Pa kutentha kwa chipinda, ndi ufa woyera kapena kristalo wosweka, wosungunuka m'madzi ndi zinthu zina monga formaldehyde, ethanol, acetone, tetrahydrofuran, ethyl acetate, acrylonitrile, styrene, ndi zina zotero. Chogulitsachi n'chosavuta kwambiri kupanga polima pogwiritsa ntchito copolymerization ndi monomer zosiyanasiyana ndipo chimapeza madzi amphamvu, koma sichisungunuka mu ethane, petroleum ether.
DAAM ili ndi magulu awiri okhudzidwa, omwe ndi N - substituted amides ndi ketone, ndi yosavuta kwambiri kupanga copolymerization ndi vinyl monomer ina, motero kuyambitsa ketone carbonyl chemical properties kungayambitse polymer ku crosslinking ndi graft reaction, yomwe imatha kukonzekera zomatira zosiyanasiyana, thickener, paper reinforcement agent, crosslinking agent, ndi zina zotero.
Yagwiritsidwa ntchito kwambiri m'magawo monga zokutira, zomatira, makampani opanga mankhwala a tsiku ndi tsiku, epoxy resin curing agent, zowonjezera za resin zomwe zimakhala ndi kuwala, zothandizira nsalu, chisamaliro chaumoyo, ndi zina zotero.
1. Wosamalira tsitsi:
Khalidwe limodzi lofunika la DAAM ndilakuti homopolymer kapena copolymer yake sizisungunuka m'madzi, koma kuchuluka kwa madzi omwe amayamwa kumatha kufika 20% mpaka 30% ya kulemera kwake, pamene chinyezi cha chilengedwe chili chochepera 60%, amatha kutulutsa chinyezi, kenako kupopera tsitsi kumatha kupangidwa pogwiritsa ntchito mawonekedwe otere.
2. Utomoni wofewa ndi kuwala:
Utomoni wofewa ndi kuwala womwe umapangidwa ndi homopolymer yolimba, yolimba, ya asidi komanso yolimba ya diamine yokhala ndi mphamvu ya alkali imakhala ndi liwiro lalikulu la kujambula zithunzi, gawo losakhudzidwalo ndi losavuta kuchotsa mutalowa, motero limakhala ndi pepala lomveka bwino komanso lolimba komanso lolimba ku madzi.
Ntchito ina yofunika kwambiri ya DAAM ndi yakuti imatha kusintha pang'ono gelatin, yomwe imagwiritsidwa ntchito popanga zithunzi ndipo ndi yovuta kuisintha ndi zinthu zina zabwino. Gelatin yakhala ikusowa kwa nthawi yayitali chifukwa cha kuyera kwambiri kwa zithunzi, matani 2500 a gelatin akuyembekezeka kugwiritsidwa ntchito pazinthu zomwe zimakhudzidwa ndi kuwala, pomwe kupanga gelatin yojambulidwa m'nyumba ndi matani mazana okha pakadali pano.
3. Amagwiritsidwa ntchito pokonza zosindikizira za pulasitiki
4. Yogwiritsidwa ntchito pa zomatira:
imagwiritsidwa ntchito ngati cholimbikitsira zomatira komanso chowonjezera zinthu zopangidwa ndi ulusi, simenti, galasi, aluminiyamu ndi PVC, pakadali pano imatha kupanikizika kuti ipange zomatira zomwe zimakhudzidwa ndi kupanikizika, ndipo ingagwiritsidwe ntchito ngati zomatira zomwe zimakhudzidwa ndi kutentha kwa mapepala, nsalu ndi filimu ya pulasitiki yokhala ndi allyl polymer.
5. Kugwiritsa ntchito mbali zina:
⑴ ingagwiritsidwe ntchito ngati chothandizira kuchiritsa utomoni wa epoxy, utoto woletsa kuwononga pansi pa sitima, utoto wa m'madzi wa pansi pa sitima, zokutira za utomoni wa acrylic, utoto wa polyester wosakhuta, ndi zina zotero;
⑵ Copolymer monomer yosungunuka m'madzi ya DAAM idagwiritsidwa ntchito bwino powunikira cholimba chopachikidwa;
⑶ Ingagwiritsidwe ntchito ngati zipangizo zojambulira za laser zopangidwa ndi kutentha;
⑷ Amagwiritsidwa ntchito ngati chochotsera fumbi lagalasi;
⑸ Amagwiritsidwa ntchito ngati kapangidwe ka utomoni wosungunuka m'madzi womwe umatha kusungunuka ndi kuwala;
⑹ Amagwiritsidwa ntchito popanga utoto wosungunuka m'madzi.
