Na-ekwu banyere ọrụ nke redispersible latex ntụ ntụ dị iche iche ngwa agha

Na redispersible latex ntụ ntụ nwere ike ịgbasa ngwa ngwa n'ime emulsion mgbe ọ kpọtụrụ mmiri, ma nwee otu ihe onwunwe dị ka emulsion mbụ, ya bụ, ihe nkiri nwere ike ịmepụta mgbe mmiri ahụ kwụsịrị.Ihe nkiri a nwere nnukwu mgbanwe, elu ihu igwe na-eguzogide na iguzogide dị iche iche High adhesion na substrates.Tụkwasị na nke ahụ, uzuzu latex hydrophobic nwere ike ime ka ngwa agha ahụ bụrụ ihe na-adịghị mma.

A na-eji ntụ ntụ latex na-emegharị emegharị eme ihe na:

Ime na mpụga mgbidi putty ntụ ntụ, tile nrapado, tile na-atụ gị n'ụlọnga, akọrọ ntụ ntụ interface n'ụlọnga, mpụga thermal mkpuchi ngwa agha maka mpụga mgbidi, onwe-leveling ngwa agha, idozi ngwa agha, ji achọ ngwa agha, waterproof ngwa agha mpụga thermal mkpuchi akọrọ-agwakọta ngwa agha.N'ime ngwa agha ahụ, ọ bụ iji meziwanye brittleness, akwa na-agbanwe modul na adịghị ike ndị ọzọ nke ngwa ngwa ciment ọdịnala, na inye ciment ciment nke ọma na mgbanwe dị mma na ike njikọ ike, ka iguzogide na igbu oge ọgbọ nke ciment mortar cracks.Ebe ọ bụ na polymer na ngwa agha na-etolite usoro netwọk interpenetrating, a na-emepụta ihe nkiri polymer na-aga n'ihu na pores, nke na-eme ka njikọ dị n'etiti nchịkọta na-egbochi ụfọdụ pores na ngwa agha ahụ, ya mere, ngwa agha gbanwere mgbe ọ gbasịrị siri ike dị mma karịa ngwa ngwa ciment.Enwere nnukwu ọganihu.

Ọrụ nke ntụ ntụ latex na-agbanwe agbanwe na ngwa agha bụ nke kachasị n'akụkụ ndị a:

1. Melite ike mkpakọ na ike mgbanwe nke ngwa agha.

2. Mgbakwunye nke latex ntụ ntụ na-eme ka elongation nke ngwa agha ahụ dịkwuo elu, si otú ahụ na-eme ka mmetụta siri ike nke ngwa agha dịkwuo mma, ma na-enyekwa ngwa agha ahụ mmetụta dị mma nke mgbasa ozi nrụgide.

3. Melite arụmọrụ nke ngwa ngwa.Usoro njikọ ahụ na-adabere na mgbasa ozi na mgbasa nke macromolecules n'elu nnyapade.N'otu oge ahụ, latex ntụ ntụ nwere ụfọdụ permeability na n'ụzọ zuru ezu na-abanye n'elu ihe isi ihe na cellulose ether, nke mere na ihe ndị dị n'elu nke isi na plasta ọhụrụ dị nso, si otú ahụ na-emeziwanye Adsorption na-abawanye arụmọrụ ya.

4. Belata modul na-agbanwe nke ngwa agha, kwalite ikike nrụrụ ma belata ihe mgbawa.

5. Meziwanye ihe mgbochi nke ngwa agha.Ọganihu nke nguzogide iyi bụ tumadi n'ihi ịdị adị nke ụfọdụ nke gluu n'elu ngwa agha ahụ.Ntụ ntụ gluu na-arụ ọrụ dị ka njikọ, na usoro omentum nke ntụ ntụ gluu na-eme nwere ike gafere n'oghere na mgbawa na ngwa ngwa ciment.Na-eme ka njikọ dị n'etiti ihe isi na ngwaahịa hydration ciment, si otú ahụ na-abawanye nguzogide eyi.

