Ⅰ Iintlobo zeengxowa zeplastiki
Isingxobo sePlastiki sisixhobo sokwenziwa kwepolymer, ukusukela oko yasungulwa, ngokuthe ngcembe ibe yinxalenye ebalulekileyo yobomi bemihla ngemihla yabantu ngenxa yokusebenza kwayo okugqwesileyo. Iimfuno zabantu zemihla ngemihla, izixhobo zesikolo nezomsebenzi njalo njalo zonke zinethunzi leplastiki. Hayi kuphela kwiimfuno zemihla ngemihla, iplastiki isetyenziswa ngokubanzi kumashishini ahlukeneyo afana nezonyango kunye nokwakha. Ngokukodwa, iingxowa zeplastiki, ezinobunzima obunzima, ubukhulu obukhulu kwaye zinokugcina izinto ezahlukeneyo, ziye zaba ngumncedisi obalulekileyo kunye nobalulekileyo ebomini babantu. Nazi ezinye zeentlobo ezahlukeneyo zeengxowa ezenziwe ngeplastiki.
1.Ivest bag
Ngenxa yokuba imilo yeengxowa zeplastiki kunye nobomi bemihla ngemihla babantu banxiba ihempe yangaphantsi iyafana kakhulu, ke abantu baya kuyibiza ngokuba yingxowa yangaphantsi yehempe, ikwanokuthiwa yivest bag. Olu hlobo lwengxowa luya kusebenzisa ngokubanzi izinto ezibizwa ngokuba yi-PO njengeyona nto iphambili yokuvelisa. Ngenxa yokuba inkqubo yokuvelisa ingxowa ye-vest ilula kwaye iyaguquguquka, inokusetyenziswa kwiivenkile ezinkulu, kwiivenkile ezinkulu, kwiivenkile ezithengisa izinto eziluncedo, iivenkile ezithengisa izinto ezithengiswayo kunye nezinye iindawo, ngoko yakha yaba yenye yezinto ezibalulekileyo kubomi bemihla ngemihla babantu. Nangona kunjalo, ngenxa yengxaki yeengxowa zangaphantsi kwempahla ekrwada, ekhokelela kungcoliseko lwendalo esingqongileyo, emva kokuphunyezwa kokuvalwa kweplastiki, ilizwe laqala ukunqanda kunye nokuvalwa kwemveliso kunye nokuveliswa kwentsimbi enjalo.
2.Ukuthwala iibhegi
Esi sikhwama sahlukile kwisingxobo sehempe sangaphantsi, senziwe ngezinto ezingeyotyhefu, ezingangcolisi, ezikhuselekileyo nezicocekileyo, aziyi kubangela ungcoliseko olukhulu. Ngaphezu koko, ibhegi ye-tote isetyenziswa ngokubanzi kwiimpahla, izipho, izinto zokubhala kunye nezinye izinto ezintle, ukupakisha okusefashonini kunye nokubukeka kakuhle, ukuthwala okulula, okuthandwa ngabantu.
3.Iingxowa zokuzincamathelisa
Iingxowa zokuzibamba zikwabizwa ngokuba ziingxowa ezincangathi, iiplastiki ezizincamathelayo, i-OPP, i-PE kunye nezinye izinto zokuvelisa izinto eziphambili. Ngenxa yempembelelo entle yoshicilelo lweengxowa ezincamathelayo, zinokuprinta iipatheni ezahlukeneyo, ngoko ke imveliso kunye neplanti yokucoca iye yaba yipakethe yangaphandle yeemveliso ezininzi, njengokutya, ubucwebe, njl njl.
Zininzi ezinye iindidi zeengxowa zeplastiki, kuxhomekeke kwimiba yolwahlulo.
Ⅱ Iintlobo eziqhelekileyo zezinto
.
