Mpahla ukuze isisombululo eziphathekayo: yintoni na kwaye kutheni na ufuna ukuba

Kwezithako leyo ngcono iimpawu ngodaka eziphathekayo ezifunyenwe ngeendlela acid, ebizwa plasticizers. Kwaye zingadityaniswa nje kuphela isisombululo sewulungile, kodwa kwinqanaba ukugaya lwesamente.

Akukho mfuneko ukucinga ukuba plasticizer ukuba isisombululo isamente ikhona kuphela yinguqulelo enye. Inyaniso kukuba ehlabathini kukho imali enkulu kwiintlobo eziphathekayo, ngamnye ekufuneka kuphuculwe kunye nokulungiswa kwezakhiwo ezithile. Noko ke, ukuba ezinye iimpawu eziqhelekileyo, ezibandakanya uluhlu standard kuphucula ukusebenza. Makhe uthi kubo:

• plasticizer esihle mortars Iya ziyakwehlisa ngokubonakalayo ukusetyenziswa kwezinto ukwakha;
• iimpawu kwakuse le concrete ziphucukile, kwaye umlinganiselo zesamente kunye namanzi, nangona kunjalo, uhlala efanayo;
• Le umxube wamanzi ngumkhenkce kubushushu obuphantsi, kwaye inqaba "nobusika" kwandisa eziphathekayo, ngaphezulu, kunciphise kakhulu iindleko ngokushushubeza isisombululo okanye ukusetyenziswa kwezinye wezenzi kwemichiza;
• ukumelana amanzi kunye impermeability igesi kweemveliso ezigqityiweyo is ngcono kakhulu.

ngezigaba kwezithako

Ukuze siqonde ngcono iimpawu zabo, kufuneka ubuncinane kalukhuni ukwazi kucalulo ngokwanelisayo elula awuthatha njengofanalekileyo ukuba ukhethe plasticizer nesisombululo. Okokuqala, makhe sithethe ngokwahlukana kwabo, ngokuxhomekeke umgaqo yokusebenza:

• ehlanganisa okanye inhibitors lukhuni zekhonkrithi;
• modifiers adlulisela iimpawu ezikhethekileyo eziphathekayo ogqityiweyo (ukuxhathisa kukhukuliseko, amaqondo obushushu aphezulu, ityuwa, njalo njalo. d.).

Ukuba sithethe ngamandla isenzo, lo plasticizer ngenxa wamatye ludaka ukuze nomelele, eliphakathi okanye ababuthathaka. Ngaba mono-, in- kunye polyvalent umxube izongezo zokwenziwa ngokupheleleyo nezimbiwa.

Umgangatho kunye nokusebenza plasticizers

Xa iinkcukacha wemveliso ogqityiweyo uchatshazelwa kuphela uhlobo kunye neempawu plasticizer, kodwa umgangatho ngesamente ngokwayo, apho kusetyenziswa isisombululo nomkhombe. athandwa kakhulu phakathi abakhi zobungcali unandipha eziveliswa nkampani Rhein-Chemotechnik GmbH (Germany).

Le Isisombululo plasticizer German kubalungele yokusebenza kwalo. Ngokuyintloko ekuveliseni izisombululo naluphi na udidi, kuya kufuneka isixa ubuncinane isilungisi. Ukongeza, usebenzisa indibaniso ezahlukeneyo kuphela iindidi eziliqela kwezithako, kunokwenzeka ukuba ukhethe ulandelelwano kuxhanyulwa phantse onke amabakala ngekonkriti. Lula ukusetyenziswa kwakhona ngenxa yobukho ophezulu ezikumgangatho kunye imiyalelo eneenkcukacha.

UPawulos, singatsho ukuba plasticizer ukuba isisombululo (ixabiso elandelwayo exhomekeke umenzi) akakwazi kakhulu nje ekunciphiseni iindleko zezixhobo zokwakha, kodwa kwandisa ngokubonakalayo imveliso yabasebenzi. Ukongeza, ubukho iintlobo ezahlukeneyo eyiyo yebug kwaye ungakwazi lula ukubeka up ukuveliswa elula kuphela udaka, kodwa elungileyo amagwebu esemgangathweni. Ngenxa iindleko zokwakha kwiminyaka yakutshanje, kubalulekile ngokukodwa hayi kuphela iinkampani kodwa abantu.
