Yini ebanga ukugoba okungalungile kwezingxenye ezibunjwe ngomjovo wokubumba ipulasitiki

Kwadalwa ngo 01.13
Ngokuvamile, sihlangana nemikhiqizo ethile eyenziwe nge-plastiki yokufaka imouldi ethukile futhi eguquliwe. Yini ngempela edala lokhu? Ingabe usakhangela ekhanda lakho udidekile? Ingabe kuyinkinga yesakhiwo somkhiqizo, inkinga yemouldi, noma inkinga yezinto? Okwamanje, ake sihlole ndawonye imbangela ezivamile nezixazululo zokuguqulwa kwemikhiqizo ye-plastiki yokufaka imouldi.
  1. Ubangwa yisimo sokubunjwa, ukuhlanekezela okubangelwa yisimo sokubunjwa kungenxa yokwehluka kokuncipha kwezinhlangothi ezahlukene kanye nokwehluka kokuqina kodonga. Ngakho-ke, ukukhulisa izinga lokushisa lokubumba, ukuphakamisa izinga lokushisa lokuncibilika, ukwehlisa ingcindezi yokujova, nokuthuthukisa izimo zokugeleza zesistimu yokungena kunganciphisa umehluko ezingeni lokuncipha kwezinhlangothi ezahlukene. Noma kunjalo, ukushintsha izimo zokubumba kuvame ukuba nzima ukulungisa. Ezimweni ezinjalo, kuyadingeka ukushintsha indawo nenani lamagate, njengokujova kusuka kwenye ingxenye lapho kubunjwa izingxenye ezinde ezifana nezinduku. Kwesinye isikhathi, kuyadingeka ukushintsha ukuhlelwa kweziteshi zamanzi zokupholisa. Izingxenye ezinde, ezincane ezifana namashidi zivame ukuhlanekezela, futhi kwesinye isikhathi kuyadingeka ukushintsha umklamo wendawo yengxenye, njengokungeza izimbambo zokuqinisa ngemuva kohlangothi olubheke phezulu. Ukusebenzisa amathuluzi asizayo okupholisa ukulungisa lokhu kuhlanekezela kuvame ukusebenza. Uma ukulungisa kungenzeki, kuyadingeka ukushintsha umklamo wokubumba ipulasitiki. Phakathi kwalokhu, kubaluleke kakhulu ukuqinisekisa ukuthi ukuqina kodonga lomkhiqizo kuyahambisana. Ezimweni lapho lokhu kungenzeki, kuyadingeka ukukala ukuhlanekezela komkhiqizo, ukulungisa ukubumba ngokuphambene, nokukalibelela.
  2. Amayelana namapulasitiki e-crystalline, ama-resin anesilinganiso esiphakeme sokuncipha. Ngokuvamile, ama-resin e-crystalline afana ne-nylon, i-POM, i-PP, ne-PET abonisa ukuhlanekezela okukhulu kune-resin angewona e-crystalline afana ne-PMMA, i-PS, i-ABS, ne-PC. Ngaphezu kwalokho, ngenxa yokuqondiswa kwe-fiber kwamarezin agcizelelwe nge-glass fiber, ukuhlanekezela nakho kubalulekile, kuvame ukuholela ekuhlanekezeleni okunzima ukulungiswa ngenxa yebanga lokushisa elincane lokuncibilika. Ubukhulu be-crystalline bamapulasitiki e-crystalline buyahlukahluka ngezinga elihlukile lokupholisa, okungukuthi, ukupholisa okusheshayo kunciphisa ubukhulu be-crystalline futhi kunciphise ukuncipha kokubumba, kanti ukupholisa kancane kwandisa ubukhulu be-crystalline futhi kwandisa ukuncipha kokubumba. Indlela ekhethekile yokulungisa ukuhlanekezela kwamapulasitiki e-crystalline isebenzisa le ndlela, lapho indlela yangempela yokulungisa ihilela ukudala umehluko othile wokushisa phakathi kwezikhunta ezihambayo nezimile, okungukuthi, ukusebenzisa izinga lokushisa elibangela ukucindezeleka kolunye uhlangothi lwe-warpage, ngaleyo ndlela kulungiswe ukuhlanekezela. Kwesinye isikhathi lo mehluko wokushisa ungaba ngu-20°C noma ngaphezulu, kodwa kufanele usakazwe ngokulinganayo. Kumele kuqashelwe ukuthi lapho kuklanywa izingxenye ezibumbayo nezikhunta zamapulasitiki e-crystalline, uma izinyathelo ezikhethekile zokuvimbela ukuhlanekezela zingathathwa kusengaphambili, izingxenye ezibumbayo zingase zingasebenzi ngenxa yokuhlanekezela. Ezimweni eziningi, ukuhlanekezela akukwazi ukulungiswa ngokumane kuhlangatshezwane nezimo zokubumba ezishiwo ngenhla.
