Matanidza dhiramu kune yako zvinhu, kwete kune mutengo tag.
Sarudza iyo isiriyo screw barrel uye chimwe chezvinhu zviviri chinoitika. Ungave iwe unobhadharira alloy layer maitiro ako haambomanikidzira, kana iwe unochengetedza mazana mashoma emadhora kumusoro uye woona yakachipa dhiramu kupera mumwedzi gumi nesere - uchitora yako yauchaburitsa uye yako kunyungudika kunaka pasi nayo. Takavaka marudzi ese ari maviri kweanopfuura makore makumi maviri, uye mubvunzo watinonzwa zvakanyanya kubva kune vatengi ndiwo wauri kubvunza izvozvi:bimetallic vs nitrided screw barrel, nzira yekuenda nayo?
Iri gwara rinofamba nemusiyano chaiwo wesimbi pakati pezviviri, mutengo wemasvomhu unonyanya kukosha (hiti: hausi iwo mutengo wekunamira), uye nzira iri nyore yekusarudza kuti ndeipi.screw barrelinokodzera muchina wako, zvinhu zvako, uye bhajeti yako.
Chii chinonzi Nitrided Screw Barrel?
A nitrided screw barrelinotanga sechidimbu chesimbi - nguva dzose38CrMoAlAmuchitoro chedu - uye inoomeswa pamusoro-soro muchoto chenitriding. Iyo nzira inoparadzira nitrogen muganda resimbi pane inodzorwa tembiricha kwemaawa akawanda. Hapana chinhu chechipiri chinowedzerwa. Simbi inongokura goko rekunze rakaomarara.
Chaunoguma nacho kuoma kwepamusoro kwakatenderedza HV 950–1000 uye nitrided layer inosvika 0.5 kusvika 0.7mm kudzika. Iro ganda rakatetepa, rakaomarara rinobvisa abrasion kubva kune akajairwa mapolymer uye rinoita kuti chiboro chirambe chakadzikama, kumhanya mushure mekumhanya. Nitrided barrels yanga iri iyo indasitiri yekusarudzika kwemakumi emakore, uye nechikonzero chakanaka: zvehupfumi, zvinofanotaurwa, uye zvinopfuura zvakaringana kune asiri-abrasive, asina-kuora resins akadai sePP, PE, uye ABS.
Kubata kwakadzika. Kamwe iyo sub-millimeter layer yapera - uye mukuita abrasive ichaita - iyo yakapfava simbi yepasi inoburitswa pachena, uye kupfeka kunotanga kutiza kubva kwauri.
Chii chinonzi Bimetallic Screw Barrel?
A bimetallic screw barrelinotora nzira yakapesana nedambudziko rakadzika. Panzvimbo yekuomesa simbi imwe chete, inosanganisa alloy yepamusoro-soro panheyo yakaoma. Nheyo yesimbi - simbi yekugadzira - inotakura mutoro uye inochengeta dhiramu yakaoma. Iyo yemukati yekushanda pamusoro ndeye yakaparadzana alloy layer, kazhinji nickel-based kana tungsten-carbide-based, yakasungirirwa kune hwaro kuburikidza necentrifugal casting. Idzo simbi mbiri dzinokiyiwa kuita chidimbu chimwe chete.
Hezvino izvo zvinoita mutsauko: iyo yekudzivirira layer inomhanya 2.0 kusvika 3.0mm kudzika, pakuoma kweHRC 60-65. Isa iyo padivi peganda rehafu-millimeter pane nitrided barrel uye iyo pfungwa yese inouya mukutarisa. Kupfeka kuramba kunopararira munzvimbo yakakora zvakanyanya, saka dhiramu rinobata jiometri yaro kureba kana richirwisa abrasion kana ngura. Girazi faibha, mineral fillers, halogen-bearing compounds - zvinhu zvinotsenga kuburikidza nenitrided surface - ndiko chaiko uko bimetallic layer inowana kuchengetwa kwayo.
Haasi ese bimetallic layers akafanana, kana. Iyo nickel-based alloy inorerekera kune corrosion kuramba - sarudzo chaiyo yePVC uye zvinodzosa moto. Iyo tungsten-carbide-rich layer inotsamira yakananga mbishi abrasion kuramba, zvinova izvo zvinoda girazi-fiber uye yakakwirira-mineral makomisheni. Iron-based alloys inogara pakati sepakati-inoziva mari yepakati. Kufananidza alloy kune chaiyo muvengi - ngura kana abrasion - zvine basa zvakada kuita sekusarudza bimetallic pakutanga.
Bimetallic vs Nitrided Screw Barrel: Key Differences
Nzira iri nyore yekuona gap iri padivi nepadivi. Tafura inovaisa pamusoro pezvinhu zvinofambisa sarudzo yekutenga.
| Factor | Nitrided Screw Barrel | Bimetallic Screw Barrel |
|---|---|---|
| Kuvaka | Single simbi (38CrMoAlA), pamusoro-nitrided | Base simbi + fused alloy yemukati layer |
| Kuoma kwechiso | HV 950–1000 | HRC 60–65 |
| Yakaomeswa layer kudzika | 0.5–0.7mm | 2.0–3.0mm |
| Pfeka kuramba | Yakanaka kune isina-abrasive resins | 2-5 × kureba mubasa reabrasive |
| Corrosion resistance | Limited | Yakanakisa (nickel-based alloys) |
| Zvakanakisa-zvakakodzera zvinhu | PP, PE, ABS, akajairwa makomisheni | PVC, girazi faibha, inodzoreredza murazvo, yakadzokororwa, yakakwira-yekuzadza |
| Mari yekutanga | Lower | Higher |
| Mari yese yekuva muridzi | Wepamusoro mubasa rinoda | Kuderera mubasa rinoda |
Nhamba yakawanda processors inogadziriswa pahupenyu hwesevhisi, uye ndizvozvo. Mumamiriro ezvinhu akafanana, abimetallic screw barrelkazhinji inomhanya zvakapetwa kaviri kana katatu pane imwe nitrided. Sunda mumashandisirwo ekuranga - yakakwira-filler PVC, girazi-yakasimbiswa makomisheni - uye gaka rinowedzera richiri. Pane kona yekuora zvakare: kana iwe uchigadzira PVC kana murazvo-anodzoreredza resin, zvinhu zvinoburitsa makomisheni ayo anorwisa makemikari nzvimbo ine nitrided. Iyo nickel-based bimetallic layer haina hanya.
