Thaum lub caij nplooj zeeg thiab lub caij ntuj no, raws li qhov kub thiab txias poob, huab cua kuj ua kom qhuav. Thaum cov chaw ntim khoom tsim cov thawv ntawv, muaj qhov nyiam ntawm daim ntawv tawg, uas tsis yog tsuas yog ua rau cov khoom pov tseg xwb tab sis kuj nce cov nqi tsim khoom ntawm cov lag luam. Yog li, yuav daws qhov teeb meem no li cas?
Kev txhim kho kev ntsuas 1: Khaws ib puag ncig cov av noo thaum khaws cia hauv lub tsev rau khoom
Mobile humidification, pem teb sprinkling humidification, thiab nruab nrab humidification yog tag nrho cov muaj txiaj ntsig rau kev txhim kho qhov tsim nyog ntawm cov txheej txheem tsim ntawv.
Kev Txhim Kho Kev Ntsuas 2: Ua kom cov av noo nyob rau sab nraub qaum thaum lub sijhawm tshaj tawm - txheej txheem lamination
Thaum ua ntawv thov cov yeeb yaj kiab, siv lub tshuab humidifier ultrasonic kom humidify lub backside ntawm daim ntawv los txhim kho nws cov softness.
Kev Txhim Kho Kev Ntsuas 3: Ntawv Humidification
1. Cov ntawv uas tseem nyob hauv ib puag ncig qhuav ntev los yog qhuav tom qab txheej txheej yuav ua rau poob dej, ua rau crease, tawg, thiab lwm yam teeb meem thaum tuag- txiav.
2. Siv dej rau hauv daim ntawv kom ntub dej, ua kom nws yooj yim dua, thiab tom qab ntawd ua tiav kev tuag- txiav thiab creasing tuaj yeem txo qhov tshwm sim ntawm cov teeb meem no.
Piv txwv li: Watering lub tshuab luam ntawv (hauv qab ntawm daim ntawv)
Piv txwv li: Hloov cov roj txheej hauv lub tshuab txheej nrog dej huv (tsis qhuav)
Kev Txhim Kho Kev Ntsuas 4: Kev xaiv qhov kev xaiv ntawm cov hlua khi hlua khi thaum tsim khoom
Raws li SOP, xaiv qhov tsim nyog indentation riam thiab indentation strip
1. Ntsuas lub thickness ntawm daim ntawv ua ntej ➨ Piv txwv li: 0.31mm
2. Xaiv rab riam uas tsim nyog ➨ Xaiv 1.0mm
Lub hnab ntawv yuav tsum xav txog tias lub vojvoog folding ntawm ob - txheej ntawv txoj haujlwm yog txaus los tiv thaiv qhov nro sab nraud ntawm qhov indentation. Qhov dav ntawm qhov indentation riam yog pom zoo kom nce los ntawm ib theem.
3. Xaiv qhov tseeb indentation strip ➨ Xaiv qhov siab ntawm 0.4mm x dav ntawm 1.6mm
Kev suav ntawm indentation strip qhov siab: Ntawv thickness + 0.05mm=0.31 + 0.05=0.36mm
Kev suav ntawm indentation strip dav: Ntawv thickness x 2.0 + indentation riam=0.31 mm x 2.0 + 1.0mm=1.62 mm
Kev Txhim Kho Kev Ntsuas 5: Ua kom qhov dav dav dav thiab txo qhov siab tsis zoo thaum lub sijhawm tsim khoom.
Kev Txhim Kho Kev Ntsuas 6: Cov ntsiab lus ntawm lub tshuab tsis siv neeg lub hnab ntim khoom hauv cov txheej txheem ntau lawm
Hauv qab - nqa lub tshuab nqa ntawm tes tsis siv neeg- tuav lub hnab ntim tshuab feem ntau yuav ua rau daim ntawv tawg piv rau kev tsim lub hnab ntim. Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb los tswj qhov kub thiab av noo ib puag ncig (23 ± 3 degree, 50 ± 5%) txhua lub sijhawm.
2. Thaum lub sij hawm nias, hauv qab ntawm qhov yooj yim -tearable cheeb tsam yog relieved ntawm siab, thiab ib tug buffer cheeb tsam ntawm txog 1 cm yog tseg. Qhov no muaj qee yam kev txhim kho ntawm cov txheej txheem tearing.
Qhov ntau- txheej txheej folds tawg, feem ntau tshwm sim nws tus kheej thaum lub hnab tsim.
