Ulwazi loKhuseleko lwePolymer Powder eDispersible

Umhla wokuPoswa:24,JAN,2022

I-polymer powde enokuchithwa kwakhonarisetyenziswa ngokubanzi kudonga lwangaphandle lwesakhiwo ngomgubo weputty okanye eminye imixube yesamente, ngokuqhelekileyo inesamente kunye neminye imixube ngaphakathi, kunye nomgubo welatex oxutywe nomgubo weputty ukupeyinta ngaphandle, unika abantu uhlobo lweSinento ethambileyo. imvakalelo, kwaye inokuphucula ngokupheleleyo amandla e-adsorption yodaka, ukuze ubomi benkonzo yodonga lwangaphandle lube nde.

Umsebenzi wayo ubonakaliswa okokuqala ekuphuculeni ukunamathela komdaka, kuba i-latex powder iya kungena kwi-samente kwaye iyenze igcwele umswakama, ngoko ke amandla okubambelela angcono. Amaxesha amaninzi siba nentloko ebuhlungu ngenxa yokuba isamente ayinako ukubophelela ngamaplanga kunye nefayibha kunye nezinye izinto ezikrwada, kodwa nge i-polymer powder enokuchithwa kwakhona, akuyomfuneko ukuba sizikhathaze ngayo yonke into. Sonke siyazi ukuba ukugoba ukugoba kwe-samente kubi kakhulu emva kokuqina, kwaye ukongezwa kwe-latex powder kuya kuphucula ukuqina kwayo, ukwenzela ukuba ikwazi ukumelana noxinzelelo oluphezulu lwe-deformation. Nokuba i-microstructure yekhonkrithi yesamente iya kutshintshwa yiyo. Kuya kuthintela ukufunxwa kwamanzi kwisakhiwo sangaphakathi kwaye kuthintele ukuba amanzi angangeni. Emva koko i-anti-permeability ikhono lodonga lwangaphandle lubuye luphuculwe. Akukho mfuneko yokukhathazeka malunga nokuphuma kwamanzi ngaphakathi kwindlu xa kunetha. Phezulu.

I-polymer powder enokuchithwa kwakhonayongezwa kwi-samente, ukwenzela ukuba iinqununu ezintle ze-samente kunye nothuli zidibaniswe ngokuqinileyo, ngoko ke amandla okuthwala umthwalo wodaka aphuculwe ngokwemvelo, kwaye ukuchasana kokugqoka kuba namandla. Kwiindonga zangaphandle , Ayiyi kukhupha amanzi ngokulula, i-crack eyomileyo, i-deformation ngumgangatho womgangatho ofanelekileyo. Ngaphantsi kweemeko eziqhelekileyo, iindonga zekhonkrithi ezilula zangaphandle zihlala zinexesha elifutshane lenkonzo, kwaye kulula ukuqhekeza emva kweminyaka embalwa. Ngoko ke, ipeyinti ye-latex isoloko yongezwa kwinkqubo yokwakha kwiminyaka yamuva nje ukwandisa ubomi bayo benkonzo kunye nokuqinisekisa ubomi babahlali. Ukhuseleko lomntu kunye nepropathi.

Ngoko, apho kunokwenzekai-polymer powder enokuchithwa kwakhonazisetyenziswe?I-polymer powder enokuchithwa kwakhonaingasetyenziswa kwezi ndawo zilandelayo: isamente-based, gypsum-based, bonding mortar, udaka lokutyabeka, udaka olungangenwa manzi, udaka lokuchasa ukukrazuka, udaka lokuhombisa, udaka lwesamente, udaka lokutyabeka, udaka lwe-masonry, ukulungiswa kwekhonkrithi kunye nokulungisa Udaka, ukudibanisa. udaka, udaka lomgangatho (i-self-leveling sement mortar for the bottom layer, surface layer, njl.), ikhonkrithi eyomileyo, umaleko womgangatho womhlaba, ukudibanisa i-tile, i-adhesive yokwakha, i-agent agent, i-agent edibeneyo, i-plaster yokudibanisa, i-stucco Gypsum, i-putty yodonga lwangaphakathi, I-putty yodonga lwangaphandle, udaka lwe-diatom, iingubo ezingenamanzi, iingubo ezahlukeneyo,i-polymer powder enokuchithwa kwakhonainokusetyenziswa njengeplastiki, i-tougheners, kunye

i-thickeners ye-inorganic hydraulic materials ezifana nesamente kunye negypsum, i-Binder, i-agent-forming agent, i-agent yokukhusela amanzi.

I-polymer powde enokuchithwa kwakhonarinezi mpawu zilandelayo:

1. Imveliso ye-latex ye-powder powder ehlaziywayo yi-powder-soluble redispersible powder, i-copolymer ye-ethylene kunye ne-vinyl acetate, kunye ne-polyvinyl alcohol njenge-colloid ekhuselayo.

2. I-VAE i-latex powder ehlaziywayo ineempawu zokwenza ifilimu. Isisombululo se-50% samanzi siya kwenza i-emulsion, eya kwenza ifilimu efana neplastiki emva kokufakwa kwiglasi kwiiyure ezingama-24.

3. Ifilimu eyenziweyo inokuguquguquka okuthile kunye nokuchasana kwamanzi. Inokufikelela kwimigangatho yesizwe.

4. I-latex powder ehlaziywayo inokusebenza okuphezulu: inamandla okudibanisa okuphezulu, ukusebenza okukodwa kunye nokusebenza okugqwesileyo kokungabikho kwamanzi, amandla okudibanisa okulungileyo, ukunika udaka olubalaseleyo lokumelana ne-alkali, kwaye inokuphucula ukubambelela kunye namandla okuguquguquka kodaka , Ukongeza kwiplastiki. , ukuxhathisa ukunxiba kunye nokusebenza, kunokuguquguquka okunamandla kwi-anti-cracking mortar.
