yintoni impahla ye-spunbond

Zininzi iindidi zamalaphu angalukwanga, kunye nelaphu elingalukwanga le-spunbond yenye yazo. Izinto eziphambili ze-spunbond zelaphu ezingalukwanga ziyi-polyester kunye ne-polypropylene, enamandla amakhulu kunye nokuchasana kakuhle kobushushu obuphezulu. Apha ngezantsi, umboniso welaphu elingalukwanga uya kukwazisa ukuba yintoni ilaphu elingalukwanga eliyi spunbond? yintoni impahla yespunbond? Makhe sijonge kunye.

Yintoni iindlela ye-spunbond

Isizathu esibalulekileyo sokuphuhliswa kwayo ngokukhawuleza kukuba isebenzisa iipolima zokwenziwa njengezinto eziluhlaza. Le ndlela isebenzisa umgaqo we-chemical fiber spinning ukuya kwi-filament eqhubekayo ngexesha lenkqubo ye-polymer spinning, ethi emva koko itshizwe kwiwebhu kwaye idibaniswe ngokuthe ngqo ukuvelisa amalaphu angalukwanga. Indlela yokuvelisa ilula kakhulu kwaye ikhawuleza. Xa kuthelekiswa neteknoloji eyomileyo yokucubungula ilaphu elilukiweyo, liphelisa uthotho lweenkqubo ezidinayo eziphakathi ezifana ne-fiber curling, ukusika, ukupakisha, ukuthutha, ukuxuba, kunye nokudibanisa Eyona mpembelelo ibalulekileyo yemveliso yobuninzi kukwenza iimveliso ze-spunbond zibe namandla aphezulu, ixabiso eliphantsi, kunye nomgangatho ozinzile. Ukolulwa kwendlela ye-spunbond yeyona ngxaki ingundoqo yobugcisa bokufumana imicu ye-denier emihle kunye nemathiriyeli ephezulu yamandla angeyo-woven, kwaye ngoku eyona ndlela iphambili bubuchwephesha bokuhamba komoya. Ukuze kuphuculwe ngakumbi idrafti yokuhamba komoya yeentsinga ze-spunbond, ukukhutshwa okuphezulu komgangatho wokujikeleza komngxuma omnye, uyilo lwemingxuma ephezulu yoxinaniso lwe-spinneret, kunye nefuthe labo kwimveliso kunye nomgangatho wezinto ezingalukwanga, sifunda uyilo lwetshaneli eyidrafti edibanisa uxinzelelo olulungileyo kunye noxinzelelo olubi, kunye nefuthe le-electrostatic spinner kwisantya sokujikeleza, ukujikeleza kwewebhu kunye nobubanzi obufanayo. Olu luhlobo olukhethekileyo lwezixhobo ze-spunbond ezenzelwe ushishino, Omnye wemisebenzi ephambili yezixhobo ze-spunbond ezihambelanayo ezimbini.

yintoni impahla ye-spunbond

Iimathiriyeli ekrwada yeamalaphu e-spunbond angalukwangaikakhulu zibandakanya iintsinga zeselulosi kunye neentsinga zokwenziwa, ezenziwa ngenkqubo yespunbond. Inesandla esilungileyo sokuziva, ukuphefumla, kunye nokumelana nokunxiba, kwaye isetyenziswa kakhulu kwiinkalo ezahlukeneyo. Inkqubo yokwenziwa kwelaphu le-spunbond elingalukwanga lilula, liyonga iindleko, kwaye linethemba elibanzi lemarike. Kuyathenjwa ukuba kuya kubakho izinto ezintsha ezintsha kunye nophuhliso kwixesha elizayo, ukuze ilaphu elingalukwanga le-spunbond lidlale indima enkulu kwiinkalo ezahlukeneyo.

I-cellulose fiber

Ifayibha yeCellulose yenye yezinto ezibalulekileyo zokwenziwa kwamalaphu angalukwanga e-spunbond. I-Cellulose yikhompawundi yendalo yendalo ekhoyo ngokubanzi kwiindonga zeeseli zesityalo. Iintsinga ezininzi zezityalo, ezinjengomqhaphu, ilinen, ihemp, njl., zineselulosi eninzi. Ezi zityalo zifumana unyango oluninzi, olufana nokuxobula, ukuthanjiswa, nokubilisa, ukukhupha i-cellulose kwizityalo. Emva koko, ngenkqubo ye-spunbond, iintsinga zeselulosi zoluliwe kwaye zijongiswe ukuze zenze ilaphu le-spunbond elingalukwanga. Iintsinga zeCellulose zinokuthamba okuhle kunye nokuphefumla, ukwenza amalaphu e-spunbond angalukwanga abe nesandla esilungileyo kunye nokuphefumla.

Iintsinga zokwenziwa

Iintsinga zokwenziwa zezinye izinto ezidla ngokusetyenziswa ekrwada kumalaphu e-spunbond angalukwanga. Iifiber zokwenziwa ziifiber ezenziwe ngokwenziwa kokwenziwa okanye ukuguqulwa kweekhemikhali, njengemicu yepolyester, imicu yenylon, njl njl. Kwinkqubo yokwenziwa kwamalaphu e-spunbond angalukwanga, iintsinga zokwenziwa zihlala zixutywa neentsinga zeselulosi ukuphucula ukomelela kunye nokumelana nokunxiba kwamalaphu angalukwanga e-spunbond.

Yintoni ilaphu le-spunbond elingalukwanga?

Ilaphu elingaphothiweyo elingalukwanga, ikakhulu elenziwe ngepolyester kunye ne-polypropylene, linamandla aphezulu kunye nokumelana nobushushu obuphezulu. Ilaphu eliphothiweyo elingengomlukwanga likhupha ngaphandle kwaye linwebe iipholima ukuze zenze imicu eqhubekayo, ethi emva koko ibekwe kwiwebhu. Iwebhu ke iyazibophelela, ibotshwe ngokwe thermally, ibotshwe ngokwekhemikhali, okanye iqiniswe ngoomatshini ukuze iguquke ibe lilaphu elingalukwanga.

Ukukhethwa kwemathiriyeli ekrwada

Izinto ezisetyenziswa kumgca wemveliso zihambelana nokuma kwemarike kunye nenjongo yemveliso. Xa uvelisa iimveliso zeemarike eziphantsi, ngenxa yeemfuno eziphantsi zezinto eziphathekayo, ukuze kuncitshiswe iindleko zemveliso, izinto eziphantsi zomgangatho zingakhethwa. Okuchaseneyo nako kuyinyaniso.

Uninzi lwemigca yemveliso ye-spunbond nonwoven zisebenzisa iitshiphusi zepolypropylene (PP) zegranular njengemathiriyeli ekrwada, kodwa kukwakho nemigca emincinci yemveliso esebenzisa umgubo wePP, kunye neminye imigca yemveliso esebenzisa imathiriyeli ekrwada yepolypropylene. Ukongeza kwimathiriyeli ekrwada ekrwada, iintambo zemveliso ezingalukwanga ezinyibilikayo zinokusebenzisa imathiriyeli ekrwada engqukuva.

Ixabiso le-slicing lihambelana ngqo nobukhulu bexabiso layo le-MFI, ngokubanzi ixabiso elikhulu le-MFl, ixabiso eliphezulu. Ke ngoko, kuyafuneka ukuba kuqwalaselwe ngokubanzi inkqubo yemveliso, iimpawu zezixhobo, ukusetyenziswa kwemveliso, ixabiso lentengiso yemveliso, ixabiso lemveliso, kunye nezinye izinto zokukhetha izixhobo ezisetyenziswayo.
