Waagii hore, walaxda wasakhaysan ee PFAS ee ku dahaadhay dusha gudaha ee baakadaha cuntada qaarkood waxay leedahay kansar gaar ah, sidaa darteed soo-saarayaal badan oo baakadaha cuntada degdega ah u sameeya ayaa u beddelay inay dusha sare ee warqadda ku dahaadhaan lakabka caagadaha xabagta ah sida PE, PP , EVA, sarin, iwm. Filimku wuxuu gaari karaa ujeedada biyuhu iyo saliid-celiya, kana fogaanayaan waxyeelada walaxda wasakhaysan ee PFAS caafimaadka aadanaha.Si kastaba ha noqotee, deegaanka dabiiciga ah, sida PFAS, qaab dhismeedka molecular ee filimaanta balaastikada ah waa mid deggan oo aan la dumin karin, sidaas darteed sameynta wasakh caag cad.Mareeyaha koobka warqadaha ee dahaarka leh ee #PE

Sidaa darteed, shirkadaha Shiinuhu waxay soo saareen oo ay soo saareen tignoolajiyada biodegradation-ka-ogsajiinta ee agabka polymer-ka (sida balaastikada, caagga, iyo fiilooyinka kiimikaad), kuwaas oo gaadhi kara wasakhaynta noole wasakhaysan iyo nabaad-guurka compost.

Masterbatch biodegradable Photo-oxygen waa tignoolajiyada ugu dhow ee xaalufinta degdega ah ee deegaanka dabiiciga ah.Ku darida 1% waxay gaari kartaa hoos u dhac degdeg ah iyada oo aan la beddelin walxaha, qalabka wax soo saarka, habka wax soo saarka iyo guud ahaan waxqabadka alaabta.

Si kastaba ha ahaatee, qiimaha polylactic acid PLA, PBAT, PBS, PHA iyo teknoolajiyada kale ee si buuxda biodegradable kordho ugu yaraan 100% ilaa 200%, iyo waxqabadka dhamaystiran ma gaari karo waxqabadka balaastikada dhaqanka, sidaas qalabka, qalabka wax soo saarka iyo hababka wax soo saarka. u baahan in wax laga beddelo.

Tiknoolajiyada biodegradation-ka-ogsajiinta ee filimaanta balaastikada ah sida PE iyo sarin waxaa loo isticmaali karaa soo saarida baakadaha cuntada degdega ah ee xaashida ee suuqa Shiinaha.Liiska warqadaha dahaarka leh ee #PE

Mabda'a farsamada ee tignoolajiyada biodegradation photo-oxygen

Shirkadda Shiinaha filimkeeda caagga ah ee tignoolajiyada biodegradation photo-oxidative waa nooc ka mid ah tignoolajiyada cusub ee biodegrade gabi ahaanba ku salaysan filimka caagga ah ee lagu tuuray deegaanka dabiiciga ah.Tiknoolajiyada waxaa loogu talagalay in ay sii haysato nolosheeda waxtarka leh sida badeecada iyo farsamada, farsamada, xannibaadda, daahfurnaanta iyo hantida kale ee ganacsiga inta lagu jiro wareegga nolosha, waxayna u ogolaataa filimada caagga ah inay biodegrade hoos yimaadaan xaaladaha dabiiciga ah ka dib markii la tuuray.

Tignoolajiyada ayaa ah in lagu daro masterbatch-ka-soo-saarka noole-ogsayjiinta ee sawir-qaadista filimka balaastiigga ah si looga dhigo inuu u dhaqmo sidii filim-oleefin caag ah oo sawir-oksijiin-bidegradable ah.Hagaajinta xawaaraha atamka oksijiinta la geliyo silsiladaha polymer-ka ee polymers-ka caagga ah.Polymers-ka caagga ah waxaa loo kala jejebiyaa walxo molecular oo yaryar oo ku jira jawi aerobic ah, ka dibna ay qurxiyaan microorganisms meel kasta oo ka mid ah deegaanka dabiiciga ah.Liiska hoose ee warqadda dahaarka leh ee #PE

Habka hoos u dhaca filimada caagga ah ee isticmaalaya tignoolajiyada biodegradation photo-oxygen waxaa loo qaybin karaa laba marxaladood.
Marxaladda koowaad: Filimka caagga ah ee lagu daray sawirka-oxygen biodegradable masterbatch wuxuu ka falceliyaa oksijiinta hawada, taasoo keenaysa wax lagu daro inuu weeraro silsiladda kaarboon ee polymer, iyo laf dhabarta kaarboon waa oksaydhized si ay u sameeyaan jajabyo molecular oo leh tiro molecular qaraabo ah in ka yar 10,000 ama ka yar (Saynisyahanada Yurub iyo Japan waxay aaminsan yihiin in oligomers leh cufnaanta molecular ka yar 400,000 ay liqi karaan microorganisms).

