Inkcazo yeplastiki:
Iplastiki yinto enepolymer ephezulu njengeyona nto iphambili. Iqukethe i-resin synthetic kunye ne-fillers, i-plasticizers, i-stabilizers, i-lubricants, i-pigment kunye nezinye izongezo. Kukwimeko yolwelo ngexesha lokuvelisa kunye nokulungiselela ukuhambisa imodeli, Inika imilo eqinileyo xa kugqityiwe ukwenziwa. Eyona nto ingundoqo yeplastiki - intlaka zokwenziwa. "I-Resin" ibhekisa kwipolymer ephezulu eneemolekyuli engaxutywanga nezongezo ezahlukeneyo. I-resin i-akhawunti malunga ne-40% ukuya kwi-100% yobunzima bebonke beplastiki. Iipropathi ezisisiseko zeplastiki ikakhulu zimiselwe ziipropathi zentlaka, kodwa izongezo zikwadlala indima ebalulekileyo.
2. Izizathu zokuguqulwa kweplastiki:
Oko kubizwa ngokuba "kukuguqulwa kweplastiki" kubhekisa kwindlela yokongeza enye okanye ezingaphezulu izinto kwi-resin yeplastiki ukutshintsha ukusebenza kwayo kwasekuqaleni, ukuphucula imeko enye okanye ezingaphezulu, kwaye ngaloo ndlela kufezekiswe injongo yokwandisa ububanzi bayo besicelo. Izinto zeplastiki eziguqulweyo ngokudibeneyo zibizwa ngokuba yi "plastiki eguqulweyo".
Ukulungiswa kweplastiki kubhekisa ekutshintsheni iipropathi zezinto zeplastiki kwicala elilindelwe ngabantu ngokwasemzimbeni, imichiza okanye zombini iindlela, okanye ukunciphisa kakhulu iindleko, okanye ukuphucula iipropathi ezithile, okanye ukunika iiplastikhi Umsebenzi omtsha wezinto eziphathekayo. Inkqubo yokulungiswa inokwenzeka ngexesha lokumodareyitha kwe-resin eyenziweyo, oko kukuthi, ukuguqulwa kwamachiza, njengokukopishwa komgubo, ukufakelwa, ukudibanisa, njl njl, kungenziwa kwakhona ngexesha lokulungiswa kwentlaka yokwenziwa, oko kukuthi, ukuguqulwa komzimba, ukugcwalisa kunye nokudityaniswa kwepolymerization. Ukuxuba, ukuphucula, njl.
3. Iindidi zeendlela zokuguqula iplastiki:
1) Ukuqiniswa: Injongo yokwandisa ukuqina kunye namandla omathiriyeli kufezekiswa ngokudibanisa i-fibrous okanye i-flake fillers ezinje ngeglasi yefayibha, ifayibha yekhabhoni kunye nomgubo we-mica, njengeglasi yefayibha yenylon eqinisiweyo esetyenziswa kwizixhobo zamandla.
2) Toughening: Injongo yokuphucula ubungqongqo kunye nefuthe lamandla eplastiki kufezekiswa ngokudibanisa irabha, i-elastomer ye-thermoplastic kunye nezinye izinto kwiplastiki, ezinje nge-polypropylene ethambileyo esetyenziswa ngokufuthi kwiimoto, izixhobo zasekhaya kunye nokusetyenziswa kwemizi-mveliso.
I-3) Ukuxuba: ngokuxuba ngokufanayo izinto ezimbini okanye ezingaphezulu ezingahambelaniyo kumxube we-macro-ehambelanayo kunye nomxube wesigaba esahlukileyo ukuhlangabezana neemfuno ezithile ngokubhekisele kwiipropathi zomzimba kunye nezomatshini, iipropathi ezibonakalayo, kunye nepropathi yokuqhubekeka. Indlela efunekayo.
4) Ukuzalisa: Injongo yokuphucula iipropathi zomzimba kunye noomatshini okanye ukunciphisa iindleko kufezekiswa ngokongeza iifilthi kwiplastiki.
5) Olunye uhlengahlengiso: njengokusebenzisa iifilitha zokuhambisa ukunciphisa ukungahambelani kombane kwiplastiki; ukongezwa kwee-antioxidants kunye nokuzinzisa okulula ukuphucula ukuxhathisa kwemozulu kwezinto; ukongezwa kwee-pigment kunye nedayi ukutshintsha umbala wezinto eziphathekayo; ukongezwa kwezinto zokuthambisa zangaphakathi nangaphandle zokwenza umbandela Ukusebenza kokusebenza kweplastikhi ye-crystalline kuphuculwe; iarhente ye-nucleating isetyenziselwa ukutshintsha iimpawu ze-crystalline zeplastikhi ye-crystalline ukuphucula iipropathi zayo zoomatshini kunye nokubonakalayo.