Nguva Yekusarudza Nitrided Screw Barrel
A nitrided screw barrelndiko kufona kwakakodzera kakawanda kupfuura izvo mutengesi wemidziyo achabvuma. Mhanyai yakachena, isina kuzara thermoplastics - mhandara PP, PE, PS, ABS - isina girazi fiber, isina mineral filler, isina corrosive additives, uye iyo nhete ye nitrided layer inokupa makore ebasa rakagadzikana nemutengo unooneka wakaderera.
Izvo zvakare zvine musoro kana bhajeti rakasimba, kana muchina uchimira uye uchitanga kwete kutenderedza wachi, kana paunenge uchimisa mutsara une chigadzirwa musanganiswa unogona kuchinja dhiramu risati rapera. Zvemwerojekiseni kuumba sikurukumhanya commodity resin, kubhadhara yakawedzera kune bimetallic layer iwe haungambo shushikana ingori pamusoro-engineering. Usazviita.
Nguva Yekusarudza Bimetallic Screw Barrel
Nguva iyo abrasion kana ngura inopinda mumufananidzo, abimetallic screw barrelinowana mutengo wayo wepamusoro. Svikira pazviri kana ukagadzira chero cheizvi: girazi-fiber-yakasimbiswa makomisheni, calcium-carbonate kana talc-yakazadzwa maumbirwo,yakaoma PVC, resin-retardant resin, kana mapurasitiki akashandiswa zvakare anotakura grit nezvinosvibisa.
Ndiko zvakare kungwara kutenga mitsara inobuditsa yakakwira inoramba ichimhanya, uko kumira kusina kurongeka kwekuchinjanisa dhiramu rakasakara kunodhura zvakanyanya kupfuura dhiramu pacharo. Takaona yakakwira-calcium PVC extrusion - inenge yakaoma padhiramu sezvainosvika - kwainoenda kune yakakodzera alloy layer yakawedzera hupenyu hwesevhisi nepamusoro pe30% pakatarisana neiyo nitrided setup, uku ichidzikamisa kunyungudika uye kucheka zvimedu. Kana iyo application ichinyatsoda, iyo bimetallic layer inomira kuve yakasarudzika. Ndizvo zvinoita kuti mutsara urambe uri muhumwe.
Mutengo Kuenzanisa: Yekutanga Mutengo vs Yese Mutengo weUridzi
Iwo masikirwo ekuenzanisa mitengo yekunamira ndizvo chaizvo zvinotungamira kune yakaipa screw barrel sarudzo. Nitrided barrel inokunda pazuva rekutanga. Abimetallic screw barrelkazhinji anokunda pamusoro pehupenyu hwemuchina - asi mukushandisa kwakakodzera.
Saka mhanya imwe nhamba: mutengo wakazara wemuridzi. Bhareri ine nitrided mune abrasive process ingangoda kutsiviwa mumwedzi gumi nemiviri kusvika gumi nemisere, uye imwe neimwe inotsiviwa inodhonza ne teardown labor, yakarasika kugadzirwa, uye marara ekutanga pamusoro pemutengo wechikamu. Bimetallic barrel mune imwecheteyo maitiro inogona kumhanya kakawanda, ichiparadzira mutengo wayo wepamusoro wepamusoro mumaawa akawanda ekugadzira. Mutengo wekutanga wepamusoro, mutengo wakaderera wehupenyu.
Zvino flip it. Isa bimetallic barrel pamutsara wePE wakachena uye haimbowani mukana wekuzvibhadharira wega - iyo nitrided barrel inokunda pamutengo uye mutengo wehupenyu hwese, nekuti hapana mukuita ikoko kunosimbisa alloy. Same logic, mhinduro yakapesana. Zvinyorwa zvinosarudza.

Bvunza mibvunzo mitatu.
Chekutanga - zvinhu zvako zvinokusha here kana kuti zvinoora?Girazi faibha, mineral fillers, PVC, flame retardants, recycled feedstock: ese anonongedzera bimetallic. Yakachena commodity resin inonongedzera kune nitrided.
Chechipiri - mutsara unomhanya zvakadii?Kuenderera mberi, kuburitsa kwepamusoro, kutenderera-nguva-yachi kugadzirwa kunopa mibairo yehupenyu hurefu hwebimetallic screw barrel. Inopindirana kana yakaderera-vhoriyamu inomhanya inofarira mutengo wakaderera we nitriding.
Chechitatu - nguva yekuzorora inokutadzirei?Kana isina kurongeka dhiramu shanduko inoreva hurongwa hwakamira uye kupotsa kuendesa, iyo durability premium inshuwarisi yakachipa. Kana iwe uchigona kuronga shanduko, masvomhu anodzokera kumashure akananga kune nitrided.
Pindura avo vatatu vakatendeseka uye sarudzo inowanzova pachena. Kana zvisina kudaro, taura nemutengesi anovaka zvese uye anogona kuitevedzera zvichienderana nekomboni yako chaiyo - kwete uyo anokukanganisa kune chikamu chemutengo nekuti chinotakura muganho mukuru.
