Amanzi asebhotileni aya ethandwa ngakumbi, kodwa ingxaki yevumba lamanzi okusela ebhotile ye-PET ithe ngokuthe ngcembe yatsala ingqalelo yabathengi.Nangona ingachaphazeli ucoceko kunye nempilo, isafuna ingqwalasela eyaneleyo kwiinkampani zokuvelisa, izinto kunye neenkampani ezithengisayo.
Amanzi ebhotile ye-PET akhiwe ngamanzi, ibhotile ye-PET kunye ne-cap yeplastiki.Amanzi awanambala kwaye akanavumba, anamalungu anuka kancinci anyibilikisiweyo, aya kuvelisa incasa engathandekiyo xa esetyenzisiwe.Ke, livela phi ivumba emanzini?Emva kophando oluninzi kunye novavanyo, abantu bafikelele kwisigqibo esibanzi: Ukongeza kwizinto ezishiyekileyo zokuhlamba iibhotile kunye nesibulali ntsholongwane, ivumba elimnandi emanzini livela ikakhulu kwizinto zokupakisha.Iimpawu eziphambili zezi:
1. Ivumba lezinto zokupakisha
Nangona izinto zokupakisha zingenavumba kwiqondo lobushushu begumbi, xa ubushushu bungaphezulu kwama-38°C ixesha elide, izinto ezincinci ze-molecular kwi-package materials ziyakwazi ukuguquguquka kwaye zifudukele emanzini, zibangele iphunga.Izinto ze-PET kunye nezixhobo ze-HDPE ezenziwe ngeepolymers zivakalelwa kakhulu kubushushu.Ngokuqhelekileyo, okukhona iqondo lobushushu liphezulu, kokukhona ivumba liba likhulu.Ekubeni ezinye izinto eziphakathi kunye neziphantsi zeemolekyuli zihlala kwi-polymer, kumaqondo aphezulu okushisa, i-volatilizes ivumba elingakumbi kunepolymer.Gwema ukuthutha kunye nokugcinwa phantsi kweemeko eziphezulu zokushisa ukuze ugweme ngokufanelekileyo ukuveliswa kokuvumba.
2. Ukuthotywa kwezongezo kwiibhotile zempahla ekrwada
Injongo ephambili yokongeza i-lubricant kukuphucula ukusebenza kokuvula i-cap cap kunye nokwenza kube lula kubathengi ukusela;ukongeza i-ejenti yokukhulula ukuququzelela ukukhululwa okugudileyo kwe-cap kwi-mold xa wenza i-cap;ukongeza umbala we-masterbatch ukutshintsha umbala we-cap kunye nokwahlula inkangeleko yemveliso.Ezi zongezo zidla ngokuqulatha i-amides enamafutha angaxutywanga, apho i-double bond C=C structure is easy oxidized.Ukuba ibonakaliswe kukukhanya kwe-ultraviolet, ubushushu obuphezulu, kunye ne-ozone, le bhondi ephindwe kabini inokuvulwa ukuze yenze umxube owonakeleyo: i-saturated kunye ne-unsaturated fatty acids, i-acetaldehyde, i-carboxylic acids, kunye ne-hydroxides, njl., ezinokunyibilika ngokulula emanzini kwaye zivelise ezahlukeneyo incasa.kunye nevumba.
3. Intsalela yevumba eyenziwe ngexesha lenkqubo yokwenza i-cap
Izinto ezisetyenziselwa ukwenza ii-caps zongezwa kunye nezongezo ezifana ne-lubricant.Ukwenza i-cap kubandakanya iinkqubo ezifana nokufudumeza kunye nesantya esiphezulu sokuvuselela oomatshini.Amavumba ngenxa yokulungiswa ahlala kwisiciko kwaye ekugqibeleni aya kufudukela emanzini.
Njengomvelisi owaziwayo webhotile, i-Mingsanfeng Cap Mold Co., Ltd. ibonelela abathengi ngezixazululo zebhotile ezidibanisa ukuyila, uphando kunye nophuhliso, imveliso, ukuthengisa kunye nenkonzo.
