Abstract: Daim ntawv txheeb xyuas daim ntawv thov thiab kev txhim kho ntawm cov ntsiab lus tseem ceeb ntawm cov txheej txheem kub, thiab kev ntxhias ntawm cov nyiaj, cov av noo ntau ntawm cov cuab yeej kev ua haujlwm, thiab cov tseev kom muaj ntawm cov ntaub ntawv raw, thiab lwm yam.
Cov qauv ua kua thiab kom tsis muaj menyuam tau muaj ntau xyoo. Hauv Suav teb, vim yog kev txhim kho cov kuab dawb, yuav luag txhua tus tau siv los tsim cov ntim tsheb ntau-kub ua noj. Tam sim no, cov kuab tshuaj nplaum tau dhau los kaum xyoo kev txhim kho hauv cov cuab yeej, cov khoom tseem ceeb hauv cov cuab yeej, cov ntaub ntawv raw, cov neeg ua haujlwm, thiab thev naus laus zis. Hauv cov ntsiab lus ntawm kev tiv thaiv kev tiv thaiv ib puag ncig hauv kev tiv thaiv kev tiv thaiv tau tsim cov khoom tsim kho kom zoo dua rau cov khoom tsim kho kom zoo dua rau cov khoom tsim kho kom zoo dua qub. dav, thiab qhob xyab, kom tsis muaj menyuam, thiab ntim yog ib qho ntawm lawv.
1.Qhov lub tswv yim ntawm kev ua noj ua kom tsis muaj menyuam thiab siv cov kuab tshuaj dawb dawb
Ua noj kom tsis muaj menyuam yog cov txheej txheem ntawm kev khi thiab tua cov kab mob hauv airtight ntim los ntawm kev thov nias thiab cua sov. Nyob rau hauv cov nqe lus ntawm daim ntawv thov qauv, lawb thiab ntim khoom tsis muaj menyuam yog faib ua ob hom: yas thiab txhuas-cov qauv qauv. Cov kev ua noj ua haus tau muab faib ua ob theem: kev kub siab ua noj (saum 100° C rau 121° C) thiab kev kub siab ua noj (siab dua 121° C txog 145° C). Cov kuab tshuaj dawb cov nplaum tuaj yeem tam sim no cov khoom noj kom tsis muaj menyuam tsis muaj menyuam nyob ntawm 121° C thiab hauv qab no.
Nyob rau hauv cov nqe lus ntawm cov khoom siv tau, cia kuv qhia luv luv ntawm cov khoom siv ntawm Kangda:
Cov qauv yas: WD8116 tau tshaj tawm dav thiab sib txawv ntawm cov ny / RCPP ntawm 121° C;
Aluminium Yas qauv: Daim ntawv thov ntawm WD8262 hauv Al / RCPP ntawm 121° C kuj yog heev heev.
Nyob rau tib lub sijhawm, hauv kev ua noj ua haus thiab kom tsis muaj menyuam cov qauv, qauv nruab nrab, cov ethyl maltol) kam ua tau zoo heev.
2.Qhov kev qhia yav dhau los ntawm kev ua kom siab kub
Ntxiv nrog rau tus paub peb - thiab plaub txheej qauv, cov ntaub ntawv tseem ceeb siv yog tsiaj, al, NY, thiab RCPP. Txawm li cas los xij, lwm yam khoom siv tau pib siv rau kev ua noj ua lag luam ntawm kev ua lag luam, ntau li cov duab sib dhos, thiab lwm yam, lawv tsis tau siv rau ntawm cov khoom loj lossis cov khoom loj Hauv paus rau lawv cov ntawv thov thoob plaws tseem yuav tsum tau kuaj xyuas lub sijhawm ntev dua thiab muaj cov txheej txheem tiag tiag.
