Cov kab lus no tsuas yog xaiv MMA, Npa, Aa ua monomers, thiab cov kev ntsuas kub ntxiv, thiab pom cov txheej txheem vaj huam sib luag zoo tshaj plaws. Cov roj hmab yog thawj masticated, tom qab ntawd stirred thiab yaj thiab yaj thiab muab cov kuab tshuaj sib xyaw ntawm 70 ° C, thiab tom qab ntawd tus pib BPO ntxiv rau hauv cov pob. Thawj Monomer MMA yaj nrog BOP yog ntxiv ntawm 80 ~ 90 feeb, ntxiv rau tus monomer thib peb ntawm 84 ~ 88 ℃ thiab do rau 45 feeb, khaws cia Sov rau 1.5 ~ 2 teev, tom qab ntawd tau CR / MMA-BA-A-txoj kev muaj zog loj dua CR / MMA-BA, nws tus nqi yog 6.6 Kn.m-1.
Ntsiab lus: Neoprene nplaum nplaum, Txhuam nplaum, Ntau hom grafere nplaum.
Cellulose etherMCthiabHPMCMuaj cov kev ua tiav zoo, emulsification, thickening, zaj duab xis, ua yeeb yaj kiab ua si, thiab tseem muaj cov kev ua dej txig, thiab kev sib cais ntawm cov kuab tshuaj organic.
Cov khoom tseem ceeb tam sim no tsim yog RT Series MC thiab HPMC ntau yam, uas nws qib kawm), 605rt (hydroxyprropencellulose), 75rt rau cov qib ntawm lub tuam txhab quav tshuaj yog methocel a, e, F thiab K, ntsig txog.
RT series khoom yog heev pab txhawb cov khoom siv hauv tsev vim lawv cohesiveness, tshem tawm ruaj khov thiab dej ceev. Piv txwv li, lawv tuaj yeem tsim rau hauv cov xim zoo "phab ntsa thiab cov hmoov av nplaum, uas tau siv nyob rau hauv chaw nres tsheb nkoj Ib qho ntxiv, nws tuaj yeem siv los ua cov electrolyte hauv electrolytic capacitors thiab ib qho muaju hluav taws xob, thiab ua kom tuab rau cov dej emulsions hauv cov xim tha xim. Nyob rau hauv looj xim thiab dej-soluble pleev xim, nws tuaj yeem siv ua zaj duab xis, thickener, emulsifier, dej rov qab qhwv roj hmab hmoov, thiab lwm yam.
Cov lus tseem ceeb: MEthyl cellulose, hydroxy profurose cellulose, adhesive, ntawv thov.
Kev Loj Hlob Cov Dej-Raws Li Cov Ntawv Yas Yas Ntxuav
Nyob rau hauv xyoo tsis ntev los no, tus txheej txheem tshiab ntawm pasting yas zaj duab xis ntawm cov luam ntawv tau tsim. Nws yog BOPP (Biaxial Oriented Polypropylene zaj duab xis) coated nrog cov nplaum thiab tom qab ntawd kev nias lub tog raj kheej thiab cov menyuam cua sov los ua ib daim ntawv. / Yas 3-hauv-1 luam tawm. Qhov no cuam tshuam nrog cov teeb meem ntawm daim ntawv thiab cov yas sib raug zoo. BOPP yog cov khoom tsis-polar, yog li ntawd, muaj qhov xav tau ntawm cov nplaum uas muaj cov nplaum zoo rau ob qho tib si polar thiab cov khoom tsis muaj nyiaj polar.
Nws ob sab shesive nrog epoxy cob muaj tau zoo sib xws. SBS yog elastomer viscose. Nws tuaj yeem pom los ntawm nws qhov kev nkhaus pov tseg uas thiaj li ua kom pom zoo rau cov nplaum nplaum ua rau lub viscose, nws yuav tsum tau tswj hwm ib ncig ntawm SBS: Epoxy Resin = 2: 1. Los ntawm tev lub zog nkhaus, nws tuaj yeem pom tau tias thaum qhov sib piv yog siab, lub zog tev yuav zoo, tab sis cov nplaum yuav nce ntxiv. Txhawm rau kom tsis txhob muaj ada, SBS: Epoxy Resin = 1: 1 ~ 2.5: 1 tuaj yeem tswj tau kom tau txais lub zog ua kom muaj zog. Xav txog kev nkag siab, txiav txim siab SBS nyob rau hauv lub ntsiab kua nplaum: Epoxy Resin = 1: 1 ~ 3.5: 1.
Lub luag haujlwm tseem ceeb ntawm kev siv cov ntawv pov tseg khi yog txhawm rau txhawm rau txhawm rau lub zog ntawm lub matrix thiab txhim kho lub wettability ntawm cov kua nplaum ntawm cov kua nplaum thiab cov khoom sib txawv. Tus txheej txheem txiav Los ntawm ntau qhov kev ntsuam xyuas, nws tau xaus lus tias feem pua ntawm kev tso tawm Rosin hauv cov kua nplaum yog 1.59n / 25mm (ntawv-yas).
Tus nqi ntawm kev sib txuas tau muaj qee yam cuam tshuam ntawm cov khoom nplaum. Qhov zoo tshaj plaws yog thaum qhov sib piv ntawm cov kua nplaum tseem ceeb thiab sib khi yog 1: 1. Tev lub zog n / hli yas-yas 1.4, ntawv-yas 1.6.
Hauv txoj kev tshawb no, MMA tau siv raws li kev ua rau lub zog kom sib xyaw SBS thiab MMA. Kev sim tau pom tias kev siv MMA tsis tuaj yeem ua tiav lub hom phiaj ntawm kneading cov khoom siv hauv colloid, tab sis kuj txo cov viscosity thiab txhim kho cov khoom nplaum. Yog li ntawd, MMA yog qhov haum tau hloov kho. Tom qab kev sim, qhov nyiaj ntawm MMA siv yog tag nrho cov kua nplaum 5% ~ 10% yog qhov tsim nyog.
Txij thaum cov qauv tsim viscose yuav tsum yog dej-soluble, peb xaiv cov xim dawb (polyvinyl acetate emulsion) raws li dej-soluble cabrier. Tus nqi ntawm cov lej dawb latex rau 60% ntawm tag nrho cov viscose. Tom qab cov dej-based viscose yog emulsified lub xeev los ntawm kev dispersion thiab emulsified carrier, yog tias nws diluted li cas yog tsis haum rau kev siv, nws tuaj yeem ua rau dej. Txoj kev ua haujlwm no yog ob qho tsawg tus nqi thiab tsis muaj tshuaj lom (tsis tas siv cov tshuaj lom neeg), thiab cov dej zoo tshaj plaws yog 10% ~ 20%.
Txhawm rau tshem tawm cov seem ntawm Viscose, nws tau sim uas dilute na2co3 tov yog siv los ua tus neeg sawv cev alkalizing, thiab cov nyhuv yog qhov zoo tshaj plaws. Qhov kev xav ntawm cov nyhuv ntawm tus neeg sawv cev alkalizing yuav yog saponification cov tshuaj tiv thaiv qhia tau qee cov ntsev uas tsis muaj zog los hloov rau hauv soluble ntsev. Ib qho ntxiv, yog tias muaj zog ntau dua rau cov kua nplaum, lub zog nplaum yuav ploj, yog li cov kua nplaum tsis haum rau ib puag ncig alkaline.
Cov txheej txheem tsim nyog.
