Zomangira kalasicellulose etherndi chinthu chofunika kwambiri chogwiritsira ntchito mankhwala, chomwe chimagwiritsidwa ntchito kwambiri muzomangamanga, monga simenti, konkire, matope owuma, etc.
1. Mapangidwe a Chemical ndi magulu
Cellulose ether ndi polima pawiri wopangidwa ndi kusinthidwa kwa mankhwala a cellulose achilengedwe. Chigawo chake chachikulu ndi gulu la hydroxyl la cellulose losinthidwa ndi etherifying agent (monga vinyl chloride, acetic acid, etc.). Malinga ndi magulu osiyanasiyana a etherifying, amatha kugawidwa mumitundu yosiyanasiyana ya ma cellulose ethers, makamaka kuphatikiza hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC) ndi methyl cellulose (MC).
2. Kusunga madzi
Zida zomangira kalasi ya cellulose ether zili ndi zinthu zabwino kwambiri zosungira madzi, zomwe zimatha kusintha bwino mphamvu yosungira madzi yamatope ndi konkriti. Izi kumawonjezera operability wa zinthu pomanga ndi amachepetsa ang'onoang'ono ndi mphamvu kutaya chifukwa cha madzi evaporation.
3. Kukhuthala
Ma cellulose ether ali ndi zinthu zabwino zokulitsa, zomwe zimatha kuwongolera kukhathamira komanso kukhuthala kwazinthu zomangira, zomwe zimapangitsa kuti zikhale zosavuta kugwira ntchito pakumanga. Kukhuthala kumathandizira kukhazikika kwazinthu ndikupewa kukhazikika komanso kukhazikika.
4. Kuchepetsa madzi
Pamlingo wakutiwakuti,ma cellulose ethersamatha kuchepetsa kuchuluka kwa madzi mu konkire kapena matope, potero kumapangitsa mphamvu ndi kulimba kwa zinthuzo. Izi zimapangitsa kuti zikhale zofunikira kwambiri pakugwiritsa ntchito konkriti yapamwamba kwambiri.
5. Ntchito yomanga
Zipangizo zomangira zokhala ndi ma cellulose ethers zimakhala ndi ntchito yabwino pakumanga, zomwe zimatha kuwonjezera nthawi yomanga ndikuchepetsa zovuta zomangira zomwe zimayambitsidwa ndi kuyanika. Kuphatikiza apo, amathanso kukonza zomatira zamatope ndikuwonjezera kumamatira kwa zida zokutira.
6. Mng'alu kukana
Ma cellulose ether amatha kukulitsa kukana kwa matope ndi konkriti ndikuchepetsa ming'alu yobwera chifukwa cha kusintha kwa kutentha kapena kuyanika. Izi ndizofunikira kuti nyumba zikhazikike komanso kukongola kwanthawi yayitali.
7. Kusinthasintha ndi kugwirizana
Zomangamanga kalasi cellulose ethers ndi bwino yogwirizana ndi zosiyanasiyana zomangira ndipo akhoza kusakaniza simenti, gypsum, ma polima ndi zosakaniza zina popanda kukhudza ntchito yawo. Kusinthasintha kumeneku kumapangitsa ma cellulose ethers kugwiritsidwa ntchito kwambiri pantchito yomanga.
8. Kuteteza chilengedwe
Popeza zipangizo zama cellulose etherszimachokera ku ulusi wa zomera, iwonso ali ndi makhalidwe ena otetezera chilengedwe. Poyerekeza ndi ma polima ena opangidwa, cellulose ether ndiyothandiza kwambiri pakugwiritsa ntchito komanso kuwononga zinyalala.
9. Minda yofunsira
Zomangamanga kalasi cellulose ether chimagwiritsidwa ntchito zosiyanasiyana zomangira, kuphatikizapo:
Dongo louma: monga matope omangira, matope opaka, etc.
Konkire: makamaka konkire yogwira ntchito kwambiri.
Kuphimba: Kutha kugwiritsidwa ntchito popaka mkati ndi kunja kwa khoma, utoto wa latex, etc.
Zogulitsa za Gypsum: monga gypsum board ndi gypsum putty.
10. Njira zopewera kugwiritsa ntchito
Mukamagwiritsa ntchito zomangira zama cellulose ether, muyenera kulabadira mfundo izi:
Onjezerani molingana ndi chiŵerengero chovomerezeka, mopitirira muyeso kapena osakwanira zidzakhudza ntchito yomaliza.
Onetsetsani kufanana pakusakaniza kuti musagwirizane.
Mukamasunga, samalani ndi chinyezi kuti musamakhale ndi chinyezi komanso kusanjikana.
Zomangamanga zama cellulose ether zakhala chowonjezera chofunikira kwambiri pamakampani opanga zida zomangira chifukwa cha mawonekedwe ake apadera komanso kugwiritsa ntchito kwake. Ndi kusintha kosalekeza kwa zofunikira zamakampani omanga kuti zigwire ntchito, chiyembekezo chogwiritsa ntchito cellulose ether chidzakhala chokulirapo.
