Taug kev mus rau hauv ib lub café niaj hnub no, kua txiv hmab txiv ntoo, lossis nrawm- lub tsev noj mov niaj hnub no, thiab koj yuav pom qhov hloov pauv me me tab sis muaj txiaj ntsig zoo nyob hauv koj lub khob haus. Cov raj yas zoo nkauj zoo nkauj uas ua rau thaj chaw haus dej haus rau ntau tshaj li ib nrab xyoo pua tau ploj mus, hloov los ntawm kev sib txawv ntawm qhov sib txawv. Tsav los ntawm kev nruj cov kev cai hauv nroog, cov hom phiaj kev ruaj ntseg ntawm cov tuam txhab, thiab cov nthwv dej hnyav ntawm cov neeg siv khoom ib puag ncig kev nco qab, ib leeg - siv cov straws polypropylene tau so haujlwm ntau heev. Nyob rau hauv lawv qhov chaw, kev lag luam khoom noj khoom haus thoob ntiaj teb tau txais kev txo hwj chim daim ntawv straw.
Rau cov neeg siv khoom xws li, daim ntawv -raws li cov raj dej haus yuav zoo li ib qho yooj yim ntawm daim duab los qhia. Txawm li cas los xij, hloov cov yas- cov khoom siv los ntawm cov khoom siv dej tsis zoo thiab tsis muaj kev puas tsuaj - nrog cov substrate ib txwm ua rau nqus dej noo yog ib qho nyuaj tshaj plaws hauv kev ntim khoom niaj hnub no. Yog hais tias ib lub straw tsim tsis zoo, nws yuav dhau los ua qhov tsis zoo, ntxhov siab nyob rau hauv kaum feeb ntawm zaum hauv kas fes iced, instantly souring tus neeg siv khoom noj.
Tsim kom muaj kev vam khom, hwm daim ntawv straw yog ib txheej txheem kev lag luam zoo heev. Nws yuav tsum muaj kev sib yuav tsis zoo ntawm cov khoom siv science, chemical engineering, thiab siab -kev ceev cov tshuab precision. Txhua lub straw uas ua tiav nws cov duab hauv cov dej qab zib carbonated los yog tuab smoothie yog los ntawm kev ua tib zoo sib npaug ntawm daim ntawv hnyav, khoom noj khoom haus -qib nplaum cov qauv, thiab automated winding dynamics. Cov kab lus no rub rov qab cov ntaub thaiv rau hauv pem teb Hoobkas niaj hnub los tshawb xyuas raws nraim li cas cov ntoo tawv ntoo tau hloov mus rau hauv cov khoom siv ruaj khov, eco- cov khoom siv dej haus.
Raw Material Xaiv: Lub hauv paus ntawm Durability
Lub neej voj voog ntawm lub siab - cov ntawv straw zoo pib ntev ua ntej txhua lub tshuab pib tig. Txhua yam nyob ntawm kev muab cov khoom siv raw uas tuaj yeem ua rau tib lub sijhawm tiv taus cov kua dej immersion, tswj cov txheej txheem rigidity, thiab nyob ruaj ntseg rau tib neeg noj.
Cov khoom xyaw tseem ceeb yog cov khoom noj tshwj xeeb- qib kraft ntawv. Tsis zoo li cov ntawv tsis muaj zog siv rau cov ntawv sau ntawv lossis cov ntawv xov xwm, cov quav cab - ua cov ntaub ntawv yuav tsum muaj lub zog tensile siab heev - muaj peev xwm tiv thaiv kev tawg lossis ncab thaum rub los ntawm kev siv tshuab loj heev. Cov neeg tsim khoom feem ntau siv cov ntawv muab los ntawm cov hav zoov uas muaj kev tswj hwm ruaj khov, qhov ntev cellulose fibers ntawm cov ntoo zoo li pines thiab firs muab lub cev nruj, muaj zog cov qauv mesh. Txhawm rau tsim cov straw ua haujlwm, cov chaw tsim khoom feem ntau siv cov txheej txheem ntau- txheej txheem, siv cov ntawv sib txawv ntawm cov ntawv hnyav rau ntau qhov chaw ntawm cov quav cab. Cov txheej txheej sab nrauv feem ntau yog cov ntawv sib zog, smoother daim ntawv ua kom zoo rau cov duab nraaj luam ntawv, thaum cov txheej txheem sab hauv muaj hnyav dua, denser kraft ntawv tsim tshwj xeeb kom nqus tau lub cev.