Tsis tas li ntawd, cov kuab nplaum dawb kuj tseem tab tom txhim kho lawv cov kev ua tau zoo ntawm cov khoom tsis muaj menyuam. Tam sim no, kev nce qib tseem ceeb tau ua nyob rau hauv cov ntaub ntawv pov thawj kev ua tau zoo ntawm Konda cov ntaub ntawv tshiab 'cov kuab tshuaj dawb nyob rau hauv tej yam kev mob ntawm 125° C thiab 128° C, thiab kev siv zog tau ua kom ncav cuag cov kev ua noj ntau dua, xws li 135° C ua thiab txawm tias 145° C ua.
3.Key cov ntsiab lus ntawm daim ntawv thov thiab cov txheej txheem tswj
3.1Teeb tsa thiab kev pom zoo ntawm cov nplaum
Tam sim no, cov khoom siv ntawm cov khoom siv dawb pub dawb, thiab muaj ntau cov tuam ntxhab tau txais kev paub ntau dua thiab kev pom hauv kev siv cov khoom siv kuab tshuaj. Txawm li cas los xij, qhov kev ua kub kub ua noj kom tsis muaj menyuam yaus tsis muaj txiaj ntsig), thiab cov nplaum tuab), thiab cov nplaum tuab), thiab cov nplaum uas tsis muaj peev xwm ua kom muaj kev xav tau. Yog li ntawd, thaum siv cov kuab tshuaj dawb rau cov khoom noj ua haus, cov nyiaj ua tau zoo yuav tsum tau nce, nrog cov khoom siv kom zoo ntawm 1.8-2.5g / m².
3.2 Cov av noo ntau ntawm ib puag ncig
Tam sim no, ntau tus tuam ntxhab tau pib paub thiab txuas qhov tseem ceeb rau kev cuam tshuam ntawm cov khoom ib puag ncig ntawm cov khoom zoo. Tom qab ntawv pov thawj thiab cov ntsiab lus ntawm ntau cov tswv yim muaj ntau cov tswv yim, nws pom zoo kom tswj hwm cov av noo ib puag ncig ntawm 40% thiab 70%. Yog tias cov av noo qis dhau, nws yuav tsum tau noo, thiab yog tias cov av noo siab dhau, nws yuav tsum tau dehumidified. Vim tias ib feem ntawm cov dej nyob hauv ib puag ncig koom nrog ntawm cov tshuaj tua kab thiab ua rau muaj qee yam dej tsis zoo, yog li cuam tshuam rau qhov kev ua tau kub siab thaum ua noj. Yog li ntawd, nws yog qhov tsim nyog los kho cov kev teeb tsa ntawm A / B cov txheej txheem me ntsis hauv cov chaw huab cua siab thiab huab cua huab cua.
3.3 Cov chaw ntsuas rau cov cuab yeej ua haujlwm
Parameter chaw yog teeb raws li cov qauv sib txawv thiab kev teeb tsa; Qhov nro teeb tsa thiab qhov tseeb ntawm cov kev faib tawm ntawm cov kev sib piv yog txhua yam ntawm kev tswj thiab kev pom zoo. Cov qib siab ntawm kev siv tshuab, kev ua haujlwm zoo, thiab cov khoom siv yooj yim, tab sis nws tseem npog qhov tseem ceeb thiab kev ceev faj tom qab nws. Peb ib txwm hais txog tias cov kev ua haujlwm pub dawb yog qhov ua kom tsis zoo.
3.4 Tej yam yuav tsum muaj cov ntaub ntawv raw
Zoo Flatness, nto wettability, shrinkage tus nqi, thiab noo noo tus lej ntawm cov ntaub ntawv nyias nyias yog qhov tsim nyog rau ua tiav cov khoom siv sib xyaw.
