Isikulufu singahlangabezana kanjani nokumelana nokugqoka kanye nezidingo zokucubungula ezinembayo?

Emkhakheni we-plastic extrusion kanye nokubunjwa komjovo, iIsikulufu esisodwaingxenye yamandla eyinhloko yawo wonke umugqa wokukhiqiza. Idizayinwe kahle futhi yakhiwe ngokunemba, ayinqumi kuphela ukuzinza kwezinto ezidluliswayo kanye nekhwalithi yokwenza ipulasitiki, kodwa futhi ithinta ngokuqondile ukunemba kobukhulu bemikhiqizo eqediwe nokuqhubeka kokukhiqiza. Ibhekene nezinto eziyinkimbinkimbi eziqukethe i-glass fibre, i-calcium carbonate, izigcwalisi zamaminerali, nezithasiselo ezibolayo, igcina ukumelana nokugqokwa okuhle nokunemba okuzinzile kokucubungula kwale ngxenye ebalulekile ngaphansi komthwalo ophezulu wesikhathi eside, ukungqubuzana okuphezulu nezinga lokushisa eliphezulu sekugxilwe kubuchwepheshe kubaphathi bemishini nonjiniyela bezinqubo.

I-Wear and Corrosion: Izimbangela Eziyinhloko Ngokusekelwe Kudatha Yokukhiqiza

Izinto eziholela ekuhlulekeni kwesikulufu ngaphambi kwesikhathi zihlobene ngokuqondile nezici zezinto ezicutshunguliwe. Izinto ezihlukene zikhiqiza izindlela zokulimala ezahlukene ku-aIsikulufa Esisodwa,edinga izixazululo zokuvikela eziqondisiwe. Ithebula elingezansi lifingqa izinhlobo ezintathu ezijwayelekile zokulimala kwezinto kanye nemiphumela yazo:

Emkhiqizweni wangempela, ukubola kwe-abrasive kanye nokugqwala kwamakhemikhali kuvame ukushintshanisa, okuqhubekisela phambili ukusheshisa ukuwohloka kwesikulufu. Ngakho-ke, uhlelo lokuvikela oluphelele kufanele lwakhiwe ngezici ezintathu: impahla, ukwelashwa kokushisa, nobunjiniyela bomhlaba.

Izindlela Zobuchwepheshe Ezibalulekile Zokuthuthukisa Ukumelana Nokunemba Kwe-Wear

Izinqubo Eziyinhloko: Ukuvikelwa Okuhlelekile Kusuka Ekuphathweni Kwezinto Eziyisisekelo kuye Ekuhlanganisweni Okuqinile

Ukuze kuzuzwe kokubili ukumelana nokugqokwa okuphezulu nokunemba okuphezulu, abakhiqizi abangochwepheshe ngokuvamile basebenzisa uhlelo lwenqubo olulandela izinyathelo ezilandelayo:

• Isisekelo sokucisha kanye nokushisa-Sebenzisa insimbi engu-38CrMoAlA alloy, yenza ukucisha kanye nezinga lokushisa eliphezulu ukuze uthole ukwakheka kwe-sorbite epholile, ukhiphe ingcindezi ekhangayo futhi unikeze ukuqina okuhle komgogodla.
• Ukunemba kokugaya– Sebenzisa amasilinda anembe kakhulu kanye nezigaya zentambo ze-CNC ukuze uqinisekise ukunemba kwejometri yephrofayela yendiza. Ubuqotho, ukubekezelela iphimbo, kanye nokuqina kwendawo aIsikulufa Esisodwazilawulwa ziye ezingeni le-micron, zinciphisa ukugeleza kwe-melt back kanye nokungqubuzana kwendawo.
• I-surface nitriding– Faka igesi noma i-ion nitriding ukuze wenze ungqimba olumhlophe olungu-0.3–0.6 mm endaweni eyisikulufu, uzuze ubulukhuni obungaphezulu be-HV900–1100, uthuthukise kakhulu ukumelana nokuguga kuyilapho ugcina ukuqina okuyinhloko.
• I-Electroplating noma i-electroless Plating- Ezintweni ezigqwala kakhulu (isb., i-PVC, i-fluoroplastics), engeza ungqimba lwe-nickel eqinile ye-chromium noma i-electroless nickel phezu kongqimba olune-nitrided ukuze uvale izimbotshana ezincane futhi uthuthukise ukumelana nokugqwala, kuyilapho wehlisa ukunamathela kokuncibilika.
• I-Dual-alloy spray welding (i-PTA noma i-laser cladding)- Ngezinto ezilimaza kakhulu ezifana ne-glass fiber, i-calcium carbonate, noma izinto ezigaywe kabusha, sebenzisa i-nickel-based noma i-cobalt-based alloy kumathiphu endiza, uzuze ubulukhuni ngaphezu kwe-HRC60. Lesi sakhiwo esiyinhlanganisela sivumela isikulufu ukuthi sigcine umthamo wokwenza ipulasitiki ozinzile kanye nokucaciswa okunembile ngaphansi kwe-extrusion yesivinini esiphezulu kanye nezindawo ezibolayo.