Cov khawv koob uas khi cov ntawv txheej no ua ke yog cov nplaum. Yav dhau los, cov kua nplaum ua lag luam muaj cov tshuaj hluavtaws uas tsis tsim nyog rau zaub mov -cov khoom. Niaj hnub no, straw manufacturing cia siab rau siab heev, dej-resistant, zaub mov- qib adhesives. Cov kua nplaum no feem ntau yog dej-raws li emulsions uas tsis muaj cov organic sib txuas, formaldehydes, thiab cov khoom tsiaj. Cov nplaum yuav tsum kho sai sai hauv qhov cua sov, tsim ib qho kev sib txuas ntawm cov ntawv plies, thiab tiv thaiv kev tawg thaum raug cov kua qaub, dej kub, lossis dej cawv cawv.
Thaum kawg, yog tias cov quav cab muaj cov qauv xim zoo nkauj, lub tuam txhab logo, lossis cov khoom qab zib classic cane stripe, cov khoom noj tshwj xeeb- ua raws cov inks tau qhia. Cov no feem ntau yog soy-raws li lossis dej-raws li pigments uas muaj xoom hnyav hlau lossis cov kuab tshuaj lom. Lawv raug tsim los ua raws li cov ntawv txheej tas mus li yam tsis muaj los ntshav, smudging, los yog leaching xim rau hauv cov dej haus, kom ntseeg tau tias cov neeg siv cov dej haus tseem ntshiab ntawm thawj zaug mus rau qhov kawg.
Cov txheej txheem tsim khoom tseem ceeb: Slitting thiab Multi-Ply Architecture
Thaum cov ntawv nyoos reels, zaub mov-cov nplaum nplaum, thiab eco- cov ntaub ntawv tus phooj ywg tuaj txog ntawm qhov chaw tsim khoom, cov txheej txheem sib dhos tshuab pib. Thawj kauj ruam yog tsom mus rau kev hloov cov ntaub ntawv ntau rau hauv cov khoom muaj meej heev.
Cov ntawv mills xa cov ntawv kraft hauv loj, hnyav yob lub npe hu ua jumbo reels, uas tuaj yeem ntsuas ntau tshaj ib 'meter' dav. Vim hais tias ib tug straw yuav tsum tau tshwj xeeb nyias ribbon ntawm daim ntawv, cov jumbo reels yuav tsum tau muab pub rau hauv siab - ceev precision slitting tshuab. Lub tshuab slitting siv ib tug series ntawm ultra-ntse, ncig riam uas hlais los ntawm cov ntaub ntawv ceev ceev, faib nws mus rau hauv kaum ob ntawm nqaim, nruj lub qhov txhab ribbon spools. Qhov dav ntawm cov hlais ribbon no yuav tsum yog ib feem ntawm ib millimeter; Txawm tias qhov sib txawv me me ntawm qhov dav tuaj yeem ua rau lub tshuab ntim tshuab ntim tshuab tuaj yeem ua rau jam lossis tsim qhov tsis sib xws hauv lub cev straw zaum kawg.
Lub architectural zais cia tom qab ib daim ntawv ruaj khov straw nyob rau hauv nws ntau -ply siv. Txawm hais tias qee qhov pheej yig tshiab straws siv tsuas yog ob txheej ntawm daim ntawv, kev lag luam - qib kev pabcuam zaub mov straws yuav luag thoob plaws ntiaj teb siv peb -ply lossis plaub-ply tsim.
