Ungaxazulula kanjani izinkinga zokubumba ezihlukanisayo ezihlukanisayo

Izinkinga zokubumba ezihlukanisa umjovo kanye nomthelela wenqubo yokubumba umjovo ekubonakaleni kwemikhiqizo ye-PP,uyakwazi ukuxazulula?
Namuhla ake sikhulume ngazo.
1. Imishini kagesi:
(1) Amandla okubamba we umshini wokubumba ayanele. Lapho ukhetha umshini wokubumba umjovo, amandla okubamba okulinganiselwe omshini kufanele abe phezulu kunokushuba okwakhiwa indawo eqagelwe isikhathi eside yomkhiqizo obunjiwe womjovo ngesikhathi sokujova. Uma kungenjalo izobangela ukwanda kwesikhunta kanye nokuhlukana kwamabhari angaphezulu..

(2) Idivayisi yokubopha isikhunta ayilungiswanga kahle, indlela yokuguqula ayiqondile, futhi ukubunjwa kwesobunxele nesokudla noma phezulu naphansi akulingani, futhi ukufana kwesikhunta akukwazi ukufezwa. Isenzakalo sokuthi uhlangothi olulodwa lwesikhunta luvalwe ngokuqinile kanti olunye uhlangothi aluxhunyiwe eduze. , Kuzoba khona ama-burrs ahlukene ngesikhathi sokujova. Ku

(3) Isikhunta ngokwaso asihambisani kahle, noma ukufakwa akufani, noma isifanekiso asihambisani, noma i-tension rod isatshalaliswa ngokulinganayo futhi ikhubazekile. Lokhu kuzodala ukuthi i-mold clamping ingaqini futhi ama-burrs angaphezulu azovela. Ku

(4) Indandatho engabuyi igqokwe kakhulu; intwasahlobo nozzle spring ihluleka; umgqomo noma isikulufu sigqokwe kakhulu; isistimu yokupholisa ye-inlet iyehluleka ukudala “ibhuloho” ukwenzeka; umthamo womjovo wesethi yomgqomo ayanele, umcamelo mncane kakhulu, njll. Kungase kubangele ukuthi ama-burrs angaphandle avele ngokuphindaphindiwe, futhi kufanele ilungiswe noma ishintshwe ngesikhathi.

2. Isici sesikhunta
Ukunemba okungalungile kwendawo ehlukanisa isikhunta. Ukungathathi hlangothi komgogodla wesikhunta kubangela izikhala lapho isikhunta sivaliwe, okuholela kuma-burrs endaweni ehlukanayo. Ku

3. Inqubo
(1) Ingcindezi yomjovo iphezulu kakhulu noma ijubane lomjovo lishesha kakhulu. Ngenxa yomfutho ophezulu kanye nesivinini esikhulu, amandla okuvula kwisikhunta ayanda futhi abangele ukukhanya. Isivinini somjovo kanye nesikhathi somjovo kufanele silungiswe ngokuhambisana nobukhulu bomkhiqizo. Umkhiqizo omncane kufanele ugcwaliswe ngokushesha ngesivinini esikhulu, futhi awukho umjovo ngemva kokugcwalisa; umkhiqizo owugqinsi kufanele ugcwaliswe ngesivinini esiphansi. Ku

(2) Umthamo wokudla oweqile udala ama-burrs endaweni ehlukanayo. Kubalulekile ukuqaphela ukuthi ungajovi incibilike kakhulu ukuze uvimbele ukucindezeleka, ukuze ukucindezeleka kungabi khona “agcwaliswe”, kodwa ama-burrs angaphezulu azovela. Lesi simo kufanele sixazululwe ngokwandisa isikhathi somjovo noma isikhathi sokubamba. Ku

