Ehe saizvozvo. Kuvandudza kuramba kubvarura kwemachira e spunbond nonwoven ipurojekiti yakarongeka inosanganisira optimization yezvinhu zvakawanda, kubva kune zvigadzirwa uye maitiro ekugadzira kusvika pakupedzisa. Kuramba kubvarura kwakakosha pakuchengetedza mashandisirwo akadai sembatya dzekudzivirira, sezvo zvine chekuita nekusimba kwechinhu uye kuchengetedzeka kana ichinge yabatwa netsaona nekudhonzwa.
Idzi dzinotevera ndidzo nzira huru dzekuvandudza kuramba kubvarura kwespunbond nonwoven machira:
Raw Material Optimization: Kuvaka Nheyo Yakasimba
Kusarudza High-Toughness Polymers:
Yakakwira Molecular Weight / Narrow Molecular Weight Distribution Polypropylene: Rebesa molecular cheni uye yakakura entanglement inokonzeresa kusimba kwepamusoro uye kuoma.
Copolymerization kana Blending Modification: Kuwedzera hushoma hwe polyethylene kana mamwe elastomers kune polypropylene. Kuunzwa kwePE kunogona kushandura maitiro ekristallisation yezvinhu, kuvandudza kuchinjika uye kukanganisa kuramba, nekudaro zvinobudirira kuvandudza kuramba kubvarura.
Kuwedzera Impact Modifiers: Kuunza akasarudzika elastomers kana nhanho dzerabha sezvo kushushikana kwenzvimbo kunogona kutora uye kuparadzira simba rekubvarura, kudzivirira kupararira kwekuputika.
Kushandisa High-Performance Fibers:
PET uyePP Composites: Kuunza polyester fiber panguva ye spunbonding process. PET, ine yakakwira modulus uye simba, inozadzisa PP fibers, inosimudzira zvakanyanya kusimba kwese kwefiber network.
Kushandisa bicomponent fibers, se "island-type" kana "core-sheath" zvimiro. Semuenzaniso, kushandisa PET se "core" yesimba uye PP se "sheath" yekunamatira kupisa, kubatanidza zvakanakira zvese zviri zviviri.
Kugadzira Maitiro Kudzora: Kugadzirisa Fiber Network Structure
Iri ndiro danho rakakosha pakuvandudza kusada kubvarura.
Spinning uye Kudhirowa Matanho:
Kuvandudza Fiber Strength: Kunatsiridza kukurumidza kudhirowa uye tembiricha inobvumira kutarisisa kwakazara uye crystallization yepolymer macromolecules, zvichikonzera yakakwirira-simba, yakakwirira-modulus monofilament fibers. Monofilaments yakasimba ndiyo nheyo dzemicheka yakasimba.
Kudzora Fiber Fineness: Paunenge uchivimbisa kugadzikana kwekugadzirwa, zvakakodzera kuderedza fiber dhayamita kunowedzera huwandu hwefiber pane imwe unit nzvimbo, zvichiita kuti fiber network iwedzere uye ichibvumira zviri nani kugovera mutoro pasi pekunetseka.
Webhu Kugadzira uye Kusimbisa Matanho:
Kuvandudza Fiber Oriental Randomness: Kudzivirira yakawandisa unidirectional fiber alignment. Kugadzirisa kuyerera kwemhepo webhu kugadzira tekinoroji inogadzira isotropic fiber network. Nenzira iyi, zvisinei negwara resimba rinobvarura, nhamba huru yemafibhi anochinjika anoipikisa, zvichiita kuti pave nekuenzanisa kwepamusoro kurira kwemisodzi.
Optimized Hot Rolling Process:
Bond Point Dhizaini: Kushandisa "diki-doti rakazara" roll-up pateni. Diki, dense bond point inovimbisa kukwana kwechisungo kusimba pasina zvakanyanya kukanganisa kuenderera kwefiber, zvinobudirira kuparadzira kushushikana mukati meiyo yakakura fiber network uye kudzivirira kushushikana kusungirirwa.
