PP qhov chaw

• Polypropylene resin yog ib qho ntawm plaub lub hom phiaj thermoplastic resins (polyethylene, polyvinyl chloride, polypropylene, thiab polystyrene), uas yog tsim los ntawm polymerization siv propylene li raw khoom thiab ethylene li comonomer.
• Kev ua haujlwm kub zoo, kev siv kub tsis tu ncua mus txog 110-120 degree .
• Cov khoom siv zoo heev, suav nrog lub zog tensile, compressive zog, thiab hardness, zoo heev rigidity thiab khoov qaug zog kuj. Lub pob khawm txav tau ua los ntawm PP tuaj yeem tiv taus 7 × Ntau tshaj 107 folds thiab khoov yam tsis muaj kev puas tsuaj, ua rau muaj kev cuam tshuam tsis zoo ntawm qhov kub thiab txias. Lub zog tensile ntawm PP feem ntau yog 21-39 MPa; dabtsi yog khoov lub zog 42-56 MPa, compressive zog 39-56 MPa, elongation ntawm tawg 200 feem pua ​​~ 400 feem pua, notch impact zog 2.2-5 kJ/m2, low-temperature notch impact strength {{11 } kJ/m2. Rockwell hardness R95 ~ 105.

Raws li ib qho ntawm cov ua pp qhov chaw manufacturers thiab lwm tus neeg nyob hauv Suav teb, peb sov siab txais tos koj mus yuav cov khoom pheej yig pp qhov chaw los ntawm peb lub hoobkas. Tag nrho cov khoom yog nrog cov khoom zoo thiab tus nqi qis. Rau kev hais lus, tiv tauj peb tam sim no.
