kana ichienzaniswa neUHMW. |
| Kugadzirwa | |
| UHMW inogadzirwa pamberi pe metallocene catalyst. | HDPE inogadzirwa pamberi peZiegler-Natta catalyst. |
| Kutora Mvura | |
| UHMW haitore mvura (zero absorption). | HDPE inogona kutora mvura zvishoma. |
Summary-UHMW vs HDPE
Ose ari maviri UHMW uye HDPE akagadzirwa ethylene monomers kuburikidza nepolymerization.Musiyano wakakosha pakati peUHMW neHDPE ndewekuti UHMW ine macheni akareba epolymer ane uremu hwemamorekuru akanyanya asi HDPE ine reshiyo yesimba-kune-density.
