Starch ether, monga chosinthira chofunikira chamankhwala, chimagwira ntchito yofunika kwambiri pakumanga. Ndi polima yomwe imapezedwa posintha mankhwala owuma achilengedwe, omwe amatha kusintha kwambiri magwiridwe antchito a zida zomangira.
1. Basic katundu wa wowuma ethers
Starch ether ndi chinthu chopanda ayoni, chosungunuka m'madzi cha polima chokhala ndi ma hydroxyl angapo ndi ma etha pamapangidwe ake. Magulu a mankhwala awa amapatsa wowuma ethers kukhuthala kwabwino kwambiri, kusunga madzi, kuthira mafuta ndi zomatira. Malinga ndi njira zosiyanasiyana zosinthira mankhwala, ma etha wowuma amatha kugawidwa m'mitundu yosiyanasiyana monga hydroxypropyl starch ether ndi hydroxyethyl starch ether. Mitundu yosiyanasiyana ya ma ethers owuma imakhala ndi katundu ndi ntchito zosiyanasiyana.
2. Ntchito ya wowuma ether mu zomangira
Kuchulukitsa:
Pamene wowuma ether amasungunuka m'madzi, amatha kuonjezera kukhuthala kwa njira yamadzimadzi, yomwe imapangitsa kuti ikhale yogwiritsidwa ntchito ngati thickener muzomangamanga. Madera ake ofunikira kwambiri amaphatikiza ufa wa putty, zokutira ndi matope. Powonjezera wowuma etere, zomangira zikhoza kukhala bwino thixotropy ndi constructability, ndi kupewa mopitirira muyeso otaya kapena kuthetsa kwa zipangizo pomanga.
Kusunga madzi:
Starch ether ili ndi zinthu zabwino kwambiri zosungira madzi ndipo imatha kusunga chinyezi muzomangira. Izi ndizofunikira makamaka pazinthu zopangira simenti, chifukwa hydration reaction ya simenti imafuna kuchuluka kwa chithandizo cha chinyezi. Powonjezera starch ether, kusungunuka kwa madzi kumatha kuchepetsedwa ndipo simenti imatha kukhala ndi madzi okwanira, motero kumapangitsa kuti zida zomangira zikhale zolimba komanso zolimba.
Mafuta:
Wowuma ether imakhalanso ndi mafuta abwino opangira zida zomangira ndipo imatha kupititsa patsogolo ntchito yomanga ya zida. Makamaka panthawi yomanga, wowuma ether amatha kuchepetsa mkangano pakati pa zida ndi zida zomangira, kupangitsa kuti ntchito yomanga ikhale yosavuta komanso yothandiza pomanga.
Ntchito ya Bonding:
Monga ma polima apamwamba a molekyulu, starch ether ilinso ndi zinthu zina zomangira ndipo imatha kupititsa patsogolo mphamvu zomangira zomangira. Pambuyo powonjezera wowuma ether, mphamvu yomangirira mkati ndi kumamatira kwakunja kwa zinthuzo kudzakhala bwino, potero kuwongolera magwiridwe antchito onse azinthu zomangira.
3. Kugwiritsa ntchito ether wowuma muzomangamanga zinazake
Putty powder:
Kuonjezera starch ether ku putty powder kumatha kupititsa patsogolo ntchito yake yomanga komanso kusalala kwa pamwamba. Kukhuthala ndi kusunga madzi kwa wowuma ether kumapangitsa kuti ufa wa putty usagwedezeke kapena kusweka panthawi yomanga, kuonetsetsa kuti ntchito yomanga ikhale yabwino.
Zomata matailosi:
Zomatira za matailosi ziyenera kukhala zomatira bwino komanso ntchito yomanga. Kuwonjezera kwa wowuma ether kungapangitse mamasukidwe akayendedwe ndi kusunga madzi kwa zomatira matailosi, kupangitsa kuti ikhale yosalala panthawi yomanga ndikutha kumangirira mwamphamvu matailosi.
Dry mix mortar:
Kuonjezera starch ether ku matope osakaniza owuma kungathandize kuti matope asasunthike komanso kuti madzi asasungidwe, ndikuwonjezera mphamvu yake yomangirira ndi kukhazikika. Izi ndizofunikira kwambiri pazogwiritsa ntchito monga zotsekera pakhoma lakunja ndi makina otenthetsera pansi.
zokutira:
Kugwiritsiridwa ntchito kwa wowuma ether mu zokutira makamaka ngati thickener ndi madzi kusunga wothandizira kusintha rheology ndi workability wa zokutira ndi kupanga ❖ kuyanika yunifolomu ndi wokongola. Panthawi imodzimodziyo, starch ether imathanso kupititsa patsogolo ntchito ya anti-sag ya zokutira ndikuletsa kuti nsabwe zisagwedezeke panthawi yomanga.
4. Ubwino wa wowuma ether
Chitetezo cha chilengedwe:
Ma ethers owuma amachokera ku wowuma wachilengedwe, ndi wongowonjezedwanso, wowola, komanso wokonda chilengedwe. Izi zimapereka kugwiritsa ntchito ether wowuma mu zomangira zodziwikiratu zabwino zachilengedwe ndikukwaniritsa zofunikira za nyumba zobiriwira.
chitetezo:
Wowuma ether ndi wopanda poizoni komanso wopanda vuto ndipo sadzakhala ndi zotsatira zoyipa pa thanzi la munthu. Njira yake yogwiritsira ntchito ndi yotetezeka komanso yodalirika, ndipo ndi yoyenera kumadera osiyanasiyana omanga.
Kutsika mtengo:
Poyerekeza ndi zosintha zina zamankhwala, wowuma ether ali ndi zida zambiri zopangira ndipo mtengo wake ndi wotsika. Kugwiritsa ntchito kwake sikungangowonjezera magwiridwe antchito a zida zomangira, komanso kuchepetsa ndalama zonse ndikuwongolera phindu lazachuma.
5. Zochitika zachitukuko chamtsogolo
Pamene malingaliro omanga obiriwira ndi chitukuko chokhazikika akupitilira kukula, ma ethers owuma ali ndi chiyembekezo chochuluka chogwiritsidwa ntchito muzomangamanga. M'tsogolomu, ndi kupita patsogolo kwa sayansi ndi luso lamakono, ntchito ndi minda yogwiritsira ntchito starch ether idzakulitsidwanso. Mwachitsanzo, popititsa patsogolo kaphatikizidwe ka mamolekyu a starch ethers, zosinthira zogwira mtima zitha kupangidwa kuti zikwaniritse zosowa za zida zosiyanasiyana zomangira. Kuphatikiza apo, kugwiritsa ntchito ma ethers owuma muzomangamanga zanzeru ndi zida zomangira zogwirira ntchito kudzakhalanso malo opangira kafukufuku, kubweretsa zatsopano komanso chitukuko kumakampani omanga.
Monga chosinthira chofunikira chomangira, starch ether imagwira ntchito yofunika kwambiri pakumanga chifukwa chakukhuthala kwake, kusunga madzi, kuthira mafuta komanso kulumikizana. Ndi kupita patsogolo kosalekeza kwaukadaulo, kugwiritsa ntchito ether wowuma kudzakhala kokulirapo, kuthandizira ntchito yomanga kuti ikwaniritse chitukuko chokhazikika.
