Kodi Nsalu Yosungunuka Ndi Chiyani? | JINHAOCHENG

Kodi nsalu yosungunuka ndi chiyani?nsalu yosalukidwa yosungunukaWopanga Jin Haocheng kuti akudziwitseni, zomwe zili mkati mwake ndi izi:

Nsalu yopangidwa ndi polypropylene yosungunuka yokhala ndi ulusi wa maikuloni 1 mpaka 5. Ma voids ambiri, kapangidwe kofewa, kukana kupindika bwino. Kapangidwe kapadera ka microfiber kameneka kamapangitsa kuti chiwerengero cha ulusi pa dera lililonse ndi malo enaake a pamwamba chiwonjezeke.

Kuti nsalu yosungunuka ikhale ndi kusefa bwino, kuteteza, kutenthetsa komanso kuyamwa mafuta. Ndi yoyenera kusefa mpweya ndi madzi, zinthu zotenthetsera kutentha, zinthu zoyamwa, chigoba cha nkhope, zinthu zosungira kutentha, zoyamwa mafuta, zopukutira ndi zina.

Kugwiritsa ntchito nsalu yosungunuka

Nsalu zachipatala ndi zaumoyo: diresi yochitira opaleshoni, zovala zodzitetezera, nsalu yophimba ndi mankhwala ophera tizilombo toyambitsa matenda, masks, matewera, zopukutira zaukhondo za akazi, ndi zina zotero.

Nsalu yokongoletsera nyumba: nsalu ya pakhoma, nsalu ya patebulo, nsalu yogona, nsalu yophimba pabedi, ndi zina zotero;

Nsalu yopangira zovala: nsalu yophimba, nsalu yomatira, flocculant, thonje lopangira zinthu, mitundu yonse ya zikopa zopangidwa, ndi zina zotero.

Nsalu ya mafakitale: fyuluta, zinthu zotetezera kutentha, thumba lolongedza simenti, geotextile, nsalu yokutidwa, ndi zina zotero.

Nsalu yaulimi: nsalu yoteteza mbewu, nsalu ya mbande, nsalu yothirira, nsalu yotetezera kutentha, ndi zina zotero. 

Zina: thonje la m'mlengalenga, zinthu zotetezera kutentha, chofewetsera mafuta, fyuluta ya utsi, thumba la thumba la tiyi, ndi zina zotero.

Kodi kusiyana kwa nsalu yosungunuka ndi yosalukidwa ndi kotani?

Nsalu yosungunuka imapangidwa makamaka ndi polypropylene yokhala ndi ulusi wotalika mpaka ma microns 1-5. Makinawa ali ndi mitundu yosiyanasiyana ya kutseguka, kapangidwe kofewa, komanso magwiridwe antchito abwino oletsa kupindika. Microfiber ili ndi kapangidwe kapadera ka capillary, komwe kumawonjezera kuchuluka kwa ulusi pagawo lililonse komanso malo enaake.

Zipangizo zosefera ndi zofewa za polypropylene microfibers zomwe zimagawidwa mwachisawawa, mawonekedwe oyera, osalala, ulusi wofewa wa ulusi wa 0.5-1.0 digiri ya zinthuzo, kufalikira kosakhazikika kwa ulusi wa ulusi kumapereka mwayi wochulukirapo wogwirizanitsa kutentha.

Nsalu yosungunuka imakhala ndi ntchito yabwino yosefera, kuteteza, kutchinjiriza komanso kuyamwa mafuta. Ingagwiritsidwe ntchito ngati fyuluta ya mpweya ndi madzi, zinthu zolekanitsa, zinthu zoyamwitsa, chigoba, zinthu zosungira kutentha, zinthu zoyamwitsa mafuta ndi nsalu yopukutira.

Chifukwa chake, fyuluta ya mpweya wosungunuka imakhala ndi malo akuluakulu komanso ma porosity ambiri (≥75%). Pogwiritsa ntchito mphamvu zambiri zosefera, mankhwalawa amakhala ndi kukana kochepa, kugwira ntchito bwino, fumbi lalikulu ndi zina zotero.

