Kodi mungasankhe bwanji uve?

Munkhaniyi, timalankhula za mfundo zazikuluzikulu za polimer anti-UV kusankha, akuyembekeza kuti akulimbikitseni. Kuyika kwa Polymer ndikofanana ndi makina otenthetsera mafuta, mphamvu zakunja zonse zimaukira unyolo, ndipo madongosolo akunja ndiwovuta monga kusintha kwapata kwa polymer, kutsika katundu.

Polimer anti-UV Nthawi zambiri amayamba kuchokera pazinthu ziwiri: imodzi ndikuvala zovala za dzuwa, onjezerani zinthu zina mwa mitundu ya ma radiation kudzera pa intramulecular kuti amasulidwe, potero kuteteza polymer. Lachiwiri ndikutanthauzira polymer, magulu ena a polymer asangalala ndi UV, chifukwa cha ma radicals osinthika (ma hals) kuti atengere ma radical (kuti apewe kuwonongeka kwambiri kwa polymer.

Onse okalamba, okalamba a UV ayenera kuganizira zinthu 7, monga tsambali.

1)Magwiridwe - Kukhazikika:

UVA utakhala wowala kwa nthawi yayitali, kapangidwe kake ka mankhwala kwake kumasintha kutha kwamuyaya, kutaya zowona za ultraviolet, zomwe zimatchedwa chithunzi cha UVA. Pakati pawo, Triazine Uva (monga yiho uva uva1064 / 1577, etc.) ndiye mtundu wokhala ndi moyo wautali kwambiri, motero ndi koyenera kugwiritsa ntchito njira zina zomwe zimafunikira kukana kwa nyengo. Zachidziwikire, kugwiritsa ntchito kwa Benzotrianoles wamba (monga yiho uv234 / 531, etc.) kapena benzophenone gwiritsani ntchito bwino.

2)Magwiridwe - utoto ndi zinthu zakuthupi zimasungidwa

Ngati mungayang'ane kutetezedwa ndi chinthucho, zotsatira za Hales ndizodziwikiratu (hales sizifunikira kulingalira za mphamvu), pamakhala pabwino kuti izi zitheke.

3)Mawonekedwe - mtundu woyamba

UVA amatenga kuwala kwa ultraviolet, komanso kumatenga kuwala kwakanthawi kochepa kwambiri, ndikupangitsa mtundu woyamba kukhala wachikasu. Zofunsira ndi zofuna za utoto woyambira kwambiri, zojambula zokhudzana ndi UV ndizabwino ndizabwino.

4)Makulidwe:

UVA pamafunika makulidwe ena kuti agwire ntchito (lamulo la Bill Ranbier), ndipo 120 safunikira kuganizira vuto ili, kotero 70% ya 120% imagwiritsidwa ntchito mumitundu yochepa monga filimuyo, silika, ndi utoto. Tiyeneranso kuganizira za nkhaniyi posankha ma pulasitiki ozunzidwa. Nthawi yomweyo, makulidwe amakhudzanso kusankha kwa ma hals, ndipo nthawi zambiri amasankha ma hals ang'onoang'ono olemera.

5)Kugwirizana ndi Tsoka:

Zowonjezera sizigwirizana ndi utomoni, ndipo mpweya wake umakhala wosawoneka bwino monga chisanu, komanso kutaya zinthu zoteteza.

Kwa TPU, yomwe imagwirizana kwenikweni ndi zowonjezera, yihoo polymet yapanga njira ya ultraviolet ya ultraviolet, yomwe imawonjezereka pa ma polyrethane unyolo, kuthetsa vuto la mpweya.

6)Kugwirizana ndi njira yonse:

Ponena za kuphatikizidwa, chinthu choyamba ndi chamoyo komanso challianity. Monga Amine Amine, Hales amawonetsa acidity osiyanasiyana ndi alkalinity, ndipo ma hals wamba acidity ndi alkality ali motere (PKB ndi yaying'ono komanso yalkaline):

Ena amalima kapena zowonjezera ndi acidic, choncho pewani kuwonjezera ma alkaline owonjezera matebulo.

7)Zofunikira Zapadera: Kuwonekera, Kuletsa Kuletsa:

Pomaliza, timalankhula za mavuto ocheperako a UV: woyamba ndi wowoneka bwino uV, zakumwa zina zogwirira ntchito carotene.

Chachiwiri ndi chosinthika chosinthika, kuchotsa madzi ndi kofala kwambiri kwa hales (monga utoto wagalimoto), ndiye kuti zinthu zambiri pamsika ndizofanana. Komabe, zokutira zina kapena zinthu zapulasitiki zomwe zimafuna kuthana ndi nyengo idzakumana ndi ma sol solformant kwa nthawi yayitali, ndipo sichovuta kukana ma solvent, omwe amalephera kutsuka kwa ma alkalin. Zomwe zili pamwambazi ndi mfundo 7 zathu pakusankhidwa kwa zowonjezera za UV, kugwiritsa ntchito nthawi zina kumakhala kovuta, nthawi zina muyenera kudziwa, ndipo nthawi zina muyenera kuchita ndi inu, kuthetsa mavuto limodzi, ndikulimbana.

Qingdao yihoo polymer Technologlognolognology Co., Ltd.amadzipereka kunyamula zoyatsira kwambiri, ma antioxidarants, lawi lamoto ndi zinthu zina, zolandiridwa kuti mulumikizane ndi nthawi iliyonse:yihoo@yihoopolymer.com
