Uyilo, ukusebenza kakuhle kunye nokuqina kweeyunithi zokulawula ubushushu (TCUs) ziye zaphucula ulawulo lwenkqubo kulo lonke ishishini leplastiki ukusukela oko zaqala ukusetyenziswa ngoo-1960.Ngenxa yokuba ii-TCU zihlala zithembekile kwaye zisebenza ngeendlela ezahlukeneyo, zihlala zijikeleza kakhulu kwaye ziqhagamshelwe kwimithombo eyahlukeneyo yamanzi kunye neentlobo ezahlukeneyo zokubumba kunye nezixhobo zokusebenza.Ngenxa yobu bukho bexeshana, inkxalabo yokuqala yokusombulula ingxaki yee-TCUs ibandakanya ukuvuza.
Ukuvuza ngokuqhelekileyo kwenzeka ngenxa yesinye sezi meko zilandelayo - izixhobo ezikhululekile;iimpompo ezigugileyo okanye ukungaphumeleli kwesitywina;kunye neengxaki zomgangatho wamanzi.
Omnye weyona mithombo icacileyo yokuvuza ziifatisi ezikhululekileyo.Oku kunokwenzeka xa izinto ezininzi, ithumbu okanye izifakelo zemibhobho zidityanisiwe kwaye ziqhagamshelwe kwi-TCU.Ukuvuza kungaphuhliswa ekuhambeni kwexesha njengoko i-TCU ifumana imijikelo yokufudumeza kunye nokupholisa.Ukwenza uqhagamshelo oluvuzayo, kuhlala kungcono uku:
• Jonga umsonto wenkunzi nemazi ukuba kukho nakuphi na ukosuleleka okanye umonakalo.
Faka isitywini kumsonto oyindoda, usebenzisa izisongelo ezithathu zeteyiphu yeTeflon (PTFE), uze emva koko ufake isitywini solwelo somtywini oqala kumsonto wesibini, ngoko ke umsonto wokuqala otepiweyo udibana ngokucocekileyo.(Qaphela: kwimisonto ye-PVC, sebenzisa kuphela isitywina solwelo, ekubeni isambuku esongezelelweyo se-PTFE tape okanye uncamathisele izitywini zinokwenza kwaye zibangele ukuqhekeka.)
• Krwela umsonto wendoda kumsonto wemazi de uqine ngesandla.Phawula umgca ukunqumla kuyo yomibini imiphezulu yendoda/yebhinqa yoqhagamshelo ukubonisa indawo yokuhlala yokuqala.
Qinisa uqhagamshelo usebenzisa isikrufu esihlengahlengiswayo (kungekhona isixhasi sombhobho), usebenzisa nokuba yi-TFFT (uqinise umnwe kunye no-1.5 ukujika) okanye isikrufu setorque, kwaye uphawule indawo yokugqibela yokuqinisa kumphezulu omeleneyo.
