whakataki poto mō te hua
He tino ngāwari te whakakotahitanga o te diacetone acrylamide me ngā rōpū tauhohe e rua: N – amides whakakapinga me te ketone, ethylene me te monomer copolymerization me ētahi atu, nō reira, ka whakauruhia te ketone carbonyl ki roto i te polymer, mā te whakamahi i ngā āhuatanga matū ketone carbonyl, ka taea te hanga i te polymer/hononga peka pērā i te tauhohenga, i whakamahia hei whakarite i ngā momo piripiri, te whakamātotoru, te kaihoko whakakaha pepa, te kaihoko honohono, me ētahi atu. Kua whakamahia whānuitia i roto i te paninga, te piripiri, te ahumahi matū o ia rā, te kaihoko whakaora kapia epoxy, te āwhina kapia photosensitive, te āwhina kakahu, te hauora me te hauora me ētahi atu mara.

2, te ira rewa 57 ~ 58 °C
3, te pūwāhi kohua 120℃ (1.07 kPa), 93 ~ 100℃ (13.33 ~ 40.0 Pa)
4. Te mātotorutanga whanaunga 0.998 (60 °C)
5, he karaihe ma, he kōwhai paku rānei, kāore he tae i muri i te rewa.
6, wairewa i roto i te wai, methanol, chloromethane, benzene, acetonitrile, ethanol, acetone, tetrahydrofuran, ethyl acetate, styrene, n-hexanol me ētahi atu whakarewa waro, kāore e wairewa i roto i te petroleum ether (30 ~ 60 °C).
whakamahi
E kiia ana ko te diamine,N-(1,1-dimethyl-3-oxobutyl) kātahi ko te DAAM. Ko te whakamahinga o te DAAM penei:
⑴ Te whakamahinga ki te paninga makawe
Ko te āhuatanga nui o te diamine ko tōna homopolymer, copolymer rānei, kāore e wairewa i roto i te wai, engari he "manawa wai" tōna, ko te tere mimiti wai tae atu ki te 20% ~ 30% o tōna taumaha, ina iti iho i te 60% te haumākū o te taiao, ka taea hoki te tuku wai. Ka whakamahia tēnei āhuatanga hei hanga i te rehu makawe e whakapūmau ana i te rehu makawe me te kapia photosensitive me te diamine.
⑵ Te whakamahinga i roto i te kapia whakaahua-ātete
Mā te whakamahi i te kapia DIAMine homOPOLYMER TOTOKA, MĀRO, ĀRAI WAIKAWAI, KI TE HANGA I TE PHOTOSENSITIVE, ka taea te hanga i te kapia kia tere te whakaahua, kia ngāwari hoki te tango i te wāhanga kore-ahua i muri i te whakaaturanga, kia mārama ai te ahua, kia kaha ai, kia ātete ai hoki ki te whakarewa me te wai.
Ko tētahi atu whakamahinga nui o ngā diamine ko te whakakapi i te gelatin. Ka whakamahia te gelatin hei emulsion photosensitive, e whakamahi ana i te nuinga o ngā āhuatanga motuhake o te gelatin, nō reira kua uaua ki te kimi i tētahi hua pai hei whakakapi mōna mō ngā tau neke atu i te 100. Ka roa te wā e iti ana te gelatin whakaahua parakore i Haina, e matapaetia ana me 2500t te gelatin e hiahiatia ana mō ngā rauemi photosensitive o te kāinga, engari i tēnei wā he rau tana noa iho te hanga o te gelatin whakaahua o te kāinga.
(3) mō te whakarite i te pereti tā kirihou
(4) Te whakamahinga i roto i te piripiri
Ka taea te whakamahi hei whakarei me te whakapai ake i ngā hononga mō ngā matū muka, te sima, te karāhe, te konumohe me te polyvinyl chloride. Ka taea hoki te hanga hei piripiri tairongo pēhanga. Ka taea hoki te whakamahi hei piripiri tairongo wera mō te pepa, te kakahu me ngā kiriata kirihou kei roto ngā polymer kiriaku.
⑸ Te whakamahinga o ⑸ i roto i ētahi atu āhuatanga
Haunga ngā āhuatanga maha o runga ake nei o te tono, ka taea hoki te whakamahi whānuitia te diacetone acrylamide i roto i ētahi atu mara:
① Ka taea te whakamahi hei rongoā mō te kapia epoxy, te peita ārai waikura o raro kaipuke, te peita raro kaipuke i raro i te wai, te peita kapia kiriaku, te polyester kore mākū me ētahi atu paninga;
② I whakamahia pai te monomer copolymer wairewa-wai o te diacetone acrylamide hei whakamārama i ngā totoka i whakatārewatia;
③ ka taea te whakamahi hei rauemi tuhi taiaho wera;
④ Whakamahia hei ārai i te pōuri o te karāhe;
⑤ i whakamahia ki ngā rauemi tārua azo;
⑥ Whakamahia hei wāhanga kapia whakaahua-wairewa-wai.
mōkihi me te kawe
B. Ka taea te whakamahi i tēnei hua, 25KG, PĒKE
C. Penapenahia kia hiri ki roto i te wāhi hauhautanga, maroke, me te hauhautanga. Me hiri rawa ngā ipu i muri i ia whakamahinga i mua i te whakamahinga.
D. Me hiri pai tēnei hua i te wā e kawe ana kia kore ai e uru te makuku, te kawakore me te waikawa kaha, te ua me ētahi atu poke.
