Ọrụ HPMC n'ụdị Putty

Hydroxypropyl methyl cellulose (HPMC) na-arụ ọrụ dị mkpa na nhazi putty ọgbara ọhụrụ ma a na-ewere ya dị ka ihe mgbakwunye ọrụ dị mkpa maka imeziwanye arụmọrụ, nkwụsi ike, na ịrụ ọrụ ogologo oge nke ihe mmecha mgbidi. Ma ejiri ya n'ime ma ọ bụ n'èzí putty, HPMC na-eme ka rheology, njide mmiri, mma mkpuchi, na ogologo oge. Ọrụ ya nwere ọtụtụ akụkụ na-eme ka ọ bụrụ akụkụ bụ isi na sistemu ngwakọta akọrọ nke sitere na ciment, gypsum, ma ọ bụ polymer binders.

1. Njide mmiri: Ọrụ mbụ na Putty Systems

Putty ga-enwerịrị mmiri zuru oke n'oge a na-agwọ ya iji hụ na hydration kwesịrị ekwesị nke ciment ma ọ bụ imepụta ihe nkiri zuru oke nke polymers. HPMC na-eme ka ikike njigide mmiri dịkwuo mma n'ihi usoro ihe omimi nke hydrophilic na ike imepụta ihe nkiri.

1.1.Uru nke njigide mmiri emelitere gụnyere:

Na-egbochi ihicha oge akaghi aka: Na-egbochi mgbawa, ịta nzu, ma ọ bụ ntụ ntụ n'ime ihe na-ekpo ọkụ, ikuku na-eku ma ọ bụ nke na-adọrọ adọrọ.

Ịkwado hydration ihe nkedo: Mmiri zuru oke na-enye ohere ka simenti ma ọ bụ gypsum mezue hydration, nke na-eme ka ike sie ike na nrapado.

Ịkwalite ire ụtọ ihe owuwu: Mmiri zuru oke na-agbatị oge oghere, na-eme ka ọ dị nro na-enweghị ịdọrọ akara.

1.2. Mmetụta usoro onunu ogwu:

0.2-0.5% HPMC nwere ike ibuli ọnụego njide mmiri nke putty karịa 95%, na-enyere aka nweta ọgwụgwọ kwụsiri ike ọbụlagodi na ọnọdụ gburugburu ebe obibi siri ike.

2. Mgbanwe Rheology na Omume ịdị arọ

Ọrụ ọzọ dị mkpa nke HPMC na nhazi nke putty bụ njikwa rheology. Ọ na-edozi viscosity, plasticity, na sag resistance nke tapawa mmiri, na-eme ka ngwa dị mfe na nrapado kwụsiri ike n'elu elu kwụ ọtọ.

2.1.Ntụnye aka ngụsị akwụkwọ:

Mmalite viscosity: Gbaa mbọ hụ na ngwakọta ahụ nwere ahụ zuru oke iji gbasaa n'otu.

Arụmọrụ mgbochi sag: Na-egbochi putty ka ọ ghara ịda, ọkachasị n'ime ngwa buru ibu ma ọ bụ n'elu ụlọ.

Ịgbasa uwe: na-eme ka mmetụta mma dịkwuo mma, na-enye ohere ka ọ dị nro, na-emecha n'elu.

Ọdịdị steeti mmiri kwụsiri ike: Na-egbochi ikewapụ ma ọ bụ ọbara ọgbụgba nke tapawa.

2.2. Ịhọrọ akara viscosity ziri ezi:

30,000-60,000mPa·s: Kwesịrị ekwesị maka putty ọkọlọtọ

75,000-100,000mPa·s: Kwesịrị ekwesị maka nnukwu sag-eguzogide ma ọ bụ mpụta putty formulations

Viscosity ziri ezi na-eme ka nguzozi dị n'etiti ịdị mfe nke ịgbasa na nrapado kwụsiri ike na mgbidi.

3.Ịrụ ọrụ na arụmọrụ ngwa emelitere

Ịrụ ọrụ bụ otu n'ime nchegbu ndị ọrụ mbụ na ngwaahịa putty. HPMC na-enye mmanu mmanu na nkwekọ dị larịị, na-eme ka ihe dị mfe maka ndị na-achọ ihe iji.

3.1.Mmalite ịrụ ọrụ gụnyere:

Mmanya emelitere: Trowel na-aga nke ọma n'ejighị arapara, na-ebelata ike ọgwụgwụ onye ọrụ.

Nhazi ka mma: Na-eme ka mbara ala dị larịị, nke edo edo dị njikere maka eserese ma ọ bụ akwụkwọ ahụaja.

Oge mepere emepe agbatịkwuru: Na-enyekwu oge iji dozie na mezie elu n'oge ngwa.

