Kuonjezera Gulu Lachitetezo: Nsalu Yophatikizika Yapamwamba ya Spunbond Imakhala Chida Chachikulu Chazovala Zowopsa Zoteteza Chemical

M'ntchito zowopsa kwambiri monga kupanga mankhwala, kupulumutsa moto, ndi kutaya mankhwala owopsa, chitetezo cha ogwira ntchito kutsogolo ndi chofunika kwambiri. “Khungu lawo lachiŵiri”—zovala zotetezera—limagwirizana mwachindunji ndi kupulumuka kwawo. M'zaka zaposachedwa, chinthu chotchedwa "high-barrier composite spunbond nsalu" chakhala chikuwoneka ngati chinthu chotsogolera, ndipo ndi ntchito yake yapamwamba kwambiri, yakhala chinthu chofunika kwambiri cha zovala zotetezera mankhwala owopsa kwambiri, kumanga mzere wolimba wotetezera chitetezo cha ntchito.

Mabotolo a Zida Zachikhalidwe Zotetezera

Tisanamvetsetse nsalu za spunbond zotchinga kwambiri, tiyenera kuyang'ana zovuta zomwe zida zachikhalidwe zimakumana nazo:

1. Nsalu Zotchinga Mpira / Pulasitiki: Ngakhale kuti akupereka zinthu zabwino zotchinga, zimakhala zolemetsa, zosapumira, komanso zimakhala zovuta kuvala, zomwe zimapangitsa kuti kutentha kukhale kosavuta komanso kumakhudza kugwira ntchito komanso nthawi yayitali.

2. Nsalu Zosalukidwa Wamba: Zopepuka komanso zotsika mtengo, koma zopanda zotchinga zokwanira, zomwe zimapangitsa kuti asathe kukana kulowa kwa mankhwala amadzimadzi kapena agasi.

3. Nsalu Zophatikizika za Microporous Membrane: Ngakhale kuti akupereka mpweya wabwino, mphamvu zawo zotchinga zimakhalabe zochepa kwa mankhwala owopsa omwe ali ndi ma molekyulu ang'onoang'ono kwambiri kapena mankhwala enaake, ndipo kukhazikika kwake kungakhale kosakwanira.

Mabotolo awa alimbikitsa kufunikira kwa mtundu watsopano wazinthu zomwe zingapereke chitetezo cha "ironclad" komanso kuonetsetsa chitonthozo ndi kulimba.

Nsalu Yapamwamba Yotchinga ya Spunbond: Kusanthula kwaukadaulo

Nsalu ya spunbond yokhala ndi zotchinga zapamwamba si chinthu chimodzi, koma mawonekedwe a "sandwich" omwe amamangiriza mwamphamvu zigawo zosiyanasiyana zogwirira ntchito pogwiritsa ntchito njira zapamwamba. Ubwino wake waukulu umachokera ku izi:

1. Spunbond Nonwoven Base Layer: "Skeleton" Yamphamvu

Ntchito: Pogwiritsa ntchito zipangizo monga polypropylene (PP) kapena polyester (PET), wosanjikiza wamphamvu kwambiri, wosagwedera, komanso wosasunthika amapangidwa mwachindunji kupyolera mu spunbonding. Chosanjikiza ichi chimapereka mphamvu zamakina kwambiri komanso kukhazikika kwazinthu zonse, kuonetsetsa kuti zovala zoteteza siziwonongeka mosavuta panthawi yovuta.

2. High-Barrier Functional layer: "Chishango" chanzeru

Ichi ndicho maziko a teknoloji.Kawirikawiri, filimu yowombedwa ndi co-extrusion imagwiritsidwa ntchito popanga ma resin angapo apamwamba kwambiri (monga polyethylene, ethylene-vinyl alcohol copolymer EVOH, polyamide, etc.) kukhala filimu yowonda kwambiri koma yogwira ntchito kwambiri.

Katundu Wotchinga Kwambiri: Zida monga EVOH zimawonetsa zotchinga zapamwamba kwambiri polimbana ndi zosungunulira, mafuta, ndi mpweya wosiyanasiyana, zomwe zimalepheretsa kulowa kwa mankhwala owopsa amadzimadzi ndi mpweya.

Kulowetsa Kosankha: Kupyolera mu kupanga ma resins osiyanasiyana ndi mapangidwe a masanjidwe, chitetezo chokhazikika komanso chothandiza kwambiri ku mankhwala enaake (monga ma acid, alkalis, ndi zosungunulira zapoizoni) zitha kupezedwa.

3. Njira Yophatikizika: Chomangira Chosasweka

Kupyolera mu njira zapamwamba monga kutentha-press lamination ndi adhesive dot lamination, filimu yotchinga kwambiri imamangirizidwa mwamphamvu ndispunbond nsalu m'munsi wosanjikiza. Kapangidwe kaphatikizidwe kameneka kamapewa zovuta monga delamination ndi kubwebweta, kuwonetsetsa kukhulupirika ndi kudalirika kwa zinthuzo pamoyo wake wonse.