6. Nye ngwa agha ahụ magburu onwe ya nguzogide alkali.

7. Meziwanye njikọta nke putty, nguzogide dị mma, nguzogide alkali, na-eyi nguzogide, ma welie ike na-agbanwe agbanwe.

9. Meziwanye njide mmiri nke putty, mee ka oge na-emeghe, ma melite arụmọrụ.

10. Meziwanye nguzogide mmetụta nke putty ma welie ike nke putty.

A na-eme ntụ ntụ latex na-emegharị emegharị site na emulsion polymer site na ihicha ịgba.Mgbe agwakọta ya na mmiri na ngwa ngwa, ọ na-emulsified na gbasasịa n'ime mmiri na-re-mepụta a kwụsiri ike polymer emulsion.Mgbe emechara ntụ ntụ latex redispersible ma gbasasịa n'ime mmiri, mmiri na-ekpochapụ.A na-emepụta ihe nkiri polymer na ngwa agha iji meziwanye ihe onwunwe nke ngwa agha.Uzuzu uzuzu latex dị iche iche nwere mmetụta dị iche iche na ngwa ngwa ntụ ntụ akọrọ.

Njirimara ngwaahịa nke ntụ ntụ latex redispersible

──Melite ike mgbada na ike mgbanwe nke ngwa agha

Ihe nkiri polymer kpụrụ site na redispersible polymer ntụ ntụ nwere ezigbo mgbanwe.A na-emepụta ihe nkiri n'ime oghere na elu nke simenti ngwa ngwa ngwa ngwa iji mepụta njikọ na-agbanwe agbanwe.Ngwa ngwa simenti dị arọ na nke na-agbaji agbawa na-aghọ ihe na-agbanwe.Mortar agbakwunyere ya na uzuzu latex na-agbanwe agbanwe dị elu ọtụtụ ugboro na nkwụsi ike na ngbanwe karịa ngwa ngwa nkịtị.

── Melite ike njikọ na njikọta nke ngwa agha

Mgbe ntụ ntụ latex redispersible dị ka ihe na-ekekọta organic ka emebere ka ọ bụrụ ihe nkiri, ọ nwere ike ịmepụta ike ike dị elu na ike njikọ dị iche iche.Ọ na-arụ ọrụ dị mkpa na ntinye nke ngwa agha na ihe ndị dị ndụ (EPS, bọọdụ ụfụfụ extruded) na ihe ndị dị n'elu ala.A na-ekesa ntụ ntụ polymer na-emepụta ihe nkiri na-ekesa n'ime usoro ngwa agha dị ka ihe na-eme ka ọ dịkwuo mma iji mee ka njikọ nke ngwa agha dịkwuo elu.

──Melite nguzogide mmetụta, ịdịte aka na iyi mgbochi nke ngwa agha

Ihe ndị dị na latex ntụ ntụ na-ejupụta oghere nke ngwa agha ahụ, njupụta nke ngwa agha na-abawanye, ma na-eme ka ihe mgbochi ahụ dịkwuo mma.N'okpuru omume nke ike mpụga, ọ ga-emepụta ntụrụndụ na-enweghị ebibi.Ihe nkiri polymer nwere ike ịdị na-adịgide adịgide na usoro ngwa agha.

── Melite nguzogide ihu igwe ma mee ka ngwa agha kwụsịlata, ma gbochie ngwa agha ka ọ ghara ịgbawa.

Redispersible latex ntụ ntụ bụ resin thermoplastic nwere ezigbo mgbanwe, nke nwere ike ime ka ngwa agha nagide mgbanwe nke oyi na-ekpo ọkụ na gburugburu ebe obibi, ma gbochie ngwa agha ahụ nke ọma n'ihi mgbanwe mgbanwe okpomọkụ.

── Meziwanye hydrophobicity nke ngwa agha ma belata mmịpụta mmiri

Na redispersible latex ntụ ntụ na-emepụta ihe nkiri na oghere na elu nke ngwa agha ahụ, na ihe nkiri polymer agaghị agbasa ọzọ mgbe ekpughere ya na mmiri, nke na-egbochi ntinye nke mmiri ma na-eme ka enweghị ike.Pụrụ iche redispersible latex ntụ ntụ nwere hydrophobic mmetụta, mma hydrophobic mmetụta.

