Whakamahinga
Āwhina tātari: Kaihoko ārai-piki, here; Kaihoko whakapūmau; Kaiwhakarewa; Kaiwhakamarara; Whakapai ake i te kakano; Kaihoko whakamātotoru; Kaihoko maimoatanga wai. Kua tohua e te EEC mō te purenga o te pia. E ai ki te GB 2760-96, e kiia ana he āwhina tukatuka. E ai ki ngā ture EEC-HACSG, kaua e whakamahia ki te kai pēpi. Hei kaihoko ārai-piki, i Haina, e whakaaetia ana kia whakamahia ki roto i ngā reka paura me te whakamahinga mōrahi o te 50g/kg; ka taea hoki te whakamahi ki roto i te aihikirīmi me te whakamahinga mōrahi o te 40g/kg; ka taea hoki te whakamahi ki roto i te kirīmi māmā me te paura ngako huawhenua me te whakamahinga mōrahi o te 20.0g/kg. Ina pāngia ngā rōpū hydroxyl i roto i te macromolecule cellulose e te esterification, etherification rānei, he maha ngā hua whai hua ka taea te whakaputa. Ko ngā esters cellulose e whakamahia ana ko: cellulose nitrate, cellulose acetate, cellulose acetate butyrate me te cellulose xanthate. Kei roto i ngā etera cellulose: te methyl cellulose, te carboxymethyl cellulose, te ethyl cellulose, te hydroxyethyl cellulose, te cyanoethyl cellulose, te hydroxypropyl cellulose me te hydroxypropyl methyl cellulose, me ētahi atu. Hei tāpiri, kei reira ngā ranunga ester-ether derivatives. Ka taea te whakamahi i te microcrystalline cellulose ki ngā ahumahi pēnei i te kakahu, te hanga pia, te kai, me te hanga pepa.
Ko te tikanga, he iti ake te mātotoru o te cellulose moroiti-kiriata mō ngā hua kua whakamaroketia, ā, he nui ake te mātotoru mō ngā hua kua rehuhia. Ko te nui o te makuku he 5%. Ka taea te memeha o te cellulose moroiti-kiriata engari kāore e memeha i roto i te wai, kāore e memeha i roto i ngā waikawa waimeha, ngā whakarewa waro me ngā hinu, ka pupuhi, ā, ka memeha wāhanga i roto i ngā otinga kawakore waimeha. Mā te whakamarara i te paura cellulose moroiti-kiriata ki roto i te wai ka puta he tiēre mārama, he whakapiri rānei. Haunga ngā mea tino waimeha, ka mau tonu te pumau mō ngā tau maha.
Te Tākai me te Tukunga
hei whakaritenga a te kiritaki.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
