Umphumela wezimonyo awuxhomekile kuphela kufomula yayo yangaphakathi, kodwa futhiezintweni zayo zokupakisha. Ukupakishwa okufanele kungaqinisekisa ukuzinza komkhiqizo nolwazi lomsebenzisi. Nazi izici ezimbalwa ezibalulekile okufanele uzicabangele lapho ukhethaukupakisha izimonyo.
Okokuqala, sidinga ukucabangela inani le-pH nokuzinza kwamakhemikhali omkhiqizo. Isibonelo, ama-depilatory creams namadayi ezinwele ngokuvamile anenani eliphezulu le-pH. Emikhiqizweni enjalo, izinto ezihlanganisiwe ezihlanganisa ukumelana nokugqwala kwamapulasitiki nokungafinyeleli kwe-aluminium yizinketho ezifanelekile zokupakisha. Ngokuvamile, isakhiwo sokupakisha semikhiqizo enjalo sizosebenzisa izinto eziyinhlanganisela yezendlalelo eziningi ezifana ne-polyethylene/aluminium foil/polyethylene noma i-polyethylene/paper/polyethylene.
Okulandelayo ukucatshangelwa kokuqina kombala. Eminye imikhiqizo efiphala kalula, njengezimonyo ezine-pigment, ingase intanteamabhodlela engilazi. Ngakho-ke, kule mikhiqizo, ukukhetha izinto zokupakisha ezi-opaque, njengamabhodlela epulasitiki angenalutho noma amabhodlela engilazi aboshwe, kungavimbela ngokuphumelelayo izinkinga ezibunayo ezibangelwa imisebe ye-ultraviolet.
Izimonyo ezinengxube yamanzi kawoyela, njengamafutha okhilimu emanzini, zihambisana kakhulu namapulasitiki futhi zifanele ukupakishwa ezitsheni zepulasitiki. Ngemikhiqizo yomoya efana nezibulala-zinambuzane, ukupakishwa kwe-aerosol kuyisinqumo esihle ngenxa yomphumela wayo omuhle wokusebenzisa.
Ukuhlanzeka nakho kubalulekile ekukhetheni amaphakheji. Isibonelo, imikhiqizo yokupakisha yasesibhedlela ifaneleka kakhulu ukupakishwa kwepompo ukuze kugcinwe umkhiqizo uhlanzekile.
Ngokwezinto zokwakha, i-PET (i-polyethylene terephthalate) ifanele ukupakisha amakhemikhali nsuku zonke ngenxa yezakhiwo zayo zamakhemikhali ezinhle nokungafihli. I-PVC (i-polyvinyl chloride) idinga ukunaka inkinga yokuwohloka ngesikhathi sokushisa, futhi ngokuvamile idinga ukungeza ama-stabilizers ukuthuthukisa izakhiwo zayo. Iziqukathi zensimbi zisetshenziswa kakhulu ekufakweni kwemikhiqizo ye-aerosol, kuyilapho iziqukathi ze-aluminium zisetshenziselwa ukwenza iziqukathi ze-aerosol, izindebe zomlomo nokunye ukupakishwa kwezimonyo ngenxa yokucubungula kwazo kalula kanye nokumelana nokugqwala.
Njengenye yezinto ezindala kakhulu zokupakisha, ingilazi inezinzuzo zokungangeni kwamakhemikhali, ukumelana nokugqwala, nokungavuzi, futhi ifaneleka ngokukhethekile emikhiqizweni yokupakisha engenazo izithako ze-alkaline. Kodwa okubi kwayo ukuthi i-brittle futhi ithambile.
Ukupakishwa kwepulasitiki kusetshenziswa kabanzi ngenxa yokuklama kwayo okuguquguqukayo, ukumelana nokugqwala, izindleko eziphansi, nokunganqamuki, kodwa kuyadingeka ukuqaphela ukuthi ukuvuthwa kwama-propellants nezinto ezisebenzayo kumapulasitiki athile kungase kuthinte ikhwalithi yomkhiqizo.
Okokugcina, kufanele sicabangele ukupakishwa kwemikhiqizo ye-aerosol. Imikhiqizo enjalo ivamise ukusebenzisa iziqukathi ezimelana nokucindezela njengensimbi, ingilazi noma ipulasitiki. Phakathi kwazo, amathini e-aerosol anezicucu ezintathu yi-tinplate asetshenziswa kakhulu. Ukuze uthuthukise umphumela we-atomization, idivayisi enembobo yesigaba segesi ingasetshenziswa futhi.
Ukukhethwa kweukupakisha izimonyokuyinqubo eyinkimbinkimbi yokwenza izinqumo, edinga ukuthi abakhiqizi baqinisekise ikhwalithi yomkhiqizo kuyilapho becabangela nokuvikelwa kwemvelo, izindleko, kanye nokusebenziseka kalula. Ngokuhlaziya kwesayensi nokuklama ngokucophelela, ukupakishwa kwezimonyo kungadlala indima ebalulekile ekuvikeleni imikhiqizo nasekuthuthukiseni ulwazi lwabathengi.
