Mpaghara ngwa nke hydroxy propyl methylcellulose

Hydroxy propyl methylcellulose (HPMC) bụ ihe sịntetik nke cellulose nke a na-ejikarị eme ihe na ngwa ụlọ ọrụ dị iche iche n'ihi na ọ na-emepụta ihe nkiri dị mma, njide mmiri, na ihe na-eme ka ọ dị arọ. HPMC bụ ọcha na-acha ọcha, enweghị isi, na ntụ ntụ na-enweghị ụtọ nke na-agbaze na mmiri oyi, na-eme ka ọ dị mfe ịrụ ọrụ na ọtụtụ ngwa dị iche iche. Nke a bụ ụfọdụ mpaghara ngwa ngwa maka HPMC:

  1. Ụlọ ọrụ ihe owuwu

A na-eji HPMC eme ihe n'ọtụtụ ebe na ụlọ ọrụ ihe owuwu dị ka ihe na-agbapụta mmiri, ihe na-ejide mmiri, na ihe nkedo. A na-ejikarị ya eme ihe na ngwaahịa simenti, dị ka ngwa agha, grouts, na renders, iji kwalite ịrụ ọrụ, nrapanye, na ịdịte aka. A pụkwara iji HPMC mee ihe dị ka ihe mkpuchi maka bọọdụ gypsum yana mmanụ mmanu na mmepụta nke tileti seramiiki.

  1. Ụlọ ọrụ ọgwụ

A na-eji HPMC eme ihe n'ọtụtụ ebe na ụlọ ọrụ ọgwụ dị ka ihe na-emepụta ihe, nke bụ ihe na-adịghị ahụkebe nke a na-agbakwunye na ọgwụ iji nyere aka na nnyefe ya, ntinye ya na nkwụsi ike. A na-ejikarị ya eme ihe dị ka ihe nkedo, ihe na-agbasa, na onye na-ewepụta ya na mbadamba na capsules. A na-ejikwa HPMC na ngwọta anya na n'imi sprays dị ka ihe nkwalite viscosity na mmanu mmanu.

  1. Ụlọ ọrụ nri

A na-eji HPMC na ụlọ ọrụ nri dị ka emulsifier, thickener, na stabilizer. A na-ejikarị ya eme ihe na ngwaahịa mmiri ara ehi, dị ka ice cream, iji meziwanye udidi na igbochi nhazi ice crystal. A pụkwara iji HPMC mee ka nri kwụsie ike, mgbakwasa salad, na ofe. Tụkwasị na nke a, a na-eji HPMC mee ihe mkpuchi maka mkpụrụ osisi na akwụkwọ nri ọhụrụ iji gbochie nkwụsị mmiri na ịgbatị ndụ.

  1. Ụlọ ọrụ nlekọta onwe onye

A na-ejikarị HPMC eme ihe n'ụlọ ọrụ nlekọta onwe onye dị ka ihe na-agbakọ, ihe nkedo, na onye na-eme ihe nkiri na ngwaahịa ịchọ mma, dị ka lotions, creams, na shampoos. Ọ na-enyere aka imeziwanye ọdịdị na nkwụsi ike nke ngwaahịa ndị a ma na-enyekwa moisturize na nhazi ihe. A pụkwara iji HPMC mee ihe dị ka onye na-akwụsịtụ maka ihe ndị na-adịghị edozi ahụ yana dị ka ihe nkwụnye maka emulsions.

  1. Ụlọ ọrụ mkpuchi

A na-eji HPMC na ụlọ ọrụ mkpuchi dị ka ihe nkedo, ihe nkiri na-emebu, na thickener. A na-ejikarị ya eme ihe na mkpuchi mmiri, dị ka agba na varnishes, iji meziwanye adhesion, ịdịte aka, na ihe ndị na-asọpụta. HPMC nwekwara ike iji dị ka thickener na-ebi akwụkwọ ink na dị ka ihe mkpuchi mkpuchi maka metal elu.

  1. Ụlọ ọrụ textile

A na-eji HPMC na ụlọ ọrụ akwa dị ka ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-esi ísì ụtọ maka mpempe akwụkwọ textile. Ọ na-enyere aka melite adhesion nke mpempe akwụkwọ na-ebi akwụkwọ na akwa ákwà ma na-enyekwa ezigbo njide mmiri.

  1. Ụlọ ọrụ mmanụ na gas

A na-eji HPMC na ụlọ ọrụ mmanụ na gas dị ka ihe mgbakwunye mmiri na-egwupụta ihe. A na-eji ya belata mfu mmiri ma mee ka olulu mmiri guzosie ike n'oge a na-egwupụta ihe. Enwere ike iji HPMC dị ka ihe mgbakwunye mmiri na-agbaji agbaji iji kwalite viscosity na nkwusioru proppant.

N'ikpeazụ, hydroxypropyl methylcellulose (HPMC) bụ polymer dị iche iche na nke a na-ejikarị eme ihe nke na-achọta ngwa n'ime ụlọ ọrụ dị iche iche n'ihi nhazi ihe nkiri dị mma, njide mmiri, na ihe na-eme ka ọ dị elu. Ihe owuwu ahụ, ọgwụ, nri, nlekọta onwe onye, ​​mkpuchi, akwa akwa, mmanụ na gas bụ ụfọdụ n'ime isi ebe a na-eji HPMC eme ihe.
