PVC khomo nsalu yotchinga zaka ziwiri osati chikasu mfundo

Chophimba cha pakhomo chimagwiritsidwa ntchito ndi banja lililonse, makamaka m'chilimwe chotentha, udzudzu umakhala wochuluka, kuwala kumakhalanso kolimba kwambiri, kotero m'nyengo ya chilimwe malonda a nsalu yotchinga ndi yowongoka, khalidwe la mankhwala ndi chitsimikizo chofunikira.Pali mitundu yambiri ya masitaelo a makatani apakhomo.M'chilimwe, nthawi zambiri timawona nsalu yofewa ya PVC.PVC curtain 微信图片_202203151152073konse, mandala chitseko nsalu yotchinga ali ndi vuto ndi wamba, ndiko kuti, n'zosavuta chikasu, kukalamba mwamsanga, ndipo kwambiri amakhudza maonekedwe a mankhwala, kuonekera ngati chodabwitsa angalole wosuta mutu, zambiri tiyeni zofewa chitseko wopanga chopanda chothandiza.Opanga ambiri akhala akuyang'ana wothandizira kuti asinthe vutoli, adayesanso zambiri, ena atatha kugwiritsa ntchito ngakhale atasintha, koma zotsatira zake si zabwino.

Chifukwa cha ichi ndi chakuti nsalu yotchinga ya PVC ndi yachikasu, makamaka chifukwa nsalu yotchinga pakhomo imakhala panja, dzuwa likhoza kuunikira, nthawi zambiri miyezi itatu kapena kuposerapo idzawoneka yachikasu, yachikasu yayitali kwambiri.Chodabwitsa ichi makamaka chifukwa cheza ultraviolet padzuwa, amene anawononga maselo dongosolo la PVC nsalu yotchinga, kuti polar chlorine zili PVC dongosolo mu kuwala kwa nthawi yaitali ndi makutidwe ndi okosijeni imathandizira kuwonongeka kwa chikasu mofanana ndi PS ndi PU.Izi zitha kuchepetsedwa powonjezera kachulukidwe kakang'ono ka antioxidants ndi zowongolera zopepuka panthawi yophatikiza.Zowonjezera zowonjezera za Antioxidants 1010 ndi UV-531 ndizophatikiza zotsutsana ndi ukalamba zophatikizika za PVC.Chonde onani.

Komabe, zinthu zowoneka bwino za PVC zotchinga nthawi zambiri zimakhala zosagwirizana ndi cheza cha ultraviolet kuposa zofunikira za antioxidant, tikulimbikitsidwa kuti mitundu yosiyanasiyana ya ma stabilizer omwe amagwiritsidwa ntchito polumikizana ndi yabwino.Ambiri mwa UV absorbers pamsika ndi monomer, ndipo sangathe kusewera kwambiri odana ndi chikasu zotsatira.Ayenera kusankha kuyamwa Mipikisano nsonga UV kuyamwa, akhoza zoonekeratu kukwaniritsa yaitali sanali chikasu kwenikweni.Pakadali pano, msika umakonda kugwiritsa ntchito mtundu wabwino wa machesi a UV absorber X-2, amangokwaniritsa zomwe makasitomala amafuna.Kusankha kwa anti-oxygen wotere, anti-ultraviolet, kukhazikika kopepuka kwa machesi amtundu wa UV, kumatha kuperekeza zinthu zamapulasitiki.