Nsalu zosalukidwa sizimanyowa, zimapuma mosavuta, zimasinthasintha, zimakhala zopepuka, sizimayaka, zimawonongeka mosavuta, sizimawononga, sizimayambitsa kusonkhezera, zimakhala ndi mitundu yosiyanasiyana, zimakhala zotsika mtengo, zimabwezerezedwanso ndi zina zotero. Kapangidwe kameneka kamatenga tinthu ta polypropylene (PP) ngati zopangira, ndipo kamapangidwa mosalekeza ndi kusungunuka kwa kutentha kwambiri, kupopera, kupalasa ndi kukanikiza kotentha.

Nsalu yosalukidwa:

Nsalu yosalukidwa ilibe m'mbali ndi m'mbali, ndi yosavuta kudula ndi kusoka, yolemera pang'ono, mawonekedwe ake ndi osavuta, monga okonda ntchito zamanja.

Popeza ndi nsalu yomwe ingapangidwe popanda kupota, imangofunika kusanthula ndikuwongolera kapena kukonza mwachisawawa ulusi wa nsaluyo kuti ipange kapangidwe ka ukonde wa ulusi, kenako ndikugwiritsa ntchito njira zachikhalidwe zamakaniko, zolumikizira kutentha kapena mankhwala kuti ziyilimbikitse.

Izi sizimapangidwa ndi ulusi wolukidwa, koma polumikiza ulusiwo mwachindunji, kotero kuti mukapeza dzina la kumamatira pa chovalacho, mupeza kuti sichingachotsedwe mu ulusiwo. Nsalu yopanda ulusi yadutsa mu mfundo yachikhalidwe ya nsalu, yokhala ndi njira yochepa, liwiro lopanga mwachangu, kutulutsa kwakukulu, mtengo wotsika, kugwiritsidwa ntchito kwambiri, zipangizo zopangira ndi zina zotero.

Ubale pakati pa nsalu zopanda ulusi ndi nsalu zopota:

Zopanda nsalu zopangidwa ndi ma spunbond ndi zinthu zina zomwe zimagwirizana nazo. Njira zingapo zopangira zinthu zopanda nsalu zimayimiridwa ndi zopanda nsalu zopangidwa ndi ma spunbond, zopanda nsalu zopangidwa ndi spunbond, zopanda nsalu zopangidwa ndi ma spunbond ndi ma spunbond. Makhalidwe ake ndi awa: zopanda nsalu zopangidwa ndi ma spunbond ndi njira yopangira, ndipo ophunzira ambiri pamsika amagwiritsa ntchito zopanda nsalu zopangidwa ndi ma spunbond kuti apange zopanda nsalu.

Nsalu yosalukidwa malinga ndi kapangidwe ka mitundu yosiyanasiyana, polyester, polypropylene, nayiloni, polyurethane, acrylic acid ndi zina zotero. Zigawo zosiyanasiyana zimakhala ndi mitundu yosiyana kwambiri ya nsalu yosalukidwa. Nsalu zosalukidwa nthawi zambiri zimatanthauza zomangira za polyester ndi zomangira za polypropylene. Mitundu ya nsalu ziwirizi ndi yofanana kwambiri ndipo imatha kuzindikirika ndi kutentha kwambiri.

Nsalu yosalukidwa imatanthauza nsalu yomaliza yosalukidwa yomwe imapangidwa pogwiritsa ntchito pepala la polima mwachindunji, ulusi waufupi kapena ulusi wa ulusi wolukidwa kapena kukonza makina, yopindika, yolumikizidwa ndi singano kapena yolimbikitsidwa ndi kutentha.

Zopangidwa ndi ulusi watsopano wofewa, wopumira komanso kapangidwe kake kathyathyathya, sizipanga utoto wonyezimira, zolimba, zokhazikika, zofewa, zabwino ngati silika, zopangidwa ndi nsalu, koma thonje limakhala ndi mawonekedwe ake, poyerekeza ndi matumba osalukidwa a thonje osavuta kupanga, komanso otsika mtengo.

