Ukusetyenziswa kwelaphu le-polylactic acid engalukwanga kwizinto zokucoca umoya

I-Polylactic acid imathiriyeli yelaphu engalukiweyo inokudibanisa iingenelo zendalo ze-polylactic acid kunye neempawu zesakhiwo se-ultrafine fibers, indawo enkulu yendawo ethile, kunye ne-porosity ephezulu yemathiriyeli yelaphu engalukiweyo, kwaye ibe nethemba elibanzi lokusetyenziswa kwintsimi yokucoca umoya.

Ukusetyenziswa kweiasidi yepolylactic engalukwanga ilaphukushishino lokucoca umoya lunokwahlulwa ikakhulu kwizinto zokucoca imaski kunye nezixhobo zokucoca ezinobume bendalo (umsi wamashishini kunye nokucoca uthuli, ukucocwa komoya, ukukhuselwa komntu, njl. njl.).

Ke, zeziphi iingenelo kunye neempawu zokusebenzisa ilaphu le-polylactic acid engalukwanga njengelaphuizinto zokucoca umoya?

I-Biodegradability

Kwizixhobo zokucoca imaski, ukubola kwebhayoloji luphawu olubaluleke kakhulu. Umaleko wesihluzo semaski semveli usebenzisa ilaphu eliphindwe kabini elinyibilikayo lePP elingalukwanga, eliphantse lingonakali. Iimaski ezilahliweyo, nokuba ziqukuqela emilanjeni naselwandle okanye zingcwatywe emhlabeni, zibeka isoyikiso esikhulu kwi-ecosystem.

Umaleko wokucoca imaski eyenziwe ngawoizinto ze-polylactic acidayinakuhluza kuphela ngokufanelekileyo izinto ezinobungozi ezifana nothuli kunye neebhaktheriya ezisemoyeni, kodwa ziphinde zithobe emva kokusetyenziswa kunye nokulahlwa, ukunciphisa uxinzelelo kwi-ecosystem.
Xa iimveliso zefiber ye-polylactic acid zibonakaliswe kwindawo yendalo kunye nobushushu obuthile kunye nokufuma (okufana nesanti, intlenga, amanzi olwandle), i-polylactic acid inokuchithwa ngokupheleleyo kwi-carbon dioxide kunye namanzi nge-microorganisms. Ukuba i-polylactic acid fibers ingcwatywe emhlabeni, ixesha lokuthotywa kwendalo li malunga ne-2-3 iminyaka; Ukuba i-polylactic acid fibers ixutywe kunye nenkunkuma yezinto eziphilayo kwaye ingcwatywe, iya kubola kwiinyanga ezimbalwa.
Inkunkuma yemveliso ye-Polylactic acid inokubola ngokupheleleyo ibe yikharbon diokside kunye namanzi phantsi kweemeko zomgquba woshishino (ubushushu obungama-58 ℃, ukufuma 98%, kunye neemeko ze-microbial) kangangeenyanga ezi-3-6.

I-Antibacterial kunye ne-deodorizing agents

Ubuncinci befiber ye-polylactic acid buxhomekeke ekukwazini ukufikelela kuphela "ukuhluzwa ngokomzimba", kodwa kunye "nokuhlunga kwezinto eziphilayo". Umphezulu we-PLA ifayibha i-acidic ebuthakathaka, enokuthintela ukukhula kwee-microorganisms kunye nokunciphisa ukusasazeka kwe-allergens kunye neebhaktheriya emoyeni ukuya kwinqanaba elithile. Ngokubhekiselele kwi-deodorization, ikakhulu ixhomekeke kwi-asidi yayo ukutshabalalisa ubume beeseli zevumba elibangela iibhaktheriya, ukubulala ivumba elibangela iibhaktheriya, kunye nokufezekisa isiphumo sokuvumba.

Ngokusekwe kolu phawu, iimaski ezilahlwayo ze-polylactic acid ezine-biodegradable zineziphumo ezibalulekileyo zokukhupha ivumba kwaye zinokunxitywa ixesha elide ngaphandle kokuphefumla. Isetyenziselwa izixhobo zokucoca umoya wendlu, umoya ococekileyo uhlaziyekile kwaye awunavumba, ngelixa ukhusela ngokufanelekileyo izinto zokucoca ekubumbeni kunye nokunamathela, ukwandisa ubomi bayo benkonzo.

Ukusebenza kohluzo

Iifiber ze-Polylactic acid zineempawu ezithile zokucoca, kunye ne-fiber fineness kunye ne-cross-sectional shape inokuthi iyilwe ukwandisa ukuhamba komoya kunye nokubanjwa kwamasuntswana, ngokufanelekileyo ukuhluza amaqhekeza amancinci kunye nokungcola emoyeni.

Ukuphefumla okuphezulu

Uyilo lwesakhiwo se-polylactic acid fibers sinokufikelela ekuphefumuleni okuphezulu, ukuqinisekisa ukuhamba komoya ngaphandle kokuchaphazela ukusebenza kakuhle kokujikeleza komoya.

Amandla okuqina okuhle

Iintsinga ze-Polylactic acid zinamandla aphezulu okuxinana, okwenza umqhaphu wokucoca umoya womelele kwaye ungabikho lula kwi-deformation okanye umonakalo ngexesha lokusetyenziswa.

Amandla kunye nokuqina

Amalaphu angalukwanga enziwe kwimicu ye-polylactic acid anokufikelela ukomelela okuphezulu kunye nokuqina okugqwesileyo ukuhlangabezana neemfuno zokusonga kwezinye iimeko zesicelo.Ngenkqubela phambili yophuhliso lwentlalo kunye nolutsha lwezobuchwepheshe kushishino lwelaphu, izixhobo ze-polylactic acid ezinomsebenzi otyebileyo ziya kunika abasebenzisi ukhetho oluninzi.

Dongguan Liansheng Non woven Technology Co., Ltd.yasekwa ngoMeyi 2020. Lishishini elikhulu lemveliso yelaphu elingalukiweyo elidibanisa uphando nophuhliso, imveliso, kunye neentengiso. Inokuvelisa imibala eyahlukeneyo ye-PP spunbond amalaphu angalukwanga kunye nobubanzi obungaphantsi kwe-3.2 yeemitha ukusuka kwi-9 grams ukuya kwi-300 grams.
