Mgbe ntụ latex gbazere na mmiri, ọ na-emepụta ihe colloidal, nke nwere ike ịmepụta ike anụ ahụ na kemịkalụ siri ike n'etiti putty na elu ala ahụ. Nrapado emelitere nwere ike ime ka mmetụta owuwu nke putty dịkwuo mma nke ukwuu, zere mgbawa, ịwụfu na nsogbu ndị ọzọ, ma gbasaa ndụ ọrụ nke putty.
2. Meziwanye mgbanwe na iguzogide mgbawa nke putty
Mgbanwe nke putty bụ isi ihe na-emetụta ike ya na arụmọrụ ya. Ntụ ntụ latex na-agbanwe agbanwe na-arụ ọrụ n'ịbawanye ike na mgbanwe na putty. N'ihi mmetụta nke usoro molekul nke ntụ latex, putty nwere ike nweta ụfọdụ ike mgbanwe mgbe ọ kpọnwụrụ, ma nwee ike ịgbanwe na obere mgbanwe nke elu ntọala, si otú a na-ebelata mgbawa nke ihe ndị dị ka mgbanwe okpomọkụ na mgbanwe iru mmiri kpatara. Nke a dị oke mkpa maka ịma mma na ịdịgide nke mma mgbidi.
3. Meziwanye iguzogide mmiri na iguzogide ihu igwe nke putty
Ntụ latex nwere ike ime ka putty ghara iguzogide mmiri nke ọma site n'ime ka putty ghara inwe mmetụta mmiri. Putty ọdịnala na-amịkọrọ mmiri ngwa ngwa ma na-aza n'ebe mmiri dị, na-eme ka oyi akwa putty ahụ gbapụ ma buo. Mgbe etinyere ntụ latex a na-agbagharị agbagharị, ikike ịmịkọrọ mmiri nke putty na-ebelata nke ukwuu, ọ nwekwara ike iguzogide oke mbuze mmiri ụfọdụ. Na mgbakwunye, itinye ntụ latex na-emekwa ka iguzogide ihu igwe nke putty ka mma, ka putty wee nwee ike ịnọgide na-arụ ọrụ nke ọma mgbe o kpugheere ya ogologo oge na gburugburu ebe siri ike dịka ifufe, mmiri ozuzo na anyanwụ.
4. Meziwanye arụmọrụ owuwu nke putty
Ntụ latex nke a na-emegharị emegharị nwere ike ime ka arụmọrụ nke putty ka mma. Mgbakwunye nke ntụ latex na-eme ka putty dị mfe itinye ma rụọ ọrụ, na-ebelata ihe isi ike na ike ọrụ nke owuwu. Ntụ latex na-agbanwe agbanwe ga-aka mma, a pụkwara ime ka ịdị larịị na nrapado nke mkpuchi ahụ ka mma. Ntụ latex na-eme ka putty nwee ihe onwunwe na-agwọ ngwa ngwa n'oge usoro nkụcha, na-ezere mgbawa ma ọ bụ mkpuchi na-adịghị mma nke putty na-akpọ nkụ ngwa ngwa n'oge owuwu.
5. Meziwanye iguzogide ntu oyi nke putty
N'ebe oyi na-atụ, putty nwere ike ịla n'iyi n'ọrụ mbụ ya n'ihi obere okpomọkụ, ma ọ bụ ọbụna ibute nsogbu dịka mgbawa na ịda. Mgbakwunye nke ntụ latex redispersible nwere ike ime ka iguzogide ntu oyi nke putty ka mma nke ukwuu. Ntụ latex nwere ike ịnọgide na-enwe ezigbo nkwụsi ike n'okpuru ọnọdụ okpomọkụ dị ala ma zere nsogbu dị mma nke putty n'ihi oyi. Ya mere, iji ntụ latex nwere putty n'ebe oyi na-atụ dịka ugwu nwere ike ime ka nkwụsi ike na ntụkwasị obi nke ngwaahịa ahụ ka mma nke ukwuu.
6. Belata porosity ma mee ka njupụta nke putty dịkwuo mma
Mgbakwunye ntụ latex nwere ike ibelata porosity nke putty nke ọma ma mee ka njupụta nke putty dịkwuo mma. N'oge nhazi ihe nkiri nke putty, ntụ latex nwere ike ijupụta obere oghere dị n'ime putty, belata ntinye nke ikuku na mmiri, ma melite iguzogide mmiri, iguzogide mmetọ na iguzogide mmetụta nke putty. Mkpụkọ nke putty nwere mmetụta dị oke mkpa na ogologo oge nke mgbidi ahụ, ọ nwekwara ike ime ka mma nke mgbidi ahụ dịkwuo mma nke ọma mgbe ejiri ya ogologo oge.
7. Meziwanye ihe onwunwe mgbochi mmetọ nke putty
Akwa putty bụ akwa isi nke agba ahụ. Ikpughe ogologo oge na uzuzu, mmanụ, ihe acidic na alkaline n'ikuku na ihe ndị ọzọ na-emerụ ahụ ga-emetụta mmetụta ikpeazụ nke agba ahụ. Ntụ latex redispersible na-enyere aka belata ikike mmịpụta nke elu putty, si otú a na-ebelata nrapado nke ihe ndị na-emerụ ahụ. Nke a abụghị naanị na ọ na-eme ka putty sie ike, kamakwa ọ na-eme ka agba mgbidi mara mma.
8. Mee ka ọkpụrụkpụ ihe owuwu nke putty dịkwuo elu
Ebe ọ bụ na ntụ latex nwere ike ime ka njikọ na mmiri putty dịkwuo mma nke ọma, putty na-eji ntụ latex nwere ike ịkwado ọkpụrụkpụ ihe owuwu buru ibu. Njirimara a dị mkpa karịsịa maka ụfọdụ mgbidi ndị chọrọ ọkpụrụkpụ ka ukwuu iji rụzie, nke nwere ike ime ka mgbidi a rụziri dị nro ma ghara inwe mgbawa n'oge ojiji ogologo oge.
Mmetụta nkentụ ntụ latex a na-emegharị emegharịna putty nwere ọtụtụ akụkụ, nke a na-egosipụtakarị na ime ka njikọ dị mma, mgbanwe, iguzogide mmiri, iguzogide ntu oyi, arụmọrụ owuwu na mgbochi mmetọ nke putty. Dịka ezigbo ihe na-agbanwe agbanwe, ntụ latex nwere ike ọ bụghị naanị ime ka mma nke putty dịkwuo mma ma mee ka ọ sie ike, kamakwa ọ na-eme ka putty dịkwuo mma n'ebe owuwu dị iche iche. Ka ihe ụlọ ọrụ owuwu chọrọ maka ịdị mma owuwu mgbidi na-abawanye, itinye ntụ latex a na-agbanwe agbanwe ga-abawanye ụba, mmetụta ya na ngwaahịa putty ga-adịkwa mkpa karị.
