Putty ntụ ntụ bụ ihe ewu ewu ewu eji emeju oghere, mgbawa na oghere dị n'elu tupu eserese ma ọ bụ tiling. Ihe mejupụtara ya bụ ntụ ntụ gypsum, ntụ ntụ talcum, mmiri na ihe ndị ọzọ. Agbanyeghị, putties emepụtara nke oge a nwekwara ihe mgbakwunye, hydroxypropyl methylcellulose (HPMC). Isiokwu a ga-atụle ihe mere anyị ji gbakwunye HPMC na ntụ ntụ putty na uru ọ na-eweta.
Hydroxypropyl methylcellulose bụ polymer soluble mmiri nke sitere na cellulose, bụ isi akụkụ nke mgbidi cell osisi. A na-eji ya na ụlọ ọrụ dị iche iche dịka ihe owuwu, ọgwụ, akwa na nri. N'ime ihe owuwu, a na-eji ya dị ka ihe eji eme ihe na ngwa agha, grouts, paints na putties.
Ịtinye HPMC na ntụ ntụ putty nwere uru ndị a:
1. Mụbaa njigide mmiri
HPMC bụ polymer hydrophilic nke na-amịkọrọ ma na-ejigide ụmụ irighiri mmiri. Ịtinye HPMC na ntụ ntụ putty nwere ike melite arụmọrụ njide mmiri ya. N'oge a na-arụ ọrụ, ntụ ntụ nke a gwakọtara na HPMC agaghị akpọnwụ ngwa ngwa, na-enye ndị ọrụ oge zuru oke iji jikwaa ihe ahụ ma mejupụta oghere nke ọma n'emeghị ka ihe ahụ gbawaa ma ọ bụ daa. Tinyere njide mmiri na-abawanye, ntụ ntụ na-ejikọta nke ọma na elu, na-ebelata ohere nke ịgbawa ma ọ bụ bee.
2. Melite ịrụ ọrụ
Putty ntụ ntụ na-agwakọta ya na HPMC ka ọ na-etolite nhịahụ dị ka tapawa, na-eme ka ọ dị mfe itinye ma gbasaa n'elu elu. HPMC na-enye ntụ ntụ putty ka ọ dị nro, na-enye mmecha nke ọma mgbe eserese ma ọ bụ tiling. Ọ na-enyekwa putty uru mkpụrụ dị elu, ikike iguzogide nrụrụ n'okpuru nrụgide. Nke a pụtara na e nwere ike ịkpụzi ntụ ntụ ntụ ntụ na HPMC n'ụzọ dị mfe ma kpụzie ya ka ọ dabara n'elu ala dị iche iche.
3. Belata mbelata na mgbawa
Dịka e kwuru na mbụ, HPMC nwere ike melite njigide mmiri nke ntụ ntụ putty. N'ihi nke a, putty ntụ ntụ na-adịkarịghị ka ọ ga-akpọnwụ ngwa ngwa mgbe etinyere ya n'elu, na-akpata mbelata na mgbawa. HPMC na-enyekwara aka ibelata mbelata na mgbawa n'ihi na ọ na-eme ka ike njikọ nke ntụ ntụ na-eme ka ihe ahụ kwụsie ike ma ghara ịdaba na mgbawa.
4. Mma iguzogide mmiri na mgbanwe okpomọkụ
The putty ntụ ntụ agwakọta na HPMC nwere mma iguzogide mmiri na okpomọkụ mgbanwe karịa putty ntụ ntụ na-enweghị HPMC. HPMC bụ polymer hydrophilic nke na-echebe ntụ ntụ site na mgbanwe okpomọkụ na iru mmiri. Nke a pụtara na ntụ ntụ nke agwakọta ya na HPMC na-adịte aka ma nwee ike iguzogide ọnọdụ ihu igwe dị iche iche.
5. Ogologo ndụ ogologo
Ịtinye HPMC na ntụ ntụ putty nwere ike ịgbatị ndụ nchekwa ya. HPMC na-egbochi ntụ ntụ putty ka ọ ghara ịnwụ ma sie ike n'oge nchekwa. Nke a pụtara na etinyere ntụ ntụ na HPMC nwere ike ịchekwa ogologo oge n'ebughị ibu ma ọ bụ bụrụ nke a na-apụghị iji ya mee ihe.
N'ịchịkọta, ịgbakwunye HPMC na putty ntụ ntụ nwere ọtụtụ uru. Ọ na-abawanye njide mmiri, na-eme ka usoro nhazi ahụ dịkwuo mma, na-ebelata mbelata na mgbawa, na-enye nguzogide mmiri na mgbanwe okpomọkụ ka mma, na-agbatị ndụ ndụ. Uru ndị a niile na-ahụ na ntụ ntụ nke agwakọta ya na HPMC ga-emecha nke ọma ma na-adịgide adịgide. Dị ka nke a, ọ bụ ihe dị mkpa na-enye aka na ihe ịga nke ọma nke ọrụ owuwu ọ bụla.
N'ozuzu, ojiji nke HPMC na putty powders bụ ezigbo mmepe maka ụlọ ọrụ ihe owuwu. Ọ na-enye ọtụtụ uru na-enyere aka mee ka ọrụ onye ọ bụla dị mfe, dị irè na ịrụ ọrụ nke ọma. Iji ya na-aga n'ihu nwere ike iduga n'ọhụụ ndị ọzọ nke na-emewanyewanye ogo ihe owuwu ụlọ na omume ụlọ.
