Fiber isina kurukwa yakanyunguduka
Nzira yekunyunguduka inonyunguduka zvakare ndeimwe yepolymer zvakananga munet method, ndiyo screw extruder extrusion yepolymer inonyunguduka kuburikidza nemhepo inoputika nekupisa kwakanyanya kana imwe nzira yekunyungudutsa trickle extreme tension uye kuumbwa kwefiber yakanaka kwazvo, yozounganidzwa munet roller kana net curtain yakagadzirwa pafiber network, pakupedzisira inoita kuti adhesion iwedzere sezvo fiber inonyunguduka isina kubhururuka.
Nheyo yekuumbwa kwe fusion-jet fiber
1. Kufanana uye kusiyana nenzira ye spunbonded
Nzira yakasungirirwa
Inozivikanwawo senzira yekumonera zvakananga mujira, ikushandisa nzira dzekumonera dzakaita sechikamu chepolymer nekumonera kumonera uye kugadzirwa kwetambo inoenderera mberi, uyezve nekusunga, kupedzisa nezvimwe zvigadzirwa zvinogadzirwa.
Chinhu chakajairika
Iyo polymer inofanira kuburitswa neburi respinneret kana yakanyungudutswa.
(2) network yefiber inogona kuva yekubatana kwekupisa (kubatana kwepamusoro kana kubatana kwenzvimbo) kana kubatana kwayo pachayo mukusimbisa jira risina kurukwa
Musiyano weB
Munzira ye spunbond: mhepo inotonhora inotonhorera kamwe kamwe, panguva imwe chete, ichitambanudzwa, ichiumba shinda inoenderera mberi, ichipararira muketeni remambure.
Nzira yekupfapfaidza yakanyunguduka: kupfapfaidza mhepo inopisa nekukurumidza, nekutambanudza zvakanyanya, kuumbwa kwefiber pfupi yakapfava, nekumhanya kwakanyanya kuti ibhururuke ichipinda muchidzitiro cheneti kana kutenderedza net roller kuti igadzire network yefiber.
(2) nzira ye spunbond: nzira dzekusimbisa fiber network, kuwedzera kune hot bonding, asiwo kutora acupuncture, mvura, chemical bonding nedzimwe nzira
Nzira yekupfapfaidza yakanyunguduka: inonyanya kuvimba nekubatana kwekupisa kana kuzvibatanidza
2. Maitiro echinyakare etekinoroji
Kudyisa nePolymer → kunyungudutsa kwemafuta → kugadzirwa kwefiber → kutonhora kwefiber → kuumbwa kwemesh → kubatana (mesh yakagadziriswa) → kutenderedza mucheto wekucheka → kupedzisa mushure mekupedza kana kupedzisa kwakakosha
Kudya kwepolymer - polymer inowanzogadzirwa kuita zvidimbu zvidiki zvakatenderera, zvakatetepa, zvinodururwa mubhaketi kana hopper, uye zvinoiswa mu screw extruder
Kunyunguduka kwemvura -- pakupera kwekudyisa kwescrew extruder, polymer slice inofanira kusanganiswa ne stabilizer, whitening agent nezvimwe zvinowedzera, color masterbatch nezvimwe zvinhu zvakakosha, mushure mekusanganisa zvizere muscrew extruder, yodziiswa kuti inyunguduke, uye pakupedzisira melt ichaiswa mu spinneret nepombi yekuyera kuburikidza nefirita. Mukati mekunyunguduka nekupfapfaidza, general extruder inoderedzawo huremu hwemamorekuru epolymer nekushanda kwayo kwekuchekerera uye kuora kwekupisa.
Kuumbwa kwefiber - kunyunguduka kwakachena kwakaseferwa kunopfuura nemusystem yekugovera uye kunopihwa zvakaenzana mu seti yega yega ye spinnerets kuti kubudise huwandu hwakaenzana hwe extrusion pa spinneret. Spinneret ye fusion-sprayed fiber yakasiyana nedzimwe nzira dzekuspender, maburi e spinneret anofanira kurongwa mumutsara wakatwasuka, mativi ekumusoro neapasi ane maburi ejet.
Kutonhodza kwefiber - mhepo yakawanda inopinzwa mukamuri inosvetwa kumativi ese espinneret uye inosanganiswa nerukova rwemhepo inopisa ine microfiber kuti itonhodze. Microfiber yakanyungudutswa inotonhorera uye inooma.
Mambure - mukugadzirwa kwefiber nonwovens dzakarukwa ne fusion-blown, spinnerets dzinogona kuiswa dzakatwasuka kana dzakatwasuka. Kana dzikaiswa dzakatwasuka, microfiber inopfapfaidzwa padhiramu rinounganidza rakatenderera kuti igadzire mambure. Kana dzikaiswa dzakatwasuka, mambure anowira pachidzitiro chinofamba chakatwasuka kuti chigadzire mambure.
Namatira (network yakagadziriswa) - iyo self-namira reinforcement yataurwa pamusoro apa, kune zvimwe zvinangwa zve melting spray jira yakakwana, senge: zvinodiwa zve fiber network ine chimiro chakapfava, air retention yakanaka kana void ratio. Uye kune mamwe mashandisirwo akawanda, iwe pachako agglutinate aggrandizement chete haikwani, uchiri kuda hot rolling agglutination, ultrasonic agglutination kana dzimwe nzira dzekuwedzera. Hot glue
3. Hunhu hwemaitiro emhando yefiber isina kurukwa yakanyungudutswa
(1) maitiro mapfupi, kushanda zvakanaka kwekugadzira;
Faibha yacho yakanaka kwazvo, kufanana kwefiber mesh kwakanaka, kwakapfava, mukuchenesa, inorwisa mabhakitiriya, kunyungudutsa kune zvakanakira zvikuru;
Kutarisa kwefiber hakuna kunaka, simba re network yefiber rakaderera;
Izvi zvichatora simba rakawanda.
