Txheej txheem cej luam
Yuav luag txhua qhov chaw ntawm lub neej niaj hnub no muaj kev koom tes ntawm cov ntaub ntawv polymer, uas tau ua kom yooj yim rau tib neeg, tab sis ntau cov khoom siv polymer ib txwm siv tom qab siv cov khoom pov tseg tsis zoo (dawb paug) muaj kev pheej hmoo loj rau ib puag ncig, thiab kev nce ntxiv txhua xyoo. Kev siv cov khoom siv biodegradable es tsis txhob siv cov ntaub ntawv polyolefin ib txwm siv, thaum khaws cov khoom yooj yim ntawm cov ntaub ntawv polymer, tab sis kuj kom ua tiav qhov kawg ntawm kev siv lub voj voog, lub ntuj puag ncig, decomposition ntawm ib puag ncig tsis muaj kev cuam tshuam rau ib puag ncig, los daws qhov nce ntxiv hauv ib puag ncig lub nra tshwj xeeb hauv ntim, kho mob, khw hnab / hnab khib nyiab, mulch, thiab lwm yam, biodegradable cov ntaub ntawv muaj peev xwm loj hlob. Shanghai lub koom haum tshawb fawb aliphatic aromatic copolyesters (PBAT, PBST) polylactic acid (PLA), polyhydroxy fatty acid ester (PHAs) bio-raws li plastics (TPS, TPC) thiab lwm tus neeg sawv cev ntawm tag nrho cov biodegradable cov ntaub ntawv, los ntawm kev nruam yaj extrusion viscosification, lub cev / tshuaj hloov kho cov khoom thiab lwm yam, kev npaj cov khoom tshwj xeeb ntawm cov ntaub ntawv kev ua tau zoo, kev ua tau zoo ntawm cov ntaub ntawv tshwj xeeb. realizing daim ntawv thov nyob rau hauv tag nrho biodegradable mulch zaj duab xis, khw hnab / hnab khib nyiab, nthuav qhia ntim, los ntawm kev qhia txog biomass Cheebtsam (cov ntsiab lus tuaj yeem ncav cuag 50%), cov khoom siv tsawg dua - carbon thiab environmentally friendly, qee cov khoom tseem ceeb dua, thiab tus nqi sib tw ntau dua. Los ntawm kev sib raug zoo nrog cov khoom siv raw khoom tsim khoom lag luam, tag nrho cov saw kev pab cuam los ntawm cov khoom siv raw kev hloov pauv mus rau kev tsim khoom thiab kev tsim khoom tau ua tiav, thiab cov peev txheej ntawm cov teb koom nrog tau mus txog 1,000 tons.
Biodegradable PHA mulch tag nrho
Los ntawm kev sib xyaw cov khoom tshiab PHA cov khoom tsim los ntawm Tsinghua University nrog rau cov yaj tas mus li ntawm cov khoom siv biodegradable polymer, ntau yam khoom tshwj xeeb rau cov yas zaj duab xis biodegradable uas haum rau cov yam ntxwv ntawm huab cua sib txawv. Theultra-nyias, siab{2}}lub zog, thiab siab-toughness tag nrho biodegradable PHA yas zaj duab xis yog tsis tu ncua thiab ruaj khov npaj nyob rau hauv industrial qib yas zaj duab xis ntau lawm kab, uas tau siv nyob rau hauv ntau tshaj 10 lub xeev thiab lub zos nyob rau hauv Suav teb. Nws tau ua lub luag haujlwm zoo hauv kev ruaj khov thiab nce ntau lawm.
Biodegradable tag nrho, adjustable kev pab cuam lub neej ntawm 2-4 lub hlis;
Film thickness: 4-6 microns, tensile strength >35MPa, elongation at break >650%, ua tau raws li qhov yuav tsum tau ua ntawm txhua yam zaj duab xis tso.
Kev txhawb nqa thiab kev thov
Siv cov khoom siv biodegradable PBXT (xws li PBAT thiab PBST) cov khoom sib txuas ntawm 20,000 tuj cov kab ntau lawm ntawm Sinopec Yizheng Chemical Fiber, peb tsim cov qauv crystallization tshiab thiab cov txheej txheem los txhim kho crystallization zog ntawm PBXT cov ntaub ntawv thiab tsim ib qho kev nruam yaj extrusion viscosification technology rau viscosification zoo heev. nws tseem tuaj yeem txhim kho thiab txhim kho kev ua haujlwm xws li qhib thiab lubricity raws li qhov xav tau. Tsim ib qho -kauj ruam txoj hauv kev kom tsis tu ncua npaj qis- nqi ntsuab biodegradable zaj duab xis tshwj xeeb cov khoom siv thev naus laus zis, los ntawm kev qhia txog li 50% biomass Cheebtsam, txo cov nqi ntawm PBXT cov ntaub ntawv, thiab txhim kho cov khoom sib tw.
Biodegradability ua tau raws li qhov yuav tsum tau ua, melting Performance index 3-5g / 10min;
Zaj duab xis thickness ntawm 10-100 microns tuaj yeem hloov kho raws li qhov xav tau;
The elongation at break of the film was >500%, the breaking strength was >20 MPa; Cov ntsiab lus biomass yog 20% -50% adjustable ntawm kev thov.
