Imikorere yibanze: itandukaniro ryingenzi mubiranga kavukire
1. Ibikoresho bya mashini no gutekana
Polyester spunbond: Yakozwe muri polyester (PET) nkibikoresho fatizo, imbaraga zingana zirashobora kugera ku nshuro 1.5-2 zingana na polypropilene, hamwe n’itandukaniro rirerire kandi rihinduranya imbaraga riri munsi ya 5%, kandi igipimo cyo kugumana imbaraga kiri hejuru ya 90% mubihe bitose, bikwiranye nigihe kirekire cyo guhangayika. Kurwanya urumuri rwa kabiri nyuma ya fibre acrylic, kandi nyuma yamasaha 1000 yo kubona urumuri rwizuba, imbaraga zayo zirashobora kugumana 60-70%. Ubuzima bwa serivisi yo hanze bushobora kugera kumyaka irenga 5. ?
Polypropilene spunbond: Ubucucike bwaibikoresho bya polypropilene (PP)ni 0,91g / cm gusa ³, ikaba icyiciro cyoroheje muri fibre isanzwe. Ubunini bwibicuruzwa bifite uburemere bumwe burenze 30% kurenza polyester, kandi fluffness nibyiza. Ariko ifite ubushyuhe buke bwumuriro, koroshya 70-80 ℃ no gushonga hejuru ya 150 ℃. Ifite kandi intege nke zo kurwanya gusaza kandi ikunda guhindagurika iyo ikoreshejwe hanze itavuwe na UV. ?
2. Kwihanganira imiti n’ibidukikije
Polyester spunbond ifite uburebure bwigihe kirekire cyo kurwanya ubushyuhe bwa 260 ℃ nubushyuhe bwigihe gito bwa 300 ℃. Irwanya imiti, irwanya aside, kandi irwanya alkali, hamwe n’igipimo cyo kwinjiza amazi kiri munsi ya 0.5%. Ni antibacterial, inyenzi, hamwe nibimenyetso.
Polypropilene spunbond ifite uburebure bwigihe kirekire bwo kurwanya ubushyuhe bwa 120 ℃ nubushyuhe bwigihe gito bwa 150 ℃. Irwanya imiti, acide, alkalis, hamwe nudukoko twinshi twinshi, hamwe nubushyuhe bwa ≈ 0%. Ifite intangarugero nziza yo kwinjiza no kurwanya antibacterial, gutandukanya isuri ya bagiteri no kugera kuri antibacterial nziza.
3. Guhuza n'imikorere
Polyester spunbond: Ubucucike bwinshi burashobora kugerwaho hifashishijwe imbaraga zishyushye, kandi ikirere gishobora kugenzurwa hagati ya 50-500L / m ² · s, kibereye gushungura ibikoresho; Polypropilene spunbond: Irwanya amazi karemano (impande zombi) ?
Ibiranga inzira: gutandukanya tekinoloji kurangiza umusaruro
1. Kugereranya ibice byingenzi bizunguruka
Ubushyuhe bwa polyester spunbond ni 285-290 ℃, umuvuduko wo gushushanya ni 4000-6000m / min, igipimo cya screw kigomba kuba ≥ 27, kwitegura ibikoresho fatizo bigomba kuba byumye (ibirimo ubushuhe <0.05%); Polypropilene spunbond izunguruka ni 220-295 ℃, umuvuduko wo gushushanya ni 2000m / min, kugereranya ibipimo bya diameter ni 25-27 ugereranije nibisanzwe
?
2. Ibikoresho no kugenzura ibiciro
Polyester spunbond: isaba ibikoresho byumye byumye, hamwe nogukoresha ingufu hejuru ya 15-20% kurenza polypropilene, ariko ibicuruzwa byarangiye bifite uburemere buke (± 2g / m ²); Polypropilene spunbond: ihujwe na 30% byongeweho ibikoresho byongeye gukoreshwa, ishoramari ryibikoresho riri munsi ya 10-15%, kandi uburyo bwo gutunganya amashanyarazi ashyushye buri hejuru ya 30% kuruta polyester. ?
Icyerekezo cyo gusaba: icyifuzo-cyo guhitamo ibitekerezo
1. Kugabana ibice byiganjemo gusaba
Guhitamo guhitamo kurinda ubuvuzi nipolypropilene spunbond(Imiterere ya SMS), ifite antibacterial ikomeye kandi idafite uburozi, hamwe no kuyungurura hejuru ya 95%.
Polyester spunbond ikundwa kuyungurura inganda bitewe nubushyuhe bwayo bwinshi, ingano ihamye, hamwe nubushobozi bwo kozwa inshuro nyinshi.
Guhitamo guhitamo gukwirakwiza ubuhinzi ni polypropilene spunbond (UV irwanya UV), hamwe nimpamvu nyamukuru nuko kuzunguruka polypropilene bifite ubukonje bworoheje, bidahenze, kandi birashobora kwangirika mumyaka 1-5.
