Kedu otu esi eji HPMC eme ihe?

Hydroxypropyl methylcellulose (HPMC) bụ ụdị ether cellulose nke a na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu.Ọ bụ polymer na-agbaze mmiri nke a na-eji dị ka ihe mgbakwunye n'ọtụtụ ihe owuwu ụlọ, dị ka simenti, kọnkịtị, ngwa agha, na plasta.A na-eji HPMC arụ ọrụ iji melite njirimara nke ihe ndị a, dị ka ịrụ ọrụ, njide mmiri, na adhesion.

HPMC bụ polymer sịntetik ewepụtara na cellulose, nke bụ polymer eke achọtara na osisi.A na-eme ya site na iji propylene oxide meghachi omume cellulose wee hydroxypropylating ya.Usoro hydroxypropylation na-agbakwụnye ìgwè hydroxyl na mkpụrụ ndụ cellulose, nke na-eme ka ha na-agbaze na mmiri.Nke a na-eme ka HPMC bụrụ nnukwu mgbakwunye maka ihe owuwu, ebe ọ nwere ike melite njirimara nke ihe ndị a na-agbanweghị ihe mejupụtara kemịkalụ ha.

Enwere ike iji HPMC mee ihe n'ụdị ihe owuwu dị iche iche, dị ka ciment, konkịtị, ngwa agha, na plasta.Na ciment, HPMC nwere ike iji mee ka arụ ọrụ nke ngwakọta ahụ dịkwuo mma, yana iji belata mmiri chọrọ maka nkwekọ enyere.Nke a nwere ike inye aka belata ọnụ ọgụgụ ciment achọrọ maka ọrụ enyere, yana ibelata ụgwọ ọrụ ahụ.A pụkwara iji HPMC mee ihe na ihe iji meziwanye ọrụ na njigide mmiri nke ngwakọta.Nke a nwere ike inye aka belata oke mmiri a chọrọ maka nkwekọ enyere, yana ibelata ụgwọ ọrụ ahụ.

N'ime ngwa agha na plasta, enwere ike iji HPMC mee ka mmachi nke ngwa agha ma ọ bụ plasta dị na mkpụrụ.Nke a nwere ike inye aka belata oge na mgbalị a chọrọ iji tinye ngwa ngwa ma ọ bụ plasta, yana ibelata ụgwọ ọrụ ahụ.A pụkwara iji HPMC kwalite njide mmiri nke ngwa agha ma ọ bụ plasta, nke nwere ike inye aka belata oke mmiri achọrọ maka nkwekọ.

N'ozuzu, HPMC bụ ihe mgbakwunye na bara uru maka ihe owuwu ụlọ.Enwere ike iji ya kwalite ịrụ ọrụ, njide mmiri, na nrapado nke ciment, ihe, ngwa ngwa, na plasta.Nke a nwere ike inye aka belata oge na mgbalị achọrọ maka ọrụ enyere, yana ibelata ụgwọ ọrụ ahụ.
