Mphamvu ya cellulose ether pazinthu za simenti

Zida zopangira simenti zimagwiritsidwa ntchito kwambiri pantchito yomanga. Zidazi, zomwe nthawi zambiri zimaphatikiza simenti, mchenga, madzi ndi zophatikizika, zimakhala ndi mphamvu zolimba komanso zopondereza, zomwe zimawapangitsa kuti azikonda zomanga ndi zomangamanga. Komabe, kugwiritsa ntchito ma cellulose ethers monga zowonjezera kuzinthu zopangira simenti kumatha kusintha kwambiri katundu wawo, makamaka kulimba kwawo, kugwirira ntchito kwawo komanso kuyenda. Ma cellulose ethers ndi ma carbohydrate osinthidwa opangidwa kuchokera ku cellulose, chigawo chachikulu cha makoma a cell ya zomera.

Kukhalitsa

Kukhazikika kwa zinthu zopangidwa ndi simenti ndizofunikira kwambiri pakumanga, makamaka pazovuta zachilengedwe. Chifukwa cha zomwe zimasunga madzi, ma cellulose ether amatha kupititsa patsogolo kulimba kwa zinthuzi. Pawiriyi imapanga mgwirizano wakuthupi ndi wamankhwala ndi madzi, zomwe zimathandiza kuchepetsa kutayika kwa chinyezi kudzera mu nthunzi ndikuwongolera njira yochiritsa. Chotsatira chake, zida za simenti zimakhala zolimba kwambiri kusweka kapena kuchepa, zomwe ndizofunikira kuti zitsimikizidwe kuti zikhazikitsidwe kwa nthawi yayitali. Kuphatikiza apo, ma cellulose ether amatha kusintha kukana kwa simenti kumaundana mwa kuletsa madzi kulowa mu pores, potero amachepetsa chiwopsezo cha kuwonongeka kwa kuzizira kozizira.

Kuthekera

Kugwira ntchito kwa zinthu zopangidwa ndi simenti kumatanthawuza kutha kwake kusakanikirana, kuthiridwa, ndi kuphatikizika popanda kupatukana kapena kukhetsa magazi. Zowonjezera za cellulose ether zimatha kupititsa patsogolo kusinthika kwa zinthu izi, kuzipangitsa kuti zikhale zosavuta kuzigwira ndikuwongolera pakumanga. Pulogalamuyi imagwira ntchito ngati thickener ndi stabilizer, kupititsa patsogolo mgwirizano ndi kusasinthasintha kwa zipangizo zopangira simenti. Kuwongolera kogwira ntchito kumeneku kumapangitsa kuti pakhale kuwongolera kwakukulu pakuyenda kwa zinthu, kuonetsetsa kuti zitha kutsanuliridwa mu mawonekedwe ofunikira ndi mawonekedwe popanda kutaya kukhulupirika kwake. Kuphatikiza apo, ma cellulose ethers amatha kupititsa patsogolo kutulutsa kwazinthu zopangira simenti, kuwalola kuti azinyamulidwa mosavuta kudzera pa mapaipi ndi mapaipi.

Yendani

Kuyenda ndi kofunika kwambiri pa zipangizo zopangira simenti, makamaka pa konkriti yodzipangira yokha, kumene kusasinthasintha ndi kutuluka kwake ndizofunikira kwambiri. Ma cellulose ethers amatha kupititsa patsogolo kuyenda kwa zinthu zopangira simenti kuti zitheke kukhazikika, zomwe zimapindulitsa kuchepetsa mapangidwe amatumba a mpweya kapena thovu muzinthuzo. Pawiriyi imagwira ntchito ngati rheology modifier, kuwongolera mawonekedwe azinthu zopangira simenti popanda kukhudza makina awo. Chifukwa chake, zida zopangira simenti zomwe zili ndi ma cellulose ether zimatha kuphimba kwambiri ndikumaliza pamwamba.

Pomaliza

Kuonjezera ma cellulose ether kuzinthu zopangidwa ndi simenti kungathandize kukonza ndi kukulitsa katundu wawo. Imawongolera kulimba, kugwirira ntchito komanso kusuntha kwa zinthu zopangidwa ndi simenti, zomwe zimapangitsa kuti zikhale zowonjezera pazomangamanga. Pawiriyi imasunga chinyezi, imapangitsa kuti simenti ikhale yabwino, komanso imachepetsa chiopsezo cha kusweka ndi kuchepa. Kuonjezera apo, ma cellulose ethers amatha kupititsa patsogolo mgwirizano ndi kusinthasintha kwa zipangizo zopangira simenti, zomwe zimathandiza kuti pakhale kuwongolera bwino kwa zinthu zomwe zikuyenda, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito pomanga. Choncho, kugwiritsa ntchito ma cellulose ethers popanga zinthu zopangidwa ndi simenti kungabweretse zotsatira zabwino komanso zopindulitsa.
