Environmental Ultraviolet protection (UV) nonwoven nsalu

Nsalu za UV zosalukidwa zimapeza chitetezo chokwanira cha UV kudzera mukusintha kwazinthu (nano oxides, graphene) ndipo zimagwiritsidwa ntchito kwambiri paulimi, zomangamanga, ndi zamankhwala.

Mfundo zaukadaulo ndi njira zopangira

Chowonjezera chosagwirizana ndi UV

Ma Inorganic fillers: nano zinc oxide (ZnO), graphene oxide, ndi zina zotero, amapeza chitetezo poyamwa kapena kuwunikira kuwala kwa ultraviolet. Graphene oxide ❖ kuyanika akhoza kuchepetsa transmittance wa nsalu sanali nsalu zosakwana 4% mu gulu UVA (320-400 nm), ndi UV chitetezo koyenerera (UPF) kuposa 30, pamene kukhalabe looneka transmittance kuchepetsa 30-50% yokha.

Ukadaulo waukadaulo wogwira ntchito

Ukadaulo wa Spunbond, polypropylene (PP) umapangidwa mwachindunji mu ukonde pambuyo popopera mbewu mankhwalawa, ndipo 3-4.5% anti UV masterbatch amawonjezedwa kuti atetezedwe yunifolomu.

Magawo akuluakulu ofunsira

Ulimi

Chitetezo cha mbewu: Kuphimba nthaka kapena zomera kuti zisawonongeke ndi chisanu ndi tizirombo, kusanja kuwala ndi mpweya wodutsa (kutumiza kuwala 50-70%), kulimbikitsa kukula kokhazikika; Zofunikira zokhalitsa: onjezani wothandizira oletsa kukalamba kuti awonjezere moyo wantchito wakunja (zodziwika bwino: 80 - 150 gsm, m'lifupi mpaka 4.5 metres).

Ntchito yomanga

Kukulunga kwazinthu zodziyimira payokha: wokutidwa ndi zigawo zotchinjiriza monga ubweya wagalasi kuti muteteze kufalikira kwa ulusi ndikutchinga kuwonongeka kwa UV, kukulitsa moyo wa zida zomangira; Chitetezo chaumisiri: Amagwiritsidwa ntchito pochiritsa simenti, kuyatsa misewu, mtundu wamoto wozimitsa moto (wozimitsa wokha utachoka pamoto) kapena kulimba kwambiri (kukhuthala 0.3-1.3mm).

Chitetezo chamankhwala ndi chaumwini

Gulu lolimbana ndi mabakiteriya ndi UV: Gulu la Ag ZnO limawonjezedwa kuti lisungunuke nsalu zosalukidwa kuti zikwaniritse 99% antibacterial rate ndi retardancy yamoto (oxygen index 31.6%, UL94 V-0 level), yogwiritsidwa ntchito ngati masks ndi mikanjo ya opaleshoni; Ukhondo mankhwala: Matewera, chonyowa zopukuta, etc. ntchito antibacterial ndi mpweya katundu.

Zogulitsa zakunja

Tarpaulin, zovala zodzitchinjiriza, mazenera a UV screen, etc., kusanja mopepuka komanso mtengo wapamwamba wa UPF.

Ubwino wamachitidwe

Kusinthasintha kwa chilengedwe

Zabwino kwambiri za asidi ndi kukana kwa alkali, kukana zosungunulira, zoyenera madera ovuta. Zida zowonongeka za PP (monga 100% virgin polypropylene) zimagwirizana ndi zochitika zachilengedwe.

Kuphatikiza kwazinthu zambiri

Zophatikizika zingapo zogwira ntchito monga choletsa moto, antibacterial, madzi komanso fumbi (monga Ag ZnO + expansion flame retardant synergistic). Kusinthasintha kwabwino, zokutira sizimachoka pambuyo popindika mobwerezabwereza.

Zachuma

Mtengo wotsika (monga nsalu zaulimi zosalukidwa pafupifupi $1.4-2.1/kg), kupanga makonda.