I-Precision Machining kanye Nokumatanisa Inqubo: Ukuqinisekisa I-Plasticizing Efanayo kanye Nokungaguquguquki Komkhiqizo

Ukunemba okuphezulu akukhona nje kuphela ukubekezelela kobukhulu besikulufu, kodwa futhi mayelana nokulawula ukucaciswa phakathi kobubanzi bendiza eyisikulufa nodonga lwangaphakathi lombhobho. Okuhlangenwe nakho kubonisa ukuthi ukulawula imvume phakathi kwe-aIsikulufa Esisodwa futhi umgqomo ongaphakathi kuka-0.10-0.20 mm (kuye ngokuthi ububanzi) unciphisa kakhulu ukuvuza kokuncibilika futhi ukwandise ukuphuma okuthile. Ngaphezu kwalokho, amapharamitha wejiyomethri athuthukisiwe (isilinganiso sokuminyanisa, isilinganiso se-L/D) esimataniswa nezihlahla zokuphakelayo zomgqomo ogobile zingafinyelela ukufakwa kwepulasitiki okuphezulu kwe-shear ngesivinini esiphansi sesikulufu, kunciphise izinga lokushisa lokuncibilika cishe ngo-10°C, ngaleyo ndlela kuthuthukiswe ikhwalithi yendawo yomkhiqizo nokuzinza kobukhulu.

Izixazululo Eziphelele Zezimo Zokusebenza Ezinzima

Okwezinto ezikhethekile ezifana ne-wood-plastic composite (WPC), amapulasitiki obunjiniyela agcwele kakhulu, nezinto ezigaywe kabusha, abakhiqizi abaholayo basukile ekucubunguleni ingxenye elula baya kumasevisi obuchwepheshe ahlanganisiwe ahlanganisa “ukukhethwa kokubalulekile - ukwakheka kwenqubo - ukwelashwa kwangemuva".

Isibonelo, kunayiloni eqinisiwe equkethe ifayibha yengilazi engaphezu kuka-30%, isikulufu singaklanywa sibe nokuphakama okuguquguqukayo nokujula kwesiteshi okuguquguqukayo, ngoshintsho oluyindilinga empandeni yendiza ukuze kuncishiswe ukugxiliswa kwengcindezi. Kuhlanganiswe ne-dual-alloy spray welding kanye nokupholishwa kwesibuko (ubukhulu obuphezulu obungu-Ra ≤ 0.05 μm), lokhu kunciphisa ubungozi bediphozithi ye-carbon futhi kusiza ukuhlanzwa.

Isiphetho: Inani Lesikhathi Eside Lokutshala Imali Esikulungeni Sokusebenza Okuphezulu

Kafushane, aIsikulufa Esisodwaekhiqizwe ngomklamo onembile kanye nokwelashwa okuningi okuvikelayo akugcini nje ngokunweba kakhulu impilo yayo yesevisi, kodwa futhi kuthuthukisa ukusebenza kahle kwamandla okukhipha kanye nokubumba umjovo, kunciphisa imvamisa yokulungisa, futhi iqinisekisa ukungaguquguquki kwekhwalithi yomkhiqizo. Lapho izinkampani zokucubungula ipulasitiki zikhetha umkhiqizi othandaI-I-Zhoushan Nanhaiya Plastic Machinery Co., Ltd.- enochungechunge lwenqubo oluphelele, okokusebenza kwemishini okunembayo, kanye nolwazi olubanzi lwemboni - bathola isiqiniseko sobuchwepheshe sokuma okukodwa kusuka kuntokozo yesikulufu, ukwelashwa kokushisa kuya ekuhlanganisweni kwendawo, babeka isisekelo esiqinile sokukhiqiza okuzinzile kwesikhathi eside.
