Ngokombono wokubumba, isizathu esiyinhloko sokuqina kwezingxenye ezibunjiwe zomjovo wukuhlelwa kokuqondisa kwama-molecule angaphakathi, ukucindezeleka okusalela ngokweqile kwangaphakathi, njll. Uma izingxenye ezibunjiwe zomjovo zinemigqa yokufaka amanzi, isimo sizoba sibi kakhulu.
Ngakho-ke, kuyadingeka ukugcina izinga lokushisa eliphezulu lesikhunta kanye nezinga lokushisa elincibilikayo ukuze kuncishiswe ukonakala kwezingxenye ezibunjiwe zomjovo lapho ukhiqiza ezinkulu.izingxenye ezibunjiwe ngomjovo.Ngaphezu kwalokho, kuyasiza nokunciphisa ingcindezi ngokwandisa kahle ijubane lomjovo.Ngenxa yokuthi ijubane liphansi, ukuchithwa kokushisa kwe-glue kuncibilika kuzokwanda kakhulu, futhi izinga lokushisa lizokwehla kakhulu.Kuboshelwe ukudinga ukucindezela okukhulu komjovo weglue ukuze kugcwaliswe umgodi.
Ukuze kuqinisekiswe izinga lomkhiqizo ozinzile futhi ofanelekayo, ekuqaleni kokukhiqizwa, kusukela ekushiseni kwe-umjovo isikhuntaayikavuki, kungcono ukungasebenzisi izingxenye ezibunjiwe zomjovo wokuqala ezingama-20, ngoba zithambile, ikakhulukazi izingxenye ezibunjiwe zomjovo ezinokuqina okukhulu, njenge-fire retardant, kufanele zibe yizicucu ezingaphezu kuka-30.
Isimo sezulu siphinde sibe nomthelela omkhulu ekushwabaneni kwezingxenye ezinkulu ezibunjwe ngomjovo.Lapho isimo sezulu esibandayo sifika, sizothola ukuthi izingxenye eziningi ezibunjwe ngomjovo ezivame ukukhiqizwa, njengePP, i-ABS, i-PC, i-K materials nezinye izingxenye ezinokumelana nomthelela omuhle, ngokuzumayo ziba brittle.Ngezinye izikhathi ngisho nezingcezu ezincane zingase ziqhunyiswe, ngakho zivame ukubuyiselwa ngamakhasimende.
Ukuze kuqedwe umthelela wokucindezelwa okuyinsalela ngokweqile kwangaphakathi kanye nokuma kwamangqamuzana angathi sína ekushwabaneni kwezingxenye ezibunjiwe zomjovo, ukwelashwa ngokushisa kwezingxenye ezibunjiwe ngomjovo kuyisinyathelo esisebenzayo sokuvimbela ukonakala.
Ukuze kuqinisekiswe ukuthembeka komkhiqizo ebusika, uma ukwakheka komkhiqizo kuvumela, futhi zonke izivivinyo zifanelekile, izinto ezifanele nezimo ezihambisana nezinto zokusetshenziswa zengezwa ekukhiqizeni izinto zokusetshenziswa, njengenani elincane lempahla ye-EVA ku-PP. impahla, inani elincane lempahla ye-K ezintweni ze-HIPS, njll., okuyisixazululo esihle sokuvimbela ukonakala kwezingxenye ezibunjiwe ngomjovo.
Izizathu zokuqina kwezingxenye ezinkulu ezibunjwe ngomjovo:
1. Ukucindezela okuphezulu komjovo weglue;
2. Ngesikhathi sokugcwalisa isikhunta, izinga lokushisa lehla ngokushesha kakhulu;
3. Ama-molecule angaphakathi ahlelwa ngendlela, futhi ukucindezeleka kwangaphakathi okusele kukhulu kakhulu;
Izinyathelo ze-Anti brittleness:
1. Gcina izinga lokushisa eliphezulu lesikhunta kanye nezinga lokushisa elincibilikayo;
2. Khulisa kahle ijubane lomjovo weglue;
3. Izingxenye ezibunjiwe zomjovo zokuqala ezingama-20 akufanele zisetshenziswe;
4. Faka ukuhlolwa kwethonya lokushintsha kwezinga lokushisa;
5. Ukwelashwa kokushisa;
6. Gwema ukuthintana nokusondela kuncibilikisi ezonakalisayo noma indawo ezungezile;
7. Faka kahle izinto eziguquguqukayo ezihambisana nezinto zokusetshenziswa ekukhiqizeni izinto zokusetshenziswa.
