Muyezo woyesera nsalu zosalukidwa zopindika | JINHAOCHENG

Kodi muyezo wodziwira ndi chiyani? Nsalu Yopanda Ulusi ya SpunlaceLero ndifakitale yopanda nsalukuti ndikupatseni kufotokozera mwachidule.

Zopangidwa ndi nsalu zopanda nsalu ku China zimagwiritsidwa ntchito makamaka pazinthu zachipatala ndi zaukhondo, kupanga mafakitale opepuka, mafakitale amagetsi, kuteteza chilengedwe ndi madera ena, komanso ulusi wachikhalidwe waku China, chitukuko cha ulusi wosiyanasiyana chachita bwino pakulimbikitsa.

Nsalu yosalukidwa yokhala ndi zingwe ndi chinthu chofunikira kwambiri popanga chigoba chachipatala, zovala zodzitetezera kuchipatala, gauze yachipatala, zovala za opaleshoni ndi nsalu yoyambira yachikopa chochita kupanga. Makampani opanga zinthu ena akuda nkhawa ndi momwe angayang'anire mtundu wa nsalu yosalukidwa yokhala ndi zingwe pogwiritsa ntchito mayeso.

Njira zinayi zotsatirazi zopezera zinthu zosalukidwa ndi zingwe zozungulira kuti zigwiritsidwe ntchito

Nsalu zosalukidwa zolumikizidwa ndi zingwe zolumikizirana zimatha kuyang'aniridwa motsatira zomwe zili mu GB/T26379-2011 "Nsalu Zopanda Ulusi Zolumikizidwa ndi Nsalu Zopanda Ulusi Zolumikizidwa ndi Nsalu". Nsalu zosalukidwa ndi zingwe zolumikizirana za GB/T26379-2011 zimagawidwa m'magawo awiri: nsalu zolukidwa ndi zingwe zolumikizirana ndi nsalu zogwira ntchito zosalukidwa.

Pakati pawo, nsalu yopangidwa ndi zingwe zoluka ...

1. zinthu zodziwika bwino zamkati zopangidwa ndi spunthorn zomwe sizili zolukidwa:

kuchuluka kwa kupotoka kwa khalidwe pa dera la unit, kuchuluka kwa kusagwirizana kwa khalidwe pa dera la unit, mphamvu yothyoka yopingasa, kuyamwa, kufulumira kwa mtundu ku kukangana, kusiyana kwa m'lifupi;

2. Zinthu zoyeserera zamkati zogwiritsidwa ntchito popanga zinthu zosakanikirana zosakanikirana:

kuchuluka kwa kupotoka kwa khalidwe pa dera lililonse, kuchuluka kwa kusagwirizana kwa khalidwe pa dera lililonse, mphamvu yothyoka yopingasa, kufulumira kwa mtundu ku kukangana, kusiyana kwa m'lifupi, kugwira ntchito kosatuluka madzi, kugwira ntchito kogwirizana ndi madzi, kukana mowa, kugwira ntchito koletsa moto;

3. Zinthu zowunikira zakunja zakunja zopangidwa ndi nsalu yopanda ulusi:

zolakwika zolunjika, kudula ndi kuchotsa m'mphepete molakwika, kupukuta m'mphepete molakwika, zolakwika zosindikizira ndi utoto, nthawi yosokera, madontho, madontho amitundu, zodetsa, zolakwika zowonongeka, kuyika, madontho a tizilombo, ndi zina zotero.

