1. Extruder Screw thiab chim: Qhov no yog qhov chaw tseem ceeb rau corrosion kuj. Cov khoom siv hauv paus rau cov ntsia hlau thiab cov thoob yog feem ntau alloy hlau zoo li 38CrMoAlA, tab sis qhov tseeb corrosion tiv thaiv los ntawm cov txheej txheem kho saum npoo. Ib txoj hauv kev yog nyuaj chrome plating, uas muab cov txheej txheem tiv thaiv kom zoo cais cov roj corrosive. Cov txheej txheem qib siab ntxiv muaj xws li bimetallic casting lossis nitriding, ua kom muaj siab -hardness corrosion- resistant txheej rau saum npoo. Yog tias cov cuab yeej siv no tau ua tiav PVC ua ntej, ua tib zoo tshuaj xyuas cov ntsia hlau flutes thiab lub thoob sab hauv phab ntsa kom pom qhov hnyav, pom, lossis cov cim ntawm chrome plating tev. Thaum cov txheej txheem tiv thaiv raug cuam tshuam, lub hauv paus hlau corrodes sai, ua rau txo qis extrusion tso zis thiab muaj peev xwm dub scorch cov khoom.
2. Pwm (Sprue thiab Tuag): Pwm khiav tuaj rau hauv kev sib cuag nrog siab - kub yaj, xav tau tshwj xeeb corrosion kuj. Cov hlau siv rau pwm fabrication yuav tsum muaj qhov zoo heev corrosion kuj thiab polishability, nrog rau cov khoom siv xws li H13, P20, lossis siab dua - qib stainless hlau. Cov neeg khiav dej num sab hauv yuav tsum tau tsim nrog kev sib tw, tuag- lub kaum -dawb geometries thiab daim iav- polished nto los tiv thaiv lub sij hawm tsub zuj zuj ntawm corrosive gases ntawm stagnation cov ntsiab lus, uas yuav ua rau pitting corrosion. Thaum kuaj xyuas cov pwm siv, nws yog ib qho tseem ceeb uas yuav tau qhib pwm thiab tshuaj xyuas seb qhov chaw khiav haujlwm puas yog daim iav- du, tsis muaj qhov tsaus nti lossis qhov pits tshwm sim los ntawm corrosion. Qhov no ncaj qha txiav txim siab pwm qhov kev pab cuam lub neej thiab qhov zoo ntawm cov khoom tiav.
3. Tsim Moulds thiab Cooling Water Tanks: Txawm hais tias qhov no yog qhov chaw txias, PVC volatiles yuav condense hauv dej, tsim cov dej tsis muaj zog. Kev tsim pwm feem ntau yog ua los ntawm aluminium alloy lossis stainless hlau. Aluminium alloy pwm yog lub teeb yuag thiab muaj cov thermal conductivity zoo, tab sis lawv qhov chaw feem ntau yuav tsum muaj zog anodizing los tsim cov corrosion- resistant txheej. Yog tias txheej txheej anodized puas lawm, aluminium alloy yuav corrode sai hauv cov dej acidic, tsim cov pob dawb thiab hmoov. Stainless hlau tso tsheb hlau luam thiab pwm muab kev tiv thaiv corrosion zoo dua tab sis tuaj ntawm tus nqi siab dua. Kev tshuaj xyuas lub tshuab nqus tsev thiab cov dej nkag sib txuas ntawm cov pwm molding rau xeb lossis xau muab ib txoj hauv kev yooj yim los ntsuas qhov kev tiv thaiv corrosion ntawm cov khoom no.
4. Traction Machine Tracks thiab Cutting Machine Blades: Txawm hais tias cov khoom no tsis ncaj qha mus rau siab - cov khoom kub molten, lawv tuaj yeem cuam tshuam nrog cov khoom corrosive volatilizing lossis condensing los ntawm cov yeeb nkab nto. Yog hais tias lub chrome plating ntawm lub tshuab traction lub siab lub tog raj kheej lub tog raj kheej thiab cov lus qhia rods puas, xeb thiab jamming tuaj yeem yooj yim tshwm sim. Cov hniav saws los yog planetary txiav hniav ntawm lub cutter feem ntau yog ua los ntawm high-ceev steel los yog feature carbide-tipped inserts. Lawv yuav tsum muaj kev tiv thaiv corrosion txaus los tiv thaiv xeb uas dulls lub ntug txiav thiab cuam tshuam kev txiav zoo.
