Hydroxypropyl Methylcellulose (HPMC) na Methylcellulose (MC) bụ ihe abụọ sitere na cellulose nke a na-ejikarị eme ihe na mpaghara dị iche iche. Ha nwere ọtụtụ ihe ndị a na-ahụkarị, dị ka ezigbo solubility, ndina, imepụta ihe nkiri na nkwụsi ike, ya mere a na-eji ya n'ọtụtụ ụlọ ọrụ.
Hydroxypropyl Methylcellulose (HPMC)
1. Ihe owuwu ụlọ:
A na-eji HPMC eme ihe n'ọtụtụ ebe dị ka ihe mgbakwunye maka ciment na ihe ndị dabeere na gypsum na ụlọ ọrụ ihe owuwu. Ọ nwere ike imeziwanye arụmọrụ ihe owuwu, njigide mmiri na mgbawa nke ihe ahụ, na-eme ka ihe ụlọ dị mfe ijikwa n'oge usoro ihe owuwu na imeziwanye àgwà nke ngwaahịa ikpeazụ.
2. Mkpuchi na agba:
Na mkpuchi na agba, HPMC na-eji dị ka thickener na stabilizer. Ọ nwere ike inye ọrụ nhịahụ dị mma, meziwanye mmiri na ọkwa nke mkpuchi ahụ, ma gbochie mkpuchi ahụ ka ọ ghara ịdaba na ịfụ n'oge usoro ihicha.
3. Ala ọgwụ:
A na-ejikarị HPMC eme ihe dị ka ihe mkpuchi, nrapado na thickener maka mbadamba nkume na mmepụta ọgwụ. Ọ nwere ezigbo bioacompatibility na nkwụsi ike, nwere ike ijikwa ọnụego ntọhapụ nke ọgwụ, ma melite nkwụsi ike na mmetụta nnabata nke ọgwụ.
4. Ụlọ ọrụ nri:
A na-eji HPMC eme ihe dị ka thickener, emulsifier na stabilizer na ụlọ ọrụ nri. A na-eji ya na-emepụta ice cream, jelii, condiments na ngwaahịa mmiri ara ehi, wdg, nke nwere ike imeziwanye ọdịdị na uto nke nri na ịgbatị ndụ ndụ nke nri.
5. Ngwaahịa nlekọta onwe onye:
A na-ejikarị HPMC eme ihe dị ka onye na-emepụta ihe na-emepụta ihe nkiri na ngwaahịa nlekọta onwe onye. A na-eji ya na mmepụta nke shampoo, conditioner, toothpaste and skin care, wdg, nke nwere ike imeziwanye nkwụsi ike na iji ahụmahụ nke ngwaahịa.
Methylcellulose (MC)
1. Ihe owuwu ụlọ:
A na-ejikarị MC eme ihe dị ka ihe na-ekpu mmiri, ihe na-ejide mmiri na ihe nkedo n'ime ihe owuwu ụlọ. Ọ nwere ike melite arụmọrụ nke ngwa ngwa na ngwa ngwa, meziwanye mmiri na njigide mmiri nke ihe, si otú ahụ na-eme ka arụmọrụ na mma dị mma.
2. Ogige ọgwụ:
A na-eji MC mee ihe dị ka ihe nkedo na disintegrant maka mbadamba nkume na ụlọ ọrụ ọgwụ. Ọ nwere ike melite ike n'ibu na nkwụsi ike nke mbadamba nkume, chịkwaa ọnụego ntọhapụ nke ọgwụ, melite nrụpụta ọgwụ na nnabata onye ọrịa.
3. Ụlọ ọrụ nri:
A na-eji MC eme ihe dị ka thickener, emulsifier na stabilizer na ụlọ ọrụ nri. A na-ejikarị ya emeputa jelii, ice cream, ihe ọṅụṅụ na ihe ọṅụṅụ mmiri ara ehi, wdg, ma nwee ike imeziwanye ọdịdị, uto na nkwụsi ike nke nri.
4. Akwa na ibipụta na agba:
N'ime ụlọ ọrụ textile na mbipụta na ịcha akwa, a na-eji MC eme ihe dị ka akụkụ nke slurry, nke nwere ike imeziwanye ike nkwụsị na nkwụsị nke textiles, na-eme ka adhesion nke agba na agba agba n'oge a na-ebipụta na ịcha akwa.
5. Ngwaahịa nlekọta onwe onye:
A na-ejikarị MC eme ihe dị ka thickener na stabilizer na ngwaahịa nlekọta onwe onye. A na-eji ya na mmepụta nke ncha ntutu, ihe mkpuchi, ude mmiri na ude, wdg, nke nwere ike imeziwanye ọdịdị na nkwụsi ike nke ngwaahịa ahụ ma melite mmetụta na ahụmahụ.
A na-ahụkarị àgwà na uru
1. Nchekwa na ihe ndakọrịta ndụ:
Ma HPMC na MC nwere nchekwa dị mma na biocompatibility, ma dabara adaba maka ubi nwere oke nchekwa chọrọ dị ka nri, ọgwụ na ngwaahịa nlekọta onwe onye.
2. Ntughari:
Ihe abụọ a na-emepụta cellulose nwere ọtụtụ ọrụ dị ka ndina, emulsification, stabilization, na nhazi ihe nkiri, nke nwere ike izute mkpa dị iche iche nke ngwa ngwa dị iche iche.
3. Solubility na nkwụsi ike:
HPMC na MC nwere ezigbo solubility na mmiri ma nwee ike ịmepụta otu ihe ngwọta na-edozi ahụ, nke kwesịrị ekwesị maka usoro nhazi dị iche iche na usoro chọrọ.
Hydroxypropyl methylcellulose (HPMC) na methylcellulose (MC), dị ka ihe ndị dị mkpa cellulose, na-eji n'ọtụtụ ụlọ ọrụ dị ka ihe ụlọ, ọgwụ, nri, mkpuchi na ngwaahịa nlekọta onwe onye. Site na arụmọrụ ha dị mma na mgbanwe dị iche iche, ha na-arụ ọrụ dị mkpa n'ịkwalite àgwà ngwaahịa na arụmọrụ, na-eme ka usoro mmepụta ihe na ịkwalite ahụmahụ onye ọrụ. Site na ọganihu nke sayensị na nkà na ụzụ na mgbasawanye na-aga n'ihu nke mpaghara ngwa, ihe abụọ a ga-anọgide na-egosi ikike ngwa ngwa na atụmanya ahịa n'ọdịnihu.