  3. Ukupholisa okunganele noma okungalingani, kanye nokukhipha ngaphambi kokuphola ngokuphelele kuvame ukubangela ukugobeka kwezingxenye ezibunjiwe ngenxa yamandla okucindezela wephini lokukhipha. Ngakho-ke, ukuphoqelela ukukhipha ngaphambi kokuphola ngokwanele kungaholela ekugobekeni. Isinyathelo sokulungisa ukukuvumela ukuphola ngokwanele ngaphakathi komgodi wesikhunta bese ukukhipha kuphela ngemuva kokuqina ngokuphelele. Kungenjalo, izinga lokushisa lesikhunta lingancishiswa futhi isikhathi sokuphola singanwetshwa. Kodwa-ke, kwezinye izimo lapho ukupholisa kwendawo yesikhunta kunganele futhi ukugobeka kungavimbeki ngaphansi kwezimo ezijwayelekile zokubumba, kufanele kucatshangelwe ukushintsha indlela yamanzi okupholisa, indawo yesiteshi samanzi okupholisa, noma ukwengeza izimbobo zokupholisa. Ngokukhethekile, kuyalulekwa ukucatshangelwa ukusebenzisa ukupholisa ngomoya esikhundleni sokupholisa ngamanzi.
  4. Ngenxa yokusetshenziswa kwezikhonkwane zokukhipha, ezinye izingxenye zingase zibonise izici ezimbi zokukhipha, okuholela ekugobeni lapho kukhiwa ngamandla kusetshenziswa izikhonkwane zokukhipha. Ezingxenyeni zepulasitiki ezingagobi kalula, lokhu kungase kubangele ukuqhekeka esikhundleni sokugoba. Ezingxenyeni ze-ABS ne-polystyrene, lokhu kugoba kubonakala ngokumhlophe endaweni ecindezelwe (bheka ukuqhekeka, iziqhekeza, iziqhekeza ezincane, nokumhlophe). Isixazululo ukuthuthukisa ukupholisha kwesikhunta ukuze kube lula ukukhipha. Ngezinye izikhathi, ukusebenzisa i-agent yokukhipha isikhunta kungase futhi kuthuthukise ukukhipha. Indlela eyisisekelo kakhulu yokuthuthukisa ukugaya i-core ukunciphisa ukumelana nokukhipha, noma ukwandisa i-draft angle, ukwengeza izikhonkwane zokukhipha ezindaweni lapho ukukhipha kunzima, njll. Ukushintsha indlela yokukhipha kubaluleke kakhulu.
  5. Ezikhunjweni zamapulasitiki ezincane noma imikhiqizo enezidingo ezikhethekile zokusebenza kwesakhiwo, kunzima kakhulu ukuxazulula inkinga kusuka esikhunjini uqobo noma epulasitiki uqobo. Singakwazi futhi ukwenza izinto zokubamba ukulungisa isimo somkhiqizo ngemuva kokubunjwa komjovo, bese sisebenzisa izinto zokubamba ukubamba umkhiqizo kuze kube yilapho usubanda ngokuphelele. Enye indlela elula ukubeka umkhiqizo olungisiwe ethuluzini lokulungisa, engeza izisindo endaweni egobile, kodwa kuyadingeka ukucacisa isisindo sezisindo nokubekwa kwazo. Noma ubeke umkhiqizo ogobile esiqondiseni bese uwufaka emanzini ashisayo eduze kwezinga lokushisa lokuhlanekezela komkhiqizo. Vele uwuqondise ngesandla, kodwa qaphela ukuthi ungasebenzisi amanzi ashisayo kakhulu, ngaphandle kwalokho kuzobangela ukuhlanekezela okubi kakhulu komkhiqizo. Kodwa-ke, le ndlela ayinconywa, njengoba ukucubungula ngesandla kuthatha isikhathi esiningi futhi kusebenzisa izinsiza eziningi kune-automation yemishini, futhi ukusebenza akulona iphakeme kakhulu, futhi ukulawula ikhwalithi akulula.
