Polyethylene Terephthalate (PET) Basic Introduction
Oct 31, 2024| Polyethylene terephthalate
nquag hu uaPET, yog polyester tseem ceeb tshaj plaws. PET muaj cov yam ntxwv ntawm kev ua pob tshab, amorphous thermoplastic thaum nws raug cua txias sai, thaum nws coj zoo li cov yas semicrystalline thaum txias qeeb lossis thaum txias txias. PET yog tsim los ntawm polycondensation ntawm ethylene glycol thiab terephthalic acid. PET tuaj yeem ua tiav siv cov txheej txheem molding xws li txhaj tshuaj molding, tshuab moulding thiab extrusion. Nws kuj tseem tsim nyog siv los tsim cov khoom nyias nyias xws li zaj duab xis ncab thiab thermoforming. PET yog dav siv los tsim cov pa roj carbon monoxide fwj vim nws muaj lub zog siab thiab tawv, zoo abrasion thiab kub tsis kam, tsis tshua nkag siab ntawm qhov kub siab, tshuaj lom neeg zoo thiab kev ruaj ntseg zoo heev. Lwm qhov kev nthuav dav ntawm PET yog ua cov khoom siv fiber ntau rau textiles (feem ntau pom nyob rau hauv cov khaub ncaws tag, sau li Polyester). Fibers ua los ntawm PET muaj qhov hnav tsis kam, tsis tshua muaj dej noo thiab ruaj khov heev.
Eco-profile ntawm plastics
Polyethylene terephthalate (PET) yog ib qho polymer uas ua los ntawm cov polymerization ntawm ethylene glycol thiab terephthalic acid.PETyog siv nyob rau hauv daim ntawv thov ntawm ntim thiab textile ntau lawm. Thaum xub thawj, cov khoom zoo heev ntawm kev ua haujlwm ntev, lub zog txhua yam thiab pob tshab ntawm PET ua rau nws siv rau hauv cov fwj carbonated haus. Txawm li cas los xij, lub neej luv luv, kev tsim khoom loj thiab tsis muaj biodegradability ntawm PET tau txais kev saib xyuas los ntawm ntau tus kws tshawb fawb, uas tau ua qhov kev ntsuam xyuas lub neej los soj ntsuam thiab ntsuas qhov cuam tshuam ib puag ncig ntawm PET ntim.
Physiochemical zog thiab degradation
Polyethylene terephthalate (PET) yog cov tshuaj polyester ruaj khov thiab nws cov kev siv tau nce siab heev hauv ob peb lub xyoo dhau los nrog ntau daim ntawv thov, xws li cov khoom noj thiab dej haus ntim rau kev tsim khoom siv hluav taws xob.176,196176196 thiab ua fibers hauv khaub ncaws. Feem ntau, cov raj mis PET rov siv dua yog siv los ua cov ris tsho fleece, nrog rau lub raj mis yas. Qhov tseeb, ib qho ntawm feem ntau siv PET yog nyob rau hauv kev tsim cov dej haus fwj thiab cov no tsis tu ncua pom littering hauv dej ib puag ncig.
