Kuyesa ndi masitepe ogwiritsira ntchito kupuma kwa nsalu zopanda nsalu

Kupuma bwino ndi chimodzi mwazifukwa zofunika zomwe zimagwiritsidwa ntchito kwambiri. Kutenga mankhwala okhudzana ndi mankhwala a zachipatala monga chitsanzo, ngati kupuma kwa nsalu zopanda nsalu kuli koipa, pulasitala yomwe imapangidwa kuchokera pamenepo sidzatha kukumana ndi kupuma kwabwino kwa khungu, zomwe zimapangitsa kuti munthu asamawonongeke; Kusapumira bwino kwa matepi omatira achipatala monga zida zothandizira kungayambitse kukula kwa tizilombo toyambitsa matenda pafupi ndi bala, zomwe zimayambitsa matenda a bala; Kusapuma bwino kwa zovala zoteteza kumatha kukhudza kwambiri chitonthozo chake chikavala. Kupuma ndi chimodzi mwazinthu zabwino kwambiri zazipangizo zopanda nsalu, chomwe ndi chinthu chofunikira chomwe chimakhudza chitetezo, ukhondo, chitonthozo ndi ntchito zina za zinthu zopanda nsalu.

Kuyesa Kupuma kwa Nsalu Zosalukidwa

Kupuma ndikutha kwa mpweya kudutsa mu chitsanzo, ndipo kuyesa kungathe kutengera njira yokhazikika ya GB/T 5453-1997 "Kutsimikiza kwa Kupuma kwa Nsalu Zovala". Mulingo uwu umagwira ntchito pansalu zosiyanasiyana, kuphatikiza nsalu zamakampani, nsalu zosalukidwa, ndi zinthu zina zopumira. Zipangizozi zimagwiritsa ntchito choyezera mpweya cha GTR-704R chodzipanga pawokha ndikupangidwa ndi Jinan Sike Testing Technology Co., Ltd. Zida ntchito ndi yosavuta komanso yabwino; Kuyesera kongodina kamodzi, kuyesa kokhazikika. Ingokonzani chitsanzo chansalu chosalukidwa chomwe chikuyesedwa pa chipangizocho, yatsani chidacho, ndikuyika magawo oyesera. Ingodinani pang'ono kuti mutsegule mawonekedwe a automatic ndikudina kamodzi kokha.

Njira zogwirira ntchito

1. Dulani mwachisawawa zitsanzo 10 ndi mainchesi a 50 mm kuchokera pamwamba pa zitsanzo za nsalu zopanda nsalu.

2. Tengani imodzi mwa zitsanzo ndikuyiyika mu tester permeability tester kuti chitsanzocho chikhale chophwanyika, popanda deformation, ndi kusindikiza bwino mbali zonse za chitsanzo.

3. Khazikitsani kusiyana kwa kupanikizika kumbali zonse ziwiri za chitsanzo molingana ndi mpweya wake wa mpweya kapena zofunikira zoyenera. Kusiyanitsa kwapakati pa mayesowa ndi 100 Pa. Sinthani valavu yoyendetsera mphamvu ndikusintha kusiyana kwapakati pa mbali zonse za chitsanzo. Pamene kusiyana kwapanikizi kumafika pamtengo wokhazikitsidwa, mayesero amasiya. Chipangizochi chimangowonetsa kuchuluka kwa gasi komwe kumadutsa pachitsanzo panthawiyi.

4. Bwerezani chitsanzo chotsitsa ndi kusintha kwa valve kusintha ndondomeko mpaka kuyesa kwa zitsanzo za 10 kutha.

Kusapumira kosakwanira kwa zinthu zopanda nsalu kumatha kubweretsanso zovuta zambiri pakugwiritsa ntchito kwawo. Chifukwa chake, kulimbikitsa kuyesa kupuma kwa nsalu zosalukidwa ndi imodzi mwazinthu zofunika kuwonetsetsa kuti zinthu zokhudzana ndi zomwe zimapangidwa zimakwaniritsa zofunikira zogwiritsidwa ntchito.

Kupuma kwa nsalu zopanda nsalu

Kupuma kwa nsalu zopanda nsalu kumadalira kuchuluka kwake kwa fiber ndi katundu wa nsalu. Ulusi wowongoka bwino, mpweya wabwino, ndi katundu wochepa wa nsalu, ndi bwino kupuma. Kuphatikiza apo, kupuma kwa nsalu zopanda nsalu kumagwirizananso ndi zinthu monga njira yake yopangira komanso njira yoluka zinthu.

Momwe mungaphatikizire ntchito yopanda madzi komanso yopumira?

Nthawi zambiri, kutsekereza madzi ndi kupuma nthawi zambiri kumatsutsana. Momwe mungasamalire kutsekereza madzi ndi kupuma ndi mutu wotchuka wofufuza. Masiku ano, zinthu zopangidwa ndi nsalu zopanda nsalu nthawi zambiri zimagwiritsa ntchito njira yophatikizira yamitundu ingapo, kuti ikwaniritse bwino pakati pa kutsekereza madzi ndi kupuma kudzera mumitundu yosiyanasiyana ya ulusi ndi kuphatikiza kwa zinthu.

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.
