Kodi mphamvu ya nsalu yopanda nsalu yachipatala ndi yotani?

Nsalu zachipatala zopanda nsalu zimagwiritsidwa ntchito kwambiri pochita zachipatala. Monga mtundu watsopano wazolongedza zakuthupi, ndi oyenera kuthamanga nthunzi yotseketsa ndi ethylene oxide yotseketsa. Lili ndi mphamvu yochedwa lawi ndipo ilibe magetsi osasunthika. Chifukwa cha kufooka kwake kwa misozi komanso kuonda kwake, ndiyoyenera kulongedza zida zopepuka komanso zopanda lakuthwa. Zilibe zinthu zapoizoni, sizimakwiyitsa, zimakhala ndi hydrophobicity yabwino, ndipo sizosavuta kuyambitsa chinyezi mukamagwiritsa ntchito. Ili ndi mawonekedwe apadera kuti asawonongeke ndipo imakhala ndi moyo wa alumali wa masiku 180 mutatha kutsekereza.

Mphamvu yamankhwala sanali nsalu nsalundi chimodzi mwa zizindikiro zofunika powunika momwe ntchito yake ikuyendera, yomwe imakhudza mwachindunji mphamvu yake ndi chitetezo pazachipatala. Kulimba kwa nsalu zosalukidwa zachipatala kumawonekera makamaka pazinthu izi:

Tanthauzo la mphamvu ndi magulu

Mphamvu ya mankhwala sanali nsalu nsalu zambiri kumaphatikizapo kumangika mphamvu, misozi mphamvu, fracture mphamvu, etc. Zizindikiro izi kuyeza luso la nsalu sanali nsalu kukana kuwonongeka pamene pansi mphamvu kunja.

Zinthu zomwe zimakhudza mphamvu

Kulemera kwake:

Kwa nsalu zopanda nsalu zopangidwa pamzere womwewo wopangira, kulemera kwake kumakhala kokulirapo, kumakhala kolimba komanso kokulirapo, komanso kuwonjezereka kofananira kwamphamvu. Mwachitsanzo, 60 magalamu a nsalu zopanda nsalu ndizovuta ndipo zimakhala ndi mphamvu kuposa magalamu 50 a nsalu zopanda nsalu.

Njira yopangira ndi zida:

Njira zosiyanasiyana zopangira zinthu komanso kuchuluka kwazinthu zimakhudza kwambiri kulimba kwa nsalu zopanda nsalu. Mwachitsanzo, poyerekeza ndi kamangidwe ka SMMMS (spunbond layer + meltblown layer + spunbond), kamangidwe ka SMS (spunbond layer + meltblown layer + meltblown layer + spunbond) kamangidwe kakhoza kukhala ndi mphamvu yogwira ntchito bwino pazinthu zina chifukwa chowonjezera chowonjezera cha meltblown. Kuphatikiza apo, kugwiritsa ntchito ulusi wabwino kwambiri komanso zida zapamwamba kwambiri zopangira zimathanso kukulitsa mphamvu za nsalu zosalukidwa.

Miyezo yoyesera:

Kuyesa kwamphamvu kwa nsalu zosalukidwa zachipatala kuyenera kutsata miyezo yoyenera yadziko ndi mafakitale, monga standard standard GB/T 19679-2005 "Zida Zachipatala Zosalukidwa", yomwe imatchula zizindikiro zazikulu zogwirira ntchito monga mphamvu ya nsalu zopanda nsalu.

Njira yoyesera mphamvu

Kuyesa kwamphamvu kwa nsalu zopanda nsalu zachipatala kumachitika makamaka kudzera pamakina oyesera olimba, omwe amatha kugwiritsa ntchito zolemetsa ndikuyesa kulimba kwamphamvu, kutalika ndi zizindikiro zina za nsalu zopanda nsalu. Pakuyesa, zitsanzo zoyimira ziyenera kusankhidwa ndikudulidwa mumiyeso yoyenera musanayike pakati pa zida zapamwamba ndi zotsika zamakina oyesera kuti ayesedwe.

Kuchita mwamphamvu

Nsalu zachipatala zopanda nsalu nthawi zambiri zimagwira ntchito bwino pa mphamvu ndipo zimatha kukwaniritsa zosowa zapadera zachipatala. Mwachitsanzo, nsalu zopanda nsalu zomwe zimagwiritsidwa ntchito ponyamula zida zopangira opaleshoni ziyenera kukhala ndi mphamvu zambiri kuti zitsimikizire kuti sizidzawonongeka panthawi yoyendetsa ndi kusungirako; Nsalu zopanda nsalu zomwe zimagwiritsidwa ntchito povala mabala zimafunika kukhala ndi mlingo winawake wa kusinthasintha ndi mphamvu zowonongeka kuti zigwirizane ndi bala ndikusunga bata.

Chidule

Mwachidule, mphamvu ya nsalu yopanda nsalu yachipatala ndi chizindikiro chokwanira cha ntchito chomwe chimakhudzidwa ndi zinthu zosiyanasiyana monga kulemera, kupanga ndi zipangizo, ndi miyezo yoyesera. Pakugwiritsa ntchito, Lei ayenera kusankha zinthu zoyenera zachipatala zosalukidwa kutengera momwe amagwiritsidwira ntchito komanso zofunikira. Pakadali pano, kuyezetsa kolimba komanso kuwongolera bwino ndikofunikiranso kuti zitsimikizire kulimba ndi chitetezo chazinthu zamankhwala zopanda nsalu.

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 ku 9 magalamu mpaka 300 magalamu.
