Cov yam ntxwv tseem ceeb ntawm cov khoom siv PET
PET (Polyethylene Terephthalate) has become the dominant material for beverage bottles thanks to its unique properties: Its dense molecular structure ensures excellent gas barrier performance, effectively preventing the escape of carbon dioxide; nws cov crystallinity nruab nrab endows lub raj mis lub cev nrog ib tug sib npaug ntawm toughness thiab pob tshab; thiab nws qhov kub thiab txias tsis kam ntawm -20℃txog 60℃raws li qhov xav tau ntawm kev siv txhua hnub. Tsis tas li ntawd, qhov purity ntawm cov khoom siv raw cuam tshuam ncaj qha rau kev nyiam huv thiab ruaj khov ntawm cov khoom kawg.
Cov ntsiab lus tseem ceeb hauv kev tsim khoom
Thaum lub tshuab molding txheej txheem, kev tswj qhov kub thiab txias txiav txim siab qhov sib xws ntawm lub raj mis phab ntsa thickness - qhov zoo tshaj plaws, qhov kub hloov pauv yuav tsum tau khaws cia hauv ± 3℃. Pwm precision tswj lub sealing kev ncaj ncees ntawm lub raj mis caj dab threads, thaum txhaj tshuaj siab thiab txias npaum li cas los txiav txim lub compressive zog ntawm lub raj mis puag. Hauv -kab tshuaj ntsuam xyuas kab ntawm cov kab ntau lawm saib qhov sib txawv ntawm qhov hnyav (feem ntau yuav tsum tsawg dua lossis sib npaug li 0.5g) thiab qhov yuam kev ntim (feem ntau lees txais hauv ± 2%) hauv lub sijhawm.
Tswv yim rau kev soj ntsuam zoo
Thaum tig lub raj mis tawm tsam lub teeb pom kev zoo, lub raj mis PET siab - zoo yuav tsis pom cov ripples lossis cov npuas huab cua; nias lub raj mis phab ntsa yuav tsum ua rau ib tug sai rebound, qhia cov khoom zoo elasticity; thiab ib qho kev poob dawb los ntawm qhov siab ntawm ib 'meter' - tom qab tau ntim nrog dej - yuav tsum tso lub raj mis kom zoo, ua kom pom qhov cuam tshuam txaus. Rau kev siv sijhawm ntev -, lub raj mis uas tseem tsis muaj huab cua thiab cov dej xau yog qhov cim tseeb ntawm tus qauv tsim uas ua rau lub sijhawm sim.
