Breathble pla spunbond nonwoven Isithombe Esifakiwe

I-pla spunbond ephefumulayo engalukiwe

Njengamanje, i-polypropylene (PP) iseyinto eyinhloko esetshenziselwa izindwangu ezingezona ezilukiwe, futhi izakhiwo zayo zokuwohloka azihlangabezani nezidingo zokuvikelwa kwemvelo nokuthuthukiswa okuqhubekayo. Ukukhuthaza ukusetshenziswa kwezinto ezibolayo emkhakheni wezindwangu ezingalukiwe kuzoba umkhuba. Izindwangu ezihlukene ezingalukiwe ezenziwe nge-polylactic acid ziyakwazi ukubola, futhi ezinye zixuba i-polylactic acid neminye imicu yemvelo noma imicu yokwenziwa ukuze umkhiqizo wokugcina ungaboli.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-Polylactic acid (PLA) iwuhlobo olusha lwezinto ezibolayo ezenziwe ngesitashi ezitholakala ezinsizeni zezitshalo ezivuselelekayo njengommbila. Izinto ezisetshenziswayo zesitashi ziyashiswa ukuze kutholwe i-glucose, esuke ivutshelwa ngezinhlobo ezithile ukuze kukhiqizwe i-lactic acid emsulwa. Khona-ke, isisindo esithile samangqamuzana e-polylactic acid sihlanganiswa ngezindlela zamakhemikhali. Ine-biodegradability enhle futhi ingacekelwa phansi ngokuphelele ama-microorganisms emvelweni ngemva kokusetshenziswa, ekugcineni ikhiqize isikhutha namanzi ngaphandle kokungcolisa imvelo.

Lokhu kuzuzisa kakhulu ekuvikeleni indawo ezungezile futhi kuqashelwa njengento ehambisana nemvelo. Ukunakekela Umhlaba, sinomthwalo wemfanelo. Ngokwemibiko yezindaba, ukukhishwa kwe-carbon dioxide emhlabeni wonke kulindeleke ukuthi kunyukele ku-60 ℃ ngo-2030. Indlela yokwelapha amapulasitiki avamile isashiswa nokushiswa, okubangela ukuba kukhishelwe inqwaba yamagesi abamba ukushisa emoyeni. Ngakolunye uhlangothi, amapulasitiki e-Polylactic acid agqitshwa emhlabathini ukuze acekelwe phansi, akhiqize i-carbon dioxide engena ngqo enhlabathini yezinto eziphilayo noma emuncwa izitshalo, ngaphandle kokukhishwa emoyeni noma kubangela umphumela obamba ukushisa.

Izici ze-PLA polylactic acid Indwangu engalukiwe

Ubufakazi bomswakama, obuphefumulayo, obuvumelana nezimo, obungasindi, obungashi, kulula ukubola, obungewona ubuthi futhi obungacasuli, onothile ngombala, obusebenzisekayo.

Isibonelo sohlelo lokusebenza lwendwangu engalukiwe ye-PLA

Ukuthatha ukusetshenziswa kwezindwangu ezingezona ezilukiwe emkhakheni wezokwelapha nempilo njengesibonelo, izindwangu ezingezona ezilukiwe ze-PLA azigcini nje ngokuhlangabezana ngokugcwele nezidingo zokuphepha nokusetshenziswa kwezinto zokuzivikela ezilahlwayo, kodwa futhi zinikeza umkhiqizo izici ezintsha eziluhlaza kanye nemvelo. Ngemuva kokusetshenziswa, ingahle iguqulwe ngokuphelele ngaphansi kwezimo zokufaka umquba phakathi nezinyanga ezimbalwa, hhayi nje ngaphandle kokubangela noma yimuphi umthwalo emvelweni, kodwa futhi nokubamba iqhaza ekujikelezeni kwemvelo.

Ngaphezu kwalokho, indwangu ye-polylactic acid ulwelwesi luyinto entsha esekelwe ezintweni eziphilayo enokuzwakala kwesandla esithambile, isikhangiso esinamandla, ukugcinwa komswakama, ukuphefumula kanye ne-bacteriostasis. Ihlanzekile, iphephile, inempilo futhi isondelene nesikhumba sekhwalithi ephezulu. Inezici eziningi zebhayoloji amanye ama-substrates angakwazi ukuzifanisa, futhi iyindawo ekahle ye-mask yobuso yekhwalithi ephezulu.
