RDP na VAE ntụ ntụ

RDP (Powder Polymer Redispersible) na VAE (Vinyl Acetate Ethylene) ntụ ntụ. Ka anyị nyochaa nke ọ bụla n'ime ha iche iche:

RDP (Ntụ ntụ polymer na-agbanwe agbanwe):

1. Nkọwa:

• RDP bụ ntụ ntụ ọcha na-asọ asọ nke enwetara site n'ịkpọsa emulsion polymer. Enwere ike ịgbasa ntụ ntụ nke na-esi na ya pụta na mmiri, na-eme ihe nkiri nke polymer mbụ.

2. Ihe mejupụtara:

• Ọ na-abụkarị polymer (dị ka vinyl acetate-etylene copolymer), colloid na-echebe, onye na-achụsa ihe, na mgbe ụfọdụ ihe mgbakwunye dị ka plasticizers ma ọ bụ thickeners.

3. Ngwa:

• A na-eji RDP eme ihe n'ọtụtụ ebe na ụlọ ọrụ ihe owuwu dị ka ihe mgbakwunye na ngwa ngwa mix mix, dị ka adhesives tile, ogige na-edozi onwe ya, na nrụzi ngwa agha. Ọ na-eme ka njirimara nke ihe ndị a dịkwuo mma, gụnyere adhesion, ike mgbanwe, na ịrụ ọrụ.

4. Ọrụ:

• Na-eme ka adhesion dị iche iche dị iche iche dịkwuo mma.
• Na-akwalite mgbanwe na deformability.
• Na-enye ike ijide mmiri.
• Na-akwalite iguzogide ihu igwe na ịka nká.
• Na-arụ ọrụ dị ka ihe nkedo iji melite akụrụngwa akụrụngwa nke ngwa agha.

5. Uru:

• Na-ebelata mgbawa na mbelata na ngwa agha.
• Na-eme ka ịdịte aka nke ihe owuwu a rụchara.
• Na-eme ka ikike ịrụ ọrụ na ngwa ngwa ngwa ngwa ngwa mix mix.

VAE (Vinyl Acetate Ethylene) ntụ ntụ:

1. Nkọwa:

• VAE ntụ ntụ bụ copolymer nke vinyl acetate na ethylene nke a na-emepụta n'ụdị ntụ ntụ. A na-enweta ya site n'ịkpọsa emulsion VAE.

2. Ihe mejupụtara:

• Ọ na-enwe vinyl acetate na ethylene copolymer, na-enwekarị mgbakwunye mgbakwunye iji welie ihe ndị a kapịrị ọnụ.

3. Ngwa:

• A na-ejikarị ntụ ntụ VAE eme ihe n'ịmepụta ihe nrapado, ihe mkpuchi, na ihe nkedo n'imepụta akwa akwa anaghị kpara akpa.

4. Ọrụ:

• Na-enye adhesion na adhesives na sealants.
• Na-arụ ọrụ dị ka ihe nkedo na textiles anaghị kpara akpa.
• Na-eme ka mgbanwe na elasticity dị iche iche na ngwa.

5. Uru:

• Na-enye ezigbo adhesion na mkpụrụ dị iche iche.
• Na-eme ka mgbanwe na ngbanwe dị na nhazi nrapado.
• Enwere ike iji ya mee ihe n'ụdị ngwa dị iche iche n'ihi ike ya.

Ntụnyere:

• Ihe jikọrọ:
  • Ma RDP na VAE ntụ ntụ sitere na emulsions ma na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu.
• Ojiji akọwapụtara
  • A haziri RDP kpọmkwem maka iji ya na ngwa ngwa mix mix, na-enye aka na nrapado na nrụnye ha.
  • ntụ ntụ VAE nwere ngwa sara mbara, gụnyere adhesives, sealants, na textiles anaghị kpara akpa.
• Ihe mejupụtara:
  • Ọ bụ ezie na ha abụọ na-agụnye vinyl acetate, RDP na-agụnyekarị ihe ndị ọzọ dị ka colloid nchebe, ndị na-achụsa ihe, na mgbe ụfọdụ ihe mgbakwunye.
• Ọrụ:
  • RDP na-ebute ụzọ na-arụ ọrụ nke ihe owuwu, na-elekwasị anya na adhesion, mgbanwe, na ogologo oge.
  • VAE ntụ ntụ na-eje ozi dị iche iche, gụnyere inye adhesion, na-eme dị ka ihe nkedo, na imeziwanye mgbanwe na ngwa dị iche iche.

Na nchịkọta, ma RDP na VAE ntụ ntụ bụ ihe bara uru na ngwa ha, na RDP bụ ọkachamara maka ngwaahịa ndị metụtara ihe owuwu, na VAE ntụ ntụ nwere ọtụtụ ngwa ngwa gụnyere adhesives, sealants, na textiles. Ọ bụrụ na ị nwere nkọwa ma ọ bụ ngwa n'uche, nweere onwe gị ịnye nkọwa ndị ọzọ maka nzaghachi ahaziri ahazi.
