Biodegradable polypropylene composite spunbond nonwoven jira

Nekuda kweiyo saturated kabhoni kabhoni imwe bond molecular chimiro chepolypropylene, hukama hwayo hwemamorekuru hwakadzikama uye hwakaoma kudzikisira nekukurumidza. Nepo iri rakapfava polypropylene spunbond nonwoven jira richiunza kurerukira mukugadzirwa kwevanhu nehupenyu, rinokonzerawo kumwe kusvibiswa kwezvakatipoteredza. Naizvozvo, kugadzirira uye tsvakiridzo yezvakatipoteredza uye biodegradable polypropylene composite spunbond nonwoven jira inonyanya kukosha. Polylactic asidhi ndeye biodegradable polymer ine yakanakisa biocompatibility uye michina zvivakwa. Inogona kusanganiswa ne polypropylene raw materials kugadzira biodegradable polypropylene composite spunbond nonwoven machira, nokudaro kuderedza kusvibiswa kwezvakatipoteredza kunokonzerwa ne polypropylene spunbond nonwoven machira.

Kuita kwe biodegradable polypropylene composite spunbond nonwoven jira

Mukugadzira biodegradable polypropylene composite spunbond nonwoven jira, zvinhu zvakaita sekumhanya kwepombi yemetering, tembiricha inopisa yekukunguruka, uye tembiricha yekutenderera zvinogona kuve nemhedzisiro yakakosha pahunhu hwemucheka we spunbond nonwoven. Rongedza zvinoenderana nezvinodiwa nemutengi sehuremu, ukobvu, kusimba kwesimba, nezvimwe.

Kufurira kwe metering pombi kumhanya

Nekumisa akasiyana metering pombi kumhanya, iyo fiber zvimiro zveyakagadzirirwa composite faibha filaments, senge linear density, faibha dhayamita, uye fiber fracture simba, inoongororwa kuti ione iyo yakakwana metering pombi kumhanya kwekuita kweakagadzirirwa akaumbwa fiber filaments. Panguva imwecheteyo, nekuisa akasiyana metering pombi kumhanya kuongorora maitiro ekuita senge huremu, ukobvu, uye kusimba kwesimba rakagadzirwa rakagadzirwa spunbond nonwoven jira, iyo yakakwana metering pombi yekumhanya inogona kuwanikwa nekubatanidza iyo fiber zvimiro uye isina kurukwa zvimiro zvemusanganiswa spunbond nonwoven jira.

The pesvedzero inopisa rolling tembiricha

Nekugadzirisa mamwe maparamendi ekugadzirira uye kuseta magiyo akasiyana-siyana uye tembiricha yekutenderedza inopisa, pesvedzero yekupisa inoputika tembiricha pazvinhu zveyakagadzirirwa composite fiber filaments inodzidzwa nekuongororwa. Kana kupisa kunopisa kwekusimbisa tembiricha yeguyo inoputika yakadzikira zvakanyanya, mafibhi anopisa-akatenderedzwa haagone kunyungudika zvizere, zvichikonzera maitiro asina kujeka uye kutadza kunzwa kwemaoko. Tichitora gadziriro yebiodegradable polylactic acid/additive/polypropylene composite spunbond isiri-yakarukwa jira semuenzaniso, kana kupisa kunopisa kwekusimbisa tembiricha kunosvika 70 ℃, iyo composite faibha mitsetse yakajeka uye pane kushoma kunamatira kumupumburu, saka 70 ℃ yekumisikidza yasvika pakusimba kwepamusoro tembiricha.

Kufurira kwekutenderera tembiricha

Kurudziro yetembiricha yekutenderera kwakasiyana pane zvimiro zvecomposite fiber tambo density, faibha dhayamita, uye faibha kutsemuka simba, pamwe nehunhu hwebiodegradable polypropylene composite spunbond nonwoven jira, uku uchigadzirisa mamwe maitiro ekugadzirira maparamita.

Process tekinoroji kuyerera kweiyo biodegradable polypropylene composite spunbond nonwoven jira

(1) Cheka polylactic acid, polypropylene, uye maleic anhydride graft copolymer uye uzvisanganise muzvikamu zvakakodzera;

(2) Shandisa extruder yegranulation uye muchina wekuruka wekuruka;

(3) Sefa kuburikidza nesefa yakanyunguduka uye gadzira mesh pasi pechiito chepombi yekumisikidza, yekuomesa inovhuvhuta, uye yekumhanya-mhanya kuyerera kwemhepo kuyerera;

(4) Gadzira machira ane spunbond asina kurukwa kuburikidza neanopisa anotenderedza bonding inosimbisa, inomonereka, uye reverse kucheka.
