Bentonite ndi polima slurries amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, makamaka pobowola ndi kumanga. Ngakhale zili ndi ntchito zofananira, zinthuzi zimasiyana kwambiri pakupanga, katundu ndi ntchito.
Bentonite:
Dongo la Bentonite, lomwe limatchedwanso dongo la montmorillonite, ndi zinthu zachilengedwe zomwe zimachokera ku phulusa lamapiri. Ndi smectite yamtundu wa dongo yomwe imadziwika ndi kutupa kwake kwapadera ikakhala ndi madzi. Chigawo chachikulu cha bentonite ndi mchere wa montmorillonite, womwe umapatsa katundu wake wapadera.
ntchito:
Dongo la Bentonite limapangidwa makamaka ndi montmorillonite komanso lili ndi mchere wosiyanasiyana monga quartz, feldspar, gypsum, ndi calcite.
Mapangidwe a montmorillonite amalola kuti amwe madzi ndi kutupa, kupanga chinthu chonga gel.
chikhalidwe:
Kutupa: Bentonite imawonetsa kutupa kwakukulu ikathiridwa madzi, zomwe zimapangitsa kuti zikhale zothandiza kusindikiza ndi plugging ntchito.
Viscosity: The mamasukidwe akayendedwe a bentonite slurry ndi apamwamba, kupereka kuyimitsidwa wabwino ndi cuttings kunyamula luso pa kubowola.
ntchito:
Madzi Oboola: Dongo la Bentonite limagwiritsidwa ntchito kwambiri pobowola matope popanga zitsime zamafuta ndi gasi. Zimathandizira kuziziritsa ndi kuthira mafuta pobowola ndikubweretsa tchipisi pamwamba.
Kusindikiza ndi Kumanga: Kutupa kwa Bentonite kumalola kuti atseke bwino mabowo ndikuletsa kusamuka kwamadzi.
ubwino:
Chilengedwe: Dongo la Bentonite ndi zinthu zachilengedwe zomwe zimachitika mwachilengedwe.
Mtengo wake: Nthawi zambiri imakhala yotsika mtengo kuposa njira zopangira.
zoperewera:
Kutentha kwapang'onopang'ono: Bentonite ikhoza kutaya mphamvu yake pa kutentha kwakukulu, kuchepetsa kugwiritsidwa ntchito kwake pazinthu zina.
Kukhazikitsa: Kuthamanga kwambiri kwa bentonite slurry kungayambitse kukhazikika ngati sikuyendetsedwa bwino.
Polima slurry:
Polymer slurries ndi zosakaniza zamadzi ndi ma polima opangidwa kuti akwaniritse magwiridwe antchito. Ma polima awa adasankhidwa chifukwa cha kuthekera kwawo kupititsa patsogolo mawonekedwe a slurry pazogwiritsa ntchito zina.
ntchito:
Ma polima slurries amapangidwa ndi madzi ndi ma polima osiyanasiyana opangidwa monga polyacrylamide, polyethylene oxide, ndi xanthan chingamu.
chikhalidwe:
Kusatupa: Mosiyana ndi bentonite, slurry ya polima simatupa pamene imalowa m'madzi. Amasunga mamasukidwe akayendedwe popanda kusintha kwakukulu kwa voliyumu.
Kumeta ubweya wa ubweya: Ma polima slurries nthawi zambiri amawonetsa kumeta ubweya wa ubweya, zomwe zikutanthauza kuti kukhuthala kwawo kumachepa chifukwa cha kumeta ubweya, zomwe zimathandizira kupopa ndi kuzungulira.
ntchito:
Trenchless Technology: Matope a polima amagwiritsidwa ntchito pobowola mopingasa (HDD) ndi ntchito zina zopanda ma trenchless kuti apereke bata komanso kuchepetsa mikangano.
Kumanga: Amagwiritsidwa ntchito m'makoma a diaphragm, makoma a slurry ndi ntchito zina zomanga kumene kukhuthala kwamadzimadzi ndi kukhazikika ndizofunikira.
ubwino:
Kukhazikika kwa kutentha: Ma polymer slurries amatha kusunga katundu wawo pamatenthedwe apamwamba, kuwapangitsa kukhala oyenera kugwiritsa ntchito mosiyanasiyana.
Mafuta owonjezera: Zomwe zimapaka mafuta a polymer slurries zimathandizira kuchepetsa kuvala kwa zida zoboola.
zoperewera:
Mtengo: Polima slurry akhoza kukhala okwera mtengo kuposa bentonite, malingana ndi polima yomwe imagwiritsidwa ntchito.
Kukhudza Kwachilengedwe: Ma polima ena opangira amatha kukhala ndi zovuta zachilengedwe zomwe zimafunikira njira zoyenera zotayira.
Pomaliza:
Ngakhale kuti bentonite ndi ma polima slurries ali ndi ntchito zofanana m'mafakitale, kusiyana kwawo, katundu ndi ntchito zimawapangitsa kukhala oyenera pazochitika zosiyanasiyana. Kusankha pakati pa bentonite ndi polima slurry zimadalira zofunikira zenizeni za polojekiti yomwe yapatsidwa, poganizira zinthu monga mtengo, chilengedwe, kutentha ndi zofunikira zogwirira ntchito. Mainjiniya ndi akatswiri akuyenera kuwunika mosamala zinthu izi kuti adziwe zida zoyenera kugwiritsa ntchito zomwe akufuna.
