Kev Hloov Kho Biodegradable Polyester

Biodegradable fiber yog cov xov paj polyester tshwj xeeb muaj peev xwm biodegrade ib txwm nyob hauv qhov chaw pov tseg. Kev biodegradability yog ua tiav los ntawm kev khawb cov catalyst (ntxiv) rau cov polymer ua ntej cov xov paj tau extruded. Cov tshuaj ntxiv ua kom nrawm nrawm biodegradation hauv qhov chaw pov tseg los ntawm kev nyiam ntau dua 600 hom kab mob microbes uas pub rau nws. Qhov ntxiv tsis muaj kev cuam tshuam rau lub cev lub cev ntawm cov xov.

Cov khoom siv biodegradable tsis xav tau kev ua tshwj xeeb ua ntej lawv muab pov rau hauv qhov chaw pov tseg. Cov khoom siv muaj peev xwm pib nyiam cov kab mob anaerobic sai li sai tau thaum lawv pov rau hauv qhov chaw pov tseg.

Cov tshuaj ntxiv ua rau cov ntaub ntawv ntau dua hydrophilic thiab nyiam cov microbes coob uas' pub rau' hloov kho polymer hauv qhov chaw pov tseg. Cov enzymes uas cov microbes tsim tawm tsam nrog cov tshuaj ntxiv, sib koom ua ke catalysing txheej txheem biodegradation.

Cov khoom xyaw nquag hauv cov xov paj no tsis txhawb nqa biodegradation thaum lub sijhawm ua haujlwm ntawm cov ntaub. Nws tsuas yog pib ua haujlwm thaum cov ntaub raug pov tseg rau hauv qhov chaw pov tseg.

Cov xov paj zoo li no tau txais txiaj ntsig zoo hauv kev sim tshuaj uas qhia tias ntau dua 25% biodegradation tau tshwm sim tsawg dua tsib lub hlis thaum, nyob rau tib lub sijhawm, cov ntaub polyester tsis tu ncua yuav poob qis tsuas yog 0.6% raws li qhia hauv biodegradation profile hauv qab no.

Biodegradation Profile

√ Kev tswj kom zoo: tsim cov khoom siv biodegradable (cellulose) kom paub tseeb tias cov inoculum tau coj zoo li qhov xav tau

√ Kev tswj tsis zoo: tsim kom muaj cov khoom tsis muaj biodegradable (polyethylene) (degrades ib ncig 1% lossis tsawg dua hauv ib xyoos).

Biodegradable npuag yog qhov hloov pauv tshiab rau kev hnav khaub ncaws lossis ncaws pob ua lag luam, txij li ntau thiab ntau tus neeg lossis nyiam ncaws pob ntau dua tsom mus rau kev tiv thaiv ib puag ncig. Peb ua tiav tsim biodegradable interlock thiab tsho rau cov lag luam xav tau.
