1. Ho ntse ho e-na le lekhalo le itseng pakeng tsa lithuso tsa ho sebetsa tsa PVC tsa malapeng le lihlahisoa tsa linaheng tse ling, 'me theko e tlaase ha e na molemo o moholo tlhōlisanong ea' maraka.
Leha lihlahisoa tsa lehae li na le melemo e itseng ea sebaka le litheko tlholisanong ea 'maraka, re na le likheo tse itseng ts'ebetsong ea lihlahisoa, mefuta-futa, botsitso, le likarolo tse ling ha li bapisoa le lihlahisoa tsa kantle. Sena se amana le ho salla morao ha foromo ea sehlahisoa sa rona, theknoloji ea ho sebetsa, ho sebetsa le theknoloji ea kamora kalafo. Likhoebo tse ling tsa malapeng li tseba litaba tsena ka botlalo 'me li thehile likamano tsa tšebelisano le litsi tsa lipatlisiso, litsi tsa lipatlisiso le nts'etsopele,' me li entse lipatlisiso ka li-additives tsa polasetiki.
2. Lifeme tse nyane li fapane mme ha ho na khoebo e etelletseng pele e nang le maemo a felletseng, e lebisang tlholisanong e sa laoleheng 'marakeng.
Hona joale, ho na le baetsi ba ACR ba ka bang 30 ba malapeng, empa ke ba 4 feela ba bona ba nang le tlhahiso e kholo (ka matla a selemo le selemo a ho kenya lithane tse fetang 5000). Lihlahisoa tsa likhoebo tsena tse kholo li thehile setšoantšo se setle limmarakeng tsa lehae le tsa machabeng, ho sa natsoe mefuta ea lihlahisoa le boleng. Empa lilemong tse peli tse fetileng, ka katleho ea indasteri ea ts'ebetso ea PVC, lifeme tse ling tse nyane tsa ACR tse nang le matla a ho hlahisa lithane tse ka tlase ho 1000 li potlakile ho ea 'marakeng. Ka lebaka la lisebelisoa tsa bona tse bonolo tsa tlhahiso le botsitso bo fokolang ba lihlahisoa, likhoebo tsena li ka phela feela ka ho sebelisa ho lahloa ha theko e tlase, ho bakang tlholisano e matla ea theko 'marakeng oa lehae. Lihlahisoa tse ling tsa boleng bo tlase le maemo a tlase li ile tsa tlala 'maraka hang-hang, tsa tlisa litlamorao tse mpe ho likhoebo tse sebetsanang le maemo a tlase mme tsa tlisa litlamorao tse mpe ho nts'etsopele ea indasteri. Ho khothalletsoa hore Mokhatlo oa Plastic Processing Association o etelle pele ho theha ACR Additive Industry Association, ho kopanya litekanyetso tsa indasteri, ho laola tsoelo-pele ea indasteri, ho felisa lihlahisoa tsa maiketsetso le tse tlaase, le ho fokotsa tlhōlisano e sa laoleheng. Ka nako e ts'oanang, likhoebo tse kholo li lokela ho eketsa boiteko ba tsona ba nts'etsopele ea lihlahisoa, ho lokisa sebopeho sa lihlahisoa tsa bona, le ho boloka tsoelo-pele e lumellanang le lihlahisoa tse tšoanang tsa kantle ho naha.
3. Ho phahama ha litheko tsa oli e tala ho entse hore ho be le keketseho ea litheko tsa thepa e tala le phokotseho ea phaello ea likhoebo.
Ka lebaka la ho phahama ho tsoelang pele ha litheko tsa oli e tala ea machaba, lisebelisoa tsohle tsa mantlha tsa tlhahiso ea ACR, methyl methacrylate le acrylic ester, li phahame haholo. Leha ho le joalo, bareki ba tlase ba saletse morao keketsehong ea litheko tsa sehlahisoa, e bakileng phokotso e akaretsang ea phaello bakeng sa likhoebo tse sebetsanang le ACR. Sena se lebisitse boemong ba tahlehelo bakeng sa indasteri eohle ka 2003 le 2004. Hona joale, ka lebaka la ho tsitsisa ha theko ea lihlahisoa tse tala, indasteri e bontšitse mokhoa o motle oa phaello.
4. Khaello ea litalenta tsa profeshenale, lipatlisiso tsa indasteri ha lia khona ho nts'etsapele ka botebo
Ka lebaka la hore motsoako oa ACR ke motsoako oa polymer o hlahisitsoeng feela Chaena ho elella bofelong ba lilemo tsa bo-1990, likarolo tsa eona tsa lipatlisiso le nts'etsopele le bafuputsi ba batla ba fokola ha ba bapisoa le lisebelisoa tse ling tse kang li-plasticizers le li-flame retardants Chaena. Esita le haeba ho na le mekhatlo ea lipatlisiso ka bomong e e ntlafatsang, ho haella ha kopano e ntle pakeng tsa bafuputsi le indasteri ea ho lokisa polasetiki ho entse hore ho se khonehe ho tebisa lipatlisiso tsa lihlahisoa. Hajoale, nts'etsopele ea ACR naheng ea China e its'etleha feela ho litsi tsa lipatlisiso tse nang le likhoebo tse 'maloa ho hlophisa le ho nts'etsapele. Leha ho entsoe likatleho tse itseng, ho na le lekhalo le leholo lipakeng tsa balekane ba lehae le ba kantle ho naha mabapi le lichelete tsa lipatlisiso, lisebelisoa tsa lipatlisiso le nts'etsopele, le boleng ba lipatlisiso le nts'etsopele. Haeba boemo bona bo sa ntlafatsoe hantle, ho tla be ho sa tsejoe hore na lithuso tsa ho sebetsa li ka ema li tiile 'marakeng oa lehae nakong e tlang.
