Qhov ntev ntawm tus nqi yog siab dua nyob rau hauv ob qho tib si, los ntawm kwv yees li ib lub hlis twg.
Tsis muaj dab tsi hauv daim ntawv piav qhia vim li cas. Cov lus teb yog tias daim ntawv tsis zoo ib yam nyob rau hauv txhua qhov kev coj, thiab yog vim li cas nws tsis yog qhov uas nws tau ua.
Ib daim ntawv muaj cov nplej, thiab tsis muaj leej twg qhia koj tias nws khiav mus rau qhov twg
Polymer chains ua ke ib nrab ntawm cov khoom siv tau ncab thaum tsim, thiab lawv nyob li ntawd. Qhov tshwm sim yog ib daim ntawv uas ntsuas muaj zog raws nws qhov ntev tshaj li hla nws qhov dav. Cov ntaub ntawv qhia nws ncaj ncees nyob rau hauv ob kab thiab tom qab ntawd tawm ntawm tus nyeem ntawv los ua kom paub tias nws txhais li cas.
II. Dab tsi Rolls Ua rau Melt
Calendering yog qhov qub ntawm ob txoj kev thiab ib qho uas tib neeg feem ntau tsis tau hnov txog, txawm tias tau siv nws cov khoom tso tawm txhua hnub.
Cov yaj yog pub rau hauv ib pawg ntawm rhuab steel yob. Txhua qhov sib txawv ua tiav tau teeb tsa me ntsis nqaim dua li qhov kawg, nyem cov khoom mus rau qhov tswj cov tuab. Cov yob yog hauv av mus rau ib tug zoo kam rau ua thiab polished, thiab lawv tiav hloov mus rau daim ntawv.
Peb yuav tshwm sim los ntawm qhov kev npaj ntawd.
| Yam ntxwv | Yog vim li cas nws raws li los ntawm rolls |
|---|---|
| nruj heev thickness tswj | Lub steel yob qhov sib txawv yog qhov precision dimension. Tsis muaj dab tsi ntxiv hauv daim ntawv sib sau tswj cov tuab raws li ncaj qha. |
| Zoo heev nto finish | polished yob lub ntsej muag yog pauv mus rau daim ntawv, uas yog vim li cas calendered khoom yuav glossy los yog matte ntawm kev thov. |
| Cov khoom nyias nyias | Rolls tsuas yog qhib kom deb li deb ua ntej lub nip nres coj tus cwj pwm zoo, uas ua rau lub ntsej muag tuab |
| Tshuab -kev taw qhia kev taw qhia | Lub nyem ntawm yob stretches lub yaj raws cov kev taw qhia ntawm kev mus los thiab aligns chains raws li nws mus |
Tus nqi peev yog siab thiab cov khoom siv tau loj, uas yog vim li cas calendering dominates qhov twg loj ntim ntawm cov khoom nyias xav tau. Pem teb hnav khaubncaws sab nraud povtseg, phab ntsa npog, zaj duab xis thiab nyias nruj daim ntawv yog tag nrho cov natural calendered khoom.
Foaming tsis yog ntawm lawv. Ib daim ntawv foamed xav tau lub siab poob thaum lub sijhawm tsim kom cov pa yaj tuaj yeem tawm ntawm kev daws thiab nthuav, thiab yob nip tsis muab qhov ntawd.
III. Qhov Tuag Ua Dab Tsi
Extrusion thawb lub yaj los ntawm qhov qhib qhov zoo li tsis txhob nyem nws ntawm yob, thiab qhov sib txawv ntawm qhov uas tso cai yog qhov tseem ceeb.
Lub tuag teem ib tug ntoo khaub lig seem. Haul-tawm yob tom qab ntawd kos cov ntawv tawm sai dua li nws tawm hauv qhov tuag, uas nws thins nws ntxiv los ntawm tus nqi tswj. Thickness yog li cov khoom ntawm ob qhov sib txawv es tsis yog ib qho kev ruaj khov, thiab qhov ntawd ua rau nws nyuaj rau tuav qhov tseeb.
Dab tsi extrusion yuav rov qab yog ntau yam. Ib qho kev tuag ib leeg tuaj yeem tsim cov khoom los ntawm ib daim ntawv nyias mus txog rau lub rooj tsavxwm tuab los ntawm kev kho qhov sib piv, thiab cov txheej txheem tso cai rau lub siab poob siab uas foaming xav tau. Yuav luag txhua lub rooj tsavxwm PVC ua npuas ncauj ntawm kev ua lag luam los ntawm txoj kab extrusion vim li ntawd.
Ob qhov chaw ntawm kev taw qhia, tsis yog ib qho
Ntws los ntawm cov tuag aligns chains raws li cov yaj yog compressed thiab zoo li tus, thiab kos-down nruab nrab ntawm lub tuag thiab lub haul- tawm aligns lawv dua li daim ntawv yog stretched. Ob qhov cuam tshuam pawg, uas yog vim li cas cov ntawv extruded feem ntau qhia qhov sib txawv loj dua li cov khoom siv calendered ntawm qhov sib piv thickness.
Cov kab teeb tsa uas tswj hwm txhua qhov no tau hais meej meej hauv peb qhov kev tawg ntawmcov extrusion variables qab PVC ua npuas ncauj board. Qhov tseem ceeb ntawm no yog qhov kev xaiv ntawm txoj kev, tsis yog kev kho ntawm nws.
IV. Qhov twg ob txheej txheem sib tshooj
Muaj ib pawg tuab tuab qhov twg ob txoj kev tuaj yeem tsim tau ib daim ntawv muag. Cov pab pawg ntawd yog qhov chaw hloov pauv kev pheej hmoo nyob.