- Qhov zoo ntawm cov kuab tshuaj dawb
Tam sim no, kev ua kub ua thiab txias thiab cov khoom kom tsis muaj menyuam hauv cov lag luam tsuas siv cov kuab tshuaj nplaum raws cov nplaum rau cov khoom sib xyaw qhuav. Piv rau cov kev sib xyaw qhuav, siv cov kuab tshuaj ntsuab sib xyaw ua khoom noj muaj cov txiaj ntsig hauv qab no:
4.1Xyaum Ua Zoo
Qhov kom zoo dua ntawm kev siv cov kuab tshuaj dawb yog feem ntau nce nyob rau hauv muaj peev xwm ntau lawm. Raws li yog paub zoo, siv cov tshuab siv tshuab qhuav los ua cov txheej txheem kub siab thiab cov khoom tsis muaj menyuam muaj cov khoom tsis muaj menyuam ua kom tsis muaj zog, feem ntau nyob ib ncig ntawm 100m / min. Qee cov khoom siv thiab kev tswj kev tsim khoom yog qhov zoo, thiab tuaj yeem ua tiav 120-130m / min. Txawm li cas los xij, cov xwm txheej tsis zoo, tsuas yog 80-90m / min lossis txawm qis dua. Cov khoom tshwm sim yooj yim ntawm cov kuab tshuaj nplaum thiab cov khoom siv sib xyaw ua tau zoo dua li ntawm cov khoom siv qhuav, thiab cov tshuaj sib xyaw uas tuaj yeem ncav cuag 200m / min.
4.2nqi txiaj ntsig
Qhov ntau npaum li cas ntawm cov kua nplaum siv rau cov kuab tshuaj raws li kub ua noj kua nplaum yog qhov loj, ib txwm tswj ntawm 4.0g / m² Sab laug thiab sab xis, qhov kev txwv tsis tsawg dua 3.5g / m²;Txawm hais tias muaj cov kua nplaum thov mus rau cov kuab tshuaj dawb ua noj kua nplaum yog 2.5g / m² Piv rau cov kuab tshuaj raws li txoj kev, nws kuj muaj tus nqi siv tus nqi tseem ceeb vim nws cov ntsiab lus siab.
4.3Qhov zoo hauv kev tiv thaiv kev nyab xeeb thiab ib puag ncig
Thaum siv cov kuab tshuaj raws li kub ua noj kua nplaum, muaj ntau ntawm kev tiv thaiv kev tiv thaiv, uas muaj kev tiv thaiv ib puag ncig thiab kev siv hluav taws xob ntau. Nws tseem yog ib qho tseem ceeb rau cov teeb meem ntawm cov kuab tshuaj siab siab. Thiab cov kuab tshuaj dawb tsis muaj kev txhawj xeeb zoo li no hlo li.
4.4Zog txuag tau zoo
Kev kho tus piv ntawm cov kuab tshuaj nplaum raws cov khoom nplaum muaj cov khoom lag luam yog tus muaj siab, yeej yog ntawm 50° C lossis saum toj no; Lub sijhawm tiav yuav tsum yog 72 teev lossis ntau dua. Cov tshuaj tiv thaiv ceev ntawm cov kuab tshuaj dawb ua kua nplaum yog qhov tseem ceeb, thiab qhov kev thov kom kho qhov kub thiab lub sijhawm kho kom qis dua. Feem ntau, kev kho qhov kub yog 35° C ~ 48° C, thiab lub sijhawm kho tau yog 24-48 teev, uas tuaj yeem pab kom cov neeg siv khoom lag luam luv luv lub voj voog.
5.Cov
Hauv cov ntsiab lus, cov kuab nplaum dawb, vim lawv cov khoom lag luam tshwj xeeb, cov khoom lag luam nplaum tau koom tes thiab kev txhawb nqa thiab kev paub hauv lawv cov laj thawj. Peb ntseeg tias cov kuab tshuaj dawb muaj cov khoom siv dav dav ntawm Kangda cov ntaub ntawv tshiab yog "peb tau ua haujlwm hnyav los tsim tus nqi rau cov neeg siv khoom thiab txav lawv". Peb cia siab tias peb cov khoom lag luam siab tshaj tuaj yeem pab ntau cov xim luam ntawv ntau dua los tshawb xyuas cov kuab tshuaj tsis zoo tshiab.
