Hauv peb lub neej niaj hnub, corrugated cardboard thawv yog cov khoom ntim khoom siv rau txhua yam los ntawm cov khoom siv hauv tsev loj heev rau cov khoom lag luam nrawm. Hauv kev muaj tiag, nws cov txheej txheem tsim khoom yog cov cuab yeej siv tau zoo uas sib xyaw cov khoom siv hluav taws xob, kev tsim vaj tsev, thiab cov ntaub ntawv tshawb fawb.
Cov kauj ruam hauv qab no suav nrog tag nrho cov txheej txheem corrugated cardboard lub thawv tsim khoom, los ntawm cov khoom siv raw mus rau cov khoom tiav:
1. Cov khoom siv raw yog ua los ntawm corrugated cardboard.
Corrugated cardboard, uas muaj peb yam tseem ceeb, yog lub ntsiab ntawm corrugated cardboard thawv:
Lub thawv ntawv lub thawv: tiaj tus, du, thiab pom nyob rau hauv cov txheej sab hauv thiab sab nraud, nws muaj kev cuam tshuam tsis zoo thiab qhov chaw luam ntawv.
Corrugated core ntawv: Lub thawv ntawv lub hauv paus yog ua los ntawm cov ntawv corrugated, uas yog rhuab thiab compressed los tsim cov duab wavy. Zoo ib yam li tus choj koov, cov nthwv dej no- zoo li kev tsim kho muaj peev xwm compressive thiab buffering zoo thaum faib cov siab ntsug.
Adhesive: Muaj zog thiab ib puag ncig tus phooj ywg, pob kws hmoov txhuv nplej siab yog feem ntau siv.
Corrugated cardboard yog muab faib ua ntau yam qauv raws li qhov ceev thiab qhov siab ntawm cov qauv wavy; daim ntawv nrov tshaj plaws yog:
A flute: Qhov siab tshaj plaws thiab zoo tshaj plaws buffering.
B flute: ntau ntom, tiaj, thiab tiv taus siab.
C flute: Kev ua tau zoo tag nrho, qhov chaw nruab nrab ntawm A thiab B.
E flute: Lub thinnest thiab thinnest, nquag siv rau xim - luam tawm ntim (xws li cov xov tooj) lossis cov khoom siv me me uas tsis yooj yim.
2. Kev tsim khoom ntawm corrugated cardboard
Hloov cov ntawv nyoos rau hauv lub tiaj tus, compression-cov ntawv pov thawj yog qhov tseem ceeb tshaj plaws. Cov txheej txheem tseem ceeb hauv cov txheej txheem no, uas yog ua los ntawm kev ua haujlwm siab -ceev corrugated cardboard ntau lawm kab, yog:
Preheating: Txhawm rau tswj cov dej noo thiab lav qhov ruaj khov nyob rau hauv lub neej yav tom ntej, pub cov yob- zoo li daim ntawv nyoos (lub thawv ntawv thiab cov ntawv tseem ceeb) rau hauv lub tshuab.
Rolling corrugated: Ob rhuab corrugated rollers nias cov ntawv tseem ceeb rau hauv cov qauv wavy predetermined.
Kev siv cov kua nplaum thiab kev sib txuas: Ua raws cov corrugated peaks rau hauv daim ntawv sab hauv thiab sab nrauv los ntawm kev siv cov kua nplaum rau lawv.
Moulding thiab txias: Tom qab cov kua nplaum tau qhuav lawm, cov duab los qhia yog siv lub phaj kub thiab siv txoj hlua khi nrog qhov kawg txias.
Ntsug thiab kab rov tav txiav: Nyob ntawm cov lus qhia tshwj xeeb ntawm kev txiav txim, txiav cov ntawv dav dav txuas mus rau hauv daim duab plaub ntawm qhov loj me.
Tam sim no peb tau txais cov ntawv loj loj, tiaj tus corrugated cardboard uas yog npaj txhij mus rau kauj ruam tom ntej.
