Ko te hanganga karaihe o te waikawa hakihaki e whakaatu ana kua herea nga ngota ki nga rauropi, me te waikawa acetic me te ahua o te waikawa iti. Te whakatau taumaha ma te whakakore i te whakaheke tohu me te rereke x-ray. I te wa ka rewa te waikawa acetic ki te wai, ka tere te pakaru o nga here hauota i waenga i nga paru. Ko etahi atu o te waikawa carboxylic e whakaatu ana i te waa rereke.
Ko nga mea katoa e whakaratohia ana e Exprights®: Ihirangi / Whiteney / Parea / Phlvalingyle / Tae Atu me etahi atu hua motuhake.

Te whakamahi hua
Whakamahia te ahumahi
1. Ko te waikawa acetic he hua matū nui, ko tetahi o nga waikawa o te waikawa tino nui. Kei te whakamahia te nuinga mo te hanga o te anhydride acetic, acetate me te cellulose acetate. Ka taea e te Acetate te acetate te hangai ki nga kiriata me nga piriti, a ko ia ano hoki te rauemi raw o te muka synthetic vinylon. Whakamahia ai te acetate acetate hei hanga i te kiriata ayon me te kiriata pikitia.
2. Na te mea ka rewa te waikawa acetic te nuinga o nga mea o te rauropi, ka whakamahia ano hoki hei whakarewa raupaparorohiko (hei tauira mo te waikawa o te p-xyene hei whakaputa i te waikawa terephthalic).
3. Ka taea te whakamahi i te waikawa acetic i etahi rongoā piihi me te aukati i te raima ngoikore, ka taea e te Candmium te whakakii i te ahua o te bincholy, me te whakamahi i te pH o te pati ngoikore.
4 Ko te Acetate arahi he peita peita he ma; Ko te Tetraacetate he tohu whakahiato (hei tauira, ka taea te whakamahi i te tetracetate kaha, ka whakaputa i te acetoxy me te whakarite i nga pūhui waro, me te whakarite pūhui waro, me etahi atu.

Whakamahi Kai
I roto i te umanga kai, ka whakamahia te waikawa acetic hei kaimoana, te kaihoko whakakakara me te kakara, ka rewa te waikawa hakihaki ki te 4-5% me te wai, me nga momo kai reka. He rite te hakari ki te winika waipiro, he poto te wa hangahanga, he iti te utu. Ka rite ki te kaihoko punawai, ka taea te whakamahi mo te whakahiato, te whakarite i te winika, te tiihi me te tiihi, kia rite ki nga hiahia whakaputa. Ka taea hoki te tito i te kakara ki te whakarei i te waina whakakakara, ko te nui o te whakamahinga ko te 0.1 ~ 0.3 g / kg.
