YDN535 Yakazara Mvura-inotakurwa Yakakwira Imino Methylated Melamine Resin

Usage

Inokodzera mvura-inotakurwa nematanda lacquer coatings, emulsion pendi masisitimu, uye mamwe-anonyungudika emvura masisitimu ekuputira.

Hunhu

YDN535 resin is a partially methylated melamine-formaldehyde resin ine yepakati dhigirii yealkylation, yakakwira methylol yemukati, uye yakakwirira imino mashandiro.

YDN535 ine kuenderana kwakanaka nemvura-inonyungudika anionic polima, dispersants, uye emulsions.

YDN535 resin inozvigadzirisa zvakanyanya, inovandudza kuoma kwefirimu uye kuwedzera kupisa kwekudzivirira kwemapolymer anonyungudika nemvura.

YDN535 inogona kugadziridzwa kuita isina kwayakarerekera pH ine amine kuti iwane kugadzikana kwakakodzera, uye inogona kuchengetedza kugadzikana nechero amine bridging agent ine pH iri pakati pe7.0 ne8.5.

YDN535 inoda isina kusimba asidhi inokonzeresa pasi peyakajairwa kubheka mamiriro.Kushandisa isina kusimba asidhi (organic kana inorganic acid) sechinhu chinokonzeresa kuumbwa kwemafirimu kunoshanda zvakanyanya.

Zhejiang Yadina New Material Technology Co., Ltd., yaimbozivikanwa seJiaxing Hangxing Fine Chemical Co., Ltd., yakavambwa muna 2002. Ibhizimusi renyika repamusoro-soro rinobatanidza tsvakiridzo nebudiriro yakazvimirira, kugadzirwa kwehunyanzvi uye kutengesa melamine yakagadziridzwa. resin uye melamine foam.

Kambani yedu yaive nyanzvi mukugadzira melamine resin kubva pakuvambwa.Pamusoro pe tekinoroji yedu yakakura melamine resin tekinoroji, isu takawedzera tekinoroji yedu uye kugadzira kune melamine foam indasitiri.Isu takagadzira yedu rabhoritari yekuenderera mberi nekutsvagisa uye kuvandudza kwe melamine resin uye melamine foam zvinhu.Kupfuura makore isu takawana gumi nematatu ekutanga patents uye gumi nematatu utility modhi patents emelamine foam plastiki zvinhu uye tekinoroji yekugadzira.Isu ndisu chete nyanzvi mugadziri munyika uye kunze kwenyika anogona kugadzira akasiyana akatevedzana e melamine foam mapurasitiki ezvigadzirwa, kusanganisira semi-rigid melamine foam, iyo yakanyorera patent muUnited States neJapan uye iri kuongororwa zvakanyanya.

Kunze kwekugona kwepamusoro kwekunyudza kwemvura, furo redu remelamine zvakare rine ruzha rwakanyanya uye kugona kwekupisa kwekudzivirira zvakare.Nyaya yacho yave ichishandiswa kwete mukuchenesa imba chete, asi zvakanyanya muminda yeindasitiri, semuenzaniso simba bhatiri insulation zvinhu, aerospace Ultra-light materials, flame-retardant building materials, acoustic materials, etc. Iine yakakwana uye yakasimbiswa yemhando yekutonga system, kambani yedu yanga yakaongororwa nevatengi vedu muzvigadzirwa zvedu zvemhando yepamusoro uye mitengo yemakwikwi.
