Core performance: misiyano yakakosha muhunhu hwekuzvarwa
1. Mechanical properties uye kugadzikana
Polyester spunbond: Yakagadzirwa kubva kupolyester (PET) seyakagadzirwa, simba rekusimba rinogona kusvika 1.5-2 nguva yepolypropylene, ine reberi uye inochinjika simba musiyano weisingasviki 5%, uye chiyero chekuchengetedza simba chinodarika makumi mapfumbamwe muzana mumamiriro ekunyorova, akakodzera kwenguva refu yekushushikana mamiriro. Kuramba kwayo kwechiedza ndeyechipiri kune acrylic fiber, uye mushure memaawa 1000 ekuratidzwa kwezuva, simba rayo rinogona kuchengetwa ne60-70%. Hupenyu hwayo hwebasa rekunze hunogona kusvika kupfuura makore mashanu. .
Polypropylene spunbond: Kuwanda kwepolypropylene (PP) zvinhuinongova 0.91g/cm ³, zvichiita kuti ive chikamu chakareruka pakati pezvakajairwa kemikari fiber. Ukobvu hwezvigadzirwa zvine huremu hwakafanana 30% yakakwirira kupfuura polyester, uye fluffiness iri nani. Asi ine kugadzikana kwakashata kwemafuta, kupfava pa70-80 ℃ uye kunyunguduka kwepamusoro pe150 ℃. Iyo zvakare ine isina kusimba kuchembera uye inogara kune brittleness kana ichishandiswa kunze pasina UV kurapwa. .
2. Kushivirira Kwemakemikari uye Kwezvakatipoteredza
Polyester spunbond ine tembiricha yenguva refu yekudzivirira ye260 ℃ uye tembiricha yenguva pfupi ye300 ℃. Iyo inodzivirira kemikari, inoshingirira asidhi, uye isiri alkali inoshingirira, ine mwero wekutorwa kwemwando isingasviki 0.5%. Iantibacterial, moth proof, uye mold proof.
Polypropylene spunbond ine tembiricha yenguva refu yekudzivirira ye120 ℃ uye tembiricha yenguva pfupi ye150 ℃. Inoshingirira kumakemikari, acids, alkalis, uye yakawanda organic zvinonyungudutsa, ine mwero wekutorwa kwemwando we ≈ 0%. Iyo ine yakanakisa kunyura kwepakati uye antibacterial properties, inoparadzanisa kukukurwa kwebhakitiriya uye kuwana zvirinani antibacterial properties.
3. Kushanda kuchinjika
Polyester spunbond: High density inogona kuwanikwa kuburikidza nekupisa kutenderera kusimbiswa, uye mhepo inopenya inogona kudzorwa pakati pe50-500L/m² · s, yakakodzera kusefa zvinhu; Polypropylene spunbond: Yechisikigo inodzinga mvura (contact angle> 130°), inogona kushandiswa pamusoro pezvigadzirwa zvehutsanana mushure mekugadzirisa hydrophilic, ine core suction speed ye0.3cm/s. .
Maitiro maitiro: kusiyanisa tekinoroji pakupera kwekugadzira
1. Kuenzanisa kwepakati kutenderera parameters
Polyester spunbond spinning tembiricha i285-290 ℃, yekudhirowa kumhanya i4000-6000m/min, screw aspect ratio inofanira kunge ≥ 27, raw material pretreatment inofanira kunge yakaoma (hunyoro hwemukati <0.05%);Polypropylene spunbond20 tembiricha irikutenderera 20 20, kudhirowa kuri kuita 272 ℃ 27. 2000m/min, screw urefu dhayamita reshiyo i25-27 zvichienzaniswa neyakajairika, uye mbishi pretreatment haidi kuomeswa.
.
2. Zvishandiso uye Kudzora Mutengo
Polyester spunbond: inoda hunyanzvi hwekuomesa michina, ine simba rekushandisa 15-20% yakakwira kupfuura polypropylene, asi chigadzirwa chakapedzwa chine huremu hwepamusoro (± 2g/m²); Polypropylene spunbond: inoenderana ne30% yakadzokororwa yekuwedzera zvinhu, kudyara kwemidziyo kuri 10-15% kuderera, uye yakakwirira-frequency inopisa kunyunguduka kugadzirisa kushanda i30% yakakwirira kupfuura polyester. .
Mamiriro ekushandisa: kudiwa-yakatarisana nesarudzo pfungwa
1. Kupatsanurwa kwenzvimbo dzinonyanya kushandiswa
Sarudzo yakasarudzika yekudzivirirwa kwekurapa ndeyepolypropylene spunbond(SMS chimiro), iyo ine yakasimba antibacterial uye isina-chepfu zvivakwa, uye kusefa inoshanda inopfuura 95%.
