Putity bụ ihe dị mkpa ụlọ eji eme ihe maka elu mgbidi, arụmọrụ ya na-emetụta ngwakọta nke agba na ogo owuwu. Na usoro nke Putty, ihe mgbakwunye na-eli ozu na-arụ ọrụ dị mkpa.Hydroxypylththththththylcelllose (hpmc), dị ka otu n'ime ndị na-eme ihe eji eme ihe akpọrọ, nwere ike ime ka ọhụụ viccosity, arụmọrụ owuwu na nchekwa nke Putty.
1. Njirimara nke ihe eji eme ihe eji eme ihe
HPMC bụ mmiri na-abụghị nke ionic na ezigbo nke polymer na ezigbo thinning, nsị mmiri, mgbasa mmiri, emulsification na ihe na-akpụ akpụ ihe nkiri. Visaty na-emetụta ogo ya, ogo polymerization na ọnọdụ ndọlite. Ngwọta osisi nke na-eme ka ọ bụrụ ihe ngosi nke mmiri pseudoplastic, ya bụ, ọnụego awụda na-abawanye, nke dị oke mkpa maka owuwu nke Putty.
2. Mmetụta HPMC na Putty Visaty
2.1 mmetụta
HPMC na-etolite usoro viscosit site na mmiri. Mmetụta mmetụta ya na-egosipụtakarị n'akụkụ ndị a:
Mee ka ThixOpy nke Putty: HPMC nwere ike idobe putty dị elu ma ọ bụ ịnọgide na-ezere ọhụụ ma na-scraption arụmọrụ.
Idowanye oru nke PUTTY: Ozo nke HPMC nwere ike ime ka onu ogugu nke Putty, na-eme ka ihe na - emebi ihe.
Na-emetụta ike ikpeazụ nke Putty: mmetụta nke Hpmc na-eme ka oghere na centriging ihe ndị a na-ekesa na Puyety na-agbasasị ma melite arụmọrụ ike mgbe owuwu.
2.2 Mmetụta na usoro hydration
HPMC nwere ezigbo ihe eji egbochi mmiri, nke nwere ike belata mmiri dị na ube, si otú dị obere nke Pụrụ apịtị ma melite ike na ndagide na-emegide ya. Agbanyeghị, vissity dị elu nke HPMC ga-emetụta ikuku ikuku na ọsọ ọsọ nke Putty, na-ebute oke arụmọrụ. Ya mere, ego nke HPMC kwesịrị iji hụ na ọrụ ọrụ mgbe ị na-ezere mmetụta dị egwu na oge ịgbachi obi.
2.3 Mmekọrịta dị n'etiti oke molecular nke hpmc na viscosity nke putty
Nke dị elu molecular arọ nke Hpmc, nke viscosity nke ihe o mere. Na Putty, ojiji nke HPMC Oke Visaty (dị ka ụdị nke viscosity dị ka MPACH) nwere ike ime ka njigide mmiri dị mma na ngwakọta nke Putty, mana ọ nwekwara ike iduga na mbelata . Ya mere, n'okpuru ihe owuwu dị iche iche, HPMC na viscosity viscosity kwesịrị ekwesị iji belata njigide mmiri, ọrụ na arụmọrụ ikpeazụ.
2.4 Mmetụta HPMC DOSEAG na Putty Visaty
Onu ogugu nke Nchegbu na-egosiputa ihe di nkpa na viscosity nke Putty, na usoro onunu ogwu na-abụkarị n'etiti 0.1% na 0.5%. Mgbe usoro HPMC dị ala, mmetụta ndị na-emekarị na Putaty a pere mpe, ọ nwere ike ọ gaghị enwe ike ime ka ọrụ na mmiri na-eme ka ọrụ dị ike ka mma. Mgbe usoro ọgwụgwọ dị oke elu, viscosity nke Putity karịrị nnukwu, nguzobe owuwu na-abawanye, ọ nwere ike imetụta ọsọ ọkụ nke Putty. Yabụ, ọ dị mkpa ịhọrọ hpmc dị ka usoro nke Puntty na gburugburu ebe obibi.
Hydroxypyl Methylcelllose na-arụ ọrụ na tebuning, njigide mmiri na imezi ọrụ na Putty. Oke molecular, ogo nke dochie ma tinye ego nkeHpmcga-emetụtakwa vioty nke Putity. Onwe nke HPMC kwesịrị ekwesị nwere ike ime ka arụ ọrụ na mgbochi mmiri nke Putty, ebe a na-enwe oke mgbakwunye nwere ike ịbawanye ihe isi ike. Ya mere, na ezigbo ihe nke Putty, njirimara viscosit na ihe owuwu HPMC kwesịrị ịtụle, a ga-edozi usoro ahụ n'ụzọ ziri ezi iji nweta arụmọrụ kachasị mma na ogo ikpeazụ.
