Ngā tono

A: Mara polymerization: he pai mō te whakarite i te rahi matūriki reo-rahi o te vinyl acetate, te acrylic acetate me te emulsion acrylic parakore. Ka tohaina ki te N-hydroxyl me te kore e whakaiti i te mahi hononga whakawhiti. Ina whakamahia me ngā emulsifiers pēnei i te MA-80 me te IB-45, ka taea te whakapai ake i te rahi matūriki me te whakaputa i te piri pai ake.

B: Ngā mara kore-pūmua: ngā kaihoko horoi, ngā hua matū me ngā hopi horoi he mana patu huakita; te sima pahuka, ngā panera pakitara me ngā piripiri; he kaha pai ki te kawe i ngā surfactants cationic me ngā cation polyvalent. He pai te whakarewa-whakanui me te whakamarara mō ngā pūnaha kapia me te tae me te uara HLB reo.

Mahi
He pai te pumau o ngā irahiko me te pumau ā-pūkaha

1. Whakaahuahia
He momo emulsifier matua pai rawa atu a M30, kāore i roto i a ia te APEO, te propylene parakore, te acetate propylene, te styrene propylene me te pūnaha polymerization emulsion EVA. Ka whakakotahi a M30 i ngā rōpū anionic polar me ngā rōpū kore-ionic kore-polar, ā, mā tēnei hanganga ngota ahurei ka taea e te emulsion te whai pumau electrolyte me te pumau miihini.

2. Ngā mahi matua me ngā painga
Kāore i te whakaurua a APEO

He pai te whakarewa-whakanui me te whakamarara mō ngā pūnaha kapia me te tae me te uara HLB reo.

4. Whakamahinga
Mō te mahi pai rawa atu, e taunakihia ana kia whakaranua, kia tāpirihia hoki, ā, ko te whakamahinga e whakawhirinaki ana ki te pūnaha tono. Me whakatau e te kaiwhakamahi te nui o te tāpiri pai rawa atu mā te whakamātautau i mua i te whakamahinga.

5. Whakamahinga
a.Ko te horopeta kua tūtohutia hei emulsifier matua ko te 0.8-2.0%
b. Mō te hopi horoi, te wai kaukau me ētahi atu hua, ko te horopeta kua tūtohutia ko te 4.0-8.0%

6. Te rokiroki me ngā kete
A. He mea hanga ki te wai ngā whakamomona/tāpiri katoa, ā, kāore he mōrearea o te pahūtanga ina haria.
B. 200 kg/rino/pahu kirihou. 1000 kg/pareti.
C. He kōwhiringa te whakamahi i te takai ngāwari e tika ana mō te ipu 20 putu.
D. Penapena ki te wāhi hauhautanga, maroke hoki. E 24 marama te roa o te rokiroki.
