ntụ ntụ latex na-agbanwe agbanwe (RDP)bụ ihe a na-eji polymer eme ihe n'ọtụtụ ebe na ụlọ ọrụ ihe owuwu, nke a na-ejikarị dị ka ihe mgbakwunye maka putty, mkpuchi, nrapado na ngwaahịa ndị ọzọ. Isi ọrụ ya bụ imeziwanye mgbanwe, adhesion, mgbochi mmiri na mgbochi ịka nká nke ngwaahịa ahụ.
1. Meziwanye adhesion nke putty
Mgbakwunye nke latex ntụ ntụ redispersible na putty nwere ike ime ka njikọ dị n'etiti putty na elu ala (dị ka simenti, bọọdụ gypsum, wdg). Mgbe uzuzu latex gbazere n'ime mmiri, ọ na-etolite ihe colloidal, nke nwere ike ime ka njikọ anụ ahụ na kemịkal dịkwuo ike n'etiti putty na ala ala. Nchikota nke ọma nwere ike imeziwanye mmetụta nrụpụta nke putty, zere mgbawa, ịkwatu na nsogbu ndị ọzọ, na ịgbatị ndụ ọrụ nke putty.
2. Meziwanye mgbanwe na mgbape mgbape nke putty
Mgbanwe nke putty bụ isi ihe na-emetụta ịdịte aka ya na ịrụ ọrụ ihe owuwu. Uzuzu latex na-agbanwe agbanwe na-ekere òkè n'ịbawanye ngbanwe na mgbanwe na putty. N'ihi mmetụta nke molekụla yinye nke latex ntụ ntụ, putty nwere ike nweta ụfọdụ elasticity mgbe ihicha, na nwere ike ime mgbanwe na ntakịrị nrụrụ nke isi elu, si otú ibelata cracks kpatara ihe ndị dị ka okpomọkụ mgbanwe na iru mmiri fluctuations. Nke a dị oké mkpa maka ịma mma na ịdịte aka nke ịchọ mma mgbidi.
3. Meziwanye ihe mgbochi mmiri na nguzogide ihu igwe nke putty
Uzuzu latex nwere ike imeziwanye nguzogide mmiri nke putty site na imeziwanye hydrophobicity nke putty. Putty omenala na-amịkọrọ mmiri n'ụzọ dị mfe ma zaa na gburugburu ebe iru mmiri, na-eme ka oyi akwa putty na-agbapụ ma na-akpụzi ya. Mgbe agbakwunyere redispersible latex ntụ ntụ, ikike nnabata mmiri nke putty na-ebelata nke ukwuu, ọ nwekwara ike iguzogide ụfọdụ ogo mmiri mbuze. Tụkwasị na nke ahụ, mgbakwunye nke ntụ ntụ latex na-eme ka ihu igwe na-eguzogide ọgwụ nke putty, nke mere na putty ka nwere ike ịnọgide na-arụ ọrụ dị mma mgbe ogologo oge na-ekpughere gburugburu ebe siri ike dị ka ifufe, mmiri ozuzo na anyanwụ.
4. Meziwanye ihe owuwu nke putty
Uzuzu latex na-agbanwe agbanwe nwere ike imeziwanye arụmọrụ ihe owuwu nke putty. Mgbakwunye nke latex ntụ ntụ na-eme ka putty dị mfe itinye ma rụọ ọrụ, na-ebelata ihe isi ike na ike ịrụ ọrụ nke ihe owuwu. Mmiri mmiri na ịrụ ọrụ nke putty ga-aka mma, a pụkwara imeziwanye ihe nrịbama na adhesion nke mkpuchi. Uzuzu latex na-eme ka putty nwee ụfọdụ ihe eji agwọ ọrịa ngwa ngwa n'oge usoro ihicha, na-ezere mgbawa ma ọ bụ mkpuchi na-enweghị isi nke kpatara ihicha ngwa ngwa putty n'oge a na-ewu ya.
5. Melite ntu oyi nke putty
N'ebe oyi na-atụ, putty nwere ike ịkwụsị ọrụ mbụ ya n'ihi obere okpomọkụ, na ọbụna na-akpata nsogbu dị ka mgbawa na ịdaba. Mgbakwunye nke redispersible latex ntụ ntụ nwere ike imeziwanye ntu oyi nke putty. Uzuzu latex nwere ike idowe ezigbo nkwụsi ike n'usoro n'okpuru ọnọdụ okpomọkụ dị ala ma zere nsogbu dị mma nke putty n'ihi na oyi. Ya mere, iji putty nwere latex ntụ ntụ na mpaghara oyi dị ka ugwu nwere ike ime ka nkwụsi ike na ntụkwasị obi nke ngwaahịa ahụ dịkwuo mma.
6. Belata porosity ma welie njupụta nke putty
Mgbakwunye nke latex ntụ ntụ nwere ike belata porosity nke putty nke ọma ma welie njupụta nke putty. N'oge usoro nhazi ihe nkiri nke putty, uzuzu latex nwere ike mejupụta obere pores n'ime putty, belata ntinye nke ikuku na mmiri, ma na-eme ka mmiri na-eguzogide mmiri, mmetọ mmetọ na mmetụta nkwụsị nke putty. Ngwakọta nke putty nwere mmetụta dị oke mkpa na njedebe zuru oke nke mgbidi ahụ, ọ pụkwara imeziwanye mgbidi mgbidi ahụ nke ọma mgbe ejiri ogologo oge mee ihe.
7. Meziwanye ihe mgbochi mmetọ nke putty
Ngwunye putty bụ isi oyi akwa nke agba. Ogologo ogologo oge na uzuzu, mmanụ, acidic na alkaline na ikuku na ihe ndị ọzọ na-emetọ ihe ga-emetụta mmetụta ikpeazụ nke agba. Uzuzu latex na-agbanwe agbanwe na-enyere aka ibelata ikike mgbasa ozi nke elu putty, si otú ahụ belata nrachi nke mmetọ. Nke a ọ bụghị nanị na-eme ka ịdịte aka nke putty dịkwuo mma, ma na-ejikwa mma nke agba mgbidi.
8. Dịkwuo ihe owuwu nke putty
Ebe ọ bụ na uzuzu latex nwere ike imeziwanye arụmọrụ njikọ na mmiri mmiri nke putty, putty na-eji ntụ ntụ latex nwere ike ịkwado nnukwu owuwu ihe owuwu. Njirimara a dị mkpa karịsịa maka mgbidi ụfọdụ na-achọ ka ọkpụkpụ buru ibu na-arụzi, nke nwere ike hụ na mgbidi a na-edozi na-adị nro ma na-adịchaghị mfe mgbawa n'oge eji ogologo oge.
Mmetụta nkentụ ntụ latex redisperableon putty bụ multifaceted, tumadi na-egosipụta na melite adhesion, mgbanwe, mmiri na-eguzogide, ntu oyi eguzogide, ewu arụmọrụ na mgbochi mmetọ nke putty. Dị ka ihe ngbanwe dị mma, ntụ ntụ latex nwere ike ọ bụghị naanị ịkwalite mma nke putty ma mee ka ọ dịkwuo ogologo oge, kamakwa mee ka putty dịkwuo mfe na gburugburu ebe obibi dị iche iche. Ka ihe ndị ụlọ ọrụ na-ewu ihe chọrọ maka ịdị mma mgbidi mgbidi na-abawanye, ntinye nke ntụ ntụ latex redispersible ga-abawanye ụba, mmetụta ya na ngwaahịa putty ga-adịkwa mkpa.
