Kusiyana nsalu PET nonwoven ndi PP nonwoven nsalu

Polyester (PET) yopanda nsalu ndi chiyani? Nsalu za polyester (PET) zopanda nsalu ndi kusiyana kwa PP kosaluka;
Nsalu za polyester (PET) zopanda spunbond zosalukidwa ndi mtundu wosalukidwa, zopangira zake ndi tchipisi 100% za poliyesitala. Amakhala ndi ulusi wambiri wopanda malire kudzera pa spunbond yotentha yozungulira. Zomwe zimadziwikanso kuti PET spunbond non-woven fabric kapena PES spunbond non-woven, yomwe imadziwikanso kuti single-component spunbond non-woluka nsalu.

Zinthu za PET zopanda nsalu
choyamba, Nsalu ya polyester (PET) ya spunbond yosalukidwa ndi nsalu yopanda madzi yopanda nsalu, kutengera kulemera kwa mitundu yosiyanasiyana yothamangitsa madzi yomwe sinalukidwe ndiyosiyananso. Kulemera, kulemera, ndi bwino kuthamangitsa madzi. Ngati pali madontho amadzi pamwamba pa nsalu yopanda nsalu, madontho amadzi amachoka pamwamba pake.
Chachiwiri, kutentha kwakukulu. Chifukwa cha kusungunuka kwa poliyesitala pafupifupi 260 ° C, kutentha bata m'chilengedwe, mukhoza kukhala bata miyeso sanali nsalu nsalu. Zakhala zikugwiritsidwa ntchito kwambiri pakusindikiza kutentha, kusefera kwamafuta, ndipo zina zimafunikira zida zophatikizira kutentha kwambiri.
Chachitatu, polyester (PET) spunbond yopanda nsalu ndi yachiwiri kwa nayiloni spunbond yopanda nsalu ya ulusi wosalukidwa. Mphamvu zake zabwino kwambiri, kutha kwa mpweya wabwino, kukana kugwetsa misozi komanso zoletsa kukalamba zagwiritsidwa ntchito ndi anthu ochulukirapo m'magawo osiyanasiyana.
Chachinayi, ma polyester (PET) spunbond nonwovens alinso ndi mawonekedwe apadera kwambiri: anti-gamma ray. Izi zikutanthauza kuti, ngati zikugwiritsidwa ntchito kuzinthu zamankhwala, kuwala kwa gamma kumatha kutsekedwa mwachindunji popanda kusokoneza kukhazikika kwa thupi lawo ndi kukula kwake, zomwe sizipezeka muzinthu zakuthupi za nsalu za PP spunbond.

PP sanali nsalu ndi PET sanali nsalu kusiyana nsalu
PP ndi polypropylene yaiwisi, ndiko kuti, polypropylene CHIKWANGWANI, ndi woonda sanali nsalu; PET ndi zida zatsopano za poliyesitala, ndiye kuti, ulusi wa poliyesitala, njira yonse yopangira popanda zowonjezera, ndi zinthu zabwino kwambiri zoteteza chilengedwe, ndi nsalu zokhuthala zosalukidwa.
(PP) polypropylene yosawomba ndi (PET) polyester yopanda nsalu kuyerekezera:
1, PP zotsika mtengo zopangira, PET zopangira zokwera mtengo. Zinyalala za PP zitha kubwezeretsedwanso, PET sizingasinthidwenso, chifukwa chake mtengo wa PP ndiwotsika pang'ono.
2, PP kutentha kwambiri pafupifupi madigiri 200, pamene PET pafupifupi madigiri 290, PET ndi kuposa PP kutentha kwambiri.
3.non wolukidwa kusindikiza, kutentha kutengerapo kanthu, m'lifupi chomwecho PP contraction, PET shrinkage, zotsatira zake ndi bwino, PET ndi ndalama zambiri ndi zochepa zinyalala.
4, Rally, kukangana, katundu wonyamula mphamvu, kulemera komweko, PET kumakoka kuposa PP, mavuto, kubereka mphamvu. 65 magalamu a PET ndi ofanana ndi 80 magalamu a PP kupsinjika, kupsinjika, kunyamula katundu.
5, malo owonera zachilengedwe, PP chifukwa cha kukana kwa PP, PET tchipisi tatsopano ta polyester, PET yokonda zachilengedwe kuposa PP yaukhondo.

PET nonwovens osiyanasiyana ntchito
① Zovala Zanyumba: zotchingira zotsutsana ndi velvet, kusindikiza kwamafuta, makalendala osalukidwa, zikalata zamaofesi zopachikidwa, makatani, matumba otsukira, matumba otaya zinyalala.
② kuyika: nsalu za chingwe, zikwama zam'manja, matumba a chidebe, zida za paketi, desiccant, adsorbent ma CD.
③ kukongoletsa: nsalu yokongoletsera khoma, nsalu yachikopa, nsalu zoyandama.
④ ulimi: nsalu zokolola zaulimi, chitetezo cha mbewu ndi mbewu, tepi yoteteza udzu, matumba a zipatso ndi zina zotero.
⑤ zinthu zopanda madzi: nsalu yapamwamba yopuma (yonyowa) yopanda madzi.
⑥ ntchito zamakampani: zosefera, zida zotchingira, zida zamagetsi, zida zolimbikitsira, zida zothandizira.
⑦ zina: zida zodzitetezera, zinthu zokopa alendo.
⑧ fyuluta: kufalitsa mafuta fyuluta.
