Yintoni iLaphu eliMeltblown | JINHAOCHENG

Yintoni ilaphu elinyibilikisiweyo?ilaphu elingalukwanga eliqhushumbisiweyoumenzi uJin Haocheng ukuze anizise, ​​umxholo ophambili ngolu hlobo lulandelayo:

Ilaphu elisekelwe kwi-polypropylene eqhushumbisiweyo elinyibilikisiweyo elinobubanzi befayibha obuyi-1 ukuya kwi-5 microns. Ii-voids ezininzi, ulwakhiwo oluthambileyo, ukumelana okuhle kokugoba. Olu lwakhiwo lukhethekileyo lwe-microfiber lwenza inani lefayibha kwindawo nganye kunye nommandla othile womphezulu linyuke.

Ukuze ilaphu elinyibilikisiweyo libe nokuhluzwa okuhle, ukhuselo, ubushushu kunye nokusebenza kakuhle kokufunxwa kweoyile. Lifanelekile kwizixhobo zokuhluza umoya kunye nolwelo, izixhobo zokufunxwa kobushushu, izixhobo zokufunxwa, izixhobo zemaski yobuso, izixhobo zokugcina ubushushu, izinto zokufunxwa kweoyile, iiwipes kunye nezinye iindawo.

Ububanzi bokusetyenziswa kwelaphu eliqhushumbisiweyo

Ilaphu lezonyango nelezempilo: ilokhwe yokusebenza, impahla yokukhusela, ilaphu lokusonga izibulali-ntsholongwane, iimaski, iinapukeni, iinapkin zabasetyhini, njl.

Ilaphu lokuhombisa ikhaya: ilaphu lodonga, ilaphu letafile, ishiti yebhedi, ilaphu lokugquma iibhedi, njl.njl.;

Ilaphu lempahla: ilaphu, ilaphu lokuncamathelisa, i-flocculant, umqhaphu wokubumba, zonke iintlobo zesikhumba esenziwe ngokwenziwa, njl.

Ilaphu lemizi-mveliso: izinto zokucoca, izinto zokukhusela, ibhegi yokupakisha yesamente, i-geotextile, ilaphu eligqunyiweyo, njl.

Ilaphu lezolimo: ilaphu lokukhusela izityalo, ilaphu lezithole, ilaphu lokunkcenkceshela, ikhethini yokukhusela, njl. 

Ezinye: umqhaphu ongaphakathi, izinto zokuthintela ubushushu, ifeli yokufunxa ioyile, isihluzi somsi, ibhegi yengxowa yeti, njl.

Yintoni umahluko phakathi kwelaphu elinyibilikisiweyo nelaphu elingalukwanga?

Ilaphu eliqhushumbisiweyo lenziwe kakhulu nge-polypropylene enobubanzi befayibha ukuya kuthi ga kwi-1 ~ 5 microns. Lo matshini uneendlela ezahlukeneyo zokuvula, ulwakhiwo oluthambileyo, ukusebenza kakuhle kokungagobi. I-Microfiber inesakhiwo esahlukileyo se-capillary, esongeza inani lefayibha kwindawo nganye kunye nommandla othile womphezulu.

Izinto zokucoca ziyi-melt-blown polypropylene microfibers enokusasazwa ngokungacwangciswanga kwe-bonding, imbonakalo emhlophe, igudileyo, i-0.5-1.0 soft fiber fiber degree yezinto, ukusasazwa okungacwangciswanga kwe-fiber fiber kunika amathuba amaninzi okubopha ngobushushu.

Ilaphu eliqhushumbisiweyo lisebenza kakuhle ekuhluzeni, ekukhuseleni, ekugqumeni nasekufunxeni ioyile. Lingasetyenziswa njengezixhobo zokucoca umoya nolwelo, izinto zokwahlukanisa, izinto zokufunxa, izinto zemaski, izinto zokugcina ubushushu, izinto zokufunxa ioyile kunye nelaphu lokusula.

Ngoko ke, izinto zokucoca igesi ezinyibilikisiweyo zinendawo enkulu ethile kunye ne-porosity ephezulu (≥75%). Phantsi kokusebenza kakuhle kokucoca ngoxinzelelo oluphezulu, imveliso inokumelana okuphantsi, ukusebenza kakuhle, amandla aphezulu othuli njl.njl.