Qhov ua rau bursting:
① Cov ntawv yog tuab, muaj qhov tawv tawv, tsis muaj folding endurance, thiab ib puag ncig kub thiab av noo tsawg dhau, tsis muaj txheej;
② Cov kab tuag tsis yog tus qauv, thiab txiav ntau yam;
③ Lub hnab - txoj kev tsim tsis yog tus qauv, cov kab tuag tsis zoo sib xws, thiab lub zog folding muaj zog heev.
Cov chaw tawg yooj yim ntawm tes-cov hnab ntim khoom - cov ces kaum sab hauv thiab cov kab sab hauv sab hauv.
Kev tawg ntawm cov ces kaum sab hauv thiab sab hauv cov kab nrib pleb (tus ntoo khaub lig- zoo li thaj chaw) feem ntau yog tshwm sim los ntawm kev ncab lub hnab:
① Cov ntawv yog tuab, muaj zog nruj, tsis muaj folding endurance, thiab ib puag ncig kub thiab av noo tsawg dhau;
② Cov kab tuag tsis yog tus qauv, ntau qhov kev txiav yog tsim, thiab lub hnab hom yog dav thiab nyuaj rau qhib;
③ Lub hnab - txoj kev tsim tsis yog tus qauv, thiab qhov kev ncab tsis zoo.
Thaum lub caij nplooj zeeg qhuav thiab lub caij ntuj no, ntau tus phooj ywg hauv kev lag luam ntawv thiab thawv ntawv feem ntau hais txog ntau yam teeb meem xws li cov npoo tawg ntawm daim ntawv, cov npoo tawg hauv lub thawv, thiab cov kab tawg los yog tawg. Tam sim no, cia peb txheeb xyuas qhov ua rau ntawm cov npoo tawg no thiab cov yam ntxwv uas cuam tshuam rau lawv.
Analysis ntawm lub hauv paus ua rau ntawm daim ntawv lub thawv tawg kab:
1. Lub zog tensile ntawm cov ntawv sab hauv thiab sab nrauv txo qis, thaum lub rigidity ntawm cov ntawv ntawv nce, yog li ua rau muaj peev xwm tawg kab hauv lub thawv ntim khoom.
2. Lub tiaj tus nias lub zog ntawm cov ntaub ntawv tseem ceeb nce, thaum lub toughness ntawm daim ntawv sab hauv thiab sab nrauv txo. Thaum lub sij hawm tus txheej txheem ntawm kev thov cov kab tawg, cov ntaub ntawv sab hauv yog yooj yim puas, uas ua rau tawg kab ntawm lub thawv.
3. Lub inter- txheej sib khi lub zog ntawm daim ntawv dawb tsis txaus. Lub zog sib txuas sab hauv ntawm lub thawv ntawv yog qhov teeb meem uas lub thawv ntim khoom lag luam feem ntau saib dhau.
2. Cov yam ntxwv cuam tshuam rau qhov tawg ntawm lub thawv seams:
1. Kev cuam tshuam ntawm ib puag ncig kub thiab av noo, tshwj xeeb tshaj yog tswj cov dej noo. Thaum cov dej noo qis dua 60%, cov seams feem ntau yuav tawg.
2. Qhov tsis muaj zog lub kua muag tsis kam ntawm lub thawv ntawv, qhov ntau nws yog tawg. Feem ntau hais lus, kraft ntawv yog tsim kua muag ntau dua -tiv taus dua li ntawv tsis muaj coated; softwood pulp yog tsim kua muag ntau dua -resistant dua hardwood pulp; daim ntawv ua los ntawm cov khoom siv raw yog tsim kua muag ntau dua -resistant dua li cov ntawv siv dua.
3. Cov khaubncaws sab nraud povtseg ntau dua, qhov ntau dua nws yuav ua rau cov xov hlau tawg. Piv txwv li, triple -ply cardboard yog feem ntau ua rau cov hlau tawg ntau dua ob -ply cardboard; ob -ply cardboard yog feem ntau ua rau hlau tawg ntau dua ib zaug -ply cardboard.
4. Qhov ntau dua qhov sib txawv ntawm cov ntawv thiab cov ntaub so ntswg kom muaj nuj nqis hauv lub thawv, qhov ntau dua yuav tawg cov seams.
Kev ua haujlwm tsis raug thaum lub sijhawm ua haujlwm ntawm lub tshuab luam ntawv tuaj yeem ua rau cov thawv ntawv tuaj yeem tawg cov seams.
6. Qhov ntau dua lub zog ntawm daim ntawv, qhov ntau dua nws yuav tawg cov xov.
