Xaiv ibbimetallic ntsia hlau thoobThaum koj khiav PVC, iav-filled, nplaim-retardant, los yog siv cov khoom siv, qhov twg nws thicker, harder alloy txheej kav ntev li ob mus rau peb zaug. Muab lub thoob rau koj cov khoom, tsis yog rau tus nqi tag.
Xaiv lub hau ntsia hlau tsis raug thiab ib qho ntawm ob yam tshwm sim. Txawm hais tias koj them nyiaj ntau dua rau cov txheej txheem alloy koj cov txheej txheem yeej tsis ntxhov siab, lossis koj txuag tau ob peb puas duas las pem hauv ntej thiab saib lub thawv pheej yig dua nyob rau hauv kaum yim lub hlis - noj koj cov khoom tsim tawm thiab koj cov yaj zoo nrog nws. Peb tau tsim ob hom rau ntau tshaj nees nkaum xyoo, thiab cov lus nug uas peb hnov los ntawm cov neeg yuav khoom feem ntau yog qhov koj tab tom nug tam sim no:bimetallic vs nitrided ntsia hlau chim, txoj kev twg mus?
Phau ntawv qhia no taug kev los ntawm qhov sib txawv ntawm qhov sib txawv ntawm ob qho, tus nqi lej uas tseem ceeb (hint: nws tsis yog tus nqi ntawv nplaum), thiab ib txoj hauv kev yooj yim los txiav txim siab qhov twg.ntsia hlau lub cevhaum koj lub tshuab, koj cov khoom siv, thiab koj cov peev nyiaj.
Dab tsi yog Nitrided Screw Barrel?
A nitrided ntsia hlau chimpib raws li ib daim hlau - yuav luag ib txwm38CrMoAlAnyob rau hauv peb lub khw - thiab tau nto-hardened nyob rau hauv ib tug nitriding rauv. Cov txheej txheem diffuses nitrogen rau hauv cov tawv nqaij steel ntawm qhov ntsuas kub ntawm ntau teev. Tsis muaj cov khoom thib ob ntxiv. Cov hlau tsuas loj hlob ib lub plhaub tawv tawv.
Qhov koj xaus nrog yog qhov nyuaj ntawm qhov chaw nyob ib puag ncig HV 950-1000 thiab ib txheej nitrided roughly 0.5 txog 0.7mm tob. Cov tawv nqaij nyias nyias nyias nyias tawm ntawm kev puas tsuaj los ntawm cov polymers zoo tib yam thiab ua rau lub bore dimensionally ruaj khov, khiav tom qab khiav. Nitrided chim yog qhov kev lag luam ua lag luam rau ntau xyoo lawm, thiab yog vim li cas: kev lag luam, kev kwv yees, thiab ntau tshaj li txaus rau cov khoom siv tsis zoo, tsis muaj corrosive xws li PP, PE, thiab ABS.
Lub catch yog qhov tob. Thaum cov txheej txheej sub-millimeter hnav los ntawm - thiab nyob rau hauv cov txheej txheem abrasive nws yuav - lub softer puag steel hauv qab raug nthuav tawm, thiab hnav pib khiav tawm ntawm koj.
Dab tsi yog Bimetallic Screw Barrel?
A bimetallic ntsia hlau thoobsiv txoj kev rov qab mus rau qhov teeb meem tob. Es tsis txhob hardening ib steel, nws fuses ib tug high-kev ua tau zoo alloy mus rau ib tug tawv puag. Lub hauv paus hlau - ib tug qauv hlau - nqa lub load thiab ua rau lub chim rigid. Qhov chaw ua haujlwm sab hauv yog cov txheej txheem sib cais, feem ntau yog npib tsib xee lossis tungsten-carbide-raws li, sib txuas rau hauv paus los ntawm centrifugal casting. Ob lub hlau metallurgically xauv rau hauv ib thooj.
Nov yog qhov ua rau qhov sib txawv: cov txheej tiv thaiv ntawd khiav 2.0 txog 3.0mm sib sib zog nqus, ntawm hardness ntawm HRC 60-65. Teem ib sab ntawm daim tawv nqaij ib nrab-millimeter ntawm ib lub thoob nitrided thiab tag nrho cov ntsiab lus los ua kom pom tseeb. Kev hnav tsis kam yog kis thoob plaws thaj tsam ntau dua, yog li lub thoob tuav nws cov duab geometry ntev dua thaum nws tawm tsam kev puas tsuaj lossis xeb. Cov iav fiber ntau, pob zeb hauv av, cov khoom siv halogen-cov kabmob - cov khoom uas zom los ntawm nitrided nto - yog raws nraim qhov uas cov txheej bimetallic khwv tau nws khaws cia.
Tsis yog tag nrho cov txheej bimetallic yog tib yam, ib yam nkaus. Lub nickel-raws li alloy leans mus rau corrosion kuj - txoj cai xaiv rau PVC thiab nplaim retardants. Ib txheej tungsten-carbide-nplua nuj leans mus rau raw abrasion tsis kam, uas yog dab tsi iav-fiber thiab high-mineral tebchaw xav tau. Hlau-raws li alloys zaum nyob rau hauv nruab nrab raws li tus nqi-conscious nruab nrab hauv av. Sib piv cov hlau rau cov yeeb ncuab tshwj xeeb - corrosion los yog puas - tseem ceeb yuav luag ntau npaum li kev xaiv bimetallic hauv thawj qhov chaw.
Bimetallic vs Nitrided Screw chim: Qhov txawv qhov tseem ceeb
Qhov yooj yim tshaj plaws kom pom qhov sib txawv yog ib sab. Cov lus qhia lawv txog cov xwm txheej uas ua rau muaj kev txiav txim siab yuav khoom.
