Ulwazi oluthile ngamapayipi ezimonyo epulasitiki
Ishubhu yezimonyo yepulasitikiAbakhiqizi abaningi bezimonyo bayathandwa ngenxa yesisindo sabo esilula, ukuphatheka kalula, ukuqina, ukuphindeka kalula, ukucindezelwa kalula, ukusebenza kahle kokucubungula kanye nokunyatheliswa kalula. Asetshenziswa kabanzi ekupakisheni cishubhu elithambile le-osmetic imikhiqizo efana nezihlanzi zobuso (izihlanzi zobuso, njll.), imikhiqizo yokunakekela isikhumba (okhilimu abahlukahlukene bamehlo, okhilimu abamanzi, okhilimu abanomsoco, okhilimu ababandayo kanye nemithi yokuvikela ilanga, njll.) kanye nemikhiqizo yokunakekela ubuhle nezinwele (ama-shampoo, ama-conditioner, izindebe zomlomo, njll.).
Kulabo abangajwayelene ipayipi lezimonyo lepulasitikis, ukuklama uhlaka ngokwalo kungaba umsebenzi okhathazayo. Uma kwenzeka iphutha, wonke umsebenzi ungonakala. Abahlinzeki bekhwalithi ephezulu bazoklama uhlaka olulula kulabo abangajwayelene nalo ipayipi lezimonyo lepulasitikis. Ngemva kokuba ububanzi nobude beshubhu sekunqunyiwe, bazokunikeza imephu yendawo yokuklama. Udinga nje ukubeka okuqukethwe komklamo ngaphakathi kwendawo yemephu bese uyibeka phakathi. Abahlinzeki bekhwalithi ephezulu bazohlola futhi banikeze iziphakamiso mayelana nomklamo wakho kanye nenqubo yokukhiqiza. Isibonelo, uma indawo yeso le-photoelectric ingalungile, bazokwazisa; uma umbala ungafaneleki, bazokhumbuza; uma imininingwane ingahambisani nomklamo, bazokhumbuza ngokuphindaphindiwe ukuthi ushintshe uhlaka; isibonelo, ukuthi ngabe isiqondiso kanye nokufunda kwebhakhodi kuyafaneleka yini, ukuthi ukuhlukaniswa kombala kanye nenqubo kungakhiqiza yini. ishubhu elithambile lobuhle, ngisho namaphutha amancane njengokuthi uhlaka alugobile, abahlinzeki bekhwalithi ephezulu bazokuhlola ngamunye ngamunye.
Izinto ezisetshenziswayo kumele zihlangabezane nezindinganiso zokuhlanzeka ezifanele, futhi okuqukethwe yizinsimbi ezisindayo, izinto ezikhanyisa ukukhanya nezinye izinto eziyingozi kufanele kulawulwe ngaphakathi kobubanzi obubekiwe. Isibonelo, nge ipayipi lezimonyo lepulasitikiUma ithunyelwa e-United States, i-polyethylene (PE) kanye ne-polypropylene (PP) ezisetshenziswayo kumele zihlangabezane nezindinganiso ze-US Food and Drug Administration (FDA).
Kunezindlela ezimbili zokugcwalisa ipayipi lezimonyo lepulasitikis: ukugcwalisa okuvela ku- ishubhu elithambile lobuhleumsila kanye nokugcwalisa okuvela emlonyeni wethubhu. Uma kugcwaliswe kusuka emlonyeni wethubhu, uma uthenga ipayipi lezimonyo lepulasitiki, kufanele uqaphele ukuthi "usayizi womlomo wethubhu kanye nosayizi womlomo wokugcwalisa" kuyahambisana yini nokuthi kungafakwa kalula yini ethubhu. Uma igcwele kusukela emsileni wethubhu, udinga ukuyifaka ebhokisini ipayipi lezimonyo lepulasitikifuthi ucabangele isiqondiso sekhanda nomsila womkhiqizo, nokuthi ungayenza kanjani inqubo yokugcwalisa ibe lula futhi isheshe. Okwesibili, udinga ukwazi ukuthi okuqukethwe okugcwalisiwe ngesikhathi senqubo yokugcwalisa "kuwukugcwalisa okushisayo" noma kusesilinganisweni sokushisa segumbi. Ngaphezu kwalokho, inqubo yalo mkhiqizo ivame ukuhlobana nomklamo. Udinga ukuqonda umongo wokukhiqiza ukugcwalisa kusenesikhathi ukuze ugweme izinkinga futhi ufinyelele ukusebenza kahle kokukhiqiza okuphezulu.
