Nyhuv ntawm qhov zoo ntawm extruded profiles ntawm sealing zoo
Tam sim no, tsis muaj kev sim ua kiag li los ua pov thawj txoj kev sib raug zoo ntawm kev ploj, kev laus thiab kev sib sib haum xeeb, tiam sis txoj kev rho tawm yuav cuam tshuam cov kev tsim, qauv thiab cov khoom ntawm oxide zaj duab xis, thiab ua li no cuam tshuam rau qhov zoo ntawm lub sealing.
Nws tau raug pov thawj tias qhov zoo ntawm cov khoom oxidized thiab xim nyob ntawm oxidation txheej txheem nws tus kheej, thiab ntau dua, tseem ceeb, ntawm qhov mob ntawm qhov khoom thaum lub caij extrusion, tshwj xeeb tshaj yog thaum tsis muaj polishing.
Txoj kev ua kom zoo thiab ci ntsa iab ntawm cov khoom yog yooj yim kom tau txais cov yeeb yaj kiab uas muaj suab npe zoo, cov xim tsis muaj teeb meem zoo, qhov ua kom zoo dua qub, tsis muaj lub ntsej muag, zoo li cov yeeb yaj duab oxide, tsuas yog muaj lub cev zoo xwb, tab sis kuj muaj tshuaj lom neeg. Nws pw ib lub hauv paus zoo rau txoj kev ruaj ntseg thiab txhim khu kev sealing.
Qhov nplaim ntawm qhov khoom tsis zoo tsuas yog tsis cuam tshuam rau qhov zoo li, tab sis kuj ua rau cov teeb meem nyob rau hauv cov zaj duab xis oxide, tsis sib luag xim, pluag sealing, thiab tseem khib nyiab uas tsis tuaj yeem ua haujlwm. Txhawm rau kom muaj kev sib khi ntawm oxide zaj duab xis ntawm qhov kub tsis tshua muaj kev kub ntxhov, ib lub tsev zoo nkauj txhim kho cov khoom siv ntawm GB / T5237-93, thiab yuav tsum tau them nyiaj rau hauv cov khoom:
(l) Qhov zoo ntawm qhov khoom tom qab extrusion yog lub hauv paus rau cov khoom tsim muaj cov yeeb yaj kiab oxide zoo. Cov khoom siv oxidized yuav tsum ua tib zoo xyuas cov nplais ntawm cov khoom kom oxidized. Yog tias muaj teeb meem, nws yuav tsum tau nqa tawm thaum lub sij hawm.
(2) Kev ntsuas kub thiab dej yuav tsum raug tswj thaum oxidation ntau lawm, tshwj xeeb tshaj yog tias qhov kub tsis siab tshaj 24 ° C. Kev ntxuav yuav tsum txaus kom tiv thaiv tsis tau cov khoom tsis raug los ntawm kev sib tsoo hauv qhov nqos zaws.
(3) Yuav tsum muaj ib tus neeg tshwj xeeb los tswj cov kev sib tsoo ntawm qhov sib tsoo, tswj kev xuas cov xim nicel ion, fluoride ion concentration, lub xeev tus nqi, thiab da dej kub hauv qhov teev tseg, thiab saib xyuas kev npaj thiab kev kho ntawm da dej.
(4) Yuav tsum tau kuaj qhov yuav tsum tau kuaj tom qab muab cov khoom tso rau 12 teev, kom cov ntaub ntawv yog qhov tseeb.
