Pa kutentha, ndi ufa woyera kapena kristalo wonyezimira, wosungunuka m'madzi ndi zosungunulira organic monga formaldehyde, ethanol, acetone, tetrahydrofuran, ethyl acetate, acrylonitrile, styrene, etc. Chogulitsacho ndi chosavuta kwambiri kupanga polima ndi copolymerization ndi monomer osiyanasiyana ndikukwaniritsa kuyamwa kwamadzi mwamphamvu, koma sikusungunuka mu ethane, petroleum ether.
DAAM ali ndi magulu awiri zotakataka, ndicho N - m'malo amides ndi ketone, n'zosavuta kwambiri kuti copolymerization ndi vinilu monoma, motero kumayambiriro ketone carbonyl mankhwala katundu kungachititse polima kuti crosslinking ndi kumezanitsa anachita, amene angathe kukonzekera zomatira zosiyanasiyana, thickener, pepala reinforcing wothandizira, crosslinking wothandizira, etc.
Zakhala zikugwiritsidwa ntchito kwambiri m'magawo monga zokutira, zomatira, makampani opanga mankhwala tsiku lililonse, epoxy resin kuchiritsa wothandizila, photosensitive resin zowonjezera, nsalu zothandizira, chisamaliro chaumoyo, ect.
1. Wosamalira tsitsi:
Chikhalidwe chimodzi chofunikira cha DAAM ndikuti homopolymer yake kapena copolymer sichisungunuka m'madzi, koma kuchuluka kwa mayamwidwe amadzi kumatha kufika 20% ~ 30% ya kulemera kwake, pomwe chinyezi cha chilengedwe chimakhala chochepera 60%, amatha kumasula chinyezi, ndiye tsitsi lopopera likhoza kupangidwa ndi chikhalidwe choterocho.
2. Photosensitive resin:
Photosensitive utomoni wopangidwa ndi kuwala, zolimba, asidi ndi alkali- kugonjetsedwa olimba diamine homopolymer ali mkulu utomoni zithunzi liwiro, mbali zosakhudzidwa n'zosavuta kuchotsedwa pambuyo kukhudzana, motero kupeza bwino pepala masanjidwe ndi mphamvu zabwino ndi kukana madzi.
Ntchito ina yofunika kwambiri ya DAAM ndikuti imatha kulowa m'malo mwa gelatin, yomwe imagwiritsidwa ntchito ngati emulsion yojambula komanso yovuta kusinthidwa ndi zinthu zina zabwino. Gelatin yakhala ikusoweka kwa nthawi yayitali kuti ikhale yoyera kwambiri, matani 2500 a gelatin amayembekezeredwa kuti apange zinthu zowoneka bwino, pomwe kujambula kwapanyumba kwa gelatin kumangokhala matani mazana ambiri pakadali pano.
3. Ntchito yokonza pulasitiki letterpress kusindikiza
4. Ntchito zomatira:
ntchito monga zomatira kulimbikitsa ndi improver kwa CHIKWANGWANI mankhwala, simenti, galasi, aluminiyamu ndi PVC, panthawiyi akhoza wothinikizidwa kupanga zomatira kuthamanga-tcheru, ndipo angagwiritsidwe ntchito ngati zomatira kutentha tcheru kwa pepala, nsalu ndi filimu pulasitiki ndi allyl polima. .
5. Kugwiritsa ntchito mbali zina:
⑴ itha kugwiritsidwa ntchito ngati mankhwala ochizira utomoni wa epoxy, utoto wothirira pansi pa sitimayo, utoto wapansi pamadzi pansi pamadzi, zokutira za acrylic resin, utoto wa poliyesitala wopanda unsaturated, ndi zina zambiri;
⑵ Copolymer monomer yosungunuka m'madzi ya DAAM idagwiritsidwa ntchito bwino pakuwunikira kolimba koyimitsidwa;
⑶ Itha kugwiritsidwa ntchito ngati zida zojambulira laser zopangidwa ndi kutentha;
⑷ Amagwiritsidwa ntchito ngati chochotsera magalasi osawoneka bwino;
⑸ Amagwiritsidwa ntchito ngati utomoni wosungunuka m'madzi;
⑹ Amagwiritsidwa ntchito popanga utoto wosungunuka m'madzi.
