I-Mutant Single Screw

Lesi sikulufu esisodwa se-mutant senziwe ngensimbi engu-38CrMoAla. Izinto ezingavuthiwe zibalulekile ekusebenzeni ngezikulufu, futhi sikhetha insimbi enamandla amakhulu nengagugi kubakhiqizi bensimbi abadumile baseShayina abahlangabezana nezindinganiso zikazwelonke (GB/T 3077).

I-Nanhaiya's mutant single screw extruder igcina ukuphakama okungaguquki, futhi ukujula kwesiteshi sayo kuhlala kungashintshile esigabeni sokuphakelayo nese-homogenizing. Kodwa-ke, ukujula kwesiteshi kuvele kunciphe kakhulu esigabeni sokuncibilika. Lesi sakhiwo sinika amandla isikulufu ukuthi sisebenzise amandla aqinile okucindezelayo ezintweni ezisesigabeni sokuncibilika. Njengoba izinto zingena esigabeni sokucindezela kusukela esigabeni sokudla, ukuthuthumela okungazelelwe kokujula kwesiteshi kubangela ukucindezelwa okukhulu nokugunda, okuholela ekwandeni okusheshayo kwamandla kanye nezinga lokushisa phakathi nesikhathi esifushane, okuholela epulasitiki ngokushesha.

Isigaba sokuminyanisa i-mutant single screw extruder sivumela okokusebenza ukuthi kuguquke ukusuka kokuqinile kuye koketshezi ngesikhathi esifushane, kuthuthukisa kakhulu ukusebenza kahle kwe-plasticization futhi kuyenze ifanelekele ukukhiqizwa kwenani elikhulu. Ukushintsha okungazelelwe ekujuleni kwesiteshi kubeka okubalulekile amandla okugunda okuqinile, okwenza kube ngcono ukwenziwa kwepulasitiki nokuxubaniswa kwamapulasitiki athile ane-viscosity ephansi, ageleza kakhulu.

Imiphongolo yesikulufu esisodwa esiguquguqukayo ye-Nanhaiya seyenziwe kwi-R&D eminingi kanye nentuthuko futhi manje isihlanganiswe emigqeni yokukhiqiza yabakhiqizi abahlukahlukene, kuzuzwe ukusebenza kwesimanjemanje. Sinikeza iwaranti yeminyaka engu-1-2, kuye ngesilinganiso esithile sokwengezwa kwempahla. Imiphongolo ye-Nanhaiya ingena kunqubo ye-nitriding, enogqinsi oluwu-0.8~2m olujiyile lwe-nickel-tungsten alloy eshiselwe ezindaweni ezithandwa kakhulu. Lokhu kwandisa ubulukhuni bobuso bomgqomo yi-HRC55~62, kukhulisa ukumelana nokugqoka izikhathi ezingu-2-3.

Ipharamitha Yezobuchwepheshe

Isici Futhi Isicelo

I-Nanhaiya's mutant single screw extruder zifaka isigaba esifushane sokuminyanisa, ngokuvamile esibalela cishe u-5% -15% wesamba sobude bezikulufu, futhi kwezinye izimo, izikhathi eziphindwe izikhathi ezingu-1-2 kunobubanzi besikulufa (D). Lesi sigaba sokucindezela esifushane sivumela izinto ukuthi ziguquke zisuka kokuqinile ziye oketshezini ngesikhathi esifushane, zithuthukisa kakhulu ukusebenza kahle kwe-plasticizing. Ngesikhathi senqubo yokubumba umjovo, ipulasitiki eningi ingafakwa ngokushesha futhi ilethwe emgodini wokubumba, ihlangabezane nezidingo zokukhiqiza. Lokhu kuyenza ifaneleke ikakhulukazi izinhlelo zokusebenza ezidinga ukusebenza kahle kwe-plasticizing.

I-Mutant single screw extruder ingasetshenziswa ukukhiqiza amaphrofayili epulasitiki ahlukahlukene, njengamaphrofayili eminyango namafasitela namapayipi. Kumapulasitiki e-crystalline afana ne-polyvinyl chloride (PVC) kanye ne-polyamide (PA), ama-extruder we-mutation-screw single angancibilika ngokushesha futhi enze ipulasitiki into, bese iyikhipha ngokufa ibe yisimo sephrofayela oyifunayo. Ama-extruder we-single-screw wohlobo lokuguqula aphinde abe nohlelo oluthile ekukhishweni kwamafilimu epulasitiki, njenge-PE ne-PP.

Imininingwane Yomkhiqizo

Ukushisa okuthuthukisiwe, ukunemba kwemishini, nezinqubo ze-nitriding ziqinisekisa ukusebenza okuphelele kwezingxenye ezibalulekile.

Izindawo ezisengozini ye-screw kanye nomgqomo ziqiniswa nge-nickel-tungsten alloy layer, ezifinyelela ungqimba oluwugqinsi ongu-0.8-2.0mm futhi kuthuthukisa kakhulu ukumelana nokugqokwa.
