Nsalu Zopanda Ulusi za Aramid

I. Makhalidwe Abwino a Aramid Spunlace Nonwoven Fabrics: Kuyerekeza Magwiridwe Abwino M'malo Ovuta Kwambiri

Nsalu zopanda ulusi za Aramid spunlace zimagwiritsa ntchito ubwino wa ulusi wa aramid ndi kapangidwe ka ukadaulo wa spunlace kuti zipange zinthu zitatu zazikulu, zomwe zimadutsa bwino zovuta za nsalu zachikhalidwe zopanda ulusi pazochitika zotentha kwambiri komanso zoopsa kwambiri:

1. Kukana Kutentha Kwambiri + Kubwerera kwa Moto: "Chotchinga Chotetezera" mu Zochitika Zotentha Kwambiri

Kukhazikika kwa kutentha kwa nthawi yayitali: Mosiyana ndi ulusi wamba monga polypropylene (kukana kutentha ≤ 120°C) ndi polyester (kukana kutentha ≤ 150°C), ulusi wa aramid ukhoza kugwira ntchito mokhazikika pa 200°C kwa nthawi yayitali, ndi kukana kutentha kwa nthawi yochepa mpaka 250°C. Pambuyo polimbitsa spunlace, kukana kutentha koyambirira kwa ulusi kumakhalabe, ndipo kumatha kugwiritsidwa ntchito mosalekeza kwa miyezi yoposa 6 m'malo otentha kwambiri monga kusungunula chitsulo ndi kusakaniza phula, popanda kukalamba kapena kuwonongeka, komwe kuli kuwirikiza katatu mpaka kasanu kuposa zipangizo zachikhalidwe zokana kutentha kwambiri.

Kuletsa Moto Kofunika Kwambiri Popanda Zoopsa: Palibe zinthu zina zoletsa moto zomwe zimafunika. Chizindikiro cha mpweya ndi ≥ 28% (choposa muyezo wa 28% wa polypropylene yosinthidwa yoletsa moto), ndipo sichimayaka kapena kusungunuka chikayaka moto, chimangopangidwa ndi carbonization yokhala ndi kapangidwe kokhazikika ka carbon layer, zomwe zimathandiza kupewa kufalikira kwa moto ndikuthetsa ululu wa nsalu zachikhalidwe zosaluka moto "kusungunuka kwa moto ndi kugwa" m'malo otentha kwambiri.

2. Mphamvu Yapamwamba + Modulus Yapamwamba: "Maziko Omanga" mu Zochitika Zolemera

Kugwira ntchito kwa makina kuposa zipangizo wamba: Kuchuluka kwa ulusi wa aramid ndi 1.416g/cm³, kokwera pang'ono kuposa polypropylene, koma mphamvu yosweka ya longitudinal ndi transverse imatha kufika 1000N/5×20cm, yomwe ndi nthawi 50 kuposa polypropylene; ndipo modulus ndi yayikulu kwambiri, yokhala ndi kuchuluka kwa kusintha kwa ≤ 2% pambuyo pa kugwiritsa ntchito mphamvu. Pambuyo polimbitsa njira ya spunlace yodutsana, ulusiwo umakokedwa kwambiri, ndi magwiridwe antchito abwino kwambiri oletsa kung'ambika, okhoza kupirira kugundana kwa zinthu zolemera kapena kukangana kwapamwamba popanda kuwonongeka.

Palibe kutayika kwa mphamvu mukakhala wonyowa: Mosiyana ndi ulusi wa thonje womwe mphamvu yake imachepa ndi 40% mutatenga chinyezi ndi ulusi wa viscose womwe umatupa mosavuta ukakumana ndi madzi, nsalu zopanda nsalu za aramid spunlace zimasunga mphamvu 100% m'malo ozizira, ndipo zimakhala ndi kukana kwabwino kwa asidi ndi alkali, kuposa nsalu wamba zopanda nsalu zoluka munthawi yolimba munyengo yozizira komanso yowononga.

3. Kukonza Kosinthasintha + Kugwirizana ndi Ntchito: "Maziko Osinthira" a Kusintha Kwapamwamba

Njira ya spunlace imasunga ubwino wa ulusi: Pogwiritsa ntchito mphamvu ya spunlace yosinthasintha yolimbitsa, palibe kuwonongeka kwa kapangidwe ka ulusi ndi singano, mawonekedwe a chinthucho ali pafupi ndi nsalu zachikhalidwe, zokhala ndi kapangidwe kofewa komanso zopindika bwino, ndipo zimatha kudulidwa ndikusokedwa mu mawonekedwe aliwonse, kuthetsa vuto la "kulimba komanso kusweka, kukonza kosayenera" kwa ma felt a aramid needle-punch.

Kuthekera kwakukulu kogwirizana ndi ntchito: Kudzera mu njira zochizira pambuyo pa chithandizo monga fluorine coating ndi anti-static functions, imatha kuphatikizidwa ndi fluorine treatment kuti pamwamba pake pasamamatire ku madontho a mafuta, oyenera kusefa kutentha kwambiri; ndipo ikaphatikizidwa ndi maukonde a nsalu ya spunlace, imakhala ndi mphamvu zambiri komanso mphamvu yothira madzi, ikukwaniritsa zofunikira zapamwamba kwambiri.

