Kupwanya chirema chirema chakajairika padhuze negedhi mune jekiseni molding hurema.Nekudaro, vanhu vazhinji vakavhiringika, havakwanise kuona chikanganiso kana kuita zvikanganiso zvekuongorora.Nhasi, tichajekesa.
Iyo inoratidzirwa nekutsemuka kunopenya kubva kugedhi kuenda kune periphery, iyo yakadzika uye kazhinji pachena.Mukuwedzera, haisi iyo kuputika, asi chikonzero chekuputika ndeye anisotropy yezvinhu zvakaoma.
Munguva yejekiseni reglue pagedhi repakati, iyo longitudinal kuyerera simba (tensile simba) yechinhu chikuru, nepo inochinjika yekuyerera simba (tensile simba) idiki.Kushungurudzika kunokonzerwa ne shrinkage kuchakwevera chigadzirwa kuti chiputse, uye kuputsika kunofanira kutanga panzvimbo isina simba, kureva, nzvimbo yakachinjika yezvinhu pedyo negedhi nekunetseka kukuru kwemukati.
The crack defect idambudziko rakakomba rinooneka, risingabviri kupfuura, saka rinofanira kugadziriswa.Pfungwa yacho ndeiyi inotevera:
1. Nezvezvinhu
Kuomarara kwechinyorwa ndicho chikonzero chikuru cheiyo chatter mamaki, saka kana paine maitiro akareba ezvigadzirwa zvakakura, edza kusasarudza zvinhu zvakanyanya kuomarara uye zvine yakaderera elongation panguva yekuzorora, seGPPS, AS, nezvimwe.
Muzvishandiso zvakajairika, kurongeka kwekusimba kubva kune isina simba kusvika kune yakasimba, uye mukana wekuitika kwekutsemuka kwekudengenyeka kubva padiki kusvika kuhombe ndeye: PE=>TPU=>PP=>PC=>ABS=>PA=>PVC=>PET=>POM=>PMMA=>AS=>PS.
Kazhinji, zvishandiso zvine mapoka anochinjika zvinogona kuvandudza iyo vibration pateni.Semuenzaniso, rubber materials, SEBS, EVA, K zvinhu zvinobatsira.
2. Nezve mold
Iyo gedhi dhizaini yejekiseni moldndiyo kiyi.Kazhinji kutaura, pasi pechimiro chine kushushikana kukuru kwemukati uye kuyerera kwenguva refu, iyo gedhi vibration pateni iri nyore kuitika.Naizvozvo, kune zvigadzirwa zvakakura, zviri nyore kutora chimiro chemasuwo akawanda uye yakafara magedhi kudzikisa kurabha kudyisa kuramba uye kufambisa kuyerera.
Kazhinji kutaura, gedhi repoindi riri nyore kuoneka mitsara yevibration.Side gedhi, fan gedhi uye lap gedhi zvakaderera zvishoma.Asi mamwe masuwo, senge submersible gedhi uye diaphragm gedhi, haazoshandiswi muzvivakwa zvakadaro.Nekuti zvizhinji zvezvigadzirwa zvine mitsetse yevibration zvigadzirwa zviri pachena, uye hapana chikonzero chekushandisa diving ports kana diaphragm ports.
3. Nezve ma paramita: kuyerwa kwemaparamendi ekugadzirisa iwo chatter mamaki ndeiyi:
① Inononoka kupfura kumhanya uye yakaderera kupfura kumanikidza
②Nguva pfupi yekumanikidza
③Tembiricha yekuumbwa inofanirwa kunge yakakwira, senge PS zvinhu.Iyo tembiricha yekuumbwa inogona kuiswa kune 60 madhigirii.
4. Pfupiso
Kupwanya idambudziko rakajairika mukugadzirwa kwezvinhu zvinoonekera zvakagadzirwa neGPPS zvinhu.Kana isu tikasateerera nzira dzekurapa, zvinopfuura 50% zvehurema kana zvese zvingave zvisina kunaka.Chete nekugona nzira dziri pamusoro apa tinogona kubvisa zvikanganiso uye tive nechokwadi chekugadzikana uye chemhando yepamusoro kugadzirwa.
