Hydroxypropyl Methyl Cellulose (HPMC, Hydroxypropyl Methyl Cellulose) bụ ihe eji eme ihe n'ọtụtụ ebe na ntụ ntụ putty. Ọ nwere ezigbo mmiri solubility, adhesion, njigide mmiri, ịgbara mmiri, imepụta ihe nkiri na mmanu, ya mere ọ na-arụ ọrụ dị mkpa na ntụ ntụ putty.
1. Njide mmiri
Otu n'ime ọrụ kachasị mkpa nke HPMC na ntụ ntụ putty bụ inye ezigbo njigide mmiri. Putty ntụ ntụ na-akpọnwụ mgbe etinyere ya, ebe HPMC na-ejigide mmiri ma na-agbatị oge ihicha. Njirimara a na-enye ohere ka ntụ ntụ putty nwee ogologo oge na-arụ ọrụ n'oge usoro ọgwụgwọ, nke bara uru na-ewu ụlọ. Njide mmiri na-egbochikwa mgbawa nke oyi akwa putty, na-eme ka ike na nkwụsi ike nke ngwaahịa emechara.
2. Ịba ụba
Dị ka onye na-emepụta ihe, HPMC nwere ike ịbawanye viscosity nke ntụ ntụ ntụ ntụ, na-eme ka ntụ ntụ na-agbapụta karịa na ọbụna mgbe etinyere ya. Ọ nwere ike ịgbanwe agbanwe agbanwe nke putty ntụ ntụ iji zere ihe na-eme ka ọ ghara ịdị na-eme ihe na ihe isi ike na-ewu ụlọ, si otú ahụ na-eme ka a na-ekpuchi ntụ ntụ na mgbidi na-enweghị mmiri, na-eme ka mma ụlọ dị mma.
3. Ihe na-emepụta ihe nkiri
Ihe nkiri nke HPMC mere n'oge usoro ihicha nwere ike ime ka ike dị elu na ịdịte aka nke ntụ ntụ putty. Ihe ndị na-emepụta ihe nkiri bụ ihe dị mkpa na-eme ka ntụ ntụ nke putty nwee ike iguzogide mgbawa na iyi. Ihe owuwu ihe nkiri a nwere ike ọ bụghị naanị igbochi mgbawa elu nke oyi akwa putty, kamakwa kwalite nguzogide nke oyi akwa na gburugburu ebe obibi, dị ka nguzogide UV na mgbochi mmiri.
4. mmanu mmanu
HPMC nwere mmanu mmanu ma na-enyere aka melite arụmọrụ owuwu nke ntụ ntụ putty. N'oge a na-agwakọta na-ewu usoro nke putty ntụ ntụ, mmetụta lubrication nke HPMC na-eme ka ọ dị mfe ịkwanye ntụ ntụ ahụ nke ọma ma tinye ya na mgbidi ahụ nke ọma. Ọ bụghị nanị na nke a na-eme ka ihe owuwu dị mma, ma ọ na-ebelatakwa ike nke ngwá ọrụ ihe owuwu.
5. Nkwụsi ike
HPMC nwere ike imeziwanye nkwụsi ike nke ntụ ntụ putty. Ọ nwere ike igbochi putty ntụ ntụ na-edozi, agglomerating na nsogbu ndị ọzọ n'oge nchekwa ma hụ na nkwụsi ike nke ngwaahịa ahụ dị ogologo oge. Mmetụta a na-eme ka ahụ sie ike nke HPMC na-egbochi ntụ ntụ putty ka a na-akpali ya ugboro ugboro tupu ejiri ya ma nọgide na-enwe otu àgwà.
6. Melite arụmọrụ mgbochi-slip
Mgbe ị na-ewu mgbidi kwụ ọtọ, ma ọ bụrụ na uzuzu putty enweghị ezigbo ihe mgbochi na-adịghị mma, ọ na-adịkarị mfe ịkwaga na ịkwa ụda. The adhesion na ndim mmetụta nke HPMC budata mma mgbochi-slip arụmọrụ nke putty ntụ ntụ, n'ịhụ na ihe nwere ike ike ike ike na mgbidi na-etolite a ewepụghị, ezigbo elu.
7. welie constructability
Ịdị adị nke HPMC na-eme ka ntụ ntụ ntụ ntụ dị mfe iji wuo, na-ebelata nrapagide nke ngwaọrụ, ma na-eme ka arụ ọrụ ụlọ dịkwuo mma. Ọ nwere ike ime ka ntụ ntụ putty ghara ịkwado ngwaọrụ n'oge usoro ihe owuwu, belata nguzogide n'oge ngwa, ma melite nkasi obi na mmetụta nke ihe owuwu.
8. Hazie oge mmeghe
HPMC nwere ike gbanwee oge mmeghe nke ntụ ntụ putty. Oge mmeghe na-ezo aka n'oge a ga-edozi ntụ ntụ nke putty na mezie mgbe e wuchara ya. Site n'ịchịkwa ego nke HPMC agbakwunyere, oge mmeghe nke ntụ ntụ putty nwere ike ịgbatị ma ọ bụ dị mkpirikpi nke ọma iji mee mgbanwe maka mkpa ihe owuwu dị iche iche.
9. Meziwanye nkwụsị mgbape
N'ihi njupụta na njigide mmiri nke HPMC, ọ nwere ike igbochi uzuzu putty nke ọma ka ọ ghara ịdaba na mgbawa n'ihi oke mmiri na-efunahụ n'oge usoro ihicha. Ọ nwere ike inye mgbatị kwesịrị ekwesị, na-ekwe ka oyi akwa putty a mịrị amị guzogide nrụgide mpụga ma belata ihe omume nke mgbawa elu.
10. Meziwanye nguzogide ihu igwe
HPMC nwere ike ịkwalite nguzogide ihu igwe nke ntụ ntụ ma gbochie ịka nká na mmebi nke oyi akwa putty na gburugburu ebe siri ike. N'ihi ihe ndị na-emepụta ihe nkiri na nkwụsi ike nke HPMC, ọ nwere ike iguzogide mmebi nke ultraviolet na mgbanwe iru mmiri, na-agbatị ndụ ọrụ nke ntụ ntụ putty.
HPMC na-arụ ọtụtụ ọrụ na putty ntụ ntụ. Site na njigide mmiri, ịgbatị, na imepụta ihe nkiri iji kwalite arụmọrụ ihe owuwu na imezi mgbape mgbape, ọ na-arụ ọrụ dị mkpa na arụmọrụ na mmetụta nrụpụta nke putty powder. Ngwa ya na-eme ka ntụ ntụ putty nwee arụmọrụ ụlọ ka mma, nkwụsi ike na ogologo oge, na-enye nkwa dị mkpa maka mgbidi mgbidi. Na nkenke, HPMC bụ ihe dị mkpa na ihe dị mkpa nke putty ntụ ntụ ma na-arụ ọrụ na-enweghị ike dochie anya n'ịkwalite arụmọrụ zuru oke nke putty ntụ ntụ.
