Hydroxyethyl Methyl Cellulose (HEMC)

Hydroxyethyl methyl cellulose (HEMC) bụ polymer soluble mmiri nke ewepụtara na cellulose.Ọ bụ ihe na-abụghị ionic, nke na-adịghị egbu egbu, na nke na-adịghị ere ọkụ nke a na-ejikarị eme ihe n'ọtụtụ ụlọ ọrụ mmepụta ihe na ngwa ahịa.A na-eji HEMC kpọrọ ihe maka ike ya ime ihe dị ka ihe na-agbapụta, ihe nkedo, na rheology modifier n'ọtụtụ ngwaahịa.

A na-eme HEMC site na iji kemịkal na-agbanwe eriri cellulose eke.N'ime usoro a, a na-eji sodium hydroxide agwọ eriri cellulose na-emepụta cellulose alkali.A na-agbakwunye Ethylene oxide na ngwakọta, nke na-emeghachi omume na cellulose iji mepụta hydroxyethyl cellulose.N'ikpeazụ, a na-agbakwunye methyl chloride na ngwakọta iji mepụta HEMC.

A na-eji HEMC n'ọtụtụ ngwa dị iche iche, gụnyere ihe owuwu, nri, nlekọta onwe onye, ​​na ọgwụ.Otu n'ime isi ihe eji HEMC eme ihe bụ ihe owuwu, ebe a na-eji ya na ngwaahịa dị iche iche dị ka ngwa ngwa mix mix, putties, tile adhesives, na gypsum ngwaahịa.

N'ime ngwa ngwa ngwakọta akọrọ, a na-eji HEMC mee ihe dị ka ihe na-ekpo ọkụ, ihe nkedo, na onye na-ejigide mmiri.Ọ na-enyere aka melite arụ ọrụ nke ngwa agha ma na-enye ohere ka mma ịchịkwa ọdịnaya mmiri.Nke a dị mkpa n'ihi na mmiri mmiri nke ngwa ngwa na-emetụta nkwụsi ike ya, ịtọ oge, na ike ikpeazụ.

Na putties, HEMC bụ nke a na-eji dị ka ihe na-esi ísì na ihe nkedo.Ihe mgbakwunye nke HEMC na ngwakọta na-enyere aka mee ka ọrụ nke putty dịkwuo mma ma na-enye ohere ijikwa ihe dị mma nke mmiri.HEMC na-enyekwa aka igbochi nkewa nke ihe dị iche iche dị na nhazi nke putty, ọ na-eme ka adhesion nke putty dịkwuo mma.

Na nrapado tile, HEMC na-ejikarị eme ihe dị ka onye na-ejigide mmiri.Ihe mgbakwunye nke HEMC na ngwakọta na-enyere aka imeziwanye ọrụ nke nrapado na-enye ohere maka njikwa mma nke mmiri.HEMC na-enyekwa aka igbochi nkewa nke ihe dị iche iche dị na nhazi nke nrapado, ọ na-eme ka adhesion nke nrapado na-eme ka ọ dịkwuo mma.

N'ime ngwaahịa gypsum, a na-eji HEMC eme ihe dị ka ihe na-ekpo ọkụ, ihe nkedo, na onye na-ejigide mmiri.Ọ na-enyere aka melite arụmọrụ nke ngwaahịa gypsum ma na-enye ohere ijikwa ihe dị mma nke mmiri.Nke a dị mkpa n'ihi na mmiri nke ngwaahịa gypsum na-emetụta oge nhazi ya na ike ikpeazụ.

N'ime ngwaahịa nri, a na-ejikarị HEMC eme ihe dị ka ihe na-agba, stabilizer, na emulsifier.A na-eji ya n'ọtụtụ ụdị nri dị iche iche, gụnyere sauces, uwe, na ngwaahịa mmiri ara ehi.A na-eji HEMC kpọrọ ihe maka ike ya iji melite nhazi na nkwụsi ike nke ngwaahịa ndị a.

N'ime ngwaahịa nlekọta onwe onye, ​​a na-eji HEMC eme ihe dị ka ihe na-agba, stabilizer, na emulsifier.A na-eji ya n'ọtụtụ ụdị nlekọta onwe onye, ​​​​gụnyere shampoos, conditioners, na lotions.A na-eji HEMC kpọrọ ihe maka ike ya iji melite nhazi na nkwụsi ike nke ngwaahịa ndị a.

Na ọgwụ, HEMC na-eji dị ka ihe nkedo na disintegrant.A na-eji ya eme ihe n'ụdị mbadamba iji kwalite ike ọrụ mbadamba nkume na iji nyere aka n'ịgbasa na mgbaze n'ime ahụ.
