Yintoni enyibilikayo elilaphu elingaphothiweyo

Yintoni enyibilikayo elilaphu elingalukwanga elivuthelweyo

Ilaphu elingalukwanga elivuthelweyo luhlobo olutsha lwemathiriyeli yelaphu elenziwe ngemathiriyeli yepolymer ephezulu ngeenkqubo ezinje ngokulungiswa kwemathiriyeli ekrwada, ukunyibilika okunobushushu obuphezulu, ukubumba ukutshiza, ukupholisa kunye nokuqiniswa. Xa kuthelekiswa nenaliti yemveli ngenqindi amalaphu non-elukiweyo, amalaphu zinyibilike avuthelwe non-elukiweyo abe ecikizekileyo kwaye ngaphezulu iyunifomu isakhiwo ifayibha, kunye nokuphefumla ezithile kunye nokumelana namanzi, ibenza ulwalathiso uphuhliso ebalulekileyo kwintsimi impahla elukiweyo.

Iimpawu zokunyibilika kwelaphu elingalukwanga elivuthelweyo

1. Ukusebenza kakuhle kokucoca, okunokuthintela ngokufanelekileyo ukusasazeka kwezinto ezinobungozi ezifana neengqungquthela, ibhaktheriya, iintsholongwane, njl.

2. Ithambile kwaye ikhululekile, ikwazi ukuphefumla kakuhle, ikhululekile ukunxiba, kwaye akukho kusabela komzimba;

3. Nxiba i-resistant, i-waterproof kunye ne-oyile yokumelana, kunye nobomi obude benkonzo kunye nokuqina okugqwesileyo;

4. Ukucutshungulwa ngokulula, okukwazi ukusika, ukuthunga, ukucinezela okutshisayo, i-laminating kunye nolunye unyango ngokweemfuno ezahlukeneyo.

Ukusetyenziswa kwelaphu elingalukwanga elivuthelweyo

Ilaphu elingalukwanga elinyibilikayo linoluhlu olubanzi lwethemba lokusetyenziswa, kwaye liye laphononongwa kwimimandla efana nokhathalelo lwempilo, ucoceko, kunye nefenitshala yasekhaya. Ezona ndawo zezicelo zezi zilandelayo:

1. Unyango kunye neMpilo: Ilaphu elingalukwanga elinyibilikayo lisetyenziswa kakhulu ekuvelisweni kwezixhobo ezikhuselayo ezinje ngeemaski, iigawuni zotyando, kunye neegawuni zokuzihlukanisa, ezinokwahlula ngokufanelekileyo iintsholongwane kunye neentsholongwane, ziqinisekisa ukhuseleko lwabasebenzi bezonyango kunye nezigulana.

2. Impahla yasekhaya: Ilaphu elinyibilikayo elingelukwanga elivuthelweyo lisetyenziselwa ukwenza iimfuno zemihla ngemihla ezifana nezisusi ezimanzi, izicoci zobuso, kunye neempahla zokuhlamba ezinokufakwa kakuhle kwamanzi, ukuxhathisa kwamanzi, kwaye akukho lula ukulahla iinwele, ukuphucula amava omsebenzisi.

3. Izinto zokucoca: Ilaphu elingalukwanga elivuthelweyo linokwenziwa libe yimpahla yokucoca umoya, amanzi, neoyile, enokususa ngokufanelekileyo amasuntswana emoyeni kwaye inciphise ukukhutshwa kongcoliseko. Isenokusetyenziswa nakwiindawo ezifana nokucoca ngoomatshini kunye nokucoca amanzi okusela.

Ilaphu elingalukwanga elivuthelweyo liyinto elungileyo yokugquma

Ilaphu le-Melt elivuthelweyo le-nonwoven linendawo enkulu yendawo ethile kunye ne-voids encinci (ubungakanani bepore ≤ 20) μ m) I-porosity ephezulu (≥ 75%) kunye nezinye iimpawu. Ukuba i-avareji yedayamitha yi-3 μ Indawo ethile yomphezulu wemicu yelaphu enyibilikayo evuthelweyo, elingana ne-avareji yoxinaniso lwefayibha ye-0.0638 dtex (enobukhulu be-fiber eyi-0.058 denier), ifikelela kwi-14617 cm2/g, ngelixa i-avareji ye-avareji yi-15.3 μ Indawo ethile ye-fiber enomndilili we-avareji ye-nonwoven fibers Ubuninzi be-1.65 dtex (kunye nobukhulu befiber ye-1.5), yi-2883 cm2 / g kuphela.

