3. Rwb thaiv tsev efficiency:
-Cov cov rwb thaiv tsev ua haujlwm ntawm lub thawv dej khov kom nkag siab ntev npaum li cas nws tuaj yeem muab tub yees rau cov tub yees rau zaub mov lossis dej haus. Qhov no yog qhov tshwj xeeb tshaj yog rau kev ua si sab nraum zoov ntev. Cov thawv dej khov zoo tuaj yeem muab kev tiv thaiv ntev dua.
4. Khoom siv:
-High cov thawv Ice Ice ua haujlwm feem ntau siv lub plhaub ntim thiab cov khoom siv rwb thaiv tsev (xws li polyurethane ua npuas ncauj). Cov ntaub ntawv no tuaj yeem muab cov rwb thaiv tsev zoo dua thiab ua kom muaj kev tiv thaiv hnyav thiab ntuag.
5. Portility:
-Cov kev yooj yim ntawm kev nqa lub khob dej khov. Yog tias koj nquag tau tsiv ntawm ib qho chaw mus rau lwm qhov, koj yuav xav tau ib lub thawv dej khov nrog lub log thiab rub kov. Lub caij no, qhov hnyav kuj yog qhov tseem ceeb los txiav txim siab, tshwj xeeb tshaj yog thaum muaj cov khoom.
6. Sealing thiab Dej Tsis kam:
-Qhov kev sib khi ua tau zoo tuaj yeem tiv thaiv cov cua sib pauv thiab ua kom zoo dua qub ceev. Lub caij no, lub thawv dej khov yuav tsum muaj qee qib ntawm cov dej tsis kam, tshwj xeeb yog tias koj yuav siv nws rau hauv huab cua huab cua.
7. Yooj yim los ntxuav thiab tswj:
-Xaiv lub thawv dej khov nrog qhov chaw du sab hauv uas yooj yim los ntxuav. Qee lub thawv dej khov yog tsim nrog cov qhov rau yooj yim ntws, uas tuaj yeem tau yooj yim ntws melted dej khov tom qab siv.
8. Nyiaj txiag:
-Cov tus nqi ntawm cov thawv dej khov thiab cov hnab ntim tau los ntawm kaum mus rau ntau pua leej huab cua, feem ntau yog txiav txim siab los ntawm qhov loj me, cov khoom siv, thiab cov haujlwm ntxiv. Raws li koj cov peev nyiaj thiab siv zaus, nqis peev hauv cov khoom lag luam zoo feem ntau yog kev siv tus nqi ntev.
9. Saib cov neeg siv tshuaj xyuas thiab hom npe nrov:
-Before ua qhov kev txiav txim siab zaum kawg los yuav, tshuaj xyuas lwm cov neeg siv kev tshuaj xyuas ntawm cov khoom tuaj yeem muab cov ntaub ntawv thiab cov ntaub ntawv siv tau. Xaiv lub npe zoo-paub hom feem ntau ua kom cov khoom lag luam zoo thiab cov neeg siv khoom zoo.
Los ntawm kev xav txog cov ntsiab lus saum toj no nkag siab, koj tuaj yeem xaiv lub khob dej khov lossis dej khov uas haum rau koj cov kev xav tau zoo tshaj plaws, kom cov khoom noj thiab dej txias nyob twj ywm thiab txias thaum xav tau.
Koj puas paub yuav ua li cas cov dej khov pob?
Kev tsim cov khoom lag luam hauv cov khoom lag luam hauv lub khob dej khov yuav tsum tau ua tib zoo tsim, xaiv cov ntaub ntawv tsim nyog, nruj nruj ua cov txheej txheem, thiab tswj kev tsim nyog. Cov hauv qab no yog cov kauj ruam raug rau kev ua cov khoom lag luam loj:
1. Cov theem tsim:
-Txoj kev tsom xam: txiav txim siab lub hom phiaj siv dej khov (xws li kev kho mob, thiab xaiv cov khoom siv, thiab lub sijhawm txias raws li cov xwm txheej sib txawv.
-Txhais kev xaiv: Xaiv cov ntaub ntawv tsim nyog kom tau raws li kev ua haujlwm thiab kev nyab xeeb ntawm cov khoom. Kev xaiv cov ntaub ntawv yuav cuam tshuam rau kev ua tau zoo rau cov kev ua tau zoo, ruaj, thiab kev nyab xeeb thiab kev nyab xeeb ntawm cov khoom siv hauv dej khov.
2. Cov Khoom Xaiv:
-Shell Cov Khoom Siv: Daus Dej, Dej, thiab Khoom Noj Khoom Haus Huv xws li Polyethylene, BRON, lossis PVC yog feem ntau xaiv.
-Cov: Xaiv cov gel tsim nyog tsim nyog los yog kua raws li kev siv ntawm cov dej khov. Cov khoom xyaw gel suav nrog polymers (xws li polymrylamide) thiab qee zaum cov tshuaj tiv thaiv kab mob xws li propylene glycol thiab cov tshuaj tiv thaiv ntxiv.
3. Kev tsim qauv:
-Qhov lub hnab ntim khoom lag luam: lub khauj khaum ntawm lub hnab dej khov yog tsim los ntawm tshuab moulding lossis cua sov sib khi thev naus laus zis. Tshuab moulding yog qhov tsim nyog rau kev tsim cov duab sib xyaw, thaum tshav kub khi yog siv los ua kom yooj yim hnab.
-Pilling: Sau cov gel premixed rau hauv dej khov lub plhaub hauv qab cov neeg tsis huv. Xyuas kom meej tias cov nyiaj puv tau tsim nyog kom tsis txhob muaj kev nthuav dav dhau los lossis xau dej.
-Sealing: Siv cov thev naus laus zis sib tsoo los txhawm rau kom cov ceev ntawm cov dej khov nab kuab thiab tiv thaiv kom tiv thaiv gel takeage.
4. Kuaj thiab Tswj Tswjhwm Zoo:
Kev Kuaj Xyuas-Kev Xeem: Kev sim txias ua kom ntseeg tau tias cov khoom siv dej khov ua tiav qhov kev ua tau zoo rwb thaiv tsev.
-Txoj kev kuaj: Txheeb xyuas txhua pob ntawm cov qauv los xyuas kom meej tias kev sib khi ntawm cov dej khov lub hnab ua tiav thiab xau.
Kev kuaj mob ntxiv: Kev siv dua tshiab thiab kho tshuab lub zog kuaj cov dej khov rau simulate cov xwm txheej uas yuav ntsib thaum siv sijhawm ntev.
5. Ntim thiab sau npe:
-Qhov khoom siv: Ntim kom loj raws li cov khoom yuav tsum tau los tiv thaiv kev ncaj ncees ntawm cov khoom lag luam kev thauj mus los thiab muag khoom.
-Txoj kev ua kom tau: Qhia cov ntaub ntawv tseem ceeb ntawm cov khoom lag luam, xws li cov lus qhia rau kev siv rau, cov khoom xyaw, ntau lawm hnub, thiab cov ua luam ntawm daim ntawv thov.
6. Logistics thiab faib:
-Cov rau kev lag luam xav tau, npaj khoom lag luam thiab cov khoom xa mus kom ntseeg tau tias cov khoom tseem nyob hauv cov neeg siv zoo ua ntej mus txog qhov kawg tus neeg siv.
Cov txheej txheem ntau lawm yuav tsum ua raws li kev nyab xeeb thiab ib puag ncig cov qauv los xyuas kom cov khoom muaj kev sib tw ua lag luam thiab muaj kev nyab xeeb los ntawm cov neeg siv khoom.
