Wamba mkati khoma putty phala

1. Mitundu ndi kusankha kwa zopangira za phala wamba wa putty

(1) Heavy calcium carbonate

(2) Hydroxypropyl Methyl Cellulose Etha (Mtengo wa HPMC)

HPMC ili ndi kukhuthala kwakukulu (20,000-200,000), kusungunuka kwamadzi bwino, kulibe zonyansa, komanso kukhazikika bwino kuposa sodium carboxymethylcellulose (CMC). Chifukwa cha zinthu monga kutsika kwamitengo ya zinthu zopangira kumtunda, kuchulukirachulukira, komanso kukulitsa mpikisano wamsika, mtengo wamsika wa HPMC Popeza umawonjezedwa pang'ono komanso mtengo wake siwosiyana kwambiri ndi wa CMC, HPMC itha kugwiritsidwa ntchito m'malo mwa CMC. kupititsa patsogolo ubwino ndi kukhazikika kwa putty wamba.

(3) Ufa wa polima wamtundu wa zomera

dispersible polima ufa ndi wapamwamba kwambiri wopangidwa ndi polima polima ufa, womwe uli ndi makhalidwe oteteza chilengedwe ndi thanzi, kukhazikika kwabwino, kutsutsa kukalamba, ndi mphamvu zomangirira kwambiri. Mphamvu yolumikizirana yamadzimadzi ndi 1.1Mpa pamlingo wa 10%. .

Kukhazikika kwa RDP ndikwabwino. Kuyesa ndi yankho lamadzimadzi ndi mayeso osindikizidwa osungiramo amadzimadzi amadziwonetsa kuti yankho lamadzimadzi limatha kukhalabe lokhazikika la masiku 180 mpaka masiku 360, ndipo ufa ukhoza kukhalabe wokhazikika wazaka 1-3. Chifukwa chake, RDP -2 Ubwino ndi kukhazikika ndizabwino kwambiri pakati pa ufa wapolima wapolima. Ndi colloid yoyera, 100% yosungunuka m'madzi, komanso yopanda zinyalala. Itha kugwiritsidwa ntchito ngati zopangira zapamwamba za ufa wamba wa putty.

(4) Dothi la diatomu loyambirira

Matope amtundu wa mapiri a diatom atha kugwiritsidwa ntchito popanga ufa wofiyira, wopepuka wachikasu, woyera, kapena wobiriwira wobiriwira wa matope a diatom okha, ndipo amatha kupangidwa kukhala phala loyera loyeretsa mpweya.

(5) Fungicide

2. Kupanga chilinganizo cha wamba apamwamba mkati khoma putty phala

Zopangira dzina Reference mlingo (kg)

Normal kutentha madzi oyera 280-310

Chithunzi cha RDP7

Hydroxypropyl methylcellulose (HPMC, 100000S) 3.5

Kashiamu wolemera ufa (200-300 mauna) 420-620

pulayimale diatom matope 100-300

Madzi opangidwa ndi fungicide 1.5-2

Zindikirani: Malingana ndi ntchito ndi mtengo wa mankhwala, onjezani dongo loyenera, ufa wa chipolopolo, ufa wa zeolite, tourmaline ufa, ufa wa barite, ndi zina zotero.

3. Zida zopangira ndi zamakono

(1) Choyamba kusakaniza RDP, HPMC, heavy calcium powder, primary diatom matope, etc. ndi chosakaniza chowuma cha ufa ndikuyika pambali.

(2) Panthawi yopangira, choyamba onjezerani madzi ku chosakanizira, kenaka yikani fungicide yochokera kumadzi, yatsani chosakanizira chapadera cha putty phala, pang'onopang'ono ikani ufa wosakanizidwa kale mu chosakanizira, ndikuyambitsanso ndikuwonjezera mpaka ufa Zonse zitabalalika. kukhala yunifolomu phala state.

4. Zofunikira zamakono ndi luso la zomangamanga

(1) Zofunikira zapansi panthaka

Pamaso kumanga, wosanjikiza m'munsi ayenera mosamalitsa ankachitira kuchotsa phulusa akuyandama, madontho mafuta, looseness, pulverization, bulging, ndi dzenje, ndi kudzaza ndi kukonza mabowo ndi ming'alu.

Ngati khomalo silikuyenda bwino, matope apadera oletsa ming'alu a m'kati mwake angagwiritsidwe ntchito kuwongolera khomalo.

(2) Ukadaulo wa zomangamanga

Kupaka pulasitala pamanja: malinga ngati maziko ake ndi khoma la simenti lomwe lili lathyathyathya, lopanda ufa, madontho amafuta, ndi fumbi loyandama, limatha kupukutidwa kapena kupindika.

Kupaka pulasitala: Kukhuthala kwa pulasitala iliyonse ndi pafupifupi 1mm, yomwe iyenera kukhala yopyapyala osati yokhuthala.

Chovala choyamba chikawuma mpaka sichimamatira, ndiye gwiritsani ntchito malaya achiwiri. Nthawi zambiri, malaya achiwiri amakhalabe ndi moyo.

5. Nkhani zofunika kuziganizira

(1) Ndizoletsedwa kugwiritsa ntchito putty yosagwira madzi ku putty wamba mukatha kupukuta kapena kupukuta putty wamba.

(2) Putty wamba ikauma, utoto wa latex ukhoza kupakidwa utoto.

(3) Ufa wamba wamba sungagwiritsidwe ntchito m'malo omwe nthawi zambiri amakhala amdima komanso achinyezi monga zimbudzi, zipinda zapansi, zipinda zosambira, zochapira magalimoto, maiwe osambira, ndi khitchini.