Ngenxa ye-thermal conductivity encinci yomoya xa kuthelekiswa neentsinga eziqhelekileyo, umoya okwimibhobho yelaphu elingaphothiweyo elinyibilikayo linciphisa ukuhanjiswa kwalo kwe-thermal. Ilahleko yobushushu esasazwa ngefiber imathiriyeli yelaphu elinyibilikayo elivuthelweyo elingaphothiweyo lincinci, kwaye umaleko womoya omileyo kumphezulu weentsinga ezingenakubalwa ze-ultrafine zithintela ukutshintshiselana kobushushu okubangelwa kukuhamba komoya, kuyenza ibe nefuthe elihle lokugquma kunye neziphumo zokufudumala.

I-Polypropylene (PP) ifayibha luhlobo lwefiber ekhoyo ekhoyo ene-conductivity ephantsi kakhulu ye-thermal. I-melt ivuthelwe i-thermal insulation floc eyenziwe nge-PP ifayibha emva kokuba unyango olukhethekileyo lunokusebenza kokufakelwa kwe-thermal amaxesha angama-1.5 angaphantsi kunye namaxesha angama-15 e-cotton yokufakelwa kwe-thermal eqhelekileyo. Ngokukodwa ezifanelekileyo ukwenza iimpahla zokushushuluza, iimpahla zokukhwela intaba, iibhedi, iingxowa zokulala, iimpahla zangaphantsi ezishushu, iiglavu, izihlangu, njl.

Indlela yokuphucula ukusebenza kakuhle kokucoca ilaphu elingalukwanga elivuthelweyo

Ilaphu elivuthelweyo elingalukwanga, njengeyona nto iphambili yeemaski zonyango, ukusebenza kakuhle kokucoca kwayo kuchaphazela ngokuthe ngqo isiphumo sokhuselo semaski. Zininzi izinto ezichaphazela ukusebenza kohluzo lwamalaphu angalukwanga anyibilikayo, anje nge-fiber linear density, i-fiber mesh structure, ubukhulu, kunye noxinaniso. Njengesixhobo sokucoca umoya kwiimaski, ukuba izinto zixinene kakhulu, iipores zincinci kakhulu, kwaye ukumelana nokuphefumla kuphezulu kakhulu, umsebenzisi akakwazi ukuphefumla umoya kakuhle, kwaye imaski iphulukana nexabiso layo lokusetyenziswa. Oku kufuna ukuba izixhobo zokucoca zingaphuculi kuphela ukusebenza kwazo kakuhle, kodwa zinciphisa ukuxhathisa ukuphefumla, nto leyo ephikisanayo phakathi kokumelana nokuphefumla kunye nokusebenza kakuhle kokucoca. Inkqubo yonyango ye-electret ye-electret yindlela efanelekileyo yokusombulula ukuchasana phakathi kokumelana nokuphefumla kunye nokusebenza kakuhle kokucoca.

Umqobo womatshini

I-avareji yefayibha idayamitha ye-polypropylene inyibilika ilaphu elivuthelweyo yi-2-5 μ m. Ubungakanani besuntswana elikhulu kune-5 emoyeni μ Amathontsi e-m anokuvalwa ngelaphu elinyibilikisiweyo; Xa ububanzi bothuli olucolekileyo lungaphantsi kwe-3 μ Kwi-m, ngenxa yokucwangciswa okungahleliwe kweentsinga kunye ne-interlayers kwilaphu elinyibilikayo elivuthelweyo, umaleko wokucoca ifayibha kunye neendlela ezininzi ezigobileyo zenziwe. Xa amasuntswana edlula kwiindidi ezahlukeneyo zemijelo egobileyo okanye iindlela, uthuli olucolekileyo lubhengezwa kumphezulu wemicu ngokucoca ngoomatshini amandla e-van der Waals; Xa ubungakanani be-particle kunye ne-airflow velocity zombini zikhulu, ukuhamba komoya kusondela kwi-filter material kwaye ijikeleze ngeenxa zonke ngenxa yokuphazamiseka, ngelixa iinqununu zikhupha kwi-streamline ngenxa ye-inertia kwaye zidibanise ngokuthe ngqo kunye neefayili eziza kubanjwa; Xa ubungakanani be-particle buncinci kwaye izinga lokuhamba liphantsi, iinqununu zisasazeka ngenxa yentshukumo ye-Brownian kwaye ingqubuzane neefayili eziza kubanjwa.

I-adsorption ye-electrostatic

I-adsorption ye-Electrostatic ibhekisela ekubanjweni kweengqungquthela ngumbutho we-Coulomb we-fiber ehlawulisiweyo (i-electret) xa iifayili zezinto zokucoca zihlawuliswa. Xa uthuli, iibhaktheriya, iintsholongwane, kunye namanye amasuntswana edlula kwizinto zokucoca, amandla e-electrostatic akatsali ngokufanelekileyo kuphela amasuntswana ahlawuliweyo, kodwa aphinde abambe amasuntswana angathathi hlangothi adityanisiweyo ngesiphumo sokungeniswa kwe-electrostatic. Njengoko amandla e-electrostatic enyuka, isiphumo se-electrostatic adsorption siba namandla.
