Cov ntaub ntawv yas hauv qab no tuaj yeem siv rau hauv thermal molding:
Polystyrene
suav nrog lub hom phiaj dav dav (GPPS), muaj kev cuam tshuam siab (HIPS) thiab qib biaxially oriented (BOPS), haum rau pob tshab ntim ntim, tais, npog, thiab lwm yam. Nws muaj cov yam ntxwv ntawm qhov siab hardness thiab zoo transparency, tab sis nws yuav tsum tau hloov kho los txhim kho nws qhov cuam tshuam.
Polyvinyl chloride (PVC)
Muab faib ua nruj thiab yoog raws. Rigid PVC feem ntau yog siv rau hauv cov thawv ntim khoom noj vim nws qhov nruj thiab tus nqi qis, thaum PVC mos mos yog haum rau cushions thiab hnab nyiaj vim nws yooj. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias nws cov thermal stability yog qhov tsis zoo thiab kev tswj kub yuav tsum tau ua thaum ua.
Polyolefin
- Polyethylene (PE): Xws li cov khoom siv high-density polyethylene (HDPE) thiab tsawg ntom polyethylene (LDPE) nrog cov kub tsis tshua muaj zog thiab nqus dej tsawg, haum rau cov khoom siv hauv chav kuaj, cov khoom siv hauv chav ua noj, ntim ntim, thiab lwm yam.
- Polypropylene: Cov cua kub zoo heev thiab kev ua haujlwm hluav taws xob zoo, haum rau cov thawv microwave, cov khoom siv kho mob, thiab lwm yam. Nws cov thermoforming kub yuav tsum yog 5-50℃saum lub melting point los txhim kho qhov seem stability.
- Polyethylene terephthalate: Siab tensile lub zog, lub teeb yuag, recyclable, notabsorbent, tsis muaj tshuaj lom neeg cov tshuaj tiv thaiv nrog zaub mov, dav siv nyob rau hauv cov zaub mov ntim, xws li haus fwj, blister ntim.
- Engineering plastics: Acrylonitrile-butadiene-styrene copolymer (ABS): tawv, tawv, kub resistant, haum rau aircraft canopies, nws pib qhov chaw thiab cov khoom vaj tse.
- Polycarbonate: High light transmittance and impact resistance for aircraft canopies, lampshades thiab khoom kho mob.
- Polymethacrylate (PMMA, plexiglass): siab transparency, zoo aging kuj, haum rau lampshades, qab nthab thiab cov khoom siv tshuaj.
- Cellulose Plastics: Fiber acetate: zoo toughness, muaj feem xyuam rau lub zog, haum rau pob tshab ntim ntim thiab exhibition ntim. Thaum lub sij hawm ua, yuav tsum tau them nyiaj mloog mus rau lub evaporation ntawm plasticizers, uas yuav daws tau los ntawm kev ntxiv vents los yog siv cov pwm zoo.
Lwm yam khoom siv tshwj xeeb
- Polyamide (PA, nylon): Zoo toughness, abrasion kuj thiab kub tsis kam rau cov khoom ntim xws li ntses.
- Polylactic Acid (PLA): Cov khoom siv biodegradable haum rau cov khoom siv sab nrauv thiab cov khoom siv biomedical.
