Iyini indwangu encibilikisiwe engalukiwe

Iyini indwangu engalukiwe ephephethwa yi-Melt

Indwangu engalukiwe ephephethwa yi-Melt iwuhlobo olusha lwempahla yendwangu eyenziwe ngezinto ezisezingeni eliphezulu ze-polymer ngokusebenzisa izinqubo ezifana nokulungiswa kwempahla eluhlaza, ukuncibilika kwezinga lokushisa eliphezulu, ukubumba kwesifutho, ukupholisa nokuqiniswa. Uma kuqhathaniswa nenaliti yendabuko ephonswe izindwangu ezingezona ezilukiweyo, izindwangu ezincibilikisiwe ezicibilikile zinesakhiwo se-fiber esicolekile nesifana kakhulu, kanye nokuphefumula okuthile nokumelana namanzi, okubenza babe isiqondiso esibalulekile sokuthuthukiswa emkhakheni wezinto zendwangu.

Izici zendwangu engalukiwe ephephethwa yincibilika

1. Ukusebenza kahle kokuhlunga, okungavimba ngempumelelo ukusabalala kwezinto eziyingozi njengezinhlayiya, amagciwane, amagciwane, njll;

2. Ithambile futhi inethezekile, ikwazi ukuphefumula kahle, ukugqoka kahle, futhi akukho ukungezwani komzimba;

3. Ukungagqoki, ukumelana namanzi kanye nowoyela, impilo ende yesevisi nokuqina okuhle kakhulu;

4. Kulula ukucubungula, okukwazi ukusika, ukuthunga, ukucindezela okushisayo, i-laminating nokunye ukwelashwa ngokwezidingo ezahlukene.

Ukusetshenziswa kwendwangu engalukiwe ephephethwa yincibilika

Indwangu engalukiwe encibilikisiwe inohlu olubanzi lwamathemba okusebenza, futhi iye yahlolwa emikhakheni efana nokunakekelwa kwezempilo, inhlanzeko, nempahla yasendlini. Izindawo eziyinhloko zesicelo yilezi:

1. Ezokwelapha Nezempilo: Indwangu engalukiwe ephephethwa yi-Melt isetshenziswa kakhulu ekukhiqizeni izinto zokuvikela ezifana namamaski, izingubo zokuhlinza, nezingubo zokuzihlukanisa, ezingahlukanisa ngempumelelo amagciwane namagciwane, kuqinisekiswe ukuphepha kwabasebenzi bezokwelapha neziguli.

2. Impahla Yasekhaya: Indwangu engalukiwe ephephethwayo encibilikayo isetshenziselwa ukwenza izidingo zansuku zonke ezifana nezinto zokusula ezimanzi, izinto zokuhlanza ubuso, nezingubo zokugeza ezimunca kahle amanzi, ukumelana namanzi, futhi akulula ukuchithwa izinwele, ukuthuthukisa ulwazi lomsebenzisi.

3. Izinto zokuhlunga: Indwangu engalukiwe ephephethwa ngokuncibilika ingenziwa ibe izinto zokuhlunga umoya, amanzi, namafutha, ezingasusa ngokuphumelelayo izinhlayiya ezisemoyeni futhi zinciphise ukungcola. Ingasetshenziswa futhi emikhakheni efana nokuhlunga ngomshini kanye nokuhlunga kwamanzi okuphuza.

Indwangu engalukiwe ephephethwa yi-Melt iyinto enhle yokwahlukanisa

Indwangu engalukiwe encibilikisiwe inendawo enkulu ethize kanye ne-voids encane (usayizi we-pore ≤ 20) μ m) I-porosity ephezulu (≥ 75%) nezinye izici. Uma ububanzi obumaphakathi bungu-3 μ Indawo ethile yendawo ethile yemicu yendwangu encibilikisiwe engalukiwe, elingana nesilinganiso se-fiber density engu-0.0638 dtex (nosayizi wefayibha ongu-0.058 denier), ifinyelela ku-14617 cm2/g, kuyilapho ububanzi obuyisilinganiso bungu-15.3 μ Indawo ethize eyi-fiber eyisilinganiso eyi-nonwoven eyi-fiber emaphakathi ukuminyana kwe-1.65 dtex (nosayizi wefayibha engu-1.5), kungu-2883 cm2/g kuphela.

Ngenxa yokuhanjiswa komoya okushisayo okuncane kakhulu uma kuqhathaniswa nemicu evamile, umoya osezimbotsheni zendwangu engalukiwe encibilikayo unciphisa ukuguquguquka kwawo okushisayo. Ukulahlekelwa ukushisa okudluliselwa nge-fiber material yendwangu engalukiwe ephephethwayo encibilikayo kuncane, futhi ungqimba lomoya omile ongaphezulu kwenqwaba yemicu ye-ultrafine ivimbela ukushintshaniswa kokushisa okubangelwa ukugeleza komoya, kuyenze ibe nemiphumela emihle yokwaleka neyokufudumala.

