Pogwiritsa ntchito cellulose kwambiri hpmc (hydroxypropyl methylcellulose) mu matope a simenti ali ndi zabwino zambiri, zomwe zimapangitsa HPMC kukhala kothandiza kwambiri pantchito zomanga. HPMC makamaka imagwira ntchito yokulirapo, kusungidwa kwamadzi, kugwiritsa ntchito matope a simenti, potero ndikuwongolera magwiridwe antchito omaliza.
1. Kusunga kwamadzi
Kusunga kwamadzi kwa HPMC ndi chimodzi mwazinthu zofunika kwambiri. Mu matope a simenti, kusungulumwa kwamadzi kumatanthauza kuthekera kwa zinthuzo kuti zisunge chinyontho. Izi zimakhudza kwambiri matope. HPMC imatha kuchepetsa kuchepa kwamadzi nthawi yomanga ndikuwonjezera kusunga kwamadzi kwa matope, potero kuonetsetsa kuti ntchito za matope. Ubwino waukulu wa madzi umaphatikizapo:
Kutalikirana Nthawi: Popeza madzi amatuluka pang'onopang'ono, omanga omanga amakhala ndi nthawi yambiri yosintha ndi kukonza matope, makamaka kutentha kwambiri kapena malo ouma mpweya.
Pewani kuwonongeka: Panthawi yolimba, kutayika pang'onopang'ono kwa madzi ndikomwe kumayambitsa matope. HPMC imatha kusunga madzi mokwanira ndikuchepetsa kupezekanso kwa ming'alu ya shrad.
Sinthani mtundu wa kukonza: Kusungidwa kwabwino kwamadzi kumatsimikizira kuti simenti ili ndi madzi okwanira pakukonzekera kwa nthawi yayitali, potero kumalimbikitsa mphamvu yomaliza, yokhazikika ya simenti.
2. Kupanga magwiridwe antchito
Kuwongolera magwiridwe antchito ndi gawo lina lalikulu la HPMC mu matope a simenti. Makamaka:
Sinthani Kusasinthika: HPMC imatha kuwonjezera matope a matope, ndikupangitsa kuti ikhale yosavuta kufalitsa ndi kukhala ndi malire pomanga, zomwe ndizofunikira kwambiri pazogwiritsa ntchito ngati khoma lopaka ndi pansi.
Kuthira mafuta: HPMC imatha kuchepetsa mikata ya matope, kupanga matontho matope bwino pamaziko omanga, kukonza njira zomangira zomangira komanso kuchepetsa zida.
Anti-Sagging: Mukamamanga malo owongoka, hpmc imatha kukonza bwino zotsatsa komanso zotsutsana ndi matope a matope, kupewa matope kuchokera kutsika kapena kutuluka chifukwa cha mphamvu yokoka.
3. Zomata zomata
HPMC imapereka simenti ya simenti yabwino kwambiri yomatira, yomwe ndiyofunika kwambiri kwa matope ena apadera (monga matayala a tiles, kukonza matope, etc.):
Kupititsa patsogolo: kuwonjezera kwa HPMC kumatha kupanga mphamvu yolumikizana pakati pa matope ndi gawo lapansi, potero kukonza zomangira za matope.
Kuchepetsa kukhetsa: zomwe zimapangitsa kuti zikhale bwino zitha kulepheretsa zotsatsa kuti zisagwetsere ndi kukhetsa pomwe kuli kouma kapena kupsinjika.
Onjezani mphamvu yometa ubweya: M'mapulogalamu ena omwe amafunikira kuthana ndi nkhawa kwambiri, hpmc amatha kukulitsa chimbudzi chakumwa cha matope, potero kukonza bata lonse la kapangidwe kake.
4. Kupititsa patsogolo zochitika zomanga
Ubwino Wosintha Zinthu Zomanga ndi chimodzi mwa zifukwa zomwe HPMC ndi yotchuka kwambiri, makamaka nyengo yovuta, kugwiritsa ntchito HPMC ndikofunika kwambiri:
Ubwino Wamtengo Wapamwamba Wakutentha: HPMC imatha kuchepetsa kusintha kwamadzi kwa madzi ambiri, potero ndikutsegulira nthawi ndi nthawi yolerera matope.
