Isingeniso:
Amapulasitiki asetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yokuguquguquka kwawo kanye nokusebenza kahle kwezindleko.Kodwa-ke, ukuvutha kwawo kudala izingozi ezingaba khona, okwenza ukuncipha komlilo kube indawo ebalulekile yocwaningo.Lolu cwaningo lokuhlola luhlose ukuphenya ukusebenza kahle kwezinqamuleli zomlilo ezihlukene ekuthuthukiseni ukumelana nomlilo kwamapulasitiki.
Indlela yokwenza:
Kulolu cwaningo, sikhethe izinhlobo ezintathu zamapulasitiki ezivame ukusetshenziswa: i-polyethylene (PE), i-polypropylene (PP), ne-polyvinyl chloride (PVC).Uhlobo ngalunye lwepulasitiki lwalashwa ngezinqamuleli zamalangabi ezintathu ezihlukene, futhi izakhiwo zazo ezikwazi ukumelana nomlilo zaqhathaniswa namasampula angalashiwe.Izinqamuli zomlilo ezifakiwe bekuyi-ammonium polyphosphate (APP), i-aluminium hydroxide (ATH), ne-melamine cyanrate (MC).
Inqubo Yokuhlola:
1. Ukulungiselela Isampula: Izifanekiso zohlobo ngalunye lwepulasitiki zalungiswa ngokwezilinganiso ezijwayelekile.
2. Ukwelapha Okubushela Umlilo: Izinqamuleli zomlilo ezikhethiwe (i-APP, i-ATH, ne-MC) zixutshwe nohlobo ngalunye lwepulasitiki ngokulandela izilinganiso ezinconyiwe.
3. Ukuhlolwa Komlilo: Amasampula epulasitiki alashiwe nanganakiwe abekwe ngaphansi kokushisa kwelangabi okulawulwayo kusetshenziswa isishisi se-Bunsen.Isikhathi sokushisa, ukusabalala kwelangabi, kanye nokukhiqizwa kwentuthu kwabonwa futhi kwaqoshwa.
4. Ukuqoqwa Kwedatha: Izilinganiso zazihlanganisa isikhathi sokuthungela, izinga lokusabalala kwelangabi, nokuhlolwa okubonakalayo kokukhiqizwa kwentuthu.
Imiphumela:
Imiphumela yokuqala ibonisa ukuthi zonke izinqamuleli zomlilo ezintathu zathuthukisa ngempumelelo ukumelana nomlilo kwamapulasitiki.Amasampula alashiwe abonise izikhathi zokuthungela ezinde kakhulu kanye nokusabalala kwelangabi okuhamba kancane uma kuqhathaniswa namasampuli angakahlanzwa.Phakathi kwama-retardants, i-APP ibonise ukusebenza okungcono kakhulu kwe-PE ne-PVC, kuyilapho i-ATH ibonise imiphumela emangalisayo ye-PP.Ukukhiqizwa kwentuthu okuncane kwabonwa kumasampula alashiwe kuwo wonke amapulasitiki.
Ingxoxo:
Ukuthuthukiswa okuphawulwe ekumelaneni nomlilo kuphakamisa amandla alezi zinto ezivimbela amalangabi ukuthuthukisa ukuphepha kwezinto zepulasitiki.Umehluko ekusebenzeni phakathi kwezinhlobo zepulasitiki kanye nezinciphisi zamalangabi zingabangwa ukuhlukahluka kokwakheka kwamakhemikhali nokwakheka kwezinto.Ukuhlaziywa okwengeziwe kuyadingeka ukuze kuqondwe izindlela eziyisisekelo ezinesibopho semiphumela ebhekiwe.
Isiphetho:
Lolu cwaningo lokuhlola lugcizelela ukubaluleka kokubambezeleka kwelangabi kumapulasitiki futhi lugqamisa imiphumela emihle ye-ammonium polyphosphate, i-aluminium hydroxide, ne-melamine cyanrate njengezinqamuli zomlilo ezisebenzayo.Okutholakele kunomthelela ekuthuthukisweni kwezinto eziphephile zepulasitiki zokusetshenziswa okuhlukahlukene, kusukela ekwakhiweni kuya kwezimpahla ezithengwayo.
Ucwaningo Olwengeziwe:
Ucwaningo lwesikhathi esizayo lungangena ekusetshenzisweni kahle kwezilinganiso zokubuyiswa komlilo, ukuzinza kwesikhathi eside kwamapulasitiki alashiwe, kanye nomthelela wemvelo walezi zinto ezibuyisela amalangabi.
Ngokwenza lolu cwaningo, sihlose ukuhlinzeka ngemininingwane ebalulekile ekuthuthukisweni kwamapulasitiki angalangabi, ukukhuthaza izinto eziphephile kanye nokunciphisa izingozi ezihlobene nokuvutha kwepulasitiki.
