I-HPMC yodaka lwe-EIFS

I-HPMC imele i-hydroxypropyl methylcellulose kwaye sisongezo esiqhelekileyo kwizinto zokwakha, kubandakanywa udaka lwangaphandle lwe-Insulation kunye ne-Finishing System (EIFS). I-EIFS yinkqubo yokugquma ebonelela nge-insulation kunye nokugqitywa kokuhlobisa kwiindonga zangaphandle zezakhiwo.

Ukongeza i-HPMC kwimixube yodaka ye-EIFS yongeza iipropati ezahlukeneyo kwaye iphucula ukusebenza kwazo. Ezinye zezibonelelo eziphambili zokusebenzisa i-HPMC kwiidaka ze-EIFS ziquka:

Ukugcinwa kwamanzi: I-HPMC isebenza njenge-arhente yokugcina amanzi, ivumela udaka ukuba lugcine umthamo wamanzi ofanelekileyo ixesha elide. Oku kunceda i-samente ukuba ifake amanzi ngcono kwaye iqinisekise ukunyangwa okufanelekileyo, okuyimfuneko kuphuhliso lwamandla odaka.

Ukusebenza: I-HPMC ikwandisa ukusebenza kunye nokuhambelana kwee-mortars ze-EIFS, okwenza kube lula ukuxuba, ukusebenzisa kunye nokusabalalisa. Inceda ukufezekisa ukugudiswa kunye nokuthungwa kwinqanaba.

Ukubambelela: I-HPMC iphucula ukudibanisa kwee-EIFS zodaka kwiintlobo ezahlukeneyo ze-substrates, kubandakanywa iibhodi zokugquma kunye ne-primers. Yandisa amandla ebhondi kwaye inciphisa ithuba le-delamination okanye ukuqhekeka.

I-Sag Resistance: Ukongezwa kwe-HPMC kunceda ukuthintela udaka lwe-EIFS ekubeni lugrumbe okanye ludilike kwindawo ethe nkqo. Iphucula ukuziphatha kwe-thixotropic yodaka ukwenzela ukuba uhlale kwindawo ngexesha lokwakha ngaphandle kokuguqulwa okugqithiseleyo.

Ukumelana nokuqhekeka: I-HPMC inokomeleza ukuxhathisa kokuqhekeka kodaka, iphucule ukuqina kwayo kunye nobomi. Inceda ukunciphisa i-shrinkage kunye nokulawula ukuqhekeka okwenziwe ngenxa yokomisa okanye ukunyakaza kobushushu.

Ukuguquguquka: Ngokubandakanya i-HPMC, i-EIFS i-mortars ifumana ukuguquguquka, okuyimfuneko ukulungiselela ukunyakaza kwesakhiwo kunye nokwandiswa kwe-thermal / contraction ngaphandle komonakalo omkhulu.

Kubalulekile ukuqaphela ukuba ubungakanani obuchanekileyo be-HPMC esetyenzisiweyo kunye nokuqulunqwa kodaka lwe-EIFS lunokwahluka ngokuxhomekeke kwizinto ezifana neepropati ezifunwayo, iimeko zemozulu kunye neekhowudi zokwakha zendawo. Abavelisi beenkqubo ze-EIFS bahlala bebonelela ngezikhokelo kunye neengcebiso zokubandakanya i-HPMC okanye ezinye izongezo kwiimveliso zabo zodaka.