(3) Ukushisa okuphezulu kakhulu komgqomo kanye ne-nozzle noma izinga lokushisa eliphakeme kakhulu lesikhunta kuzonciphisa i-viscosity yepulasitiki futhi kwandise i-fluidity.okuzobangela ama-burrs endaweni yokuhlukanisa ngaphansi kwesimo sokungena kahle esikhunjeni..
4. Mayelana nezinto zokusetshenziswa
(1) Uma i-viscosity yepulasitiki iphezulu kakhulu noma iphansi kakhulu, kungase kube nama-burrs angaphezulu okuhlukanisayo. Amapulasitiki ane-viscosity ephansi, njengenayiloni, i-polyethylene, i-polypropylene, njll., kufanele ikhulise amandla okubamba;

amapulasitiki anamanzi anamandla noma amapulasitiki azwela amanzi azonciphisa kakhulu i-viscosity yokugeleza emazingeni okushisa aphezulu futhi akhulise amathuba okuhlukanisa ama-burrs angaphezulu Kulawa mapulasitiki., kumelwe zomiswe kahle; i-viscosity yamapulasitiki ahlanganiswe nezinto eziningi ezigaywe kabusha nawo azokwehla, futhi uma kunesidingo, ugcwalise izingxenye ezigciniwe. Ipulasitiki

Uma i-viscosity yezinto ezibonakalayo iphezulu kakhulu, ukumelana nokugeleza kuzokwanda, futhi ukucindezela okukhulu emuva kuzokwandisa ukucindezela kwe-cavity, okuholela ekubambeni kwamandla anganele kanye nokukhiqiza ama-burrs angaphandle ahlukanisayo. Ku

(2) Ubukhulu bezinhlayiyana ezingalingani zezinto zokusetshenziswa zepulasitiki zizobangela inani lokudla lihluke, futhi ama-burrs angaphezulu azovela.

Umthelela we umjovo udini inqubo ku ukucaca kwemikhiqizo ye-PP
Ukungafihli kwemikhiqizo ye-polypropylene esobala elungiswe nge-ejenti esobala ye-nucleating ayihlobene kuphela nekhwalithi plastic impahla eluhlaza uqobo, kodwa futhi ihlobene eduze nokukhethwa kwezimo zenqubo yokubumba umjovo.

Ukuthola okungcono kakhulu umjovo udini Izimo zezinto zokusetshenziswa zisiza ekwandiseni amandla okukhanya wezinto ezingavuthiwe kanye nokuthola imikhiqizo esobala ye-polypropylene. Lokhu kunokubaluleka okuhle ezinkampanini zemikhiqizo yepulasitiki.

Izici ezinomthelela wokungafihli kwe-PP:

(1) Ukuphakama kwezinga lokushisa lokuncibilika, ukuphakama kwenkungu ye-polymer polypropylene engahleliwe ngaphandle kwe-nucleating agent esobala futhi kubi nakakhulu ukubonakala obala.

(2) Umthelela wezinga lokushisa elincibilikayo kuhaze we-copolymer polypropylene engahleliwe enezinhlobo ezahlukene zama-nucleating agents asobala ahlobene nezinhlobo zama-nucleating agents..

(3) Ngemikhiqizo engabonisa ngokugcwele umphumela wokulwa ne-reflection we-ejenti ye-nucleating esobala ekushiseni okuncibilika okuphansi, inkungu izokhuphuka kancane ngokukhuphuka kwezinga lokushisa elincibilikayo, kodwa ububanzi boshintsho bukhulu kunalelo le-agent engeyona i-nucleating. I-copolymer polypropylene engahleliwe incane kakhulu.

(4) Ukwehla kwezinga lokushisa kwesikhunta, ukwehla kwenkungu ye-polypropylene esobala futhi kuphezulu ukukhanya.

(5) Ijubane lomjovo ngokushesha, iphezulu inkungu ye-polypropylene esobala futhi iyancipha ukubonakala.

(6) Ngokunwetshwa kwesikhathi sokubamba, inkungu ye-polypropylene ebonakalayo iyancipha, futhi ngemva kokufinyelela umkhawulo, ihlala ingashintshile.

(7) Njengoba ingcindezi yokubamba ikhula, inkungu ye-polypropylene ebonakalayo iyancipha, kodwa uma ingcindezi yokubamba inkulu kakhulu, umkhiqizo uzoba ne-flash, futhi ukucindezeleka kwangaphakathi okusele komkhiqizo nakho kuzoba kukhulu uma kuqhathaniswa.
