Nkhani yoti wallpaper ndi yogwirizana ndi chilengedwe yomwe anthu nthawi zambiri amasamala, kunena ndendende, iyenera kukhala: kaya ili ndi formaldehyde kapena nkhani ya mpweya wa formaldehyde. Komabe, ngakhale inki yotengera zosungunulira itagwiritsidwa ntchito pamapepala, musachite mantha chifukwa idzasefukira ndipo sichidzawononganso thupi la munthu. Makamaka pazinthu za PVC, zimasanduka nthunzi mwachangu. Pakhoza kukhala fungo lamphamvu ndi lokwiyitsa mwadzidzidzi, koma n'zosavuta kuthetsa m'masiku ochepa.
Kaya zithunzi zazithunzi ndizogwirizana ndi chilengedwe zimayesedwa potengera mpweya wa VOC
Pakali pano, anthu ambiri samvetsa bwino mfundo yoteteza chilengedwe. Komabe, ndikofunikira kumveketsa bwino nkhaniyi chifukwa pongofotokozera zonse zitha kuyendetsedwa bwino.
Choyamba, kaya zinthuzo zagwiritsa ntchito kwambiri zachilengedwe; Kachiwiri, zinthuzo zimatha kuwonongeka mwachilengedwe (zomwe zimadziwika kuti zowola) zitatayidwa; Apanso, ngati zinthu zimatulutsa mopitirira muyeso ndi mosalekeza VOC pa ntchito, ndipo ngati poizoni zinthu zimatulutsa pa ndondomeko kudzitsitsa.
Pofuna kupititsa patsogolo kulunjika, mfundo yoyamba sidzafotokozedwa apa chifukwa kwenikweni, aliyense sakhudzidwa kwambiri ndi nkhaniyi. Tsopano, chimene chiyenera kutsindika ndi mfundo yachiwiri. Fananizani zopanda nsalu ndi PVC. PVC ndi mankhwala, kupanga utomoni, polima, ndi zotumphukira mankhwala makampani petrochemical. PVC ili ndi pulasitiki yolimba ndipo imagwiritsidwa ntchito kwambiri. Zovala zomwe anthu amavala komanso mbale zapadera ndi zomata za microwave kunyumba zonse zimakhala ndi PVC. Zinthu izi ndizovuta kuzitsitsa m'chilengedwe, ndipo zingatenge mazana kapenanso zaka masauzande kuti athyole unyolo wa polima ndikumaliza kuwononga. Choncho si zinthu zachilengedwe wochezeka.
Mapepala osalukidwa (omwe amadziŵika bwino kuti nsalu yosalukidwa) ndi mtundu wa kuwomba kopanda njira, ndiko kuti, kuluka kosapindika ndi kuluka. Mapangidwe ake ndi otayirira ndipo amatha kuwonongeka mosavuta mwachilengedwe. Chifukwa chake, poyerekeza ndi PVC, ndizochepazinthu zachilengedwe wochezeka.
Kuyerekeza kuyanjana kwa chilengedwe kwa zipangizo ziwirizi kumachokera ku kuchuluka kwa kuipitsa komwe kumayambitsa chilengedwe pambuyo pa kutayidwa kapena kuchuluka kwa mphamvu (kapena zachilengedwe) zomwe zimagwiritsidwa ntchito kuchepetsa zipangizozi.
Komanso, pankhani ya chiyero cha zinthuzo, PVC ili m'gulu la ma polima olemera kwambiri ndipo ndi osavuta; M'malo mwake, zipangizo za nsalu zopanda nsalu zimakhala zosokoneza. Nsalu zosalukidwa ndi njira yoluka, osati nsalu yokha. Zitha kukhala zida zosiyanasiyana zosaluka.
Mfundo yachitatu ndi yokhudzana ndi mpweya wa VOC. VOC=volatile organic compounds=formaldehyde, ether, ethanol, etc. Popeza timakhudzidwa kwambiri ndi formaldehyde, amangotchulidwa kuti formaldehyde emissions.
Kodi izi zili papepala? Zimatengera momwe zinthu zilili. Kodi ndizowona kuti zida zonse zopanda nsalu zilibe VOC, pomwe zida za PVC zili? Ayi, sichoncho.
Pali mtundu wa inki wotchedwa inki yochokera m'madzi, yomwe imagwiritsa ntchito zowonjezera monga madzi ndi ethanol panthawi yojambula, yomwe imakhala yogwirizana kwambiri ndi chilengedwe; Palinso mtundu wa inki wotchedwa solvent based inki (yomwe imadziwika kuti inki yochokera kumafuta), yomwe imagwiritsa ntchito zosungunulira za organic monga zowonjezera pakukongoletsa utoto. Ndi organic organic pawiri yomwe ili ndi formaldehyde ndipo siwokonda zachilengedwe.
Pazinthu za PVC, chifukwa cha mawonekedwe awo owundana, mankhwala afupiafupi monga formaldehyde sangathe kulowa. Chifukwa chake, formaldehyde ndi mankhwala ena amamangiriridwa pamwamba pa zida za PVC ndipo ndizosavuta kusuntha. Patapita masiku angapo, iwo kwenikweni nthunzi nthunzi.
Njira yosinthirayi imatchedwa VOC emissions.
