ʻO ka mea hoʻopili plastik DMM Dimethyl Maleate CAS 624-48-6
Dimethyl Maleate (DMM)
ʻO ke ʻano kemika a me ke kaumaha molekala
Kemika formula: C6H8O4
Kaumaha molekole: 144.12
Helu CAS:624-48-6
Nā waiwai a me nā hoʻohana
Wai ʻaila ʻaʻohe kala, moakaka, bp 115 ℃ (3mmHg), helu refractive 1.4283 (20 ℃).
Hoʻohana ʻia ma ke ʻano he plasticizer kūloko, hiki ke copolymerized me nā monomers e like me vinyl chloride, vinyl acetate, styrene, a pēlā aku.
Hoʻohana ʻia hoʻi ma ke ʻano he waena organik no ka synthesizing ʻana i nā huahana he nui e like me ka huahana o ke kūʻē ʻana i ka radiation ultraviolet, a pēlā aku.

Pūʻolo a me ka mālama ʻana, palekana
Hoʻopili ʻia i loko o ka pahu hao galvanized 200 lita, ʻupena kaumaha 220 kg / pahu.
Mālama ʻia ma kahi maloʻo, malu, a me ka ea. Pale ʻia mai ke kuʻi ʻana a me nā kukuna o ka lā, ka ua i ka wā e lawelawe ai a me ka hoʻouna ʻana.
Inā hālāwai ʻoe me ke ahi wela a moakāka a i ʻole e hoʻopili aku i ka mea hoʻomake oxidizing, e hoʻoweliweli i ka ʻā ʻana. Inā hālāwai ʻoe me ka wela nui, e hoʻonui ʻia ke kaomi i loko o ka pahu, a laila e hoʻoweliweli i ka Bang.
Inā pili ka ʻili i nā lole i haumia, e holoi pono me ka wai nui a me ke kopa. Inā pili ka maka, e holoi koke me ka wai nui me ka wehe ʻana o ka lihilihi no nā minuke he ʻumikūmālima. E kiʻi i ke kōkua lapaʻau.
E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou e kiʻi i ka COA a me ka MSDS. Mahalo.
