Iindlela ezininzi zokwenza ilaphu le-hydrophilic Nonwoven

IHydrophilic yindlela yonyango eqhelekileyo yamalaphu angalukwanga. Ngokuqhelekileyo, amalaphu angalukwanga ayawagxotha amanzi. Ngokwemfuno, abavelisi benza unyango lwangaphambili okanye emva konyango kumalaphu angaphothiweyo, kwaye ezi zonyango zimbini zichaphazela ngqo isiphumo se-hydrophilic. Namhlanje mandikuzisele umahluko phakathi konyango lwangaphambili kunye nasemva kokunyangwa kwamalaphu angalukwanga e-hydrophilic. Ndiyathemba ukuba ingakunceda!

Okokuqala, amalaphu angalukwanga agxotha amanzi, amalaphu angalukwanga e-hydrophilic kunye namalaphu angalukwanga achasene namanzi achaseneyo. Ngenxa yokuba ilaphu elingalukwanga ngokwalo aliyiyo i-hydrophilic, kuyimfuneko ukongeza i-hydrophilic masterbatch okanye ukongeza i-oyile ye-hydrophilic ukuphucula umlinganiselo we-hydrophilic welaphu elingaphothiweyo le-hydrophilic, oko kukuthi ukuphucula ukusebenza kwe-hydrophilic.

Ilaphu le-Hydrophilic non-woven libonakaliswe ngokukwazi ukufunxa amanzi, oko kukuthi, umlinganiselo we-hydrophilic, isantya se-hydrophilic, amaxesha e-hydrophilic, ixesha le-hydrophilic yokuqinisekisa kunye namaxesha. Ukuze kuphuculwe i-hydrophilicity yamalaphu angalukwanga, ngokuqhelekileyo kukuphucula ukumanzi komphezulu ukufezekisa injongo ye-hydrophilicity. Okwangoku, iindlela zokwenza amalaphu e-hydrophilic angalukwanga ikakhulu ngokuguqulwa komzimba kunye nokuguqulwa kweekhemikhali: ukuguqulwa kokudibanisa (okt phambi kokusonta) kunye nokuguqulwa komphezulu (okt emva kokusonta).

1. Ukuguqulwa kokudibanisa (ukuguqulwa ngaphambi kokujikeleza)

Ngokwexesha elongezelelweyo elongezelelweyo lezongezo ezilungisiweyo, zinokwahlulwa ngendlela ye-masterbatch, indlela epheleleyo yegranulation kunye nendlela yokutofa ngaphambi kokusonta.

1. Indlela ye-masterbatch eqhelekileyo

Le yindlela ebalulekileyo yokuba abavelisi abangalukwanga bavelise amalaphu e-hydrophilic angalukwanga. I-Hydrophilic masterbatch yenziwe ngokongezwa kwe-hydrophilic eqhelekileyo ngumvelisi we-masterbatch, emva koko yadityaniswa ne-PP ukunyibilikisa ilaphu elijikelezayo, elibizwa ngokuba yi-hydrophilic engeyolukiweyo ilaphu.

Izibonelelo: imveliso elula, akukho mfuneko yokongeza nayiphi na isixhobo, kwaye ifanelekile kwimveliso encinci yebhetshi. Ukongeza, ukuzingisa kwayo kwe-hydrophilic kunamandla.

2. Igranulation iyonke

Amasuntswana e-Hydrophilic PP aye alungiswa nge-screw extrusion granulation, kwaye emva koko anyibilike ephothiweyo kwilaphu.

inzuzo; Ukuqhubekeka okuhle, isiphumo esomeleleyo, ilaphu linokusetyenziswa ngokuphindaphindiweyo.

3. Isitofu phambi kokusonta

I-polymer ye-hydrophilic yongezwa ngokuthe ngqo kwi-screw engundoqo yelaphu elingalukwanga kwaye ixutywe ne-PP inyibilika ukujikeleza ngokuthe ngqo.

Izinto eziluncedo: isiphumo esihlala ixesha elide, ilaphu lingasetyenziswa ngokuphindaphindiweyo

2.Ukugqitywa kwe-hydrophilic (ukuguqulwa emva kokujikeleza)

Ukugqitywa kwe-Hydrophilic yindlela elula, esebenzayo kunye nexabiso eliphantsi ukwenza amalaphu e-hydrophilic angalukwanga. Eyona nkqubo yethekhinoloji yile ilandelayo:

On line spunbonded amalaphu ashushu aqengqelekayo non-elukiweyo -- roll ukutyabeka okanye ukutshiza agent hydrophilic -- infrared okanye hot air dryer -- winder -- hydrophilic ukugqiba non-elukiweyo inwebu.

Izinto eziluncedo: akukho ngxaki ye-spinnability, isiphumo esikhawulezayo se-hydrophilic, ukusebenza kakuhle okuphezulu kunye nexabiso eliphantsi lelaphu elingalukwanga, eliyi-1 / 2-1 / 3 yeendleko zendlela ye-masterbatch eqhelekileyo. Ifanelekile kwimveliso yobuninzi.
