Ma cellulose ethers ndi gulu lofunikira la zowonjezera zowonjezera, zomwe zimagwiritsidwa ntchito kwambiri popanga zida zomangira kuti zithandizire kukonza magwiridwe antchito. Makamaka mu zomatira matailosi, ma cellulose ether amatha kusintha kwambiri mawonekedwe awo akuthupi ndi mankhwala, kupititsa patsogolo ntchito yomanga, komanso kukulitsa mphamvu zomangira ndi kulimba.
1. Zinthu zofunikira za cellulose ethers
Ma cellulose ethers ndi zotumphukira zomwe zimapezedwa ndi kusinthidwa kwa mankhwala a cellulose yachilengedwe, ndipo zodziwika bwino zimaphatikizapo methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), hydroxyethyl cellulose (HEC), etc. Makhalidwewa amapangitsa kuti ma cellulose ether azigwira ntchito yofunika kwambiri pazomatira matailosi.
2. Kusunga madzi bwino
2.1 Kufunika kosunga madzi
Kusungidwa kwamadzi kwa zomatira matailosi ndikofunikira kuti ntchito yomanga igwire bwino ntchito komanso mphamvu yomangirira. Kusungidwa bwino kwa madzi kumatha kuwonetsetsa kuti zomatirazo zimakhala ndi chinyezi choyenera panthawi yochiritsa, potero zimatsimikizira kuti simenti imakwanira bwino. Ngati kusungirako madzi sikukwanira, madzi amatengedwa mosavuta ndi gawo lapansi kapena chilengedwe, zomwe zimapangitsa kuti hydration ikhale yosakwanira, yomwe imakhudza mphamvu yomaliza ndi kugwirizana kwa zomatira.
2.2 Njira yosungira madzi ya cellulose ether
Ma cellulose ether ali ndi mphamvu yosungira madzi kwambiri ndipo amatha kumanga mamolekyu ambiri amadzi pa tcheni chake. Kuthamanga kwake kwamadzi amadzimadzi kungapangitse kugawa kwamadzi yunifolomu mu zomatira ndikutseka madzi kudzera muzitsulo za capillary muzitsulo zomatira kuti madzi asatayike mofulumira. Njira yosungira madzi iyi sikuti imangothandiza kuti simenti iwonongeke, komanso imatha kuwonjezera nthawi yotseguka ya zomatira ndikuwongolera kusinthika kwa zomangamanga.
3. Kupititsa patsogolo ntchito yomanga
3.1 Kuonjezera nthawi yotsegula
Kuyamba kwa cellulose ether kumawonjezera nthawi yotseguka ya zomatira matailosi, ndiko kuti, nthawi yomwe zomatira zimakhalabe zomata zitagwiritsidwa ntchito pa gawo lapansi. Izi zimapatsa ogwira ntchito yomanga nthawi yochulukirapo kuti asinthe ndikuyika matailosi, potero amachepetsa kuwonongeka kwa zomangamanga komwe kumachitika chifukwa cha kuthamanga kwa nthawi.
3.2 Kuchita bwino kwa anti-sagging
Panthawi yomanga, zomatira zimatha kugwedezeka chifukwa cha mphamvu yokoka matailosi atayikidwa, makamaka akagwiritsidwa ntchito pamtunda. Kuchulukana kwa cellulose ether kumatha kupititsa patsogolo zomatira zomata, kuonetsetsa kuti sizikugwedezeka potsatira matailosi. Katunduyu ndi wofunikira kwambiri pakuwonetsetsa kulondola komanso kukongola kwathunthu pakuyika matailosi.
3.3 Kupititsa patsogolo mafuta ndi kagwiritsidwe ntchito
Kupaka mafuta a cellulose ether kumapangitsa kuti zomatira za matailosi zizigwira ntchito bwino, kuti zikhale zosavuta kuziyika komanso kuphwanyidwa. Katunduyu amathandizira kuchepetsa zovuta komanso nthawi yomanga ndikuwongolera ntchito yomanga.
