Qhov chaw ua haujlwm ntawm laminating thermocompression yog nqaim heev, tsuas yog 5-20mm.
Lub sijhawm ua haujlwm ib txwm yog li ntawm {{0}}.1 ~ 0.2s.
Lub lamination ntawm pre-coated zaj duab xis thiab ntawv luam yog ua tiav nyob rau hauv xws li ib tug nqaim ua hauj lwm cheeb tsam thiab nyob rau hauv xws li ib tug luv luv lub sij hawm ua hauj lwm.
Lub sijhawm ua haujlwm, uas yog, kev khiav ceev, txiav txim siab qhov kev txiav txim ntawm cov txheej txheem kev ua haujlwm kub thiab cov txheej txheem hloov pauv ntawm cov nplaum nplaum, qhov zoo thiab qhov tsis zoo ntawm kev ntub dej ntawm cov khoom luam tawm kom ua tiav, thiab tib yam. Lub sij hawm txiav txim siab lub xeev dispersion ntawm cov kub yaj nplaum nplaum thiab lub zog ntawm kev sib txuas.
Hais txog kev hais lus, lub sijhawm ua haujlwm ntev, cov nplaum nplaum kub yaj yog tag nrho melted, qhov saum npoo ntawm cov khoom luam tawm yog tag nrho wetted, thiab nws tsim ib tug dispersive diffusion mus rau lub number case txheej thiab daim ntawv, thiab kev sib txuas ceev ceev.
Ntawm qhov tsis sib xws, lub sijhawm ua haujlwm luv luv, thiab lub teeb T kub yuav muaj peev xwm paub txog qhov hloov pauv hloov pauv hloov pauv ntawm cov nplaum kub yaj raws li qhov kev ncua deb thiab qhov sib lawv liag yav tom ntej, thiab nws tseem tsis tuaj yeem tsim cov molecular dispersion. , infiltration thiab affinity ntawm kub yaj nplaum molecules thiab cov number case txheej thiab ntawv fibers. , ua rau tsis zoo wettability thiab tsis muaj zog adhesion.
Qhov seemingly bonding yog qhov tseeb tsuas yog cov nyhuv ntawm viscosity ntawm cov khoom tackifying thaum qhov kub thiab txias qis dua qhov yuav tsum tau ua haujlwm kub;
Tom qab txias, lub viscosity thiab fluidity thaum lub sij hawm cua sov rov qab mus rau lawv cov qub kub-kub brittleness, thiab lawv tsis tuaj yeem tiv taus qhov cuam tshuam ntawm sab nraud quab yuam thiab cua sov tom qab lamination, ua rau muaj creases los yog hlwv.
Raws li kev ntsuam xyuas ntawm cov nyhuv ntawm compounding pre-txheej zaj duab xis thiab ntau yam ntawv luam tawm nyob rau hauv cov xwm txheej ntawm tib kub, tib lub siab thiab sib txawv ceev hloov, lub pre-txheej zaj duab xis lamination ceev yog standardized raws li nram no:
①Qhov ntau ntawm kev ua haujlwm ceev feem ntau yog 6-12m / min;
② Nyob rau hauv cov ntaub ntawv ntawm lub hauv paus hnyav, siab nruj, siab cov ntsiab lus dej, plua plav, loj number case txheej cheeb tsam, tsaus xim, tsis tshua muaj kev ua hauj lwm ib puag ncig kub, high humidity, ceev roj txaus, tsis zoo brightness ntawm composite khoom, thiab lwm yam. yuav tsum tau txo kom tsim nyog. , qhov twg yog qhov zoo dua rau cov nyhuv sib xyaw;
③ Rau qhov chaw ua haujlwm ntawm 6-12m / min, yog tias qhov nrawm nrawm tau hloov kho hauv qhov nce ntawm 1m / min, qhov nruab nrab ua haujlwm kub yuav poob 3.4 feem pua, thiab kev ua haujlwm siab yuav poob 9.4 feem pua;
④ Hauv thaj chaw ua haujlwm ntawm 12m / min < khiav nrawm Tsawg dua lossis sib npaug li 15m / min, yog tias qhov ntau lawm ceev tau hloov kho hauv qhov nce ntxiv ntawm 1m / min, cov nqi tso tawm ntawm txhua qib sib txawv yuav hloov pauv sai.
