Vim yog qhov tshwj xeeb ntawm nws cov txheej txheem tsim khoom, kub-extruded aluminium profiles yuav pom cov nram qab no defects thaum lub sij hawm kub extrusion txheej txheem, tshwm sim ncaj qha los yog tsis ncaj qha los ntawm pwm polishing zoo los yog txheej txheem txheej txheem: ntxhib ntxhib los mos, xim sib cais, tsaus bands, ci bands, khawb, ribbing, thiab tsis zoo smoothness.
Ua rau Rough Surface Defects nyob rau hauv Extruded Aluminium Profiles: Nyob rau hauv lub extrusion zus tau tej cov txhuas profiles, ib qho tsis xws luag yog intuitive heev, xws li khoov, twisting, deformation, thiab slag inclusion.
Aluminium profiles uas tawm ntawm extrusion ntau lawm kab raug xa mus rau cov khoom siv hauv paus, billet, lossis cov khoom siv raw.
Kev ntsuam xyuas ua ntej ntawm qhov zoo ntawm qhov chaw yog feem ntau ua tom qab 2-3 daim yog extruded tom qab tuag teeb. Cov qauv pib raug coj los ua qhov kev txiav txim ua ntej seb qhov zoo ntawm qhov chaw puas tau. Thaum qhov chaw pom tau tias ua tau, lwm yam kev tshuaj xyuas yog nqa tawm.
5 Txoj hauv kev los soj ntsuam ceev nrooj qhov tsis zoo ntawm Aluminium Extrusion Billets
1. Tactile kov: Siv koj txhais tes los kov qhov chaw ntawm lub substrate, los yog khawb nrog koj cov ntiv tes kom hnov qhov grooves lossis tsa qhov chaw, thiab txiav txim siab seb puas muaj qhov pom tseeb tactile. Muaj feem xyuam rau kev txiav txim ntau yam kev kho deg.
2. Cwj mem khawb: Thaum lub sij hawm extrusion ntawm aluminium profiles, siv ib tug cwj mem los kos rau saum npoo ntawm aluminium profile. Los ntawm kev xav thiab saib xyuas qhov txuas ntxiv ntawm cov cwj mem kos, txiav txim siab seb puas muaj cov qauv ntxhib lossis grooves. Haum rau kev txiav txim siab ntawm cov khoom siv anodized.
3. Kev tshuaj ntsuam xyuas xim: Rau thawj qhov kev kuaj xyuas, siv cov tshuaj tsis siv neeg los pleev xim rau saum npoo ntawm substrate, simulating painting teebmeem. Tom qab 1-2 feeb, thaum lub npoo qhuav, saib thiab txiav txim seb puas muaj khawb, zawj, tsa qhov chaw, lossis lwm yam tsis xws luag. Haum rau kev txiav txim siab pleev xim rau qhov chaw.
4. Alkali Washing Test: Thaum lub sijhawm kuaj thawj zaug, coj tus qauv 300mm los ntawm tus pas nrig thib 3, thiab muab tso rau hauv lub tank pwm rau 30-40 vib nas this. (Faj seeb: xav txog cov tshuaj alkali concentration thiab tank kub; yog hais tias lub concentration los yog tank kub yog tsawg heev, tsim nyog ncua lub sij hawm soaking, feem ntau tsis pub tshaj 60 vib nas this.) Tom qab alkali ntxuav, qhov saum npoo ntawm substrate tuaj yeem kuaj xyuas qhov tsis xws luag xws li xim sib cais, sib tw, lossis pwm weld kab. Qhov no yog tsim rau cov khoom siv oxide nrog cov kev xav tau siab saum npoo.
5. Kev Sib Tsoo Ntog: Thaum lub sijhawm kuaj thawj zaug, coj cov qauv 300mm thiab siv cov ntaub dawb huv los zom cov substrate nto transversely. Tom qab sib tsoo, nws yooj yim dua los saib xyuas qhov tsis xws luag ntawm lub substrate nto. Qhov no yog siv los txheeb xyuas qhov tsis xws luag xws li khawb zoo, (tsis yooj yim khaws nrog tus ntiv tes) concave bulges, convex bulges, thiab defects uas nyuaj rau txiav txim siv plaub txoj kev saum toj no. Nws muaj feem xyuam rau kev soj ntsuam saum npoo ntawm cov coatings, cov ntaub ntawv anodized, thiab cov ntaub ntawv fluorocarbon.
Thawj kauj ruam yog kev tshuaj xyuas sai los txiav txim siab seb qhov chaw zoo puas tau txais. Txawm hais tias thawj daim yog tsim nyog, cov xwm txheej txawv txav tseem tuaj yeem tshwm sim thaum lub sijhawm extrusion txheej txheem. Yog li ntawd, nyob rau hauv qhov tseeb ntau lawm, nws yog tsim nyog los tsim ib tug tsim nyog soj ntsuam zaus raws li qhov hnyav ntawm lub hauv paus khoom tsis xws luag, hom kev kho deg, thiab nyob rau hauv ua ke nrog nrog rau cov kev txiav txim thiab cov neeg siv khoom zoo, raws li qhov yuav tsum tau ntawm lub lag luam cov lus qhia. Cov txheej txheem tsim nyog yuav tsum raug xaiv rau kev ntsuam xyuas, txiav txim siab raws sijhawm thiab raug, nrog lub hauv paus ntsiab lus ntawm kev zam kev txiav txim tsis raug lossis tsis raug txiav txim.
