I-plaster yamakhemikhali

Enye indlela yokuhlobisa kwangaphandle nokungaphakathi kwezindonga kuyisetshenziswa se-samente-umquba wokugaya. Isetshenziselwa ukubhekene nezindonga ezenziwe ngekhonkrithi ekhishiwe, ukhonkolo kanye nezitini . Akusebenzi neze lolu hlobo lwamapulangwe ngezindawo ezidwetshiwe nezokhuni, kanye nezindawo zokulinganiswa kwanoma yiluphi uhlobo.

Ukwakhiwa kwamakhemikhali ensimbi

Cabangela ukwakheka kwe-samente-lime. Izingxenye eziyinhloko zalesi sakhiwo yi-samente, i-lime nesihlabathi. Kuye ngenhloso yesicelo, isilinganiso sobukhulu bezingxenye singalungiswa. Ngaphezu kwalokho, ungathenga umkhiqizo owomile owenziwe ngomakethe futhi wanezela nje amanzi ukuze uqalise, noma ungakwenza ngokwakho. Kulesi simo, uzokwazi ukucacisa ngokucacile izilinganiso ezidingekayo. Isibonelo, ngokunciphisa kwesabelo samamente nokunyuka kwesilinganiso se-lime, lo mthombo uzolahlekelwa amandla awo, futhi kwandiswe isikhathi sokwandisa isikhathi esinzima.

Izici zobuchwepheshe be-plasi-lime plasters

Izici zezobuchwepheshe ze-plaster-lime plasters kufaka okulandelayo:

1. Isikhathi sokusetshenziswa kwesisombululo esiphelile sisukela kuhora elilodwa kuya kweyesibili. Kuxhomeke kumkhiqizi kanye nenani elilinganiselwe lezingxenye ezisendayini.
2. Amandla okunamathela noma odongeni odongeni akusilo ngaphansi kuka-0.3 MPa.
3. Amandla okuqeda amandla angaphansi kuka-5.0 MPa.
4. Ukushisa okusebenzayo -30 ° C kuya ku- 70 ° C. Ngokwale parameter yezobuchwepheshe, imingcele eyinqaba inikezwa. Lokhu akusho ukuthi lesi sikhashana sisebenziseka kuma-plaster e-lime nesimiso nanoma yisiphi isakhiwo nanoma yimaphi amandla.
5. Ukusetshenziswa kwempahla ngayinye imitha yemitha yesikwele kusuka ku-1.5 kg ukuya ku-1.8 kg ubukhulu bezingqimba ze-1 mm.
6. Isitoreji sisezikhwama. Nokho, uma uvula isikhwama, kunconywa ukuthi uyisebenzise ngokuphuthumayo. Kusukela ngaphansi kwezinto ezithinta imvelo, izinto zingafika esimweni esingafanele ukusetshenziswa okuqhubekayo (isibonelo, kanzima kusuka umswakama).

Kunconywa ukuba usebenze ngodaka lwamakhemikhali amakhemikhali ama-plaster emazingeni okushisa angama-5 ° C kuya ku-30 ​​° C. Futhi ngokuqondene nomswakama womoya akungaphansi kuka-60%. Kuhle ukuthi ngesikhathi sokumisa nokuqina kwengubo kuyokwazi ukugcina umswakama ebangeni kusukela ku-60% ukuya ku-80%. Endabeni yokufaka ngaphakathi ngaphakathi ekamelweni, kuzodingeka ukuba umoya ophuthumayo kabili ngosuku, lokhu kuzokusiza ukuqina kanzima komhlabathi wensimu.