Ubwino wozizira: Zimathandizanso kuti madziwo mu matope ozizira msanga, potero amateteza hydrate chitani chiwongolanthe.
5. Kukhazikika kwamphamvu
Kugwiritsa ntchito HPMC kumatha kukulitsa kukhazikika kwa matope a simenti:
Sinthani zolimbana: Pogwiritsa ntchito matope a simenti, hpmc moyenera zimachepetsa pang'ono ndikuuma, potero mwakuthandizani kukhazikika kwa nthawi yayitali matombi.
Kuchulukitsa kukana kuzungulira kwaming'alu: hpmc kumatha kuchepetsa kupezeka kwa ming'alu pachimato komwe kumayambitsidwa ndi ming'alu yaulere ndikusunganso umphumphu wa nkhaniyi.
Alkalinity Kukana: Mu mapulogalamu ena apadera, hpmc amatha kupereka digiri yolimbana ndi alkali kuti iteteze matope a simenti kuchokera kwa alkali-argegate.
6. Magwiridwe antchito
HPMC ndi zinthu zosangalatsa zachilengedwe zomwe sizingavulaze ogwira ntchito zomanga ndi chilengedwe:
Osakhala oopsa komanso osavulaza: hpmc ndi ethel ether ether ether yomwe sikuti ndi poizoni komanso yovulaza kwa thupi la munthu ndi chilengedwe.
Zowonongeka: HPMC ndi biodegradgle ndipo sizingapangitse kuipitsidwa kwa nthawi yayitali kudziko lapansi.
7. Zachuma
Ngakhale mtengo wa HPMC ndi wokwera kwambiri, umunthu wake umawonetsedwa mu njira yomanga yomanga kwambiri komanso mtundu womaliza:
Kuchepetsa ntchito
Sungani zida: Kugwiritsa ntchito mphamvu kwa matope komanso kuphatikiza katundu kumachepetsa zinyalala zakuthupi, ndikugwiritsa ntchito HPMC yochulukirapo yachuma.
Kusankha ndi kugwiritsa ntchito HPMC
Mukamasankha HPMC, ndikofunikira kulinganiza magawo monga mafakiti, kuchuluka kwa zolowa m'malo mwake, ndi kukula kwa tinthu. Zinthu izi zimakhudza mwachindunji makonzedwe a HPMC mu matope a simenti:
Makulidwe: Makulidwe apamwamba nthawi zambiri amabweretsa chisungiko chamadzi komanso ntchito zomanga, koma zitha kuchepetsa kubisala kwa matope. Chifukwa chake, ndikofunikira kusankha kalasi yoyenera yoyenera malinga ndi pulogalamu inayake.
Mlingo wa zolowa m'malo: Mlingo wazolowa zomwe zimakhudza kusoka ndi magwiridwe antchito a HPMC. Madigiriti oyenera a cholowa chitha kuwonetsetsa kuti magawidwe a yunifolomu komanso ntchito ya hpmc mu matope.
Kukula kwa tinthu: kukula kwa tinthu tating'ono kumatha kupanga HPMC mosavuta kusakanikirana ndi matope ndikusintha.
Kugwiritsa ntchito kwa cellulose kwambiri mu cent mu simenti kumathandizira kukonza madzi osungirako madzi, zomangamanga, kugwira ntchito ndi chikhazikitso cha matope, pomwenso kukonza mikhalidwe yomanga ndi chuma. Kugwiritsa ntchito kwake kumatha kuchepetsa mavuto moyenera monga kusokonekera ndikugwa pamatope, kukulitsa moyo wankhaniyo, ndikupereka njira yochezera zachilengedwe. M'madera amakono, HPMC yawonjezera zowonjezera, ndikupereka thandizo kofunikira kukonza magwiridwe antchito ndikuwonetsetsa kuti zomangamanga.