── Melite workability nke ngwa agha na-ewu&

Enwere mmetụta mmanye mmanye n'etiti ihe ndị dị na polymer latex ntụ ntụ, nke mere na ngwa ngwa ngwa nwere ike ịgba ọsọ n'adabereghị.N'otu oge ahụ, uzuzu latex nwere mmetụta na-emepụta ihe na ikuku, na-enye mkpakọ ngwa ngwa ma na-eme ka arụ ọrụ nke ngwa agha dịkwuo mma.

Ngwa ngwaahịa nke uzuzu latex redispersible

1. Sistemụ mkpuchi mgbidi mpụga:

Ngwa ngwa nrapado: hụ na ngwa agha ahụ ga-ejikọta mgbidi ahụ na bọọdụ EPS.Melite ike nkekọ.

Ngwakọta plasta: hụ na ike igwe, mgbape mgbape, ịdịte aka na nguzogide mmetụta nke sistemu mkpuchi ọkụ.

2. Ihe nrapado tile na ihe na-eme ka ọ na-eme ihe:

Adhesive Tile: Na-enye njikọ dị elu na ngwa agha ahụ, na-enye ngwa agha ahụ mgbanwe zuru oke iji nabata ọnụọgụ dị iche iche nke mgbasawanye okpomọkụ nke mkpụrụ na taịlị.

Sealant: Mee ka ngwa agha ahụ nwee ezigbo enweghị ike ma gbochie ntinye mmiri.N'otu oge ahụ, ọ nwere ezigbo mmachi, obere shrinkage na mgbanwe na nsọtụ nke tile.

3. Nrụzigharị taịlị na plasta osisi putty:

Melite ike nchikota na ike njikọ nke putty na ihe ndị pụrụ iche (dị ka ihe dị n'elu tile, mosaics, plywood na ihe ndị ọzọ dị mma), ma hụ na putty nwere ezigbo mgbanwe iji mebie ọnụọgụ mgbasawanye nke mkpụrụ.

4. Putty maka mgbidi ime na mputa:

Melite ike njikọta nke putty wee hụ na putty nwere ụfọdụ mgbanwe mgbanwe iji chekwaa mgbasawanye na nrụgide dị iche iche nke ọkwa ntọala dị iche iche mepụtara.Gbaa mbọ hụ na putty nwere ezigbo nguzogide ịka nká, enweghị ike na mgbochi mmiri.

5. Ngwa agha ala na-ebuli onwe ya:

Gbaa mbọ hụ na ndakọrịta modulus na-agbanwe, nkwụchi na-ehulata na mgbape nke ngwa agha.Melite nguzogide iyi, ike njikọta na njikọta nke ngwa agha.

6. Ngwa ngwa ihu:

Meziwanye ike elu nke mkpụrụ ma hụ na adhesion nke ngwa agha ahụ dị.

7. Ngwa eji egbochi mmiri nke simenti:

Gbaa mbọ hụ na arụ ọrụ mgbochi mmiri nke mkpuchi ngwa agha, ma n'otu oge ahụ nwee ezigbo nrapado n'elu ala ala, ma melite ike mkpakọ na mgbanwe nke ngwa agha ahụ.

Asato, rụkwaa ngwa agha:

Gbaa mbọ hụ na ọnụọgụ mgbasawanye nke ngwa agha ahụ dabara na ihe ntọala wee belata modulus nke ngwa agha ahụ.Jide n'aka na ngwa agha ahụ nwere oke mmiri na-ezuru oke, ikuku ikuku na ike jikọtara ọnụ.

9. Ngwa eji akwa akwa:

Na-eme ka njide mmiri dịkwuo mma.

Belata mfu mmiri ka ọ bụrụ ihe ndị nwere porous.

Meziwanye ịdị mfe nke ịrụ ọrụ ihe owuwu ma melite arụmọrụ ọrụ.
