Umphumela We-RDP DOSAGE kumandla okubopha ama-putty kanye nokumelana kwamanzi

I-Putty impahla eyisisekelo esetshenziswa kabanzi kumaphrofashini okuhlobisa, futhi ikhwalithi yayo ithinta ngqo impilo yensiza kanye nomphumela wokuhlobisa we-Wall Coating. Amandla okubopha nokumelana kwamanzi kuyizinkomba ezibalulekile zokuhlola ukusebenza kwama-putty.I-redisperible latex powder, njengezinto ezisetshenziswayo ze-polymer eziguquliwe, zidlala indima ebalulekile ekwenzeni ngcono ukusebenza kwama-putty.

I-FATTEX evuselelayo ye-latex yi-powder eyakhiwa ngomishini wokufafaza we-polymer emulsion. Kungaphinde kwaphazamisa ukwakha uhlelo oluzinzile lwe-polymer lokuhlakazeka ngemuva kokuxhumana namanzi, okudlala indima ekwandiseni amandla okuqinisa nokuguquguquka kwe-putty. Imisebenzi yayo eyinhloko ifaka phakathi:

Ukwenza ngcono izibopho amandla: I-latex powder evuselelayo yakha ifilimu ye-polymer ngesikhathi senqubo yomiswa ye-putty, kanye ne-synergize ngezinto zokugcina ama-inorganic ukuthuthukisa amandla okubopha ubuhlobo.

Ukuthuthukisa ukumelana kwamanzi

Ukuthuthukisa Ukuvumelana nezimo: Kunganciphisa ubucwebe be-putty, ngcono ikhono lokukhubazeka, futhi kunciphise ubungozi bokuqhekeka.

2. Isifundo Sokuhlola

Izinto zokuhlola

I-Base Material: Ukhande osuselwa ku-Pumpy-based puttert

I-redisperible latex powder: I-Ethylene-Vinyl Acetate (EVA) Copolymer Latex Powder

Ezinye izengezo: mkhulu, i-ejenti yokugcina amanzi, i-filler, njll.

Indlela yokuhlola

Ama-PuTTies anemithambo ye-latex ehlukile ye-latex ye-latex ye-latex (0%, 2%, 5%, 8%, 10%) alungiswe ngokulandelana, futhi amandla abo okumelana namanzi ahlolwe. Amandla eBonding anqunywa isivivinyo sokukhipha, futhi ukuhlolwa kokumelana kwamanzi kwahlaziywa ngamanani okugcinwa kwamandla ngemuva kokucwiliswa emanzini amahora angama-24.

3. Imiphumela Nengxoxo

Umphumela we-latex evuselelayo ye-latex emandleni okubopha

Imiphumela yokuhlola ikhombisa ukuthi ngokwanda kwemithamo ye-RDP, amandla eBonding of putty akhombisa ukuthambekela kokuqala nokuzinza.

Lapho umthamo we-RDP ukhuphuka kusuka ku-0% kuye ku-5%, amandla okubopha athuthukiswa kakhulu, ngoba ifilimu ye-polymer eyakhiwe yi-RDP ithuthukisa amandla okubopha kanye nesipuni.

Qhubeka nokwandisa i-RDP ibe ngaphezulu kwama-8%, ukukhula kwamandla okubopha kuvame ukuba isicaba, futhi kungancipha kancane ku-10%, okungenzeka ukuthi kungenxa yokuthi i-RDP yeqile izothinta amandla aqinile.

Umphumela we-latex evuselelayo ye-latex yokumelana kwamanzi

Imiphumela yokuphikiswa kokumelana kwamanzi ikhombisa ukuthi inani le-RDP linomphumela omkhulu ekumelaneni kwamanzi kwe-putty.

Amandla eBonding of Putty ngaphandle kwe-RDP yehle kakhulu ngemuva kokufaka emanzini, ekhombisa ukumelana kwamanzi ampofu.

Ukungezwa kwenani elifanele le-RDP (5% -8%) kwenza ukuthi i-Putty ihlele isakhiwo esiminyene se-organic-inorganic, ithuthukisa ukumelana kwamanzi, futhi ithuthukisa kakhulu isilinganiso sokugcinwa kwamandla ngemuva kwamahora angama-24 wokucwilisa.

Kodwa-ke, lapho okuqukethwe kwe-RDP kudlula ama-8%, ukuthuthukiswa kokumelana kwamanzi kuyancipha, okungenzeka ukuthi kungaba yingoba izingxenye eziningi ze-organic zinciphisa ikhono le-anti-hydrolysis le-putty.

Iziphetho ezilandelayo zingadonswa ocwaningweni lokuhlola:

Inani elifanelekileI-redisperible latex powder(5% -8%) ingathuthukisa kakhulu amandla e-bonding kanye nokumelana kwamanzi kwe-putty.

Ukusetshenziswa ngokweqile kwe-RDP (> 8%) kungathinta ukwakheka okuqinile kwe-putty, okuholele ekunciphiseni noma kuncipheni nasekunciphiseni ukuthuthuka kwamandla okubopha kanye nokumelana kwamanzi.

Umthamo ofanele udinga ukulungisikala ngokwesimo esithile sohlelo lokusebenza se-putty ukufezekisa ibhalansi engcono kakhulu phakathi kokusebenza nezindleko.
