Lub sij hawm ntev, tus "technical stacking method" uas yog ntxiv thiab rho tawm hauv cov txheej txheem ntim printing number case manufacturing thiab ntim printing, thiab cov "intrinsic viscosity method" uas feem ntau yog siv rau hauv kev tsim qauv mis (ntsuas cov nqi ntawm polymer dissolved nyob txawv solubility) Nyob hauv qhov hnyav ntawm cov parameter, cov viscosity intrinsic yog ntsuas ntawm tej yam kev kub, thiab tus qhab nias ntawm qhov siab tshaj plaws intrinsic viscosity yuav txiav txim siab ua tus cev tsis sib haum ntawm lub polymer yog sib npaug rau qhov kev txhuam xyuas qhov muaj nqi ntawm qhov system) thiab qhov "equilibrium swelling method" (ntawm qhov ntsuas kub) Lub crosslinked polymer yog swelled nyob hauv qhov hnyav uas muaj cov tsis txawv txav tsis sib haum, thiab thaum twg qhov sib txig mus, cov qib ntawm o thiab qhov siab tshaj plaws swell yog txiav txim siab, thiab qhov kev ntsuas ntawm lub cev lub cev hnyav sib xyaw yog qhov polymer. Qhov tsis muaj teeb meem), qhov no yog ob txoj kev yooj yim thiab intuitive txoj kev txiav txim siab txog kev tsis sib haum xeeb ntawm polymer tebchaw, thiab yog deb ntawm qhov uas yuav tsum ua kom tau raws li niaj hnub ntim thiab tshuab luam ntawv.
Cov "ob-dimensional number case making method" uas tau piav qhia no yog ua raws li txoj ntsiab cai uas lub cev tsis sib xws yog zoo ib yam lossis zoo sib xws thiab yuav tsum muaj kev sib tov sib txawv, los txiav txim siab seb puas yog cov kab tho los yog ua kom hnyav thiab sib txuam sib luag tus number case thiab lub substrate.
Qhov thib ob yog twv lub miscibility ntawm ob lub kuab tshuaj los yog hauv qab nrog substrate raws li lub hauv paus ntsiab lus tias qhov kev ntsuas qhov tseem ceeb yog qhov sib npaug lossis zoo sib xws thiab tuaj yeem sib hloov tau.
Qhov thib peb yog raws li qhov kev ntsuas hauv lub cev, nws yuav raug kwv yees tias cov kev sib txuam sib luag ntawm ob los sis ntau lub cev (tus cias tsis tuaj yeem yuav ntau dua 1.5 saum toj saud thiab qis tshaj) thiab qhov adherion ntawm substrate.
Qhov thib plaub yog siv cov resin nyob rau hauv lub hnab ntim printing number case nyob rau hauv cov xuabmoos uas tsis paub txog kev paub daws teebmeem, thiab qhov ntau ntawm cov kabmob solubility tsis txog cov duab thiab lub substrate tuaj yeem txiav txim siab.
Raws li qhov kev ntsuas lub cev, peb tuaj yeem txiav txim rau qhov hnyav xaj ntawm cov cuav pliav tom qab luam ntawv.
Raws li tus qauv ntawm tus cwj mem kua xaim, lub sib txuas ntawm hydrogen thiab qhov taw tes softening yog yaj, thiab qhov adhesion, yooj, hnav ua haujlwm thiab tshav kub tsis zoo ntawm cov ntawv luam tawm tom qab cov zaj duab xis tag nrho yuav raug kwv yees.
Raws li cov tsis muaj kev sib raug zoo ntawm hydrogen tsev quab yuam, nws tau xaiv qhov tsim nyog thiab pheej yig ream thiab hnyav hauv txheej txheem ntawm ntim thiab luam ntawv number case, thiaj li tswj cov khoom nqi ntawm ntim luam ntawv number case.
