Kedu ka ọ dị mkpa ịgbakwunye ntụ ntụ polymer redispersible na drymix ngwa agha?

Polima ntụ ntụ redispersible bụ a fesa-akpọnwụ ntụ ntụ nke polima emulsion dabeere naethylene-vinyl acetate copolymer. Ọ bụ ihe dị mkpa na ngwa ngwa drymix nke oge a. Kedu mmetụta ndị ahụpolymer ntụ ntụ redispersiblenwere na ngwa agha ụlọ?

Ihe ndị na-emepụta ihe na-emepụta ihe na-emepụta polymer na-ejupụta oghere nke ngwa agha ahụ, njupụta nke ngwa agha na-abawanye, ma na-eme ka nguzogide eyi dịkwuo mma. N'okpuru omume nke ike mpụga, ọ ga-emepụta ntụrụndụ na-enweghị ebibi. Enwere ike ịchekwa ihe nkiri polymer na-adịgide adịgide na usoro ngwa agha.

1. Melite ịrụ ọrụ nke ihe owuwu ngwa ngwa

Mgbe uzuzu latex redispersible dị ka ihe na-eke ihe na-emepụta ihe na-eme ka ọ bụrụ ihe nkiri, ọ nwere ike ịmepụta ike dị elu na ike jikọtara ọnụ na ihe dị iche iche. 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. A na-ekesa ntụ ntụ na-emepụta ihe nkiri polymer n'ime usoro ngwa agha dị ka ihe na-eme ka ọ dịkwuo mma iji mee ka njikọ nke ngwa agha dịkwuo elu.

2. Meziwanye nguzogide ihu igwe, nkwụsi ike ifriizi na mgbape mgbape nke ngwa agha

Redispersible polymer ntụ ntụ bụ thermoplastic resin na ezi mgbanwe, nke nwere ike ime ka ngwa agha na-anagide mgbanwe nke mpụga oyi na-ekpo ọkụ na gburugburu ebe obibi, na n'ụzọ dị irè na-egbochi ngwa agha si cracking n'ihi mgbanwe nke okpomọkụ dị iche.

3. Meziwanye hydrophobicity nke ngwa agha ma belata mmịpụta mmiri

Ntughari polymer na-agbanwe agbanwe na-emepụta ihe nkiri n'ime oghere na elu nke ngwa agha ahụ, ihe nkiri polymer agaghị agbasa ọzọ mgbe ekpughere ya na mmiri, nke na-egbochi ntinye nke mmiri na-eme ka ọ dịkwuo mma. Pụrụ ichentụ ntụ latex redisperablena hydrophobic mmetụta nwere mma hydrophobic mmetụta.

4. Melite ike na-ehulata 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. Ya mere, ngwa ngwa ciment na-agbaji agbaji na nke siri ike na-aghọ ihe na-agbanwe. Ngwa ngwa nke nwere agbakwunyere ego nke ntụ ntụ polymer redispersible dị elu ọtụtụ ugboro karịa ngwa agha nkịtị n'ihe gbasara nkwụsi ike na ịgbagọ.

Longou compay, dị ka onye na-edugaỤlọ ọrụ RDPna China, na-elekwasị anya mgbe niile n'inye protucts dị elu na ngwọta teknụzụ nangwa agha drymix. Nabata ịkpọtụrụ anyị maka nkọwa ihe ndị ọzọ.
