Ⅰ Izinhlobo zezikhwama zepulasitiki
Isikhwama sepulasitiki siyinto ebonakalayo ye-polymer, ngoba yasungulwa, kancane kancane iba yingxenye ebalulekile yempilo yabantu yansuku zonke ngenxa yokusebenza kwayo okuhle. Izidingo zansuku zonke zabantu, isikole kanye nezinto zomsebenzi ngakho konke kunesithunzi sepulasitiki. Hhayi kuphela ezidingekayo nsuku zonke, ipulasitiki nayo isetshenziswa kabanzi kwizimboni ezahlukahlukene ezinjengezokwelapha nokwakha. Ikakhulu, izikhwama zepulasitiki, ezikhanyayo ngesisindo, ezinkulu emandleni futhi zingagcina izinto ezahlukahlukene, ziye zaba umsizi obaluleke kakhulu futhi obalulekile ezimpilweni zabantu. Nazi ezinye zezigaba ezahlukahlukene zezikhwama ezenziwe ngopulasitiki.
Isikhwama se-1.vest
Ngoba ukwakheka kwezikhwama ezithile zepulasitiki kanye nokuphila kwansuku zonke kwabantu kugqoke i-undershirt kufana kakhulu, ngakho-ke abantu bazoyibiza ngokuthi isikhwama esingaphansi komhlaba, singabizwa nangokuthi isikhwama se-vest. Lolu hlobo lwesikhwama luzosebenzisa impahla ebizwa nge-po njengezinto eziphambili zokukhiqiza. Ngoba inqubo yokukhiqiza yesikhwama seVest ilula futhi iguquguqukayo, ingasetshenziswa ezitolo ezinkulu, izitolo ezinkulu, izitolo ezilula, izimakethe ezithengiswayo kanye nezinye zezindawo ezibalulekile empilweni yansuku zonke. Kodwa-ke, ngenxa yenkinga yezikhwama eziphansi zokwakha, okuholele ekungcoleni okukhulu kwemvelo, ngemuva kokuvinjelwa kokuvinjelwa kobuso, izwe laqala ukukhawula nokuvimbela ukukhiqizwa kanye nokukhiqizwa kwalokhu kuvinjelwe okunjalo.
Izikhwama ze-2.Cring
Lesi sikhwama sihlukile esikhwameni esingaphansi komhlaba, senziwa ngezinto ezingezona ezinobuthi, ezingangcolisi, ziphephile futhi zihlanzekile, ngeke zibangele ukungcoliswa okukhulu. Ngaphezu kwalokho, isikhwama seTote sivame ukusetshenziswa ezingutsheni, izipho, izipho kanye nokunye ukubukeka okuhle, imfashini epakisha futhi ebukeka kahle, kulula ukuyiphatha, ithandwa ngabantu.
3. Izikhwama ezinamathela
Izikhwama ezinamathela ezinamathela futhi zibizwa ngokuthi izikhwama ezinamathele, izikhwama zepulasitiki ezinamathela, i-OPP, pe nezinye izinto zokwenziwa kwezinto eziphambili. Ngenxa yomphumela omuhle wokuphrinta wezikhwama ezinamathela, ingaphrinta amaphethini ahlukahlukene, ngakho-ke ukukhiqizwa kanye nokusebenza kwezitshalo kube yindawo yokudla, okulula ukuklebhula, ekukhiqizeni izikhwama eziningi zokudla, ukukhiqizwa okujwayelekile kokuvalwa kwezikhwama.
Kunezinhlobo eziningi eziningi zezikhwama zepulasitiki, kuya ngokuthi kuzovela kuziphi izici zokuhlukaniswa.
Izinhlobo ezijwayelekile zezinto zokwakha
.
Izikhwama zepulasitiki, izikhwama zokupakisha zepulasitiki ziye zaba yizinto ezibalulekile empilweni yabantu, izikhwama zepulasitiki zamanje, izikhwama zokukhiqiza, ukukhiqizwa kwezikhwama zepulasitiki, ukukhiqizwa kwezikhwama zepulasitiki ngokuvamile kuzokhetha izinto ezisetshenziswa kaningi?
Okokuqala, i-polyethylene inani elikhulu kakhulu lezikhwama zepulasitiki, imikhiqizo yepulasitiki, impahla ebaluleke kakhulu, okwamanje iyisikhwama sokudla esikahle kakhulu sokudla, imakethe yezikhwama zokupakisha zokudla zivame ukwenziwa ngezinto ezibonakalayo. I-polyethylene Light and Transparent, inezinzuzo ezifanele umswakama, omoya ophefumulayo, ophefumulayo, i-ALKALI, i-Alkali, i-ALkali, i-ALkali, i-ALKALI, futhi ayinambitha, ayinambitha, ayinambitha, ayinambitha, ngokuhambisana namazinga okupakisha wokudla.
Okwesibili, i-polyvinyl chloride / pvc, njengamanje i-polyethylene yesibili emhlabeni ngemuva kwe-polyethylene, izikhwama zePVC, amathikithi, amathikithi kanye nezinye izembozo zokufaka nokuhlobisa, njll.
Okwesithathu, i-low-density polyethylene iyinani elikhulu kakhulu lemboni yokuphrinta yepulasitiki emazweni ahlukahlukene, elilungele indlela yokubumba yokubumba yokucubungula amafilimu akwatulur, alungele ukupakishwa kokudla, ukupakishwa kwemikhiqizo yansuku zonke, ukupakishwa kwemikhiqizo ye-fiber, njll.
Okwesine, i-polyethylene ephezulu, ukushisa kanye nokumelana nomusi, ukumelana okubandayo, umswakama, umswakama, ukusebenza kwe-polyethylene, futhi akulula ukuphula, impahla evamile yezikhwama zepulasitiki.
Ifilimu lesihlanu, elenzelwe i-piaxed polypropylene, amandla ayo, amandla okugoqa, ukuqina komoya, ukuvezwa komswakama okungcono kunefilimu evamile, kutholakale kabusha ngemuva kokuphrinta okugqamile futhi kube yinto ebalulekile yokupakisha okuguquguqukayo kwepulasitiki.
Ifilimu lesithupha, i-Shrink film futhi iyisigatshana esivamile sezikhwama zokufaka ipulasitiki, ukusetshenziswa kwemisebe okushisayo kuzoncipha, ngemuva kokushiswa kwemisebe yokushisa kusongwe kakhulu ezimpahleni ezihlanganisiwe, futhi kungagcinwa isikhathi eside.
Lezi yizikhwama zepulasitiki, izikhwama zokupakisha zepulasitiki, izikhwama ezihlanganisiwe, izikhwama ze-vacuum nezinye izinto ezijwayelekile zemikhiqizo yepulasitiki, ukuthuthukiswa kwezobuchwepheshe kanye nemvelo enobungani, imikhiqizo eluhlaza okonakele, imikhiqizo yepulasitiki izoba yisiqondiso esizayo sentuthuko nezitayela.
Isiphetho
Sizogcizelela ukuhlinzeka ngemikhiqizo engcono nensizakalo engcono kumakhasimende ethu.Uma kunemininingwane eminingi ngemikhiqizo ofuna ukuyazi, sicela uthumele umbuzo kithi noma ungeze i-US WhatsApp, sizokuphendula ngokushesha. Siyethemba ukuthi singakwazi ukuthola ubuhlobo obuhle nawe abafunda le ndatshana. Ngiyabonga ngokufunda lapha.
