YDN535 Katoa-Wai-whanau High Imino Methylated Melamine Resin
Whakamahinga
He pai mo nga whakakikorua wai-wairewa rakau, punaha peita whakaehunga, me etahi atu punaha whakakikorua wairewa.
Nga ahuatanga
Ko te kapia YDN535 he kapia melamine-formaldehyde he wahanga methylated me te tohu waenga o te alkylation, te ihirangi methylol teitei, me te mahi imino teitei.
He pai te hototahi o te YDN535 ki nga polymers anionic wairewa-wai, dispersants, me nga whakaehunga.
Ko te kapia YDN535 he tino whakamaarama, he whakapai ake i te pakeke o te kiriata me te whakanui ake i te parenga wera o nga polymers wairewa-wai.
Ka taea te whakatika i te YDN535 ki te pH koretake me te amine kia pai ai te pumau, ka taea te mau tonu me tetahi kaihoko piriti amine me te pH i waenga i te 7.0 me te 8.5.
Kei te hiahia a YDN535 ki te whakakorikori waikawa ngoikore i raro i nga tikanga tunu.Ko te whakamahi i te waikawa ngoikore (waikawa pararopi ranei) hei whakakorikori mo te hanga kiriata he tino whai hua.

Mo matou
Ko Zhejiang Yadina New Material Technology Co., Ltd., i mohiotia i mua ko Jiaxing Hangxing Fine Chemical Co., Ltd., i whakaturia i te tau 2002. He hinonga hangarau teitei o te motu e whakauru ana i te rangahau motuhake me te whakawhanaketanga, te hanga ngaio me te hoko o te melamine whakarereke. kapia me te pahuka i te melamine.
He tohunga to taatau kamupene ki te whakaputa kapia melamine mai i te whakaturanga.I runga ake i o maatau hangarau kapia melamine pakeke, kua whakawhänuihia e mätou o mätou hangarau me te hanga ki te ahumahi pahuka melamine.Kua whakaritea e matou to matou ake taiwhanga mo te rangahau tonu me te whakawhanaketanga o te kapia melamine hou me nga taonga pahuka melamine.I roto i nga tau kua whiwhi matou 13 nga patent tenenga me te 13 tauira whaipainga mo nga rauemi kirihou melamine pahuka me ona hangarau whakaputa.Ko matou anake te kaihanga ngaio i roto i te motu me te ao ka taea te whakaputa i nga momo momo hua kirihou pahuka melamine, tae atu ki te pahuka melamine ahua-maroke, kua tono mo nga patent i Amerika me Hapani, a kei raro i te tirotiro nui.
I tua atu i te kaha o te whakauru wai, he pai hoki to tatou pahuka melamine me te kaha o te oro me te wera wera.Ko nga rauemi kua whakamahia ehara i te mea mo te horoi whare anake, engari he nui noa atu i roto i nga mara ahumahi, hei tauira, nga taputapu hiko hiko hiko, nga rauemi maamaa-aerospace, nga taputapu hanga mura, nga taonga oro, me etahi atu. kua arohaehaehia ta matou kamupene e o taatau kaihoko ki o maatau hua kounga teitei me te utu whakataetae.
