Heerkulka qolka, waa budo cad ama kiristaalo jilicsan, oo ku milma biyaha iyo dareerayaasha organic sida formaldehyde, ethanol, acetone, tetrahydrofuran, ethyl acetate, acrylonitrile, styrene, iwm. Alaabtu aad bay u fududahay in lagu sameeyo polymer by copolymerization leh monomer kala duwan oo lagu gaaro nuugista biyaha xooggan, laakiin waa mid aan milmi karin ethane, ether petroleum.
DAAM waxay leedahay laba kooxood oo falcelin ah, oo kala ah N - amides la beddelay iyo ketone, aad bay ugu fududahay copolymerization monomer kale oo vinyl ah, sidaas darteed soo-bandhigidda guryaha ketone carbonyl ee kiimikada waxay u horseedi kartaa polymer-ka isku-tallaabta iyo falcelinta tallaalka, kaas oo diyaarin kara xabagyo kala duwan, dhumuc, wakiilka waraaqaha xoojinta, wakiilka iskutallaabta, iwm.
Waxaa si weyn loogu isticmaalay meelaha sida daahan, xabagta, warshadaha kiimikaad maalinlaha ah, wakiilka daawaynta resin epoxy, wax lagu daro resin photosensitive, caawiye dharka, daryeelka caafimaadka, ect.
1. Wakiilka daryeelka timaha:
Mid ka mid ah astaamaha muhiimka ah ee DAAM ayaa ah in homopolymer-ka ama copolymer-ka aysan ku milmi karin biyaha, laakiin heerka nuugista biyuhu wuxuu gaari karaa 20% ~ 30% miisaankiisa, marka qoyaanka deegaanka uu ka yar yahay 60%, waxay xitaa sii deyn karaan qoyaanka, ka dibna buufinta timaha waxaa lagu soo saari karaa iyada oo la adeegsanayo sifada noocaas ah.
2. Xabagta xasaasiga ah:
Xajiinta sawir-qaadista ee ay soo saarto nalka, adag, acid iyo alkali-u adkeysiga adag diamine homopolymer wuxuu leeyahay xawaare sare oo sawir qaadis ah, qaybta aan saameynin way fududahay in la saaro ka dib soo-gaadhista, sidaas darteed helitaanka qaab warqad cad oo leh xoog wanaagsan iyo caabbinta biyaha.
Codsiga kale ee muhiimka ah ee DAAM waa in ay qayb ahaan bedeli karto jelatin, taas oo loo isticmaalo emulsions sawir leh oo ay adag tahay in lagu beddelo alaabada kale ee ku habboon. Gelatin ayaa muddo dheer ka maqnaa sahayda nadiifinta sare ee sawir-qaadista, 2500 tan oo jelatin ah ayaa la filayaa in loo isticmaalo qalabka sawir-qaadista, halka wax-soo-saarka jelatin-ka-guud ee gudaha uu hadda yahay boqollaal tan.
3. Waxaa loo isticmaalaa diyaarinta daabacaadda warqadda caagga ah
4. Loo isticmaalo xabagta:
loo isticmaalo kor u qaadida xabagta iyo hagaajinta xeryahooda fiber-ka, sibidhka, galaaska, aluminium iyo PVC, Dhanka kale waxa kale oo lagu cadaadin karaa si loo soo saaro xabagta cadaadiska-xasaasi ah, oo loo isticmaali karaa sida xabagta-xasaasi ah warqad, dhar iyo filim caag ah oo leh allyl polymer. .
5. Codsiga dhinacyada kale:
⑴ waxaa loo isticmaali karaa sida wakiilka daawoyinka ee xabagta epoxy, rinjiga anticorrosive ee markabka hoose, rinjiga biyaha hoostooda ee hoose ee markabka, daahan resin acrylic, rinjiga polyesterka unsaturated, iwm;
⑵ monomer-ka koobiyeerka biyaha ku milma ee DAAM ayaa si wax ku ool ah loogu dabaqay caddaynta adkaha la hakiyey;
⑶ Waxaa loo isticmaali karaa sida qalabka wax lagu duubo laysarka ee uu soo saaro kulaylka;
⑷ Waxaa loo istcimaalaa sidii dhalo ka saarid dawakhsan;
⑸ Waxa loo istcimaalaa sida ka kooban xabagta sawir-qaadista ee biyaha-milmi karta;
⑹ Waxaa loo isticmaalaa rinjiga biyaha ku milma.