4. Limbikitsani mphamvu ya mgwirizano
4.1 Kupititsa patsogolo kumamatira koyamba
The mkulu mamasukidwe akayendedwe njira yopangidwa ndi mapadi etere mu amadzimadzi njira kuonjezera zomatira koyamba matailosi zomatira, kupereka mwamsanga adhesive pamene akuyala matailosi ndi kupewa matailosi kutsetsereka kapena dislocation.
4.2 Limbikitsani kuchuluka kwa simenti
Kuchita bwino kwa madzi osungiramo madzi a cellulose ether kumapangitsa kuti simenti ikhale yokwanira, motero imapanga zinthu zambiri za hydration (monga hydrated calcium silicate), zomwe zimapangitsa kuti zomatira zikhale zolimba. Izi sizimangowonjezera mphamvu zamakina za zomatira, komanso zimakulitsa kulimba kwake komanso kukana kwa ming'alu.
5. Kupititsa patsogolo kukhazikika ndi kukana ming'alu
5.1 Kupititsa patsogolo kukana kuzizira
Ma cellulose ethers amathandizira kuti zomatira za matailosi azizizira poundana mwa kukonza kusunga madzi komanso kuphatikizika kwa zomatira za matailosi, kuchepetsa kusamuka mwachangu komanso kutayika kwa madzi. Kusintha kumeneku kumapangitsa kuti zomatira zizikhala zokhazikika ngakhale m'malo ozizira kwambiri ndipo sizingathe kusweka kapena kusweka.
5.2 Kupititsa patsogolo kukana kwa crack
Pakuchiritsa kwa zomatira, mawonekedwe a netiweki wandiweyani opangidwa ndi cellulose ethers amathandizira kuchepetsa kuchepa kwa simenti ndikuchepetsa chiopsezo chosweka chifukwa cha kupsinjika kwa shrinkage. Kuphatikiza apo, kukhuthala kwa ma cellulose ethers kumathandizira zomatira kudzaza bwino kusiyana pakati pa matailosi ndi gawo lapansi, kupititsa patsogolo kukhazikika kwa mawonekedwe omangira.
6. Ntchito zina
6.1 Perekani mafuta ndi anti-sagging katundu
Kupaka mafuta a cellulose ether sikungothandiza kugwira ntchito, komanso kumachepetsa zochitika zomatira panthawi yogwiritsira ntchito, kuonetsetsa kufanana ndi kukhazikika panthawi yogwiritsira ntchito.
6.2 Kupititsa patsogolo ntchito zomanga
Powonjezera kukhuthala ndi nthawi yomanga ya zomatira, cellulose ether imapangitsa kuti ntchito yomanga ikhale yabwino, kulola ogwira ntchito yomanga kusintha malo a matailosi mosavuta, kuchepetsa kuwonongeka kwa zomangamanga ndi mitengo yokonzanso.
7. Zitsanzo za Kugwiritsa Ntchito Ma cellulose Ether
M'mapulogalamu apadera, cellulose ether imapangitsa kuti ntchito yonseyo ikhale yabwino popititsa patsogolo ntchito zomatira matailosi. Mwachitsanzo, m'malo ena otentha kapena otsika chinyezi, zomatira wamba zimatha kukumana ndi vuto la kutaya madzi mwachangu, zomwe zimapangitsa kuti pakhale zovuta zomanga komanso kusakwanira kwamphamvu. Pambuyo powonjezera cellulose ether, zomatira zimatha kusunga madzi abwino, kupewa mavutowa, motero kuonetsetsa kuti ntchitoyo ndi yabwino.
Ma cellulose ether amathandizira kwambiri magwiridwe antchito a zomatira matailosi kudzera pakusungirako bwino kwa madzi, kukhuthala ndi kuyanika. Sikuti zimangowonjezera ntchito yomanga, mphamvu zomangirira ndi kulimba kwa zomatira, komanso zimapangitsa kuti zomangamanga zikhale zosavuta komanso zodalirika. Kusintha kumeneku sikungowonjezera ubwino wonse wa polojekitiyi, komanso kumapereka kusinthasintha kwakukulu ndi kukhazikika kwa ntchito yomanga. Chifukwa chake, monga chowonjezera chachikulu, kugwiritsa ntchito cellulose ether mu zomatira matailosi kuli ndi phindu lofunikira komanso chiyembekezo chachikulu.