Maitiro makuru ekugadzira nzira yekupfapfaidza yakanyunguduka
1. Nhamba yekunyunguduka (MFI)
Simba nekureba kwejira rakapfapfaidzwa nekubatana kwakadzikira nekuwedzera kweMFI. Saka, MFI yezvinhu zvakagadziriswa inofanirwa kunge yakakwira zvakanyanya kuitira kuti kuyerera kwemvura kutetepa kuwedzere kuyerera zvakanaka mukupisa kwegasi.
2. Kumhanya kwemhepo inopisa
Pasi petembiricha yakafanana, kumhanya kwescrew, daro rekugamuchira uye mamwe mamiriro:
Mhepo inopisa kumhanya ↑ → dhayamita yefaibha ↓ → isina kurukwa inonzwa kubva pakaoma kusvika pakupfava, fiber tangles inowedzera, fiber network yakakora, yakatsetseka, simba rawedzera
Asi kumhanya kwemhepo kwakakura zvakanyanya, maruva ari kubhururuka ari nyore kuoneka, zvinokanganisa zvakanyanya chitarisiko chejira
3. Angle yekuisa jekiseni remhepo inopisa
Zvinonyanya kukanganisa tensile effect uye fiber morphology
Mashandisirwo uye mashandisirwo e melt-jet fiber (jira risina kurukwa)
1. Zvinhu zvekusefa
Inonyanya kushandisa chimiro chayo chefiber chakasimba kwazvo, chinova ndicho chiri chikamu chayo chekutanga uye chikuru chekushandiswa. Kudiwa kwezvinhu zvitsva zvefirita ndiko zvakare kuri kukurudzira kugadzirwa kwefiber nonwovens dzakanyunguduka.
Hapana ganda pfupi rechinhu chinosefa rinowira mugasi rakacheneswa kana mumvura mushure mekusefa nejira rekupfapfaidza rakanyunguduka.
Parizvino, matani anopfuura 20,000 emidziyo yekusefa ye melt-jet anoshandiswa pasi rose gore rega rega, 65% ayo anoshandiswa kusefa mvura, zvakaita se: kusefa zvinwiwa nekuchenesa chikafu, kusefa mvura, kusefa simbi inokosha, pendi nependi nezvimwe zvigadzirwa zvemakemikari; 35% inoshandiswa kusefa gasi, zvakaita se: kusefa mhepo inotonhodza mumba, kusefa mhepo nemvura, kusefa mukamuri rekuchenesa.
2. Zvinhu zvekurapa
Parizvino, ndiyo nzvimbo yechipiri pakukura inoshandiswa pakushandisa jira rinopfapfaidza.
Munzvimbo iyi, chiyero chikuru chinoshandiswa pakuvhiya, maketeni emukamuri rekuvhiyira uye jira rekuvhiya rekuuraya utachiona, uye bhandiji shoma, tepi, firimu rekudzivirira marwadzo rinorwisa kuzvimba.
3. Zvinhu zvehutsanana
(1) mumachira ekuchenesa
★ jira rinopfapfaidza rakanyungudika rakaiswa mukati mekunyudzwa kwenapukeni rekuchenesa, jira rekufambisa capillary
★ kushandiswa kwejira rekupfapfaidza rinonyungudutsa sechidziviriro kune chidziviriro chemvura chinopinda, nejira rekupfapfaidza rinonyungudutsa rakaita zvidimbu zviviri panzvimbo pefirimu risingapindi polyethylene
(2) kana tichitarisa manapukeni evakuru
Mukugadzirwa kwayo, shinda pfupi dzehuni dzinosanganiswa mukufamba kwemashinda efusiform kuti dzigadzire jira refusiform rakasiyana rinonyunguduka zvakanaka.
4. Zvinhu zvinotora mafuta
Sechinhu chinokweva mafuta, kugona kukweva mafuta kunogona kusvika ka17 kupfuura huremu hwacho.
Kazhinji, jira rinopfapfaidza rinoiswa muchubhu refu remambure rakarukwa kubva kuPET filament segridi yemvura inoyangarara kuti irambe mafuta uye inwe mafuta mugungwa. Rinogona zvakare kuiswa mumusoro wegungwa rinodhonza rakagadzirwa nePP melting spray cloth, richichenesa mafuta nguva dzose pamusoro.
5. Zvipfeko
(1) zvinhu zvinodziya
Chinonyanya kushandiswa ijira rakapfapfaidzwa rakagadziriswa nekambani ye3M muUnited States: mukugadzirwa kwefiber yakapfapfaidzwa, fiber yePET inosanganiswa kuti igadzire chimiro chekudzivirira mweya chakagadzirwa nefiber yePET ine elasticity yakanaka uye fiber yePP ultrafine.
(2) mbatya dzebasa dzinoraswa
Kushandiswa kukuru kwejira reSMS composite, pamusoro pejasi rekushanda, kwave kuchishandiswa zvinobudirira mukushandiswa kwezvipfeko zvekudzivirira mumaindasitiri.
6, jira rakachena
Kunyanya kushandiswa kwePP natural oil absorption, kushandiswa kwakasiyana-siyana kwekusvibisa mafuta munzvimbo yekushanda.
Nekufambira mberi kwetekinoroji yekugadzirisa kunyungudutsa nekupfapfaidza, jira rekunyungudutsa nekupfapfaidza rePP rine hunhu hwemvura rinogona kugadzirwa nechinowedzera hunyoro, chinogona kushandiswa muzvipatara, mumakamuri ekuchenesa zvakanyanya, muzvikamu zvemazvo, mumakamuri emakombiyuta.
