Madandaulo a Makasitomala: Simenti siyingawume Mukawonjezera MHEC kapena HPMC yanu. — 11 Oct. 2023
Padziko lonse la zomangamanga ndi zomangamanga, simenti ndi yofunika kwambiri. Zimagwira ntchito ngati chomangira, kupereka mphamvu ndi kukhazikika kwa zomangamanga. Komabe, posachedwapa, pakhala pali madandaulo ambiri amakasitomala okhudzana ndi kusayanika kwa simenti moyenera atagwiritsa ntchito MHEC (Methyl Hydroxyethyl Cellulose), chowonjezera chomwe chimagwiritsidwa ntchito popanga simenti.
MHEC imagwiritsidwa ntchito kwambiri pantchito yomanga kuti ikweze zida za simenti. Imagwira ntchito ngati chosungira madzi, kukonza magwiridwe antchito komanso kuchepetsa kufunikira kwa madzi. Chowonjezera ichi chimadziwika chifukwa cha kuthekera kwake kuonjezera zomatira za simenti, zomwe zimapangitsa kuti zikhale zofunikira kwambiri popanga zipangizo zosiyanasiyana zomangira.
Komabe, makasitomala ena anena kuti simentiyo, ngakhale itakhala nthawi yayitali, imalephera kuuma mokwanira. Nkhaniyi yadzetsa nkhawa osati pakati pa ogwiritsa ntchito payekha komanso pakati pa makampani omanga, zomwe zimapangitsa kuchedwa ndi ndalama zowonjezera. Zimakhala zofunikira kusanthula zomwe zimayambitsa madandaulo amakasitomalawa ndikupeza njira zothetsera mavutowo.
Chifukwa chimodzi chomveka chopangitsa kuti simenti isaumitsidwe kungakhale mlingo wosayenera wa MHEC. Chiwerengero chenicheni cha chowonjezera ichi chiyenera kuwerengedwa mosamala kuti zitsimikizidwe zomwe zimafunidwa za kusakaniza kwa simenti. Ngati mlingo umaposa malire ovomerezeka, ukhoza kukhudza njira ya hydration ndikulepheretsa kuyanika kwa simenti. Chifukwa chake, ndikofunikira kuti opanga ndi makontrakitala azitsatira malangizowo ndikugwiritsa ntchito mulingo woyenera wa MHEC.
Kuphatikiza apo, mtundu wa MHEC womwe umagwiritsidwa ntchito popanga simenti umathandizira kwambiri pakuwumitsa. Zowonjezera zotsika kapena zodetsedwa zitha kukhala ndi zowononga zomwe zimasokoneza machitidwe amankhwala ofunikira kuti simenti ichire bwino. Opanga ayenera kuika patsogolo kupeza MHEC kuchokera kwa ogulitsa odalirika ndi odziwika bwino kuti athetse vutoli.
Mfundo ina yofunika kuiganizira ndi mmene chilengedwe chimakhalira poika simenti ndi pambuyo pake. Kuyanika kwa simenti kumadalira kwambiri kutentha ndi chinyezi. Kutentha kwambiri kapena kutsika kwambiri, komanso chinyezi chambiri, kungalepheretse kuyanika kwa simenti, mosasamala kanthu za kukhalapo kwa MHEC. Makasitomala akuyenera kudziwitsidwa za momwe chilengedwe chilili bwino kuti simenti iume bwino.
Kuphatikiza apo, kusakanikirana kosakwanira kwa MHEC ndi kusakaniza kwa simenti kungayambitsenso kuyanika kokwanira. Chowonjezeracho chiyenera kumwaziridwa mofanana mu simenti yonse kuti zitsimikizidwe kuti zikugwira ntchito mofanana. Opanga akuyenera kulingalira za kuyika ndalama pazida zosakaniza bwino kuti akwaniritse kuphatikiza kofanana.
Pofuna kuthana ndi madandaulo a makasitomala okhudzana ndi simenti yosawuma mokwanira, ndikofunikira kuti opanga azichita kafukufuku ndi kusanthula bwino. Ayenera kugwirizana ndi akatswiri ndi akatswiri pantchitoyo kuti adziwe zomwe zimayambitsa vutoli ndikuwongolera zofunikira. Kuphatikiza apo, opanga amafunika kupititsa patsogolo kulumikizana ndi makasitomala ndikupereka malangizo omveka bwino ndi malangizo kuti awonetsetse kuti MHEC ikugwiritsidwa ntchito moyenera.
Pomaliza, madandaulo amakasitomala aposachedwa okhudzana ndi simenti yosawuma atagwiritsa ntchito MHEC akuwonetsa kufunikira kwa opanga ndi makampani omanga kuti awunikenso momwe amapangira. Mlingo woyenera, zowonjezera zapamwamba, malo abwino a chilengedwe, ndi kusakaniza yunifolomu ndizofunikira kwambiri zomwe ziyenera kuganiziridwa kuti zithetse vutoli. Pothana ndi zovuta izi, opanga amatha kukulitsa kukhutitsidwa kwamakasitomala, kuwongolera njira zomangira, ndikuwonetsetsa kuti simenti ikuchiritsidwa bwino ndi kuyanika.
Zikomo chifukwa cha thandizo lanu JINJI CHEMICAL!