Guhitamo kwimodoka imbere ni polyester spunbond, hamwe nimpamvu nyamukuru ni ukurwanya gusaza, kwifata neza kwijwi, hamwe no kurwanya igihe kirekire ubushyuhe bwo hejuru bugera kuri 120 ℃.
Guhitamo guhitamo ibicuruzwa by isuku ni polypropilene spunbond, hamwe nimpamvu nyamukuru nuko polypropilene spunbond yibintu byinjira vuba, ibintu byangiza amazi, hamwe no gukorakora byoroshye.
2. Isesengura risanzwe
Ikanzu yo kubaga ubuvuzi: ikozwe muri 30g / m ² polypropilene SMS igizwe, ikavurwa hamwe na anti-alcool hamwe na anti-plasma, hamwe n’ubushuhe bwa> 2000g / m ² · 24h; umufuka w’ubushyuhe bwo hejuru: Wakozwe mu mwenda wa 200g / m ² polyester spunbond kandi ushyizwemo na firime ya PTFE, urashobora gukoreshwa ubudahwema amezi 18 kuri 200 ℃; Imyenda yerekana ibyatsi: 60g / m ² UV irwanya polypropilene spunbond, ifite imbaraga zo kurira zirenze 80N, hamwe nubuzima bwa serivisi kugeza kumyaka 3. ?
Ubukungu nicyitegererezo cyisoko
1. Kugereranya ibiciro byo kugereranya (gufata 80g / m ² ibicuruzwa nkurugero)
Igiciro cyibikoresho bito: Chipi ya polyester (8500 yuan / toni) vs polypropilene chip (7200 yuan / toni), hamwe na chipi ya polypropilene iri munsi ya 15.3%; Igiciro cyo gutunganya: Polyester (1,2 yuan / m ²) vs Polypropilene (0,9 yuan / m ²), Polypropilene iri munsi ya 25%; Igiciro cyuzuye: Polypropilene spunbond iri munsi ya 18-22% ugereranije na polyester. ?
2. Umugabane wamasoko nibigenda
Mu mwenda wa spunbond ku isi yose, polipropilene igera kuri 70% naho polyester igera kuri 18%; Mu rwego rw'ubuvuzi, igipimo cy'ubushobozi bwa SMS ya polypropilene cyiyongereye kiva kuri 12% muri 2020 kigera kuri 37,6% muri 2024, bikaba biteganijwe ko kizarenga 48% muri 2025; Mu nganda,polyester spunbondyageze ku iterambere ryumwaka wa 8.2% mumasoko yo hejuru yubushyuhe bwo hejuru kubera kuzamura imikorere. ?
Kurengera ibidukikije n'iterambere rirambye
Gusubiramo: Byombi nibikoresho bya termoplastique. Gusubiramo polyester bisaba ubushyuhe bwo hejuru gushonga (gukoresha ingufu nyinshi), mugihe gutunganya polipropilene bisaba ubushyuhe buke (kuzigama ingufu 30%). Nyamara, igipimo cyo kugumana imbaraga za polyester yongeye gukoreshwa ni 85%, bikaba byiza kuruta ibya polipropilene ikoreshwa neza (70%);
Ibiranga gutesha agaciro: Polypropilene irashobora kugera kubitandukanya karemano kumyaka 1-5 hiyongereyeho igishushanyo mbonera, mugihe polyester isaba imiterere ya hydrolysis ya enzymatique idasanzwe hamwe nizunguruka ryimyaka 20; ?
Ikirenge cya Carbone: Umusaruro wa polipropilene usohora toni 3.2 za CO ₂ kuri toni, ukaba uri munsi ya polyester (toni 5.1 za CO ₂). ?
Igitabo Cyiza cyo Guhitamo
Ibyingenzi bigomba guhabwa polipropilene spunbond: mugihe ibisabwa ari kubiciro bidahenze, biremereye, byangiza amazi, bikoreshwa (nka masike, ibicuruzwa by isuku, kurinda by'agateganyo); ?
Ibyingenzi bigomba guhabwa polyester spunbond: mugihe ibisabwa ari imbaraga nyinshi, kurwanya ubushyuhe bwinshi, kurwanya gusaza, no gukoresha igihe kirekire (nkibikoresho byo kuyungurura inganda, ibikoresho byo kubaka hanze, hamwe n’imodoka imbere); ?
Ibihe bidasanzwe: Hitamo SMS igizwe na polypropilene SMS ikingira ubuvuzi bwo mu rwego rwo hejuru, firime ya polyester yo kuyungurura ubushyuhe bwo hejuru, hamwe na UV irwanya polypropilene kugirango ikore ubuhinzi igihe kirekire. ?
Dongguan Liansheng Ntabwo Yubatswe Ikoranabuhanga Co, Ltd.yashinzwe muri Gicurasi 2020.Ni uruganda runini rutunganya imyenda rudahuza ubushakashatsi niterambere, umusaruro, no kugurisha. Irashobora gutanga amabara atandukanye ya PP spunbond idoda idoda hamwe n'ubugari bwa metero 3.2 kuva kuri garama 9 kugeza kuri garama 300.
