Njengamanje, ukupakishwa kwesikhwama sokuma kusetshenziswe kabanzi ezingutsheni, eziphuzweni zejusi, eziphuzweni zezemidlalo, emanzini okuphuza asemabhodleleni, ijeli emuncayo, izinongo neminye imikhiqizo. Ukusetshenziswa kwemikhiqizo enjalo nakho kuyakhula kancane kancane. Isikhwama sokuma sibhekisela esikhwameni sokupakisha esiguquguqukayo esinesakhiwo sokusekela esivundlile phansi, esinganciki kunoma yikuphi ukwesekwa futhi esingama sodwa kungakhathaliseki ukuthi isikhwama sivuliwe noma cha. Isikhwama sokuma siyindlela entsha yokupakisha, enezinzuzo zokuthuthukisa ikhwalithi yomkhiqizo, ukuqinisa umphumela obonakalayo wamashalofu, ukuphatheka kalula, ukusetshenziswa kalula, ukugcinwa kanye nokuvalwa. Isikhwama sokuma senziwe ngesakhiwo se-PET/foil/PET/PE esibekwe nge-laminated, futhi singaba nezendlalelo ezimbili, izendlalelo ezintathu nezinye izinto zezinye izici. Kuncike emikhiqizweni ehlukene yephakheji. Isendlalelo sokuvikela isithiyo se-oxygen singangezwa njengoba kudingeka ukunciphisa ukungena kwe-oxygen. , kwandise impilo yeshelufu yomkhiqizo. Ngakho-ke yiziphi izinhlobo zezikhwama zokuma?
1. Isikhwama sokuma esivamile:
Uhlobo olujwayelekile lwesikhwama sokuma lusebenzisa isimo semiphetho emine yokuvala, engeke ivalwe futhi ivulwe ngokuphindaphindiwe. Lolu hlobo lwesikhwama sokuma luvame ukusetshenziswa embonini yezinto zezimboni.
2. Isikhwama sokuma esinomlomo wokumunca:
Isikhwama sokuma esinomlomo wokumunca kulula kakhulu ukuthulula noma ukumunca okuqukethwe, futhi singavalwa futhi sivulwe ngesikhathi esifanayo, okungabhekwa njengokuhlanganiswa kwesikhwama sokuma kanye nomlomo webhodlela ojwayelekile. Lolu hlobo lwesikhwama sokuma luvame ukusetshenziswa ekupakisheni izidingo zansuku zonke, zeziphuzo, ijeli yokugeza, ishampu, i-ketchup, uwoyela odliwayo, ijeli kanye neminye imikhiqizo ewuketshezi, i-colloid, ne-semi-solid, njll.
3. Isikhwama sokuma esineziphu:
Amaphakethe azisekelayo anama-zipper nawo angavalwa futhi avulwe kabusha. Njengoba ifomu le-zipper lingavaliwe futhi amandla okuvala elinganiselwe, leli fomu alifanele ukufaka uketshezi nezinto ezishintshashintshayo. Ngokwezindlela ezahlukene zokuvala umphetho, lihlukaniswe ukuvala umphetho onqenqemeni olune kanye nokuvala umphetho onqenqemeni olune. Ukuvala umphetho onqenqemeni olune kusho ukuthi ukupakishwa komkhiqizo kunesendlalelo sokuvala umphetho ojwayelekile ngaphezu kokuvala i-zipper lapho iphuma efektri. I-zipper isetshenziselwa ukufeza ukuvala nokuvula okuphindaphindiwe, okuxazulula inkinga yokuthi amandla okuvala umphetho onqenqemeni olune-zipper mancane futhi awalungele ukuthuthwa. Umphetho ovaliwe kathathu uvalwe ngqo ngomphetho onqenqemeni olune-zipper, ovame ukusetshenziselwa ukubamba imikhiqizo elula. Amaphakethe azisekelayo anama-zipper ngokuvamile asetshenziselwa ukupakisha ezinye izinto eziqinile ezilula, njengeswidi, amabhisikidi, ijeli, njll., kodwa amaphakethe azisekelayo anamacala amane angasetshenziswa futhi ukupakisha imikhiqizo esindayo njengelayisi kanye nodoti wekati.
4. Isikhwama sokuma esimile njengomlomo
Amaphakethe okuma ngomlomo okulingisayo ahlanganisa ukulula kwamaphakethe okuma nama-nozzle okumunca kanye nokushibhile kwamaphakethe okuma avamile. Okusho ukuthi, umsebenzi we-nozzle yokumunca ubonakala ngesimo somzimba wesikhwama ngokwaso. Kodwa-ke, isikhwama sokuma esinomumo womlomo asikwazi ukuvalwa kabusha. Ngakho-ke, ngokuvamile sisetshenziswa ekupakisheni imikhiqizo yoketshezi, i-colloidal kanye nemikhiqizo eqinile esetshenziswa kanye njengeziphuzo kanye nejeli.
5. Isikhwama sokuma esinomumo okhethekile:
Okusho ukuthi, ngokwezidingo zokupakisha, izikhwama ezintsha zokuma ezinezimo ezahlukahlukene ezikhiqizwa ngokushintsha ngokusekelwe ezinhlotsheni zezikhwama zendabuko, njengokuklama okhalweni, ukwakheka kokuguquguquka kwezansi, ukwakheka kwezibambo, njll. Ngokuthuthuka komphakathi, ukuthuthuka kwezinga lobuhle babantu kanye nokuqina kokuncintisana ezimbonini ezahlukahlukene, ukwakheka nokunyatheliswa kwezikhwama zokuma sekunemibala eminingi. Kunezinhlobo eziningi zokuveza, futhi ukuthuthukiswa kwezikhwama zokuma ezinezimo ezikhethekile kuthambekele ekuthatheni indawo kancane kancane yesimo sezikhwama zokuma zendabuko.
