Cellulose ethers|Ntụ ntụ polymer na-agbanwe agbanwe

Cellulose ethersna Redispersible Polymer Powder (RPP) bụ ụdị ihe abụọ dị iche iche, nke ọ bụla nwere ihe onwunwe na ngwa nke ya.Ka anyị nyochaa udi otu ọ bụla:

Cellulose ethers:

1. Nkọwa:

• Cellulose ethers bụ ezinụlọ nke polymers soluble mmiri nke sitere na cellulose, polymer eke dị na mgbidi cell osisi.

2. Ụdị:

• Ụdị cellulose ethers ndị a na-ahụkarị gụnyere Methyl Cellulose (MC), Hydroxyethyl Cellulose (HEC), Hydroxypropyl Cellulose (HPC), na Hydroxypropyl Methylcellulose (HPMC).

3. Ngwongwo:

• Solubility na mmiri: Cellulose ethers na-abụkarị mmiri soluble, na-akpụ gels transperent.
• Viscosity: Ha nwere ike gbanwee viscosity nke ngwọta, na-eme ka ha dị mma maka ngwa dị iche iche.
• Ịme ihe nkiri: Ọtụtụ cellulose ethers nwere ihe na-emepụta ihe nkiri.

4. Ngwa:

• Ọgwụ: A na-eji ya dị ka ihe na-ekekọta, ndị na-ekesa, na ihe mkpuchi ihe nkiri n'ụdị mbadamba.
• Ihe owuwu: A na-arụ ọrụ na ngwa ngwa, simenti, na nrapado tile maka ịrụ ọrụ na nrapanye ka mma.
• Ụlọ ọrụ nri: A na-eji ya dị ka ndị na-agbapụta ihe na ihe nkwụsi ike na ngwaahịa nri dị iche iche.
• Ngwaahịa Nlekọta Onwe Onye: Achọtara na ihe ịchọ mma, lotions, na shampoos maka ihe na-eme ka ha sie ike na nkwụsi ike.

Ntụ ntụ Polymer Agbanwegharị (RPP):

1. Nkọwa:

• Redispersible Polymer Powder bụ n'efu, ntụ ntụ ọcha nke mejupụtara ihe nkedo polymer jikọtara ya na mgbakwunye na ihe ndochi.

2. Ihe mejupụtara:

• A na-eme ya site na emulsions polymer (dị ka vinyl acetate-etylene copolymers) nke a na-efesa nke a mịrị amị iji mepụta ntụ ntụ.

3. Ngwongwo:

• Mgbanwe nke mmiri: RPP nwere ike ịgbasa n'ime mmiri iji mepụta ihe nkiri, dị ka emulsion polymer mbụ.
• Adhesion: Na-enye ntinye na mgbanwe na ngwa agha, ciment, na ihe ndị ọzọ owuwu.
• Nhazi ihe nkiri: Nwere ike ịmepụta ihe nkiri na-ejikọta ọnụ na nke na-agbanwe agbanwe mgbe ihicha.

4. Ngwa:

• Ụlọ ọrụ ihe owuwu: A na-eji ya eme ihe na tile adhesives, cement-based renders, and self-level compounds iji meziwanye adhesion, mgbanwe, na nkwụsị mmiri.
• Mortars na Renders: Na-akwalite akụrụngwa dị ka ịrụ ọrụ, ịdịte aka, na nrapado.
• Agba na mkpuchi: Enwere ike iji ya mee ihe na eserese ụlọ na mkpuchi maka ime mgbanwe na mmachi.

Ọdịiche:

• Solubility:
  • Cellulose ethers bụ n'ozuzu mmiri-soluble.
  • RPP anaghị amị amị na mmiri mana ọ nwere ike ịgbasa na mmiri ka ọ mepụta ihe nkiri.
• Mpaghara ngwa:
  • Cellulose ethers nwere ngwa dị iche iche na ọgwụ, nri, na nlekọta onwe onye, ​​na mgbakwunye na owuwu.
  • A na-ejikarị RPP eme ihe na ụlọ ọrụ ihe owuwu maka imeziwanye ihe nke ngwa agha, ciment na mkpuchi.
• Ngwakọta kemịkalụ:
  • A na-enweta ethers cellulose site na cellulose, polymer eke.
  • A na-eme RPP site na emulsion polymer sịntetik.

Na nchịkọta, mgbe cellulose ethers bụ mmiri-soluble polymers na dị iche iche ngwa, Redispersible Polymer ntụ ntụ bụ a na-abụghị mmiri soluble ntụ ntụ na-eji bụ isi na-ewu ụlọ ọrụ welie Njirimara nke ihe owuwu.Ha na-eje ozi dị iche iche ma na-ahọrọ dabere na ụfọdụ ngwa chọrọ.
