Kho txoj kev ntawm cov raj cua kub tsis zoo

(I) qhov tseem ceeb ntawm kev kho cov khoom puas

Hauv kev tsim cov hluav taws xob cua sov, cov khoom siv tsis zoo yog qhov ua tau zoo hauv qab no 0}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} 3-5% . Yog tias cov khoom siv tsis zoo, tab sis kuj tau txuag cov khoom siv tsis zoo, tab sis kuj tseem txuag tau cov khoom siv tsis xws luag, thiab cov ntaub ntawv txo qis, cov ntaub ntawv txo qis, cov ntaub ntawv uas tsis haum, cov ntaub ntawv, thiab ua haujlwm tau yuav tsum tau.

(II) Qhov tau txais kev kho kom haum cov khoom lag luam hauv kev tsim cov hluav taws xob cua sov cov ntsiab

Feem ntau hais lus, tom qab lub tshuab hluav taws xob ua tau yooj yim, nws pom tias cov khoom siv hluav taws xob tsis yooj yim los kho, peb tau pom tias qee tus tuaj yeem kho .

1. Dab tsi yog dab tsi ntawm cov khoom siv hluav taws xob tsis zoo yuav kho tau:

Thaum cov teeb meem hauv qab no tshwm sim hauv kev muab tub lim ntawm cov hluav taws xob cua sov-cov hmoov hluav taws xob muaj zog, cov hom hluav taws xob hluav taws xob muaj peev xwm kho tau .

Ib qho kev ua tau zoo ntawm thawj cov hmoov magnesium yog qhov zoo . Thaum lub ntsiab lus hluav taws xob tau muab tso rau hauv {} Thaum lub taub hau hluav taws xob tau muab tso rau hauv} nqus {{4 4}} Thaum lub raj nqaij ntawm ob qho kawg yog txiav qhib, liab ink nqus tau ntau dua 2mm}

B thaum lub sij hawm ua ntawm lub tshuab hluav taws xob hluav taws xob, cov hmoov hlau magnesium yog me ntsis puas ntsoog:

Xws li flange vuam ntawm ob qho kawg ntawm cov roj rhaub yeeb nkab yeeb nkab cov yeeb nkab, (hydrochloric acid, nitrical acctruction kua {}}}

C Ib qho xwm txheej lwm yam: xws li lub raj hluav taws xob cua sov tsis tau ua kom sov, tab sis lub zog cua sov dhau los yog qhov kub thiab txias dhau lawm, thiab lwm yam .

2. Cov xwm txheej dab tsi ua rau cov khoom siv hluav taws xob tsis zoo uas tsis tuaj yeem kho tau:

Ib qho laj thawj rau cov hmoov magnesium: tsis zoo ntawm cov thawj magnesium thiab lwm cov ntsiab lus ntawm cov tshuaj tsis zoo, ceev ceev lossis tsis sib xws .

B {{0} Cov yeeb nkab ntawv: xws li cov kab nrib pleb, burrs sab hauv cov yeeb nkab, bubbles, shrinkage qhov, thiab lwm yam.

C {. Cov teeb meem hauv cov yeeb nkab tsim: xws li cov cua kub uas tawg lossis sib tsoo ntawm cov cua kub xaim, thiab lwm yam}
