Methylhydroxyethylcellulose (MHEC) bụ ngwakọta polymer nke a na-ejikarị eme ihe na ihe owuwu ma nwee uru dị ukwuu na ngwa putty. Nke a bụ uru bụ isi nke methylhydroxyethylcellulose na ngwa putty:
1. Melite arụmọrụ ihe owuwu
1.1 Meziwanye njigide mmiri
Methyl hydroxyethyl cellulose nwere ezigbo njide mmiri, nke na-enyere aka ịgbatị oge oghere nke putty, na-enye ohere ka onye na-etinye oge na-eme mgbanwe na mmetụ aka. Tụkwasị na nke ahụ, njide mmiri dị mma na-egbochi putty ka ọ ghara ikpochapụ ngwa ngwa mgbe ngwa ngwa, na-ebelata ihe ize ndụ nke ịgbawa na chalking.
1.2 Mee ka mmiri na-arụ ọrụ rụọ ọrụ na ịrụ ọrụ
MHEC nwere ike imeziwanye mmiri nke putty nke ọma, na-eme ka ọ dị mfe itinye na ịgbasa. Nke a nwere ike ibelata akara ahịhịa na afụ n'oge usoro ihe owuwu ma melite ogo ihe owuwu na ihe ịchọ mma nke putty.
1.3 Nye ezigbo adhesion
MHEC nwere ike ime ka adhesion dị n'etiti putty na mkpụrụ, na-eme ka nkwụsi ike na ịdịte aka nke mkpuchi. Nke a dị mkpa karịsịa maka iwu ụlọ na gburugburu ebe dị mgbagwoju anya ma ọ bụ okpomọkụ dị elu, n'ihi na ọ na-egbochi oyi akwa putty ka ọ na-apụ ma wepụ ya.
2. Meziwanye ihe anụ ahụ nke putty
2.1 Kwalite nguzogide mgbape
N'ihi njigide mmiri na mmetụta plastik nke MHEC, putty nwere ike ịdaba n'oge usoro ihicha, na-ebelata ohere nke ihicha na ịgbawa. A na-emewanye mgbanwe nke putty, na-enye ya ohere ime mgbanwe nke ọma na obere nrụrụ dị na mkpụrụ na-enweghị mgbawa.
2.2 Melite nguzogide iyi
MHEC na-eme ka ike na ike nke putty dịkwuo mma, na-eme ka elu ya na-eguzogide ọgwụ. Nke a dị mkpa karịsịa maka mgbidi a na-ejikarị eme ihe ma ọ bụ na-enwe esemokwu, na-enyere aka ịgbatị ndụ mgbidi ahụ.
2.3 Melite nguzogide ihu igwe
MHEC na putty nwere ike imeziwanye nguzogide ihu igwe ya, na-enye ya ohere ịnọgide na-arụ ọrụ kwụsiri ike n'okpuru ọnọdụ ihu igwe dị iche iche. Ma ọ bụ okpomọkụ dị elu, obere okpomọkụ ma ọ bụ ebe iru mmiri, putty nwere ike ịnọgide na-enwe ọmarịcha anụ ahụ ya na mgbanwe gburugburu ebe obibi adịghị emetụta ya ngwa ngwa.
3. Na-ebuli nkwụsi ike kemịkalụ nke putty
3.1 Kwalite nguzogide alkali
Methyl hydroxyethyl cellulose nwere ike imeziwanye nguzogide alkali nke putty ma gbochie mmebi arụmọrụ kpatara site na mbuze site na ihe alkaline. Nke a na-eme ka o doo anya na putty na-ejigide ọrụ ya dị mma na ọdịdị ya mgbe ọ na-ejikọta ihe ndị nwere alkaline dị ka cementious substrates.
3.2 Mma antibacterial na antifungal Njirimara
MHEC nwere ụfọdụ antibacterial na mgbochi mildew mmetụta, nke nwere ike igbochi uto nke nje bacteria na ebu ma gbochie mildew ntụpọ na ísì ka ọ pụta ìhè n'elu putty. Nke a dị mkpa karịsịa na gburugburu iru mmiri ma ọ bụ iru mmiri iji nyere aka mee ka mgbidi dị ọcha na ịdị ọcha.
4. Nchekwa gburugburu ebe obibi na uru akụ na ụba
4.1 Njirimara nchedo gburugburu ebe obibi
Methyl hydroxyethyl cellulose bụ ihe na-acha akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi nke na-adịghị egbu egbu na nke na-adịghị emerụ ahụ mmadụ na gburugburu ebe obibi. Ojiji ya nwere ike ibelata iji ihe mgbakwunye kemịkalụ ndị ọzọ na-emerụ ahụ ma belata mmetọ gburugburu ebe obibi n'oge usoro ihe owuwu.
4.2 Belata ụgwọ
Ọ bụ ezie na ọnụahịa mbụ nke MHEC nwere ike ịdị elu, arụmọrụ ya dị irè na putty nwere ike ibelata ọnụ ọgụgụ nke ihe eji eme ihe na oge ntinye, si otú ahụ na-ebelata ụgwọ ọrụ ụlọ. Ogologo ndụ ọrụ na obere mmezi ihe na-ebutekwa uru akụ na ụba dị ogologo oge.
5. Nnukwu ngwa ngwa
Methyl hydroxyethyl cellulose abụghị naanị adabara maka mgbidi ime ụlọ, ma a na-ejikwa ya mee ihe n'ọtụtụ ihe eji arụ ụlọ dị ka mgbidi mgbidi mpụta, ngwa agha mgbochi na-agbaji, na ngwa agha na-ebuli onwe ya. Ọdịdị ya na ihe ndị magburu onwe ya na-eme ka ọ bụrụ ihe mgbakwunye dị mkpa na-ewu ụlọ nke oge a.
Methylhydroxyethylcellulose nwere uru dị ukwuu na ngwa putty. Site na imeziwanye njide mmiri, ihe owuwu ihe owuwu, adhesion na ihe anụ ahụ, MHEC nwere ike imeziwanye arụmọrụ ihe owuwu na ojiji nke putty. Tụkwasị na nke ahụ, ihe onwunwe ya na gburugburu ebe obibi na uru akụ na ụba na-emekwa ka ọ bụrụ ihe mgbakwunye ihe owuwu ụlọ dị mma. Site na mmepe nke teknụzụ owuwu na-aga n'ihu, atụmanya ngwa nke MHEC na putty ga-abawanye.
