Ka-hortagga ultraviolet-ka deegaanka (UV) ee dhar aan tolka lahayn

Dharka UV ee aan tolka lahayn waxay ku gaadhaan ilaalin hufan UV iyada oo loo marayo wax ka beddelka walxaha (nano oxides, graphene) waxaana si weyn loogu isticmaalaa beeraha, dhismaha, iyo goobaha caafimaadka.

Mabaadi'da farsamada iyo hababka wax soo saarka

wax lagu daro UV u adkaysta

Buuxiyeyaasha aan orgaaniga ahayn: nano zinc oxide (ZnO), graphene oxide, iwm., waxay ku gaadhaan ilaalinta iyagoo nuugaya ama ka tarjumaya iftiinka ultraviolet. Dahaarka Graphene oxide wuxuu yarayn karaa gudbinta dharka aan toliyaha ahayn wax ka yar 4% ee band UVA (320-400 nm), oo leh iskudar ilaalinta UV (UPF) oo ka weyn 30, iyadoo la ilaalinayo hoos u dhigista gudbinta iftiinka ee kaliya 30-50%.

Farsamaynta farsamaynta ee shaqaynaysa

Tignoolajiyada Spunbond, polypropylene (PP) waxay si toos ah u sameysan tahay shabakad ka dib marka la dhalaalayo, iyo 3-4.5% anti UV masterbatch ayaa lagu daraa si loo gaaro ilaalin isku mid ah.

Meelaha ugu muhiimsan ee codsiga

Beeraha

Ilaalinta dalagyada: Daboolida dhulka ama dhirta si looga hortago dhaxan iyo cayayaanka, dheellitirka iftiinka iyo hawada (gudbinta iftiinka 50-70%), kor u qaadida korriinka xasilloon; Shuruudaha adkeysiga: ku dar wakiilka gabowga ka-hortagga si loo kordhiyo nolosha adeegga dibadda (qeexidda caadiga ah: 80 - 150 gsm, ballac ilaa 4.5 mitir).

Goobta dhismaha

Duubista walxaha dahaarka: lagu duudduubay lakabyada dahaarka sida dhogorta dhalada si looga hortago faafinta fiber-ka iyo xannibaadda waxyeelada UV, kordhinta nolosha qalabka dhismaha; Ilaalinta Injineeriyada: Waxaa loo isticmaalaa daawaynta sibidhka, laamiyada gogosha, nooca dab-demiska ee la habeeyey (is-deminta ka dib dabka) ama nooca xajinta sare (dhuuban 0.3-1.3mm).

Ilaalinta caafimaadka iyo qofka

Ka-hortagga bakteeriyada iyo UV-ga isku-dhafka ah: Ag ZnO isku-dhafka ah ayaa lagu daraa si loo dhalaaliyo dhar aan-dhogorta lahayn si loo gaaro 99% heerka bakteeriyada bakteeriyada iyo dib-u-dhaca ololka (tusaha oksijiinta 31.6%, heerka UL94 V-0), oo loo isticmaalo maaskaro iyo dharka qalliinka; Alaabooyinka nadaafadda: xafaayadda, masaxarada qoyan, iwm. waxay ka faa'iidaystaan ​​sifooyinkooda bakteeriyada iyo neefsashada.

Alaabta dibadda

Tarpaulin, dharka ilaalinta, muraayadaha UV, iwm., dheellitiraya qiimaha UPF ee khafiifka ah iyo kan sare.

Faa'iidooyinka waxqabadka

La qabsiga deegaanka

Asiidh heer sare ah iyo iska caabin alkali ah, iska caabin dareere ah, oo ku habboon bay'ada adag. Qalabka PP ee la dumin karo (sida 100% polypropylene bikrad ah) waxay la socdaan isbeddellada deegaanka.

Is dhexgalka shaqada badan

Waxqabadyo badan oo isku jira sida olol dib-u-dhigis, bakteeriyada, biyuhu-ilaamiska iyo boodhka (sida Ag ZnO+ fidinta ololka dib-u-dhigista). Dabacsanaan wanaagsan, dahaarka ma dillaacin ka dib foorarsi soo noqnoqda.

Dhaqaale

Qiimo jaban (sida dhar-dhoobo-beeraha oo aan tolnayn ilaa $1.4-2.1/kg), wax-soo-saarka la beddeli karo.
