Imisebenzi ye-polymer powder ehlakazeka kabusha

I-polymer powder ehlakazeka kabushai-polymer emhlophe egeleza mahhala engakwazi ukuphinda i-emulsified futhi ihlakazwe emanzini ukuze yakhe i-emulsion ezinzile. Ingaxutshwa nezinye izinto eziyimpuphu ezifana usimende, isihlabathi, i-aggregate engasindi, njll. efektri yokukhiqiza ngokwesilinganiso esithile esimweni esomile ukuze kutholwe isimende esixutshwe nesomile esiseqophelweni eliphezulu futhi okulula ukusisebenzisa, okunganciphisa ukwakhiwa kwendawo. Iphutha kanye nokuphazamiseka lapho uxuba futhi ukala nge-emulsion.

Imisebenzi eyisithupha ye-polymer powder ehlakazeka kabusha:

1. Thuthukisa amandla okunamathela nokubumbana

Emikhiqizweni yodaka olomile lukasimende, kudingekile kakhulu ukwengeza impushana ye-polymer ehlakazekayo. Kusobala kakhulu ukuthuthukisa amandla okubopha nokuhlangana kwezinto. Lokhu kungenxa yokungena kwezinhlayiya ze-polymer kuma-pores kanye nama-capillaries we-matrix ye-cement, kanye nokwakhiwa kwamandla okuhle okuhlangene ne-samente ngemva kwe-hydration. Ngenxa yokunamathela okuhle kakhulu kwe-polymer resin ngokwayo, ingathuthukisa ukunamathela kwemikhiqizo yodaka lukasimende kuma-substrates, ikakhulukazi izibophezelo ze-inorganic ezifana usimende ziboshelwe kuma-substrates e-organic njengokhuni, i-fiber, i-PVC ne-EPS. Ukwenziwa ngcono kokusebenza kabi kunomphumela osobala kakhulu.

2. Thuthukisa ukugoba nokumelana nokuqina

Kuhlaka lwamathambo oluqinile olwakhiwe ukugeleza kodaka lukasimende, ifilimu ye-polymer iyanwebeka futhi iqinile. Phakathi kwezinhlayiya zodaka lukasimende, lisebenza njengesihlanganisi esinyakazayo, esingamelana nemithwalo ye-deformation ephezulu futhi sinciphise ukucindezeleka, okwenza ukuphikiswa kwe-Tensile nokugoba kuthuthukiswe.

3. Thuthukisa ukumelana nomthelela

I-polymer powder ehlakazeka kabusha, inhlaka ye-thermoplastic. Ifilimu ethambile eboshwe ebusweni bezinhlayiya zodaka, engakwazi ukudonsa umthelela wamandla angaphandle futhi iphumule ngaphandle kokuphuka, ngaleyo ndlela ithuthukise ukumelana komthelela wodaka.

4, thuthukisa i-hydrophobicity futhi unciphise izinga lokumuncwa kwamanzi

Ukwengeza i-polymer powder ehlakazekayo kungathuthukisa i-microstructure yodaka lukasimende. I-polymer yayo yakha inethiwekhi engenakuhlehliswa enqubweni ye-cement hydration, ivala i-capillary kujeli ye-cement, ivimbele ukumuncwa kwamanzi, ivimbele ukungena kwamanzi, ngaleyo ndlela ithuthukise ukungakwazi ukungena.

5. Thuthukisa ukumelana nokugqoka nokuqina

Ukwengezwa kwempushana ye-polymer ehlakazekayo kungakhuphula isibopho esiminyene phakathi kwezinhlayiya zodaka lukasimende nefilimu ye-polymer. Ukuthuthukiswa kwamandla ahlangene ngokuhambisanayo kuthuthukisa ikhono lodaka lokumelana nokucindezeleka kwe-shear, ukuze izinga lokugqoka linciphe, ukumelana nokugqoka kuthuthukiswe, futhi impilo yesevisi yodaka inwetshiwe.

6. Thuthukisa ukuzinza kweqhwa futhi uvimbele ngempumelelo ukuqhekeka kwezinto

Impushana ye-polymer ehlakazeka kabusha, ipulasitiki yeresin yayo ye-thermoplastic, inganqoba umonakalo wokunwebeka okushisayo nokufinyela okubangelwa ukushintsha kwezinga lokushisa ezintweni zodaka lukasimende. Ukunqoba ukushiyeka kodaka olulula lukasimende nge-deformation enkulu yokomisa i-shrinkage kanye nokuqhekeka okulula, kungenza izinto eziguquguqukayo, ngaleyo ndlela kuthuthukiswe ukuzinza kwesikhathi eside kwezinto.