N'chifukwa Chiyani Yakhala Nkhani Yofunika Kwambiri?— Ubwino Zinayi

Nsalu ya spunbond yokhala ndi chotchinga chapamwamba kwambiri imadziwika chifukwa imayendetsa bwino mbali zingapo zofunika pakuvala zodzitetezera:

Ubwino 1: Chitetezo Chotsimikizika Kwambiri

Amatchinga bwino mankhwala owopsa osiyanasiyana, kuphatikiza ma hydrocarbon onunkhira, ma halogenated hydrocarbon, ma acid, ndi alkalis. Kusasunthika kwake kumaposa kwambiri miyezo ya dziko ndi miyezo yapadziko lonse lapansi monga European EN ndi American NFPA, kupatsa ogwiritsa ntchito "chitetezo chomaliza."

Ubwino 2: Kukhalitsa Kwambiri ndi Kudalirika

Nsalu ya spunbond yoyambira imapangitsa kuti ikhale yolimba kwambiri, kung'ambika, komanso kukhumudwa, zomwe zimapangitsa kuti zisawonongeke m'malo ovuta kugwira ntchito komanso kuchepetsa chiopsezo cholephera kuteteza chitetezo chifukwa cha mikwingwirima ndi kuvala.

Ubwino Wachitatu: Chitonthozo Chokwezeka Kwambiri

Poyerekeza ndi zovala zoteteza mphira zopanda mpweya, zotchinga kwambirinsalu yopangidwa ndi spunbondnthawi zambiri imakhala yabwino kwambiri **kupuma komanso kutulutsa chinyezi **. Amalola kuti thukuta lopangidwa ndi thupi litulutsidwe ngati nthunzi yamadzi, kuchepetsa kusungunuka kwamkati, kusunga wovala wowuma, kuchepetsa kwambiri kutentha kwa ogwira ntchito, ndikuwongolera bwino ntchito ndi chitetezo.

Ubwino Wachinayi: Wopepuka komanso Wosinthika

Zovala zodzitchinjiriza zopangidwa kuchokera ku zinthuzi ndi zopepuka komanso zofewa kuposa zovala zodzitchinjiriza zachikhalidwe za rabara/PVC pomwe zimatetezanso mulingo womwewo kapena wapamwamba kwambiri. Izi zimapatsa ovala ufulu woyenda, kuwongolera magwiridwe antchito mopepuka kapena mwamphamvu kwambiri.

Zochitika Zantchito ndi Zomwe Zamtsogolo

Pakali pano, nsalu zotchinga kwambiri za spunbond zimagwiritsidwa ntchito kwambiri mu:

Makampani a Chemical: Kuyang'ana pafupipafupi, kukonza zida, komanso kugwiritsa ntchito mankhwala owopsa.

Moto ndi Kupulumutsa: Kupulumutsa mwangozi ndi mankhwala owopsa komanso kuwononga zinthu zowopsa.

Emergency Management: Kuyankha kwadzidzidzi pamalopo ndi dipatimenti yachitetezo cha anthu ndi chitetezo cha chilengedwe.

Chitetezo cha Laboratory: Ntchito zokhala ndi mankhwala oopsa komanso owononga.

Tsogolo Lamtsogolo: M'tsogolomu, nkhaniyi ifika ku **zanzeru komanso ntchito zambiri **. Mwachitsanzo, kuphatikiza luso lozindikira kuti liwunikire kulowetsedwa kwa mankhwala pamalo opangira zovala komanso momwe thupi lake lilili munthawi yeniyeni; Kupanga zida zotchingira zachilengedwe komanso zoteteza zachilengedwe kuti zikwaniritse chitetezo chobiriwira m'moyo wonse.

Mapeto

Chitetezo ndichofunika kwambiri, ndipo zovala zotchinjiriza ndiye njira yomaliza yachitetezo cha moyo. Nsalu za spunbond zotchinga kwambiri zotchinga, kudzera pakuphatikizana kozama kwa sayansi ndiukadaulo wa nsalu, zimagwirizanitsa bwino zomwe zimawoneka ngati zotsutsana za "chitetezo chachikulu" ndi "chitonthozo chachikulu." Kugwiritsa ntchito kwake kofala mosakayikira kumapereka chilimbikitso chowonekera ku chitetezo cha ogwira ntchito m'mafakitale omwe ali pachiwopsezo chachikulu, kuwonetsa chiyambi cha nyengo yatsopano ya zida zodzitetezera zogwira ntchito kwambiri.

Dongguan Liansheng Non Woven Technology Co., Ltd.idakhazikitsidwa mu Meyi 2020. Ndi bizinesi yayikulu yopanda nsalu yopanga nsalu kuphatikiza kafukufuku ndi chitukuko, kupanga, ndi malonda. Itha kupanga mitundu yosiyanasiyana ya nsalu za PP spunbond zosalukidwa ndi m'lifupi mwake osakwana 3.2 metres kuchokera pa 9 magalamu mpaka 300 magalamu.
