Nyob rau hauv niaj hnub yas molding teb, lub thoob thiab ntsia hlau, raws li cov tub ntxhais plasticizing units ntawm ib tug txhaj tshuaj molding tshuab, txiav txim siab cov cuab yeej ua adaptability, zog efficiency, thiab cov khoom zoo los ntawm lawv cov yam ntxwv kev. Los ntawm cov qauv tsim qauv thiab cov khoom siv sib xyaw ua ke, lawv ua tiav cov melting zoo, kev sib xyaw ua ke, thiab kev ntsuas meej ntawm ntau yam khoom siv yas, ua tau raws li kev xav tau ntau yam kev lag luam.
Cov yam ntxwv ntawm lub thoob yog feem ntau xav txog nyob rau hauv nws refined thermal tswj peev xwm. Nws ntiav cov cua sov thiab cua txias segmented, tsim kom muaj kev tswj tau qhov kub thiab txias gradient raws axial kev taw qhia. Qhov no ua kom muaj kev ruaj ntseg ntawm cov khoom siv raw cov txheej txheem maj mam softening los ntawm cov khoom mus rau cov khoom, thaum tiv thaiv cov overheating hauv zos uas yuav ua rau cov khoom degradation. Sab hauv phab ntsa feem ntau siv bimetallic composite los yog txheej txheej txheej txheem los txhim khu kev hnav thiab corrosion kuj, yoog mus rau ntev - lub sij hawm ua cov ntaub ntawv abrasive heev los yog corrosive. Lub thoob lub cev feem ntau yog ua los ntawm siab- lub zog alloy steel los ntawm forging los yog centrifugal casting, muaj cov rigidity zoo heev los tiv thaiv sab hauv siab thiab ua kom cov duab ruaj khov nyob rau hauv siab - kev khiav hauj lwm ceev thiab nquag hloov pauv.
Cov ntsia hlau qhov zoo tshaj plaws yog tsom rau hauv kev sib xyaw ua ke ntawm ntau yam -functional segment structure thiab deg strengthening processes. Cov ntsia hlau raug muab faib ua ntu pub, ntu compression, thiab seem homogenization raws li cov khoom ntws. Cov ntsia hlau channel qhov tob, helix lub kaum sab xis, thiab qhov ntev piv tau raug xam kom ua tiav cov txiaj ntsig zoo ntawm kev cog lus, shear plasticization, thiab ruaj khov extrusion. Rau cov khoom siv raw nrog cov viscosities sib txawv, kub rhiab heev, los yog muab tub lim sib piv, qhov sib txawv ntawm qhov sib txawv, qhov sib txawv ntawm qhov sib txawv, lossis cov ntaub ntawv sib txuas ntsia hlau tuaj yeem hloov kho tau los txhim kho plasticization efficiency thiab sib xyaw ua ke. Nyob rau hauv cov nqe lus ntawm kev kho deg, nitriding, ion carburizing, bimetallic sintering, thiab laser cladding technologies tau dav siv, ho txhim kho hardness thiab hnav tsis kam ntawm cov khoom tseem ceeb thiab ncua kev pab cuam lub neej.
Lub thoob thiab ntsia hlau haum hais txog qhov siab precision thiab dynamic tshuav nyiaj li cas. Qhov sib txawv ntawm lawv yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias tsis muaj kev sib txhuam thiab kev sib khi zoo, tiv thaiv yaj rov qab thiab tsis sib xws plasticization. Kev tsim qauv kev sib txuas ntawm lub tshuab tsav thiab cov ntsia hlau ua kom ntseeg tau tias kev sib kis tau zoo thiab coaxiality siab, txo qhov hnav tsis zoo tshwm sim los ntawm kev tawm - chaw thau khoom. Tag nrho cov yam ntxwv kev yog tus yam ntxwv los ntawm npaum thiab controllable synergistic hloov dua siab tshiab ntawm thermal thiab mechanical zog, tuav ruaj khov yaj zoo thiab tso zis nyob rau hauv ib tug ntau yam ntawm cov txheej txheem tsis.
Raws li cov txheej txheem plastics txav mus rau qhov siab dua, muaj peev xwm ntau dua, thiab ib puag ncig tus phooj ywg, lub taub hau ntsia hlau tau hloov zuj zus mus rau lub neej ntev, kev hloov pauv ntau dua, thiab kev siv hluav taws xob qis dua. Cov yam ntxwv thev naus laus zis no tsis yog tsuas yog qhov tshwm sim ntawm cov khoom siv kho kom zoo xwb tab sis kuj yog ib qho tseem ceeb ntawm kev sib sib zog nqus ntawm cov ntaub ntawv kev tshawb fawb, thermal technology, thiab cov txheej txheem tsim khoom, muab kev txhawb nqa zoo rau siab - zoo thiab kev loj hlob zoo hauv kev txhaj tshuaj molding.
