Ilaphu le-Biodegradable polypropylene composite spunbond nonwoven

Ngenxa yekhabhoni egcweleyo yebhondi yemolekyuli yepolypropylene, ubume bayo bemolekyuli buzinzile kwaye kunzima ukuthotywa ngokukhawuleza. Ngelixa eli laphu lilula le-polypropylene spunbond nonwoven lizisa lula kwimveliso kunye nobomi babantu, likwabangela ungcoliseko oluthile lokusingqongileyo. Ke ngoko, ukulungiswa kunye nophando lwelaphu elinobungane kunye ne-biodegradable polypropylene composite spunbond nonwoven nonwoven kubaluleke kakhulu. Iasidi yePolylactic yipolymer enokubola ngebhayoloji egqwesileyo kunye neempawu zoomatshini. Inokudityaniswa kunye nemathiriyeli ekrwada ye-polypropylene ukulungiselela amalaphu e-polypropylene ahlanganisiweyo e-spunbond angalukwanga, ngokwenjenjalo kuncitshiswa ungcoliseko lokusingqongileyo olubangelwa ngamalaphu e-polypropylene spunbond angalukwanga.

Ukusebenza kwelaphu le-polypropylene elidityanisiweyo le-spunbond elingalukwanga

Kwinkqubo yokulungisa ilaphu le-polypropylene elinokonakala le-biodegradable ye-spunbond engalukwanga, imiba efana nesantya sempompo yokulinganisa, ubushushu obushushu obuqengqelekayo, kunye nobushushu obujikelezayo bunokuba nefuthe elibonakalayo kwiipropathi ezibonakalayo zelaphu le-spunbond elingalukwanga. Lungisa ngokweemfuno zabathengi ezinjengobunzima, ubukhulu, amandla okuqina, njl.

Impembelelo yesantya sempompo yokulinganisa

Ngokuseta isantya sempompo yokulinganisa iimitha ezahlukeneyo, iipropathi zefiber zefilaments ezilungisiweyo zefayibha ezilungiselelweyo, ezinje ngoxinaniso lomgca, idiameter yefiber, kunye nefiber fracture yamandla, zihlalutywa ukumisela isantya sempompo yokulinganisa esona siphezulu sokusebenza kwefilaments elungiselelwe ifayibha edibeneyo. Kwangaxeshanye, ngokuseta isantya sempompo yokulinganisa iimitha ezahlukeneyo ukuhlalutya izalathisi zokusebenza ezifana nobunzima, ubukhulu, kunye namandla okuqina kwelaphu elihlanganisiweyo le-spunbond nonwoven, esona santya siphezulu sempompo yokulinganisa sinokufunyanwa ngokudibanisa iipropathi zefayibha kunye neempawu ezingalukwanga zelaphu elihlanganisiweyo le-spunbond elingalukwanga.

Impembelelo yeqondo lokushisa elishushu

Ngokulungisa ezinye iiparameters zenkqubo yokulungiselela kunye nokubeka ii-mills ezahlukeneyo kunye namaqondo okushisa okutshisa okutshisayo, impembelelo yokushisa okutshisayo kwiipropati ze-filaments ezilungisiweyo ze-fiber filaments zifundwa kwaye zihlalutywe. Xa iqondo lokushisa lokuqiniswa kwe-hot rolling ye-rolling mill liphantsi kakhulu, i-fibers e-hot-rolled ayinakunyibilika ngokupheleleyo, okubangela iipateni ezingacacanga kunye nokuvakalelwa kwesandla esibi. Ukuthatha ulungiselelo biodegradable polylactic acid/additive/polypropylene composite spunbond ilaphu non-elukiweyo njengomzekelo, xa iqondo lobushushu eshushu rolling ukuqinisa ifikelela 70 ℃, imigca ifayibha edityanisiweyo icacile kwaye kukho ukuncamathela kancinane kumqulu, ngoko ke 70 ℃ iqondo lobushushu lifikelele kumda wokomeleza ongaphezulu.

Impembelelo yobushushu obujikelezayo

Iimpembelelo zamaqondo obushushu ahlukeneyo asontayo kwiipropathi zoxinaniso lwemisonto yefayibha edityanisiweyo, idiameter yefayibha, kunye nokomelela kwefayibha yokwaphuka, kunye neempawu zelaphu le-biodegradable polypropylene composite spunbond nonwoven, ngelixa kulungiswa ezinye iiparamitha zenkqubo yokulungiselela.

Inkqubo yokuhamba kwetekhnoloji yelaphu elidityanisiweyo lepolypropylene edibeneyo yespunbond engalukwanga

(1) Sika i-polylactic acid, i-polypropylene, kunye ne-maleic anhydride graft copolymer kwaye uzixube ngokwemilinganiselo efanelekileyo;

(2) Sebenzisa i-extruder yegranulation kunye nomatshini wokusonta ukusonta;

(3) Hlunga ngesihluzo sokunyibilika kwaye wenze umnatha phantsi kwentshukumo yempompo yokulinganisa, isomisi esivuthelayo, kunye nesantya esiphezulu sokuhamba komoya esolula;
