Mu bushyuhe bw'icyumba, ni ifu yera cyangwa kristu ishaje, ishongeshwa mu mazi no mu bintu bishongesha nk'ibikomoka ku bimera nka formaldehyde, ethanol, acetone, tetrahydrofuran, ethyl acetate, acrylonitrile, styrene, nibindi. Iki gicuruzwa cyoroshye cyane gukora polymer hakoreshejwe copolymerization hamwe na monomer zitandukanye kandi kigera ku mazi menshi, ariko ntishongeshwa muri ethane, peteroli ether.
DAAM ifite amatsinda abiri agize ingaruka, ari yo N - amide na ketone, biroroshye cyane gukoresha copolymerisation hamwe n'indi monomer ya vinyl, bityo kwinjizwa kwa ketone carbonyl chemical properties bishobora gutuma polymer igera kuri crosslinking na graft reaction, ishobora gutegura kole zitandukanye, thickener, paper reinforcement agent, crosslinking agent, nibindi.
Yakoreshejwe cyane mu bintu bitandukanye nko gusiga irangi, kole, inganda zikora imiti ya buri munsi, epoxy resin curing agent, inyongeramusaruro za resin zishobora kubona urumuri, ibikoresho by'imyenda, ubuvuzi, n'ibindi.
1. Umuti wo kwita ku musatsi:
Kimwe mu bintu by'ingenzi biranga DAAM ni uko homopolymer cyangwa copolymer yayo idashonga mu mazi, ariko igipimo cyayo cyo kwinjiza amazi gishobora kugera kuri 20% ~ 30% by'uburemere bwayo, iyo ubushuhe bw'ibidukikije buri munsi ya 60%, ishobora no kurekura ubushuhe, hanyuma spray y'umusatsi ishobora gukorwa hakoreshejwe iyo miterere.
2. Resin ishobora kwangiza imiterere y'izuba:
Resine ishobora gufotora ikorwa na homopolymer yoroheje, ikomeye, irwanya aside na alkali ifite umuvuduko wo gufotora wa resine, igice kidafashwe n’ingaruka biroroshye gukurwaho nyuma yo kubishyira mu gikoresho, bityo ikagira imiterere isobanutse neza kandi ikomeye kandi irwanya amazi.
Indi mikoreshereze y'ingenzi ya DAAM ni uko ishobora gusimbura gelatin, ikoreshwa mu gufotora emulsions kandi bigoranye gusimburwa n'ibindi bikoresho byiza. Gelatin imaze igihe kinini ibura kubera ko ifite isuku nyinshi, toni 2500 za gelatin zitezwe gukoreshwa mu bikoresho bishobora kwanduza foto, mu gihe gelatin ifotora yo mu gihugu ari amagana gusa ubu.
3. Ikoreshwa mu gutegura inyandiko za pulasitiki zikozwe mu nyuguti
4. Ikoreshwa mu gukora kole:
ikoreshwa nk'umusemburo wo gukurura no kunoza ibintu bivanze na fibre, sima, ikirahure, aluminiyumu na PVC, hagati aho ishobora no gukandamizwa kugira ngo ikore kole zishobora kwitabwaho n'umuvuduko, kandi ishobora gukoreshwa nk'ikole zishobora kwitabwaho n'ubushyuhe ku mpapuro, imyenda na filime ya pulasitiki irimo allyl polymer.
5. Ikoreshwa mu bindi bice:
⑴ ishobora gukoreshwa nk'umuti uvura irangi rya epoxy, irangi rirwanya kwangirika ry'ubutaka bw'ubwato, irangi ryo munsi y'amazi ry'ubutaka bw'ubwato, irangi rya acrylic resin, irangi rya polyester rituzuye, nibindi;
⑵ Copolymer monomer ishongesha amazi ya DAAM yakoreshejwe neza mu gusobanura ibintu bikomeye byahagaze;
⑶ Ishobora gukoreshwa nk'ibikoresho byo gufata amashusho bya laser bikozwe n'ubushyuhe;
⑷ Ikoreshwa nk'ikirahure gikuraho ibintu bitoshye;
⑸ Ikoreshwa nk'ibigize resin ishobora gushonga mu mazi;
⑹ Ikoreshwa mu gusiga amarangi ashongeshwa n'amazi.
