Matate ndi pulasitala ndi zinthu zotchuka zomwe zimagwiritsidwa ntchito kwambiri m'makampani omanga. Ndikofunikira pakukonzekeretsa makhoma ndi kudenga zojambula, kuphimba ming'alu, kukonza zowonongeka, ndikupanga malo osalala, ngakhale pamalo. Amakhala ndi zosakaniza zosiyanasiyana kuphatikiza simenti, mchenga, laimu ndi zina zowonjezera kuti zithandizire magwiridwe antchito ndi mawonekedwe. Methylhydroxyelycellulose (mahec) ndi imodzi mwazowonjezera zazikulu zomwe zimagwiritsidwa ntchito popanga purty ndi plaster ufa. Amagwiritsidwa ntchito kukonza zinthu za ufa, zimawonjezera katundu wawo ndikumalimbikitsa mapulogalamu awo.
Ubwino Wogwiritsa Ntchito Mhec kuti apange ufa ndi gypsum ufa
Miche amachokera ku cellulose ndikupanga kudzera pakusintha kwamankhwala. Ndi malo osungunuka osungunuka kwambiri ogwiritsidwa ntchito ngati Thicner, okhazikika ndi emulsifier mu makampani omanga. Mukawonjezeredwa ku purty ndi gypsum ufa, anc amaphimba tinthu tating'onoting'ono, ndikupatsanso chosakanizira chomwe chimawalepheretsa kutsitsa ndikukhazikika. Izi zimabweretsa masanjidwenso osakanikirana kwambiri omwe ndi osavuta kugwira nawo ntchito komanso amaperekanso kumaliza.
Chimodzi mwazopindulitsa kwakukulu pakugwiritsa ntchito mayc mu zoikapo ndi zigawo ndikuti zimawonjezera nthaka yawo yosungira madzi. Anac amatenga ndikusunga chinyezi, ndikuonetsetsa kusakaniza kumakhalabe kosagwira ndipo sikuwuma mwachangu kwambiri. Izi ndizofunikira makamaka m'malo otentha komanso owuma pomwe osakaniza msanga amakhala osasinthika, zomwe zidatsimikizika.
Mhec amathandizanso kugwiritsa ntchito ntchito komanso nthawi yogwira ntchito ndi ziphuphu. Mic imapanga kusakanikirana ndikugwiritsa ntchito zosakaniza mosasakaniza posunga chinyezi ndikuletsa kusakaniza kosakanikirana. Kuphatikiza apo, mawonekedwe osalala a Mhec amalola putty ndi Stucco kuti afalikira pomwepo popanda kusiya zotupa kapena zotupa, ndikumaliza.
Kuphatikiza pa kukulitsa mawonekedwe ndi kugwirira ntchito kwa matikiti ndi ma gustersters, magec amathanso kukonza mgwirizano. Mwa kupanga malo otetezera mozungulira tinthu tating'onoting'ono ,.bchi amawonetsetsa kuti amalumikizana bwino pamalo omwe akuchiritsa. Izi zimapangitsa kuti pakhale pansi mwamphamvu kwambiri, zolimba kwambiri zomwe sizingatheke kusweka, chip kapena peel pakapita nthawi.
Ubwino wina wofunika wogwiritsa ntchito macheti ndi pulasitala ndi kuti zimawonjezera kukana kwawo kwa mpweya ndi chinyezi. Izi zikutanthauza kuti kamodzi kapena stucco ikugwiritsidwa ntchito, idzakana kuwonongeka kwa mpweya ndi chinyezi, kuonetsetsa kuti izikhala zolimba komanso zokongola.
Kukonzanso ma protty ndi gypsum magwiridwe antchito a Mic
Kuti muchepetse ntchito ya putty ndi pulasitala ya pulasitiki, ndikofunikira kuwonetsetsa kuti Mic imagwiritsidwa ntchito poyerekeza kolondola. Izi zikutanthauza kuti kugwiritsa ntchito kuchuluka kolondola kwa Miche kungakwaniritse magwiridwe antchito ndi mawonekedwe a punty kapena a Stucco.
Zinthu zomwe zingakhudze magwiridwe ake a purty ndi gypsum ufa ziyenera kuganiziridwa. Mwachitsanzo, m'malo otentha ndi owuma, ambiri a moc angafunike kuwonjezeredwa kuti asankhe zosakanikirana.
Ndikofunikira kuonetsetsa kuti putty kapena stuccoko imagwiritsidwa ntchito moyenera kuti ipititse magwiridwe ake. Izi zikutanthauza kutsatira malangizo a wopanga mosamala ndikuonetsetsa kuti osakaniza amasakanizidwa bwino musanagwiritse ntchito. Kuphatikiza apo, zida zapadera zitha kufunidwa kuonetsetsa kuti putty kapena Stuccous imagwiritsidwa ntchito mozama komanso mosinthasintha kuti apatsidwe.