Ubwino:

Kulemera kopepuka: polypropylene synthetic resin monga chinthu chachikulu chomwe chimagwiritsidwa ntchito popanga zinthu zopangira, mphamvu yake ndi 0.9 yokha, magawo atatu mwa asanu a thonje la ku China, lokhala ndi kufewa komanso kumveka bwino.

Yopangidwa ndi ulusi wosalala (2-3D) wosungunuka bwino... Chogulitsidwacho chili ndi kufewa pang'ono komanso chitonthozo.

Choletsa madzi, chopumira: Chip ya polypropylene yosayamwa, palibe chinyezi, mbali yamadzi yomalizidwa, yokhala ndi ma porous, mpweya wabwino wolowera, nsalu youma yosamalika bwino 100 mitundu ya ulusi, yosavuta kutsuka.

Chopanda poizoni, chosakwiyitsa: mankhwalawa akhoza kukhala ofanana ndi zipangizo zopangira chakudya za FDA, alibe zosakaniza zina za mankhwala a ophunzira, magwiridwe antchito ake ndi okhazikika, osapsa, opanda fungo, kapena okwiyitsa khungu.

Mankhwala oletsa tizilombo toyambitsa matenda ndi mankhwala: polypropylene ndi chinthu chopanda mankhwala, osati choboola, chomwe chimatha kusiyanitsa kupezeka kwa mabakiteriya ndi tizilombo tomwe timawonongeka mumadzi; Mankhwala oletsa tizilombo, dzimbiri la alkali, ndi zinthu zomalizidwa sizimakhudza mphamvu ya kuwonongeka.

Mphamvu zotsutsana ndi mabakiteriya: kukoka ndi madzi, nkhungu, mabakiteriya ndi tizilombo ndipo madzi amatha kusiyanitsa kuwonongeka kwa zinthu, kuwonongeka kwa bowa.

Kapangidwe kake kabwino: kopangidwa ndi polypropylene spinning kumatha kufalikira mwachindunji mu netiweki ya mphamvu yolumikizira kutentha, chinthucho chili ndi mphamvu kuposa zinthu zonse za ulusi wamba, mphamvu yake ilibe kolowera, mphamvu yoyima ndi yopingasa komanso yofanana nayo.

Ponena za kuteteza chilengedwe: nsalu zambiri zosalukidwa zimapangidwa ndi polypropylene, pomwe matumba apulasitiki amapangidwa ndi polyethylene. Ngakhale mayina awo ofanana, zinthu ziwirizi zili ndi kapangidwe ka mankhwala kosiyana kwambiri. Kapangidwe ka mankhwala ka polypropylene ndi kokhazikika kwambiri komanso kovuta kusweka, kotero zimatenga zaka 300 kuti matumba apulasitiki asweke. Ndipo kapangidwe ka mankhwala ka polypropylene sikolimba, unyolo wa mamolekyulu ndi wosavuta kusweka, kotero ndikofunikira kuchita kuwonongeka kogwira mtima. Matumba osalukidwa amapitilira ku gawo lotsatira mu mawonekedwe osapha poizoni ndipo amatha kuwola kwathunthu mkati mwa masiku 90. Kuphatikiza apo, matumba osalukidwa amatha kugwiritsidwanso ntchito nthawi zoposa 10, ndipo kuipitsa chilengedwe pambuyo pa zinyalala ndi 10% yokha ya matumba apulasitiki.

Zoyipa:

Nsalu zolukidwa zimakhala zolimba komanso zosalimba poyerekeza ndi nsalu zolukidwa.

Sizingatsukidwe ngati nsalu zina.

Popeza ulusiwo umakonzedwa mbali ina, ndi wosavuta kusweka kuchokera ku ngodya yakumanja, ndi zina zotero. Chifukwa chake, cholinga chachikulu pakukonza njira yopangira ndikukulitsa luso loletsa kugawanika.

Nkhani yomwe ili pamwambapa yakonzedwa ndikufalitsidwa ndi ogulitsa ambiri osalukidwa. Ngati simukumvetsa, takulandirani kuti mutilankhule nafe!
