Olee otú melite constructability nke cellulose na elu okpomọkụ mgbidi n'oge okpomọkụ

Ka ọ dị ugbu a, ọ na-achọ ịbanye n'oge okpomọkụ, na okpomọkụ dị oke elu, karịsịa na mpaghara ugwu.Okpomọkụ dị elu ma ikuku akpọnwụwo.Okpomọkụ dị n'elu mgbidi ahụ nwere ike iru 60 Celsius.N'ihi okpomọkụ, cellulose na-enwekarị nsogbu dị ka ụlọ na-adịghị mma na iwepụ ntụ ntụ n'oge a na-ewu ya.Isi ihe kpatara ya bụ na n'ihi oke okpomọkụ nke mgbidi ahụ, njide mmiri nke putty adịghị mma, n'ihi ya, mmiri dị na putty na-etinye ngwa ngwa ngwa ngwa ma ọ bụ kpochapu mgbidi ahụ, nke mere na a pụghị ịkwanye akwa ahụ ugboro ugboro ma kpoo ya.A na-enwe oghere na peeling.Otu esi emeziwanye njigide mmiri nke powdery mpụta mgbidi putty nwere ụzọ ndị a:

1. Mee ka ọnụọgụ cellulose ether dịkwuo elu

Cellulose ether nwere ezigbo njide mmiri, ma ọrụ njigide mmiri adịghị abawanye mgbe agbakwunyere ụfọdụ cellulose ether.N'otu oge ahụ, mmụba nke cellulose na-abawanye viscosity nke putty na ihe owuwu ahụ adịghị mma.Na mgbakwunye, ọnụ ahịa nke putty na-abawanye.

2. Mee ka ọnụ ọgụgụ nke lignocellulose dịkwuo elu

Lignocellulose nwere mmetụta njigide mmiri.Mgbakwunye nke eriri osisi na-eme ka ikike njigide mmiri dị mma, na-eme ka usoro ihe eji eme ihe na-eme ka ọ dịkwuo mma, ma nwee ike imeziwanye ọrụ n'otu oge ahụ, ma ụkpụrụ njide mmiri nke lignocellulose dị iche na nke cellulose.Ọ nwere njirimara nke ntinye ntutu.(Nduzi mmiri), a ga-enwe mmiri n'etiti eriri nke ọ bụla, na mgbe mmiri dị na gburugburu gburugburu nke eriri ahụ na-agbanwe ma na-ebelata, mmiri dị n'etiti eriri ga-ahapụ nke ọma.Oge imeghe, ọ dịghị mfe ịgbawa.Otú ọ dị, n'ihi na ọkpụrụkpụ nke putty na mgbidi dị n'èzí dị oke mkpa, ọkpụkpụ nke mkpuchi ọ bụla bụ naanị 0.5-1mm.Mgbe elu okpomọkụ nke isi oyi akwa na ikuku ikuku dị oke elu, ọrụ njigide mmiri ya adịghị egosi na ọ bụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ dị elu, na-arụ ọrụ mkpuchi mkpuchi ugboro ugboro bụ nkezi.

3. Mee ka ọnụọgụ polymer dịkwuo elu

Na mgbidi na thinner putty, akọrọ ikuku na elu isi okpomọkụ, na-amụba ego nke polymer bụ otu n'ime ụzọ kasị mma na-eme ka putty nwere ugboro scraping Njirimara, ma price nke redispersible latex ntụ ntụ dịtụ elu , nnukwu ego ga-amụba nke ukwuu. ego nke putty.Ọ nwekwara ike ịrụ ọrụ ka mma site n'ịgbakwụnye obere ntụ ntụ ntụ ntụ polyvinyl, ma viscosity nke polyvinyl mmanya ntụ ntụ dị ntakịrị, nke ga-emetụta ọrụ ọrụ, na ihe na-eme ka ájá nke putty adịghị mma..

4. Tinye mmanu polymer

Site na ule ahụ, a na-ewere ya na ọ bụ nhọrọ ka mma ịgbakwunye mmanu dị elu na ntinye mgbidi dị n'èzí na gburugburu ebe okpomọkụ dị elu n'oge okpomọkụ.Mmanu mmanu bụ nke polymer compound, na rheological mmanu bụ tumadi iji melite ewu arụmọrụ na ciment dabeere usoro.Oge mepere emepe na arụmọrụ na-agbanwe agbanwe.Na-abawanye ike ịrụ ọrụ na nguzogide sag nke ngwa agha, plasta, renders, plasters na adhesives ma gbochie delamination nke ciment na-edozi onwe ya.Ihe kpatara njide mmiri bụ na e nwere ọnụ ọgụgụ buru ibu nke ọrụ hydrophilic na agbụ molekụla ya.N'ihe banyere scraping na mkpuchi ugboro ugboro, ọ gaghị atụfu mmiri, nwere ọrụ njigide mmiri pụtara ìhè, ma nwee thickening na thixotropy n'otu oge ahụ, na-eme ka ihe owuwu ahụ dịkwuo nro ma nwee ike dochie cellulose nke ọma, mana ọnụahịa ya bụ naanị cellulose ether, na Usoro ọgwụgwọ ya bụ 0.1-0.2%., bụ ihe dị oke ọnụ ahịa, ọ bụrụ na ejiri ya na cellulose ether, lignocellulose, na redispersible latex powder, mmetụta ga-aka mma.