Lub puab ply tsim cov hauv nruab nrab ntawm lub raj, ncaj qha cuam tshuam nrog cov kua rushing. Nws yuav tsum yog cov dej tshwj xeeb- tiv thaiv kom tsis txhob haus dej los ntawm kev nkag mus rau hauv lub plawv ntawm cov quav cab. Qhov nruab nrab ply ua raws li tus txha nqaj qaum, muab cov tuab, hnyav- lub luag haujlwm crush kuj, thiab radial txhav los tiv thaiv cov quav cab los ntawm kev sib tsoo nyob rau hauv lub siab ntawm tib neeg daim di ncauj los yog tuab ice crystals. Sab nrauv ply seals sab nrauv, muab lub qhov ncauj zoo thiab qhov chaw qhuav rau cov neeg siv khoom tuav. Thaum lub sij hawm tsim khoom, peb qhov sib txawv ribbon spools yog ua raws li cov khoom noj khoom haus, tos kom woven ua ke.
The Kauv Winding and Cutting Stage: Shaping the Cylinder
Nrog rau daim ntawv ribbon raug txiav thiab muab tso rau kom zoo, cov tub ntxhais sib dhos tshwm sim nyob rau hauv lub siab - ceev kauv winding tshuab. Lub tshuab no yog lub plawv ntawm tag nrho cov kab ntau lawm, tig tiaj tus strips ntawm daim ntawv mus rau hauv ib qho txuas ntxiv, tsis muaj qhov kawg hollow raj.
Peb daim ntawv ribbons tau kos ib txhij tawm ntawm lawv cov khoom siv sib txuas thiab xa mus rau lub hauv nruab nrab ntawm qhov chaw nres tsheb hlau hu ua mandrel. Lub mandrel txiav txim siab qhov tseeb ntawm txoj kab uas hla ntawm cov quav cab, seb nws puas yog nyias tsib - millimeter cocktail stirrer los yog dav kaum ob - millimeter npuas tshuaj yej straw. Raws li cov ribbons taug kev mus rau lub mandrel, lub puab thiab nruab nrab plies hla los ntawm ib tug automated kua nplaum da dej los yog tshaj ib tug nplaum applicator roller. Lub micro-tswj twj tso kua mis coated daim ntawv txav nrog ib txheej, microscopic txheej zaub mov- qib kua nplaum. Nws yog qhov sib npaug me me: cov nplaum me me dhau los ua rau cov khaubncaws sab nraud povtseg ib nrab ntawm - haus, thaum cov nplaum nplaum ntau dhau saturates daim ntawv pulp, ua rau nws mos thiab tsis muaj zog ua ntej nws txawm tawm hauv lub Hoobkas.
Cov ribbons coated ntaus lub mandrel ntawm ib tug meej, xam kab pheeb ces kaum kaum. Lub luag haujlwm hnyav -, txuas ntxiv roj hmab winding siv qhwv ib ncig ntawm lub mandrel, tuav cov ntawv xa tuaj thiab tig lawv mus rau ntawm qhov nrawm kawg. Vim hais tias cov ribbons tau thov ntawm lub kaum sab xis, lawv cuam tshuam thiab sib tshooj zoo kawg nkaus, tsim ib qho seamless, nruam kauv raj uas nkag mus raws qhov ntev ntawm mandrel zoo li tus nab. Mechanical nro yuav tsum zoo ib yam; Yog tias txoj hlua khi txawm me ntsis, tus qauv kauv yuav cuam tshuam, tsim cov ntsiab lus tsis muaj zog los yog cov seams uas tsis muaj cov kua dej nkag tau yooj yim.
