Mmetụta dị aṅaa ka uzuzu polymer redispersible nwere na ike ngwa agha?

Ijikọ polymer powders redisspersible (RPP) n'ime ngwa ngwa na-emetụta nke ọma njirimara ike nke ihe na-esi na ya pụta.Edemede a na-enyocha mmetụta nke RPP na ike ngwa agha, gụnyere mmetụta ha na ike mkpakọ, ike mgbanwe, ike nrapado, na nguzogide mmetụta.

1. Ike mkpakọ:

Ike mkpakọ bụ ihe dị mkpa nke ngwa agha, na-egosi ike ya iguzogide ibu axial.Mgbakwunye RPP nwere ike ịkwalite ike mkpakọ site na ọtụtụ usoro:

Ọnụnọ na-abawanye:

Ndị RPP na-arụ ọrụ dị ka ihe na-ejikọta ọnụ, na-akwalite njikọ dị mma n'etiti ihe ngwa ngwa.Njikọ interparticle a ka mma na-enye aka na ike mkpakọ dị elu site n'ibelata oghere dị n'ime yana ịkwalite nguzosi ike n'ezi ihe nke ihe ahụ.

Mbelata mmịrị mmiri:

RPP na-eme ka njigide mmiri dị na ngwa agha, na-enye ohere maka hydration nke ọma nke ihe cimenti.Mmiri mmiri nke ọma na-eduga na obere microstructures dị ntakịrị na oghere ole na ole, na-ebute ike mkpakọ dị elu na ọnụ ọgụgụ mmịnye mmiri dị ala.

Ike Flexural emelitere:

Mgbanwe mgbanwe nke RPP na-enye nwere ike imetụta ike mkpakọ n'ụzọ na-apụtaghị ìhè site na igbochi microcracks ịgbasa na imebi ihe.Mortars nwere RPP na-egosipụtakarị ike mgbanwe dị mma, nke na-ejikọta ya na nguzogide nkwalite na ike mkpakọ.

2. Ike Flexural:

Ike mgbanwe na-atụ ike ihe nwere ike iguzogide ịgbagọ ma ọ bụ nrụrụ n'okpuru ibu etinyere.RPP na-atụnye aka n'ịkwalite ike mgbanwe na ngwa agha site na usoro ndị a:

Ike nkekọ abawanyela:

RPP na-eme ka adhesion dị n'etiti ngwa ngwa na ihe ndị dị n'elu ala, na-ebute njikọ siri ike ma belata delamination.Ike njikọ a emelitere na-atụgharị gaa na nguzogide dị elu na mgbada na nrụgide tensile, si otú a na-eme ka ike mgbanwe dị elu.

Njikọta emelitere:

Ngwongwo jikọrọ ọnụ nke ngwa agha agbanwere RPP na-enyere aka kesaa ibu etinyere n'otu n'otu n'ofe akụkụ ihe ahụ.Nkesa nke a na-ebelata oke nrụgide mpaghara ma gbochie ọdịda akaghi aka, na-ebute ike mgbanwe dị elu.

3. Ike nrapado:

Ike nrapado na-ezo aka na njikọ dị n'etiti ngwa agha na elu ala.RPP na-arụ ọrụ dị mkpa n'ịkwalite ike nrapado site na usoro ndị a:

Adhesion emelitere:

RPP na-akwalite nrapado ka mma site n'ịmepụta ihe nkiri dị gịrịgịrị, na-agbanwe agbanwe n'elu ala, nke na-eme ka mpaghara kọntaktị na-akwalite njikọ ihu.Nke a emelitere nrapado na-egbochi mwepu ma hụ na njikọ siri ike n'etiti ngwa agha na mkpụrụ.

Mgbawa Mbelata Mbelata:

Mgbanwe mgbanwe na ihe njide mmiri nke RPP na-enyere aka belata mbelata mgbawa na ngwa agha, nke nwere ike imebi ike nrapado.Site n'ibelata nguzobe mgbawa na mgbasa, RPP na-enye aka na njikọ nrapado siri ike ma na-adịgide adịgide.

4. Nguzogide mmetụta:

Nguzogide mmetụta na-atụ ikike ihe onwunwe iguzogide mmetụta ike dị elu na mberede na-enweghị mgbaji ma ọ bụ agbaji.RPP na-eme ka nkwụsi ike nke ngwa agha dịkwuo mma site na usoro ndị a:

Mgbabawanye ike:

ngwa agha emezigharịrị nke RPP na-egosipụta ike dị elu n'ihi mgbanwe mgbanwe ya na ductility.Mmụba siri ike a na-enye ohere ka ihe ahụ nweta ma wepụ ike mmetụta nke ọma, na-ebelata ohere nke mgbaji ma ọ bụ ọdịda na mmetụta.

Ọdịnaya emelitere:

Ịdị ogologo oge nke RPP na-enye na-agbatị ndụ ọrụ nke ngwa agha, na-ahụ na arụmọrụ ogologo oge n'okpuru ọnọdụ ndị siri ike.Ọdịgidere nke a na-eme ka ọ dịkwuo mma na-atụgharị na nguzogide dị elu maka mmebi mmetụta, abrasion, na ụdị nrụgide ndị ọzọ.

N'ikpeazụ, polymer powders redisspersible na-arụ ọrụ dị mkpa n'ịkwalite njirimara ike nke ngwa agha, gụnyere ike mkpakọ, ike mgbanwe, ike nrapado, na nguzogide mmetụta.Site na imeziwanye njikọta, nrapanye, na ịdịte aka, RPP na-enye aka n'ịmepụta ngwa agha dị elu nke dabara adaba maka ọtụtụ ngwa ihe owuwu.