Mic ndi gawo lofunikira logwiritsidwa ntchito popanga punty ndi plaster ufa. Zimawonjezera katundu ndi katundu wa zinthuzi, kukonza masinthidwe awo, kusungidwa kwamadzi, kutsatira ndi kukana mpweya ndi chinyezi. Izi zimapangitsa kutsiriza kofananako komanso kokhazikika komanso kowoneka bwino komwe sikungatheke kuphwanya, chip kapena peel pakapita nthawi. Pofuna kukonza magwiridwe a purty ndi gypsum ufa, ndikofunikira kuwonetsetsa kuti mlingo woyenera wa mathec umagwiritsidwa ntchito, poganizira zinthu zachilengedwe zomwe zingasokoneze magwiridwe awo. Kuphatikiza apo, ndikofunikira kugwiritsa ntchito putty kapena stucco moyenera kuti muchepetse ntchito yake ndikukwaniritsa zotsatira zomwe mukufuna.
Hemc imagwiritsidwa ntchito mu simenti kupanga mapangidwe ake hydroxethyl methylcellulose (hemc) ndi mankhwala omwe amagwiritsidwa ntchito mu makampani omanga. Ili ndi kulumikizana pakati pa kugwirira ntchito, kusungidwa kwamadzi, thixotropy, etc. masiku ano, mtundu watsopano wa ethel ether ether ether ether akulandila chidwi kwambiri. Zomwe zakopa chidwi chambiri ndi hydroxyethyl methylcellulose (Miche).
Chimodzi mwazinthu zofunikira kwambiri zomwe zimatsimikizira mtundu wa zinthu za simenti ndizothandiza kwa osakaniza. Umu ndi momwe simenti yosavuta simenti yosavuta, mawonekedwe ndi malo. Kuti izi zitheke, osakaniza simenti ayenera kukhala madzi okwanira kutsanulira ndikuyenda mosavuta, koma muyenera kukhala mawonekedwe okwanira kuti aletse mawonekedwe. Mic imatha kukwaniritsa katunduyu pakukulitsa mafayilo a simenti, motero amasintha.
Amayi amathanso kugwiranso ntchito hydration simenti ndikusintha mphamvu yake. Mphamvu yomaliza ya simenti imatengera kuchuluka kwa madzi omwe amagwiritsidwa ntchito kusakaniza. Madzi ochuluka kwambiri amachepetsa mphamvu ya simenti, pomwe madzi ochepa kwambiri adzapangitsa kuti zikhale zovuta kugwira nawo. Komabe, a Bec amathandiza kusunga madzi ena, ndikuwonetsetsa kuti simenti ya simenti ndikulimbikitsa kupanga mapangidwe amphamvu pakati pa tinthu tambiri.
Mic amathandizira kuchepetsa kuchuluka kwa ming'alu ya simenti. Monga momwe simenti imachirikiza, osasunthika, omwe angayambitse mawonekedwe a ming'alu ngati shrinks sulamulidwa. Mache amaletsa izi ndikusunga madzi oyenera mu kusakaniza, pomwepo amaletsa simenti kuti asakayake.
Amayi amagwiranso ntchito ngati filimu yoteteza pamtundu wa simenti pamtunda, kupewa madzi kuti asakaoneke kuchokera pamwamba. Kanemayu amathandizanso kusunga chinyezi choyambirira cha simenti, kuphatikiza mwayi wothana.
Mic ndiwothandizanso chifukwa cha chilengedwe. Choyamba, ndi biodeggerad, zomwe zikutanthauza kuti sizikhala m'malo okhazikika. Kachiwiri, zitha kuthandiza kuchepetsa kuchuluka kwa simenti yofunikira pantchito zomanga. Izi ndichifukwa choti mahec imawonjezera kugwirira ntchito komanso mafayilo a simenti, kuchepetsa kufunika kwa madzi owonjezera omwe amachepetsa kusakaniza kwa simenti.
Kugwiritsa ntchito mathec mu simenti kumapereka zabwino zambiri ndipo kumatha kuyambitsa zomangamanga. Zimawonjezera kugwiritsidwa ntchito kwa osakaniza simenti, kumachepetsa kuchuluka kwa ming'alu wopangidwa mukachiritsa, kumalimbikitsa madementi hydration ndi mphamvu, ndipo amachita ngati filimu yoteteza pamtunda. Kuphatikiza apo, mahec ndi abwino kuchilengedwe. Chifukwa chake, machec ndi chinthu chamtengo wapatali chopangira mafakitale omanga pomwe chimasintha simenti ndipo chimapereka phindu kwa ogwira ntchito komanso chilengedwe.