3.Printing thiab slotting
Lub tshuab luam ntawv tuag- txiav tshuab lossis tshuab luam ntawv slotting yuav tsum tau hloov cov duab los qhia loj rau hauv cov thawv ntawv uas tuaj yeem ntim tau. Cov txheej txheem no muab ob peb kauj ruam:
luam ntawv
Cov txheej txheem siv ntau tshaj plaws rau kev luam ntawv cov thawv ntawv yog flexographic luam ntawv. Dej-raws li tus cwj mem (ua kom qhuav sai, eco-tus phooj ywg) tuaj yeem xa mus los ntawm cov menyuam mesh siv cov roj hmab lossis cov phaj resin. Cov ntawv nyeem, kab, thiab cov qauv xim yooj yim tuaj yeem luam tawm nrog nws.
Offset printing: Offset printing feem ntau yog ua hauj lwm thaum pib thaum luam ntawv siab - cov qauv xim muaj tseeb (xws li cov thawv ntawv hauv khw muag khoom), tom qab ntawd cov ntawv luam tawm tau muab tso rau hauv corrugated cardboard.
Qhov: Txhawm rau tsim plaub lub pob zeb npog (sab sauv thiab sab saud) ntawm lub thawv thaum yav tom ntej folding, txiav V- lossis U- zoo li cov slots ntawm daim duab los qhia ntug.
Indentation: Nias cov kab nrib pleb rau ntawm daim duab los qhia siv pwm. Cov theem no yog qhov tseem ceeb vim tias qhov tseeb indentation tau lees paub tias lub thawv ntawv tuaj yeem raug molded thiab folded smoothly ntawm cov txheej txheem ntim khoom.
Punching/buttoning: Qhib lub qhov los yog qhov cua qhov, nyob ntawm seb qhov specifications.
Tuag- cov tshuab txiav feem ntau yog siv rau kev txiav txim me me lossis cov thawv txawv txawv. Siv lub rooj ntoo riam pwm tsim raws li cov qauv thiab stamping intricate duab thiab indentations tag nrho ib zaug yog zoo li ci ncuav qab zib.
4. Tsim thiab Bonding
Thaum lub slotted cardboard tau luam tawm, nws yuav tsum tau fastened rau hauv ib lub thawv ib thooj ntawm ib lub sij hawm:
Ntsia lub thawv: Ruaj ntseg ntawm daim duab los qhia lub seams nrog galvanized ca hlau hlau. Lub zog siab, ceev ceev, thiab haum rau hnyav - lub luag haujlwm ntim yog cov txiaj ntsig; lub taub hau hlau lub peev xwm los corrode los yog khawb rau sab hauv yog ib tug drawback.
Adhesive kem: Txhawm rau muab cov hlua khi, siv eco- cov phooj ywg dawb latex. Cov txiaj ntsig suav nrog kev saib du, tsis muaj kev puas tsuaj rau cov ntsiab lus, thiab kev txuag chaw cia. Tsis siv neeg lub thawv gluing tshuab, uas muaj txiaj ntsig zoo heev, twb tau siv dav hauv cov tuam txhab loj hauv cov thawv ntawv.
Packing: Yuav kom xa mus rau cov neeg siv khoom yooj yim dua, ua kom cov thawv ntim khoom ua tau zoo thiab siv lub tshuab ntim khoom los ntim rau hauv pawg.
Txhawm rau tsim cov thawv ntawv corrugated, daim ntawv hloov pauv yuav tsum ua ntej lub cev deformed (corrugated dov) kom muaj zog. Qhov no yog ua raws li kev siv tshuab (tuag-txiav, indentation) uas muab cov ntawv geometric logic (folding forming). Ntxiv nrog rau kev ua lub thawv ntim khoom, nws muaj cov qauv tsim qauv uas pheej yig, tsim qauv, thiab rov ua dua tshiab hauv cov txheej txheem logistics niaj hnub.