Raws li qhov kawg lub raj ntawm daim ntawv qhov txhab tua tawm ntawm qhov kawg ntawm lub mandrel, nws nkag mus rau hauv lub tshuab txiav txiav. Vim tias lub raj xa mus tsis tu ncua ntawm qhov nrawm tshaj li rau caum metres ib feeb, cov txheej txheem nyob ruaj ruaj tsis tuaj yeem siv. Hloov chaw, lub tshuab siv cov riam phom sib dhos ua ke. Cov txheej txheem no muaj cov txheej txheem ntawm ultra- cov hniav ntse ntse uas txuas rau ntawm txoj kev sib dhos uas txav mus rau qhov sib npaug mus rau cov ntawv ua ntej. Lub taub hau txiav yog qhov nrawm nrawm ntawm daim ntawv txav, snaps kaw kom hlais lub raj kom huv si rau hauv cov qauv lag luam ntev (feem ntau ntawm kaum tsib thiab nees nkaum- plaub centimeters), thiab tom qab ntawd rov pib dua tam sim kom ntes cov ntu tom ntej. Tag nrho cov txheej txheem txiav no tshwm sim nyob rau hauv ib feem ntawm ib millisecond, yielding txhiab tus zoo kawg nkaus txiav straws txhua teev.
Ncej -Kev Tsim Khoom: Kev Kho, Kev Ntsuas, thiab Kev Kho Kom Zoo Tshaj Plaws
Txawm hais tias cov straws tau raug txiav rau lawv qhov loj me, lawv tseem tsis tau npaj kom ntim rau hauv lub thawv. Freshly txiav straws tseem muaj qhov tseem ceeb ntawm cov dej noo los ntawm cov dej- raws li cov khoom noj khoom haus, ua rau lawv me ntsis pliable thiab mos rau qhov kov.
To lock in their ultimate structural strength, the newly formed straws are collected in large trays and transferred into specialized, temperature-controlled curing ovens or drying rooms. Nyob rau ob peb teev, huab cua sov, dehumidified circulates nyob ib ncig ntawm lub straws, maj mam evaporating cov dej seem ntawm cov nplaum matrix. Raws li cov kua nplaum dries, nws crystallizes thiab hardens, fusing peb daim ntawv plies mus rau hauv ib tug ntom, incredibly rigid composite raj. Thaum lub voj voog kho tiav lawm, cov straws nthuav tawm cov khoom ruaj khov, rov ua kom zoo dua thaum flexed, qhia tias lawv tau ua tiav qhov kev ua haujlwm siab tshaj plaws.
Ua ntej mus rau lub tuam tsev ntim khoom, cov khoom siv random los ntawm cov kab ntau lawm tau txais kev tswj xyuas nruj thiab ntsuas kev ntxhov siab. Cov kws kho mob submerge cov qauv straws hauv carbonated, cawv, thiab boiling -kub kua rau lub sij hawm ntev, saib xyuas ntev npaum li cas cov hlab ntsha tuaj yeem tswj tau lawv cov duab ua ntej muag muag. Cov tshuab ntsuas compression siv ntsuas lub cev lub zog rau cov phab ntsa kom ntseeg tau tias cov straws yuav tsis tawg lossis tawg raws li cov neeg siv khoom siv.
Rau cov ntawv thov tshwj xeeb cov khoom noj khoom haus, cov straws qhuav tuaj yeem dhau los ntawm kev siv tshuab ua kom zoo dua ntxiv:
Flexible Straw Processing: Yuav kom tsim tau ib qho "bendy" straw, ncaj kho cov hlab yog pub rau hauv lub tshuab uas compresses ib feem me me ntawm cov ncej tiv thaiv ib tug corrugation tuag, tsim ib tug series ntawm nruj accordion folds uas cia cov straw rau articulation smoothly tsis kinking kaw.
Taw tes-Ntsis Bevelling: Straws destined rau kaw boba teas los yog kua txiv pouches taug kev los ntawm ib tug siab -ceev kab pheeb ces kaum txiav log uas luas ib kawg mus rau hauv ib tug ntse, yam ntxwv taw tes, ua rau tus neeg siv siv zog tho hnyav yas sealing films.
