Ukusebenza okubalulekile

1, Ukusebenza okungcono kukonke, amandla omthelela aphezulu, ukuqina kwamakhemikhali, izakhiwo ezinhle zikagesi.

2, Ukuhlanganisa okuhle ngengilazi ephilayo engama-372, eyenziwe ngezingxenye zepulasitiki ezinemibala emibili, futhi indawo engaphezulu ingaba yi-chrome-plated, ukwelashwa ngopende wesifutho.

I-3, kunomthelela omkhulu, ukumelana nokushisa okuphezulu, i-flame retardant, ethuthukisiwe, esobala namanye amazinga.

I-4, i-fluidity imbi kakhulu kune-HIPS, ingcono kune-PMMA, i-PC, njll., ukuguquguquka okuhle.

Ifanele ukwenza izingxenye ezijwayelekile zemishini, izingxenye ezingagugi, izingxenye zokudlulisela kanye nezingxenye zokuxhumana.

Ukusebenza kokubumba

I-1, impahla ye-amorphous, i-fluidity ephakathi, ukumuncwa komswakama, kufanele yomiswe ngokuphelele, izidingo ezingaphezulu zezingxenye zepulasitiki ezicwebezelayo kufanele kube isikhathi eside sokushisa ngaphambi kokumisa ama-80-90 degrees, amahora amathathu.

I-2, Kutuswa ukuthatha izinga lokushisa eliphakeme lempahla kanye nezinga lokushisa eliphakeme lesikhunta, kodwa izinga lokushisa lempahla liphezulu kakhulu futhi kulula ukubola.Ukuze uthole izingxenye zepulasitiki ezinembayo eziphezulu, izinga lokushisa lesikhunta kufanele libe ngama-degree angama-50-60, futhi ezingxenyeni zepulasitiki ezicwebezelayo ezikwazi ukumelana nokushisa, izinga lokushisa lesikhunta kufanele libe ngama-60-80 degrees.

3, Uma ufuna ukuxazulula inkinga yamanzi clamping, udinga ukuthuthukisa fluidity wendaba, thatha izinga lokushisa eliphezulu impahla, izinga lokushisa eliphezulu isikhunta, noma ushintshe izinga lamanzi kanye nezinye izindlela.

I-4, njengokwenza izinto zebanga elingamelana nokushisa noma ezingashisi ilangabi, isikhunta ngemuva kwezinsuku ezi-3-7 zokukhiqiza sizohlala sibolile sepulasitiki, okuholela ekubeni isikhunta sicwebezele, isikhunta sidinga ukuhlanzwa ngesikhathi, kuyilapho isikhunta sidinga ukwandisa indawo yokukhipha.

4, ipulasitiki ye-PP (i-polypropylene)

Amandla adonsela phansi athile: 0.9-0.91g/cm3

Ukuncipha kokubumba: 1.0-2.5%

Izinto ezibonakalayo

Ukuminyana okuncane, amandla, ukuqina, ubulukhuni nokumelana nokushisa kungcono kune-polyethylene yokucindezela okuphansi, ingasetshenziswa cishe ngama-degree angu-100.Izakhiwo zikagesi ezinhle kanye nokwahlukaniswa kwe-high-frequency akuthintwa umswakama, kodwa kuba brittle ezingeni lokushisa eliphansi futhi alikwazi ukumelana nesikhunta futhi kulula ukuguga.

Ilungele ukwenza izingxenye ezijwayelekile zemishini, izingxenye ezimelana nokugqwala kanye nezingxenye ezivikelayo.

Ukusebenza kokubumba

I-1, i-crystalline material, ukumuncwa komswakama kuncane, kulula ukuncibilika ukuphuka komzimba, ukuthintana isikhathi eside nokubola kwensimbi eshisayo.

2, fluidity omuhle, kodwa uhla shrinkage kanye shrinkage value likhulu, kulula ukwenzeka shrinkage, ukubola, deformation.

I-3, isivinini sokupholisa esisheshayo, uhlelo lokuthulula kanye nesistimu yokupholisa kufanele iphuze ukuqeda ukushisa, futhi unake ukulawula izinga lokushisa lokubumba.Isiqondiso sokushisa okuphansi kwezinto ezibonakalayo sisobala, ikakhulukazi ekushiseni okuphansi nokucindezela okukhulu.Lapho izinga lokushisa lesikhunta lingaphansi kwama-degree angu-50, izingxenye zepulasitiki azibushelelezi, kulula ukukhiqiza ukuhlangana okungalungile, ukushiya amamaki, futhi ngaphezu kwama-degree angu-90, kulula ukusonteka nokuguqulwa.

I-4, ukushuba kodonga lwepulasitiki kumele kube iyunifomu, gwema ukuntuleka kweglue, amakhona abukhali, ukuvimbela ukuhlushwa kokucindezeleka.

5, ipulasitiki ye-PS (i-polystyrene)

Amandla adonsela phansi athize: 1.05g/cm3

Ukuncipha kokubumba: 0.6-0.8%

Ukushisa kokubumba: 170-250 ℃

Izimo zokomisa: -

Ukusebenza okubalulekile

Ukufakwa kukagesi (ikakhulukazi i-high frequency insulation) kuhle kakhulu, akunambala futhi kusobala, izinga lokudlulisa ukukhanya lingokwesibili kuphela kunengilazi ephilayo, umbala, ukumelana namanzi, ukuzinza kwamakhemikhali kuhle.Amandla avamile, kodwa aqatha, akhiqiza kalula i-stress brittle crack, angazweli ku-benzene, uphethiloli nezinye izincibilikisi eziphilayo.

Ifanele ukwenza izingxenye ezivikelayo nezisobala, izingxenye zokuhlobisa kanye nezingxenye zamathuluzi amakhemikhali nezinsimbi zokukhanya.

Ukwakha ukusebenza

I-1, impahla ye-amorphous, ukumuncwa komswakama omncane, akudingeki ukuba yome ngokugcwele, akulula ukubola, kodwa i-coefficient yokwanda okushisayo inkulu, kulula ukukhiqiza ukucindezeleka kwangaphakathi.Ukugeleza okuhle, okutholakalayo ekubunjweni komshini wokujova ngesikulufu noma we-plunger.

I-2, izinga lokushisa eliphakeme lempahla, izinga lokushisa eliphakeme lesikhunta kanye nengcindezi ephansi yomjovo kufanelekile.Ukwelula isikhathi somjovo kunenzuzo ukunciphisa ukucindezeleka kwangaphakathi futhi kuvimbele ukuncipha nokuguqulwa.

I-3, etholakala ngezindlela ezihlukahlukene zesango, isango kanye ne-plastic arc uxhumano, ukuze ugweme ukulimala ezingxenyeni zepulasitiki lapho uya esangweni.I-slope ye-demoulding inkulu, i-ejection ilingana, ubukhulu bodonga bengxenye yepulasitiki bulinganayo, kungcono ukungabi nokufakwa, uma kukhona ukufakwa, kufanele kushiswe.
