Iyo nyaya yekuti Wallpaper ine hushamwari kwezvakatipoteredza iyo vanhu vanowanzo funga nezvayo, kutaura chokwadi, inofanira kunge iri: ingave ine formaldehyde kana nyaya yekubuda kwe formaldehyde. Nekudaro, kunyangwe kana inki inonyungudutsa ikashandiswa mumadziro, usatya nekuti inobuda uye isingachakonzerese kukuvadza kumuviri wemunhu. Kunyanya zvePVC zvinhu, zvinoputika nekukurumidza. Panogona kuva nekunhuhwirira kwakasimba uye kunogumbura kamwe kamwe, asi zviri nyore kukurira mumazuva mashoma.
Kunyangwe Wallpaper ine hushamwari kwezvakatipoteredza inonyanya kuyerwa zvichienderana neVOC emissions
Parizvino, vanhu vazhinji vane nzwisiso isina kujeka yepfungwa yekuchengetedzwa kwezvakatipoteredza. Zvisinei, zvakakosha zvikuru kujekesa nyaya iyi nokuti chete nekuijekesa chete kunogona kuitwa zvose pamusoro penyaya iyi zviri nani.
Chekutanga, ingave iyo pachayo yakashandisa yakawandisa zviwanikwa; Chechipiri, zvinhu zvacho zvingangoora here (zvinowanzozivikanwa sekuora) mushure mekuraswa; Zvekare, ingave iyo zvinhu zvinoburitsa yakawandisa uye inoenderera VOC panguva yekushandiswa, uye kana zvinhu zvine muchetura zvinoburitswa panguva yekuora.
Kuti uwedzere kunanga, poindi yekutanga haitsanangurwe pano nekuti chokwadi, munhu wese haana hanya nenyaya iyi. Zvino, chinoda kusimbiswa ipfungwa yechipiri. Enzanisa isiri-yakarukwa uye PVC. PVC chigadzirwa chemakemikari, synthetic resin, polymer, uye chinobva kune petrochemical indasitiri. PVC ine purasitiki yakasimba uye inoshandiswa zvakanyanya. Mbatya dzinopfekwa nevanhu uye mbiya dzakashongedzerwa uye zvimiti zve microwave kumba zvese zvine kana zvine PVC zvinhu. Ichi chinhu chakaoma kudzikisira muzvisikwa, uye zvinogona kutora mazana kana kunyange zviuru zvemakore kutyora macheni epolymer uye kupedzisa maitiro ekudzikisira. Saka haisi chinhu chinochengetedza zvakatipoteredza.
Non woven paper (inowanzo zivikanwa sekuti non-woven fabric) imhando yekurukwa isina gwara, kureva, non-woven weaving. Chimiro chayo hachina kusununguka uye chinogona kuparara nyore nyore muzvisikwa. Saka, kana ichienzaniswa nePVC, ine zvishomazvinhu zvinochengetedza zvakatipoteredza.
Kuenzanisa kwehushamwari hwezvakatipoteredza kwezvinhu zviviri izvi kunobva pachiyero chekusvibiswa kwavanokonzera kune zvakatipoteredza mushure mekuraswa kana huwandu hwesimba (kana zvisikwa) zvinoshandiswa kuderedza zvinhu izvi.
Uyezve, kana zvasvika pakuchena kwechinhu chacho pachacho, PVC ndeyechikamu chepamusoro molecular weight polymers uye iri nyore; Kusiyana neizvi, zvigadzirwa zvemachira asina kurukwa zvine hunyoro. Machira asina kurukwa inzira yokuruka nayo, kwete machira acho. Inogona kuva zvinhu zvakasiyana-siyana zvisiri zvakarukwa.
Pfungwa yechitatu ndeyekuburitswa kweVOC. VOC=volatile organic compounds=formaldehyde, ether, ethanol, etc. Sezvo tichinyanya kunetseka nezve formaldehyde, inongonzi formaldehyde emissions.
Chinhu ichi chiri mu Wallpaper here? Zvinoenderana nemamiriro chaiwo. Ichokwadi here kuti zvese zvisiri-zvakarukwa zvinhu hazvina VOC, nepo PVC zvinhu zvichiita? Kwete, hazvisi.
Kune rudzi rweinki inonzi water-based ink, inoshandisa additives yakadai semvura uye ethanol panguva yekugadzira mavara, iyo inonyatsoenderana nemhoteredzo; Kune zvakare mhando yeinki inonzi solvent based ink (inowanzozivikanwa seoiri-based inki), iyo inoshandisa organic solvents sezvinowedzera mukuita kwemavara. Iyo inoputika organic komboni ine formaldehyde uye haina hushamwari kwezvakatipoteredza.
Zvemidziyo yePVC, nekuda kwechimiro chayo chakakora, mapfupi mabhesi makomisheni akadai se formaldehyde haakwanise kupinda. Naizvozvo, formaldehyde uye mamwe makomisheni anonamira pamusoro pePVC zvinhu uye zviri nyore kubuda. Mushure memazuva mashoma, ivo vanozoputika.
