Kev tsim cov corrugated cardboard yog cov txheej txheem kev lag luam tas mus li, feem ntau ua tiav ntawm cov kab ntau lawm. Cov txheej txheem yooj yim yog daim ntawv cog lus tiaj tus duab los qhia (daim ntawv ntsej muag thiab daim ntawv sab hauv) nrog cov ntawv corrugated core pressed rau hauv ib lub yoj duab, siv cov nplaum ua kom tiav ntau txheej txheej txheej.
Cov hauv qab no yog cov kauj ruam tseem ceeb tshaj plaws rau peb- txheej (ib corrugated) thiab tsib txheej (ob chav corrugated) cardboard:
1. Cov khoom siv tseem ceeb
Lub thawv ntawv: siv los ua cov txheej txheej saum npoo (lub ntsej muag daim ntawv thiab cov ntawv sab hauv) ntawm cov duab los qhia, muab cov ntawv luam tawm tiaj tus thiab cuam tshuam, feem ntau pom zoo li cowhide dai daim ntawv.
Corrugated core ntawv: ib hom ntawv siv rau nias rau hauv cov duab wavy, nrog zoo elasticity thiab compressive zog.
Adhesive: Nws feem ntau yog ua los ntawm pob kws hmoov txhuv nplej siab los yog cassava starch, thiab lwm yam additives qee zaum ntxiv los kho nws cov khoom.
Zog: feem ntau yog chav, siv rau cua sov thiab kev sib txuas ua ke.
2. Cov txheej txheem tsim khoom yooj yim (ua raws li hauv cov kab ntau lawm corrugated cardboard)
Ib txoj kab ntau lawm feem ntau suav nrog cov kauj ruam hauv qab no:
Raw daim ntawv tuav
Cov yob loj zoo li daim duab los qhia thiab corrugated core daim ntawv yog muab tso rau ntawm lub racking unwinding, npaj nkag mus rau cov kab ntau lawm.
Single facer tshuab: Nov yog txheej txheem tseem ceeb
Preheating: Cov ntawv tseem ceeb yog thawj rhuab los ntawm cov menyuam preheating kom nws hloov tau yooj yim thiab yooj yim rau daim ntawv.
Corrugated forming: Cov ntawv rhuab core yog dov los ntawm ib khub ntawm grooved corrugated rollers los ua ib tug nruam thiab zoo wavy qauv. Hom ridges muaj xws li A flute, B flute, C flute, E flute, thiab lwm yam.
Daim ntawv thov kua nplaum: Siv ib qho nyiaj ntawm cov hmoov txhuv nplej siab sib npaug rau saum lub ru tsev corrugated.
Bonding: Daim ntawv corrugated core coated nrog nplaum yog tam sim ntawd ua ke nrog ib txheej ntawm cardboard (lub ntsej muag daim ntawv los yog daim ntawv sab hauv) los ntawm cov thawj daim ntawv khib nyob rau hauv siab chais, ua ib tug - ib sab corrugated cardboard (ib sab yog tiaj daim ntawv thiab lwm sab yog corrugated).
Ob chav facer tshuab:
Rau peb - txheej boards: Muab cov corrugated nto ntawm ib sab - ib sab corrugated cardboard upwards thiab txuas mus rau lwm txheej ntawm cardboard (sab hauv ntawv).
Rau tsib lossis xya txheej boards: feem ntau, ob txheej ntawm ib qho - sab corrugated cardboard (thov los ntawm ib tug choj) yog ua ke nrog nruab nrab lub thawv ntawv (cov ntawv nruab nrab) ua ntej, thiab ces nkag mus rau ob - sab tshuab ua ke rau ntau - txheej sib txuas.
Nyob rau hauv ob lub -sab tshuab, daim ntawv ntawv hla los ntawm lub phaj kub (ib lub phaj tiaj tus rhuab los ntawm chav) thiab lub siab rau cov menyuam, thiab cov hmoov txhuv nplej siab gelatinizes, gelatum thiab solidifies nyob rau hauv kub siab kom ua tau ruaj khov adhesion. Cov txheej txheem no kuj tshem tawm qee cov dej noo ntawm daim duab los qhia.
Qhuav thiab txias
Cov ntawv cog lus sib txuas nkag mus rau chav ziab ziab (feem ntau txuas nrog cov phaj kub ntawm ob lub-sided tshuab), ntxiv evaporating noo noo thiab stabilizing cov qauv.
Tom qab ntawd, cov duab los qhia nkag mus rau hauv qhov chaw txias thiab txias los ntawm lub qhov cua los yog lub kiv cua kom huv si ua kom cov nplaum nplaum thiab rov ua kom lub tiaj tus ntawm cov duab los qhia.
Vertical thiab kab rov tav txiav
Longitudinal txiav thiab creasing tshuab: Raws li cov kev xav tau tshwj xeeb, siv rab riam ncig los txiav cov duab los qhia dav rau hauv qhov xav tau dav raws li cov kev taw qhia ntawm kev mus ncig, thiab nias txoj kab crease ntawm txoj haujlwm.
Hla txiav tshuab (feem ntau yog lub computer-tswj): Ua kom raug txiav cov duab los qhia txuas mus rau qhov ntev.
Stacking thiab ntim
Cov ntawv txiav ib leeg yog txiav rau hauv pawg, khi los ntawm lub tshuab strapping, thiab tom qab ntawd xa mus rau lub tshuab ua cov duab los qhia rau kev luam ntawv tom ntej, tuag- txiav, slotting, nailing, los yog cov txheej txheem sib txuas.
3. Cov hom tseem ceeb thiab txheej ntawm flutes
Ib qho corrugated (peb txheej): daim ntawv nto + ib txheej ntawm corrugated + ntawv sab hauv. Cov hom corrugations feem ntau suav nrog B-corrugations (zoo thiab hloov tau rau kev luam ntawv), C-corrugations (siab balanced), thiab E-corrugations (zoo corrugations nrog ilv zoo nkauj).
Muab ob npaug rau corrugated (tsib txheej): daim ntawv nto + ib txheej ntawm corrugated + ntawv nruab nrab + lwm txheej ntawm corrugated + daim ntawv sab hauv. Kev sib xyaw ua ke xws li BC ribs, BE ribs, thiab lwm yam tuaj yeem coj mus rau hauv tus account cov yam ntxwv ntawm cov kab sib txawv (xws li flatness ntawm B tav thiab buffering ntawm C tav).
Peb corrugated (xya khaubncaws sab nraud povtseg): siv rau hnyav - lub luag hauj lwm ntim uas yuav tsum tau muaj zog heev.
4. Cov hauv paus ntsiab lus
Lub hauv paus ntawm cov qauv corrugated yog ib qho kev tsim qauv: cov ntawv tiaj tus yog nias rau hauv qhov nruam arched tsis muaj zog, uas tuaj yeem cuam tshuam lub siab ntsug rau hauv lub dav hlau kev ntxhov siab ntawm cov duab los qhia, lawv yuav txhim kho cov ntug compression zog thiab cushioning kev ua tau zoo ntawm cov duab los qhia, thaum tuav lub teeb ntawm cov khoom.
Nyob rau hauv luv luv, corrugated cardboard ntau lawm yog ib tug npaum thiab tas mus li automated txheej txheem uas transforms zoo tib yam yob ntawv rau hauv ntim cov ntaub ntawv uas zoo heev mechanical zog los ntawm cua sov, sib sau, gluing, nias, thiab ziab curing.
