Zeziphi izalathisi zokusebenza ze-meltblown& spunbonded nonwoven fabric

Zeziphi izalathisi zentsebenzo yelaphu elinyibilikayo kunye eliphothiweyo elingaphothiweyo?

1.Ukufana

Ukufana kubonakaliswa yi-discrete coefficient ye-CV yexabiso lexabiso lobungakanani, elibonisa ukusabalalisa okungalinganiyo kwe-fiber mesh (engqindilili kunye nencinci) yemveliso. Ixabiso elikhulu le-CV, libi kakhulu umgangatho wemveliso. Ngokubanzi, ubukhulu bexabiso lobungakanani bemveliso, lincinci ixabiso leCV. Ixabiso le-CV liku-“%”. Ubungakanani, obuchazwa njengobunzima (umgangatho) wemveliso kwindawo nganye yeyunithi, kunye neyunithi yomthetho yokulinganisa eTshayina yi g / m2 okanye g / m2

2.Onamandla

Amandla abhekisela kumandla aphezulu afunekayo ukuphula umkhiqizo ngexesha lokuvavanya amandla (i-tensile), kwaye iyunithi ngu-N. Ubukhulu obukhulu, bungcono umgangatho wemveliso. Amandla awahambelani kuphela nobungakanani bobungakanani bemveliso (ubungakanani obukhulu, amandla amakhulu), kodwa anxulumene nolwalathiso loxinzelelo lwemveliso.

Isalathiso semveliso ngokuqhelekileyo sahlulahlulwe saba ziindidi ezimbini: indlela yokusebenza yomgca wemveliso (ebizwa ngokuba yi-MD) kunye nesalathiso esithe tye (isalathiso se-perpendicular ukuya kwindlela eqhuba ngayo umgca wemveliso ongasontiyo, obizwa ngokuba yiCD). Ngeendlela ezahlukeneyo zokubeka i-mesh ezisetyenziswa kumgca wemveliso, i-anisotropic phenomenon ikhona kwiimveliso eziqhelekileyo. Umzekelo, amandla olwalathiso lwe-MD yeemveliso ezinokubekwa kwe-mesh longitudinal ziya kuba zikhulu, kwaye amandla e-MD yeminye imigca yemveliso anokuba kabini okanye nangaphezulu kuneCD. Amandla emveliso efanayo nawo ahluke kwiindlela ezahlukeneyo. Kwisicelo esisebenzayo, kunethemba lokuba amandla obude kunye no-transverse asondele omnye komnye, ukwenzela ukuba imveliso isotropic.

3.Ukwandiswa ngexesha lekhefu

Ukwandiswa ngexesha lekhefu kubhekiselele kumlinganiselo wenxalenye yokwandiswa kwemveliso ukuya kubude bokuqala besampulu ngexesha lovavanyo lokuqina. Iyunithi yobude ngexesha lekhefu ngu "%". Xa umgangatho wemveliso ulungile kwaye i-fiber itsalwe ngokupheleleyo, ubude bekhefu bungaphantsi kwe-100%; Ubude bobude belaphu elivuthelweyo buncinci, bungaphantsi kwama-50%.

Ngenxa yokuba amandla okuqhawula imveliso ahluke kumacala amabini, ukunyuka kwe-MD kunye ne-CD kwahlukile. Kwiinkalo ezininzi zesicelo, i-elongation encinci kwi-break, ingcono, kwaye i-elongation ngexesha lekhefu kwiindlela ezahlukeneyo kufuneka isondele ngokusemandleni.

4.Ubunengenelo

I-Permeability isalathiso esibonisa isakhono se-hydrophilic semveliso kwi-spinning kunye nokunyibilika kwezinto zococeko, ezibonisa amandla olwelo ukudlula kwimveliso (ngokukhawuleza kunye nokucotha). I-permeability inokwahlulwa ibe yi-permeability yexesha elinye kunye ne-multiple permeability. Ixesha lifutshane, lingcono.

5.Uxinzelelo lweHydrostatic (HSH)

Kwiimathiriyeli zococeko, uxinzelelo lwe-hydrostatic luphawu olubonisa umthamo womqobo weemveliso, obonisa ukukwazi kweemveliso ukuthwala uxinzelelo oluthile (uxinzelelo lwe-hydrostatic) ulwelo. Iyunithi yokulinganisa "ikholamu yamanzi mm" okanye "ikholamu yamanzi ye-cm", ngamanye amaxesha ibonakaliswa yi-PA (PA), ixabiso elikhulu, lingcono. Uxinzelelo lwe-hydrostatic ye-15 g / m2 izinto zococeko kufuneka zibe malunga ne-150 mm ikholamu yamanzi. Kuhlobo olufanayo lwemveliso, okukhona umlinganiselo omkhulu, uphezulu uxinzelelo lwe-hydrostatic.

6.Ukungena komoya

Ukungena komoya sisalathiso xa ii-nonwovens zisetyenziswa njengezinto zokuhluza igesi. Ibonisa ukunyanzeliswa kwegesi kumacala omabini emveliso phantsi kwemeko yokuhluka koxinzelelo oluchaziweyo. Ibonakaliswa ngokungena kwerhasi ngexesha leyunithi. Okukhona uphezulu ukungeneka komoya, kokukhona igesi idlula lula kwilaphu elingalukwanga.

7.Antistatic

Ipropati ye-Antistatic yisalathiso samandla angatshintshiyo angatshintshiyo wokujikeleza kunye neemveliso ezinyibilikayo. Okukhona ukusebenza ngcono kwe-antistatic, i-electrostatic encinci inokuqokelelana kwimveliso, kokukhona ukhuseleko lwemveliso luphezulu. Ukusebenza kwe-antistatic kuvame ukubonakaliswa ngokumelana nomthamo womphezulu, ngo-ohm(Ω)。 Okuncinci ukuxhathisa komphezulu, kokukhona usetyenziso lwe-antistatic. Ngamanye amaxesha, i-static half-life (s), okanye isixa sentlawulo ephezulu sisetyenziselwa ukubonisa ukusebenza kwe-antistatic yemveliso. Ubufutshane besiqingatha sobomi okanye intlawulo engaphantsi komhlaba, ingcono ukusebenza kwe-antistatic.
