Onye na-ahụ maka nkwonkwo gypsum HPMC cellulose ether

Ngwakọta nkwonkwo gypsum, nke a makwaara dị ka apịtị akọrọ ma ọ bụ nanị njikọ njikọ, bụ ihe eji arụ ọrụ na-ewu na ịrụzi mgbidi akọrọ.Ọ bụ isi ihe mejupụtara ya bụ gypsum ntụ ntụ, ịnweta sulfate dị nro nke a na-agwakọta na mmiri iji mepụta mado.A na-etinyezi tapawa a n'oghere, nkuku, na oghere dị n'etiti oghere akọrọ iji mepụta elu dị larịị, enweghị nkebi.

Hydroxypropyl methylcellulose (HPMC) bụ ether cellulose nke a na-agbakwunyekarị na ihe nkwonkwo plasta maka ọtụtụ ihe kpatara ya.A na-enweta HPMC site na cellulose, polymer eke dị na mgbidi cell osisi.Nke a bụ ụfọdụ isi akụkụ nke iji HPMC n'ime ihe jikọrọ plasta:

Njide mmiri: A maara HPMC maka ọmarịcha njide mmiri.Mgbe etinyere ya na ngwakọta plasta, ọ na-enyere aka igbochi ngwakọta ịsachapụ ngwa ngwa.Ogologo oge na-arụ ọrụ na-eme ka ọ dị mfe itinye na imecha ihe nkwonkwo.
