Kaihanga Utu Pai VAE EMULSION(VAE) CAS:24937-78-8

Utu Pai a te Kaihanga VAE EMULSION (VAE) CAS: 24937-78-8 Whakaahua Matua

whakaahuatanga poto:

Ka whiwhihia te VAE EMULSION (VAE) mā te kohikohi i te ethylene me te ethyl acetate kia rite ki ngā ōwehenga rerekē. Ko te whakarāpopototanga reo Pākehā o te EVA e tohu ana i te hanganga ethylene, ko te VA e tohu ana i ngā wāhanga ethylene acetate. He hononga tata te ihirangi. E ai ki ngā ihirangi VA rerekē, ka taea te wehewehe i te VAE EMULSION (VAE) ki ngā wāhanga e toru: ko te ihirangi VA he 5% (40%) e kiia ana he kirihou EVA, e whakamahia ana mō te whakarerekētanga polyethylene, te hanga waea me ngā taura, ngā kiriata angiangi, me ētahi atu hua hanga me te ranunga; ko te ihirangi VA he 40% -90% e kiia ana he rapa EVA, e whakamahia ana mō te rapa, ngā taura me ngā wāhanga ahumahi motuka. Ko te ihirangi VA he teitei ake i te 90%, e kiia ana he polyache acetate emulsion lotion, ā, e whakamahia ana mō ngā piripiri, ngā paninga, me ētahi atu.

Ngā tono a te VAE

Tāpirihia te kāpia matū-1, te matū pahuka/whakatakoto ki te kāpia motuhake, he hinu kiriuhi vinyl acetate ethylene copolymer kounga teitei. He tino pai te matotoru tīmatanga me te pumau ā-mīhini. Ki te whakatauritea ki te hinu kiriuhi polyvinyl acetate, ka taea te whakapai ake i tōna tere whakamaroke, te piri me ētahi atu āhuatanga tono. He pai te piri ki te kiriata kirihou me te pepa konumohe, he ngawari pumau ki ngā mea hanga pepa, ā, he whānuitia ngā tauira.

He pai te ātete pānga me te pakaru o te ahotea o te Ethylene-ethyl acetate communist, he ngawari, he ngāwari teitei, he ārai-pū me te pumau matū, he pai te mahi hiko, he pai te hototahi ki te koiora, he iti te kiato, me ngā whakakī, he pai ake te hototahi o te kaihoko ārai mura. He rerekē te ihirangi EVA mai i te VA, mai i te kirihou, te rapa, ki te emulsion ChemicalBook, ā, he whānui te whānuitanga o te tono, he pai mō te pēhi, te hanga werohanga, te pupuhi kirihou, te paninga, te hanga wera me ētahi atu tikanga tukatuka. Ka taea te whakamahi ki ngā taura. Ngā wāhanga hiri, te tiaki hauora, te kiriata whakamatao, ngā paipa, ngā rauemi pereti, ngā rauemi hanga, ngā taputapu hiko, ngā taputapu motuka me ngā mea e hiahiatia ana i ia rā.

Taumaha ngota: 342.43

Tātai Hanganga Ngota:

Ngā Āhuatanga: Ko te whakamārama poto mō te VAE he whakauru i te rōpū vinyl acetate (VA) ki roto i te hanganga mekameka roa o te polyethylene (PE), ko te nui o te VA te mea nui e pā ana ki tana mahi, nā te mea he rōpū polar te VA. Mā te pikinga ake o te nui o te VA, ka heke te tioata, ā, ka pai ake te ngāwari, te ātete pānga me te ātete hinu. Heoi, mā te pikinga ake o tōna polarity, ka piki ake te hototahitanga ki ngā whakakī, ā, ka paku piki ake hoki te ātete mura.
