Mgbe anyị na-eme ma na-etinye ntụ ntụ putty, anyị ga-enwe nsogbu dị iche iche. Taa, ihe anyị na-ekwu maka ya bụ na mgbe a gwakọtara ntụ ntụ putty na mmiri, otú ahụ ka ị na-agwakọta ntụ ntụ ahụ, otú ahụ ka putty ahụ ga-adị gịrịgịrị, ihe a na-akpọ nkewa mmiri ga-adịkwa njọ.
Isi ihe kpatara nsogbu a bụ na hydroxypropyl methylcellulose etinyere na ntụ ntụ putty adịghị mma. Ka anyị leba anya n'ụkpụrụ ọrụ na otu anyị ga-esi dozie ya.
Ụkpụrụ nke ntụ ntụ putty na-eme ka ọ dị gịrịgịrị ma dị gịrịgịrị:
1. A họrọghị viscosity nke hydroxypropyl methylcellulose nke ọma, viscosity ahụ dị oke ala, mmetụta nkwụsịtụ ahụ ezughịkwa oke. N'oge a, nkewa mmiri ga-adị oke njọ, mmetụta nkwụsịtụ ahụ agaghịkwa apụta ìhè;
2. Tinye ihe na-ejide mmiri na ntụ ntụ putty, nke nwere mmetụta dị mma na-ejide mmiri. Mgbe putty na mmiri gbazere, ọ ga-akpọchi nnukwu mmiri. N'oge a, ọtụtụ mmiri na-agbakọta n'ime otu ìgwè mmiri. Mgbe a na-akpali ọtụtụ mmiri, a na-ekewapụ ha, yabụ nsogbu a na-enwekarị bụ na ka ị na-agwakọta ya, otú ahụ ka ọ na-adị gịrịgịrị. Ọtụtụ mmadụ ezutela nsogbu a, ị nwere ike ibelata ọnụọgụ cellulose agbakwunyere ma ọ bụ belata mmiri agbakwunyere;
3. O nwere njikọ ụfọdụ na nhazi hydroxypropyl methylcellulose ma nwee thixotropy. Ya mere, mgbe etinyere cellulose, mkpuchi ahụ dum nwere thixotropy ụfọdụ. Mgbe a kpalitere putty ngwa ngwa, nhazi ya niile ga-agbasa ma dị gịrịgịrị ma dị gịrịgịrị, mana mgbe a hapụrụ ya ka ọ dị jụụ, ọ ga-agbake nwayọ nwayọ.
Ngwọta: Mgbe ị na-eji ntụ ntụ putty, na-etinyekarị mmiri ma gwakọta ya ka o ruo n'ọkwa kwesịrị ekwesị, mana mgbe ị na-etinye mmiri, ị ga-achọpụta na ka a na-etinyekwu mmiri, otú ahụ ka ọ na-adị gịrịgịrị. Gịnị kpatara nke a?
1. A na-eji cellulose eme ihe dị ka ihe na-eme ka mmiri sie ike ma na-ejide mmiri na ntụ putty, mana n'ihi thixotropy nke cellulose n'onwe ya, mgbakwunye nke cellulose na ntụ putty na-edugakwa na thixotropy mgbe etinyere mmiri na putty;
2. A na-akpata thixotropy a site na mbibi nke nhazi nke ihe ndị dị na ntụ ntụ putty. A na-emepụta nhazi a mgbe ọ na-ezu ike ma na-agbaji ya n'okpuru nrụgide, ya bụ, viscosity na-ebelata mgbe ọ na-akpali, na viscosity na ezumike Mgbake, yabụ a ga-enwe ihe merenụ na ntụ ntụ putty na-adị gịrịgịrị ka a na-agbakwunye ya na mmiri;
3. Na mgbakwunye, mgbe a na-eji ntụ ntụ putty eme ihe, ọ na-akpọnwụ ngwa ngwa n'ihi na mgbakwunye oke ntụ ntụ calcium na-emetụta nkụ nke mgbidi ahụ. Mkpụcha na mkpụgharị nke ntụ ntụ putty metụtara ọnụego njigide mmiri;
4. Ya mere, iji zere ọnọdụ ndị na-adịghị mkpa, anyị ga-elebara nsogbu ndị a anya mgbe anyị na-eji ya.
