Badbaadada baakadaha cuntada

Baakadaha cuntada ee nadaafadda heerka caadiga ah waa mid aan dhammaystirnayn

(1) Agabka baakadaha cuntada caafimaadka ma laha heer midaysan oo hadda gudaha ah, mana laha qaab-dhismeed midaysan oo heeraysan oo ah agabka baakadaha cuntada caafimaadka, waxaana lagu sameeyaa tiro yar oo badeecooyin ah oo ku jira xeerarka caadiga ah, sida baakad dabacsan oo ah filimka isku-dhafka balaastikada ah ee GB/T10004 & ndash; 2008 ee baakadaha, bacda, isku-dhafka qalalan ee isku-dhafka ah, 'tilmaamaha haraaga dareeraha ah ee qodobbada u dhigma.

(2) Inta badan heerarka nadaafadda ee agabka baakadaha cuntada laguma dabaqi karo hadda noocyo badan oo baakadaha cuntada ah. Si loo ogaado haraaga dareeraha ah, waddamo kala duwan ayaa bartilmaameedsanaya qodobbadiisa. Qodobka GB/T10004 & ndash; 2008 ee baakadaha filimka isku-dhafka ah ee balaastikada ah, bacda, isku-dhafka qalajinta ee isku-dhafka ah, 'qodobada ugu muhiimsan ee ku jira xaddiga haraaga dareeraha caadiga ah kama badna 5 mg/m2, laakiin ma aysan cayimin nooca dareeraha, oo u dhexeeya 5 mg/m2 dhammaan noocyada dareeraha ah sidoo kale ma sameeyaan qaybin faahfaahsan. Heerka caafimaadka qaranka ayaa sidoo kale mamnuucaya isticmaalka balaastikada qashinka ah sida wax soo saarka alaabta ceeriin ee weelasha cuntada balaastikada ah. Laakiin waxaa sidoo kale jira qarin weyn oo waxyeelada ah, oo laga sameeyay weelasha cuntada balaastikada ah ee warshadaha. Xadka tusmada heerka weelka balaastikada ah oo aad u dabacsan, guddiga heerka qaran ayaa hadda ka shaqeynaya sidii loo cusbooneysiin lahaa loona horumarin lahaa shaqada caadiga ah.

(3) Heerarka badeecadaha badankood ee qalabka baakadaha ma aha oo kaliya qaybta u baahan ogaanshaha haraaga dareeraha ah qeexitaanka heerka tilmaamaha dareenka fudud ee qaar ka mid ah tilmaamaha dareenka fudud, sida walxaha baakadaha waa inaysan lahayn ur gaar ah, baakadaha dareeraha qooya ma yeelan karaan ur gaar ah, iwm., laakiin ma jiraan shuruudo tilmaame tiro gaar ah oo la soo bandhigay. Baakadaha cuntada ee habka wax soo saarka iyo lama huraan waxaa jira dareere haraaga ah. Daabacaadda gravure, walxaha isku-dhafka ah ee balaastikada iyo habka isku-dhafka qalalan ee dareeraha, waxaa loo baahan yahay in la isticmaalo dareere badan oo dabiici ah sida toluene, ethyl acetate iyo ethyl ketone, iwm., iyadoo la raacayo shuruudaha habka dareeraha ee habka wax soo saarka waa in la uumi bixiyaa, laakiin sababo kala duwan awgeed, wax soo saarka dhabta ah had iyo jeer waxaa jiri doona dareere aan gebi ahaanba isbeddelin, oo loo yaqaan dareere haraaga ah. Dareeraha haraaga ah waa isku-darka noocyo badan oo dareere ah, badanaa marka waxa ku jira dareere haraaga ah ee ka hooseeya heerka cayiman dareenka urta dadku ma dareemi karo jiritaankiisa, laakiin haraaga dareeraha sare ee dadku dareemaan way arki karaan. Sida PVC (PVC) Duubka balaastikada ah ee kansarka ayaa sababay saameyn xooggan oo ka jirta guriga. 《GB9681— 1988 heerka caafimaadka ee badeecadaha wax lagu sameeyo PVC ee baakadaha cuntada 'sida ku xusan shuruud gaar ah, maaddada vinyl chloride monomer-ka waxay ka yar tahay ama la mid tahay 1 mg kiilo garaamkiiba. Halabuurka vinyl chloride monomer-ka ayaa ku jira filimka dhegaha PVC, ka dib markii uu gacan ka geysto jirka bini'aadamka inuu leeyahay kansar. Midowga Yurub iyo Mareykanka, Japan, ayaa mamnuucay badeecadan loo isticmaalo cuntada. Dhowr jeer ayaa la cusbooneysiiyay, laakiin inta badan si loo beddelo qaar ka mid ah xuduudahan. "Dhacdooyinka filimka dhegaha & guud ahaan; Mar labaad ayaa la soo bandhigay heerarka khuseeya ee dalkeenna oo soo saaray dib u dhaca shaqada. Markaa agabka baakadaha cuntada ee ogaanshaha haraaga dareeraha si loo sameeyo tusmada tirada waa lama huraan.
