Noma yini engathuthukisa izakhiwo zangempela ze-resin ngokusebenzisa imiphumela yomzimba, yemishini namakhemikhali ingabizwaukuguqulwa kwepulasitiki.Incazelo yokuguqulwa kwepulasitiki ibanzi kakhulu.Phakathi nenqubo yokuguqulwa, kokubili izinguquko zomzimba nezamakhemikhali zingayifinyelela.

Izindlela ezivame ukusetshenziswa zokuguqulwa kwepulasitiki zimi kanje:

1. Engeza izinto eziguquliwe

a.Engeza i-molecule encane ye-inorganic noma i-organic matter

Izithasiselo ze-inorganic ezifana nama-filler, ama-reinforcing agents, ama-flame retardants, ama-colorants nama-nucleating agents, njll.

Izithasiselo ze-organic ezihlanganisa ama-plasticizers, ama-organotin stabilizers, ama-antioxidants kanye ne-organic flame retardants, izithasiselo zokuwohloka, njll. Isibonelo, i-Topfeel yengeza izithasiselo eziwohlokayo kwamanye amabhodlela e-PET ukuze kusheshiswe izinga lokuwohloka nokonakala kwamapulasitiki.

b.Ukwengeza izinto ze-polymer

2. Ukuguqulwa kwesimo nesakhiwo

Le ndlela ngokuyinhloko ihloselwe ukuguqula ifomu le-resin kanye nesakhiwo sepulasitiki ngokwayo.Indlela evamile ukushintsha isimo se-crystal yepulasitiki, ukuxhumanisa, i-copolymerization, i-grafting nokunye.Isibonelo, i-styrene-butadiene graft copolymer ithuthukisa umthelela wezinto ezibonakalayo ze-PS.I-PS ivamise ukusetshenziswa ezindlini zama-TV, izinto zikagesi, izibambi zepeni lebhola, izithunzi zezibani neziqandisi, njll.

3. Ukuguqulwa kwenhlanganisela

Ukuguqulwa okuyinhlanganisela kwamapulasitiki kuyindlela lapho izingqimba ezimbili noma ngaphezulu zamafilimu, amashidi nezinye izinto zihlanganiswa ndawonye ngendlela yokunamathisela noma ukuncibilika okushisayo ukuze kwakhiwe ifilimu enezingqimba eziningi, ishidi nezinye izinto.Embonini yokupakisha yezimonyo, amashubhu epulasitiki yezimonyo kanyei-aluminium-plastic composite tubeszisetshenziswa kulesi simo.

4. Ukulungiswa kobuso

Inhloso yokuguqulwa kwendawo yepulasitiki ingahlukaniswa ngezigaba ezimbili: eyodwa isetshenziswa ngokuqondile ukuguqulwa, enye isetshenziswa ngokungaqondile ukuguqulwa.

a.Kusetshenziswe ngokuqondile ukuguqulwa kwendawo yepulasitiki okuhlanganisa ukucwebezela komhlaba, ukuqina kwendawo, ukumelana nokuguga nokungqubuzana, ukumelana nokuguga kwendawo, i-surface flame retardant, ukuguquguquka kwendawo kanye nokuvimbela indawo, njll.

b.Ukusetshenziswa okungaqondile kokuguqulwa kwendawo yepulasitiki kuhlanganisa ukuguqulwa ukuze kuthuthukiswe ukungezwani okungaphezulu kwamapulasitiki ngokwenza ngcono ukunamathela, ukuphrinta kanye nokufakwa kwepulasitiki.Ukuthatha imihlobiso ye-electroplating kupulasitiki njengesibonelo, ukushesha kokunamathela kwe-ABS kuphela okungahlangabezana nezidingo zamapulasitiki ngaphandle kokwelashwa kwendawo;Ikakhulukazi kumapulasitiki e-polyolefin, ukushesha kokunamathela kuphansi kakhulu.Ukuguqulwa kobuso kufanele kwenziwe ukuze kuthuthukiswe ukushesha kwenhlanganisela nokunamathela ngaphambi kwe-electroplating.

Okulandelayo isethi yeziqukathi zezimonyo ezicwebezela nge-electroplated esiliva: Udonga oluphindwe kabili 30g 50gimbiza kakhilimu, 30ml icindezelweibhodlela le-dropperkanye 50mlibhodlela lokugcoba.
