Zipangizo zopangidwa ndi Gypsum zimagwiritsidwa ntchito kwambiri pomanga chifukwa champhamvu, kulimba komanso kukana moto.Zidazi zimapangidwa ndi gypsum, mchere womwe umapezeka m'miyala ya sedimentary, ndi madzi.Zipangizo zopangidwa ndi gypsum zimagwiritsidwa ntchito kwambiri pamakoma, denga ndi pansi m'nyumba zogona, zamalonda ndi zamafakitale.
Hydroxypropyl methylcellulose (HPMC) ndi hydroxyethyl methylcellulose (HEMC) ndi nonionic cellulose ethers omwe amagwiritsidwa ntchito pomanga.Amachokera ku ma polima achilengedwe ndipo ndi ma polima osungunuka m'madzi.Amakhala ndi zinthu zambiri zomwe zimawapangitsa kukhala abwino kwa zida zopangidwa ndi gypsum.
Nkhaniyi iwunika maubwino ambiri ogwiritsira ntchito HPMC ndi HEMC muzinthu zopangidwa ndi gypsum.
1. Kuwongolera magwiridwe antchito
Ubwino umodzi wogwiritsa ntchito HPMC ndi HEMC muzinthu zopangidwa ndi gypsum ndikutha kupititsa patsogolo luso lawo.Ma cellulose ethers akawonjezeredwa kusakaniza, amawonjezera mphamvu yogwira madzi a simenti ndikuwongolera kusakaniza, kufalikira ndi kugwedeza.
Zotsatira zake, zida za gypsum zakhala zosavuta kugwirira ntchito ndipo omanga amatha kusakaniza, kuziyika ndikuzipanga molingana ndi zomwe akufuna.Katunduyu ndi wofunikira kwambiri pama projekiti omwe amafunikira mapangidwe ocholokera kapena mapeni ocholoka.
Kuphatikiza apo, kumangidwa bwino kumathandizira ntchito yomanga mwachangu, kupulumutsa makontrakitala ndi makasitomala nthawi ndi ndalama.
2. Limbikitsani kumamatira ndi kumamatira
Ubwino winanso wofunikira wogwiritsa ntchito HPMC ndi HEMC muzinthu zopangidwa ndi gypsum ndikutha kukulitsa kulumikizana ndi kumamatira.Ma cellulose ethers amathandizira kulumikizana pakati pa chinthucho ndi gawo lapansi, zomwe zimapangitsa kuti pakhale mgwirizano wamphamvu, wokhalitsa.
Katunduyu ndi wofunikira kwambiri pama projekiti okhudzana ndi malo okhala ndi chinyezi chambiri, monga mabafa, khitchini kapena maiwe osambira.Kulumikizana kolimba komanso kumamatira kumateteza zinthu kuti zisang'ambe, kusenda kapena kufota, ngakhale pakakhala zovuta.
3. Wonjezerani kukana madzi
HPMC ndi HEMC amadziwikanso chifukwa cha kuthekera kwawo kukonza kukana madzi.Akawonjezeredwa ku zinthu zopangidwa ndi gypsum, ma cellulose ethers amapanga chitetezo chozungulira tinthu ting'onoting'ono, kuteteza madzi kuti asalowe pamwamba.
Izi ndizofunikira kwambiri pamapulojekiti omwe amafunikira kukana madzi ambiri, monga zipinda zapansi, maziko kapena ma facade.Kutetezedwa kwamadzi kumachepetsa chiopsezo cha kuwonongeka kwa chinyezi, nkhungu kapena mildew, kukulitsa moyo wa kapangidwe kake.
4. Rheology yabwino kwambiri
Rheology ndi sayansi yomwe imaphunzira mapindikidwe ndikuyenda kwa zinthu zomwe zimapanikizika.HPMC ndi HEMC amadziwika ndi rheology yawo yabwino kwambiri, kutanthauza kuti akhoza kusintha mamasukidwe akayendedwe, elasticity ndi plasticity wa zipangizo gypsum ofotokoza.
Izi ndizothandiza makamaka pamapulojekiti omwe amafunikira kusasinthika kosiyanasiyana, monga pansi pawokha, utoto wokongoletsa kapena zoumba.Rheology yabwino kwambiri imalola kuti zinthuzo zizigwirizana ndi mawonekedwe osiyanasiyana, makulidwe ndi mawonekedwe, zomwe zimapangitsa kuti pakhale mawonekedwe osalala, ofanana.
5. Kupititsa patsogolo mpweya
Aeration ndi njira yobweretsera tinthu ting'onoting'ono ta mpweya mu osakaniza kuti zinthuzo zisamatenthedwe bwino, zisamayende bwino komanso zizilimba.HPMC ndi HEMC ndi zida zabwino kwambiri zophunzitsira mpweya, kutanthauza kuti amawonjezera kuchuluka ndi kukula kwa thovu la mpweya muzinthu zopangidwa ndi gypsum.
Izi ndizofunikira kwambiri pamapulojekiti omwe amafunikira kukana kuzizira kwambiri, monga mipanda yakunja, milatho kapena tunnel.Kuwongolera kwa mpweya kumalepheretsa zinthu kung'ambika, kusenda kapena kuwonongeka chifukwa cha kusintha kwa kutentha, kuchepetsa mtengo wokonza ndikuwongolera chitetezo chanyumba.
Pomaliza:
Kugwiritsa ntchito HPMC ndi HEMC muzinthu zopangidwa ndi gypsum kuli ndi maubwino ambiri pantchito yomanga.Ma nonionic cellulose ethers awa amathandizira kusinthika, kumawonjezera kumamatira ndi kumamatira, kumawonjezera kukana kwamadzi, kumapereka ma rheology abwino ndikuwongolera kutsekeka kwa mpweya.
Zinthuzi sizimangowonjezera ubwino wa zomangamanga, komanso zimachepetsa ndalama, zimachulukitsa zokolola, komanso zimalimbitsa chitetezo cha ogwira ntchito yomanga ndi ogwiritsa ntchito.Choncho, kugwiritsa ntchito HPMC ndi HEMC mu zipangizo zopangidwa ndi gypsum kungakhale chisankho chabwino komanso chanzeru pa ntchito iliyonse yomanga.