II. Kugwiritsa Ntchito Kwambiri Magawo a Aramid spunlace Nonwoven Fabrics: Mayankho Ofunikira pa Zochitika Zapamwamba

Kutengera ndi zinthu zapakati zomwe zili pamwambapa, nsalu zopanda nsalu za aramid spunlace zakhala chinthu chofunikira kwambiri m'mafakitale omwe amatentha kwambiri, chitetezo, komanso kusefa kwapamwamba, kuyang'ana kwambiri maulalo apakati omwe ali ndi zofunikira zambiri, zoopsa zambiri, komanso mtengo wake wapamwamba:

1. Malo Opangira Mafakitale: "Woyang'anira Kupanga" M'malo Ovuta Kwambiri Malo Osefera Kutentha Kwambiri: Matumba osefera fumbi a ma boiler a magetsi, nsalu zosefera utsi m'malo osakanizira a phula - Kusefera fumbi mosalekeza pa 200°C pamalo otentha kwambiri, ndi kulondola kwa kusefera kwa 1-5 μm. Imatha kugwira tinthu tating'onoting'ono ta fumbi ndipo imalimbana ndi dzimbiri la asidi ndi alkali, yokhala ndi moyo woposa chaka chimodzi, womwe ndi wautali kawiri kuposa nsalu zosefera zagalasi zachikhalidwe, zomwe zimachepetsa kwambiri kuchuluka kwa kukonza zida ndi ndalama.

Chitetezo cha makina: Zophimba kutentha kwa zipangizo zachitsulo, ma pad otentha kwambiri a makina osungira mabuleki a magalimoto - Palibe kusintha ngakhale pansi pa 250°C kutentha kwa nthawi yochepa, kuletsa kutentha kwakukulu komwe kumachitika chifukwa cha ntchito ya zida, kuteteza zigawo zozungulira ku kuwonongeka kwa kutentha; ndipo ndi mphamvu yayikulu, imatha kupirira kukangana kwapamwamba kwa makina osungira mabuleki, koyenera makina olemera monga magalimoto ndi zitsulo.

Chitetezo chosatha: Nsalu yosatha yogwiritsira ntchito zida zoyendera migodi, nsalu yophimba yoteteza ku kukwawa kwa makina omangira - Yolimba kwambiri, yokhoza kupirira kukhudzidwa ndi kukangana kwa mchere ndi miyala yamchenga, yokhala ndi kuchuluka kwa kutayika kwa makulidwe a ≤ 5% pambuyo pa kukangana kobwerezabwereza 100,000, komwe ndi kuwirikiza ka 10 kuposa nsalu wamba yosatha yogwiritsa ntchito polyester, kuchepetsa ndalama zogwirira ntchito.

2. Chitetezo cha chitetezo: "Life Line" pazochitika zoopsa kwambiri

Zipangizo zodzitetezera: Mbali yakunja ya zovala zozimitsa moto za ozimitsa moto, ma apuloni oteteza a wowotcherera - Osatentha komanso osatentha kwambiri mwachibadwa, amatha kuletsa malawi ndi kutentha kwambiri, kuteteza ogwira ntchito ku kutentha; ndipo ndi kapangidwe kofewa, sizimakhudza kuyenda kwa miyendo, kuthetsa vuto la zida zodzitetezera zachikhalidwe "zolemera komanso zoletsa".

Zipangizo zopulumutsira anthu mwadzidzidzi: Mabulangeti othawira moto a nyumba zazitali, nsalu zotetezera anthu mwadzidzidzi m'malo osungira mafuta - Zikayaka moto, zimapanga mpweya wokhazikika wa kaboni, womwe ungakulungitse thupi la munthu kapena kuphimba zinthu zomwe zikutuluka, kuletsa malawi ndi mpweya woipa. Kulemera kwake ndi 60% yokha ya nsalu yachikhalidwe yosapsa moto, kuphatikiza kunyamulika ndi chitetezo, choyenera kuyankha mwachangu populumutsa anthu mwadzidzidzi.

3. Kusefa kwapamwamba kwambiri ndi minda yapadera: "Performance Core" m'zochitika zenizeni

Kusefa kwa mankhwala kwapamwamba: Nsalu zosefera zamadzimadzi zowononga kwambiri, zipangizo zosefera zoyeretsera kutentha kwambiri - Zosagwira asidi ndi alkali komanso zotetezeka kutentha kwambiri, zimatha kusefa zipangizo zopangira mankhwala pamalo a asidi amphamvu a 180°C, popanda kusakaniza zigawo zamadzimadzi a fyuluta, kuonetsetsa kuti chinthucho chili choyera; komanso popanda kutaya ulusi, kukwaniritsa miyezo yoyera ya makampani opanga mankhwala, zomwe zimapangitsa kuti ikhale chisankho chapamwamba kwambiri chomwe sichingasinthidwe ndi zipangizo zachikhalidwe zosefera.

Zipangizo zapadera zamagetsi: Ma pad oteteza zinthu zamagetsi otentha kwambiri, zolekanitsa moto za batire ya lithiamu - Zimasunga kukhazikika kwa magwiridwe antchito a insulation pa 200°C kutentha kwakukulu ndipo zimaletsa moto, zimateteza bwino ma short circuits ndi moto wamagetsi; mu ntchito za batire ya lithiamu, zimatha kuletsa dzimbiri la electrolyte komanso zimathandizanso pakuletsa moto ndi kuphulika, zoyenera kupanga mphamvu zatsopano.

Zokhudza Yongdeli: Katswiri wopanga nsalu zopanda nsalu za aramid spunlace

Changshu Yongdeli Spunlaced Non-woven Fabric Co., Ltd., yodalira ukadaulo wopanga spunlace wokhwima, imatha kupereka nsalu zopangidwa mwapadera za aramid spunlace zopanda ulusi zokhala ndi kulemera kwa 50-500 g/㎡ ndi m'lifupi mwa 0.2-3.2 m, zothandizira njira zokonzera pambuyo monga kutsuka, kupukuta, ndi kupaka utoto.

Ngati mukufuna kudziwa za zitsanzo za malonda kapena mapulani osinthira, chonde musazengereze kulankhulana nafe.
