Ma cellulose ethers ndi mtundu wa polima pawiri wopangidwa ndi kusintha mankhwala a cellulose. Amakhala ndi mawonekedwe apadera akuthupi ndi amankhwala ndipo amagwiritsidwa ntchito kwambiri pazomatira zosiyanasiyana. Chifukwa cha zinthu zabwino kwambiri za cellulose ether, kugwiritsa ntchito zomatira sikumangowonjezera magwiridwe antchito a chinthucho, komanso kumabweretsa kusintha kwapang'onopang'ono monga kukhazikika, kukhuthala, kusunga madzi, komanso mafuta.
1. Kunenepa kwambiri
Imodzi mwa ntchito zazikulu za cellulose ethers ndikukhuthala, zomwe zimawapangitsa kukhala ofunikira kwambiri pamakina omatira amadzi. Kukhuthala kwa zomatira ndizofunika kwambiri pakugwiritsa ntchito kwake, ndipo ma cellulose ether amatha kukulitsa kukhuthala kwa zomatira popanga mawonekedwe a netiweki a cellulose. Ma cellulose ethers monga hydroxypropyl methylcellulose (HPMC) ndi hydroxyethyl cellulose (HEC) ali ndi zotsatira zabwino za thickening, ndipo katundu wawo wa thickening akhoza kusinthidwa ndi kusintha kwa kulemera kwa maselo, digiri ya m'malo ndi zina. Zomatira zokhuthala sizimangothandizira zokutira, komanso zimawonjezera mphamvu zomangira, zomwe zimapangitsa kuti zizigwiritsidwa ntchito kwambiri pazomatira zomangira, zomatira zamapepala, ndi zina zambiri.
2. Perekani madzi osungira
Kusunga madzi ndi ntchito ina yofunika ya ma cellulose ethers mu zomatira. Ma cellulose ethers ndi oyenera makamaka zomatira zamadzi, zomwe zimatha kusunga chinyezi ndikuletsa colloid kuti iume mwachangu. Izi ndizofunikira makamaka m'malo omwe chinyezi chimasanduka nthunzi mwachangu. Mwachitsanzo, mu zomatira za simenti kapena gypsum m'makampani omangamanga, ma cellulose ethers amatha kuyamwa madzi, kukulitsa ndi kupanga filimu ya hydration, kukulitsa nthawi yogwira ntchito ya zomatira ndikuwonetsetsa kuti chitetezo chikugwira ntchito yomanga. Zomangamanga sizimawonongeka ndi kuyanika msanga. Izi zimagwiranso ntchito kumadera monga kupenta pakhoma ndi zomatira matailosi zomwe zimafunika kuwongolera kutuluka kwamadzi.
3. Limbikitsani kugwirizana ndi kumamatira katundu
Kuphatikizika kwa cellulose ether sikungokulitsa ndikusunga madzi, komanso kumapangitsanso mphamvu yomatira ya zomatira bwino. Magulu ogwira ntchito monga ma hydroxyl ndi etha m'mapangidwe ake a maselo amatha kupanga ma hydrogen bond ndi zochitika zina zakuthupi ndi zamankhwala ndi pamwamba pa adherend, potero kupititsa patsogolo zomatirazo. Izi zimapangitsa ma cellulose ether kukhala abwino kwambiri polumikizana ndi mapepala, matabwa, zoumba ndi zina. Kusinthasintha kwa ma cellulose ethers kumapangitsa zomatira kumamatira bwino komanso kusavuta kumanga, kulola kuti igwiritse ntchito bwino kwambiri pamagawo osiyanasiyana.
4. Sinthani kukhazikika ndi kukana kuterera
Pomanga zomatira kapena zomatira zowoneka bwino kwambiri, ma cellulose ether amathanso kukulitsa kukana kwadongosolo. Ma cellulose ether amatha kupanga maukonde dongosolo mu binder, kuchepetsa fluidity wa binder, kotero kuti binder TACHIMATA amakhalabe mawonekedwe khola ndipo sadzatha kuzembera chifukwa cha mphamvu yokoka kapena zinthu zakunja, makamaka N'kofunika kwambiri mu mapangidwe zomangamanga monga matailosi anayala. . Kuphatikiza apo, ether ya cellulose imathanso kupatsa zomatira zabwino zotsutsana ndi kukhazikika, kupewa delamination panthawi yosungira ndikugwiritsa ntchito, ndikuwonetsetsa kuti zomatirazo zimakhala zofanana komanso zanthawi yayitali.