Zovala zosakhala zoluka zopangidwa ndi ulusi wa Chitosan zitha kuyesedwa motsatira zomwe zalembedwa mu "Zovala Zosakhala Zoluka za Chitosan - Gawo 2: Zovala Zosakhala Zoluka" FZ/T 640772-2019. Zinthu zoyesera zopangidwa ndi ulusi wa Chitosan zopangidwa ndi ulusi wa Chitosan ndi thanzi lokhala ndi ulusi woluka zopangidwa ndi ulusi woluka zofanana, zomwe zimagawidwanso mu khalidwe lamkati, khalidwe lakunja, zinthu zitatu zazing'ono. Zofunikira zenizeni ndi izi:

1. Zinthu zoyesera khalidwe la mkati:

kuchuluka kwa kupotoka kwa misa pa dera lililonse, kusiyana kwa m'lifupi, mphamvu ya kusweka kwa longitudinal ndi transverse, kuchuluka kwa kupotoka kwa chitosan fiber, pH, kuchuluka kwa formaldehyde, kuwala kokhala ndi magwiridwe antchito osamutsidwa, kuyamwa kwamadzimadzi, kuchuluka kwa bacteriostatic, kuchuluka kwa zitsulo zolemera (lead, mercury, arsenic);

2. Zinthu zowunikira khalidwe lakunja:

pamwamba pa nsalu, cholumikizira, nkhope yodulira kumapeto;

3. Zinthu zodziwira zizindikiro za tizilombo toyambitsa matenda:

chiwerengero chonse cha mabakiteriya, ma coliform, ma fungal colonies, mabakiteriya a pathogenic pyogenic, ndi zina zotero.

Zovala zosaluka zoyera zoluka zitha kuyesedwa motsatira zomwe zili mu SANITARY Spunlaced Nonwovens FZ/T 64012-2013. FZ/T 64012-2013 imagawa zinthu zowunikira nsalu zosaluka zoyera m'magulu atatu: kuyang'anira khalidwe la mkati, kuyang'anira khalidwe lakunja ndi kuyang'anira microbial index. Zinthu zowunikira zenizeni ndi izi:

1. Zinthu zoyesera khalidwe la mkati:

kuchuluka kwa kupotoka kwa misa pa dera la unit, kusiyana kwa misa koyezera pa dera la unit, kusiyana kwa makulidwe, mphamvu yosweka, kupotoka kwa m'lifupi, kuyamwa kwa madzi, pH;

2. Zinthu zoyesera khalidwe lakunja:

zofooka za mtundu wa nsalu, kusiyana kwa mitundu, zofooka, ndi zina zotero;

3. Zinthu zodziwira ma microbial index:

chiwerengero chonse cha mabakiteriya, ma coliforms, Staphylococcus aureus, mabakiteriya a pathogenic pyogenic, ndi zina zotero.

Nsalu zoteteza ku kutchinjiriza zomwe zili ndi zingwe zopanda ulusi zitha kuyesedwa motsatira zomwe zili mu FZ/T 64065-2017 "Aron Spunlaced Nonwovens for Insulation". Zoteteza kutchinjiriza zomwe zili ndi zingwe zopanda ulusi ziyenera kuyesedwa kuti zizindikire mtundu wamkati ndi mtundu wakunja wa zinthu ziwirizi. Zofunikira zenizeni ndi izi:

1. Zinthu zoyesera khalidwe la mkati:

kuchuluka kwa kupotoka kwa misa pa gawo lililonse, kupotoka kwa makulidwe, kupotoka kwa m'lifupi, kuchepetsa kuchuluka kwa okosijeni, nthawi yoyaka yopitilira, nthawi yofuka, kutalika kwa kuwonongeka, mphamvu yamagetsi, mphamvu yosweka, kutalika kwa kusweka, mphamvu yong'ambika, nthawi yokhazikika ya dielectric, chinthu chotayika cha dielectric, kuchuluka kwa kufupika kwa kutentha;

2. Zinthu zoyesera khalidwe lakunja:

yunifolomu, nsalu yathyathyathya, yopanda mikwingwirima yoonekera, yopanda m'mbali zosweka, mabowo, mafuta, madontho ndi zina, pindani kuti mukonze bwino

Zomwe zili pamwambapa ndi mawu oyamba okhudzana ndi nsalu yosaluka, ngati mukufuna kudziwa zambiri zokhudza nsalu yosaluka, takulandirani kuti tilumikizane nafe.fakitale ya nsalu yopanda nsalu.