Tembiricha uye Kudzvanya: Kunyatso kudzora tembiricha inopisa yekutenderedza uye kudzvanywa kunovimbisa kusanganiswa kwakazara kwemafiber panzvimbo dzebhondi pasina kudzvanyirira kwakanyanya kunogona kukuvadza kana kumisa fiber pachayo.
Hydroentangling Reinforcement: Kune zvimwe zvinhu, hydroentangling inoshandiswa seimwe nzira kana kuwedzera kune inopisa kukungurutswa. Kuyerera kwemvura yakakwira-kudzvanya kunoita kuti mafiibhi apinze, achigadzira chimiro chetatu-dimensional chakavharika. Ichi chimiro chinowanzoita zvakanakisa mukuramba kubvarura uye zvinoguma nechigadzirwa chakapfava.
Kupedzisa uye Kubatanidza Tekinoroji: Kuunza Kunze Kusimbisa
Lamination/Composite Technology:
Iyi ndiyo imwe yenzira dzakananga uye dzinoshanda. Spunbond nonwoven jira rinosanganiswa neshinda, jira rakarukwa, kana imwe layer yejira re spunbond rine mativi akasiyana.
Nheyo: Mafilamende ane simba repamusoro mumambure kana machira akarukwa anoumba macroscopic reinforcing skeleton ayo anokanganisa zvakanyanya kupararira kwemisodzi. Ichi ndicho chaicho chimiro chinowanzo shandiswa mune yakakwirira-chivharo zvipfeko zvekudzivirira, uko kushorwa kwemisodzi kunonyanya kubva kune yekunze reinforcing layer.
Impregnation Kupedzisa:
Iro jira re spunbond rinopinzwa neakakodzera emulsion yepolymer uye robva raporeswa pamharadzano dzefiber. Izvi zvakanyanya kuwedzera kusimba kwekubatana pakati pemafayibha, nekudaro zvichivandudza simba rekubvarura, asi zvinogona kupa kumwe kupfava uye kufema.
Pfupiso uye Pfungwa Huru
Kuti uvandudze kuramba kubvarura kwemachira e-spunbond asina kuruka, nzira ine-multi-pronged inowanzodiwa:
Level | Nzira | Basa Rinokosha
Raw Materials | Shandisa yakakwirira-kusimba mapolymer, musanganiswa gadziriso, wedzera elastomers | Wedzera simba uye kuwedzera kwefiber imwe neimwe
Production Process | Optimize kunyora, gadzira isotropic fiber webs, optimize inopisa rolling / hydroenangling process | Gadzira yakasimba, yunifomu faibha network dhizaini ine yakanaka kusagadzikana kupararira
Kupedza | Laminate neshinda, impregnate | Isai ekunze ekusimbisa masisitimu kuti adzivise kubvarura
Pfungwa yepakati haisi kungoita kuti fiber yega yega ive yakasimba, asi zvakare kuve nechokwadi chekuti iyo yose fiber network dhizaini inogona kunyatso kupararira uye kutora simba kana yakatarisana nekubvarura masimba, pane kubvumira kushushikana kuisa pfungwa uye kupararira nekukurumidza pane imwe pfungwa.
Mukugadzirwa chaiko, musanganiswa wakakodzera unofanirwa kusarudzwa zvichienderana nekupera kwechigadzirwa kushandiswa, mutengo webhajeti, uye chiyero chekuita (sekupenya kwemhepo uye kupfava). Semuenzaniso, kune yakakwirira-inoshanda ine ngozi yemakemikari inodzivirira zvipfeko, iyo sandwich inoumbwa chimiro che "high-simba spunbond jira + yakakwirira-barrier firimu + mesh reinforcement layer" ndiyo chiyero chegoridhe panguva imwe chete kuwana yakakwirira kubvarura kuramba, puncture kuramba uye kuchengetedzwa kwemakemikari.
Dongguan Liansheng Non woven Technology Co., Ltd.yakavambwa muna Chivabvu 2020. Ibhizimusi rekugadzira jira rakakura risingarukwe rinobatanidza tsvakiridzo nekusimudzira, kugadzira, uye kutengesa. Inogona kuburitsa mavara akasiyana-siyana ePP spunbond machira asiri akarukwa ane hupamhi husingasviki 3.2 metres kubva pa9 gramu kusvika 300 magiramu.
