Zithini iimpawu zeizinto ezingelukiweyo eziqhumayo ezinyibilikisiweyoNamhlanje, makhe sijonge oku kulandelayo. Ndiyathemba ukuba kuya kuba luncedo kuwe.
Iimpawu zokusebenza kwe-Melt blown Nonwovens
Izinto ezingalukwanga ezinyibilikisiweyo luhlobo oluthileizinto ezingezizo ezolukiweyoenesakhiwo sefayibha esicolekileyo kakhulu, esilungiswa ngenkqubo yokunyibilika kunye nokutsalwa komoya oshushu ophantsi koxinzelelo oluphezulu. Ii-nonwovens eziqhushumbisiweyo ezinyibilikayo ziye zaba zizixhobo zokucoca ezibaluleke ngakumbi ngenxa yokusebenza kwazo okugqwesileyo kokuhluza, isivuno esiphezulu kunye netekhnoloji yokucubungula elula. Izinto zokucoca ezilungiselelwe ngendlela yokunyibilika zineengenelo zokulungiswa kwefayibha, isakhiwo esimdaka nesithambileyo esinemilinganiselo emithathu kunye nokusebenza kakuhle kokuhluza. Idlala indima ebalulekileyo kwezonyango nakwimpilo, kushishino lweekhemikhali zokutya, kwii-microelectronics, kukhuseleko lokusingqongileyo nakwezinye iindawo.
Phantsi kwengcamango yokuba ezinye iiparameter zenkqubo azitshintshi, uxinzelelo lomoya oshushu lunempembelelo enkulu kwiimpawu ze-nonwovens. Ngokunyuka koxinzelelo lomoya oshushu, ukungena komoya kwemveliso kuncipha kancinci, oko kukuthi, ukungena komoya kuncipha. Emva kokuba ifayibha ikhutshiwe kumngxuma we-spinneret, yolulwa ngakumbi kwaye icocwe phantsi kokutsalwa komoya oshushu. Uxinzelelo lomoya oshushu oluphezulu luluncedo ngakumbi ekuphuculeni ifayibha. Ke ngoko, ngokwanda koxinzelelo lomoya oshushu, ububanzi befayibha buba mncinci. Xa iifayibha ezininzi zixinene kwaye zipakishwe ngokungacwangciswanga kwizixhobo ze-mesh ukuze zenze ii-nonwovens ezinyibilikisiweyo, okukhona iifayibha zincinci, kokukhona kulula ukwenza ii-nonwovens ezine-porosity ephezulu kunye nommandla ophezulu womphezulu, kwaye ububanzi be-pore obunjwe phakathi kweefayibha buncinci. ke ngoko, ukusebenza kakuhle kwe-interception kwamasuntswana nako kuphezulu.
Phantsi kwengcamango yokuba ezinye iiparameter zenkqubo azitshintshi, uxinzelelo lomoya oshushu lunempembelelo enkulu kwiimpawu ze-nonwovens. Njengoko ubushushu bomoya oshushu bunyuka kancinci kancinci.
Ukungena komoya kwemveliso kuncipha kancinci kancinci, oko kukuthi, ukungena komoya kuncipha. Emva kokuba ifayibha ikhutshiwe kumngxuma we-spinneret, iphuculwa ngakumbi phantsi kokutsalwa komoya oshushu. Ubushushu bomoya oshushu obuphezulu bunokubonelela ngobushushu obuninzi, obucothisa inkqubo yokupholisa yefayibha kwaye bunceda ngakumbi ekutsaleni nasekuphuculeni ifayibha. Ke ngoko, ngokunyuka kancinci kobushushu bomoya oshushu, ububanzi befayibha buba mncinci. Xa iifayibha ezingenakubalwa zibekwe ngokungacwangciswanga kwaye zibotshelelwe kwizixhobo ze-mesh ukuze zenze ii-nonwovens ezinyibilikisiweyo, okukhona iifayibha zincinci, kokukhona kunokwenzeka ukuba zenze ii-nonwovens ezine-porosity ephezulu kunye nesakhiwo esiphezulu somphezulu othile, kwaye ubungakanani be-pore phakathi kweefayibha buncinci. ke ngoko, ukusebenza kakuhle kwe-interception yamasuntswana nako kuphezulu.
Xa ii-nonwovens eziqhushumbiswe yi-PET melt zilungiswa ngendlela yokuqhushumbiswa yi-melt, uxinzelelo lomoya oshushu, ubushushu bomoya oshushu kunye ne-resin viscosity zinefuthe elikhulu kwiimpawu ze-nonwovens eziqhushumbiswe yi-PET melt. Ukunyusa uxinzelelo lomoya oshushu kunye nobushushu kunye nokunciphisa i-viscosity ye-PET resin kuluncedo ekwakhiweni kwesakhiwo sefayibha enobubanzi obuncinci kwaye kuphuculwe ukusebenza kakuhle kokubanjwa kwamasuntswana.
Oku kungentla kukwazisa ngeempawu zee-nonwovens eziphehluzeliswe yi-melt blown. Ukuba ufuna ukwazi okungakumbi ngee-nonwovens eziphehluzeliswe yi-melt blown, nceda unxibelelane nathi.