Marxaladdan, nabaad-guurku waa geeddi-socod abiotic ah, kaas oo kor u qaada gelinta atamka ogsijiinta ee lafta dhabarka kaarboonka halkaas oo polymer-ku uu jebiyo si uu u sameeyo kooxo kala duwan oo shaqeynaya (sida karboxilic acids, esters, aldehydes, iyo alkohols).

Polymer-ka molecular-ka sare waxa uu ka beddelaa silsiladda makromolecule hydrophobic una beddelo silsilad yar oo hydrophilic ah, taas oo ka dhigaysa jajabka silsiladda molecular si fudud in ay bakteeriyadu u naaxdo oo ay shiiddo.# taageere koobka warqadda alaabta ceeriin

Marxaladda labaad: microorganisms-ka meel walba ku nool (bakteeriya, fangaska iyo algae) ee dabiiciga ah waxay u jajabisaa filimka caagga ah sida ilaha nafaqo, ugu dambeyntiina waxay u jajabisaa carbon dioxide, biyo iyo biomass.Nabaad-guurka heerkan waxaa loo yaqaan habka biodegradation.

Imtixaanka iyo Heerarka

Haddi ay ahaan lahayd hawada furan ama shaybaadhka, heerka hoos u dhaca tignoolajiyadani waxa uu gaadhi karaa in ka badan 60%.Heerarka qaranka ee dalkayga GB/T 20197-2006 iyo GB/T 19277.1-2011, shuruudaha imtixaanka ugu sarreeya ee heerka biodegradation waa 60%.

Xaaladda shaybaarka, filimada leh dhumuc yar oo ka yar 15 μm, waxay geli karaan marxaladda biodegradation ka dib marka la barbardhigo bilaha 3 ee gabowga dabiiciga ah.Gabowga la isku daray ayaa dooran kara gabowga UV ama gabowga nalka xenon.

Gelitaanka marxaladda biodegradation, heerka ugu horumarsan ee hoos u dhaca polyolefin ee adduunka (PAS 9017: 2020) wuxuu u baahan yahay heerka hoos u dhaca in ka badan 90% gudaha 730 maalmood, taas oo aad uga sareysa heerka qaran ee dalkayga.

Heerka farsamada ee tignoolajiyada biodegradation-ka-oxidative ee filim caag ah ayaa aad uga sarreeya heerka qaran, kaas oo la jaan qaadaya heerka ugu sarreeya ee hoos u dhaca polyolefin ee adduunka (PAS 9017: 2020).

Ka dib markii la isku daro masterbatch biodegradable photo-oxygen galay resins caag ah sida PE iyo sarin, alaabta la soo saaray waxay leeyihiin sifooyin biodegradable, iyo 180-maalmood heerka biodegradation ay gaari karaan 60%, buuxinaya heerka qaranka GB/T 38082-2019 looga baahan yahay heerka biodegradation.Waxaa si buuxda u baabi'in kara xaaladaha hawo-furan, qashin-qashin ama bacriminta hawada.# PE xaashida dahaarka leh

Tignoolajiyada noolaynta noole-ogsayjiinta ayaa ka gudbi karta tijaabada heerarka qaran ee Shiinaha ee soo socda: GB/T 20197-2006, GB/T 19277.1-2011, GB/T 38082-2019.Iyadoo la raacayo siyaasadda iyo falsafada kaarboonka ee hadda jira.

Xulashada Jidadka Tignoolajiyada Biyo-xumada ee Dahaarka Kala duwan

Dahaarka EVA iyo daahan PP ayaa aad ugu habboon shirkadda Shiinaha ee (anaerobic + marine) tignoolajiyada biodegradation-ka, dabcan, tignoolajiyada sawir-oksijiinta ee shirkadda Shiinaha sidoo kale waa la isticmaali karaa.

Sarin resin, LLDPE, LDPE iyo dahaarka kale ayaa aad ugu habboon tignoolajiyada biodegradation sawir-oxygen ee shirkadaha Shiinaha.Dabcan, waxa kale oo suurtogal ah in la yareeyo heerkulka dhalaalka ilaa 310 °C si loo fududeeyo qaadashada (anaerobic + badda) tignoolajiyada biodegradation.#Nanning Dihui Paper Products Co., Ltd.