Mbelata ngwá ọrụ ịdọrọ: Ọ bara uru karịsịa na gburugburu okpomọkụ dị elu ma ọ bụ na-ekpo ọkụ ngwa ngwa.

Nkwalite ndị a na-akwalite arụmọrụ ụlọ yana afọ ojuju onye ọrụ.

4. Njide ike na elu iguzosi ike n'ezi ihe

Ọ bụ ezie na HPMC abụghị ihe nrapado mbụ, njide mmiri ya na ikike imepụta ihe nkiri na-eme ka ike njikọ dị n'etiti putty na mkpụrụ.

4.1.Uru na adhesion gụnyere:

Mmiri mmiri nke ọma na-eme ka njikọ siri ike dịkwuo n'etiti ihe simenti na mgbidi.

Ihe nkiri HPMC na-enye aka na njikọta elu, na-egbochi uzuzu na ntụ ntụ nke oyi akwa a gwọrọ.

Nguzozi nke mmiri kwụsiri ike na-ebelata mbelata, na-ebelata ihe egwu dị egwu.

elu mmiri nwere mmiri nke ọma na-ebute isi ike dị elu, nrapagidesi ike ka mma, yana ogologo oge.

5. Ọganihu mepere emepe yana ịrụ ọrụ n'okpuru ọnọdụ siri ike

Ọnọdụ gburugburu ebe obibi nwere mmetụta dị ukwuu na ọgwụgwọ putty. HPMC na-enyere aka hụ na arụmọrụ na-agbanwe agbanwe ọbụlagodi na ihu igwe siri ike.

5.1.Uru arụmọrụ:

Okpomọkụ dị elu: na-ebelata evaporation nke mmiri ma gbochie ịmepụta ihe nkiri mbụ.

Obere iru mmiri: Na-edobe nkwụsi ike na-arụ ọrụ ruo ogologo oge.

Gburugburu ikuku na-eku: na-ebelata mbelata akọrọ na ihe egwu na-agbawa.

Nkwụsi ike a dị mkpa karịsịa maka mpụta putty ma ọ bụ gburugburu ebe na-ehicha ngwa ngwa ebe nsogbu dị mma na-ebilitekarị.

6. Ịkwalite Nkwụsi ike nke Ụdị ntụ ntụ

Na akọrọ- mix putty, imezu arụmọrụ kwụsiri ike mgbe nchekwa ogologo oge dị oke mkpa. HPMC na-akwado nkwụsi ike a site na:

Na-emeziwanye ịdị n'otu nke ntụ ntụ

Na-egbochi nkewa nke ihe ndochi, ciment na ihe mgbakwunye

Na-edobe viscosity na-agbanwe agbanwe mgbe nchekwa

Ịkwaliteghachi mgbasawanye mgbe a na-agbakwunye mmiri

Nke a na-eme ka ndị ọrụ nwee ike ịnweta ngwakọ agwakọta na nsonaazụ ngwa ọbụlagodi mgbe ọnwa nke nchekwa gachara.

7. Aro usoro onunu ogwu maka nhazi Putty

Usoro onunu a chọrọ dabere n'ụdị mkpụrụ, ọnọdụ gburugburu ebe obibi, yana ihe achọrọ ịrụ ọrụ.

Ntuziaka izugbe (site n'ịdị arọ nke ngwakọta akọrọ):

Ime ụlọ: 0.2-0.4%

Putty nke mputa: 0.3-0.5%

Mpaghara na-arụ ọrụ dị elu ma ọ bụ iru mmiri dị elu: 0.4-0.6%

HPMC viscosity dị elu nwere ike ikwe ka usoro onunu ogwu dị ala n'ihi nrụpụta siri ike siri ike.

HPMC na-arụ ọrụ dị mkpa na arụmọrụ na ịdị mma nke usoro putty nke oge a. Ọrụ ndị bụ isi ya--gụnyere njide mmiri, njikwa rheology, arụ ọrụ ka mma, njigide elu, na nkwụsi ike ihe owuwu--na-emetụta ma afọ ojuju ngwa ngwa yana ogologo oge elu ogologo oge. Site na-ahọpụta ndị kwesịrị ekwesị viscosity ọkwa na onunu ogwu, emepụta nwere ike budata welie larịị arụmọrụ, mgbape eguzogide, nchekwa kwụsie ike, na mkpokọta finishing àgwà putty ngwaahịa. Dị ka ihe owuwu teknụzụ na-amalite, HPMC ga-anọgide na-abụ ihe mgbakwunye ntọala, na-enye ihe ngwọta dị elu nke mgbidi imecha n'ofe ime na ngwa.