I-Polypropylene (PP) i-fiber iwuhlobo lwe-fiber material ekhona ene-conductivity ephansi kakhulu ye-thermal. I-thermal insulation floc eyenziwe ngefayibha ye-PP ngemva kokwelashwa okukhethekile ine-insulation eshisayo ephindwe izikhathi ezingu-1.5 kuneyaphansi kanye nephindwe izikhathi ezingu-15 kunokotini oshisayo ovamile. Ikakhulukazi ifaneleka ukwenza izingubo zokushushuluza, izingubo zokuqwala izintaba, okokulala, izikhwama zokulala, izingubo zangaphansi ezishisayo, amagilavu, izicathulo, njll. Imikhiqizo enobubanzi obungu-65-200g/m2 isetshenziselwe ukwenza izingubo ezifudumele zamasosha ezindaweni ezibandayo.

Indlela yokuthuthukisa ukusebenza kahle kokuhlunga kwendwangu encibilikisiwe engalukiwe

Ncibilikisa indwangu engalukiwe, njengezinto eziwumgogodla zamamaski ezokwelapha, ukusebenza kahle kwayo kokuhlunga kuthinta ngqo umphumela wokuvikela wemaski. Kunezici eziningi ezithinta ukusebenza kokuhlunga kwezindwangu ezingalukiwe ezincibilikisiwe, njenge-fiber linear density, ukwakheka kwe-fiber mesh, ukujiya, kanye nokuminyana. Njengento yokuhlunga umoya kumaski, uma impahla iqine kakhulu, izimbotshana zincane kakhulu, futhi ukumelana nokuphefumula kuphezulu kakhulu, umsebenzisi akakwazi ukuhogela umoya ngokushelela, futhi imaski ilahlekelwa inani layo lokusetshenziswa. Lokhu kudinga ukuthi izinto zokuhlunga zingathuthukisi kuphela ukusebenza kahle kwazo kokuhlunga, kodwa futhi zinciphise ukumelana kwazo nokuphefumula, okuwukuphikisana phakathi kokumelana nokuphefumula nokusebenza kahle kokuhlunga. Inqubo yokwelashwa kwe-electret ye-electret iyindlela enhle yokuxazulula ukungqubuzana phakathi kokumelana nokuphefumula nokusebenza kahle kokuhlunga.

Isithiyo semishini

Isilinganiso se-fiber diameter ye-polypropylene ephephethwa yindwangu encibilikayo ingu-2-5 μ m. Usayizi wezinhlayiyana ezinkulu kuno-5 emoyeni μ Amaconsi ka-m angavinjwa ngendwangu encibilikisiwe; Lapho ububanzi bothuli olucolile bungaphansi kuka-3 μ At m, ngenxa yokuhlelwa okungahleliwe kwemicu kanye nama-interlayers endwangu encibilikayo encibilikayo, ungqimba lwesihlungi se-fiber esineziteshi eziningi ezigobile siyakhiwa. Lapho izinhlayiya zidlula ezinhlotsheni ezihlukahlukene zamashaneli noma ezindleleni ezigobile, uthuli olucolekileyo lukhangiswa ebusweni bemicu ngokusefa ngomshini amandla e-van der Waals; Lapho usayizi wezinhlayiya kanye nesivinini sokugeleza komoya kokubili kukhulu, ukugeleza komoya kusondela ezintweni zokuhlunga futhi kugeleze nxazonke ngenxa yokuvinjelwa, kuyilapho izinhlayiya zihlehla emgudwini ngenxa ye-inertia futhi zishayisane ngokuqondile nemicu ezobanjwa; Uma usayizi wezinhlayiyana mncane futhi izinga lokugeleza liphansi, izinhlayiya ziyasakazeka ngenxa yokunyakaza kwe-Brownian bese zishayisana nemicu ezobanjwa.

I-adsorption ye-electrostatic

I-electrostatic adsorption ibhekisela ekuthathweni kwezinhlayiya ngamandla e-Coulomb efayibha eshajiwe (i-electret) lapho imicu yezinto zokuhlunga ishajwa. Lapho uthuli, amagciwane, amagciwane, nezinye izinhlayiya zidlula ezintweni zokuhlunga, amandla e-electrostatic awadonseli kuphela izinhlayiya ezikhokhisiwe, kodwa futhi athwebula izinhlayiya ezingathathi hlangothi ezenziwe nge-polarized ngokusebenzisa umphumela wokungeniswa kwe-electrostatic. Njengoba amandla e-electrostatic enyuka, umphumela we-electrostatic adsorption uba namandla.
