Taw qhia
Cov yas degradable yog hais txog ib hom yas uas nws cov khoom muaj peev xwm ua tau raws li cov kev xav tau ntawm kev siv, qhov kev ua tau zoo tsis hloov pauv thaum lub sij hawm khaws cia, thiab tuaj yeem degraded rau hauv ib puag ncig tus phooj ywg tshuaj nyob rau hauv tej yam ntuj tso tej yam kev mob tom qab siv. Yog li ntawd, nws tseem hu ua ib puag ncig degradable yas.
Muaj ntau yam tshiab plastics: photodegradable plastics, biodegradable plastics, photo/oxidation/biodegradable plastics, carbon dioxide-based biodegradable plastics, thermoplastic starch resin degradable plastics.
Polymer degradation yog hais txog cov txheej txheem ntawm kev rhuav tshem cov saw hlau macromolecular ntawm polymerization los ntawm cov tshuaj lom neeg thiab lub cev. Cov txheej txheem degradation nyob rau hauv uas polymers raug rau tej yam kev mob xws li oxygen, dej, hluav taws xob, tshuaj, pa phem, mechanical rog, kab thiab lwm yam tsiaj, thiab microorganisms yog hu ua ib puag ncig degradation. Kev degradation txo qhov hnyav molecular ntawm cov polymer thiab txo lub cev lub cev ntawm cov khoom siv polymer kom txog thaum cov khoom siv polymer poob nws qhov kev siv, ib qho tshwm sim tseem hu ua kev laus degradation ntawm cov khoom siv polymer.
Kev laus degradation ntawm polymers yog ncaj qha ntsig txog kev ruaj ntseg ntawm polymers. Kev laus degradation ntawm polymers shortens lub neej kev pab cuam ntawm plastics.
Txij li thaum lub advent ntawm plastics, cov kws tshawb fawb tau cog lus rau kev tiv thaiv kev laus ntawm cov ntaub ntawv zoo li no, uas yog, kev tshawb fawb ntawm kev ruaj khov, txhawm rau tsim cov khoom siv polymer ruaj khov, thiab cov kws tshawb fawb hauv ntau lub teb chaws kuj tseem siv cov kev laus degradation tus cwj pwm. polymers los tsim ib puag ncig degradation plastics.
Cov ntaub ntawv tseem ceeb ntawm cov yas degradable yog: ua liaj ua teb mulch zaj duab xis, ntau hom hnab ntim hnab, hnab khib nyiab, hnab khw hauv khw hauv khw thiab cov khoom noj khoom haus pov tseg.
Degradation tswvyim
Cov txheej txheem degradation ntawm ib puag ncig degradable plastics feem ntau suav nrog biodegradation, photodegradation thiab tshuaj degradation, thiab peb lub ntsiab degradation txheej txheem no muaj kev sib koom ua ke, sib koom ua ke thiab sib koom ua ke. Piv txwv li, photodegradation thiab oxide degradation feem ntau mus ib txhij thiab txhawb ib leeg; Biodegradation feem ntau yuav tshwm sim tom qab cov txheej txheem photodegradation.
Yav tom ntej Trend
Qhov kev thov ntawm cov yas degradable yuav tsum nce ntxiv mus, thiab maj mam hloov feem ntau ntawm cov khoom siv yas ua.
Muaj ob lub laj thawj tseem ceeb uas ua rau qhov no, 1) Kev paub txog pej xeem kev paub txog kev tiv thaiv ib puag ncig txhawb ntau tus neeg hloov mus rau hauv cov khoom lag luam eco. 2) Kev txhim kho ntawm thev naus laus zis txo qis tus nqi tsim khoom ntawm cov khoom yas biodegradable. Txawm li cas los xij, tus nqi siab ntawm degradable resins thiab kev ua haujlwm ruaj khov ntawm lawv cov lag luam los ntawm ntau yam yas uas twb muaj lawm ua rau nws nyuaj rau biodegradable plastics nkag mus rau hauv kev ua lag luam. Yog li ntawd, cov yas biodegradable yuav tsis muaj peev xwm hloov cov yas ib txwm nyob rau hauv luv luv tun.
Kev lees paub: tag nrho cov ntaub ntawv thiab cov ntaub ntawv tau txais los ntawm Ecopro Manufacturing Co., Ltd suav nrog tab sis tsis txwv rau cov khoom tsim nyog, cov khoom siv, kev ua yeeb yam, yam ntxwv thiab tus nqi yog muab rau cov ntaub ntawv xov xwm nkaus xwb. Nws yuav tsum tsis txhob muab suav hais tias yog khi specifications. Kev txiav txim siab txog qhov tsim nyog ntawm cov ntaub ntawv no rau ib qho kev siv tshwj xeeb yog lub luag haujlwm ntawm tus neeg siv. Ua ntej ua haujlwm nrog ib qho khoom siv, cov neeg siv yuav tsum hu rau cov chaw muab khoom, lub koomhaum tseemfwv, lossis lub koomhaum pov thawj kom tau txais cov ntaub ntawv tshwj xeeb, ua tiav thiab cov ncauj lus kom ntxaws txog cov khoom uas lawv xav txog. Ib feem ntawm cov ntaub ntawv thiab cov ntaub ntawv yog genericized raws li kev lag luam cov ntaub ntawv muab los ntawm cov khoom siv polymer thiab lwm qhov yog los ntawm kev soj ntsuam ntawm peb cov kws tshaj lij.