Iingxowa zeplastiki, iingxowa zokupakisha zeplastiki ziye zaba zizinto ezibalulekileyo kubomi bemveliso yabantu, iingxowa zeplastiki zangoku, iingxowa ze-PVC, iingxowa ezihlanganisiweyo, iingxowa zokufunxa, iingxowa zokupakisha ze-PVC, ifilimu yeplastiki kunye nezinye iintlobo zeemveliso zeplastiki ezisetyenziswa ngokuqhelekileyo kwimfuno yemarike, ngoko umthamo wemveliso nawo mkhulu kakhulu, kwimveliso kunye nokuveliswa kweengxowa zokupakisha zeplastiki, ngokuqhelekileyo zeziphi iiplastiki eziza kusetyenziswa ngokubanzi?
Okokuqala, i-polyethylene sesona sixa sikhulu seengxowa zeplastiki, iimveliso zeplastiki, ezona zinto zibalulekileyo, okwangoku yeyona nto ifanelekileyo yengxowa yokutya emhlabeni, intengiso yeengxowa zokupakisha ukutya ngokubanzi zenziwe ngezinto. I-polyethylene ukukhanya kunye nokungafihli, inobungqina obufanelekileyo bokufuma, i-oxygen-resistant, i-asidi-resistant, i-alkali-resistant, ukutywinwa kobushushu kunye nezinye izinto eziluncedo, kunye ne-non-toxic, engenancasa, engenavumba, ngokuhambelana nemigangatho yezempilo yokupakisha ukutya.
Okwesibini, i-polyvinyl chloride / i-PVC, ngoku yeyesibini kwiintlobo zeplastiki ezinkulu zehlabathi emva kwe-polyethylene, lolona khetho lufanelekileyo kwiingxowa zokupakisha zeplastiki, iingxowa ze-PVC, iingxowa ezihlanganisiweyo, iingxowa ze-vacuum, zingasetyenziselwa iincwadi, iifolda, amatikiti kunye namanye amaqweqwe okupakisha kunye nokuhombisa, njl.
Okwesithathu, i-polyethylene ephantsi koxinaniso lolona luhlu likhulu lwemveliso yoshicilelo lweplastiki kumazwe ahlukeneyo, ilungele ukuvuthela indlela yokusetyenzwa kwiifilimu ze-tubular, ezilungele ukupakishwa kokutya, ukupakishwa kweemveliso zemichiza yemihla ngemihla, ukupakishwa kweemveliso zefayibha, njl.
Okwesine, i-polyethylene ephezulu, ubushushu kunye nokumelana nobushushu, ukuchasana nokubanda kunye neqhwa, umswakama, igesi, ukusebenza kwe-insulation, kwaye akulula ukuphula, amandla e-polyethylene ephantsi kabini, yinto eqhelekileyo kwiingxowa zeplastiki.
Okwesihlanu, ifilimu ye-polypropylene ejolise kwi-biaxially, amandla ayo omatshini, amandla okugoba, ukuxinana komoya, umqobo wokufuma ongcono kunefilimu yeplastiki eqhelekileyo, ngenxa yokubonakala kwefilimu yeplastiki ihle kakhulu, umbala oveliswe emva kokushicilela okuqaqambileyo kunye nokuhle, yinto ebalulekileyo yokupakishwa kweplastiki eguquguqukayo.
Okwesithandathu, ifilimu ecuthayo ikwayindawo eqhelekileyo yeengxowa zokupakisha zeplastiki, ezisetyenziswa kunyango lomoya oshushu okanye imitha ye-infrared iya kuncipha, emva kokuba unyango lobushushu luhlanganiswe ngokuqinileyo kwiimpahla ezipakishweyo, amandla okunciphisa afikelela kumlinganiselo wawo ophezulu kwinqanaba lokupholisa, kwaye unokugcinwa ixesha elide.
Ezi iingxowa zeplastiki, iingxowa ukupakisha iplastiki, iingxowa composite, iingxowa vacuum kunye nezinye izinto eziqhelekileyo iimveliso zeplastiki, kunye nophuhliso lobugcisa kunye nenkqubela phambili eqhubekayo, friendly ngakumbi kokusingqongileyo, iingxowa zeplastiki eziluhlaza ngokusingqongileyo, iimveliso zeplastiki ziya kuba ulwalathiso lwekamva lophuhliso kunye neendlela.
