Usoro HPMC maka ụlọ na agba

Hydroxypropyl methylcellulose (HPMC maka mkpụmkpụ) bụ ihe dị mkpa ether agwakọtara agwakọta, nke bụ polima na-agbaze na mmiri na-abụghị ionic, a na-ejikwa ya nke ọma na nri, ọgwụ, ụlọ ọrụ kemịkalụ kwa ụbọchị, mkpuchi, mmeghachi omume polymerization na owuwu dị ka nkwụsịtụ mgbasa, ịka nká, emulsifying, stabilizing na gluu, wdg, enwere nnukwu oghere n'ahịa ụlọ.

Ebe ọ bụ na HPMC nwere ihe ndị dị mma dịka ịka nká, emulsification, nhazi ihe nkiri, colloid nchebe, njigide mmiri, njikọta, iguzogide enzyme na enweghị ike metabolism, a na-ejikarị ya eme ihe n'ọtụtụ ebe na mkpuchi, mmeghachi omume polymerization, ihe owuwu ụlọ, mmepụta mmanụ, ákwà, nri, ọgwụ, seramiiki eji kwa ụbọchị, ngwaọrụ eletrọnịkị na mkpụrụ ọrụ ugbo na ngalaba ndị ọzọ.

N'ihe gbasara ihe owuwu ụlọ, a na-etinye HPMC ma ọ bụ MC na simenti, ngwa agha, na ngwa agha iji melite ihe owuwu na ihe eji echekwa mmiri.

Enwere ike iji HPMC na:

1) Ihe na-eme ka ihe na-arapara ma na-eme ka ihe dị nro maka teepu gypsum;

2) Njikọ nke brik, taịlị na ntọala nke e ji simenti mee;

3) Stucco nke e ji plastaboard mee;

Wihe na-agbaze agbaze

HPMC bụ otu n'ime polima ndị na-agbaze mmiri, ike mmiri ya na-agbazekwa na-adabere na ọdịnaya nke otu methoxyl. Mgbe ọdịnaya nke otu methoxyl dị ala, enwere ike ịgbaze ya na alkali siri ike ma enweghị ebe a na-etinye thermodynamic. Site na mmụba nke ọdịnaya methoxyl, ọ na-enwe mmetụta karịa na mmiri na-aza ma na-agbaze na alkali na alkali na-adịghị ike. Mgbe ọdịnaya methoxyl dị >38C, enwere ike ịgbaze ya na mmiri, enwere ike ịgbazekwa ya na hydrocarbons halogenated. Ọ bụrụ na etinyere acid oge na HPMC, HPMC ga-agbasa ngwa ngwa na mmiri na-emepụta ihe ndị na-anaghị agbaze agbaze.
