Ngophuhliso loqoqosho lwemarike, ukhuphiswano lwempahla yorhwebo luya lusiba lubi kakhulu.Ngelixa ephucula umgangatho wemveliso, amashishini anyusa imisebenzi encedisayo yeemveliso kwaye azabalazela ukuveliswa kwezinto ezintsha, izinto ezintsha kunye nobuhle.Kuye kwaba yindlela entsha yokhuphiswano lwemveliso.Iimveliso zeplastiki ezinuka kamnandi yenye yazo.
Kukongezai-arhente yesiqholokwinkqubo yokubumba imveliso kunye nokulungiswa, ukuze iplastiki kunye nezinye iimveliso zikhuphe ivumba elimnandi xa zisetyenziswa, zinike abantu imvakalelo entsha, ekhululekile kunye nentsha, kwaye igqume ivumba elikhethekileyo elikhoyo kwi-resin okanye elenziwe kwinkqubo yokucubungula.Ukwandisa ixabiso lokusetyenziswa kweemveliso zeplastiki kunokuvuselela umnqweno wabathengi wokuthenga, ukuze bafezekise injongo yokuphumelela ngokumangalisayo kukhuphiswano olunzima lwemarike.
I-aromatic masterbatch ngumxube oxubene kakhulu neekhemikhali ezinuka kamnandi ezisasazwe ngokufanayo kwisiseko se-thermoplastic resin.Iiplastiki ezisebenza ngokufanelekileyo eziya kuthi ziqulunqwe ikakhulu yiresin ephetheyo, isiphuculisi sencasa kunye nesongezo.Ngefomula ethile kunye neteknoloji yokucubungula, incasa isasazwe ngokulinganayo kwiiplastiki ezithwalayo.Iiplastiki ziipholima eziphezulu zemolekyuli ezinobunzima obukhulu bemolekyuli kunye nesithuba esibanzi seemolekyuli.Kwisakhiwo semolekyuli yeeplastiki, kukho imimandla yekristale enolungelelwaniso oluqhelekileyo lweeamolekyuli, imimandla ye-amorphous enocwangco, kwaye ezinye zikwanamaqela e-polar, anceda ekungeneni amacandelo asebenzayo ezinto zokuphucula incasa kwiimolekyuli zeplastiki ngeendlela zomzimba okanye zekhemikhali. yenza i-multiphase enesakhiwo esisondeleyo phakathi kweziphuculi zencasa kunye neepolima.Ngenxa permeability kunye nokuguquka kwezinto ephantsi molekyuli, Kwaye ukuhambelana, ukuzei-arhente yesiqholokwiplastiki ngokuqhubekayo isasazeke ukusuka kugxininiso oluphezulu ukuya kugxininiso oluphantsi, kwaye emva koko iguquke ukusuka kumphezulu ukuya kokusingqongileyo, ikhupha ivumba elimnandi, ukuze kufezekiswe injongo yokusasazwa kwevumba lexesha elide.
i-arhente yesiqhololelona candelo liphambili le-masterbatch yeplastiki enevumba elimnandi.Yinto enuka kamnandi esetyenziselwa ukwandisa okanye ukuphucula ivumba lezinto.Ngokwesakhiwo sayo, inokwahlulwa ngokweester, iialcohol, aldehydes kunye ne-carboxylic acid.Ngenxa yeentlobo ezahlukeneyo, ukumelana nobushushu kunye nokuhambelana ne-resin nazo zihluke.Ukucutshungulwa kunye nokushisa okubunjwa kwee-resin eziqhelekileyo kungaphezulu kwe-150 ° C. Ngoko ke, kufuneka kukhethwe ngokumelana nokushisa okulungileyo, akulula ukusabela nge-resin kunye nezinye izongezo, i-dosage encinci, akukho tyhefu, kunye nokuhambelana okuthile kunye ne-base resin.