Pazinthu zopanda nsalu, chifukwa cha mawonekedwe ake otayirira, zosungunulira za organic zimatha kulowa muzinthuzo, ndipo njira ya volatilization yamagulu monga formaldehyde imakhala yocheperako. Kwa opanga ambiri, makamaka mitundu yayikulu, inki yamtundu wa zosungunulira sagwiritsidwa ntchito kawirikawiri. Ngakhale zitagwiritsidwa ntchito, maulalo owonjezera adzawonjezedwa popanga kuti amalize kutulutsa VOC.
M'malo mwake, pokongoletsa nyumba, chinthu chowopedwa kwambiri sizithunzi, koma mapanelo ophatikizika (osati matabwa olimba). Chifukwa kutulutsa kwa VOC kuchokera pamapanelo ophatikizika kumakhala pang'onopang'ono, kumatenga miyezi ingapo kapena zaka.
Pafupifupi zithunzi zonse zowoneka bwino kwambiri si nsalu zosalukidwa
Zomwe zikuchitika panopa ndikuti ogulitsa ambiri ndi eni ake a masitolo apadera adzanena kuti nsalu zopanda nsalu ndizo zokonda kwambiri zachilengedwe. Ndikuwona izi zachilendo. N’chifukwa chiyani tiyenera kunena zimenezi? Kodi simukumvetsetsa? Kapena mukuwopa kuti makasitomala atha kuluza bizinesi polimbikitsidwa ndi malingaliro otere ndi masitolo ena azithunzi?
Kapena Palibe wa iwo! Chinsinsi chake ndi chakuti zida zopangira mapepala osakhala opangidwa ndi nsalu sizokwera mtengo, ndondomekoyi ndi yosavuta, ndipo malonda amatha kugulitsidwa pamtengo wapamwamba. Phindu lalikulu lili pano.
Sindikudziwa maiko ena, koma palibe chodabwitsa ku Europe. M'malo mwake, pafupifupi mitundu yonse yayikulu padziko lapansi, kaya ndi Marburg, Aishi, Zhanbai Mansion, kapena zithunzi zapamwamba kwambiri, zimapangidwa ndi nsalu ya PVC. Pakati pawo, mapepala amapepala a holo yowonetsera ku Italy ali ndi PVC yozama kwambiri.
Tsopano zikuwoneka kuti mwina dziko lathu lokha ndilokondwa kwambiri ndi mapepala opanda nsalu padziko lapansi, chifukwa m'zaka zingapo zapitazi, masitolo akuluakulu agwiritsira ntchito pang'onopang'ono zikwama zopanda nsalu m'malo mwa matumba apulasitiki, ndipo matumba omwe si opangidwa ndi nsalu ndi okonda zachilengedwe. Zowona: Zosalukidwa ndizogwirizana ndi chilengedwe. Kuteteza chilengedwe ndikofunikira, koma kutulutsa kwa formaldehyde sikudetsa nkhawa.
Opanga zapakhomo amakonda kupanga ndi kugulitsa nsalu zosalukidwa, koma pali zovuta zokhudzana ndi luso laukadaulo ndi zinthu zomwe zimayendetsedwa ndi phindu.
Nsalu zosalukidwa ndizoyenera pamlingo wamakono wamakono opanga zoweta (palibe chodzigudubuza chomwe chimafunikira, chosindikizira chosindikizira chimagwiritsidwa ntchito. PVC pamwamba imafuna embossing roller yakuya komanso yozama, ndipo mtengo wa embossing roller ndi wokwera. Mtengo wopangira laser engraving embossing roller imayamba pa yuanraving ku Italy ndi 2000 ngakhale mtengo wokwera kwambiri ku Italy ndi 2000. Germany, chodzigudubuza chojambula pamanja nthawi zambiri chimawononga ma euro masauzande angapo, chomwe ndi chokongola kwambiri ndipo ndi ntchito yaluso.). Pachifukwa ichi, mapepala apamwamba a PVC apamwamba amafunikira ndalama zambiri zam'tsogolo.
Ngati kuzindikira kwa msika sikuli kwakukulu, ndalama za embossing rollers zidzawonongeka, zomwe zimabweretsa chiopsezo chachikulu. Chogudubuza chosindikizira chomwe chimagwiritsidwa ntchito pansalu zosalukidwa chimangowononga ndalama zoposa chikwi chimodzi, ndi ndalama zochepa komanso zotsatira zachangu. Sichisoni kuchitaya ukalephera. Choncho opanga m'nyumba ali okonzeka kwambiri kupanga mapepala osakhala ndi nsalu. Zikuwoneka kuti zikutsatira mosamalitsa ndondomeko ya ntchito ya fakitale "yachidule, yosalala, komanso yachangu".
Pamenepo,zinthu zosalukidwakukhala ndi zolakwika ziwiri zazikulu: choyamba, nthawi zonse pamakhala kusinthasintha pang'ono mu utoto, chifukwa pamwamba pa zinthu zopanda nsalu sizili wandiweyani mokwanira, ndipo mtunduwo uyenera kulowa. Kachiwiri, ngati inki yopangidwa ndi mafuta ikugwiritsidwa ntchito, zowonjezera za inki yopangidwa ndi mafuta zidzalowa mu nsalu zopanda nsalu, zomwe zimapangitsa kuti zikhale zovuta kumasula formaldehyde.
