ACETATE POLY ANTI-STATIC, ANTI-UULTRAVIOLET RANGI WHAKATAKI HIKO MO NGA KAKAHU AC9218

1. Atete alkali
Ko nga kaihoko kawakore ngoikore kaore i pakaru te muka acetate, he iti rawa te mate o te taumaha o te muka.Ka tutaki ana ki te kawakore kaha, ina koa te muka diacetate, he ngawari ki te deacetylate, ka hua te heke o te taumaha, te kaha me te heke o te modulus.Na reira, ko te uara pH o te otinga mo te rongoa cellulose acetate kaua e neke ake i te 7.0.I raro i nga tikanga horoi paerewa, he kaha te whakamarumaru o te maota, ka taea hoki te whakamaroke-ma ki te tetrachloroethylene.

2. Te ātete ki te whakarewa pararopi
Ko te acetate Cellulose he tino memeha i roto i te acetone, DMF me te waikawa acetic glacial, engari karekau i te waiwaro me te tetrachloroethylene.E ai ki enei ahuatanga, ka taea te whakamahi acetone hei whakarewa hurihuri o te muka acetate, ka taea te whakamahi te tetrachlorethylene ki te whakamaroke i te papanga muka acetate ma.
3. Atete waikawa

Ko te muka waikawa ahetiki he pai te pumau o te waikawa, a, ko te waikawa pungatara noa, te waikawa maaota me te waikawa nitric e kore e pa ki te kaha, te kanapa me te whakaroa o te muka i roto i tetahi awhe kukū.Engari ka taea te rewa i roto i te waikawa sulfuric concentrated, acid hydrochloric concentrated me te waikawa nitric concentrated.

4. Tae Tae

Ahakoa ko te cellulose acetate i ahu mai i te cellulose, i te wa o te esterification, he waahanga nui o nga roopu hydroxyl polar i runga i te mowhiti huka o te cellulose ka whakakapihia e nga roopu acetyl.Na reira, ko nga waikano e whakamahia nuitia ana i roto i te waikano muka cellulose he tata kore hononga ki te acetate cellulose, he uaua ki te tae.Ko nga waikano tino pai mo te muka acetate ko nga waikano marara he iti te taumaha ngota me te reiti tae rite.

He kanapa te tae o te muka acetate, te papanga ranei kua pania ki te waikano marara, he pai te awenga o te taumata, he nui te ngenge o te tae, he tere te tae me te chromatography.