Polyester spunbond inofarirwa kusefa kwemaindasitiri nekuda kwekukwira kwayo tembiricha kuramba, saizi yakagadzikana, uye kugona kucheneswa kakawanda.
Sarudzo inosarudzika yekuvhara yekurima ndeye polypropylene spunbond (UV inodzivirira), nechikonzero chikuru chiri chekuti polypropylene kuruka ine light viscosity, yakaderera mutengo, uye inogona kuderera mukati memakore 1-5.
Sarudzo inosarudzika yemukati memotokari ndeye polyester spunbond, nechikonzero chikuru chiri kuramba kwayo kuchembera, kuvharisa ruzha kwakanaka, uye kuramba kwenguva refu kune tembiricha yepamusoro inosvika 120 ℃.
Sarudzo yakasarudzika yezvigadzirwa zvehutsanana ndeye polypropylene spunbond, nechikonzero chikuru chiri chekuti iyo polypropylene spunbond musimboti inokurumidza kunyura, inodzinga mvura zvivakwa, uye kubata kwakapfava.
2. Muenzaniso wekuongorora nyaya
Gown rekuvhiya rekurapa: rakagadzirwa ne30g/m² polypropylene SMS composite jira, rakagadzirwa neanti doro uye anti plasma zvivakwa, nekunyorova kwemhepo> 2000g/m² · 24h; Yepamusoro tembiricha yekusefa bhegi: Yakagadzirwa 200g/m² polyester spunbond jira uye rakaputirwa ne PT8 mwedzi inoenderera ℃; Jira rinoratidza huswa: 60g/m² jira reUV rinopesana nepolypropylene spunbond, rine simba rinobvarura rinopfuura 80N, uye hupenyu hwesevhisi hunosvika makore matatu. .
Economy uye Musika Patani
1. Mutengo wekuumbwa kuenzanisa (kutora 80g/m² chigadzirwa semuenzaniso)
Raw material cost: Polyester chips (8500 yuan/ton) vs polypropylene chips (7200 yuan/ton), ane polypropylene chips ari 15.3% pasi; Mutengo wekugadzira: Polyester (1.2 yuan/m²) vs Polypropylene (0.9 yuan/m²), Polypropylene yakaderera ne25%; Comprehensive cost: Polypropylene spunbond iri 18-22% yakaderera pane polyester. .
2. Musika wemusika uye maitiro
Mumucheka wepasi rose we spunbond nonwoven, polypropylene accounts inosvika 70% uye polyester account ye18%; Mundima yezvokurapa, chikamu chepolypropylene SMS chimiro chekugadzira simba chakawedzera kubva pa12% muna 2020 kusvika 37.6% muna 2024, uye inotarisirwa kudarika 48% ne2025; Mundima yeindasitiri,polyester spunbondyakawana kukura kwepagore kwe8.2% mumusika wepamusoro-tembiricha yekusefa nekuda kwekusimudzira kwekuita. .
Kuchengetedzwa Kwezvakatipoteredza uye Kubudirira Kwakasimba
Kudzokorodza: Zvese zviri thermoplastic zvinhu. Polyester recycling inoda kupisa kwakanyanya kunyunguduka (yakanyanya kushandiswa kwesimba), nepo polypropylene recycling inoda tembiricha yakaderera (30% kuchengetedza simba). Zvakadaro, chiyero chekuchengetedza simba repolyester yakadzokororwa i85%, iri nani pane yepolypropylene yakadzokororwa (70%);
Degradation maitiro: Polypropylene inogona kuwana mutsauko wechisikigo kwemakore 1-5 nekuwedzera degradation masterbatch, nepo polyester inoda chaiyo enzymatic hydrolysis mamiriro ane degradation kutenderera kweanopfuura makore makumi maviri; .
Carbon tsoka: Kugadzirwa kwepolypropylene kunoburitsa anenge 3.2 matani eCO ₂ patani, iyo yakaderera pane polyester (5.1 matani eCO ₂). .
Ultimate Choice Guide
Kunyanya kunofanira kupiwa kune polypropylene spunbond: kana kudiwa kuri kwemutengo wakaderera, wakareruka, unodzinga mvura, unoraswa (zvakadai semasikisi, zvigadzirwa zvehutsanana, kuchengetedzwa kwenguva pfupi); .
Kunyanya kunofanirwa kupihwa polyester spunbond: kana kudiwa kuri kwesimba rakanyanya, kupisa kwekushisa kwepamusoro, kuramba kuchembera, uye kushandiswa kwenguva refu (senge maindasitiri sefa zvinhu, zvekunze zvekuvakisa, uye zvemukati zvemotokari); .
Mamiriro akakosha: Sarudza polypropylene SMS inosanganiswa yekudzivirira kwekurapa kwepamusoro, firimu repolyester rekusefa kwepamusoro-tembiricha, uye UV inodzivirira polypropylene yekuvhara kwenguva refu yekurima. .
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.
