Izinto ezijwayelekile zokupakisha zidlala indima ebalulekile embonini yezimonyo njengoba zingagcini nje ngokuvikela imikhiqizo kodwa futhi zisiza ekuthuthukiseni ukubukeka kwazo. Phakathi kwabo, i-AS (i-acrylonitrile styrene) ne-PET (i-polyethylene terephthalate) isetshenziswa kabanzi ngenxa yezakhiwo zabo eziyingqayizivele. I-AS yaziwa ngokungafihli lutho nokukhanya kwayo okudlula ingilazi ejwayelekile. Lesi sici sivumela ukubuka okucacile kwesakhiwo sangaphakathi sephakheji, sithuthukisa ikhwalithi yokubuka iyonke.
I-AS inokumelana nokushisa okuhle kakhulu, amandla okuthwala umthwalo, nokumelana nokuguquguquka nokuqhekeka.
I-PET, ngakolunye uhlangothi, yaziwa ngokuthambile kwayo, ukukhanya okuphakeme (kufika ku-95%), nokuqina komoya okuphawulekayo, amandla acindezelayo, nokumelana namanzi. Kodwa-ke, ayikwazi ukumelana nokushisa futhi ivame ukusetshenziswa njengempahla yokupakisha yokudla, iziphuzo kanye nezimonyo.
Ekupakishweni kwezimonyo, ukukhetha kwempahla kubalulekile ukuze kuqinisekiswe ukuphepha nokukhanga komkhiqizo. I-AS iyinketho ethandwayo yokupakishwa kwezimonyo ngenxa yokucaca kwayo okuphakeme nokukhanya.
Inikeza umbono ocacile wesakhiwo sangaphakathi somkhiqizo, ithuthukisa ukukhanga okubonakalayo futhi ivumele amakhasimende ukuthi abone umkhiqizo ngaphambi kokuthenga.
Ukumelana nokushisa kwe-AS kanye nokumelana nomthelela omkhulu kuyenza ifanelekele ukuvikela izimonyo ezintweni zangaphandle, iqinisekisa ikhwalithi nobuqotho bazo.
Ngakolunye uhlangothi, i-PET isetshenziswa kakhulu ekufakweni kwezimonyo ngenxa yokungafihli kwayo okuphezulu nokuqina komoya okuhle kakhulu. Ukuthamba kwe-PET kuyivumela ukuthi yakhelwe ngendlela evumelana nezimoizinhlobonhlobo zokupakishwa kwezimonyo zomumo nosayizi.
Ukumelana kwayo okuphezulu kwamanzi kuqinisekisa ukuthi umkhiqizo uvikelekile emiphumeleni yomswakama, ugcina ikhwalithi yayo ngokuhamba kwesikhathi. Kodwa-ke, kufanele kuqashelwe ukuthi i-PET ayikwazi ukumelana nokushisa, ngakho-ke ivame ukusetshenziswa ekufakweni kwezimonyo okungadingi ukuvezwa emazingeni okushisa aphezulu.

Embonini yezimonyo eqhudelana kakhulu, ukupakishwa kudlala indima ebalulekile ekuheheni abathengi kanye nokuba nomthelela ezinqumweni zabo zokuthenga. Ukusetshenziswa kwe-AS ne-PET ekufakweni kwezimonyo kuhlangabezana nezidingo zokukhanga okubonakalayo nokuvikelwa komkhiqizo.
Ukucaca nokukhanya okuphakeme kwe-AS kuyenza ifanelekele ukubonisa imikhiqizo, kuyilapho i-PET imelana kakhulu namanzi kanye nokuqina komoya kuqinisekisa ukulondolozwa kwekhwalithi yomkhiqizo.
Izici ze-AS ne-PET zibenza bafanelekele izinhlobo ezahlukene zokupakishwa kwezimonyo.
Ngenxa yokucaca kwayo okuphezulu nokukhanya, i-AS ivamise ukusetshenziswa ezitsheni zezimonyo ezibonisa ngale, okuvumela amakhasimende ukuthi abone imikhiqizo engaphakathi. Ukumelana nokushisa kwayo okuhle kakhulu kanye nokumelana nomthelela kuyenza ifaneleke ukuvikela izimonyo ezihlukahlukene, ukuqinisekisa ukuphepha kwazo ngesikhathi sokuthutha nokugcinwa.
Ngakolunye uhlangothi, ukubonakala okuphezulu kwe-PET kanye nokuqina komoya kuyenza ifanele ukupakishwa okuhlukahlukene kwezimonyo, okuhlanganisa amabhodlela nezimbiza. Ukuthamba kwayo kuvumela ukuguquguquka komklamo, okuvumela ukudalwa kwamaphakheji ayingqayizivele futhi akhangayo ezimonyo.
Ngaphezu kokukhanga kwayo okubonakalayo, ukumelana kwamakhemikhali kwe-AS kanye nokumelana namanzi kwe-PET kuyenza ifaneleke ukugcina izimonyo ezihlukahlukene.
Ukumelana namakhemikhali e-AS kuqinisekisa ukuthi ukupakishwa kuhlala kuqinile lapho kuthintana namafomula ezimonyo, kuyilapho ukumelana kwamanzi okuphezulu kwe-PET kuvikela umkhiqizo emswakama, ngaleyo ndlela kugcinwe ikhwalithi yayo ngokuhamba kwesikhathi.
Lezi zakhiwo zenza i-AS ne-PET aukukhetha okuthembekile kokupakishwa kwezimonyo, ukuhlangabezana nezidingo zemboni zokusebenza nezobuhle.
Ukusetshenziswa kwe-AS ne-PET ekufakweni kwezimonyo kukhombisa ukuzibophezela kwemboni ekuhlinzekeni abathengi ngemikhiqizo yekhwalithi ephezulu nebukekayo. Izakhiwo eziphakeme zalezi zinto zisiza ukuthuthukisa konke okuhlangenwe nakho kokusebenzisa izimonyo, kusukela ngesikhathi sokuthenga kuya ekusetshenzisweni komkhiqizo. Ukuba sobala nokukhanya kwe-AS kwenza amakhasimende akwazi ukwenza izinqumo ezinolwazi, kuyilapho i-PET ingakwazi ukumelana namanzi kanye nokuqina komoya kuqinisekisa ikhwalithi yomkhiqizo.
Ukusetshenziswa kwe-AS ne-PET ezintweni zokupakisha zezimonyo kukhombisa ukuzibophezela kwemboni ekuhlinzekeni abathengi ngemikhiqizo ephephile, emihle nesezingeni eliphezulu.
Izici eziyingqayizivele ze-AS ne-PET zizenza zifanelekele inhlobonhlobo yokupakishwa kwezimonyo, zihlangabezana nezidingo zemboni zokusebenza nobuhle. Njengoba imboni yezimonyo iqhubeka nokuvela, ukusetshenziswa kwezinto ezintsha zokupakisha ezifana ne-AS ne-PET kuzodlala indima ebalulekile ekuhlangabezaneni nesidingo sabathengi sezimonyo ezikhangayo nezithembekile.