Txawm li cas los xij, ob los sis ntau dua cov tshuaj los yog xyaw cov xo tshuaj muaj feem ntau siv rau hauv cov ntawv ntim khoom muag. Txoj kev muab xam yuav tsum tswj nws txoj kev sib haum xeeb ntawm cov dej tawg thiab qhov chaw nrhoo thiab qhov tsis muaj zog txaus kom tau qhov tseeb (piv txwv li, tsis yog-sib thooj) viscosity ntawm cov kua sib xyaw kom ua tau zoo thiab cov nqi qis khoom - solvent thiab resin solubility. Thiab qhov sib txuas ntawm hydrogen ntawm tus cwj pwm kua mis thiab lub substrate (raug xa mus rau kev sib haum xeeb ua hluav taws xob).
Lus Cim: Qhov sib xyaw xyaw ua rau lub cev tsis tshua muaj zog vim qhov sib lawv liam thiab qis dua, thiab lub qis dej ntau dua sai dua ib qho kev hnyav. Nyob rau tib lub sij hawm, muaj kev sib sib zog nqus los ntawm hydrogen nyiaj quab yuam tau thaum lub cua sov txheej txheem ntawm tus cwj pwm zaj duab xis, thiab cov pinhole ntawm tus cwj pwm zaj duab xis tiv thaiv tau. , ntsws qhov thiab xuas ntswj.
Ntawm qhov txhais tes, raws li txoj ntsiab cai ntawm solvation, qhov o thiab dissolution ntawm lub siab polymer muaj feem xyuam rau lub solvation / uas yog, thaum lub siab molecular polymer thiab qhov hnyav feem ntau tiv tauj, kev sib txuas ntawm cov hnyav molecules nrog polymer molecules Qhov kev quab yuam no yog ntau tshaj qhov sib sib zog nqus ntawm qhov sib xyaw ntawm cov molecules ntawm lub polymer, kom cov polymer molecules thiaj tau sib cais los ntawm cov leeg thiab yaj nyob hauv qhov hnyav. Lub attraction ntawm hnyav ncov qaumteb qabteb molecules thiab cov polar pawg ntawm cov polymer yuav ua rau solvation dissolve polymer. Nws yog zoo paub tias cov nyhuv no feem ntau tsuas yog txhais raws li: ib qho tshuaj acidic tau yaj ib theem pib polymer, txwv tsis pub nws yog qhov ntxeev lus. Nws yog feem ntau txhais nyob rau hauv txoj kev xav tias ib tug electron acceptor tau dissolve ib tug electron pub.
Qhov hnyav evaporates ntawm tus cwj pwm zaj duab xis thiab qhuav, uas yog hu ua tus nqi evaporation. Txawm hais tias nws tau raug pom tias lub ntsiab lus ntawm qhov hnyav yuav siv los ua lub hauv paus rau kev twv nws cov volatility, tsuas yog txoj cai no tau ntsib ntawm homologues los yog roj solvents. Yog li ntawd, nws yog qhov tseem tsis zoo li ib txoj kev dav, thiab nws yog qhov tsis tseeb. Ib qho ntawm lub ntsiab lus tseem ceeb yog qhov ua tau ntawm hydrogen tsev. Piv txwv, lub hau chiv ntawm ethanol thiab benzene yog nyob ze, thaum lub evaporation tus nqi ntawm benzene yog ob zaug ntawm ethanol. Lub hau chiv ntawm butanol yog qis tshaj qhov ntawm n-butyl acetate, thiab cov volatilization tus nqi tseem tsawg. Hydrogen bonding plays lub luag haujlwm tseem ceeb hauv kev lim dej evaporation ntawm tus cwj pwm zaj duab xis ntawm hnyav raws li luam ntawv hauv qab.
Qhov tseeb, qhov kub thiab txias, qhov chaw ntim zaj duab xis, qhov tob hauv lub cwj mem qhuav ntawm lub polymer, thiab qhov ntau ntawm qhov chaw nro tag nrho ncaj qha rau kev zij ziab ntawm tus cwj mem naj npawb ntawm cov hnab yas luam ntawv, tshwj xeeb tshaj yog cov kab xev ua kom zoo tom qab ua luam ntawv (kho).
