Qalabka baakadaha cuntada caafimaad ma laha halbeeg midaysan wakhtigan la joogo gudaha ma qaabeeyo midaysan, waxqabadka caadiga ah ee alaabta baakadaha cuntada, iyo kaliya in tiro yar oo ah alaabta ee xeerarka caadiga ah, sida baakadaha dabacsan GB/T10004 & ndash;
2008 baakadaha filimka isku dhafan caag ah, bac, xarunta qalalan extrusion ka kooban, 'tusayaal haraaga dareeraha ee qodobada u dhigma.

Inta badan heerarka nadaafadda ee alaabta baakadaha cuntada laguma dabaqi karo hadda iyo in ka badan noocyada baakooyinka cuntada.
Helitaanka haraaga dareeraha ah, dalal kala duwan oo ku wajahan bartilmaameedyada alaabteeda.
In GB / T10004 & ndash;
2008 baakadaha filimka isku dhafan caag ah, bac, xarunta extrusion qalalan, 'Qodobka ugu muhiimsan ee qadarka haraaga dareeraha caadiga ah kama badna 5 mg / m2, laakiin ma cayimin nooca dareeraha, inta u dhaxaysa 5 mg / m2 dhammaan noocyada kala duwan ee tirada dareere sidoo kale ma sameeyaan qaybin faahfaahsan.
Heerka caafimaadka qaranka waxa kale oo uu mamnuucayaa isticmaalka caagagga wasakhda ah sida wax soo saarka alaabta ceeriin ee weel cunto caag ah.
Laakiin waxa kale oo jira qarin weyn oo waxyeello ah, oo laga sameeyay alaabta ceeriin ee weelasha cuntada caagga ah.
Xaddiga caadiga ah ee weelka caagga ah ee xaddidan oo aad u dabacsan, guddiga heer qaran ayaa hadda ka shaqaynaya sidii loo cusboonaysiin lahaa oo loo horumarin lahaa shaqada caadiga ah.

Inta badan qalabka baakadaha halbeegyada wax soo saarka ma aha oo kaliya qaybta looga baahan yahay ogaanshaha haraaga dareeraha sharaxaadda caadiga ah ee qaar ka mid ah tusmooyinka dareenka fudud, sida alaabta wax lagu duubo waa in aanay yeelan ur gaar ah, xirxirida dareeraha qooyay ma yeelan karaan ur gaar ah, iwm. , laakiin waxaa jira Ma jiraan tilmaameyaal gaar ah oo la soo bandhigay.
Baakadaha cuntada ee habka wax soo saarka iyo lama huraanka ayaa jira dareerayaal hadhaaga ah.
In gravure daabacaadda walxaha isku dhafan caag ah iyo nidaamka qalalan dareere qalalan, waxay u baahan yihiin in la isticmaalo wax badan oo dareere organic sida toluene, ethyl acetate iyo ethyl ketone, iwm. uumi baxa, laakiin sababo kala duwan ee wax soo saarka dhabta ah waxaa had iyo jeer noqon doona wax ka badan ama ka yar ma aha dareere aan gebi ahaanba kacsan, oo loo yaqaan dareerayaasha haraaga ah.
Walxaha haraaga ah waa isku darka noocyo kala duwan oo dareere ah, badiyaa marka nuxurka dareerayaasha haraaga ah ee ka hooseeya heer cayiman ay qiimeeyaan dareenka urta dadku ma dareemi karaan jiritaankiisa, laakiin haraaga dareeraha dareeraha ah ee dadku waxay dareemi karaan.

Duubka caaga ah ee kansarka ayaa sababay saameyn xooggan gudaha guriga.

Baakadaha cuntada ee 1988 PVC qaabaynta heerka caafimaadka badeecada 'si gaar ah, waxa ku jira vinyl chloride monomer waa wax ka yar ama la mid ah 1 mg halkii kiilo.
Halabuurka vinyl chloride monomer wuxuu ku jiraa filimka cunnada ee PVC, ka dib markii ay ka qayb qaadanayso jidhka bini'aadamka ayaa leh kansar.
Midowga Yurub iyo Maraykanka, Japan, ayaa mamnuucay badeecadan loo isticmaalo cuntada.
La cusboonaysiiyay dhawr jeer, laakiin inta badan si loo beddelo qaar ka mid ah cabbirradan.

Dhacdooyinka filimka Cling & oo dhan;
Mar kale ayaa daaha ka fayday halbeegyada dalkeenu ku habboon yahay ee soo saaray habacsanaanta shaqada.
Markaa baakadaha cuntada si loo ogaado hadhaaga dareeraha ah si loo horumariyo tusmaynta tirada waa lama huraan.
