Chilimwe chinafika, kodi nsalu yofewa ya PVC imaletsa bwanji kukalamba?

Kukutentha kwambiri, ndipo pafupifupi nthawi yachilimwe, ndipo atsikana avala kale zoteteza ku dzuwa kuti atetezere khungu lawo ku cheza choopsa chadzuwa.Mofananamo, kwa opanga ambiri, ndikofunikira kukonzekera tsiku lamvula, pazogulitsa zawo kuti ateteze, monga awo, lero tikukamba za momwe tingatetezere nsalu yofewa.Chophimba chofewa cha PVC ndi chinthu chomwe aliyense amatha kuwona kulikonse.Ndi chitukuko cha anthu, mitundu yosiyanasiyana ya mandala PVC chitseko nsalu yotchinga anaonekera, monga: mandala PVC pulasitiki khomo mthunzi, tizilombo-umboni khomo mthunzi, fumbi umboni khomo mthunzi, odana malo amodzi khomo mthunzi, ozizira-umboni khomo mthunzi, otsika kutentha-umboni khomo mthunzi, odana ndi ultraviolet ray chitseko mthunzi, mandala PVC zofewa bolodi, basi mwamsanga mpukutu chitseko, mwamsanga mpukutu chitseko, PVC fumbi umboni chitseko mthunzi, PVC zofewa mphira mthunzi, mandala zofewa khomo mthunzi, odana ndi malo amodzi gululi mthunzi, pulasitiki PVC mphira mthunzi, PVC pulasitiki khomo mthunzi, pulasitiki mandala chitseko mthunzi, etc. .Chophimba chofewa chowoneka bwino chopangidwa ndi PVC chimazizira, chimatentha, chimapulumutsa mphamvu komanso chimateteza mpweya wozizira komanso wotentha.Tizilombo, fumbi, mphepo, chinyezi, moto, magetsi osasunthika, anti-glare, anti-uv, kutchinjiriza mawu, kuwala kwa masana, chenjezo lachitetezo, kupewa ngozi.Zogwiritsidwa ntchito posungirako kuzizira, chakudya, mankhwala, mankhwala, nsalu, zamagetsi, makina, kusindikiza, mafakitale, malo ogwirira ntchito, zipatala, misika, malo odyera ndi mafakitale ena kulikonse.Mutha kunena kuti ili ndi mapulogalamu ambiri.

Ndiye tingatani kuti chinsalu cha pakhomo chisachite chikasu ndi kusinthika kwa nthawi yayitali?Tiyenera kudziwa chomwe chimayambitsa chikasu.Kafukufuku akuwonetsa kuti kukalamba kwa ma polima mumlengalenga kumachitika makamaka chifukwa cha kuwonongeka kwa photooxidation ya ma polima ndi cheza cha ultraviolet komanso ndi mpweya, pvc Curtain, waya ndi chingwe, filimu yaulimi ndi zinthu zina zakunja ziyenera kulabadira kwambiri.Malingana ndi quantum mechanics, mphamvu ya photon imodzi imakhala yosiyana mosiyana ndi kutalika kwa mafunde, ndipo kufupi ndi kutalika kwa mafunde kumakwera mphamvu.Ngakhale mphamvu ya kuwala kwa ultraviolet imangotengera 5% ya kuwala kwa dzuwa, kutalika kwake ndi kochepa kwambiri, ndipo mphamvu imodzi ya photon ndiyopamwamba kwambiri, pafupifupi 290 ~ 390 KJ/MOL.Mphamvu ya mgwirizano wa pawiri nthawi zambiri 290 ~ 400 Kj / mol, yomwe ili pafupi ndi mphamvu ya ultraviolet ray ndipo imawonongeka mosavuta ndi ultraviolet ray, ichi ndi chifukwa chachikulu chomwe chophimba cha PVC chimakhala chosavuta kupanga photoaging.Pa ukalamba ndondomeko ufulu ankafuna kusintha zinthu mopitirira ndi hydroperoxide amapangidwa, macromolecule unyolo wosweka ndi mtanda zogwirizana, ndipo potsiriza mankhwala amataya ntchito yake.

Uv Absorber imatha kuletsa bwino kuwonongeka kwa UV kuzinthu, kuti muchepetse kuwonongeka kwazinthu ndikukulitsa moyo wautumiki wa ma polima.LR-ZW-1 yopangidwa ndi Henan Longrui Chemical Co., Ltd. imatha kuyamwa mwamphamvu 270 ~ 400nm UV, mphamvu yotengedwa imatulutsidwa kapena kugwiritsidwa ntchito ngati mphamvu ya kutentha kapena ma radiation opanda mphamvu opanda mphamvu, kuti ateteze mphamvu ya UV yomwe imatengedwa ndi Chromophore ya nsalu yotchinga ya PVC kuti isasangalale.Limbikitsani moyo wautumiki wa nsalu yotchinga, mochedwa osati chikasu chophweka, komanso sichikhudza kuwonekera, chofunika kwambiri ndikuwonjezera pang'ono, kupulumutsa mtengo wa opanga.
