Thaum sov li chav tsev, nws yog cov hmoov dawb los yog cov siv lead ua flaky, soluble hauv dej thiab cov kuab tshuaj organic xws li formaldehyde, ethanol, acetone, tetrahydrofuran, ethyl acetate, acrylonitrile, styrene, thiab lwm yam. Cov khoom no yooj yim heev rau kev tsim cov polymer los ntawm kev sib xyaw nrog ntau yam monomer thiab ua tiav kev nqus dej zoo, tab sis nws tsis yaj hauv ethane, roj av ether.
DAAM muaj ob pawg tshuaj tiv thaiv, uas yog N - hloov amides thiab ketone, nws yooj yim heev rau kev sib xyaw nrog lwm cov vinyl monomer, yog li kev qhia txog ketone carbonyl tshuaj lom neeg tuaj yeem ua rau polymer mus rau crosslinking thiab graft reaction, uas tuaj yeem npaj ntau yam nplaum, thickener, ntawv txhawb nqa tus neeg sawv cev, crosslinking tus neeg sawv cev, thiab lwm yam.
Nws tau siv dav hauv cov teb xws li cov tshuaj pleev xim, cov nplaum, kev lag luam tshuaj txhua hnub, cov neeg sawv cev epoxy resin curing, cov tshuaj ntxiv rau cov tshuaj photosensitive, cov khoom siv textile, kev kho mob, thiab lwm yam.
1. Tus neeg saib xyuas plaub hau:
Ib qho tseem ceeb ntawm DAAM yog tias nws cov homopolymer lossis copolymer tsis yaj hauv dej, tab sis lawv cov dej nqus tau tuaj yeem ncav cuag 20% ~ 30% ntawm nws qhov hnyav, thaum qhov chaw ib puag ncig noo tsawg dua 60%, lawv tuaj yeem tso cov dej noo tawm, tom qab ntawd cov tshuaj tsuag plaub hau tuaj yeem tsim los ntawm cov yam ntxwv zoo li no.
2. Cov roj hmab uas rhiab heev:
Cov tshuaj photosensitive resin uas tsim los ntawm lub teeb, tawv, kua qaub thiab alkali-resistant khoom diamine homopolymer muaj qhov ceev ceev ntawm kev thaij duab resin, qhov tsis cuam tshuam yooj yim tshem tawm tom qab raug, yog li tau txais daim ntawv meej nrog lub zog zoo thiab tiv taus dej.
Lwm daim ntawv thov tseem ceeb ntawm DAAM yog tias nws tuaj yeem hloov qee qhov gelatin, uas yog siv rau cov duab emulsions thiab nyuaj rau hloov los ntawm lwm cov khoom zoo tagnrho. Gelatin tau ntev lawm tsis muaj txaus rau kev ntshiab siab ntawm cov duab, 2500 tons ntawm gelatin xav tau rau cov ntaub ntawv photosensitive, thaum cov duab gelatin tsim tawm hauv tsev tsuas yog ntau pua tons xwb tam sim no.
3. Siv rau kev npaj cov ntawv yas luam tawm
4. Siv rau cov nplaum:
siv ua cov nplaum txhawb nqa thiab txhim kho rau cov tshuaj fiber, cement, iav, txhuas thiab PVC, lub sijhawm no nws kuj tseem tuaj yeem raug nias kom tsim cov nplaum siab, thiab tuaj yeem siv ua cov nplaum kub rau ntawv, textiles thiab yas zaj duab xis nrog allyl polymer.
5. Daim ntawv thov hauv lwm yam:
⑴ siv tau ua tus neeg sawv cev rau epoxy resin, xim tiv thaiv xeb ntawm lub nkoj hauv qab, xim hauv qab dej ntawm lub nkoj hauv qab, acrylic resin coatings, unsaturated polyester xim, thiab lwm yam;
⑵ Cov dej-soluble copolymer monomer ntawm DAAM tau siv tau zoo rau kev ua kom pom tseeb ntawm cov khoom khov kho;
⑶ Siv tau ua cov ntaub ntawv sau cia laser uas tsim los ntawm cua sov;
⑷ Siv ua cov tshuaj ntxuav iav uas tsis pom tseeb;
⑸ Siv ua cov khoom sib xyaw ua ke ntawm cov dej-soluble photosensitive resin;
⑹ Siv rau cov xim pleev dej uas yaj tau.
