Ndi zowonjezera ziti zomwe zimagwiritsidwa ntchito mu matope osakaniza ndi dry-mix?

Mtondo wosakaniza ndi madzi nthawi zambiri umakhala ndi zowonjezera zosiyanasiyana kuti ugwire bwino ntchito, ukhale wolimba, wolimba, komanso ugwirizane ndi zofunikira zosiyanasiyana zogwiritsidwa ntchito. Zowonjezera izi zimagwira ntchito yofunika kwambiri mumtondo, osati kungowonjezera magwiridwe antchito ake onse komanso kukulitsa ntchito yake m'mapulojekiti omanga. Zotsatirazi ndi kufotokozera mwachidule zowonjezera zomwe zimagwiritsidwa ntchito mumtondo wosakaniza ndi madzi ndi ntchito zake.

1. Ma ether a cellulose (monga HPMC ndi MHEC)

Hydroxypropyl methylcellulose (HPMC)ndimethyl hydroxyethyl cellulose (MHEC)Ndi zinthu zogwiritsidwa ntchito kwambiri zosungira madzi, zomwe zimapangitsa kuti madzi azigwira bwino ntchito, komanso zimathandiza kuti madzi azigwira ntchito bwino. Zingathe kuchepetsa kutaya madzi, kuwonjezera nthawi yotsegulira matope, komanso kukonza mafuta kuti agwiritsidwe ntchito bwino. Ma cellulose ethers amathandizanso kuti matope asagwedezeke komanso asamasweke, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito monga zomatira za matailosi, matope a pulasitala, ndi matope odziyimira pawokha.

2. Ufa wa Polima Wotha Kumwazikanso (RDP)

RDPNdi ufa wowonjezera womwe umabalalika kuti upange filimu ya polima. Ntchito yake yayikulu ndikuwonjezera kulimba, kusinthasintha, kukana ming'alu, komanso kukana madzi kwa matope. Amasungunukanso kukhala emulsion m'madzi, ndikupanga kapangidwe ka organic-inorganic ndi simenti, zomwe zimapangitsa kuti matopewo asagwere nyengo komanso mphamvu ya makina. RDP imagwiritsidwa ntchito kwambiri mu zomatira za matailosi, matope osalowa madzi, ndi matope omatira akunja oteteza khoma.

3. Polycarboxylate Superplasticizer

Ma polycarboxylate superplasticizers ndi othandiza kwambiri pochepetsa madzi omwe amagwiritsidwa ntchito kwambiri m'ma mortars amakono osakanikirana ndi madzi, makamaka m'ma mortars odzipangira okha komanso m'ma mortars opaka pulasitala ambiri. Ubwino wawo ndi monga kusintha kwambiri kayendedwe ka mortars, kuchepetsa kugwiritsa ntchito madzi, komanso kuwonjezera mphamvu ndi kulimba. Poyerekeza ndi ma superplasticizers achikhalidwe ochokera ku naphthalene, ma polycarboxylate superplasticizers ndi abwino kwambiri pa chilengedwe ndipo ndi oyenera kugwiritsidwa ntchito popanga zipangizo zobiriwira.

4. Zotsukira Mafoam ndi Zothandizira Kupumira Mpweya

Zipangizo zoyeretsera mpweya zimachotsa thovu lopangidwa panthawi yosakaniza matope, kupewa mavuto monga kusweka ndi kusweka, komanso kukonza bwino pamwamba. Zipangizo zopumira mpweya, kumbali ina, zimakhala ndi zotsatira zosiyana: zimayambitsa thovu laling'ono, lofanana kuti liwongolere kusunga madzi mumatope, kukana chisanu, komanso kugwira ntchito mosavuta. Zingagwiritsidwe ntchito padera kapena kuphatikiza, kutengera zomwe mankhwala akufuna.

5. Zokhuthala ndi Zosungira Madzi (Zosakhala Cellulose)

Kuwonjezera pa ma ether a cellulose, ma polima ena achilengedwe kapena opangidwa, monga ma ether a starch, guar gum, ndi polyvinyl alcohol, amagwiritsidwanso ntchito kwambiri. Zowonjezera izi zingathandize kukonza kukhuthala kwa matope ndi kusunga madzi ndipo nthawi zambiri zimaphatikizidwa ndi HPMC kuti zikwaniritse zotsatira zabwino kwambiri zogwiritsidwa ntchito.

6. Chotsitsa Choletsa ndi Chowumitsa

Zipangizo zochepetsera ntchito zimathandiza kuti matope agwire ntchito bwino komanso kupewa kuuma msanga nyengo yotentha. Nthawi zambiri zimagwiritsidwa ntchito pa ntchito zomanga zazikulu. Zipangizo zolimbikitsira ntchito zolimba zimathandiza kuti matope agwire ntchito bwino kutentha kochepa kapena pakakhala mavuto, zomwe zimapangitsa kuti ntchitoyo ikhale yolimba msanga komanso kuti ntchitoyo ipitirire mofulumira.

7. Choletsa kuzizira

Choletsa kuzizira chimagwiritsidwa ntchito makamaka m'malo omanga m'nyengo yozizira kuti matope asazizire komanso asagwe kutentha pang'ono, zomwe zimapangitsa kuti madzi azikhala bwino komanso kuti azigwirana bwino.

8. Zoletsa Madzi ndi Zoletsa Kuthira Madzi

Amagwiritsidwa ntchito polimbitsa kukana madzi kwa matope ndikuchepetsa kutembenuka kwa alkali ndi nkhungu zomwe zimachitika chifukwa cha kulowa kwa madzi. Amagwiritsidwa ntchito kwambiri mu matope akunja kwa khoma, matope osalowa madzi, komanso m'malo onyowa monga m'bafa ndi m'khitchini.

9. Zowonjezera Zina Zogwira Ntchito

Izi zikuphatikizapo ulusi woletsa kusweka (monga ulusi wa polypropylene), zolimbitsa ma bond, zodzaza (monga ma aggregates opepuka), zoletsa kutsetsereka, ndi zosinthira utoto. Zowonjezera izi zitha kusankhidwa mosinthasintha ndikugawidwa malinga ndi momwe zimagwiritsidwira ntchito pa matope (monga matope okonzera, matope okongoletsera, ndi matope oteteza kutentha).

Kugwira ntchito kwa matope osakaniza ndi dry-mixZimadalira kwambiri kuphatikiza ndi kuchuluka kwa zowonjezera zomwe zasankhidwa. Mitundu yosiyanasiyana ya matope, monga zomatira za matailosi, matope odziyimira pawokha, matope akunja a khoma, ndi matope osalowa madzi, zimafuna zowonjezera zosiyanasiyana. Kusankha bwino ndi kukonza mitundu yowonjezera ndi mlingo wake ndikofunikira kwambiri kuti zitsimikizire kuti matope osakaniza ndi owuma amagwira ntchito bwino komanso kuti agwire bwino ntchito.
