Njengamanje, izikhwama zepulasitiki ezithengiswa emakethe ngokuyinhloko zihlukaniswe ngezigaba ezintathu ngokwezinto zokusetshenziswa: isigaba sokuqala yi-polyethylene, esetshenziselwa ikakhulukazi ukupakisha izithelo nemifino evamile;isigaba sesibili yi-polyvinylidene chloride, esetshenziselwa ikakhulukazi ukudla okuphekiwe., Ham kanye neminye imikhiqizo;isigaba sesithathu yizikhwama zepulasitiki ze-polyvinyl chloride.Izikhwama zepulasitiki ze-Polyvinyl chloride zidinga ukungezwa nezithasiselo ngesikhathi sokukhiqiza.Lezi zithasiselo ziphuma kalula uma zishisiwe noma zithintana nokudla okunamafutha, futhi zihlala ekudleni futhi zidale ukulimala emzimbeni womuntu.Ngakho-ke, ungafaki imifino nokunye ukudla esikhwameni sepulasitiki.Yishise ku-microwave, futhi ungafaki isikhwama sepulasitiki esiqandisini.
Ngaphezu kwalokho, isikhwama sepulasitiki esenziwe nganoma iyiphi into kufanele sisetshenziswe ngokuhambisana nebanga lokushisa elichazwe ekufakweni komkhiqizo, futhi isikhwama sepulasitiki akufanele sithintane ngqo nokudla isikhathi eside.Lapho ufudumeza, shiya isikhala noma ubhoboze izimbobo ezincane ezimbalwa esikhwameni sepulasitiki.Ukuze ugweme ukuqhuma, futhi uvimbele izinga lokushisa eliphezulu lomhwamuko ukuba ungangeni ekudleni ovela esikhwameni sepulasitiki.
Ubisi olusesikhwameni esiyisicaba kuphephile ukuthi lungaphuzwa: Isikhwama esiyisicaba esisetshenziselwa ukupakisha ubisi akusona ungqimba lwefilimu.Ukuze kugcinwe ukuqina komoya, izikhwama zepulasitiki ezijwayelekile zenziwe ngezingqimba eziningi zefilimu, kanti ungqimba lwangaphakathi luyi-polyethylene.Ngeke kube yinkinga ukuphuza ngemva kokufudumala.
Izikhwama zepulasitiki ezinombala azikupakishi ukudla okuvela kwamanye amazwe: Njengamanje, izikhwama eziningi zepulasitiki ezisetshenziswa abathengisi abathengisa imifino nezithelo emakethe zikhanya kancane futhi zimhlophe, kodwa futhi zibomvu, zimnyama, futhi ziphuzi, ziluhlaza, futhi ziluhlaza okwesibhakabhaka.Izikhwama zepulasitiki zisetshenziselwa ukupakisha ukudla okuphekiwe kanye nokudla okulula ukuze kusetshenziswe ngokuqondile.Kungcono ukungasebenzisi izikhwama zepulasitiki ezinemibala.Kunezizathu ezimbili: Okokuqala, izingulube ezisetshenziselwa ukudaya izikhwama zepulasitiki zinokungena okuqinile nokuguquguquka, futhi zizophuma kalula lapho zichayeka kuwoyela nokushisa;uma kuwudayi wemvelo, uzophinda ube nama-hydrocarbons anephunga elimnandi.Okwesibili, izikhwama eziningi zepulasitiki ezinemibala zenziwe ngamapulasitiki agaywe kabusha.Ngenxa yokuthi amapulasitiki agaywe kabusha aqukethe ukungcola okwengeziwe, abakhiqizi kufanele bengeze ama-pigments ukuze bawamboze.
Ukubona kanjani ukuba khona kwezikhwama zepulasitiki ezingenabo ubuthi: izikhwama zepulasitiki ezingenabo ubuthi zimhlophe qhwa, zicwebezela, noma azinambala futhi zisobala, ziyagobeka, zibushelelezi lapho uzithinta, futhi zinengcina phezulu;Izikhwama zepulasitiki ezinobuthi ziguqubele noma ziphuzi ngokukhanyayo ngombala, Ziqinile uma uzithinta.
Indlela yokuhlola amanzi: Faka isikhwama sepulasitiki emanzini bese usicindezela ngaphansi kwamanzi.Isikhwama sepulasitiki esingenabo ubuthi sinamandla adonsela phansi amancane athile futhi singavela.Isikhwama sepulasitiki esinobuthi sinamandla adonsela phansi amakhulu athile kanye nosinki.
Indlela yokuthola ukunyakazisa: bamba ingxenye eyodwa yesikhwama sepulasitiki ngesandla sakho bese usixhawula ngamandla.Lezo ezinomsindo opholile azinabo ubuthi;labo abanomsindo ongacacile banobuthi.
Indlela yokubona umlilo: izikhwama zepulasitiki ze-polyethylene ezingenabuthi ziyavutha, ilangabi liluhlaza okwesibhakabhaka, indawo engenhla iphuzi, futhi iconsa njengezinyembezi zekhandlela lapho livutha, inephunga likapharafini, futhi inentuthu encane;Izikhwama zepulasitiki ze-PVC ezinobuthi azikwazi ukuvutha futhi zishiya umlilo.Kuyacinywa, ilangabi liphuzi, phansi kuluhlaza, kuthambile futhi kungadonswa, ngephunga elimnandi le-hydrochloric acid.