Iyi volatilization process inodaidzwa kuti VOC emissions.
Kune zvisiri-zvakarukwa, nekuda kwechimiro chazvo chakasununguka, organic solvents inogona kupinda mukati mechinhu, uye iyo volatilization process yemakomponi akadai se formaldehyde inononoka. Kune vagadziri vazhinji, kunyanya mabhurendi makuru, rudzi urwu rwe solvent based inki haruwanzo shandiswa. Kunyangwe ikashandiswa, mamwe malink anozowedzerwa mukuita kwekugadzira kupedzisa kuburitswa kweVOC.
Muchokwadi, mukushongedza kwemba, chinhu chinonyanya kutyiwa hachisi Wallpaper, asi mapaneru anoumbwa (kwete huni hwakasimba). Nekuti iyo VOC inoburitsa kubva kune akaumbwa mapaneru inononoka, ichitora yakati wandei mwedzi kana makore.
Anenge ese echokwadi mapikicha anopenya haasi machira asina kurukwa
Mamiriro ezvinhu aripo ndeokuti vatengesi vakawanda uye varidzi vezvitoro zvakakosha vachataura kuti micheka isiri-yakarukwa ndiyo inonyanya kushamwaridzana. Ndinoona izvi zvinoshamisa. Nei tichifanira kutaura izvi? Hamunzwisisi here? Kana kuti unotya kuti vatengi vanogona kurasikirwa nebhizinesi nekuisirwa pfungwa dzakadaro nezvimwe zvitoro zvewallpaper?
Kana Hapana chimwe chazvo! Chinokosha ndechekuti zvigadzirwa zveasina-yakarukwa Wallpaper hazvidhure, maitiro acho ari nyore, uye kushambadzira kunogona kutengeswa nemutengo wakakwira. Mhindu huru iri pano.
Ini handina kujairana nedzimwe nyika, asi zvirinani hapana chiitiko chakadaro muEurope. Muchokwadi, anenge ese makuru makuru epasi rose, angave ari Marburg, Aishi, Zhanbai Mansion, kana mapikicha akatanhamara, akagadzirwa nejira rePVC. Pakati pavo, iyo Wallpaper yeItari yekuratidzira horo ndeye PVC yakadzika yakashongedzwa.
Iye zvino zvinoratidzika kuti zvichida nyika yedu chete inofarira zvikuru pamusoro pepasi-yakarukwa wallpaper munyika, nokuti mumakore mashomanana apfuura, masupamaketi akashandisa zvishoma nezvishoma mabhegi asina kurukwa panzvimbo yemabhegi epurasitiki, uye mabhegi asina kurukwa ane mabhegi ane ushamwari. Inference: Asina kurukwa ane hushamwari kwezvakatipoteredza. Kudzivirirwa kwezvakatipoteredza kunodiwa zvechokwadi, asi kuburitsa kwe formaldehyde hakusi kunetseka.
Vagadziri vepamba vanofarira kugadzira nekutengesa machira asina-kurukwa, asi pane nyaya nedanho rehunyanzvi uye purofiti inofambiswa nezvinhu.
Machira asina kurukwa anokodzera nhanho iripo yehunyanzvi hwevagadziri vepamba (hapana embossing roller inodiwa, printing roller inoshandiswa. PVC surface inoda embossing roller yezvese yakadzika uye isina kudzika embossing, uye mutengo weembossing roller wakakwira. Mutengo wekugadzira welaser engraving embossing roller unotanga pa yuanraving muItaly inodhura 2000. Germany, iro rakavezwa rakavezwa embossing roller rinowanzoita mazana ezviuru zveeuro, iro rakanaka kwazvo uye ibasa rehunyanzvi.). Nekuda kweizvi, yemhando yepamusoro yePVC yekumusoro yemadziro inoda yakakosha mari yekumberi.
Kana kucherechedzwa kwemusika kusina kukwirira, mari ye embossing rollers ichaparara, izvo zvinounza njodzi huru. Iyo inodhinda roller inoshandiswa kune asina-kurukwa machira chete inodhura kupfuura chiuru cheyuan, ine mari shoma uye nekukurumidza mhedzisiro. Haisi tsitsi kuirasa watadza. Saka vagadziri vepamba vanoda kwazvo kugadzira isina-yakarukwa Wallpaper. Zvinoita sezvinonyatsoita mutemo we "pfupi, flat, uye nekukurumidza" kushanda kwefekitori.
Saizvozvo,zvisiri zvakarukwa zvinhuvane zvikanganiso zvakakura zviviri: chekutanga, pane nguva dzose kuine fuzziness mukuvara, nekuti pamusoro pezvinhu zvisiri-yakarukwa hazvina kukora zvakakwana, uye ruvara runoda kupinda. Chechipiri, kana inki-yakagadzirwa neoiri ikashandiswa, izvo zvinowedzera zveinki-yakagadzirwa nemafuta zvinopinda mukati meiyo isiri-yakarukwa machira, zvichiita kuti zviome kuburitsa formaldehyde.