5. Kupititsa patsogolo ntchito yomanga
Cellulose ether ali ndi lubricity kwambiri ndi dispersibility, amene kwambiri bwino workability ake zomatira. Zomatira pogwiritsa ntchito cellulose ether sizosavuta kugwiritsa ntchito, komanso zimatha kupanga zomatira zosalala komanso zofananira popanda kuwonjezera makulidwe, kuchepetsa zingwe pakumanga ndikuwongolera luso la ogwiritsa ntchito. Panthawi imodzimodziyo, kugwiritsa ntchito cellulose ether kungathenso kuchepetsa kuchepa kwa zomatira, kuchepetsa kusweka kapena kupukuta mavuto pambuyo popaka, ndikuwongolera kukhazikika ndi kulimba kwa wosanjikiza womangira.
6. Limbikitsani kukana kuzizira kozizira
M'malo ena apadera ogwiritsira ntchito, zomatira zimafunika kuwongolera kangapo kozizira, monga kumanga panja, mayendedwe ndi madera ena. Ma cellulose ether ali ndi kukana kwambiri kwa kuzizira kwa thaw, komwe kumatha kukhalabe kukhazikika kwa zomatira pansi pa kutentha kochepa komanso kuteteza zomatira kuti zisawonongeke panthawi yachisanu. Kupyolera mu mawonekedwe ake okhazikika a maselo, cellulose ether imatha kusunga zomatira zomangira ngakhale kusintha kwa kutentha, kuzipangitsa kukhala zodalirika pansi pa nyengo yoipa. Izi ndizofunikira makamaka pamakina omatira omwe amafunikira nthawi yayitali panja.
7. Kuteteza chilengedwe
Monga chochokera ku cellulose wachilengedwe, ma cellulose ether ali ndi biodegradability yabwino kwambiri komanso kuteteza chilengedwe. Mosiyana ndi ma polima opangira, ma cellulose ethers amachokera kuzinthu zongowonjezedwanso ndipo sangawononge kwambiri chilengedwe mukatha kugwiritsa ntchito. Kuonjezera apo, ma cellulose ethers ali ndi mpweya wochepa wa volatile organic compounds (VOC) panthawi yopanga ndikugwiritsa ntchito, ndipo amatsatira zofunikira za malamulo amakono a zachilengedwe. Choncho, pakupanga mapangidwe a zomatira zomwe zimateteza chilengedwe, ma cellulose ethers pang'onopang'ono amakhala okhuthala komanso zomatira. Binder zopangira.
8. Ntchito zosiyanasiyana
Chifukwa cha kusinthasintha kwawo, ma cellulose ethers amagwira ntchito yofunika kwambiri pakuyika zomatira m'mafakitale angapo. Choyamba, pa ntchito yomanga, ma cellulose ethers amagwiritsidwa ntchito kwambiri pa zomatira za simenti ndi gypsum kuti apereke ntchito yabwino yomanga ndi mphamvu zomangira. Kuphatikiza apo, ma cellulose ethers amagwiritsidwanso ntchito pakuyika ndi zomatira zamapepala. Kusunga kwawo madzi ndi kukhuthala kwawo kumapangitsa kuti pepala likhale lolimba komanso lolimba. Ma cellulose ethers amagwiritsidwanso ntchito mu guluu wamankhwala, guluu wazakudya ndi zina. Chifukwa cha zinthu zawo zopanda poizoni, zopanda fungo komanso zokhazikika, zimakwaniritsa zofunikira zomatira m'minda iyi.
Monga multifunctional polima zakuthupi, mapadi ether ali ndi chiyembekezo yotakata ntchito mu zomatira. Imawongolera kwambiri ntchito zomatira ndikukwaniritsa kufunikira kwa zomatira zapamwamba kwambiri m'mafakitale amakono ndi zomangamanga kudzera muzochita zingapo monga kukhuthala, kusunga madzi, kukonza zomatira, kukulitsa bata, ndikuwongolera magwiridwe antchito. Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo komanso kuchuluka kwa zomwe anthu amafuna pakuteteza chilengedwe, ntchito ya ma cellulose ethers mu zomatira idzakhala yofunika kwambiri, ndipo chiyembekezo chamtsogolo chidzakhala chokulirapo.