Amalaphu angalukwanga ayakwazi ukumelana nokufuma, ayakwazi ukuphefumla, ayakwazi ukuguquguquka, alula, awatshi, kulula ukuwabola, awanobungozi, awakhuthazi, anemibala, angabizi, ayakwazi ukuphinda asetyenziswe njalo njalo. Olu vumbululo luthatha amasuntswana e-polypropylene (PP material) njengezinto ezikrwada, kwaye luhlala luveliswa ngokunyibilika kobushushu obuphezulu, ukutshiza, ukugawula kunye nokujikeleziswa okushushu.

Iimpawu zelaphu elingalukwanga:

Ilaphu elingalukwanga alinawo umphetho okanye uboya, kulula kakhulu ukulisika nokuthunga, lilula, linobume obulula, njengabathandi bezandla.

Ngenxa yokuba lilaphu elinokwenziwa ngaphandle kokusonta, lifuna kuphela ukuhlalutya nokuJolisa okanye ukucwangcisa ngokungacwangciswanga i-short okanye i-filament yelaphu ukuze lenze isakhiwo se-fiber net, lize lisebenzise iindlela zemveli zoomatshini, zokubopha ubushushu okanye zeekhemikhali ukuze liqiniswe.

Oku akwenziwa ngokuluka imisonto, kodwa ngokuyidibanisa ngqo imisonto, ukuze xa ufumana igama lokunamathela kwisambatho, ufumanise ukuba ayinakutsalwa kwintambo. Ilaphu elingalukwanga lidlule kumgaqo wendabuko welaphu, ngenkqubo emfutshane, isantya sokuvelisa ngokukhawuleza, imveliso ephezulu, ixabiso eliphantsi, ukusetyenziswa ngokubanzi, izinto eziluhlaza njalo njalo.

Ubudlelwane phakathi kwamalaphu angalukwanga kunye namalaphu asontiweyo:

Ii-nonwovens ezisontiweyo kunye neemveliso zazo ezincedisayo. Uthotho lweenkqubo zemveliso ye-nonwovens zimelwe zii-nonwovens ezisontiweyo, ii-nonwovens ezinyibilikisiweyo, ii-nonwovens ezisongiweyo ezishushu kunye nee-nonwovens ezisontiweyo. Iimpawu zayo zezi zilandelayo: ii-nonwovens ezisontiweyo yindlela yemveliso, kwaye uninzi lwabafundi kwimarike basebenzisa ii-nonwovens ezisontiweyo ukuvelisa ii-nonwovens.

Ilaphu elingalukwanga ngokwendlela elibunjwe ngayo, i-polyester, i-polypropylene, i-nylon, i-polyurethane, i-acrylic acid njl. Izinto ezahlukeneyo zineendlela ezahlukeneyo zelaphu elingalukwanga. Amalaphu angalukwanga adla ngokubhekisa kwi-polyester binders kunye ne-polypropylene binders. Iintlobo zamalaphu amabini ziyafana kakhulu kwaye zinokubonwa ngobushushu obuphezulu.

Ilaphu elingalukwanga libhekisa kwilaphu lokugqibela elingalukwanga elenziwe ngokusetyenziswa ngokuthe ngqo kwephepha lepolymer, ifilament emfutshane okanye ukufakwa kwefayibha yefilament okanye ukucutshungulwa koomatshini, ukusontwa, ukuncitshiswa okanye ukuqiniswa okujijekileyo okushushu.

Iimveliso ezintsha zefayibha ezithambileyo neziphefumlayo kunye nesakhiwo esithe tyaba, azivelisi iingenelo ezithambileyo, eziqinileyo, ezihlala ixesha elide, ezithambileyo, ezifana nezesilika, zenziwe ngezinto eziphuculweyo, kodwa umqhaphu nawo unomtsalane, xa uthelekiswa neengxowa ezingalukwanga zomqhaphu ezilula ukuzenza, kwaye zingabizi kakhulu.

