Putty ntụ ntụ bụ ihe eji ewu ewu na-ewu ewu nke a na-eji akwa akwa na imezi mgbidi, elu ụlọ na ihe ndị ọzọ.Ọ bụ ngwakọta nke ihe dị iche iche dị ka ciment, filler na ihe nkedo.Hydroxypropylmethylcellulose (HPMC) bụ otu n'ime ihe eji ejikọta na ntụ ntụ.HPMC bụ polymer na-adịghị egbu egbu, na-esi ísì ụtọ nke na-eme ka arụ ọrụ nke ntụ ntụ putty dịkwuo mma.A na-eji ya na mgbawa na ụdị putty dị iche iche iji kwalite arụmọrụ ya.Isiokwu a ga-atụle ụdị anọ nke putty cracks na otu esi eji HPMC n'ụdị ọ bụla.
Ụdị ihe anọ nke putty cracks bụ ndị a:
1. Mbelata mgbawa
Mbelata cracks n'ihi akọrọ putty.Ka putty na-akpọnwụ, ọ na-ebelata, na-eme ka mgbawa pụta n'elu.Ogo nke cracks ndị a na-adabere na ihe mejupụtara nke putty.Enwere ike ịgbakwunye HPMC na putty iji belata mgbawa shrinkage.HPMC na-arụ ọrụ dị ka onye na-ejigide mmiri, na-ebelata usoro ihicha ma na-ekwe ka putty kpochaa nke ọma.Ọ na-ebelatakwa mmiri dị mkpa iji gwakọta putty, nke na-enyere aka belata mbelata n'oge ihicha.
2. Mgbawa na-ekpo ọkụ
A na-eme ka mgbawa ọkụ na-ekpo ọkụ site na mgbasawanye na nkwekọrịta nke ihe dị ka okpomọkụ na-agbanwe.A na-ahụkarị ha n'ụlọ ndị nwere nnukwu mgbanwe okpomọkụ, dịka n'ebe ndị nwere oke ihu igwe.HPMC nwere ike inye aka belata mgbawa ọkụ site n'ịbawanye ihe njide mmiri nke putties.Polymer na-arụ ọrụ dị ka ihe nkedo nke na-enyere aka ijide akụkụ ndị ọzọ nke putty ọnụ.Nke a na-ebelata ohere nke mgbawa n'ihi mgbasawanye okpomọkụ na nkwekọrịta.
3. Ịgba mgbawa
A na-akpata mgbawa siri ike site na ike siri ike nke putty.Ka putty na-esi ike, ọ na-efunahụ ụfọdụ mgbanwe ya, na-eme ka ọ gbawaa.HPMC nwere ike inye aka belata mgbawa mgbawa ike site n'ịbawanye mgbanwe nke putty.Nke a polymer na-arụ ọrụ dị ka plasticizer, na-eme ka putty na-agbanwe agbanwe.Nke a na-enye ya ohere iguzogide mmegharị nke elu a na-ese ya, na-ebelata ihe ize ndụ nke mgbawa.
4. Ihe mgbawa
Ọkpụkpụ ihe owuwu na-eme n'ihi mmegharị nke ihe owuwu ma ọ bụ n'okpuru ala.Enwere ike ịkpata ha site na ihe dị iche iche, dị ka ala ala ọma jijiji, ala ọma jijiji, ma ọ bụ mgbanwe nke mmiri dị n'elu.HPMC nwere ike inye aka belata mgbawa nhazi site na imeziwanye ihe nrapado nke putties.Polymer na-arụ ọrụ dị ka ihe nkedo, na-enyere putty aka ịrapagidesi ike n'elu.Nke a na-ebelata ohere nke mgbawa n'ihi mmegharị nke elu dị n'okpuru.
HPMC bụ ihe bara uru na ntụ ntụ n'ihi na ọ nwere ike inye aka melite arụmọrụ nke ụdị cracks dị iche iche.Site na ibelata ihe ize ndụ nke mbelata, ikpo ọkụ, ike siri ike na mgbawa nhazi, HPMC nwere ike inye aka hụ na putties adịru ogologo ma jigide ịma mma ha.Ka ụlọ ọrụ ihe owuwu na-aga n'ihu na-etolite, HPMC ka bụ ihe dị mkpa na ntinye maka ngwa ihe owuwu niile.
