Tom qab kev kho cua sov, cov yeeb nkab stainless hlau puag ncig tsis muaj qhov tsis xws luag, tsis muaj kab nrib pleb, thiab tsis muaj qhov khoov yog muab tso rau ntawm cov khoom siv rau cov menyuam thiab extruded. Qhov no yog ua raws los ntawm kev ua kom ncaj. Lub sijhawm no, cov neeg ua haujlwm soj ntsuam zoo ntawm cov chaw tsim khoom ntawm stainless hlau yeeb nkab yuav kuaj cov khoom siv kho tshuab, tshuaj ntsuam xyuas, tensile test, thiab lwm yam txheej txheem. Tom qab paub tseeb tias nws yog lawm, mus rau sawing thiab txiav. Qhov no yog ua raws li cov txheej txheem sib tsoo thiab polishing.Polished stainless hlau square tubesyuav ua tib zoo ntim los ntawm cov neeg ua haujlwm ntim khoom hauv cov khoom ntim khoom tshiab thiab tuaj yeem xa ncaj qha lossis muab tso rau hauv lub tsev rau khoom.
Dab tsi ntawm stainless hlau square raj yog qis dua?
1. Sab nrauv ntawm cov khoom cuav thiab tsis zoo stainless hlau square raj muaj qhov tsis sib xws tsis sib xws. Vim tias cov tuam ntxhab ntawm cov khoom cuav thiab tsis zoo stainless hlau square tubes nrhiav cov txiaj ntsig, qhov nto flatness feem ntau zoo li qis.
2. Qhov saum npoo ntawm fake thiab inferior stainless hlau square tubes yog nquag caws pliav. Muaj ob qho laj thawj:
(1) Cov khoom siv ntawm cov khoom tsis zoo thiab tsis zoo stainless hlau square kav tsis sib xws thiab muaj ntau yam impurities.
(2) Cov khoom siv qhia ntawm cov tuam txhab cuav thiab cov khoom lag luam tsis zoo yog qhov yooj yim thiab yooj yim rau lo rau hlau. Cov impurities no
3. Qhov saum npoo ntawm cov khoom cuav thiab cov khoom tsis zoo yog qhov ua rau tawg. Yog vim li cas yog qhov khoob yog ua los ntawm adobe, uas muaj ntau qhov pores. Lub adobe yuav raug thermal stress thaum lub sij hawm txias txias, ua rau tawg, thiab cov kab nrib pleb tshwm tom qab dov.
4. Fake stainless hlau square raj yog ib qho yooj yim mus khawb. Yog vim li cas yog qhov fake stainless hlau square tube manufacturers muaj cov khoom siv tsis zoo thiab yog qhov ua rau burrs thiab khawb ntawm cov hlau nto. Sib sib zog nqus khawb txo lub zog ntawm cov hlau.
5. Ntu ntu ntawm cov khoom cuav thiab tsis zoo stainless hlau square tubes yog qhov tsis sib xws. Yog vim li cas thiaj li yuav txuag tau cov ntaub ntawv, cov chaw tsim khoom muaj qhov txo qis ntau dua hauv thawj ob qhov kev hla ntawm cov menyuam tiav. Lub zog ntawm no stainless hlau square raj yog txo qis heev, thiab nws tsis ua raws li cov duab ntawm stainless hlau square raj. Tus qauv loj.
Stainless hlau yeeb nkab manufacturers pom zoo tias thaum twgmuas stainless hlau square kav, koj xaiv lub Hoobkas stainless hlau yeeb nkab nrog zoo heev thiab muaj peev xwm ntau lawm.