Iingenelo:

Ubunzima obulula: i-polypropylene synthetic resin njengomxholo ophambili wemveliso yezinto ezikrwada, ubunzima obuthile be-0.9 kuphela, isithathu kwisihlanu sekotoni yaseTshayina kuphela, enoburhabaxa, imvakalelo entle.

Yenziwe ngefayibha ecolekileyo (2-3D) eshushu yokunyibilika...Imveliso egqityiweyo inobuthambile obuphakathi kunye nentuthuzelo.

Igxotha amanzi, iyakwazi ukuphefumla: itshiphu yepolypropylene engafunxiyo, akukho kufuma, icala lamanzi ligqityiwe, linemingxuma, umoya ungena kakuhle, kulula ukuyigcina ilaphu elomileyo 100 iintlobo ze-% fiber, kulula ukuyihlamba.

Ayinatyhefu, ayicaphukisi: imveliso ingahambelana ngakumbi nezinto eziluhlaza ze-FDA zezinga lokutya zokwenziwa, ayinazo ezinye izithako zeekhemikhali zabafundi, ukusebenza kwayo kuzinzile, ayinatyhefu, ayinavumba, ayikruquli ulusu.

Izinto ezilwa neentsholongwane kunye neekhemikhali: i-polypropylene yinto ekrwada yekhemikhali, ayizizo ezibangela iintsholongwane, inokwahlula ubukho beentsholongwane kunye nokukhukuliseka kwezinambuzane kulwelo; Iimveliso ezilwa neentsholongwane, ukubola kwe-alkali, kunye neemveliso ezigqityiweyo azichaphazeli amandla okukhukuliseka.

Iimpawu zokulwa neentsholongwane: ukutsalwa ngamanzi, ukungunda, iintsholongwane kunye nezinambuzane kwaye ulwelo lunokwahlula ubukho bokukhukuliseka, ukubola kwemveliso.

Iipropati ezilungileyo zomzimba: ezenziwe nge-polypropylene spinning zinokusasazwa ngqo kwinethiwekhi yesiphumo sokubopha ngobushushu, imveliso inamandla angcono kuneemveliso zefayibha eziqhelekileyo, amandla awanalo icala, amandla esakhiwo athe nkqo nathe tye kunye nezinye izinto ezifanayo.

Ngokwembono yokhuseleko lokusingqongileyo: uninzi lwamalaphu angalukwanga enziwe nge-polypropylene, ngelixa iingxowa zeplastiki zenziwe nge-polyethylene. Nangona amagama azo afana, ezi zinto zimbini zinezakhiwo zeekhemikhali ezahlukeneyo kakhulu. Ulwakhiwo lweekhemikhali lwe-polypropylene luzinzile kakhulu kwaye kunzima ukuluhluza, ngoko ke kuthatha iminyaka engama-300 ukuba iingxowa zeplastiki zihluzeke. Kwaye ulwakhiwo lweekhemikhali lwe-polypropylene alunamandla, uthotho lweemolekyuli kulula ukuluqhekeza, ngoko ke kuyimfuneko ukwenza ukuwohloka okusebenzayo. Iingxowa ezingalukwanga ziqhubekela kumjikelo olandelayo ngendlela engeyiyo ityhefu kwaye zinokubola ngokupheleleyo kwiintsuku ezingama-90. Ngaphezu koko, iingxowa zokuthenga ezingalukwanga zingaphinda zisetyenziswe ngaphezulu kwezihlandlo ezili-10, kwaye ungcoliseko lokusingqongileyo emva kwenkunkuma yi-10% kuphela yeengxowa zeplastiki.

Iingxaki:

Amandla nokuqina okungekho ngqiqweni xa kuthelekiswa namalaphu alukiweyo.

Ayinakucocwa njengezinye ilaphu.

Ekubeni iifayibha zicwangciswe kwicala elithile, kulula ukuziqhekeza ukusuka kwi-engile ekunene, njl. Ngoko ke, ingqwalasela yokuphucula indlela yokuvelisa kukuphucula amandla okumelana nokuqhekeka.

Eli nqaku lingasentla licwangciswe kwaye lipapashwe ngabathengisi abangolukiweyo abanyibilikisiweyo. Ukuba awuqondi, wamkelekile ukuba uqhagamshelane nathi!
