Icyatsi gishya cyubuvuzi bushya: biodegradable PLA spunbond imyenda ifungura igihe cyo kurengera ibidukikije kubicuruzwa bivura imiti

Icyatsi kibisi nicyerekezo cyingenzi cyiterambere muri iki gihe, no kugaragara kwabiodegradable PLA (aside polylactique) spunbond imyenda idozeitanga uburyo bushya bwo kugabanya umuvuduko wibidukikije uterwa n’imyanda yo kwa muganga.

Ubuvuzi bukoreshwa na PLAT spunbond

Imyenda ya PLA spunbond yerekanye ubushobozi mubice byinshi byubuvuzi bitewe nibiranga:

Ibikoresho byo gukingira: Umwenda wa PLA spunbond urashobora gukoreshwa mugukora amakanzu yo kubaga, drape yo kubaga, imifuka yica udukoko, nibindi.

Ibicuruzwa bya antibacterial: Mugushyiramo antibacterial antorganic anticacterial nka nano zinc oxyde (ZnO) muri PLA, imyenda idoda idoda ifite antibacterial maremare kandi itekanye irashobora gutegurwa. Kurugero, iyo ZnO ibirimo 1.5%, igipimo cya antibacterial kurwanya Escherichia coli na Staphylococcus aureus gishobora kugera hejuru ya 98%. Ubu bwoko bwibicuruzwa burashobora gukoreshwa mugihe gikenewe cyane na antibacterial, nko kwambara kwa muganga, impapuro zo kuryamaho, nibindi.

Ibikoresho byo gupakira hamwe nibikoresho: PLA idoda idoda irashobora gukoreshwa mugupakira imifuka yibikoresho byubuvuzi. Guhumeka neza kwayo bituma imyuka ya sterilisation nka okiside ya Ethylene yinjira, mugihe ikumira mikorobe. PLA nanofiber membrane irashobora kandi gukoreshwa mubikoresho byo murwego rwohejuru.

Inyungu zidukikije nibibazo

Inyungu zikomeye zibidukikije: Gukoresha umwenda wa PLA spunbond bifasha kugabanya ikoreshwa ryumutungo wa peteroli nibicuruzwa bivura. Nyuma yo kujugunywa, irashobora kwangirika rwose mugihe cyifumbire mvaruganda, ikagira uruhare mukuzenguruka kwiza, kandi igafasha kugabanya kubungabunga ibidukikije n "umwanda wera" wimyanda yubuvuzi.

Inzitizi zahuye nazo: Kuzamura imyenda ya PLA spunbond murwego rwubuvuzi biracyafite imbogamizi. Kurugero, ibikoresho byiza bya PLA bifite ibibazo nka hydrophobicity ikomeye, imiterere yoroheje, kandi ikeneye kunoza ubushyuhe. Nyamara, ibyo bibazo bigenda bikemurwa buhoro buhoro binyuze muburyo bwo guhindura ibintu no gutezimbere inzira. Mugutegura fibre ya PLA copolymer, iyinjizwa ryayo nubushyuhe birashobora kunozwa. Guhuza PLA nizindi biopolymers nka PHBV nabyo byagaragaye ko aribwo buryo bwiza bwo kunoza imiterere yubukanishi no gutunganya.

Icyerekezo cy'iterambere ry'ejo hazaza

Iterambere ryimbere ryimyenda ya PLA spunbond murwego rwubuvuzi irashobora kugira inzira zikurikira:

Guhindura ibikoresho bikomeje kwiyongera: Mu gihe kiri imbere, ubushakashatsi buzakomeza kunonosora imitungo y’imyenda ya PLA spunbond binyuze muri copolymerisation, kuvanga, no kongeramo inyongeramusaruro (nko gukoresha imashini zangiza urunigi na antioxydants kugira ngo imikorere ya PLA), nko kunoza imikorere yayo, guhumeka, hamwe n’ubushuhe bw’amazi, kugira ngo byuzuze ibisabwa mu buvuzi.

Inganda zinganda niterambere ryikoranabuhanga: Iterambere ryiterambere ryaPLA imyendaYishingikiriza ku guhuza hafi inganda, amasomo, nubushakashatsi kugirango biteze imbere iterambere ryikoranabuhanga ryingenzi no kwagura inganda. Ibi bikubiyemo kunonosora ibishishwa bya kopi ya PLA no guteza imbere ikoranabuhanga rihoraho mu nganda zishingiye kuri SMS.

Uburyo bubiri bwo gushyigikira politiki hamwe n’ibisabwa ku isoko: Hamwe n’isohoka rya “gahunda yo guhagarika plastike” muri Hainan no mu tundi turere, ndetse no gushimangira isi yose ku iterambere rirambye n’ubukungu bw’umuzingi, politiki y’ibidukikije izakomeza gushyiraho isoko ryagutse ry’ibikoresho byangirika.

Incamake

Impuzu za PLA spunbond, hamwe nibyiza byo kurengera ibidukikije byatsi, ibikoresho fatizo bishobora kuvugururwa, ibinyabuzima bishobora kwangirika, hamwe nubushobozi bukora, bitanga amahitamo mashya mubikorwa byubuvuzi kugirango bigabanye umutwaro w’ibidukikije kandi biteganijwe ko bizatangiza igihe cyo kurengera ibidukikije kubicuruzwa byangiza imiti.

Nubwo iterambere rikomeje gukenerwa mu mikorere no kugenzura ibiciro, hamwe n’iterambere ry’ikoranabuhanga, gukura mu nganda, no guteza imbere politiki y’ibidukikije, ibyifuzo by’imyenda ya PLA spunbond mu rwego rw’ubuvuzi biratanga ikizere.

Nizere ko amakuru yavuzwe haruguru ashobora kugufasha kumva neza imyenda ya PLA spunbond. Niba ufite inyungu zubwoko bwihariye bwibicuruzwa byubuvuzi bya PLA, nkimyenda yo murwego rwohejuru irinda cyangwa imyambaro yihariye ya antibacterial, turashobora gukomeza gushakisha.

Dongguan Liansheng Ntabwo Yubatswe Ikoranabuhanga Co, Ltd.yashinzwe muri Gicurasi 2020.Ni uruganda runini rutunganya imyenda rudahuza ubushakashatsi niterambere, umusaruro, no kugurisha. Irashobora gutanga amabara atandukanye ya PP spunbond idoda idoda hamwe n'ubugari bwa metero 3.2 kuva kuri garama 9 kugeza kuri garama 300.
