Nantoni na enokuphucula iimpawu zokuqala ze-resin ngokusebenzisa umzimba, oomatshini kunye nemiphumo yeekhemikhali inokubizwaukuguqulwa kweplastiki.Intsingiselo yokuguqulwa kweplastiki ibanzi kakhulu.Ngexesha lenkqubo yokuguqulwa, zombini utshintsho lomzimba kunye neekhemikhali lunokuyifikelela.

Iindlela eziqhelekileyo ezisetyenziswayo zokuguqulwa kweplastiki zezi zilandelayo:

1. Yongeza izinto ezilungisiweyo

a.Yongeza i-molecule encinci ye-inorganic okanye i-organic matter

Izongezo ze-inorganic ezifana nezihluzi, ii-agent zokuqinisa, ii-retardants zomlilo, ii-colorants kunye ne-nucleating agents, njl.

Izongezo ze-Organic ezibandakanya i-plasticizers, i-organotin stabilizers, i-antioxidants kunye ne-organic flame retardants, i-Degradation additives, njl.

b.Ukongeza izinto zepolymer

2. Ukuguqulwa kwemilo kunye nesakhiwo

Le ndlela ijolise ikakhulu ekuguquleni ifom ye-resin kunye nesakhiwo seplastiki ngokwayo.Indlela eqhelekileyo kukutshintsha i-crystal state yeplastiki, i-crosslinking, i-copolymerization, i-grafting kunye nokunye.Ngokomzekelo, i-styrene-butadiene graft copolymer iphucula impembelelo yezinto ze-PS.I-PS isetyenziswa ngokuqhelekileyo kwizindlu zeTV, izixhobo zombane, izibambi zokubhala iibhola, izibane kunye neefriji, njl.

3. Ukuguqulwa kweCompound

Ukuguqulwa okuhlanganisiweyo kweeplastiki yindlela apho iileya ezimbini okanye ngaphezulu zeefilimu, amaphepha kunye nezinye izinto zidityaniswe kunye ngokunamathelisa okanye ukunyibilika okutshisayo ukwenza ifilimu, iphepha kunye nezinye izinto.Kwishishini lokupakisha izimonyo, iityhubhu zeplastiki zokuthambisa kunyeiityhubhu ezidibeneyo ze-aluminium-plastikizisetyenziswa kule meko.

4. Ukuguqulwa komphezulu

Injongo yokuguqulwa komphezulu weplastiki ingahlulwa ibe ngamacandelo amabini: enye isetyenziswe ngokuthe ngqo ukuguqulwa, enye isetyenziswe ngokungathanga ngqo ukuguqulwa.

a.Isetyenziswe ngokuthe ngqo ukuguqulwa komphezulu weplastiki kubandakanya isicwebezelisi somphezulu, ukuqina komphezulu, ukumelana nokunxiba komphezulu kunye nokukhuhlana, ukuchasana nokuguga komphezulu, ukubuyiswa komlilo, ukuhanjiswa komphezulu kunye nomqobo womphezulu, njl.

b.Ukusetyenziswa ngokungathanga ngqo kokuguqulwa komphezulu weplastiki kubandakanya ukuguqulwa kokuphucula ukunyanzeliswa komphezulu weplastiki ngokuphucula ukunamathela, ukuprintwa kunye nokunyanyiswa kweeplastiki.Ukuthatha imihlobiso ye-electroplating kwiplastiki njengomzekelo, kuphela ukukhawuleza kokugquma kwe-ABS kunokuhlangabezana neemfuno zeeplastiki ngaphandle konyango lomphezulu;Ngokukodwa kwiiplastiki ze-polyolefin, ukukhawuleza kokugquma kuphantsi kakhulu.Ukuguqulwa komphezulu kufuneka kuqhutywe ukuphucula ukukhawuleza kokudibanisa kunye nokwaleka phambi kwe-electroplating.

Oku kulandelayo yiseti yezikhongozeli zezithambiso zesilivere ezikhazimle ngokupheleleyo: Udonga oluphindwe kabini 30g 50gingqayi yekhrimu, 30ml icinezelweibhotile yokulahlakunye ne50mlibhotile yokuthambisa.
