Methyl cellulose CAS 9004-67-5
He pani kaulahao lōʻihi ka Methyl cellulose no ka cellulose. ʻO ke kaumaha molekala awelika o ka methyl cellulose he 10000 a 220000, a he pauka keʻokeʻo a he mea fibrous paha ia i ka mahana o ka lumi. ʻAʻole ia he mea ʻawahia, ʻaʻole hoʻonāukiuki, a ʻaʻole hoʻi he allergenic, me kahi density pili maopopo o 0.35 a 0.55 (density pili maoli o 1.26 a 1.30).

Hoʻohana nui ʻia ka Methyl cellulose i ka ʻoihana kūkulu hale, e like me ke ʻano he mea hoʻopili no ka sima, ka mortar, ka debonding joint, a pēlā aku. Hoʻohana ʻia ma ke ʻano he mea hana kiʻiʻoniʻoni a me ka mea hoʻopili i nā mea hoʻonani, nā lāʻau lapaʻau, a me nā ʻoihana meaʻai. Hoʻohana ʻia ka Methyl cellulose ma ke ʻano he mea hoʻonui no ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka lole, kahi mea hoʻolaha no nā resins synthetic, kahi mea hana kiʻiʻoniʻoni no nā uhi ʻana, a me kahi mea hoʻomānoanoa. Hoʻomākaukau ʻia ka alkali cellulose mai ka pulp, a laila hoʻopili ʻia me ka chloromethane a i ʻole dimethyl sulfate i loko o kahi autoclave a hoʻomaʻemaʻe ʻia me ka wai mahana.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
