Mgbe ị na-eme ma na-etinye ntụ ntụ ntụ, anyị ga-ezute nsogbu dị iche iche. Taa, ihe anyị na-ekwu bụ na mgbe a na-agwakọta ntụ ntụ ntụ na mmiri, ka ị na-emewanyewanye, otú ahụ ka ọ ga-adị gịrịgịrị, na ihe dị iche iche nke nkewa mmiri ga-adị njọ.
Ihe kpatara nsogbu a bụ na hydroxypropyl methylcellulose agbakwunyere na ntụ ntụ adịghị adabara. Ka anyị leba anya n'ụkpụrụ ọrụ yana otu anyị nwere ike isi dozie ya.
Ụkpụrụ nke putty ntụ ntụ na-adịwanye njọ ma dị nro:
1. A na-ahọrọ viscosity nke hydroxypropyl methylcellulose na-ekwesịghị ekwesị, viscosity dị oke ala, na mmetụta nkwụsịtụ ezughị oke. N'oge a, nkewa mmiri siri ike ga-eme, na mmetụta nkwụsịtụ otu agaghị egosipụta;
2. Tinye ihe na-eme ka mmiri dị na putty ntụ ntụ, nke nwere mmetụta dị mma na-ejigide mmiri. Mgbe putty na-agbaze na mmiri, ọ ga-ekpochi nnukwu mmiri. N'oge a, a na-atụgharị ọtụtụ mmiri n'ime ụyọkọ mmiri. Na ịkpali ọtụtụ mmiri na-ekewa, ya mere, a na-enwekarị nsogbu bụ na ka ị na-akpali akpali, na thinner ọ na-aghọ. Ọtụtụ ndị mmadụ enwetala nsogbu a, ị nwere ike belata nke ọma nke cellulose agbakwunyere ma ọ bụ belata mmiri agbakwunyere;
3. Ọ nwere njikọ ụfọdụ na nhazi nke hydroxypropyl methylcellulose ma nwee thixotropy. Ya mere, mgbe ịgbakwunye cellulose, dum mkpuchi nwere ụfọdụ thixotropy. Mgbe etinyere putty ngwa ngwa, usoro ya n'ozuzu ya ga-agbasa wee bụrụ nke na-adịchaghị mma ma dị gịrịgịrị, mana mgbe a hapụrụ ya, ọ ga-eji nwayọọ nwayọọ gbakee.
Ngwọta: Mgbe ị na-eji ntụ ntụ putty, na-agbakwunye mmiri na-akpali akpali iji mee ka ọ ruo ọkwa kwesịrị ekwesị, ma mgbe ị na-agbakwunye mmiri, ị ga-achọpụta na a na-agbakwunye mmiri karị, ọ na-adịwanye njọ. Gịnị kpatara nke a?
1. A na-eji cellulose mee ihe dị ka onye na-emepụta ihe na mmiri na-eme ka mmiri dị na putty ntụ ntụ, ma n'ihi thixotropy nke cellulose n'onwe ya, ihe mgbakwunye nke cellulose na putty ntụ ntụ na-edugakwa na thixotropy mgbe agbakwunyere mmiri na putty;
2. Nke a na-akpata thixotropy site na nbibi nke nhazi na-ejikọtaghị ọnụ nke ihe ndị dị na ntụ ntụ putty. A na-emepụta ihe owuwu a na izu ike ma gbasaa n'okpuru nrụgide, ya bụ, viscosity na-ebelata n'okpuru mkpali, na viscosity na izu ike Iweghachite, n'ihi ya, a ga-enwe ihe na-eme ka ntụ ntụ na-esi ísì na-aghọ nke dị ntakịrị ka ọ na-agbakwunye na mmiri;
3. Tụkwasị na nke ahụ, mgbe a na-eji uzuzu putty eme ihe, ọ na-akpọnwụ ngwa ngwa n'ihi na ntinye oke nke ntụ ntụ calcium na-ejikọta na nkụ nke mgbidi. Ntucha na ntụgharị nke ntụ ntụ putty metụtara ọnụ ọgụgụ njide mmiri;
4. Ya mere, iji zere ọnọdụ ndị na-adịghị mkpa, anyị ga-aṅa ntị na nsogbu ndị a mgbe anyị na-eji ya.
